Combined CRS With HIPEC in Women With Inadvertently Morcellated uLMS

Plain-language summary

For patients with benign tumors who undergo hysterectomy or myomectomy, minimally invasive gynecologic surgery (MIGS) has advantages over traditional laparotomy such as less trauma and faster recovery. The application of comminution technology is helpful for the implementation of MIGS. Uterine leiomyosarcoma (uLMS) is a malignant tumor that is difficult to diagnose preoperatively and is highly invasive. It is often diagnosed as a benign tumor before surgery. Occult uLMS will cause peritoneal dissemination after non-protective comminution surgery, leading to catastrophic outcomes and extremely poor prognosis. Hyperthermic intraperitoneal chemotherapy (HIPEC) is an important method for the treatment of peritoneal disseminated tumors and has been used in the treatment of gastrointestinal tumors and ovarian cancer. Recent studies have reported that it can significantly improve the progression-free survival (PFS) and overall survival (OS) rates of patients with recurrent uLMS and peritoneal metastasis. However, the efficacy and safety of this treatment for patients with accidental non-protective comminution of uLMS remain uncertain. This study will conduct a retrospective study to evaluate the efficacy and safety of CRS-HIPEC as the first-line treatment for accidentally morcellated uLMS.
