High complete response in advanced nasopharyngeal carcinoma with bleomycin, epirubicin, and cisplatin before radiotherapy.
Undifferentiated carcinoma of nasopharyngeal type (UCNT) is a geographically endemic, Epstein-Barr virus-related carcinoma of epidermoid origin with reported 5-year survival rates of 15%-40% when treated with radiotherapy alone. Although UCNT can be well controlled locally by radiation therapy, in advanced nodal stage N3 [International Union Against Cancer-American Joint Committee on Cancer (UICC-AJCC, 1987)] the survival rate is below 20%, primarily because of metastatic spread in 80% of the fatalities. We report a pilot study of 41 patients with nonmetastatic, locoregionally advanced disease (85% of the patients had a nodal status greater than or equal to N2C-N3; 43% had T4 primaries), during which we used a combination of 100 mg of cisplatin/m2 on day 1, 15 mg of bleomycin by intravenous push and 12 mg/m2 by continuous infusion on days 1-5, and 70 mg of epirubicin/m2 on day 1 every 21 days for three cycles before definitive radiation therapy with 70 Gy for 7 weeks. Twenty-seven of 41 patients (66%; 95% confidence interval = 52.5%-80.5%) achieved a clinical complete response, and 40 of 41 (98%) had a major objective response after chemotherapy. Two deaths were treatment related, but side effects were moderate, and the overall treatment sequence was feasible. At the end of radiation therapy, all 39 assessable patients were in complete response, with a median follow-up of 21+ months (greater than 10-greater than 31); 33 (80%) patients had no evidence of disease. We believe that such a complete response rate in a high-volume disease with the use of combined modality treatment indicates a therapeutic gain in UCNT. Researchers performing a multicenter international controlled trial will test this hypothesis and compare local control, disease-free, and overall survival of the therapeutic sequence presented here with radiotherapy alone.
