OBJECTIVES: To assess whether the use of an organ-specific treatment could improve event-free survival (EFS) and overall survival as endpoints in testicular lymphoma in the early stage: IE and IIE.
METHODS: Thirty-four patients were selected to be treated with orchiectomy following six cycles of anthracycline-based combined chemotherapy and radiotherapy (scrotum and contralateral testis in stage IE, contralateral testis and lymph nodes in stage IIE). Prophylaxis to the central nervous system was administered with four monthly cycles of a high dose of methotrexate: 6 g/m2.
RESULTS: Complete response was achieved in 33 cases (97%). However, relapses continue to be the rule; at a median follow-up of 74 months (range 61-120), 21 patients relapsed. Thus, actuarial curves at 5 years were 32% for EFS and 30% for overall survival, because all patients with failure and relapse died of tumor progression. Relapses were observed in uncommon sites: lung, bone marrow and as disseminate disease; no relapses were observed in irradiated sites of the central nervous system.
CONCLUSIONS: Testicular lymphomas remain a problem as regards defining the optimal treatment. The use of a specific treatment based on organ-involved sites did not show any improvement in outcome. It is evident that more specific therapies need to be explored.
