Abstract:
Objective To analyze the diagnosis and therapy for double-hit lymphoma (DHL) and triple-hit lymphoma (THL).
Methods This study involves three patients with follicular lymphoma (FL) that transformed into DHL or THL. These patients were admitted to our hospital between January 2011 and December 2012. All patients were diagnosed by immunohistochemistry and fluorescence in situ hybridization (FISH).
Results One FL patient transformed into THL and died after 3 months. The other two FL patients who transformed into DHL and who received R-CHOP and R-ESHAP regimens still failed to achieve complete remission.
Conclusions DHL is a rare type of lymphoma that usually involves the bone marrow and central nervous system. This condition is highly resistant to intensive chemotherapy. Part of the DHL cases result from FL. FISH is important for diagnosis. However, a standard treatment for this type of lymphoma remains lacking.
