Urinary Tract Resections as Part of Debulking Surgery for Locally Advanced Endometrial Stromal Sarcomas.

In Vivo 2020 Mar-Apr;34(2):793-797

"Carol Davila" University of Medicine and Pharmacy, Bucharest, Romania.

Background/aim: Although very rare tumors, uterine sarcomas are extremely aggressive gynecologic malignancies being responsible for a significant number of gynecological cancer-related deaths. However, in such cases, it seems that cytoreductive surgery might increase the lifespan if debulking to no residual disease is achieved.

Patients And Methods: We present a case series of three patients diagnosed with endometrial stromal sarcomas in which urinary tract resections were needed in order to maximize the debulking effort. Read More
