Background
The objective of this study was to critically evaluate current literature on outcomes following multivisceral resection (MVR) in colorectal cancer (CRC). Adequate surgical resection with clear margins is imperative in achieving long-term survival in colorectal cancer. Where there is adherence to or invasion of adjacent organs, (MVR) may be needed to achieve complete disease clearance.
Methods
A systematic review of MVR in CRC was performed. Pubmed/Medline and Cochrane databases were searched for English language articles from 1995 to 2012 using a predefined strategy. Retrieved abstracts were independently screened for relevance and data extracted from selected studies by 2 researchers. Results are reported as weighted means.
Results
Included were 22 studies comprising 1575 patients (87.0 % primary colorectal cancer; 13.0 % recurrent, 63.8 % rectal; 36.2 % colon). The most common organs resected were the bladder and reproductive organs. The perioperative mortality was 4.2 % with morbidity of 41.5 % (95 % CI, 40.8–42.2 %). The overall 5-year survival rate was 50.3 % (95 % CI, 49.9–50.8 %). Surgery for recurrence was associated with worse outcomes than primary tumors with 5-year survival 19.5 % (95 % CI, 17.8–21.1 %) for recurrent rectal cancer and primary rectal tumors 5-year overall survival 52.8 % (95 % CI, 52.0–53.8 %). R0 resection was the strongest factor associated with long-term survival.
Conclusions
Multivisceral resection provides the best possibility of long-term survival in locally advanced primary colorectal cancer in which a clear margin has been achieved.
