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 KW - Carbonic anhydrase IX (Other) KW - FMISO PET (Other) KW - Head-and-neck squamous cell carcinoma (Other) KW - Hypoxia (Other) KW - Radiotherapy biomarker (Other) KW - Tumor-infiltrating lymphocytes (Other) LB - PUB:(DE-HGF)16 C6 - pmid:33753155 DO - DOI:10.1016/j.radonc.2021.03.014 UR - https://inrepo02.dkfz.de/record/168136 ER -
