title: Orchiectomy alone in the treatment of clinical stage I nonseminomatous germ cell tumor of the testis.
abstract: Forty-five patients with clinical stage I nonseminomatous germ cell tumor of the testis (NSGCTT) were entered in a prospective clinical trial to receive no treatment other than orchiectomy until clinical evidence of relapse. Of this group, 36 patients (80%) have been continuously free of disease for a median duration of 19.5 months after orchiectomy. Nine patients (20%) have relapsed, eight within seven months of orchiectomy. Seven of nine relapsing patients have been rendered free of disease with chemotherapy and/or surgery for a median duration of seven months (range, one to 33 months) after completion of treatment; the other two patients are presently under treatment although one has progressive disease. The relapse rate was higher in patients with embryonal carcinoma than in those with teratocarcinoma, 57% versus 17%. These preliminary results imply that the omission of routine lymphadenectomy or lymph-node irradiation in clinical stage I NSGCTT deserves further trial.
