Aims: To assess outcome in patients with locally advanced rectal cancer undergoing multivisceral resection.
Methods: Retrospective study of 30 consecutive patients (mean age 67.8 years) with primary locally advanced rectal cancer undergoing en bloc multivisceral resection of the organs involved with curative intent between 1998 and 2010. Overall survival, local and distal recurrence, and disease-free survival were analyzed by the Kaplan-Meier method. Risk factors for clinical outcome were obtained using a Cox multivariate model.
Results: Postoperative complications occurred in 76.7% of patients and the in-hospital mortality rate was 10%. The median follow-up was 28.8 months. A total of 19 patients died at follow-up. Of the 11 patients who were alive, 7 were free of disease. In the multivariate analysis, lymph node involvement, stage II, and lymph vascular invasion were significantly associated with survival, and stage III showed a strong trend towards significance. Suture dehiscence (peritonitis and intra-abdominal abscess) showed a significant trend towards a higher local recurrence. Lymph vascular invasion was associated with a higher distant recurrence.
Conclusion: Lymph node involvement was associated with worse survival, whereas stage II and absence of lymph vascular invasion were associated with a better survival. Lymph vascular invasion was associated with a higher distant recurrence.
