Epidemiologic evaluation shows decreased survival in elderly rectal cancer due to less aggressive treatment.

This research aims to understand why elderly patients with rectal cancer experience lower survival rates compared to younger patients.
Evaluated localized rectal adenocarcinoma cases from the Surveillance, Epidemiology, and End Results database (1991-2002).
Assessed survival rates by age, surgery type, tumor grade, lymph node status, and radiation therapy using regression analysis.
Included 21,390 patients with median age of 68 years.
Each half-decade increase in age ≥70 years raises cancer-related mortality risk by 37% (RR = 1.37; 95% CI, 1.33-1.42).
Elderly patients receive less cancer-directed surgery (OR = 0.56; 95% CI, 0.36-0.63) and undergo more local excision rather than radical surgery (OR = 0.76; 95% CI, 0.72-0.81).
Less radiotherapy is given to elderly patients (OR = 0.64; 95% CI, 0.61-0.67), correlating with an increase in cancer-specific mortality (RR = 1.31; 95% CI, 1.25-1.36).

Chang et al. (2007) studied this question.
