Abstract
Patterns of failure were analyzed in 30 patients with testicular non-Hodgkin's lymphoma: 16 had stage IE disease, ten had stage IIE, and four had stage IV. After orchiectomy, two of the 16 patients with stage IE disease received no additional therapy, one received multiagent chemotherapy, and 13 received pelvic and para-aortic radiation. Twelve patients with stage IE disease had progression, and the median time to progression was 12 months. Of the 14 patients with extratesticular involvement (stage IIE or IV), one (stage IV) received no treatment after orchiectomy, three (stage IIE) received para-aortic and pelvic radiation, and ten (seven stage IIE and three stage IV) received multiagent chemotherapy with or without radiation. Eight of the patients with stage IIE or IV disease had progression, and the median time to progression was 11 months. Widespread extranodal progression was observed in 17 of the 20 patients who had progression. The tendency of testicular lymphoma for early systemic progression suggests a need for multiagent chemotherapy in initial management.
