Standard versus Limited Colon Resection for High Risk T1 Colon Cancer. A Matched Case-Control Study

2014 Journal of Gastrointestinal and Liver Diseases  
& Aims: e National Comprehensive Cancer Network (NCCN) recommends a colectomy in presence of high risk T1 colon polyps considering the risk of incomplete lymph node dissection or presence of residual disease. We evaluated the outcomes of segmental versus standard colon resection for high risk T1 colon cancers, in order to demonstrate if segmental colectomy (SegCR) allows same short-term and oncological results compared to standard radical colectomy (StaCR). Methods. A matched case-control study

One-hundred and two patients with high risk T1 colon cancer a er endoscopic polypectomy, divided in 2 homogeneous groups of 51 cases, were analyzed and intra-operative, post-operative and oncological data were compared. Results. Segmental colectomy allowed less operative time and intra-operative blood loss compared to StaCR (p < 0.001). Hospital stay a er SegCR was shorter compared to StaCR (p < 0.001). No di erences were found in terms of overall morbidity and mortality rates. Five-year actuarial overall, disease-free and disease-speci c survival a er StaCR were similar to SegCR (87%, 96% and 95% vs. 88%, 97% and 94%, respectively, p = 0.51, p=0.33, p=0.78). Conclusions. According to our ndings, SegCR can be a valid alternative to StaCR for high risk T1 colon polyps. Segmental colectomy allows better peri-operative outcomes compared to StaCR ensuring the same oncological long-term outcomes.
