[Lung residuals following chemotherapy in patients with stage III nonseminomatous testicular cancer. Report of 4 cases].

Since 1989, 4 patients with Stage III nonseminomatous germ cell tumor of the testis underwent thoracotomy for persistent radiographic masses after systemic chemotherapy. They were treated with multi-drug regimen including cisplatin, vincristine, methotrexate, peplomycin, and etoposide until normalization of tumor markers was obtained. Residual masses of the 4 patients consisted of viable cancer cells in 1 patient, immature teratoma in 1, mature teratoma in 1 and necrosis in 1. Of the 4 patients 3 achieved complete remission and are doing well with no evidence of disease, while the other case with residual viable cancer cells died of renal failure. The key to successful treatment of advanced testicular cancer was considered to be a favorable response to chemotherapy and complete resection of any residual tumors.
