PDCD1 and neoplasm: Logistic regression analysis also demonstrated that PD-1+CD39+CD103+CD8+T (OR = 13.125, 95% CI: 1.876–268.997, p = 0.026) and PD-1+CD39+CD103-CD8+T (OR = 13.125, 95% CI: 1.876–268.997, p = 0.026) cells in tumor were both associated with high risk of tumor recurrence, despite no association found between these two CD8+T subsets and clinical parameters (Table S2).
