CD274 and cervical cancer: Regarding the differences (Figure 8) in the non-metastatic regional lymph nodes between the different primaries (Fisher test), vulvar cancer-draining lymph nodes showed higher PD-L1 values than endometrial cancer-draining and cervical cancer-draining lymph nodes (9 ± 10.748 for vulva, 1.512 ± 3.333 for endometrial, and 0 for cervical, p = 0.0004 and 0.039, respectively).
