Filter by:The purpose of this study is to determine the genetic makeup of gastro intestinal stomach tumors (GISTs) from patients enrolled in the A6181112 phase IIIb trial. Tumor samples will be screened for mutations and this information will be used to determine whether the progression-free survival of patients being treated with the cancer medication sunitinib is related to the underlying genotype of their GIST.
Therapies involving the immune system have already shown great promise in early clinical trials for the treatment of renal cell carcinoma and melanoma. One of the great challenges now facing this field is to extend these findings to other cancers. Little is currently understood about the nature of the immune response to more common gastrointestinal cancers. The first goal of this proposal is to collect blood and tissue samples from patients with early or late stage gastrointestinal cancers. These samples will be evaluated to better understand the immune response to these two cancers. The second goal of this proposal is to evaluate the specimens of these patients for changes and genetic markers that correlate with the presence of cancer. The information gathered from these studies will directly enhance our ability to design, conduct and monitor novel immunotherapeutic protocols for the treatment of patients with gastrointestinal cancer.
RATIONALE: Drugs used in chemotherapy, such as capecitabine, streptozocin, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving capecitabine together with streptozocin is more effective with or without cisplatin in treating neuroendocrine tumors. PURPOSE: This randomized phase II trial is studying giving capecitabine together with streptozocin to see how well it works compared with or without cisplatin in treating patients with unresectable or metastatic neuroendocrine tumors.
This study will help us know the effects of Vitamin D pills in Blacks. The results of this study may be the first step in creating ways to prevent the risks of colon and prostate cancer. It will also help us develop ways to reduce colon cancer and prostate cancer among Blacks. This study will find out if Vitamin D pills can increase Vitamin D to healthy levels in our bodies.
The purpose of the study is to collect pancreatic tissue, blood and urine from adults to study pancreatic abnormalities.
This is a phase 2, randomized, double blind, placebo controlled, multi-center study to estimate the improvement in progression free survival (compared to control subjects) and evaluate the safety and tolerability of AMG 386 in combination with Cisplatin & Capecitabine in the treatment of subjects with Metastatic Gastric, Gastroesophageal Junction, or Distal Esophageal Adenocarcinoma. AMG 386 is a man-made medication that is designed to stop the development of blood vessels in cancer tissues. Cancer tissues rely on the development of new blood vessels, a process called angiogenesis, to obtain a supply of oxygen and nutrients to grow.
The purpose of this study is to evaluate the clinical benefit of the KIT inhibitor XL820 in subjects with advanced gastrointestinal stromal tumors (GIST) who are resistant to or intolerant of Imatinib and/or Sunitinib.
The proposal seeks to establish: - A comprehensive compilation (database) of clinical information comprising clinical, histopathological, treatment and follow-up characteristics of past and future gastrointestinal cancer (GIC) cases in Singapore that can be shared by investigators. The characteristics will include clinical (eg age, sex, stage), histopathological (eg. grade, type), treatment (eg. treatment status, regimens) and outcome data (eg. survival, toxicity) from medical records. - A collection (bank) of corresponding frozen and fixed tissue, blood and processed samples (enriched blood mononuclear cells, protein, RNA, DNA, tissue arrays) in Singapore that can be shared by the investigators. - A gastrointestinal cancer co-operative group (GCCG) of clinicians and scientists researching prognostic and predictive markers in GIC, which will benefit from the multidisciplinary knowledge, information and samples of its members.
RATIONALE: Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as irinotecan, 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 vorinostat together with combination chemotherapy may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of vorinostat when given together with irinotecan, fluorouracil, and leucovorin in treating patients with advanced upper gastrointestinal cancer.
The study will determine if changes in expression of markers involved in the 5-FU pathways are associated with response to treatment with the combination of lapatinib and capecitabine independent of tumor erbB2 status.
