Hematology-oncology provider perspectives regarding lymphoma treatment and cardioprotective strategies in patients with lymphoma at high risk for heart failure

The optimal treatment of patients with diffuse large B-cell lymphoma (DLBCL) or Hodgkin lymphoma (HL) with preexisting cardiomyopathy is uncertain. An anonymous, electronic survey was distributed by e-mail to three US lymphoma cooperative groups, two community hospitals, and twelve academic medical systems, and distributed at one international lymphoma meeting. Fifty hematology-oncology providers caring for patients with lymphoma were included. In response to a vignette of a 67-yo with Stage III DLBCL with LVEF of 40-45%, 15 (30%) would use non-anthracycline regimens, 13 (26%) R-CHOP with liposomal doxorubicin instead of doxorubicin, 11 (22%) R-CHOP without modification and 6 (12%) R-CHOP with a continuous doxorubicin infusion. In a second vignette of a patient with HL in remission after frontline treatment with doxorubicin cumulative dose 300 mg/m², 16 (32%) would order an echocardiogram after treatment. There was substantial variability in preferred treatment regimens with preexisting cardiomyopathy and in cardiac monitoring after anthracycline.
