Connection between PD-L1 expression and standardized uptake value in NSCLC: an early prognostic treatment combination.

Objectives Lung cancer is still diagnosed at advanced stage and early treatment initiation is needed. Therefore, we need biomarkers or clusters of information that can provide early treatment prognosis. Methods Biopsies were acquired from 471 patients-lung masses with CT-guided biopsy, convex probe transthorasic biopsy and EBUS-TBNA convex probe with 18G needles and 19G needles. Results Standardized uptake value (SUV) measurement is associated with female, smoking status, hepatic metastasis, adenocarcinoma and programmed death-ligand 1 (PD-L1). In specific we expect that SUV ≥ 7 is associated with PD-L1 ≥ 50. Conclusions Lung masses indifferent of size that have SUV ≥ 7 will also have PD-L1 expression ≥ 50. Also, it is likely that these patients will be female with intense smoking habit and hepar or multiple metastasis.
