This review updates management strategies for malignant rectal polyps. Accurate risk stratification is key to determining which patients require oncological resection for these complex cases.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Oncology
Background:
- Malignant rectal polyps present unique management challenges.
- Distinguishing them from colonic counterparts is crucial.
Purpose of the Study:
- To provide a contemporary update on management approaches for malignant rectal polyps.
- To discuss current options and considerations for these lesions.
Main Methods:
- A comprehensive literature review was conducted.
- Databases searched included PubMed, Embase, and Cochrane.
- English-language publications were prioritized.
Main Results:
- Histopathological features (margins, invasion depth, grade, LVI, budding) predict lymph node metastasis risk.
- Transrectal excision is recommended for complete polyp removal and margin assessment.
- Total neoadjuvant therapy and "watch and wait" strategies complicate management.
Conclusions:
- Effective management hinges on precise risk stratification of patients.
- Identifying patients who will benefit from oncological resection is paramount.
