Active clinical trials for "Stomach Neoplasms"

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.

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.

This is a multicenter, single arm, open-label Phase 1/2 study of pemetrexed plus cisplatin for patients with unresectable, advanced gastric cancer who had no prior palliative chemotherapy. Phase 1 was designed to determine the optimal dose of pemetrexed for its phase 2, which has been completed and now a total of 60 qualified patients will be enrolled in the phase 2 of this study. The treating physician will determined the maximum number of cycles of pemetrexed plus cisplatin that a patient may receive in this study.

1.Study rationale:There is no standard regimen for the advanced and/or metastatic gastric cancer patients who relapsed after adjuvant chemotherapy or failed to first systemic chemotherapy. 2.Primary Objectives:To evaluate overall response rate according to the Response Evaluation Criteria in Solid Tumors criteria and To investigate time to response 3.Design:single-center, Open label, Phase II study. docetaxel 75mg/m2 administered on day 1 as intravenously combined with intravenous Epirubicin 60mg/m2 given day 2 every 3 weeks. 4.Primary endpoints: Efficacy:overall response rate according to the Response Evaluation Criteria in Solid Tumors criteria, time to response, duration of response, and time to treatment failure. Safety-Adverse events and laboratory tests, graded according to the NCI Common Toxicity Criteria for Adverse Effects (version 3.0).

Pemetrexed has shown an anti-tumor activity in advanced gastric cancer patients in a previous study, while cisplatin is widely used in the combination chemotherapy of gastric cancer. Pemetrexed has shown synergy with cisplatin in preclinical models and in various human cancers. The introduction of vitamin supplementation has made treatment with pemetrexed plus cisplatin safe and well tolerated. The present phase 2 study is an effort to determine the efficacy and safety of the combination of pemetrexed and cisplatin in Korean patients with gastric carcinoma who had no prior palliative chemotherapy for advanced disease. The patients, who will give their consent for participating in this study, will be screened for their eligibility and on meeting pre-defined study eligibility criteria, they will receive an intravenous therapy of the combination of pemetrexed and cisplatin for number of times that in the opinion of their treating physician is appropriate for them. A response rate of 30% is considered as the minimum activity level of interest for this patient population.

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.

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 lapatinib works in treating patients with locally advanced or metastatic stomach cancer. Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining oxaliplatin with capecitabine in treating patients who have advanced esophageal cancer or stomach cancer.

RATIONALE: Drugs used in chemotherapy, such as irofulven, use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This phase II trial is studying how well irofulven works in treating patients with recurrent or metastatic gastric cancer.
