AYA-Myeloma: Real-World, Single-Center Experience Over Last 5 Years

Multiple myeloma (MM) is considered as a disease of the old with the reported median age of 60-70 years. The disease occurred a decade earlier in the Indian subcontinent. The literature on MM in adolescents and young adult (AYA) is limited. We studied the disease characteristics and outcomes of the AYA-MM in the real-world setting.

It is a retrospective single-center study conducted at a tertiary care center from North India. Records of all consecutive patients with AYA-MM (15-39 years of age) who were managed from January 1, 2010, to December 30, 2015, were reviewed. Survival was assessed from the date of start of treatment to the last follow-up date or death due to any cause.

A total of 415 patients managed for MM were included in the study. The frequency of the AYA-MM was 9.6% (40/415) of whom 5 patients were younger than 30 years. There was male preponderance with a median age of the patients being 38 years. The main presenting features were bone pain (55%), fatigue (45%), extramedullary plasmacytomas (20%), and infections (12%) and referral from the peripheral hospital as renal dysfunction (58%). On the evaluation of patients, hypercalcemia, renal impairment, anemia, and lytic lesions were seen in 24.32%, 30%, 52.5%, and 59.25% of patients, respectively. The majority had the high-risk disease (International Staging System [ISS]-III: 75%). Only 22.5% patients were transplanted. The 3-year median overall survival of the study population was 80.21%.

AYA-MM patients have a higher prevalence of extramedullary disease and high-risk disease.
