Progress of double hit lymphoma and double expression lymphoma / 白血病·淋巴瘤

ABSTRACT

In 2016, the World Health Organization redefined double hit lymphoma and double expression lymphoma as high-grade lymphoma, a group lymphoma characterized by aggressive disease and poor prognosis. Double hit lymphoma and double expression lymphoma are related to the abnormal expressions of c-myc, bcl-2 and bcl-6 genes. Because of the differences in disease progression and prognosis of both lymphomas, R-CHOP is less effective in treating them. The adjusted R-Hyper-CVAD, R-CODOX-M/IVAC and R-EPOCH regimens have shown good results, but targeted therapy may be the most effective regimen due to their specific genetic abnormalities. This article will review its clinical characteristics, pathogenesis, diagnosis and treatment of double hit lymphoma and double expression lymphoma.
