Diffuse large-cell lymphoma of the testis.
OBJECTIVE
To evaluate clinical outcome of patients with testicular diffuse large-cell lymphoma treated with conventional-dose systemic chemotherapy.


METHODS
This study is a retrospective analysis of adult patients with testicular diffuse large-cell lymphoma who were treated with a doxorubicin-based chemotherapy regimen at our institution, the Istituto Nazionale Tumori of Milan. Twenty-nine assessable patients, with a median age of 61 years, were identified. Sixteen patients had limited stage (Ann Arbor stage I/II) disease, whereas 13 patients had a testicular mass and distant organ involvement (Ann Arbor stage IV). Patients were retrospectively classified according to the International Prognostic Index.


RESULTS
After a median follow-up of 82 months, 22 patients presented disease progression and 22 patients had died. Actuarial median time to treatment failure and overall survival were 44 and 41 months for patients with limited stage and 9 and 16 months for patients with advanced stage, respectively. Eight patients failed initial treatment, and 14 patients relapsed from clinical remission after a median disease-free time of 17 months (range, 6 to 98 months). Median survival time after progression of lymphoma was 5 months (range, 0 to 22 months). In nine (41%) of the 22 failing patients, the initial site of relapse was either the CNS or the contralateral testis; the remaining patients experienced relapse in multiple extranodal sites.


CONCLUSIONS
Poor prognosis of patients with diffuse large-cell lymphoma calls for more effective treatment strategies, such as high-dose chemotherapy programs for younger patients or specifically designed chemotherapy regimens for patients not suitable for high-dose treatment, with the purpose to provide control of both systemic disease and disease of the CNS and contralateral testis. The potential benefit of contralateral testicular irradiation has to be taken into account in the treatment planning.
