Testicular primary non-Hodgkin's lymphoma (NHL) is said to account for about 5% of all testicular tumors and about 2% of extranodular lymphoma. From a clinical standpoint, we reviewed testicular NHL of stage IE treated at our department over the past 18 years. Among the 865 cases of NHL, 19 (2.2%) were primary testicular NHL, stage IE. The 19 patients had a median age of 62 years (range 48-77 years), all had diffuse B-cell lymphoma. Of the 19 patients, 8 were treated with radiotherapy after high inguinal orchiectomy (Group I), 4 received both postoperative radiotherapy and chemotherapy (Group II), and 7 received additional prophylactic intrathecal chemotherapy (Group III). The 5-year survival rates for Groups I, II and III were 37.5%, 50%, and 100%, respectively. None of the patients receiving prophylactic intrathecal chemotherapy had relapse in the central nervous system and all of them are alive and disease-free. Primary testicular NHL is relatively common among elderly persons, and many patients die as a result of central nervous system recurrence. These results suggest that preventive measures for central nervous system recurrence such as intrathecal injection of anticancer agents should be taken into consideration as early as at the induction of remission. |
