Objective: There is no established therapy for recurrent/metastatic head and neck squamous cell carcinoma (HNSCC), making decisions regarding anticancer agent use and other treatments difficult. Cetuximab, an anticancer drug used as molecular targeted therapy, is administered irrespective of patient sensitivity due to unavailability of biomarkers predicting its efficacy. We investigated the utility of antitumor effect prediction of cetuximab using collagen gel droplet-embedded culture drug sensitivity test (CD-DST).
Methods: We evaluated 13 human oral squamous carcinoma cell lines (Ca9-22, SAS, SAT, HSC-2, HSC-3, HSC-4, OSC-19, OSC-20, HO-1-N-1, HO-1-u-1, KON, SCC-4, and Nialym). The expression of cetuximab-related genes was confirmed in each cancer cell line using RT-PCR, and CD-DST was used to measure cell line sensitivity to cetuximab and to.. View More»
