Multiple myeloma: Experience of an institute in limited resource setting

Multiple myeloma (MM) is a plasma cell dyscrasias and an incurable clonal B-cell malignancy, with an annual incidence of 1% of all malignancies. The mainstay of treatment of myeloma is induction treatment followed by consolidation with autologous stem cell transplant (ASCT). However, still in a developing country like India where affordability is a major hurdle for health care, a number of MM patients are not able to undergo ASCT.

To study the epidemiological features and outcome of MM patients treated in a limited resource setting.

We conducted a retrospective study at our institute to identify patients diagnosed as MM from 2005 to 2016. We studied the epidemiological profile and the outcome of the treatment in terms of response rates and overall survival.

Survival analysis was performed using Kaplan-Meier curve.

Median age at diagnosis is 54 years (range: 39-85 years). IgG myeloma was the most common type seen in 72% of patients. The International Staging System (ISS) was ISS I (31%), ISS II (30%), and ISS III (39%). The median duration of treatment for thalidomide + dexamethasone (TD) and bortezomib + TD (VTD) was 9 and 7 months, respectively. Median survival for the TD versus VTD regimen (in a nontransplant setting) for the ISS I, ISS II, and ISS III groups was 49 and 55 months (P = 0.056), 42 and 48 months (P < 0.05), 21 and 27 months (P < 0.05), respectively.

Proteasome inhibitors significantly improved the median survival for patients with MM (ISS II and ISS III) treated in a limited resource setting.
