Summary
En bloc multivisceral resection is effective for locally advanced rectal cancer. Achieving R0 resection and pN0 status significantly improves overall survival in these patients.
Area of Science:
- Surgical Oncology
- Gastrointestinal Surgery
- Rectal Cancer Research
Background:
- Locally advanced rectal carcinoma presents challenges in achieving complete tumor removal.
- Multivisceral resection involves removing the primary tumor along with adjacent invaded organs.
Purpose of the Study:
- To assess the efficacy of en bloc multivisceral resection for locally advanced rectal cancer.
- To identify prognostic factors influencing survival after this procedure.
Main Methods:
- Retrospective analysis of 312 rectal cancer patients from 1994-2005.
- 57 patients underwent en bloc multivisceral resection for locally advanced disease.
- Survival analysis using Kaplan-Meier and Cox regression models.
Main Results:
- Postoperative mortality was 3.5%.
- 1, 3, and 5-year overall survival rates were 96.4%, 81.6%, and 49.0%, respectively.
- Multivariate analysis identified lymph node status (pN0) and R0 resection as independent predictors of survival.
Conclusions:
- En bloc multivisceral resection is a viable option for selected rectal cancer patients.
- Achieving a complete (R0) resection and negative lymph node (pN0) status are critical for favorable outcomes.
- These factors significantly impact overall survival in locally advanced rectal carcinoma.
