ABSTRACT
BACKGROUND:
The treatment of patients with multiple myeloma (MM) has evolved in recent years, and the disease-associated prognosis has improved substantially. This improvement has been driven largely by the approval of novel agents, many of which are expensive and not universally available. Less expensive but effective approaches would be of value globally. PATIENTS ANDMETHODS:
All consecutive MM patients diagnosed in the Centro de Hematología y Medicina Interna de Puebla after 1993 were included in this study. Patients were given oral thalidomide (100 mg/day), oral dexamethasone (36-40 mg/week), and aspirin 100 mg/day. Bor-tezomib (1.75 mg s.c. every week) was administered to those who could afford it. After 4-6 weeks of treatment, patients were offered an outpatient-based hematopoietic cell transplant (HCT). After the recovery of granulocytes following HCT, patients continued indefinitely on thalidomide; those who failed to tolerate thalidomide were switched to lenalidomide (25 mg/day).RESULTS:
The median overall survival (OS) for all patients has not been reached and is >157 months. Median follow-up of the patients lasted 14 months (range 1.3-157). The median OS of patients with and without HCT was similar. The response rate (complete remission or very good partial remission) was 72% for those given thalidomide plus dexamethasone versus 88% for those given bortezomib, thalidomide, and dexamethasone before HCT, but OS was not different. As post-HCT maintenance, 37 patients received thalidomide; 26 of those (70%) could be maintained indefinitely on thalidomide, whereas 11 were switched to lenalidomide after a median of 7 months; median OS of patients maintained on thalidomide or lenalidomide after HCT was not different.CONCLUSION:
In this series, a regimen incorporating low-cost novel agents and outpatient HCT was associated with excellent long-term survival in the treatment of MM patients. This approach may be a model for MM treatment in underprivileged circumstances.Palavras-chave
