Abstract

INTRODUCTION:

Multivisceral resection is occasionally needed to obtain clear margins in patients with transmural rectal cancer. Most series demonstrate equivalent outcomes between those patients who undergo multivisceral resections and those who do not, provided an R0-resection is achieved. This study focuses solely on patients who received neoadjuvant treatment for clinically transmural rectal cancers and underwent a local multivisceral R0-resection.

METHODS:

A retrospective, single center analysis of consecutive series of patients who received a surgical R0-resection after neoadjuvant treatment for a clinically transmural, non-metastatic, primary rectal cancer. All patients were operated on between 2004 and 2015.

RESULTS:

A total of 279 patients was included, of whom 29 patients underwent a local multivisceral R0-resection (LMVR). These patients were more often female and less often diagnosed through screening. Pathologic AJCC-staging was significantly lower for non-LMVR patients, with more favorable tumor characteristics. LMVR patients demonstrated higher rates of distant disease recurrence, and impaired survival, even after adjusting for disease stage.

CONCLUSION:

An R0-resection after neoadjuvant therapy led to comparative local control of disease; however, patients with multivisceral resection had more distant recurrence and impaired survival, compared to those did not undergo a multivisceral resection. Further research should determine optimal postoperative care.
