Clinical features of testicular lymphoma.

Testicular lymphoma is a rare condition, so large scale prospective studies are difficult to conduct. Consensus regarding standard treatment is lacking. This study retrospectively reviewed 22 patients with testicular lymphoma. One patient with diffuse large B-cell lymphoma (DLBCL) was lost to follow-up after diagnosis. Two patients with Burkitt's lymphoma had poor outcomes regardless of treatment. Thus, we analyzed the clinical features, treatments, and outcomes of 19 patients with DLBCL. The median progression-free and overall survival was 28.3 and 36.3 months, respectively. A good response to treatment was a favorable prognostic factor. Because of the high relapse rate, the outcome is poor for testicular lymphoma. Therefore, long-term follow-up is strongly recommended.
