PVR and neoplasm: Univariate Cox proportional Hazard regression analysis for all variables showed that tumor volume, tumor stage, depth of tumor infiltration, lymph node involvement, distant metastasis, CD155, CD4, CD8, IFN-γ, CD19, α-SMA, as well as CD155 and TME molecules co-expression patterns for CD155/CD3, CD155/CD4, CD155/CD8, CD155/IL-17, CD155/IFN-γ, CD155/CD19, and CD155/α-SMA were factors affecting postoperative survival in GAC patients (Table 3).
