Extensive surgery in metastatic testicular cancer.

Surgery remains an important component in the multimodal treatment of patients with advanced testicular cancer. Recently, however, the indications for post-chemotherapy residual tumor resection have changed. Patients with advanced seminoma very rarely need surgical resection of the residual disease after standard chemotherapy. In contrast, patients with high stage non-seminomatous testis cancer must undergo post-chemotherapy surgery in most cases. Surgical resection in metastatic disease may also be necessary in patients with recurrent tumors, patients with persisting marker elevation during chemotherapy and patients with late relapses. Post-chemotherapy residual tumor resections, "redo"-retroperitoneal tumor operations and other salvage resections are often technically demanding procedures with unusual surgical approaches that require individualized perioperative planning in order to reduce morbidity. This paper summarizes the current indications for post-chemotherapy surgery and discusses various surgical approaches and techniques, perioperative management recommendations, as well as complications of these extensive resection procedures.
