Upon comparing these results with those of the survival analysis, we discovered a significant association between ITGAL and four prognostic factors, namely OS, DSS, DFS, and PFS, across eight types of tumors, including GBMLGG, LGG, KIPAN, UVM, CESC, LUAD, HNSCC, SKCM. Here, ITGAL is linked to head and neck squamous cell carcinoma.
