Abstract
We aimed to evaluate the impact of concurrent chemoradiotherapy (CCRT) on the survival of patients with squamous cell carcinoma of the temporal bone. We retrospectively analyzed the data of 13 consecutive patients who were treated by definitive radiation therapy (RT) or CCRT as the initial treatment between 1999 and 2012. There were 5 patients with stage II disease, 5 with stage III, and 3 with stage IV, as classified according to the University of Pittsburgh system. Among these, 2, 4, and 3 patients, respectively, were treated by CCRT; whereas the remaining (3 patients with stage II and 1 with stage III) were treated by RT alone. Median follow-up duration was 39 months (12–106 months) in all cases, and 61.5 months (17–70 months) in censored cases. The 5-year overall survival (OS) rates were 51 % in all patients, and 40, 100, and 0 % in patients with stage II, stage III, and stage IV disease, respectively. In patients with stage II and III disease, the 5-year OS rates were 80 % in the CCRT group and 50 % in the RT-alone group. We found better prognosis in patients with stage II and III disease who were treated by CCRT. Only 2 patients treated by CCRT experienced adverse events more than grade 3, which were neutropenia and dermatitis. There was no late adverse event of bony necrosis. Our study results indicate that CCRT is safe and very effective as a first-line treatment for stage II and III squamous cell carcinoma of the temporal bone.
