| Abstract: | Purpose: To define the maximum-tolerated dose (MTD) of paclitaxel when given as a weekly 96-hour infusion with cisplatin and radiotherapy for patients with esophageal cancer. Patients and Methods: Thirty-four patients with locally advanced esophageal cancer and three patients with local recurrence or positive resection margins were treated. Weekly paclitaxel doses of 10, 20, 30, 40, 60, and 80 mg/m2, given as a continuous 96-hour infusion, were administered with weekly cisplatin, 30 mg/m2 on day 1, weeks 1 to 6, and concurrent radiation (50.4 Gy). Plasma paclitaxel steady-state levels were measured. Results: Dose-limiting toxicity, defined as a treatment break longer than 2 weeks for toxicity, occurred in one patient in the 80-mg/m2/wk dose level. Major causes for any (including ≤ 2 weeks) treatment breaks were mediport complications and neutropenic fever, which occurred mostly at that dose level. At a paclitaxel dose of 60 mg/m2/wk, myelosuppression, mostly neutropenia, was relatively mild and transient; stomatitis, esophagitis, diarrhea, and peripheral neuropathy were uncommon and usually of grade 2 or less. Therefore, the MTD was established at 60 mg/m2/wk. The mean steady-state concentration of paclitaxel at the MTD was 17.2 nmol/L. Complete (RO) resection was possible in 16 (73%) of 22 patients who underwent subsequent surgery, and the pathologic complete response rate was 24%. Conclusion: Weekly, 96-hour infusion of paclitaxel 60 mg/m2/wk, given with concurrent cisplatin and radiotherapy, is a safe and tolerable regimen for patients with localized esophageal cancer. Preliminary efficacy data are encouraging. This regimen is the basis of ongoing Radiation Therapy Oncology Group phase II randomized trials in esophageal and gastric cancers. © 2004 by American Society of Clinical Oncology. |
