TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['The variation in nodal involvement between age groups has not been thoroughly studied in colon cancer, but it may affect strategies for extent of resection in elderly patients. The objective of our study was to compare nodal involvement in colon cancer patients, with a focus on surgical staging practices in the elderly.', 'We extracted data from the Surveillance, Epidemiology and End Results registry on 208,077 patients diagnosed with stage I-III colon adenocarcinoma between 2000 and 2010. Patients undergoing colon resection, patients with adequate staging with ≥12 lymph nodes examined (LNE, n = 114,351) and with node-positive cancers were compared in age groups using chi-squared test. Relative risk (RR) of node-positive cancer was compared in a multivariable log-linear model, and relative survival in a flexible parametric model.', 'While the rates of colon resection were similar in all age groups, older patients were significantly less likely to have ≥12 LNE (P < 0.0001). When adequately staged, older patients had a significantly lower proportion of node-positive cancers (P < 0.0001). Survival was better in patients with ≥12 LNE, with no significant difference in the benefit between the age groups (P = 0.25).'] Does lymph node involvement in colon cancer patients decrease with age ; a population based analysis?
