Aytbaev E.S., Minenkov G.O. The treatment of the lower lip cancer
Objective. The study objective is to analyze the results of the X-ray, surgical and combined therapy of the lower lip cancer. Methods. The analysis of the therapy included 474 patients with lower lip cancer. 385 patients received X-ray therapy; 57 patients -surgical therapy; and 32 patients received combined therapy. Distribution of the observation of TNM: T<sub>1</sub>N<sub>0-1</sub>M<sub>0</sub> - 95, T<sub>2</sub>N<sub>0-3</sub>M<sub>0</sub> - 248, T<sub>3</sub>N<sub>0-3</sub>M<sub>0</sub> - 99, T<sub>4</sub>N<sub>0-3</sub>M<sub>0</sub> - 32. Conducted 189 resections of the lower lip (77 of them on the author's method of cheiloplasty), 222 cervical lymph node dissection (41 of them - modified). Long-term results of treatment were evaluated by Kaplan-Meier. Results. Cancer recurrence after X-ray, the combined and surgical treatment diagnosed in 241 (62 %), 6 (19 %), and 7 (12.2 %) patients, respectively. 3- and 5-year survival of patients were 56.7±2.3 and 49.6±3.4 %, 76.0±9.3 and 70,7±11,9%, 77.6±7.9 and 72.4±8.3 % for all stages of cancer after X-ray, the combined and surgical treatment methods, respectively. Conclusions. It is necessary to conduct active surgical tactics in the treatment of cancer of the lower lip. Cheiloplasty method and a modified version of the functional neck dissection may reduce postoperative complications and recurrences.
