R-CVP regimen is active in frail elderly patients aged 80 or over with diffuse large B cell lymphoma

Patients aged 80 or over with diffuse large B cell lymphoma (DLBCL) often have comorbidities that increase drug toxicity and prevent the use of otherwise optimal treatment. We performed a retrospective analysis of 43 patients aged 80 or over (median age: 83; range: 80–93) unable to receive treatment with anthracyclines, at diagnosis of DLBCL, treated with an R-CVP treatment (standard R-CHOP without doxorubicin). The patients had one or more comorbidities: 18 patients (41.9 %) had a performance status (PS) of 3; 23 patients (53.5 %) had low creatinine clearance; 12 patients (27.9 %) had low left ventricular ejection fraction; seven patients (16.3 %) had poor hepatic function; and 26 patients (60.5 %) had a Charlson index score ≥4. Thirty patients (70 %) had two or three adverse factors according to the age-adjusted International Prognostic Index. Twenty-five patients (58.1 %) received eight cycles of R-CVP, but the full eight cycles could not be given to 18 patients (41.9 %). The OR rate was 58.1 % (CR 37.2 %). There were 34 deaths (79 %) during treatment and follow-up. Ten patients (23.3 %) died early from toxicity before interim evaluation; all had PS 3. The median follow-up of surviving patients was 52.6 months. The overall 2-year survival rate was 31.9 % and the median OS was 12.6 months. The median OS for patients who completed the entire treatment was 26.4 months. The median PFS was 11.2 months. In multivariate analyses, OS was only affected by performance status ≥2 and Charlson index score ≥4. The R-CVP regimen can be active in elderly frail patients aged 80 or more with DLBCL, but systematic geriatric assessment is required so that those unsuitable for chemotherapy are excluded.
