Testis sparing surgery in the treatment of bilateral testicular germ cell tumors and solitary testicle tumors: A single institution experience

Abstract

Background and Objective: To assess the oncologic and functional outcomes of testicular sparing surgery (TSS) based on a single institution experience. Methods: Forty-one patients with bilateral and 3 patients with solitary testicle tumors were referred to our institution. The inclusion criteria for TSS were normal serum testosterone levels, and tumor size (<2 cm). Sperm analysis and hormone status evaluation were performed preoperatively and postoperatively. None of the patients underwent local radiation therapy following TSS for reasons of fertility preservation. Results: A total of 26 TSS were performed in 24 patients. The median follow-up period was 51.0 months. Seven patients developed local recurrence, of which 5 had TIN and were subjected to radical orchiectomy, whereas re-do TSS was done in remaining 2 patients. The overall survival of the study group was 100%, and the presence of testicular intraepithelial neoplasia (TIN) was associated with worse recurrence-free survival (P = 0.031, log-rank). Testosterone values were normal in all of the patients, while 4 patients achieved conception. Conclusions: TSS is acceptable from an oncological point of view, and it enables continuation of a patient's life without lifelong hormonal substitution. Additionally, local irradiation therapy could be delayed in patients with TIN who wish to father children, but with high local recurrence rate. © 2014 Wiley Periodicals, Inc.
