ORGAN SPARING SURGERY FOR MALIGNANT GERM CELL TUMOR OF THE TESTIS
2001
Purpose: We evaluate the indication, technique and long-term outcome of organ preserving tumor resection rather than standard orchiectomy in 73 patients with bilateral testicular germ cell tumors or tumors of a solitary testicle.Materials and Methods: Tumor resection was performed in 73 patients with 52 and 17 metachronous and synchronous bilateral testicular germ cell tumors, respectively, and 4 testicular germ cell tumors of a solitary testicle. Histology of the enucleated germ cell tumor revealed seminoma in 42 (57.5%) patients, embryonal carcinoma in 14 (19.2%), mature teratoma in 11 (15.1%), and mixed and combined germ cell tumors in 6 (8.2%). Mean tumor diameter was 15 mm. (range 5 to 30). Associated testicular intraepithelial neoplasia was diagnosed in 82% of patients who underwent local radiation with 18 Gy.Results: After a median followup of 91 months (range 3 to 191) 72 (98.6%) patients had no evidence of disease and 1 died of systemic tumor progression. No local relapse occurred in 46 patients ...
