Abstract

Background: Although adjuvant chemotherapy in stage III colon cancer improves overall survival, prior studies have shown that it is underused. We analyzed different factors that may influence its use. Methods: This is a retrospective study of stage III colon cancer patients (n = 207,718) diagnosed between 2000 and 2011 in the National Cancer Data Base (NCDB). The NCDB contains ∼70% of new cancer diagnosis from >1500 American College of Surgeons accredited cancer programs in the United States and Puerto Rico. The chi-squared test was used to determine any difference in characteristics of patients who did or did not receive chemotherapy. Results: A total of 35% of all stage III colon cancer patients, and 38% of stage III cases undergoing surgery, did not receive adjuvant chemotherapy. The use of chemotherapy had increased in recent years (64% in 2007-2011 versus 59% in 2000-2002; p <0.0001). Its use was lower in whites (61%), females (60%), patients ≥3/460 years (55%), patients with one or more comorbidities (55%), nonacademic centers (62%), those with medicare insurance (52%), lower education (61%) and income levels (59%, all p <0.0001). The nonwhite and uninsured were more likely to be
