CD274 and neoplasm: In this study, lymph node status was also not related to PDL-1 Expression in either (T) and (TILs) but Droeser et al., (2013) concluded that there was statistical relation between expression of PDL-1 in tumor cells and absence of lymph node metastasis (p value 0.015), however, Lee et al., (2016), Rosenbaum et al., (2016), Masugi et al., (2016) and Zhong et al., (2018) supported our results (p value=0.067, 0.32, 0.14 and 0.261) respectively and also Valentini (2018) with no available p value figure.
