Abstract

PURPOSE: CD137 molecule is expressed by activated lymphocytes, and in cancer patients identifies the tumor-reactive Tcells. In solid tumors, high levels of circulating CD137

EXPERIMENTAL DESIGN: PBMC derived from 109 metastatic cancer patients (66 patients for the identification cohort and 43 for the validation cohort) were analysed for the expression of CD3,CD4,CD8,CD137 and PD1 molecules before the beginning of anti-PD1 therapy. Twenty-healthy donors were used as control. The soluble form of CD137(sCD137) was also analysed. The CD137

RESULTS: The percentage of CD137

CONCLUSIONS: We propose the CD137
