Vascular Changes and Surgical Risk in Cervical vs. Endometrial Cancer After Radiotherapy: A Retrospective Cohort...

Area of Science:

• Oncology
• Vascular Surgery
• Radiology

Background:

• Radiotherapy (RT) is crucial for cervical and endometrial cancers.
• RT can alter pelvic vasculature, complicating surgery and increasing morbidity.
• Pelvic vascular effects of RT are less understood than those in other regions.

Purpose of the Study:

• To investigate intraoperative vascular changes after pelvic RT.
• To correlate these changes with tumor type, complications, and vascular injury.
• To identify predictors of perioperative morbidity in patients undergoing pelvic oncologic surgery post-RT.

Main Methods:

• Retrospective analysis of 119 patients (cervical/endometrial cancer) post-pelvic RT.
• Recording intraoperative vascular findings and complications.
• Using logistic regression to find predictors of morbidity.

Main Results:

• Perivascular fibrosis (21.8%) and inflammatory thrombosis (10.1%) were common vascular changes.
• Most patients needed no vascular intervention; simple repairs sufficed.
• Cervical cancer patients had more complications (hemorrhage, UTIs); fibrosis was a borderline predictor.

Conclusions:

• Neoadjuvant RT causes vascular changes but not significant major injury in experienced hands.
• Cervical cancer patients are a high-risk group needing specialized care.
• Perivascular fibrosis may indicate operative risk; long-term vascular surveillance is advised.
