Question 62 · LDEK · Malignant tumors
Indicate the true statements concerning lip cancer:
1) treatment consists in freezing the lesion if it is less than 2 cm, or in lip excision, if the lesion involves more than a half of the lip and the stage is T1;
2) treatment consists in the V excision with a reconstruction or brachytherapy if the lesion does not infiltrate and is < 0,5 cm in size and the stage is T1;
3) location of the cancer in the angle of the mouth, just as infiltration of the angle of the mandible, is a contraindication to brachytherapy and/or teletherapy,
4) metastases of lip cancer occur in 10% of patients, and that is why elective lymph node resection is not performed;
5) lip cancer is usually a squamous cell carcinoma of medium (G2) or low (G3) differentiation grade.
