Between January 17, 2019, and November 29, 2021, 74 patients were enrolled in this study. In 4 patients (5%), an infusion-related adverse event led to the termination of intravenous administration. All these adverse events occurred during the administration of unlabeled cetuximab (see ‘Safety data’). Four other patients could not be included in the final analyses since all tumor tissue was removed during diagnostic biopsy without this being clinically evident. In one patient, all images had to be excluded (see “Methods”). In the remaining study population of 65 patients, we analyzed 66 tumor specimens since one patient presented with two separate primary tumors on both sides of the tongue. The median age of patients was 68 years (range 29–90) and 33 were female (51%). Primary tumors were located in the tongue (Patient and specimen characteristicsTongueMandibular gingivaMaxillar gingivaFloor of mouthCheekBuccal foldGlossotonsillar sulcus30 (45)20 (30)6 (9)5 (7)4 (6)1 (1)1 (1)T1T2T3T424 (36)22 (33)4 (6)17 (25)Data are presented as median (range) or
