Testis-sparing surgery in adult patients with germ cell tumors: Systematic search of the literature and focused review
(Elsevier, 2023) Heidenreich, Axel; Seelemeyer, Felix; Altay, Bülent; del Pilar Laguna Pes, Maria
Testis-sparing surgery (TSS) is a guideline-recommended treatment option for men with synchronous or metachronous bilateral testicular germ-cell tumor (GCT) or GCT in a solitary testicle. The tumor volume should not exceed 50% of the total testicular volume and serum concentrations of both testosterone and luteinizing hormone should be within the normal ranges. After tumor enucleation, patients should undergo adjuvant radiation of the testicle in case of germ cell neoplasia in situ. The local relapse rate is approximately 4% if TSS is performed properly. Physiological serum testosterone concentrations are achieved in more than 85% of patients, and approximately 50% of men with intact spermatogenesis can achieve paternity. The risk of systemic metastases is not increased by TSS. Patient summary: Testis-sparing surgery is the treatment of choice for men with testicular cancer in both testes or in men who have just one testis. In more than 85% of patients this approach results in maintenance of normal testosterone levels.
