Patterns of outcome and prognostic factors in primary large-cell lymphoma of the testis in a survey by the international extranodal lymphoma study group

Abstract

Purpose: To determine clinical features and patterns of outcome of primary testicular diffuse large B-cell lymphomas (DLCL). Patients and Methods: A retrospective international survey of 373 patients with primary testicular DLCL. Results: Most patients presented with localized disease (stage I to II), and the median age at diagnosis was 66 years (range, 19 to 91 years). Anthracycline-based chemotherapy was administered to 255 patients (68%), and prophylactic intrathecal chemotherapy was given to 68 patients (18%); 133 patients (36%) received prophylactic scrotal radiotherapy.
