Filter by:Mixed cancer vaccines, CHP-HER2 protein and CHP-NY-ESO-1 protein, are to be studied to evaluate the safety and immune responses in patients who are positive either or both antigens. Nine patients will be enrolled, who are refractory to standard therapies for cancer or at high risk to relapse. CHP-HER2 and CHP-NY-ESO-1 are subcutaneously given on bimonthly basis, together with OK-432(Picibanil) as an immunoadjuvant. Six doses will be given. Toxicity profiles will be monitored, and antigen specific humoral anad T cell responses will be described.
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.
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.
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.
The aim of this study is to evaluate survival benefit of TS-1 plus cisplatin as a neoadjuvant chemotherapy in gastric cancer patient with resectable type 4 (linitis plastica type) and large type 3 tumor in comparison with surgery alone.
