Intra-arterial chemoradiation for T3-4 oral cavity cancer: treatment outcomes in comparison to oropharyngeal and hypopharyngeal carcinoma.
BACKGROUND
Surgery followed by radiotherapy is the standard of care for resectable locally advanced oral cavity squamous cell carcinoma (SCC). We report the treatment outcomes of patients with T3-T4 SCC of the oral cavity treated with chemoradiation, an alternative approach.


METHODS
From a series of 240 patients with stage III-IV carcinoma of the upper aerodigestive tract who were treated consecutively according to the RADPLAT protocol, a subset analysis of 155 patients with T3-T4 SCC (Oral cavity SCC N = 22, oropharynx SCC N = 94 and hypopharynx SCC N = 39), was performed. The goal was to test the hypothesis that oral cavity SCC treated with chemoradiation has similar outcomes to the two comparison sites.


RESULTS
With a median follow-up of 58 months, local disease control was 69% and the overall survival was 37%. In comparison, local disease control for the oropharynx and hypopharynx groups was 86% and 79% respectively. The overall survival rate for the oropharyngeal and hypopharyngeal groups were 41% and 6% respectively


CONCLUSIONS
Patients with locally advanced oral cavity cancer treated with the chemoradiation protocol RADPLAT have outcomes that are equal or better compared to patients with similar disease involving the oropharynx and hypopharynx.
