Acute leukemia patients with any comorbidity and lymphoma patients with higher lactate dehydrogenase and beta-2-microglobulin are at high risk of developing thromboembolic complications.
Therefore, this study aimed to determine the clinicopathological relevance of HLA and β2M expressions in ATLL cells and PD-L1 expression in lymphoma or stromal cells and predict the overall survival of patients with ATLL.
