Multiple Myeloma in Young Adults: A Single Centre Real World Experience.

Multiple Myeloma accounts for 1% of all cancers. In India myeloma accounts for 1.23% of all cancers. The median age at diagnosis varies from 65 to 70 and only a small proportion of MMs are diagnosed at younger age, before 40 (approximately 2%). The present study is designed to analyse the clinical, haematological profile and outcomes in young adults with multiple myeloma. Data of all patients with age ≤ 40 years, diagnosed with multiple myeloma from 2013 to 2018 was analysed. A total of 258 patients were diagnosed with multiple myeloma between 2013 and 2018, of which 22 (8.5%) were aged ≤ 40 years. The median age was 33.5 years(range,18-40). Male to female ratio was 1.75:1. Bone pain (59%) and fatigue (45.4%) were the most common symptoms at presentation. Majority of patients were ISS stage 3(63.6%). Cytogenetic data was available only in seven patients and IgH translocation and del 13q were the most common abnormalities, seen in four and three patients respectively. Of 22 patients, 17 patients had at least one response evaluation and were evaluated for outcomes. Eleven patients (64.7%) had responses greater than VGPR. Six (41.6%) patients underwent Auto HSCT. Four patients received second line therapy and only two received further lines of therapy. At a median follow up of 18 months, 2-year EFS was 76.5% and 2-year OS was 94.1%. Patients younger than 40 years, constitute higher proportion of patients in Indian sub-continent. Renal failure was more common in young myeloma patients. Light chain myeloma was more common in young adults. Most patients were ISS stage 3 at presentation and survival seems to be better in young adults when compared to elderly patients.
