Recurrence Pattern of Metastatic Testicular Cancers after Chemotherapy

Abstract

Recurrence pattern of metastatic testicular cancer after the initial treatment was investigated. Seventy-seven patients with metastatic testicular cancer were treated by cisplatin-based chemotherapy. Patients with residual masses after chemotherapy and whose tumor markers were normalized underwent surgical resections. Of the 77 patients, 61 achieved cancer free status and 4 who did not need the study criteria excluded. Recurrences were detected in 12 (21.1%) patients, 2 (7.1%) patients among 28 stage II patients; 10 (34.5%) patients among 29 stage III patients; none (0%) patients among 14 seminoma patients and 12 (27.9%) patients among 43 non-seminoma patients. All recurrences were detected within 17 months (median, 3) after the initial treatment. Of the 12 patients experiencing recurrence, 4 died of cancer. The recurrence rate of the patients in stage III was significantly higher than that in stage II. No recurrence was detected in patients with seminoma. Follow-up studies after treatment should include serum tumor markers and computed tomographic scanning of lung, abdomen and pelvis at defined intervals. Intensive follow-up will be needed especially for the patients in stage III and with non-seminoma. Follow-up within the first two years is especially important in detecting recurrence after chemotherapy.
