Resumen

BANNURA C, GUILLERMO et al. Comparative results of the surgical treatment of tumors located in the upper third of the rectum and sigmoid colon. Rev Chil Cir [online]. 2009, vol.61, n.6, pp.538-543. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262009000600008.

Background: Tumors located in the upper third of the rectum can be treated in the same way as sigmoid tumors. This means that mesorrectum excision and neoadjuvant therapies are not necessary. Aim: To compare the results in terms of relapse and survival of elective surgery for sigmoid and upper third rectal tumors. Material and Methods: Retrospective analysis of patients operated for an upper third rectal or sigmoid cancer that were prospectively included in a database and had a minimum follow up of 18 months. Clinical and pathological variables and staging using TNM classification were considered as covariates in the analysis. Results: Fifty patients with a tumor of the upper third of the rectum, aged 30 to 84 years (24 females), with a follow up ranging from 12 to 206 months, and 107 patients with a sigmoid tumor, aged 22 to 91 years (62 females), with a follow up ranging from 13 to 204 months, were analyzed. Seven patients with rectal tumors (14%) and 12 patients with sigmoid tumors (11%), died during follow up (p = NS). Ten years actuarial overall survival was 85% for both groups. Conclusions: No differences in survival or relapse were observed in this group of patients with tumors located in the upper third of the rectum or sigmoid colon. Therefore both types of tumors can be treated in the same way.
