[Long-term results of complex and combined treatment of locally advanced cancer of the oral mucosa].

The analysis of data on 93 cases of stage III-IV cancer of the oral mucosa showed the superiority of combined treatment over complex in terms of five-year survival: 47 and 20%, respectively (p less than 0.01). However, no significant difference in respect to that parameter was established between the combined treatment group and patients rendered disease-free with complex therapy: 47 and 40%, respectively (p greater than 0.05). In the whole group studied, five-year survival rate was 32 +/- 5%; it was 37 +/- 6 and 25 +/- 7% in patients without and with regional lymph node metastases, respectively.
