Follicular Lymphoma in Young Adults: Study from a Regional Cancer Center in South India.

ABSTRACT

Objective Follicular lymphoma (FL) is a disease of the elderly. It is postulated that younger patients have distinct tumor biology and treatment outcomes. Various lymphoma groups across the world have studied this to understand if young adults (YAs) need a different treatment approach. Our study fills the void in data from an Asian country on YA population with FL. Patients and Methods We retrospectively analyzed young patients (age ≤40 years) diagnosed with FL at our center from 2012 to 2018. Their disease characteristics, treatment details, and outcomes were studied to examine any association between various parameters and survival. Results There were 28 young FL patients included in our study that constituted 14.6% of FL cases (males 53.5% and females 46.5%). The median age at diagnosis was 36.5 years. Most of the patients presented in an advanced stage, 57% had extranodal involvement, and 39.3% had bone marrow involvement at the time of presentation. The most common chemotherapy regimen used was cyclophosphamide, vincristine, and prednisone. Half of them received chemoimmunotherapy and only 18% continued rituximab as maintenance therapy. The overall response rate was 92.9% ( n = 26), and the remaining two patients had progressive disease while on treatment. The median progression free survival (PFS) was 6.1 years and median overall survival (OS) was not reached. On univariate analysis, extranodal disease was associated with a lower PFS ( p = 0.06) and low hemoglobin showed a significant association with OS ( p = 0.005). On multivariate analysis, none of the factors showed a significant association with survival. Conclusion Most YAs present with advanced disease with a good response to treatment and favorable outcomes.
