In all, 171 patients (20%) were stage I, 375 (43.8%) were stage II and 311 (36.3%) were stage III. Over 95% of all patients underwent surgery regardless of age or diagnosis year. In stage III colon cancer the proportion of patients who received adjuvant treatment increased the more recent the year of diagnosis (1994–2000, 47%; 2001–2005, 66%; 2006–2010, 70%; <italic>P</italic> = 0.017). According to analysis by age group, older patients were less likely to receive adjuvant chemotherapy in both stage II (more than 75 years, 47.3%; 70–74 years, 59.4%; <italic>P</italic> < 0.001) and stage III (more than 75 years, 51.1%; 70–74 years, 76.7%; <italic>P</italic> < 0.001).
