Filter by:The purpose of this study is to learn if vinflunine can shrink or slow the growth of cancer in patients with advanced or metastatic stomach cancer who have progressed on a prior treatment with a fluoropyrimidine or taxane-containing chemotherapy regimen. The safety of this treatment will also be studied.
RATIONALE: Drugs used in chemotherapy, such as capecitabine and oxaliplatin, 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. PURPOSE: This phase II trial is studying how well giving capecitabine together with oxaliplatin works in treating patients with locally advanced, unresectable, or metastatic stomach cancer.
Esophageal cancer is a common malignancy with a very poor prognosis. The principal reason for its poor prognosis is that most tumors are asymptomatic and go undetected until they have spread beyond the esophageal wall and are unresectable. Significant reduction in esophageal cancer mortality will require successful strategies to diagnose and treat more cases at earlier, more curable stages of disease. A successful early detection program will require an accurate, patient-acceptable screening test, confirmatory tests that can localize precursor and early invasive lesions, and one or more curative therapies that are acceptable to asymptomatic patients. This project includes five studies designed to evaluate techniques that may be useful in such an early detection program: 1. The Cytology Sampling Study will estimate and compare the sensitivity of several cytologic samplers for identifying biopsy-proven dysplasia and cancer of the esophagus. 2. The Mucosal Staining Study will evaluate whether mucosal straining can improve endoscopic localization of esophageal dysplasia and cancer. 3. The Endoscopic Staging Study will evaluate how accurately endoscopic techniques can stage dysplasia and early invasive cancer of the esophagus. 4. The Endoscopic Therapy Pilot Study will evaluate the feasibility, safety, acceptability and preliminary efficacy of endoscopic therapies for removing or ablating focal high-grade dysplasias and early invasive cancers of the esphagus. 5. The Chemoregression Study will evaluate the ability of oral chemopreventive agents to reduce progression or cause regression of low-grade squamous dysplasia of the esophagus. This project will be carried out in Linxian, China, a county with extraordinary rates of esophageal cancer and a correspondingly high prevalence of the asymptomatic precursor and early invasive lesions that are needed for these studies. The project will be a collaborative effort of investigators from NCI, the Cancer Institute of the Chinese Academy of Medical Sciences, and several U.S. universities.
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and capecitabine, 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying how well giving oxaliplatin and capecitabine together with radiation therapy works in treating patients with stomach cancer that can be removed by surgery.
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.
Phase I study: To investigate primary objective (maximal tolerated dose and dose-limiting toxicity) and secondary objectives (pharmacokinetics, safety, estimation of a recommended dose, and anti-tumor effect by evaluable case) of E7070 in patients with gastric cancer who are extensive or intermediate metabolizer type (EM/IM) to CYP2C9 and CYP2C9 by intravenously administering once every 3 weeks. Phase IIa study: To investigate primary objective (response rate for efficacy assessment) and secondary objectives (frequency and severity of adverse drug reactions, and pharmacokinetics) of E7070 in patient with gastric cancer who are EM/IM type by intravenously administering once every 3 weeks.
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.
To compare left thoraco-abdominal approach with abdominal and transhiatal approach to cardia or subcardia cancer
RATIONALE: Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bortezomib together with fluorouracil and leucovorin may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with fluorouracil and leucovorin works in treating patients with metastatic or unresectable stomach cancer.
This clinical trial is studying the amount of EF5 and motexafin lutetium present in tumor cells and/or normal tissues of patients with abdominal (such as ovarian, colon, or stomach cancer) or non-small cell lung cancer. EF5 may be effective in measuring oxygen in tumor tissue. Photosensitizing drugs such as motexafin lutetium are absorbed by tumor cells and, when exposed to light, become active and kill the tumor cells. Knowing the level of oxygen in tumor tissue and the level of motexafin lutetium absorbed by tumors and normal tissue may help predict the effectiveness of anticancer therapy
