This study hypothesised a high expression of CD68+, CD163+ TAMs and PD-L1 would lead to worse survival in OSCC patients, whereas concluded that CD163+ TAMs located in both tumour and stroma were predictive of a poor prognosis in OSCC and that PD-L1 may prove to be indicative of a positive outcome in these patients. Here, CD163 is linked to neoplasm.
