Baseline tumor samples were analyzed for the hypoxia marker carbonic anhydrase IX (CAIX) and tumor-infiltrating lymphocytes (TILs) and were correlated with [18F]-misonidazole ([18F]FMISO) PET measurements. The impact of the biomarkers on the locoregional control (LRC) was examined using Cox analyses and concordance index statistics.Low CAIX (HR=0.352, 95 %K Carbonic anhydrase IX (Other) %K FMISO PET (Other) %K Head-and-neck squamous cell carcinoma (Other) %K Hypoxia (Other) %K Radiotherapy biomarker (Other) %K Tumor-infiltrating lymphocytes (Other) %F PUB:(DE-HGF)16 %9 Journal Article %$ pmid:33753155 %R 10.1016/j.radonc.2021.03.014 %U https://inrepo02.dkfz.de/record/168136
