Cytoreductive Surgery plus Hyperthermic Intraperitoneal Chemotherapy for Management of Peritoneal Sarcomatosis: A Preliminary Single Center Experience from Saudi Arabia
Aim. To report our preliminary single center experience with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for management of peritoneal sarcomatosis (PS) Methods. Eleven patients were retrospectively analyzed for perioperative details. Results. Cytoreduction completeness (CC 0/1) was achieved in all patients with median peritoneal cancer index (PCI) of 14 8.9 (range: 3 29) Combination cisplatin doxorubicin HIPEC chemotherapy was used in 6 patients. Five patients received intraoperative radiation therapy (IORT) The median operative time, estimated blood loss, and hospital stay were 8 1.4 hours (range: 6 10) 1000 250 mL (range: 700 3850) and 11 2.4 days (range: 7 15) respectively. Major postoperative Clavien Dindo grade III/IV complications occurred in 1 patient and none developed HIPEC chemotherapy related toxicities. The median overall survival (OS) and disease free survival (DFS) after CRS HIPEC were 28.3 3.2 and 18.0 4.0 months, respectively. The median follow up time was 12 months (range: 6 33) Univariate analysis of several prognostic factors (age, gender, PS presentation/pathology, CC, PCI, HIPEC chemotherapy, and IORT) did not demonstrate statistically significant differences of OS and DFS. Conclusion. CRS HIPEC appear to be feasible, safe, and offer survival oncological benefits. However, definitive conclusions cannot be deduced.
