“…Head and neck cancer is classified into the following categories: early-stage or stage I/II, locally advanced or stage III/IV, and recurrent or metastatic phase [ 67 ]. Early stages of head and neck cancer are usually treated with a single-modality treatment, such as radiotherapy or surgical resection [ 4 , 12 , 13 , 15 , 68 ]. A combination of multiple therapies for superior oncologic results are required for the management of advanced stages III/IV [ 4 , 61 , 67 ]; for example, surgery with adjuvant radiation or chemoradiation with chemotherapy being added for high risk pathologic features found from the surgical specimen [ 2 , 14 , 35 , 69 , 70 ], or radiotherapy with concomitant chemotherapy [ 14 , 64 , 71 , 72 , 73 ].…”
