Abstract :

Richterâ??s transformation (RT, Richterâ??s syndrome) was first described by Maurice Richter as the development of an aggressive large-cell lymphoma in the setting of underlying small lymphocytic lymphoma /chronic lymphocytic leukemia (SLL/CLL). We try to investigate the role of in detection of RT of SLL/CLL. Twelve patients with SLL/CLL underwent 18F-FDG PET/CT between Jul 2010 and Nov 2015 were retrospectively analyzed. FDG avid lesions with a maximum standardized uptake value (SUVmax) of greater than 5 were considered highly suggestive of RT. The diagnosis of RT was based on the histopathological examination. All patients (8 males and 4 females) had the history of SLL/CLL ranged from 2 years to 11 years. Four patients underwent RT to diffuse large B-cell lymphoma, PET/CT detected sites of increased FDG uptake with SUVmax ï¼?5 in 3 patients(3/4, 75%), 1 patient has false-negative PET/CT findings. No patient had false-positive PET/CT findings and PET/CT correctly excluded RT in the other 8 patients. The overall sensitivity, specificity and accuracy of PET/CT for RT of SLL/CLL were 75%, 100% and 91.6%, respectively. According to the preliminary data, 18F-FDG PET/CT has high accuracy for detection of RT of SLL/CLL. PET/CT can exclude the diagnosis of RT with a high degree of confidence in patients with SLL/CLL.
