AbstractWe evaluated the efficacy and toxicity of a novel chemotherapy regimen that included paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ), carboplatin, and long-term, continuous-infusion 5-fluorouracil in the treatment of cancers of the upper aerodigestive tract. In the preoperative treatment of patients with localized esophageal cancer, we administered this regimen concurrently with radiation therapy. Thirty-eight patients with biopsy-proven cancers of the head and neck or esophagus entered this trial between January 1996 and November 1996. Patients with head and neck cancers considered curable with local treatment modalities were excluded. All patients received the following chemotherapy regimen: paclitaxel 200 mg/m2 via 1-hour intravenous infusion on days 1 and 21, carboplatin at an area under the concentration-time curve of 6.0 intravenously on days 1 and 21, and 5-fluorouracil 225 mg/m2/d via continuous infusion on days 1 to 42. Patients with localized esophageal cancer also received radiation therapy beginning on day 1 (1.8 Gy/d; total dose, 45 Gy). Patients were re-evaluated at week 6; responding patients received a repeat course of treatment, except for those with localized esophageal cancer, who underwent resection at week 10. Twenty-five of 29 evaluable patients had major responses to treatment. Four of five patients with locally advanced head and neck cancer had complete clinical responses, while eight of 11 patients with metastatic disease responded. All 13 evaluable patients with localized esophageal cancer underwent resection, and nine (69%) had a pathologic complete response. Toxicity was moderate, with brief grade 3/4 leukopenia occurring in 19 patients (66%). Esophagitis occurred in five of 13 patients receiving concurrent chemotherapy and radiation therapy, but was reversible and generally occurred during the last week of radiation therapy. Other grade 3/4 toxicity was uncommon. This novel regimen of paclitaxel, carboplatin, and long-term 5-fluorouracil infusion is feasible and highly active in patients with cancers of the upper aerodigestive tract. It can be used concurrently with radiation therapy before resection for localized esophageal cancer. The high overall response rates, and particularly the high pathologic complete response rates in resected patients with esophageal cancer, are encouraging and warrant further evaluation of this regimen.
