Summary
Intraoperative radiotherapy (IORT) improves survival and local control for colorectal cancer patients with involved surgical margins. Further research is needed to optimize this specialized treatment.
Area of Science:
- Oncology
- Surgical Oncology
- Radiation Oncology
Background:
- Advanced and recurrent colorectal cancer require specialized multidisciplinary management.
- Intraoperative radiotherapy (IORT) is a key component in managing complex colorectal cancer cases.
Purpose of the Study:
- To review the role and effectiveness of IORT in colorectal cancer management.
- To assess IORT's impact on survival and local control in patients with involved surgical margins.
Main Methods:
- Literature search of Medline, Embase, Ovid, and Cochrane databases.
- Inclusion of English language studies on IORT for primary and recurrent colon and rectal cancers.
- Analysis of retrospective studies reporting on IORT outcomes.
Main Results:
- Many studies indicate improved survival and local control with IORT for involved surgical margins.
- Results are primarily derived from retrospective studies.
- Associated morbidity with IORT treatment has been noted.
Conclusions:
- Intraoperative radiotherapy (IORT) plays a role in colorectal cancer management.
- Further research is essential to optimize IORT application.
- Evidence from retrospective studies suggests benefits, but prospective research is needed.
