Abstract
- Doxorubicin is an effective agent for many malignancies. To limit cardiotoxicity, doxorubicin can be given as prolonged infusion (PIDX) or bolus infusion following dexrazoxane (DZX). The authors report their institutional experience comparing PIDX and DZX in a sarcoma cohort. Retrospective record review for newly diagnosed sarcoma patients at the University of Texas M.D. Anderson Cancer Center from June 1998 to June 2006. There were 23 Ewing's sarcoma (EWS) patients treated with DZX and 40 osteosarcoma (OS) patients treated with PIDX. The DZX group had higher mean cumulative anthracycline dose (510 mg/m(2) [SD 120 mg/m(2)] versus 414 mg/m(2) [SD 99 mg/m(2)], P = .002), however mean lowest left ventricular ejection fraction (EF) values were higher for DZX (52.5% [SD 5.6%] versus 47.2% [SD 10.9%], P = .014). Fifteen of 19 patients with cardiac dysfunction were PIDX patients (P = .15). Five PIDX patients required cardiac medication, and 1 patient died of congestive heart failure (CHF). Sixteen patients with cardiac dysfunction had improvement, demonstrated by EF ≥ 50% at last echocardiogram. Although not statistically significant, there were 4 DZX patients with cardiac dysfunction. Prospective studies are required to determine which strategy has long-term advantages and if certain patients are at increased risk for cardiac dysfunction.
