BIEL W, Enrique et al. Early and late results after multivisceral resections for T4b colonic cancer. Rev Chil Cir [online]. 2017, vol.69, n.2, pp.139-143. ISSN 0718-4026.  http://dx.doi.org/10.1016/j.rchic.2016.10.006.

Aims: To describe postoperative morbidity and mortality rates in multivisceral resections for T4b colon cancer. Material and methods: Case series of patients diagnosed of T4b colonic adenocarcinoma who underwent multivisceral resection between 2005 and 2014. There were excluded those patients who had metastases, R2 resection and incomplete clinical data. Result variables were morbidity and mortality at 30 days. It was performed descriptive statistic using percentage estimation for categories, average and median for continuous variables and standard deviation or rank as measures of statistical dispersion. It was used Kaplan-Meier method for survival and chi-square and log-Rank for subgroups analysis. Results: From a universe of 483 patients who underwent surgery for colonic adenocarcinoma, whom 71 were staged as T4b, after exclusion criteria were applied it resulted a sample of 46 patients. The small bowel, omentum, abdominal wall and other colonic segment were the more often compromised organs. Postoperative morbidity and mortality were 21.7 and 6.5% respectively. The age, history of adjuvant chemotherapy, presence of microsatellite instability and tumor differentiation had a significant impact in survival. Conclusions: Multivisceral affection in colonic cancer is not uncommon, 9.5% in our series. R0 resection is the treatment of choice. Patient outcome depends on his age, histologic and biologic characteristics of the tumor and adjuvant treatment.
