Diffuse large B‐cell lymphoma (DLBCL) is the most common lymphoma entity, and its incidence increases with age. There is a paucity of data regarding use of biweekly R‐CHOP (R‐CHOP‐14) in patients ≥80 years of age. We performed a retrospective cohort study of patients with DLBCL aged ≥80 years treated with R‐CHOP‐14 and R‐miniCHOP in two academic tertiary centers in Germany between 01/01/2005 and 12/30/2019. Overall, 79 patients were included. Median age was 84 years (range 80–91). Despite higher CR rates with R‐CHOP‐14 (71.4% vs. 52.4%), no statistically significant difference could be found between patients treated with R‐CHOP‐14 and R‐miniCHOP regarding overall survival (OS) (p =.88, HR 0.94, 95% CI = 0.47–1.90) and progression‐free survival (PFS) (p =.26, HR 0.66, 95% CI = 0.32–1.36). At a median follow‐up of 40 months, the 2‐year OS rates were 56% with R‐CHOP‐14 and 53% with R‐miniCHOP. Two‐year PFS rates were 46% for R‐CHOP‐14 and 50% for R‐mini‐CHOP. Relative dose intensity of chemotherapy did not correlate with OS (p =.72). With the caveat of a retrospective cohort study, we conclude that lacking a difference in OS, R‐miniCHOP should be preferred for most patients with untreated DLBCL aged ≥80 years.
