Summary
Local excision offers a curative or palliative option for rectal cancer with minimal morbidity. Accurate staging via endorectal sonography identifies suitable T1 distal rectal cancer patients, ensuring low recurrence risk.
Area of Science:
- Oncology
- Surgical Oncology
- Gastroenterology
Background:
- Local excision aims for rectal cancer cure or palliation with reduced morbidity.
- Accurate patient selection is crucial to prevent local recurrence after rectal cancer treatment.
Purpose of the Study:
- To evaluate the role of local excision in treating rectal cancer.
- To identify patient selection criteria for local excision to minimize recurrence.
- To explore the utility of endorectal sonography in preoperative staging.
Main Methods:
- Utilizing endorectal sonography for precise preoperative staging of rectal cancer.
- Selecting patients with ultrasound stage T1 distal rectal cancer and favorable histology for local excision.
- Performing thorough pathologic examination of excised specimens to determine treatment decisions.
Main Results:
- Endorectal sonography enhances accuracy in preoperative staging of rectal cancer.
- Patients with T1 distal rectal cancer and well-to-moderately differentiated histology are candidates for local excision with low morbidity and recurrence risk.
- Pathologic features guide final therapeutic decisions post-excision.
Conclusions:
- Local excision is a viable option for select T1 distal rectal cancer patients.
- Neoadjuvant therapy followed by local excision shows promise for advanced or very distal tumors with a complete response.
- Further research is needed to define the role of adjuvant therapy post-local excision.
