    Abstract:
    BACKGROUND: Neoadjuvant chemotherapy has been reported to be extremely active in head and neck cancer but has failed to give a statistically significant improvement in survival. METHODS: From 1981 to 1994, 33 operable patients with locally advanced oral cavity cancer received cisplatin-based chemotherapy before surgery. Postoperative radiotherapy was performed in high-risk patients. RESULTS: The overall clinical and pathologic complete response rates to neoadjuvant chemotherapy were 48% and 30%, respectively. At a median follow-up of 7.0 years (range, 0.3-15.3+ years), the 5-year and 10-year overall survival rates were 54.5% and 39.5%, and the disease-specific median survival was 6.6 years for all patients (8.3 and 2.3 years for stages III and IV, respectively). The univariate analysis showed a positive relationship between survival and male sex (p = .05), pathologic (p = .02), and clinical (p = .03) complete response. The Cox proportional hazard regression model confirmed the independent prognostic value of the clinical response with a 4.67 (95% CI, 1.70-12.86) hazard ratio. A second primary tumor occurred in six patients (18%), with a median of occurrence of 9 years (range, 7-11 years). CONCLUSIONS: This study confirms the prolonged survival expectancy largely exceeding 5 years for selected patients with stage IV and for most with stage III locally advanced oral cavity cancer achieving a clinical and/or pathologic complete response to chemotherapy.
