Relation of thickness of floor of mouth stage I and II cancers to regional metastasis

Am J Surg. 1986 Oct;152(4):351-3. doi: 10.1016/0002-9610(86)90303-x.


We have reviewed the clinical course and histologic findings in 84 patients with stage I and II squamous carcinoma of the mouth floor. We concluded that lesion thickness may offer a useful method for predicting the probability of cervical metastasis in node negative (N0) patients. Moreover, surface area of the lesion did not correlate with subsequent nodal disease, whereas thickness did. Elective node dissection appears to be strongly indicated in any patient with a N0 lesion measuring more than 1.5 mm in thickness.
