Morbidity and mortality associated with intraoperative radiotherapy

Area of Science:

• Oncology
• Surgical Oncology
• Radiation Oncology

Background:

• Intraoperative radiation therapy (IORT) is a specialized treatment modality used in cancer surgery.
• Evaluating the safety and morbidity associated with IORT is crucial for its clinical application.

Purpose of the Study:

• To assess the morbidity and mortality associated with intraoperative radiation therapy (IORT) in abdominal surgery.
• To compare complication rates in patients treated with IORT to historical controls.

Main Methods:

• A retrospective review of 67 patients treated with IORT at LDS Hospital from May 1984 to July 1988.
• Classification of complications into major (requiring reoperation or resulting in death) and minor categories.
• Comparison of complication rates with historical controls undergoing similar surgeries before IORT availability.

Main Results:

• Twelve major complications occurred, with three resulting in death.
• Nonfatal complications included anastomotic leak (5), wound dehiscence (1), gastric outlet obstruction (1), and bowel obstruction (1).
• Complication rates were similar when compared to historical controls, indicating IORT did not add to surgical morbidity.

Conclusions:

• Intraoperative radiation therapy (IORT) did not increase the morbidity associated with aggressive abdominal surgery at this institution.
• The safety profile of IORT in this patient cohort suggests it can be safely integrated into surgical oncology protocols.
• Further research may explore long-term outcomes and refine IORT techniques for enhanced patient benefit.
