Objective: To assess the clinical features, survival and prognostic factors of primary testicular diffuse large B-cell lymphoma(DLBCL).Methods: A retrospective study of 37 patients with primary testicular DLBCL was carried out from November 2003 to May 2012. Their clinical features, survival and prognostic factors were analyzed.Results: During a median follow-up period of 39.8 months(5.4-93.0 months), the median progression-free survival(PFS) was 26.2 months(95% CI: 0-65 months) and the 3-year overall survival(OS) rate was 78.4%. Within the whole cohort, the factors significantly associated with a superior PFS were limited stage(stage I/II), lactate dehydrogenase(LDH) ≤245 U/L, international prognostic index(IPI) ≤1, primary tumor diameter <7.5 cm, and patients who had complete response(CR) and received doxorubicin-contained chemotherapy(P<0.05). There was a trend toward superior outcome for patients who received combined therapy(surgery/chemotherapy/radiotherapy)(P=0.055). Patients who had CR, primary tumor diameter <7.5 cm and IPI score ≤1 were significantly associated with longer PFS at multivariate analysis.Conclusions: Primary testicular DLBCL had poorer survival. CR, primary tumor diameter and IPI were independent prognostic factors. The combined therapy of orchectomy, doxorubicin-contained chemotherapy and contralateral testicular radiotherapy(RT) seemed to improve survival.
