Chemo-radiotherapy in patients with locally advanced nasopharyngeal carcinoma: a radiation therapy oncology group study.
The results of radiotherapy alone for patients with locally advanced (stage III or IV) nasopharyngeal cancer (NPC) are poor in spite of the initial complete clearance. Twenty-seven patients (26 stage IV) were treated with concurrent standard radiotherapy and cisplatin 100 mg/m2 intravenously on day 1 and every 3 weeks for three courses. In 24 (89%) patients, complete response (CR) was achieved. The CR rate was higher for poorly undifferentiated cancer (100%). The major side effects were leukopenia (97%), anemia (54%), nausea and vomiting (81%), stomatitis (92%), and renal impairment (52%). Most of these side effects were either mild or moderate and reversible. All patients finished the radiotherapy dose (greater than 6,450 cGy), 19 (70%) had three courses of cisplatin, and eight had only two courses, six due to drug toxicity. Twenty-six patients with stage IV disease were compared with 78 patients treated with radiotherapy alone by the Radiation Therapy Oncology Group (RTOG). The disease-free survival (DFS), overall survival, and the incidence of distant organ metastasis appear to be better in the combined group. It was concluded that the combination of chemo-radiotherapy in patients with locally advanced NPC needs to be evaluated in a phase III randomized trial.
