R-CHOEP14 in younger high-risk patients with large B cell lymphoma: an effective front-line regimen with cardiac toxicity: a real-life, single-center experience

Currently, there is no consensus regarding optimal front-line treatment for younger high- risk patients with large B cell lymphoma. American recommendations list only R-CHOP as standard, while European also include R-ACVBP and R-CHOEP14. We have been routinely using the latter regimen at our institution since 2011 and performed this retrospective real-life single-center study to analyze outcomes. Between September 2011 and April 2019, 66 newly diagnosed patients aged 18 to 60 years with B- large cell lymphoma and high-risk age-adjusted International Prognostic Index score were scheduled to receive 6 or 8 cycles of bi- weekly chemoimmunotherapy with cyclophosphamide, doxorubicin, vincristine, etoposide, steroids, and rituximab (R-CHOEP14). After a median follow-up of 4.7 years, the estimated 3-year progression-free survival was 87% (95% CI 80- 96%) and 3-year overall survival 90% (95% CI 83-98%). Grade ≥ 3 hematological side effects occurred in 83% and infectious in 41% of patients ; one patient died of toxicity. Grade ≥ 2 cardiac toxicity occurred in 21% of patients, more frequently than previously reported. The cumulative 5-year risk of congestive heart failure with all-cause mortality as the competing risk was 17%. R-CHOEP14 is a very effective and manageable regimen for younger high- risk patients with B-large cell lymphoma, but the risk of cardiotoxicity warrants further investigations.
