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.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) appears to be one of the most active drugs in the treatment of advanced head and neck cancer. The maximum tolerated dose of paclitaxel in combination with carboplatin is currently being evaluated in phase I/II studies. We designed a phase II study to evaluate the activity and acute and cumulative toxicity of this combination in patients with recurrent or metastatic cancer of the head and neck. Chemotherapy consisted of paclitaxel 200 mg/m2, given as a 3-hour infusion, and carboplatin dosed to an area under the concentration-time curve of 7 mg x min/mL, administered every 28 days. Granulocyte colony-stimulating factor (5 microg/kg) also was given on days 2 to 12 of each cycle. At the time of this report, 41 patients had entered this study. Primary sites included the nasopharynx (10 patients), larynx (18), oral cavity (three), oropharynx (six), hypopharynx (three), and unknown (one). Among 25 evaluable patients with non-nasopharyngeal cancer, there were two complete responses and three partial responses, for an overall response rate of 20% (95% confidence interval, 4% to 36%). Among eight evaluable patients with nasopharyngeal cancer, four achieved a complete response and two a partial response. Grade 3 to 4 toxicities included anemia (2.5%), leukopenia (7.5%), thrombocytopenia (5%), vomiting (5%), stomatitis (2.5%), and infection (5%). These preliminary data indicate that the combination of paclitaxel and carboplatin is active against advanced head and neck cancer, particularly when used in the treatment of nasopharyngeal cancer.

A randomised trial was undertaken to compare the effect of three oral care protocols in delaying the onset of stomatitis and reducing oral injury in nasopharyngeal cancer patients undergoing radiotherapy, 30 eligible patients with a mean age of 56.2 years were recruited and evenly allocated to one of the three groups using a randomly permuted blocks method. Patients allocated to group E1 and group E2 were given the same instructions on oral care at 1 day, and 1 week before radiotherapy, respectively, while those allocated to the control group were given no instructions. We use the Oral Assessment Guide to assess the oral physical conditions of these patients daily. Our findings revealed that the patients in the E2 group not only had later onset of stomatitis than those in the control and the E1 groups, but also had lesser degree of oral injury measured by the overall assessment score. We thereby recommend the use of the E2 protocol for delaying the onset of stomatitis and reducing oral injury in nasopharyngeal cancer patients undergoing radiotherapy.
