| Popis: | PURPOSE A survey of stage I testicular tumors in the Chugoku-Shikoku district was taken in order to explore the clinical characteristics. PATIENTS AND METHODS Three hundred and forty eight cases of stage I testicular tumor treated at 46 facilities in the Chugoku-Shikoku district between 1984 and 1992 were collected. Subjects' background factors, treatment methods and prognosis were studied. RESULTS Tissue types were 249 (71.6%) seminoma and 99 (28.4%) non-seminoma. Adjuvant therapy for seminoma cases included 138 post-operative radiotherapy (4 recurrences, 3 cancer deaths), 57 chemotherapy (no recurrences, 2 contralateral testis tumor cases) and 48 were under surveillance (no recurrence). Adjuvant therapy for non-seminoma cases included 47 chemotherapy (1 recurrence) and retroperitoneal lymph node dissection was performed on 6 cases. Forty cases were under surveillance (1 recurrence). Of 8 (2.3%) cases with recurrence, 6 showed onset within two years and 2 after two years. Four of the 8 cases with recurrence were seminoma (1.1% of seminoma cases) and the other 4 were non-seminoma (4.0% of non-seminoma cases). All 3 (0.9% of all cases) of the cancer death cases were seminoma that received post-operative radiotherapy, while there were no cancer deaths in non-seminoma cases. CONCLUSION Prognosis of stage I testicular tumor is good. Although the recurrence rate was higher in non-seminoma cases, cancer deaths were only observed in seminoma cases. |
