[Long-term outcome of testicular seminoma in 294 patients]

To analyze the correlation of long-term survival with the treatment strategies in patients with testicular seminoma.

Clinical data of 294 patients with testicular seminoma treated in our hospital between 1959 and 2004 were collected and analyzed. The median age of the patients was 37 years (range 13 - 70 years). Among them, 260 were in stage I disease, 16 in stage II, and 18 in stage III. The patients were treated by surgical resection plus chemotherapy and/or radiotherapy. The survival rate was calculated using Kaplan-Meier method and log-rank test using SPSS 13.0 software.

The overall 5-, 10-, 20- and 30-year survival rates in this series were 92.1%, 91.8%, 85.5% and 71.4%, respectively. The major prognostic factor was found to be clinical stage. The patients with adjuvant chemotherapy after orchiectomy had better 10-year survival than the patients without (97.5% vs. 79.2%, P = 0.001). For stage II/III patients, the patients with chemotherapy and the patients with chemotherapy plus radiotherapy had a similar progression-free survival (PFS) and overall survival (OS) (P > 0.05).

Testicular seminoma is sensitive to chemotherapy and radiotherapy, and a good cure rate can still be achieved in the relapsed patients with a salvage treatment. Therefore, wide excision and long-term chemotherapy should be avoided in order to maintain the quality of life in those patients.
