BACKGROUND: Racial differences in follicular lymphoma (FL) in the United States have not been investigated. METHODS: The National LymphoCare Study is a multicenter, longitudinal, observational cohort study collecting data on treatment patterns and outcomes for patients with newly diagnosed FL in the United States between 2004 and 2007 without any predefined, study‐specific intervention. The authors investigated differences between white (W) patients, African American (AA) patients, and Hispanic (H) patients. RESULTS: Among 2744 enrolled patients, there were 95 (3%) AA patients, 125 (5%) H patients, and 2476 (90%) W patients. Compared with W patients, more AA and H patients were diagnosed at age <45 years ( P < .0001). H patients more commonly were diagnosed with grade 3 FL compared with AA and W patients (29%, 13%, and 18%, respectively; P = .019) and more commonly received rituximab plus chemotherapy as initial therapy compared with W patients (66% vs 50%; P = .036), while AA patients less commonly received anthracyclines (49% vs 64% in W patients; P = .027). H and AA patients who received rituximab plus chemotherapy were less likely than W patients to receive maintenance rituximab (27% vs 31% vs 40%, respectively; P = .031). At a median follow‐up of 52 months, progression‐free survival was similar between AA and W patients but was longer in H patients, and there was no difference in overall survival. CONCLUSIONS: In the largest prospective cohort to date of AA and H patients with FL in the United States, AA and H patients were younger at presentation. Although racial differences in treatment patterns for FL were noted, additional follow‐up is needed to determine the impact of these differences on survival.
