Introduction: The adolescent and young adult (AYA) age group (15-39 years) bears distinct characteristics in terms of cancer biology, long-term health and treatment-related complications and psychosocial aspects. The overall scenario of cancer including hematological malignancies (HMs) is largely unknown in Bangladesh, where a significant proportion of people (44% of total population) belong to AYA age group. This study aims to describe the patterns of HM among AYA in the context of Bangladesh METHODS: Two previously published datasets (on hematological malignancies and childhood and adolescent cancer) were merged to construct a comprehensive dataset focusing exclusively on HMs in AYA age group. Univariate descriptive statistics were calculated and bivariate association were tested using Pearson's Chi-square test.
Results: A total of 2144 diagnosed HM related cases over a period of 2007-2014 were analyzed. Acute myeloid leukemia (AML) was the most frequent HM (35.1%) in AYAs, which was followed by acute lymphoblastic leukemia (ALL) and chronic myeloid leukemia (CML) constituting 22.7% and 20.8%, respectively. Among lymphomas, Non-Hodgkin lymphoma (NHL) constituted 13.9% of all HMs while 4.6% was for Hodgkin's lymphoma (HL).
Conclusion: This is the first attempt to provide a glimpse on the pattern and distribution of HMs among AYA in Bangladesh. Future studies are essential to get a better insight on the epidemiology, biology, potential risk factors and treatment outcomes for the AYA age group.
