Survival rate of multiple myeloma patients in Indonesia: A retrospective study in multiple myeloma at a single institution

INTRODUCTION: To evaluate the response and the correlation between survival and prognostic factors in 32 patients with multiple myeloma. METHOD: We recruited 32 patients (18 men and 14 women) with mean age 59 years old who were diagnosed with multiple myeloma that were treated with surgery (n = 21) and without surgery (n = 11). 9 patients underwent hemiarthroplasty, 14 patients underwent open reduction and internal fixation and 4 patients underwent spinal decompression and posterior pedicular instrumentation from January 2012 to December 2017. In this group, there were 6 patients who underwent more than one surgeries. Patients were classified using the International Staging System (ISS) for multiple myeloma by evaluated albumin and β(2)-microglobulin level. RESULTS: The mean follow up period for 32 patients was 30.2 months (range, 3–65 months) with 7 patients in ISS stage I, 22 patients in ISS stage II and 3 patients in ISS stage III. The median survival duration was 28 months (95% CI). We documented the median survival for ISS stage II disease was 29 months, stage III disease 6 months and stage I disease 16 months with the median age of ISS stage I, II, and III disease was 65, 59, 60 years respectively. Survival correlation with ISS stage (p = 0.009), the hemoglobin level (p = 0.772), and the calcium level (p = 0.926). CONCLUSIONS: The survival rate was lower in patients with higher ISS stage for this disease. Survival rate seems to be better among younger patients than in older ones even with lower ISS stage of this disease.
