Rectosigmoid Lesion Excision vs. Resection: A Non-Inferiority Randomized Comparison in Advanced Ovarian Cancer
Recruiting now · Not applicable
Conditions studied: Ovarian Cancer (OvCa)
In brief
Colorectum is the most common site of metastasis in ovarian cancer. Regarding intestinal surgery, there is controversy over whether to choose bowel resection or tumor removal, and currently, there are no prospective randomized controlled studies comparing the oncological safety of these two surgical approaches. This study is a prospective randomized trial aimed at comparing the efficacy of rectosigmoid resection versus rectosigmoid-preserving lesion excision in advanced ovarian cancer surgery.
