Abstract

One hundred thirty-six surgical cases of squamous cell carcinoma of the oral tongue and floor of the mouth at the Emory University Hospitals were reviewed for the incidence of occult metastases. Thirty-five percent of the T1 T2 lesions of the anterior tongue had occult metastases. The figure was 31.5% for similarly staged lesions of the floor of the mouth. The presence of regional metastases resulted in a 2-year determinate survival rate of 37% and 32% for patients with oral tongue and floor of the mouth lesions, respectively. The poor prognosis in the study for delayed cervical metastases and the high incidence of occult cervical metastases have led the authors to propose a more aggressive therapy for the clinically negative necks in these two sites of squamous cell carcinoma of the oral cavity.
