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) (21 vs. 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.
