“…Next-generation sequencing identified recurrent subtype-unique mutations including: APC , CTNNB1 , PIK3CA and KRAS in ITAC, EGFR and CDKN2A in SNSCC, NRAS and NF1 in MMM, IDH2 in SNUC, and ARID1A , SMARCB1 and SMARCA4 in SNEC, SNUC and TCS [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. Other markers such as Somatostatin receptor 2 (SSTR2) expression were also reported in sinonasal cancers, such as in ONB [ 27 ]. Moreover, genetically well-characterized stable tumor cell lines, organoids and animal models are becoming available for the preclinical testing of candidate therapeutic agents [ 28 , 29 , 30 , 31 , 32 ].…”
