ENTPD1 and neoplasm: Further analysis identified a novel MDSCs subpopulation enriched in CD39 and CD73 in tumor lesions of NSCLC patients defined as Lin−CD14−CD11b+CD39+CD73+ and Lin−CD14+CD11b+CD39+CD73+ that were found to be positively correlated to disease progression and were reduced after chemotherapy cycles suggesting them as predictive tools for chemotherapy response (254).
