<qa>  What is the common use of radical surgery in many instances?In this study, we intend to explore the feasibility and the effects of adding bevacizumab to Fl-TX in patients with intermediate stage head and neck cancer and selected patients with stage IV disease. As mentioned previously, although single modality therapy surgery or radiotherapy alone is often used to treat patients with Stage II head and neck malignancies, with substantial success, still there is a sizeable group of patients approximately 30 or 40 who fail these treatments, and represent with locoregional recurrences which are much more difficult to treat. Furthermore, the common use of radical surgery in many instances leads to loss of organ function.
