Erythropoietin-stimulating agents (ESAs) effectively decrease the transfusion requirements of patients with chemotherapy-induced anaemia (CIA). Recent studies indicate that ESAs increase mortality and accelerate tumour progression. The studies also identify a 1.6-fold increased risk of venous thromboembolism. The ESA labelling was thus revised in Europe and the United States in 2008. This is the first randomised, phase III trial evaluating the efficacy and safety of epoetin-β (EPO), an ESA, dosed in accordance with the revised labelling, which specifies that ESAs should be administered to CIA patients with a haemoglobin level of ≤ 10 g dl⁻¹ and that a sustained haemoglobin level of > 12 g dl⁻¹ should be avoided.
                A total of 186 CIA patients (8.0 g dl⁻¹ ≤ haemoglobin ≤ 10.0 g dl⁻¹) with lung or gynaecological cancer were randomised to receive EPO 36,000 IU or placebo weekly for 12 weeks.Results:The proportion of patients receiving transfusions or with haemoglobin < 8.0 g dl⁻¹ between week 5 and the end of the treatment period as the primary end point was significantly lower in the EPO group (n=89) than in the placebo group (n=92; 10.0% vs 56.4%, P < 0.001). The proportion receiving transfusions was significantly lower in the EPO group (4.5% vs 19.6%, P=0.002). Changes in quality of life were not different. No significant differences in adverse events - for example, the incidence of thromboembolic events was 1.1% for each group - or the 1-year overall survival were observed between groups.
                Weekly EPO administered according to the revised labelling approved by the European Medicines Agency is effective and well tolerated for CIA treatment. Further investigations are needed on the effect of ESAs on mortality. To investigate predictors of survival in Parkinson disease (PD).
                Vital status was determined in 800 subjects enrolled in a clinical trial of deprenyl (selegiline) and tocopherol 13 years earlier.
                Two hundred ninety-six deaths were recorded. There was no difference in the standardized mortality ratios across gender or age group. In univariate analyses, PD-specific variables associated with mortality were increased symmetry of parkinsonism, gait dysfunction as an initial symptom, severity of parkinsonism, and rate of worsening of parkinsonism prior to study enrollment. Cumulative exposure to deprenyl was not associated with mortality. In multivariable analysis, severity of parkinsonism and rate of worsening of parkinsonism remained associated with mortality. A poorer response to levodopa was associated with increased mortality independent of disease severity or dosage of levodopa. Results were unchanged when the analysis was restricted to 747 subjects maintaining a most likely diagnosis of PD throughout 6 years of active follow-up.
                Parkinson disease did not affect survival differently across gender or age groups in this selected group of otherwise healthy clinical trial participants. Severity and rate of worsening of parkinsonism and response to levodopa are strongly related to survival. Several non-randomised trials have shown that transitional-cell carcinoma of the bladder is a moderately chemosensitive tumour. We investigated whether the addition of neoadjuvant cisplatin-based chemotherapy to radical surgery or radiotherapy would improve survival.
                Patients with T2 G3, T3, T4a, N0-NX, or M0 transitional-cell carcinoma of the bladder undergoing curative cystectomy or full-dose external-beam radiotherapy were randomly assigned three cycles of neoadjuvant chemotherapy (cisplatin, methotrexate, and vinblastine, with folinic acid rescue, n=491) or no chemotherapy (n=485). When possible, clinical tumour response was assessed cytoscopically after completion of chemotherapy but before cystectomy or radiotherapy; histopathologically assessed response was on cystectomy samples. We recorded every 6 months locoregional persistence or relapse of tumour, appearance of distant metastases, survival, and cause of death.
                Median follow-up of patients still alive was 4.0 years. 485 patients died, and 78.6% of deaths were due to transitional-cell carcinoma. Chemotherapy mortality was 1% and operative (cystectomy) mortality was 3.7%. Kaplan-Meier curves compared by means of the log-rank test gave a calculated absolute difference between groups in 3-year survival of 5.5% (95% CI -0.5 to 11.0, p=0.075; 55.5% for chemotherapy, 50.0% for no chemotherapy). Median survival in the chemotherapy group was 44 months compared with 37.5 months for the no-chemotherapy group. 32.5% of cystectomy samples contained no tumour after neoadjuvant chemotherapy.
                Three cycles of neoadjuvant chemotherapy before cystectomy or radiotherapy did not give the 10% improvement in 3-year survival that was judged to be necessary for introduction into routine use. The chemotherapy regimen was associated with a higher pathological complete-response rate in primary tumours, but there was no clear evidence that it would increase survival. We performed a multi-institutional randomized trial comparing preoperative chemotherapy followed by surgery with surgery alone for patients with local and operable esophageal cancer.
                Preoperative chemotherapy for patients randomly assigned to the chemotherapy group included three cycles of cisplatin and fluorouracil. Surgery was performed two to four weeks after the completion of the third cycle; patients also received two additional cycles of chemotherapy after the operation. Patients randomly assigned to the immediate-surgery group underwent the same surgical procedure. The main end point was overall survival.
                Of the 440 eligible patients with adequate data , 213 were assigned to receive preoperative chemotherapy and 227 to undergo immediate surgery. After a median possible study time of 55.4 months, there were no significant differences between the two groups in median survival: 14.9 months for the patients who received preoperative chemotherapy and 16.1 months for those who underwent immediate surgery (P=0.53). At one year, the survival rate was 59 percent for those who received chemotherapy and 60 percent for those who had surgery alone; at two years, survival was 35 percent and 37 percent, respectively. The toxic effects of chemotherapy were tolerable, and the addition of chemotherapy did not appear to increase the morbidity or mortality associated with surgery. There were no differences in survival between patients with squamous-cell carcinoma and those with adenocarcinoma. Weight loss was a significant predictor of poor outcome (P=0.03). With the addition of chemotherapy, there was no change in the rate of recurrence at locoregional or distant sites.
                Preoperative chemotherapy with a combination of cisplatin and fluorouracil did not improve overall survival among patients with epidermoid cancer or adenocarcinoma of the esophagus. In the first Nordic cystectomy trial (1986-1989) a chemotherapy combination of cisplatin-doxorubicin and external radiation seemed to improve the long-term survival after cystectomy in patients with stage T3-T4a bladder carcinomas. The aim of this study was to investigate if solely neoadjuvant chemotherapy could influence survival in patients with advanced urothelial bladder cancer undergoing cystectomy.
                The study (1991-1997) recruited 317 patients with T2-T4aNXM0 urothelial bladder tumours. The patients were randomly allocated to three courses of cisplatin-methotrexate or no pretreatment before cystectomy, eight were subsequently excluded due to protocol violation.
                Chemotherapy according to protocol was administered to 74% (115/155) of the patients in the experimental arm. No chemotherapy related mortality was observed. Of remaining patients in the experimental arm, 14 did not receive any chemotherapy, nine discontinued after one course and 14 after two courses due to side effects. Median follow-up time among censored patients was 5.3 years. Estimated 5-year overall survival was 53% in the experimental arm and 46% in the control arm (n.s. log-rank test). The proportion of patients with pathological stage pT0 was 26.4% in the experimental arm and 11.5% in the control arm (p = 0.001). Risk of locoregional relapse and distant metastases was similar in the study arms.
                The chemotherapy regimen was well tolerated. Despite substantial downstaging no statistically significant survival benefit with the neoadjuvant therapy could be seen after 5 years of follow-up. We report the results of a randomized trial carried out by the Swiss Group for Clinical Cancer Research (SAKK) and in which 230 patients with advanced breast cancer receiving concurrently a hormonal treatment (oophorectomy for pre- and tamoxifen for postmenopausal women) were randomly allocated to three different regimens of combination chemotherapy. The therapeutic results registered with the two more intensive combinations (LMP/FVP and LMFP/ADM) were similar with regard to response rates, time to progression and survival. The patients receiving the low-dose chemotherapy lmfp showed a statistically significant lower response rate (32%, P less than 0.001) and a shorter survival (P = 0.03) than the results observed in patients treated with the two other regimens. This difference was particularly pronounced, at least regarding survival, in the following subgroups: postmenopausal women, patients with a poor performance status, dominant visceral lesions, two sites of disease and a disease-free interval longer than 12 months. Patients with bony metastases as dominant lesion fared similarly with all three regimens of chemotherapy. This latter subset of advanced breast cancer patients should probably be spared too intensive cytotoxic treatment. This is, to our knowledge, the first report of a randomized trial showing an evident correlation between response rate and survival in various subgroups of patients with advanced breast cancer treated with different chemotherapeutic regimens. This study examined the effect of frequent nutritional counseling on oral intake, body weight, response rate, survival, and quality of life in patients with cancer of the lung (small-cell), ovary, or breast undergoing cyclic chemotherapy.
                Of 105 assessable patients, 57 were randomized to receive nutritional counseling, and 48 to receive no nutritional counseling and consumption of an ad lib oral intake. The intervention group was counseled to achieve a daily energy and protein intake according to recommended dietary allowances. Counseling was standardized and performed by a trained dietitian, and took place twice monthly during a 5-month period from start of chemotherapy.
                Dietary counseling increased daily energy intake by approximately 1 MJ and protein intake by 10 g over the entire study period. There was no change in the control group. Counseling led to an insignificant increase in body weight, but triceps skinfold measurement increased significantly after 5 months. Response rate and overall survival did not differ between the groups. Quality of life measured by the Quality-of-Life index (QL-index) increased significantly in both groups, but did not differ between groups.
                No clinical benefit could be demonstrated despite long-term and continuous improved food intake in cancer patients with solid tumors undergoing aggressive chemotherapy. Darbepoetin alfa is an erythropoiesis-stimulating agent (ESA) approved for treating chemotherapy-induced anemia. This phase II, double-blind, placebo-controlled study examined the efficacy of darbepoetin alfa for treating anemia of cancer (AoC) in patients not receiving chemotherapy or radiotherapy. Patients were randomized 3:1 to receive darbepoetin alfa (6.75 microg/kg) or placebo every 4 weeks; the end of the study was at week 17. The primary endpoint was the percentage of patients with a hematopoietic response. Secondary endpoints included transfusion incidence and safety parameters. Efficacy analyses were performed on 162 patients in the darbepoetin alfa group and 56 patients in the placebo group. The Kaplan-Meier percentages of patients who achieved a hematopoietic response (darbepoetin alfa, 69%; placebo, 24%) or achieved the target hemoglobin (darbepoetin alfa, 85%; placebo, 50%) differed significantly between treatment groups. The transfusion incidence did not differ between treatment groups probably because of the low baseline transfusion rates in AoC patients. The incidence of adverse events (including on-study deaths) was similar in both groups. In conclusion, darbepoetin alfa appeared to be well tolerated and significantly increased hemoglobin levels in these AoC study patients. This study investigated the role of preoperative chemotherapy in squamous cell cancer of the esophagus.
                A prospective randomized trial was undertaken in 147 patients: 74 received preoperative chemotherapy comprising cisplatin and 5-fluorouracil and 73 had surgical therapy alone. End points were cancer and therapy-related deaths.
                Sixty-six patients (89%) in the chemotherapy group underwent resection compared with 69 (95%) in the control group (p = not significant). Of the 60 patients who had resection after completing the chemotherapy program, 35 (58%) had a significant response, of whom four (6.7%) had a complete pathologic response. Postoperative mortality rates were 8.3% and 8.7% in the chemotherapy and control groups, respectively (p = not significant). Significant downstaging was evident with chemotherapy; curative resections were possible in 67% of these patients compared with 35% in the control group (p = 0.0003). T3 and T4 tumors were found in 67% and 91% of the chemotherapy and control groups, respectively (p = 0.0002). The respective figures for N1 disease were 70% and 88% (p = 0.009). An intent-to-treat analysis of survival showed no significant difference between the two groups. Median survivals were 16.8 and 13 months, respectively (p = 0.17). Of those who completed the chemotherapy and resection, responders fared better than control patients. Median survivals were 42.2 months and 13.8 months, respectively (p = 0.003). Median survival (8.3 months) was worse for nonresponders than for control patients (p = 0.03). The recurrence pattern suggested a significant reduction in locoregional disease with chemotherapy.
                Preoperative chemotherapy was safe and resulted in significant downstaging and an increased likelihood of curative resection. Survival was not better than that in the surgery-alone group, but responders did fare better than nonresponders. Despite technical improvements that have minimized the morbidity and mortality of hepatic surgery, the long-term outcome of resection of hepatic metastases of colorectal cancer remains poor, with the majority of patients experiencing treatment failure in the liver. Because arterial chemotherapy regimens targeted to the liver have demonstrated high response rates, an intergroup trial of adjuvant therapy for patients undergoing hepatic resection of liver metastases from colorectal cancer was initiated.
                Patients with one to three potentially resectable metastases were randomized preoperatively to receive no further therapy (control arm, 56 patients) or postoperative hepatic arterial floxuridine combined with intravenous continuous-infusion fluorouracil (chemotherapy arm, 53 patients). After exclusion of patients identified as ineligible for the planned treatment at the time of surgery, there were 45 control patients and 30 on the chemotherapy arm. The study was powered to evaluate improvement in time to recurrence and hepatic disease-free survival, not overall survival.
                The 4-year recurrence-free rate was 25% for the control arm and 46% for the chemotherapy group (P =.04). The 4-year liver recurrence-free rate was 43% in the control group and 67% in the chemotherapy group (P =.03). The median survival of the 75 assessable patients was 49 months for the control arm and 63.7 months for the chemotherapy arm (P =.60). The median survival of all 109 patients was 47 months for the control arm compared with 34 months for the chemotherapy arm (P =.19)
                These data demonstrate that adjuvant intra-arterial and intravenous chemotherapy was beneficial in prolonging time to recurrence and pre-venting hepatic recurrence after hepatic resection of colorectal cancer. Sixty-two patients with previously untreated limited stage small cell lung cancer were treated in a prospectively randomized trial comparing thoracic irradiation plus combination chemotherapy with VP-16-213, vincristine (Oncovin), cyclophosphamide, and Adriamycin (VOCA) or those same four drugs plus low-dose (40 mg/m2) cisplatin (VOCAP). The addition of the cisplatin in eight courses of planned chemotherapy did not significantly improve either time to tumor progression of survival or alter sites of disease progression. It did, however, worsen the degree and frequency of nausea, vomiting, and myelosuppression. We did not identify any benefit from the usage of low-dose cisplatin as employed in this study. We update Radiation Therapy Oncology Group trial 8911 (USA Intergroup 113), a comparison of chemotherapy plus surgery versus surgery alone for patients with localized esophageal cancer. The relationship between resection type and between tumor response and outcome were also analyzed.
                The chemotherapy group received preoperative cisplatin plus fluorouracil. Outcome based on the type of resection (R0, R1, R2, or no resection) was evaluated. The main end point was overall survival. Disease-free survival, relapse pattern, the influence of postoperative treatment, and the relationship between response to preoperative chemotherapy and outcome were also evaluated.
                Two hundred sixteen patients received preoperative chemotherapy, 227 underwent immediate surgery. Fifty-nine percent of surgery only and 63% of chemotherapy plus surgery patients underwent R0 resections (P = .5137). Patients undergoing less than an R0 resection had an ominous prognosis; 32% of patients with R0 resections were alive and free of disease at 5 years, only 5% of patients undergoing an R1 resection survived for longer than 5 years. The median survival rates for patients with R1, R2, or no resections were not significantly different. While, as initially reported, there was no difference in overall survival for patients receiving perioperative chemotherapy compared with the surgery only group, patients with objective tumor regression after preoperative chemotherapy had improved survival.
                For patients with localized esophageal cancer, whether or not preoperative chemotherapy is administered, only an R0 resection results in substantial long-term survival. Even microscopically positive margins are an ominous prognostic factor. After a R1 resection, postoperative chemoradiotherapy therapy offers the possibility of long-term disease-free survival to a small percentage of patients. A prospective controlled randomized trial testing adjuvant postoperative combination chemotherapy (5-fluorouracil, lomustine (CCNU) and vincristine) versus no adjuvant therapy in patients operated on for Dukes' C colorectal cancer is reported. In total 334 patients aged less than 70 years were recruited: 205 patients with colonic and 99 with rectal cancer, but there were three protocol violations and these cases are excluded from further consideration. Twenty-seven patients had a limited resection of their cancer. After 5 years' follow-up there was no significant difference in the tumour-free survival rate or in the survival rate between the treated and control groups. Twenty-nine of the 147 patients who started chemotherapy discontinued this treatment because of side-effects, mainly from the gastrointestinal tract. In 30 patients treatment was discontinued because of recurrent disease. The conclusion is that systemic administration of combination chemotherapy for colorectal cancer after operation is not worthwhile in routine clinical practice. Of 77 patients with potentially resectable squamous cell carcinoma of the esophagus who were asked to participate in a phase III trial of treatment with either immediate surgery (n = 24) or surgery plus preoperative chemotherapy (n = 22), only 46 agreed to randomization. A priori, 13 patients chose chemotherapy before surgery and 18 patients chose surgery only. The complete chemotherapy program consisted of three cycles with fluorouracil, 1 g/m2 per day for 5 days, and cisplatin, 20 mg/m2 per day for 5 days. The response rate to chemotherapy was 50% (17 of 34 patients). Side effects of therapy were higher than expected based on results of previous phase II studies. Two drug-related deaths were observed. The resectability rate for patients in the surgery only group was 79% (33 of 42 patients) compared with 70% (19 of 27 patients) for patients receiving chemotherapy. The postoperative rates of septic complications (41% [11 of 27 patients] vs 26% [11 of 42 patients]) and respiratory disorders (48% [13 of 27 patients] vs 31% [13 of 42 patients]) were higher for patients with preoperative chemotherapy than for those treated with surgery only. Surgery-related mortality was increased in the chemotherapy group (19% [five of 27 patients]) compared with the surgery only group (10% [four of 42 patients]). Patients responding to preoperative chemotherapy had prolonged survival (median, 13 months) compared with nonresponders (median, 5 months), but the median survival for the chemotherapy group and the surgery only group was identical (10 months). We conclude that the preoperative chemotherapy regime used in this multi-institutional trial neither influences resectability nor increases the overall survival of patients with localized esophageal cancer. However, preoperative chemotherapy is associated with considerable side effects and a high postoperative mortality rate. Forty-eight patients with unresectable gastric cancer were enrolled for a randomized trial of FP (n = 24) vs FEP (n = 24) combination chemotherapy with respect to their effects on survival period. Of these, excluding 7 patients, 21 in FP group were treated with 400 mg/m2 UFT po daily and 50 mg/m2 CDDP i.v. on days 1 and 8 every 4 weeks, and 20 in FEP group were treated with 400 mg/m2 UFT po daily, 50 mg/m2 etoposide iv and 50 mg/m2 CDDP i.v. on days 1 and 8 every 4 weeks. In FP group, 10 PR in primary lesions were observed with an overall response rate of 52.4%. In FEP group, 5 PR in primary lesions were observed with an overall response rate of 35.0%. Toxicities over Grade 3 were anorexia (35%), vomiting (25%), and leukopenia (12%), which were manageable. The 50% survival time in FP and FEP group was 233 and 176 days, respectively. Because of the high response rate and prolongation of the survival period, combination chemotherapy with FP seemed to be useful for the treatment of patients with advanced gastric cancer. The aim of the present study was to examine the outcome of 517 patients undergoing curative surgery for colonic and rectal cancer, and to compare the recurrence and mortality rates in transfused and non-transfused groups of patients. The two groups were evenly matched for age, sex, Dukes' stage and histological differentiation. There were significantly more rectal tumours in the transfused group (P less than 0.01), but the distribution of colonic lesions did not differ. Life table analysis revealed that the transfused patients had a 20 per cent greater probability of recurrence at 5 years (P less than 0.005) and there were 16 per cent more cancer related deaths (P less than 0.01). Even when all rectal cancers were excluded, a similar trend was seen for the colonic lesions: a 24 per cent greater probability of recurrence at 5 years (P less than 0.025) and 15 per cent more cancer related deaths (P less than 0.02). We conclude that blood transfusion may be associated with increased mortality and recurrence in patients undergoing curative surgery for colorectal cancer. The Breast Cancer-Anemia and the Value of Erythropoietin (BRAVE) study evaluated whether epoetin beta would improve survival in patients with metastatic breast cancer (MBC).
                BRAVE was an open-label, randomized, multicenter study in patients with MBC treated with anthracycline- and/or taxane-based chemotherapy. Patients (hemoglobin [Hb] < 12.9 g/dL) were randomly assigned (1:1) to epoetin beta 30,000 U subcutaneously once weekly or control for 24 weeks. The primary efficacy variable was overall survival. Secondary efficacy outcomes included progression-free survival, transfusion- and severe anemia-free survival, Hb response, safety, and quality of life (QoL).
                After 18 months of follow-up, 62 (27%) of 231 patients survived with epoetin beta therapy and 63 (27%) of 232 with control. No difference was detected in overall survival (hazard ratio [HR] = 1.07; 95% CI, 0.87 to 1.33, P = .522) or progression-free survival (HR = 1.07; 95% CI, 0.89 to 1.30, P = .448). There was a statistically significant benefit on transfusion- and severe anemia-free survival compared with control (HR = 0.59; P = .0097). Median Hb level increased with epoetin beta (11.7 g/dL at baseline to 13.3 g/dL at 24 weeks) but did not change with control (11.5 v 11.4 g/dL). Patients receiving epoetin beta experienced more thromboembolic events (TEEs) compared with controls (13% v 6%; P = .012) with no difference in serious TEEs (4% v 3%). Epoetin beta did not significantly improve QoL in this study where patients had a high baseline Hb value.
                In patients with MBC receiving chemotherapy and initial Hb less than 12.9 g/dL, epoetin beta increased Hb. No difference was detected in overall survival. Because of its superiority design, this study cannot, however, exclude clinically important differences in survival with absolute certainty. This phase III study compared the efficacy and safety of bevacizumab combined with standard chemotherapy regimens versus chemotherapy alone as second-line treatment of patients with human epidermal growth factor receptor 2 (HER2) -negative metastatic breast cancer.
                Patients were randomly assigned 2:1 to chemotherapy + bevacizumab or to chemotherapy + placebo. Before random assignment, investigators chose capecitabine, a taxane (paclitaxel, nab-paclitaxel, or docetaxel), gemcitabine, or vinorelbine. Dosing for bevacizumab or placebo was 15 mg/kg every 3 weeks or 10 mg/kg every 2 weeks, depending on chemotherapy regimen. The primary end point was progression-free survival (PFS). Secondary end points included overall survival, PFS by chemotherapy cohort, objective response rate (ORR), duration of objective response, 1-year survival rate, and safety.
                RIBBON-2 enrolled 684 patients (225, chemotherapy + placebo; 459, chemotherapy + bevacizumab). The combination of bevacizumab with chemotherapy demonstrated a statistically significant benefit. Median PFS increased from 5.1 to 7.2 months (stratified hazard ratio for PFS, 0.78; 95% CI, 0.64 to 0.93; P = .0072). The 10% improvement in ORR between the placebo- and bevacizumab-containing arms (39.5% v 29.6%; P = .0193), although not statistically significant, was consistent with previous trials. There was no statistically significant difference in overall survival. The most common grade ≥ 3 adverse events (AEs) related to bevacizumab treatment were hypertension (9.0%) and proteinuria (3.1%). There was an increased number of AEs leading to study discontinuation in the chemotherapy + bevacizumab arm compared with the chemotherapy + placebo arm (13.3% v 7.2%).
                The combination of bevacizumab with commonly used chemotherapies improved PFS in the second-line treatment of patients with HER2-negative metastatic breast cancer, with a safety profile comparable with that in prior phase III studies. The efficacy and safety of weekly administration of epoetin beta (EPO) for chemotherapy-induced anemia (CIA) patients was evaluated.
                One hundred and twenty-two patients with lung cancer or malignant lymphoma undergoing chemotherapy were randomized to the EPO 36 000 IU group or the placebo group. Hematological response and red blood cell (RBC) transfusion requirement were assessed. Quality of life (QOL) was assessed using the Functional Assessment of Cancer Therapy-Anemia (FACT-An) questionnaire.
                Mean change in hemoglobin level with EPO increased significantly over placebo (1.4 +/- 1.9 g/dl versus -0.8 +/- 1.5 g/dl; P < 0.001). The proportion of patients with change in hemoglobin level > or =2.0 g/dl was higher for EPO than those for placebo (P < 0.001). After 4 weeks of administration, the proportion of RBC transfusion or hemoglobin level <8.0 g/dl was significantly lower for EPO than those for placebo (P = 0.046). The changes in the FACT-An total Fatigue Subscale Score (FSS) were less deteriorated with EPO than those with placebo. Progressive disease (PD) did not influence the change in hemoglobin level but there was less decrease in FSS in non-PD patients. No significant differences in adverse events were observed. Thrombovascular events and pure red cell aplasia related to EPO were not observed. Retrospective analysis of survival showing the hazard ratio of EPO to placebo was 0.94.
                Weekly administration of EPO 36 000 IU significantly increased hemoglobin level and ameliorated the decline of QOL in CIA patients over the 8-week administration period. Although the benefit from adjuvant chemotherapy has been clearly established in patients with Dukes' C colon cancer, such benefit has been questioned in patients with Dukes' B disease. To determine whether patients with Dukes' B disease benefit from adjuvant chemotherapy and to evaluate the magnitude of the benefit, compared with that observed in Dukes' C patients, we examined the relative efficacy of adjuvant chemotherapy according to Dukes' stage in four sequential National Surgical Adjuvant Breast and Bowel Project trials (C-01, C-02, C-03, and C-04) that compared different adjuvant chemotherapy regimens with each other or with no adjuvant treatment.
                The four trials included Dukes' B and C patients and were conducted between 1977 and 1990. The eligibility criteria and follow-up requirements were similar for all four trials. Protocol C-01 compared adjuvant semustine, vincristine, and fluorouracil (5-FU) (MOF regimen) with operation alone. Protocol C-02 compared the perioperative administration of a portal venous infusion of 5-FU with operation alone. Protocol C-03 compared adjuvant 5-FU and leucovorin (LV) with adjuvant MOF. Protocol C-04 compared adjuvant 5-FU and LV with 5-FU and levamisole (LEV) and with the combination of 5-FU, LV, and LEV.
                Forty-one percent of the patients included in these four trials had resected Dukes' B tumors. In all four studies, the overall, disease-free, and recurrence-free survival improvement noted for all patients was evident in both Dukes' B and Dukes' C patients. When the relative efficacy of chemotherapy was examined, there was always an observed reduction in mortality, recurrence, or disease-free survival event, irrespective of Dukes' stage, and in most instances, the reduction was as great or greater for Dukes' B patients as for Dukes' C patients. When data from all four trials were examined in a combined analysis, the mortality reduction was 30% for Dukes' B patients versus 18% for Dukes' C patients. The mortality reduction in Dukes' B patients occurred irrespective of the presence or absence of adverse prognostic factors.
                Patients with Dukes' B colon cancer benefit from adjuvant chemotherapy and should be presented with this treatment option. Regardless of the presence or absence of other clinical prognostic factors, Dukes' B patients seem to benefit from chemotherapy administration. Intraperitoneal (IP) chemotherapy has gained enthusiasm in the treatment of ovarian cancer. Despite having a better survival advantage than intravenous (IV) chemotherapy, IP chemotherapy still poses significant morbidity and complications. Identifying the subset of patients who could best benefit from IP chemotherapy, and those who would least benefit from this treatment, thus avoiding potential complications, is critical.
                Between January 2001 and December 2007, 367 patients with stage III epithelial ovarian cancer underwent randomized trial for IP/IV chemotherapy were recruited to construct a nomogram, which is a graphical representation of Cox proportional hazards model adopting six weighted risk factors including age, CA125, IP/IV delivery, stage, histology, and upper abdominal metastases. The nomogram was internally validated for discrimination and calibration. The concordance index was used for quantifying the predictive ability of overall survival with bootstrapping to correct for bias.
                The cycles of completed IP chemotherapy had an impact on overall survival (> or =5 vs. < or =4 cycles, P=0.02). A nomogram for predicting median survival and 5-year survival probability was constructed with a concordance index of 0.72. Upper abdominal tumor metastases (P<0.001) and colon resection (P=0.02) predicted increased chances for early discontinuation of IP chemotherapy.
                At least five IP cycles are needed to achieve better survival. Nomogram can help to identify the subset of patients who can least benefit from IP chemotherapy, thus avoiding potential IP complications and help to facilitate discussion between patient and physician, risk stratification, and help to guide clinical care. The European Lung Cancer Working Party (ELCWP) designed a 3-arm phase III randomised trial to determine the role of accelerated chemotherapy in extensive-disease (ED) small-cell lung cancer (SCLC). Eligible patients were randomised between the 3 following arms: (A) Standard chemotherapy with 6 courses of EVI (epirubicin 60 mg m(-2), vindesine 3 mg m(-2), ifosfamide 5 g m(-2); all drugs given on day 1 repeated every three weeks. (B) Accelerated chemotherapy with EVI administered every 2 weeks and GM-CSF support. (C) Accelerated chemotherapy with EVI and oral antibiotics (cotrimoxazole). Primary endpoint was survival. 233 eligible patients were randomised. Chemotherapy could be significantly accelerated in arm B with increased absolute dose-intensity. Best response rates, in the population of evaluable patients, were, respectively for arm A, B and C, 59%, 76% and 70%. The response rate was significantly higher in arm B in comparison to arm A (P = 0.04). There was, however, no survival difference with respective median duration and 2-year rate of 286 days and 5% for arm A, 264 days and 6% for arm B and 264 days and 6% for arm C. Severe thrombopenia occurred more frequently in arm B but without an increased rate of bleeding. Non-severe infections were more frequent in arm B and severe infections were less frequent in arm C. Our trial failed to demonstrate, in ED-SCLC, a survival benefit of chemotherapy acceleration by using GM-CSF support. A retrospective survey of 38 ovarian cancer patients who developed radiologically confirmed intestinal obstruction was performed. Twenty-six patients underwent surgery. In the surgical treatment group, obstruction was not due to recurrent disease in six cases. The median survival for the group as a whole was 56 days. Patients in the operative group survived significantly longer than those in the non-operative group. There was an operative mortality of 15% and major postoperative morbidity was seen in 42%. Neither the site of the obstruction nor the type of operation influenced survival. No postoperative chemotherapy responses were seen in previously treated patients. Cancer treatment is associated with decline in measured and self-reported physical function and increased pain. In the current study, the authors evaluated the impact of a walking intervention on these outcomes during chemotherapy/radiation.
                Patients with breast, prostate, and other cancers (N=126) were randomized to a home-based walking intervention (exercise) or usual care (control). Exercise dose during the intervention was assessed using a 5-item Physical Activity Questionnaire. Outcome measures were cardiorespiratory fitness, expressed as peak oxygen uptake (VO2) measured during treadmill testing (n=85) or estimated by 12-minute walk (n=27), and self-reported physical function, role limitations, and pain derived from Medical Outcomes Study Short Form 36. Linear regression was used to evaluate pre-to-post intervention change outcomes between groups.
                The mean (standard deviation) age of the patients was 60.2 (10.6) years. Diagnoses included prostate (55.6%) and breast (32.5%) cancer. Treatment included external beam radiotherapy (52.3%) and chemotherapy (34.9%). Exercise patients reported worsening Medical Outcomes Study physical function role limitations by the end of cancer treatment (P=.037). Younger age was associated with improved Medical Outcomes Study physical function (P=.048). In all patients, increased exercise dose was associated with decreased Medical Outcomes Study pain (P=.046), regardless of diagnosis. The percent change of VO2 between prostate and nonprostate cancer patients when adjusted for baseline VO2 and Physical Activity Questionnaire values was 17.45% (P=.008), with better VO2 maintenance in the prostate group.
                Exercise during cancer treatment improves cardiorespiratory fitness and self-reported physical function in prostate cancer patients and in younger patients, regardless of diagnosis, and may attenuate loss of those capacities in patients undergoing chemotherapy. Exercise also reduces the pain experience.
                Copyright (c) 2009 American Cancer Society. Systemic delivery of cytotoxic drugs yields relatively low doses in the liver, a major site of recurrence for colorectal cancer. Giving chemotherapy by means of continuous portal vein infusion (PVI) into the liver during the immediate postoperative period may improve therapeutic efficacy.
                We undertook a meta-analysis to assess the effects on recurrence and survival of administering fluorouracil (5-FU)-based chemotherapy by PVI after colorectal cancer surgery.
                Data on mortality and recurrence were sought for all patients enrolled in randomized trials initiated before 1987 in which a few days (range, 5-7 days) of continuous postoperative PVI of cytotoxic drugs was compared with no further treatment. Data from 10 trials (a promising initial study and nine hypothesis-testing trials) involving about 4000 patients were available for analysis. The main cytotoxic drug in each trial was 5-FU (given with heparin); however, mitomycin C was co-administered in two of the trials. Four trials included an additional control group of patients treated with continuous noncytotoxic PVI of either heparin or urokinase alone; one trial included a second control group of patients treated with continuous systemic infusion of 5-FU. Reported P values are two-sided.
                Among the 3499 patients randomly assigned to receive either cytotoxic PVI or no further treatment, 1557 deaths are known to have occurred. Survival with and without PVI appeared to be the same for the first 2 years; thereafter, it diverged significantly, with the absolute survival difference (i.e., improvement) associated with PVI at 5 years being 4.7 % (standard deviation [SD] = 1.2 %) (P = .006). When just the nine hypothesis-testing trials were considered, the absolute survival difference was 3.6% (SD = 1.2%) (P = .04). If, ignoring any potential for bias in stage assignment, attention was restricted to patients with Dukes' stage A, B, or C disease (88.3% of the total), the absolute effect on 5-year survival for all 10 trials increased to 6.0% (SD = 1.8%) (P = .001); this estimate remained statistically significant when the initial study was excluded (absolute survival difference = 4.8%; SD = 1.8%; P = .01). In contrast to the highly significant reduction in liver metastases seen in the initial study (79% reduction; SD = 15%; P = .00000007), the reduction found in the nine hypothesis-testing trials was not significant (14% reduction; SD = 10%; P = .2). In the trials with additional control groups, survival appeared to be better with cytotoxic PVI than with noncytotoxic PVI or with systemic cytotoxic drug infusion.
                PVI of 5-FU (with or without other cytotoxic drugs) for about 1 week after surgery in patients with colorectal cancer may produce an absolute improvement in 5-year survival of a few percent. Although encouraging, this finding is not statistically secure, and additional evidence from randomized trials involving several thousand more patients is needed. The aim of the QUASAR trial was to determine the size and duration of any survival benefit from adjuvant chemotherapy for patients with colorectal cancer at low risk of recurrence, for whom the indication for such treatment is unclear.
                After apparently curative resections of colon or rectal cancer, 3239 patients (2963 [91%] with stage II [node negative] disease, 2291 [71%] with colon cancer, median age 63 [IQR 56-68] years) enrolled between May, 1994, and December, 2003, from 150 centres in 19 countries were randomly assigned to receive chemotherapy with fluorouracil and folinic acid (n=1622) or to observation (with chemotherapy considered on recurrence; n=1617). Chemotherapy was delivered as six 5-day courses every 4 weeks or as 30 once-weekly courses of intravenous fluorouracil (370 mg/m2) with high-dose (175 mg) L-folinic acid or low-dose (25 mg) L-folinic acid. Until 1997, levamisole (12 courses of 450 mg over 3 days repeated every 2 weeks) or placebo was added. After 1997, patients who were assigned to receive chemotherapy were given fluorouracil and low-dose folinic acid only. The primary outcome was all-cause mortality. Analyses were done by intention to treat. This trial is registered with the International Clinical Trial Registry, number ISRCTN82375386.
                At the time of analysis, 61 (3.8%) patients in the chemotherapy group and 50 (3.1%) in the observation group had missing follow-up. After a median follow-up of 5.5 (range 0-10.6) years, there were 311 deaths in the chemotherapy group and 370 in the observation group; the relative risk of death from any cause with chemotherapy versus observation alone was 0.82 (95% CI 0.70-0.95; p=0.008). There were 293 recurrences in the chemotherapy group and 359 in the observation group; the relative risk of recurrence with chemotherapy versus observation alone was 0.78 (0.67-0.91; p=0.001). Treatment efficacy did not differ significantly by tumour site, stage, sex, age, or chemotherapy schedule. Eight (0.5%) patients in the chemotherapy group and four (0.25%) in the observation group died from non-colorectal cancer causes within 30 weeks of randomisation; only one of these deaths was deemed to be possibly chemotherapy related.
                Chemotherapy with fluorouracil and folinic acid could improve survival of patients with stage II colorectal cancer, although the absolute improvements are small: assuming 5-year mortality without chemotherapy is 20%, the relative risk of death seen here translates into an absolute improvement in survival of 3.6% (95% CI 1.0-6.0). Induction chemotherapy before surgical resection increases survival compared with surgical resection alone in patients with stage IIIA-N2 non-small-cell lung cancer (NSCLC). We hypothesized that, following a response to induction chemotherapy, surgical resection would be superior to thoracic radiotherapy as locoregional therapy.
                Selected patients with histologic or cytologic proven stage IIIA-N2 NSCLC were given three cycles of platinum-based induction chemotherapy. Responding patients were subsequently randomly assigned to surgical resection or radiotherapy. Survival curves were estimated using Kaplan-Meier analyses from time of randomization.
                Induction chemotherapy resulted in a response rate of 61% (95% confidence interval [CI] = 57% to 65%) among the 579 eligible patients. A total of 167 patients were allocated to resection and 165 to radiotherapy. Of the 154 (92%) patients who underwent surgery, 14% had an exploratory thoracotomy, 50% a radical resection, 42% a pathologic downstaging, and 5% a pathologic complete response; 4% died after surgery. Postoperative radiotherapy was administered to 62 (40%) of patients in the surgery arm. Among the 154 (93%) irradiated patients, overall compliance to the radiotherapy prescription was 55%, and grade 3/4 acute and late esophageal and pulmonary toxic effects occurred in 4% and 7%; one patient died of radiation pneumonitis. Median and 5-year overall survival for patients randomly assigned to resection versus radiotherapy were 16.4 versus 17.5 months and 15.7% versus 14%, respectively (hazard ratio = 1.06, 95% CI = 0.84 to 1.35). Rates of progression-free survival were also similar in both groups.
                In selected patients with pathologically proven stage IIIA-N2 NSCLC and a response to induction chemotherapy, surgical resection did not improve overall or progression-free survival compared with radiotherapy. In view of its low morbidity and mortality, radiotherapy should be considered the preferred locoregional treatment for these patients.
ESA treatment in cancer patients increased on study mortality and worsened overall survival. For patients undergoing chemotherapy the increase was less pronounced, but an adverse effect could not be excluded.
