[Results of 15 years of treatment of nonseminoma testicular cancer: 84% 5-year survival rate]

Abstract

Objective: To review the results 5 years after treatment of patients with testicular non-seminoma.

Design: Retrospective, descriptive.

Method: The records were studied of the 146 patients treated in Leiden University Hospital, the Netherlands, in 1979-1993 for non-seminoma of the testicle. The median age was 27 years (range: 16-76). The median follow-up duration was 65 months (range: 4-172). The Kaplan-Meier method was used to calculate the recurrence and survival rates.

Results: In all, 21 of the 146 patients died (5-year survival rate: 84%). Five patients died as a result of treatment. A relapse occurred in 14 of the 49 stage I patients after frequent controls according to the European Organization for Research and Treatment of Cancer (EORTC) standards. One of these patients died after he refused further treatment for his relapse (5-year survival rate: 96%), 92 patients, including 13 from the stage I group, were treated according to protocol with chemotherapy because of metastatic disease, of whom 51 underwent surgery following primary treatment. The histology of the resected material showed vital tumour tissue in 14 of the 51 patients (27%). Seven patients never reached complete remission after chemotherapy and died. In 12 of the 92 patients a relapse occurred after chemotherapy; seven of these died despite further treatment. The 5-year survival rate of the 92 patients with metastatic disease was 82%. None of the surviving patients developed a second primary or major pulmonary, renal or auditory problem.

Conclusion: The chance of cure and survival in patients suffering from testicular non-seminoma with the help of chemotherapy and surgery is over 80%. In stage I patients intensive surveillance, and chemotherapy in case of a relapse, is effective. Even patients with metastatic disease have a high probability of being cured with few long-term side effects.
