Objective:

Multiple myeloma in Colombia is the one of the main reasons for autologous hematopoietic stem cell transplantation (HSCT). The aim of this study is to describe the results of the HSCT in adult patients diagnosed with multiple myeloma in the Fundación Valle del Lili. Materials and methods: An observational, descriptive study of a retrospective cohort was carried out. Patients older than 18 years with a diagnosis of multiple myeloma with autologous HSCT between 2008 and 2016 were included. The outcomes were overall survival, progression-free survival, and post-transplant disease response. A descriptive statistical analysis was carried out for all the variables considered in the analysis. The survival analysis was performed using the Kaplan-Meier method.

Results:

During the study period, transplants were performed on 103 patients with a diagnosis of multiple myeloma. The median age was 57 years. The subtype of secreted immunoglobulin was 75% IgG, 18% IgA, 5% non-secretor, and 2% oligo-secretor. The majority of patients were in Durie Salmon stage was IIIA (43.7%). Prior to transplantation 31% had a very good partial response, 25.2% complete response, 19.4% partial response, 10.7% progressive disease, 6.8% stable disease, 2.9% complete strict response, and in 3.9% of the patients the report of the disease status was not found. The 5-year overall survival was 71% (95% CI: 53-83) and progression-free survival was 40% (95% CI 25-54). After transplantation 33% of the patients were in very good partial response, 25% in strict complete response, 22% in complete response, 12% partial response, and 8% progressive disease or relapse.

Conclusion:

Autologous HSCT is a strategy that is associated with good survival rates, low toxicity, and an adequate post-transplant disease response.
