Abstract:
OBJECTIVETo analyze the pathological type and clinical features of patients with lymphoma cell leukemia (LML).
METHODSAccording to the 2008 WHO classification of tumors of hematopoietic and lymphoid tissue, the pathological type and clinical features of 127 LML cases were analyzed retrospectively.
RESULTSThere were 15 kinds of NHL developed LML. The incidence in frequent order of them was B-lymphoblastic lymphoma, CLL/small lymphocytic lymphoma (SLL) and T-lymphoblastic lymphoma. The LML of T and B cell subtypes were 45 and 74, respectively. There was a significant difference in overall survival between T-LML and B-LML (P < 0.01). Eighty one patients presented LML at the same time of the NHL diagnosis and 46 during the course (1 - 88 months) of disease. Primary nodal and extranodal NHLs developed LML were 96 and 31 cases, respectively. The clinical manifestations of LBL and SLL patients differed from that of ALL and CLL patients.
CONCLUSIONLML is not a rare manifestation of NHL. Pathological types of NHL developed LML are 15 kinds in our patients. The clinical features of LML patients are somewhat special, especially for primary extranodal LML patients.
