Filter by:This study is an open-label, single center, and a dose-escalating phase I study to determine the maximal tolerated dose and the recommended dose of S-1 combined with irinotecan/oxaliplatin in patients with unresectable or metastatic colorectal or gastric carcinoma.
Gastric cancer is the second leading cause of cancer deaths in the World. In China, gastric cancer exceeds all other cancer mortality except lung cancer. Helicobacter pylori infection is an important cause of gastric cancer. We have previously started a randomized placebo-controlled chemoprevention trial in Changle in 1994 to address the issue of whether eradication of H. pylori alone is able to prevent or reduce the risk of gastric cancer. The project involved 1600 subjects and is still ongoing. On the other hand, our laboratory research indicated that an abnormally high expression of an enzyme cyclooxygenase-2 was found in gastric cancer and inhibition of this enzyme by a new drug (specific cyclooxygenase-2 inhibitor) could kill the cancer cells. The same drug is approved now for use in treatment of hereditary colon cancer syndrome (Familial Adenomatous Polyposis, FAP), in the same rationale of tumour suppressive property of this drug. We are now initiating a second chemoprevention study to assess the addition of this specific cyclooxygenase-2 inhibitor together with eradication of H. pylori on prevention or reduction of the risk of gastric cancer and to assess whether the combination can reverse pre-cancerous lesions in the stomach in the high-risk population. The proposed site is Shangdong, China with very high prevalence of pre-cancerous lesions in asymptomatic H. pylori carriers. We plan to recruit 1500 H. pylori positive subjects for this randomized placebo-controlled study. H. pylori carriers will be randomized to receive treatment for the infection or placebo, followed by specific COX-2 inhibitor or placebo for 3 years. The results will have significant impact on prevention of gastric cancer on a national scale and worldwide.
The purpose of this study is to evaluate the efficacy and safety of combined chemotherapy and radiotherapy (in comparison to chemotherapy alone) as adjuvant treatment after surgery for gastric cancer. Prior to surgery all patients will receive neo-adjuvant chemotherapy as well.
The purpose of this research study is to determine if the combination of docetaxel, cisplatin, irinotecan and bevacizumab will help shrink metastatic esophageal or gastric cancer and how the cancer responds to this combination. Bevacizumab is a new drug that is believed to stop the formation of new blood vessels that carry nutrients to tumors. Bevacizumab is approved for use in metastatic colon and rectal cancer. Docetaxel, cisplatin and irinotecan are traditional chemotherapy agents that have been tested together in another clinical trial for esophageal and gastric cancer. Of the 40 patients on this trial, 60% of the patients showed a response of some kind and the regimen was well tolerated. It is hoped that adding bevacizumab to this regimen will make the treatment more effective.
To compare the combination of irinotecan, leucovorin and 5-FU (ILF) with ILF plus cisplatin (PILF) as first-line chemotherapy in patients with measurable metastatic gastric cancer.
This study is for people with advanced gastric or gastroesophageal cancer. This study is being done to find out how long it takes tumors to grow after patients take the drugs capecitabine, oxaliplatin and cetuximab. Capecitabine (also called Xeloda) is a drug that has been approved by the Food and Drug Administration (FDA). Capecitabine has been approved for treatment of cancer of the colon and rectum. Oxaliplatin is another drug approved by the FDA. Oxaliplatin is also approved for treatment of cancer of the colon and rectum. Cetuximab is also a drug approved by the FDA for the treatment of cancer of the colon and rectum, as well as cancer of the head and neck. Capecitabine, oxaliplatin and cetuximab are not approved for gastric or gastroesophageal cancer. They are considered experimental drugs for this study. The purpose of this study is to see how long it takes patients' tumors to progress when they are taking oxaliplatin and capecitabine. Another purpose is to see how many tumors respond to this drug combination. The investigators also want to see how long people live when taking these drugs. The side effects of this drug combination will also be evaluated. This study will also measure the levels of certain genes (the cell's blueprint) in tumors. These genes affect how peoples' bodies react to the cancer drugs. Genes will also be measured in the blood. The investigators want to see how these genes can predict response to these study drugs.
The purpose of this study is to investigate the effect of selective COX-II inhibitor in patients with regionally disseminated stomach cancer treated by palliative resection (so called R1 or R2 gastrectomy).
The purpose of this study is to investigate the efficacy of selective COX-II inhibitor in patients with curative resection performed for locally advanced stomach cancer.
RATIONALE: Drugs used in chemotherapy, such as S-1 and irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving chemotherapy before surgery may shrink the tumor so that it can be completely removed. PURPOSE: This phase II trial is studying how well giving S-1 together with irinotecan works in treating patients who are undergoing surgery for locally advanced stomach cancer.
RATIONALE: Drugs used in chemotherapy, such as S-1 and cisplatin, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. Giving combination chemotherapy before surgery may shrink the tumor so that it can be removed. PURPOSE: This phase II trial is studying how well giving S-1 together with cisplatin works in treating patients who are undergoing surgery for stage IV gastric cancer.
