BACKGROUND: The aim of this study was to evaluate the toxicity and efficacy of the combination of 5-fluorouracil, bleomycin, epirubicin, and cisplatin (FBEC) in the treatment of patients with undifferentiated carcinoma of nasopharyngeal type (UCNT). The study included patients with metastatic or recurrent disease (Group A) and previously untreated patients with locally advanced nonmetastatic disease (T >/= 3 or any T, N >/= 2, M0, according to 1987 criteria of the International Union Against Cancer and the American Joint Committee on Cancer (Group B). METHODS: From January 1992 to November 1996, 49 patients with histologically proven UCNT were treated with intravenous (i.v.) 5-fluorouracil (700 mg/m(2)/day by continuous infusion for 4 days), epirubicin (70 mg/m(2) i.v. on Day 1), Bleomycin (10 mg i.v. bolus on Day 1 followed by 12 mg/m(2)/day by continuous infusion for 4 days), and cisplatin (100 mg/m(2) on Day 5); this regimen was repeated every 21 days. Six cycles were given to Group A (26 patients), with bleomycin omitted during the last 3 cycles. In Group B (23 patients), only 3 cycles were given, followed by conventional radiotherapy (70 gray for 7 weeks). RESULTS: Of the 26 patients entered in Group A, 23 were evaluable for response. Nine complete responses (CRs) and 9 partial responses (PRs) were assessed, for a 78% objective response rate (ORR) (95% CI: 56-92). Three patients are alive with no evidence of disease after 43, 61, and 73 months, respectively. These patients achieved a CR with chemotherapy followed by consolidating radiotherapy to their target lesions. In Group B, the ORR was 91.5%, with 5 CRs (22%) and 16 PRs (69.5%) assessed in the 23 patients. Three months after the end of radiotherapy, the ORR was 87% (20 patients). After a median follow-up of 51 months (range, 24-67 months), 15 patients (65%) are alive without evidence of disease. Forty percent of cycles (51% in Group A, 25% in Group B) resulted in Grade 4 neutropenia, with fever and/or sepsis in 9.5%. Mucositis was seen in 42% of pretreated patients. There were 3 treatment-related deaths (2 from complications of infection and 1 bleomycin fibrosis at a total dose of 160 mg/m(2)), all of them in Group A. CONCLUSIONS: The FBEC regimen has good activity, with durable responses in patients with locally advanced, metastatic, or recurrent UCNT. This regimen is safe for patients with locally advanced disease, but close follow-up and supportive measures are needed when it is used to treat those with metastatic or recurrent disease.
