Abstract
Autologous hematopoietic stem cell transplantation (auto-HSCT) has improved survival in patients with multiple myeloma (MM) and is increasingly used in elderly patients. The aim of this study was to characterize and compare in-hospital complications and mortality after auto-HSCT in younger (< age 65) vs. elderly (≥ age 65) MM patients utilizing the Nationwide Inpatient Sample (NIS). Over a three-year period (2008-2010), 2209 patients with MM were admitted to U.S. Hospitals for auto-HSCT. The median age was 59 years, with 1650 patients (74.7%) younger than age 65 and 559 patients (25.3%) age 65 or older. Overall, in-hospital mortality in MM patients following auto-HSCT was rare (1.5%) and there was no significant difference in mortality between elderly and younger patients. Elderly patients did have a significantly increased mean length of stay (18.6 days + 10.8 days (standard deviation) vs. 16.8 days + 7.2 days, p<0.001) and mean total hospital charges ($161,117 + $105,008 vs. $151,192 + $78,342, p=0.018) compared to younger pts. Elderly patients were significantly more likely than younger patients to develop major in-hospital post-transplant complications such as severe sepsis (OR 2.70, 95% CI: 1.40-5.21, p=0.003), septic shock, (OR 3.10, 95% CI: 1.43-6.71, p=0.004), pneumonia (OR 1.62, 95% CI: 1.06-2.46, p=0.024), acute respiratory failure (OR 3.44, 95% CI: 1.70-6.96, p=0.001), endotracheal intubation requiring prolonged mechanical ventilation (OR 2.19, 95% CI: 1.06-4.55, p=0.035), acute renal failure (OR 2.14, 95% CI: 1.38-3.33, p=0.001), and cardiac arrhythmias (OR 2.06, 95% CI: 1.52-2.79, <0.001). This data may help guide informed consent discussions and provide a focus for future studies to reduce treatment-related morbidity in elderly MM patients undergoing auto-HSCT.
