Multiple primary tumours in oral cancer. 1986

N de Vries, and I Van der Waal, and G B Snow

In 210 cases of oral cancer, 38 (17.6%) second primary tumours were found. Males had a higher chance of developing a second primary than females (21.4% versus 12%). The difference was not statistically significant (p = 0.11). When the index tumour was in the lower part of the oral cavity (floor of mouth, retromolar trigone, inferior alveolar process), a higher rate of second primaries was found than in cancer of the rest of the oral cavity (tongue, buccal mucosa and palate) (26.6% versus 11.5%). In male patients, this difference was statistically significant (p less than 0.05). 4 tumours were synchronous. In those 4 patients, panendoscopy would not have contributed to an earlier diagnosis. Routine panendoscopy in oral cancer therefore seems not valid.

D009061	Mouth Mucosa	Lining of the ORAL CAVITY, including mucosa on the GUMS; the PALATE; the LIP; the CHEEK; floor of the mouth; and other structures. The mucosa is generally a nonkeratinized stratified squamous EPITHELIUM covering muscle, bone, or glands but can show varying degree of keratinization at specific locations.
