Increased salivary level of defensin-1 [74], cancer antigen CA15-3 [5, 75], tumor marker proteins, like c-erbB-2 [5, 75] or CA-125 [76] and antibodies against the tumor suppressor protein, p53 [77] seem to be promising markers for both oral and other malignancies [2]. This evidence concerns the gene TCHP and neoplasm.
