Filter by:Phase II: Primary objective: to select one of the 2 test arms (docetaxel with cisplatin, docetaxel with cisplatin and 5-FU), based primarily on complete responses, to advance to a phase III survival comparison against the CDDP + 5-FU control arm. Secondary objective: to evaluate the quantitative and qualitative safety profile of the 2 test groups. Phase III: Primary objective: to detect a statistically significant increase in time to progression (TTP) for the test arm (docetaxel plus cisplatin and 5-FU) relative to the control arm (cisplatin plus 5-FU). Main secondary objective: to detect a statistically significant increase in overall survival (OS) for the test arm (docetaxel plus cisplatin and 5-FU) relative to the control arm (cisplatin plus 5-FU). Other secondary objectives: to compare response rates, time to treatment failure, duration of response, safety profiles, quality of life and disease-related symptoms.Socio-economic data will be collected in order to be able to perform an analysis by country when necessary.
The primary objective of this study is to compare median overall survival of the test arm (docetaxel and S-1) to the control arm (S-1 only) in subjects with advanced or recurrent gastric cancer.
To evaluate the usefulness of chemosensitivity test in evaluating the appropriate adjuvant cancer chemotherapy after gastric surgery
A significant proportion of advanced gastric cancer (AGC) occurs in individuals 65 years of age and older. In addition, patient delay in seeking care for symptoms results in diagnosis at a more advanced stage than that seen in younger individuals. However, clinical trials on gastric cancer rarely have been available to the elderly. Recently oral 5-FU pro-drugs, which have been reported to have clinically significant response rates and survival with mild or negligible toxicities, have been widely used for the patients with AGC. However, few studies have been conducted in elderly patients.
The investigators have initial evidence that the combination of cetuximab and cisplatin-HDFL may further improve the efficacy of the cisplatin-HDFL combination chemotherapy.
The primary endpoint of this phase II trial is the objective tumor response rate. The secondary endpoints include treatment-related toxicity, the clinical benefit response defined by the change in performance status and body weight, the change in quality of life, progression free survival and overall survival. Simon's optimal two-stage design will be used to determine the patient number.
To determine the objective response to oxaliplatin/5FU/leucovorin combination chemotherapy in patients with advanced unresectable or metastatic gastric cancer.
- OBJECTIVES To determine in a prospective randomized clinical trial, the effect of extended lymph node dissection (R3 gastrectomy) versus conventional surgery (R0/1 gastrectomy) on tumor recurrence and survival in Chinese patients with advanced cancer of the stomach (adenocarcinoma invasion beyond submucosa). - STATISTICAL CONSIDERATIONS The major end points are disease free survival and survival. The log-rank test will be used as analytic method on disease-free survival and overall durvival. The follow-up time after treatment is five years. Previous experience provides an estimation of a 20% 5-year survival rate with conventional surgery for gastric cancer. Assuming that this new treatment (radical surgery) may increase the 5-year survival rate to 40%, we estimate that 118 evaluable patients are required to detected a significance at a of 0.05 level and power of 0.8 using a one tailed test. We expect to enter 50 patients per year and finish accrual of patient within 2.5 years.
Gastric cancer is the second most common neoplasm in the world. Early diagnosis and surgical resection improve the survival and the chance of cure. Unfortunately, majority of cases are diagnosed at advanced stage, with only 20% of the patients presenting with localized disease. The five-year survival for gastric cancer of all stages remains at a dismal 8%. Chemotherapy has been used for advanced gastric cancer but with unsatisfactory results. Therefore, new approaches are needed for these patients. Among the newer chemotherapy regimens for advanced gastric cancer include a combination of oral 5-Fluoro-Uracil (FU)-based compound called Capecitabine(Xeloda) and Oxaliplatin. A few phase II studies suggest that the combination regimen is active with overall response rates ranging 30-40%. Several preclinical and clinical studies have shown that the expression of cyclooxygenase enzyme II(COX-2) is upregulated in many pre-neoplastic and neoplastic lesions. Furthermore, there appears to be an association with the overexpression of Cox-2 and the invasiveness of cancer and prognosis. Finally, preclinical and clinical studies suggest selective Cox-2 inhibitors can induce apoptosis in gastric cancer cells and retard tumor progression. Therefore, there is a strong rationale for the combination of a selective Cox-2 inhibitor, Celecoxib, with Capecitabine and Oxaliplatin in a therapeutic phase II trial for patients with advanced or recurrent gastric cancer.
This phase II trial is studying how well giving sorafenib together with docetaxel and cisplatin works in treating patients with metastatic or locally advanced gastric or gastroesophageal junction cancer that cannot be removed by surgery. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as docetaxel and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving sorafenib together with docetaxel and cisplatin may kill more tumor cells.
