title: [Multidisciplinary treatment of head and neck cancer].
abstract: This presentation deals with multidisciplinary treatment of head and neck cancer, especially focusing on maxillary sinus carcinoma (MSC) and nasopharyngeal carcinoma (NPC). Since 1982, a new multidisciplinary treatment incorporating neo-adjuvant chemotherapy has been introduced in the treatment of MSC. The Neo-adjuvant chemotherapy includes cisplatin (CDDP) + peplomycin (PEP), adriamycin (ADR) analogs + CDDP + PEP, and CDDP +5-FU. Two courses of chemotherapy were given intraarterially with the interval of 2 weeks. Routinely, radiotherapy of 40 Gy by Linac was given to the primary tumor site, concomitantly combined with 5-FU intraarterial injections only during the first 10 days, 2 weeks after the end of chemotherapy. Additional treatment was performed according to the extent of the residual tumors. The 5-year survival rate for the 28 patients treated with this therapy was 55%. The 5-year survival rate by T classification was 100% for T2, 76% for T3 and 0% for T4 cases. The preservation rate of maxillo-facial structures and functions was 82%. Concerning NPC, neo-adjuvant chemotherapy included CDDP + PEP, ADR + CDDP + PEP and ADR + cyclophosphamide + PEP. Two courses of chemotherapy were performed, followed by radiotherapy of 60 Gy by Linac. Then intracavitary 60Co therapy was performed, followed by adjuvant chemoimmunotherapy. The 5-year survival rate for 21 patients treated with this therapy was 44%.
  
  
  CONCLUSIONS
  (1) The 5-year survival rate was better for patients with MSC who were treated with multidisciplinary treatment incorporating intraarterial neo-adjuvant chemotherapy than that for patients who received other treatment so far. Furthermore, the highest preservation rate of maxillo-facial structures and functions was achieved in the neo-adjuvant chemotherapy group. However, survival rates for T4 cases were very poor, so another approach should be taken. (2) The 5-year survival rate was also better for patients with NPC who were given multidisciplinary treatment than for patients who received other treatment to date. However, there was no decrease of distant metastases, which we aimed initially, despite the introduction of neo-adjuvant chemotherapy.
