Similar to PD-L1-expressing myeloid cells and sPD-L1, we found clinicopathologic-independent accumulation of both PD-L1+TC and PD-L1+IC, except higher expression of PD-L1+TC but not PD-L1+IC in the endometrioid versus mucinous type of tumours, which is in accordance with meta-analysis of Wang et al. where showed that PD-L1 protein expression was not associated with clinical features of OC (i.e. grade, stage or lymph node status) [45]. This evidence concerns the gene SPDL1 and neoplasm.
