An early phase II study of a 3-hour infusion of paclitaxel for advanced gastric cancer.
The purpose of this study was to evaluate the feasibility and efficacy of 3-hour infusional paclitaxel for the treatment of advanced gastric cancer with measurable metastatic diseases. Eligibility criteria included no more than one regimen of prior chemotherapy. Paclitaxel was administered as an intravenous infusion over 3 hours at a dose of 210 mg/m2 every 3 weeks. Premedication of dexamethazone, ranitidine, and diphenhydramine were given to all patients. Sixteen patients were registered in the study. One patient did not receive paclitaxel because of gastrointestinal bleeding before the initiation of drug's administration. Thirteen of the 15 patients had a prior history of chemotherapy. Although 10 patients (67%) developed grade 4 neutropenia, no serious infections occurred during the study. Nonhematologic toxicities were generally mild. Three (20%) patients who showed evidences of resistance to the previous intensive regimen achieved a partial response. In conclusion, a 3-hour infusion of paclitaxel is a safe and promising treatment for advanced gastric cancer. Paclitaxel appears to be non-cross resistant to other agents that are commonly used for gastric cancer. A large-scale phase II study is now underway.
