ALMERAYA ORTEGA, Juan et al. Long-term results in the surgical management of rectal cancer: 5 year survival. Cir. gen [online]. 2014, vol.36, n.4, pp.225-231. ISSN 1405-0099.

Introduction: Rectal cancer is a malignant tumor that is characterized by an uncoordinated, autonomous overgrowth located in the rectum. This can be treated with curative intent with any of the following surgical options: local resection, anterior resection with different variants, and abdominal-perineal amputation. The purpose of this work was to perform a descriptive analysis of patients operated on with curative intent for rectal cancer, and evaluate the 5-year survival and prognostic factors determining survival.

Material and Methods: A retrospective observational study was conducted on all patients operated on electively and by open or laparoscopic surgery with curative intent, and a final diagnosis of rectal cancer in the period from January 1st, 2000 to January 1st, 2005.

Results: The study included 97 patients, 53 women (54.6%) and 44 men (45.4%), with: mean age 56.8 + 8.9 years; Comorbidities 34.0%; ASA I 16.5%, 52.6% II, III 30.9%; Anatomical location, 49.5% upper third, 21.6% middle, 28.9% lower. Differentiation grade, 32% well differentiated, 64.9% moderately, 3.1% poorly. Stage IIa 4.1%, IIb 49.5%, IIIa 34%, IIIb 12.4%. Neoadjuvant 32%. Anastomosis dehiscence 1% and 10.3% locoregional recurrence. Overall or actuarial survival at 5 years of 72.2%.

Conclusions: The 5- year survival in patients was adequate in relation to the fi ndings in the literature. Gender comorbidities, ASA physical status, anatomic location of the tumor, degree of differentiation, clinical TNM stage, neoadjuvant, dehiscence, and tumor recurrence are factors that infl uence survival.
