    Abstract:
    BACKGROUND: A prospective, randomized study was performed to determine the efficacy of neoadjuvant chemotherapy over radiotherapy alone in patients with locally advanced nasopharyngeal carcinoma. METHODS: From January 1991 to December 1998, 80 patients were enrolled in this study. Patients with locoregional carcinoma of the nasopharynx were randomized to receive two courses of chemotherapy, consisting of cisplatin and 5-fluorouracil (CDDP-5FU), that were administered before radiation therapy (CT arm) or radiotherapy alone. The patients who received neoadjuvant chemotherapy were treated with radiation therapy, which was scheduled to commence 2 weeks after the second course chemotherapy. RESULTS: With a median follow-up of 49 months, a trend toward improved overall survival or disease free survival favoring the CT arm was observed (5-year overall survival rate, 60% vs. 48%; 5-year disease free survival rate, 55% vs. 43%), although this difference was not significant. There were no differences in locoregional failure free survival between the two arms. However, metastasis free survival favored the CT arm, although this difference was not significant. The results also demonstrated that most patients in the CT arm who experienced recurrent disease developed locoregional recurrences before distant metastases, suggesting that improvements in locoregional control may lead to improved disease free survival. CONCLUSIONS: The use of CDDP-5FU chemotherapy prior to radiotherapy in patients with nasopharyngeal carcinoma did not result in a significant improvement in disease free survival or overall survival. However, there was a positive tendency in favor of the CT arm for distant metastasis free survival, although there was no improvement in the locoregional recurrence free survival rate.
