title: Outcome of young patients with rectal adenocarcinoma.
abstract: BACKGROUND
  There is an increase in the incidence of rectal carcinoma (RC) in young patients.
  
  
  METHODS
  We analyzed 175 patients with sporadic RC which were divided in two groups according their age: 24 patients ≤40 years and 151 patients >40 years and the two groups were compared in order to determine if the outcomes (especially overall 5-year survival) were different.
  
  
  RESULTS
  Overall 5-year survival was similar between groups (67.1% for patients over 40 years and 70.4% for those under 40 years, P=0.803). The only differences found were in some clinicopathologic features: patients <40 years showed more dissected lymph nodes (LNs) (21vs. 15, P=0.035) and more LN metastasis (54.2%vs. 39.1%, P=0.048). In multivariate analysis factors associated with worse survival were incomplete resection and no use of neoadjuvant therapy. Age did not demonstrate prognostic value (P=0.077).
  
  
  CONCLUSIONS
  RC in people ≤40 years demonstrated greater number of LN harvested and LN metastases but oncologic outcomes, especially 5-year overall survival, were similar between groups.
