Primary chemotherapy for stage II nonseminomatous germ cell tumors of the testis.

Between 1979 and 1989, 122 patients with clinical stage II testicular nonseminoma were treated with primary platinum-based combination chemotherapy following orchiectomy. Of the patients 58 had Royal Marsden Hospital stage IIA (nodes less than 2 cm. in diameter) and the other 64 had stage IIB (nodes 2 to 5 cm. diameter) disease. With a median followup after chemotherapy of 5.5 years, 118 patients (97%) were disease-free. Two patients died of progressive germ cell tumors, 1 of bleomycin toxicity and 1 of coincidental disease. The 5-year actuarial survival probability was 95% (95% confidence intervals 91 to 99%) and the 5-year failure-free survival probability was 92% (95% confidence intervals 88 to 97%). Tumor substage was not predictive of relapse but did indicate the probability of lymphadenectomy for a post-chemotherapy residual mass since this was performed in 17% of the patients with stage IIA disease and 39% with stage IIB disease (p < 0.05). Resected specimens contained mature teratoma (29), necrosis alone (5) or embryonal carcinoma (1). We conclude that for these clinical stages primary chemotherapy was as effective as primary lymph node dissection and a major operation was avoided in 68% of the cases.
