Interestingly, Weidhaas et al. recently performed a secondary analysis of a randomized phase III HNSCC trial and found that patients with an oncogenic germline KRAS variant (a let-7 microRNA-binding site polymorphism in the 3’ untranslated region of KRAS) have significantly better clinical outcomes with cetuximab (EGFR monoclonal antibody) addition to radiotherapy plus cisplatin regimen58. Here, EGFR is linked to head and neck squamous cell carcinoma.
