The only curative treatment is complete surgical excision of the tumor, which can be performed even in the case of invasion into large blood vessels, such as the renal vein or inferior vena cava. The 5-year survival rate after successful surgery is 50–60%, but unfortunately, many patients are not surgical candidates. Radiation therapy and radiofrequency ablation may be used for palliation in patients who are not surgical candidates. Minimally invasive surgical techniques remain controversial due to the absence of long-term data, with a particular concern for rates of recurrence and peritoneal carcinomatosis. Chemotherapy regimens typically include the drug mitotane, an inhibitor of steroid synthesis, which is toxic to cells of the adrenal cortex, as well as standard cytotoxic drugs. A retrospective analysis showed a survival benefit for mitotane in addition to surgery when compared to surgery alone. The two most common regimens are cisplatin, doxorubicin, etoposide (EDP) + mitotane, and streptozotocin + mitotane. The FIRM-ACT trial demonstrated higher rates of response and longer progression-free survival with EDP + mitotane than with streptozotocin + mitotane.
