The primary objective is to determine the tumor response rate of bi-weekly docetaxel plus 24-hour infusion of high-dose 5-FU/leucovorin chemotherapy for patients with inoperable advanced gastric cancer.
Gastric cancer is one of the leading causes of cancer death in Taiwan. We have previously demonstrated that weekly 24-hour infusion of high-dose 5-fluorouracil (5-FU) and leucovorin is an effective and well-tolerated regimen for patients with advanced gastric cancer. Our in vitro and clinical studies suggested that long (24 hours or more) infusion of 5-FU/leucovorin may, compared with the conventional bolus regimens, enhance its anti-tumor activity in gastric cancer by prolonging suppression of thymidylate synthase, the target enzyme of 5-FU cytotoxicity. Docetaxel, a mitotic inhibitor, has good single-agent activity against gastric cancer, with a tumor response rate around 20 to 24%. Preliminary clinical data indicate that a biweekly administration of docetaxel will reduce the incidence of neutropenia and asthenia, two most bothersome side effects of tri-weekly and weekly docetaxel, respectively, while maintaining its anti-tumor activity. This phase II trial is designed to test the efficacy and toxicity of biweekly docetaxel and 24-hour infusion of high-dose 5-FU/leucovorin as first-line therapy for patients with inoperable advanced gastric cancer.

Previous radiotherapy is allowed if the treatment was completed at least 4 weeks before the enrollment into this study.
Patients of childbearing age should have effective contraception during the study period.
All patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional guidelines.
Patients who are receiving concurrent radiotherapy, chemotherapy or other experimental therapy.
Patients who refuse port-A catheter implantation.
Patients with brain or leptomeningeal metastases.
Patients who have significant cardiac arrhythmia or acute myocardial infarction within 6 months before entry.
Patients who have major systemic diseases that the attending physicians considered inappropriate for systemic chemotherapy.
Life expectancy of less than 2 months.
Pregnant or nursing women may not participate. Women or men with reproductive potential may not participate unless they have agreed to use an effective contraceptive method.
No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancers, in situ cervical cancer, adequately treated stage I or II cancer from which the patient is currently in complete remission, or any cancer from which the patient has been disease-free for 5 years.
