CDKN2A and neoplasm: Strikingly, we observed that both the overall abundance of CTL (r: 0.358, p <0.001) and their infiltration into the tumor compartment (r: 0.339, p=0.001, see Supplementary Table 6) were significantly associated with p16 tumor positivity, whereas other clinical parameters such as smoking status or alcohol consumption were not associated with CTL infiltration.
