Modeling the contribution of synchronous chemotherapy to the rate of grade 3 and 4 mucositis in locally advanced squamous cell carcinoma of the head and neck

with local recurrence and the 13 patients who remain disease free were -7%,-62%, -50% and -16% comparedto -34%, -62%,-77% and -81%, respectively. Higher SUV were significantly associated with a higher risk of recurrence (p = 0.04). In contrast CT imaging demonstrated that primary tumor measurements at 2 weeks, 4 weeks, post RT 6 weeks, and 3 months steadily decreased in both groups with mean changes in the recurrence group and in the locally controlled group of -11%, -46%, -77%, and -100% and -47%, -57%, -73% and -99%, respectively. CT measurements were not associated with the risk of recurrence (p = .72).
