Filter by:The primary objective of the study is to assess the safety and tolerability of cediranib in combination with Cisplatin plus a Fluoropyrimidine (Capecitabine or S-1) in Japanese patients with previously untreated locally advanced or metastatic unresectable gastric cancer (GC).
RATIONALE: A study that evaluates participants' beliefs about smokeless tobacco products and nicotine replacement therapy may be useful in helping smokers stop smoking. PURPOSE: This clinical trial is studying the acceptability of less harmful alternatives to cigarettes.
The objectives of this study are to evaluate the anti-tumor activity, safety, and tolerability of telatinib when used in combination with chemotherapy (capecitabine and cisplatin) as first-line therapy in subjects with advanced gastric cancer. The primary objective is to assess progression free survival (PFS) in subjects receiving telatinib in combination with chemotherapy (capecitabine and cisplatin). The secondary objectives are to assess overall survival, overall response rate, safety and tolerability, pharmacokinetics and biomarkers.
The primary objective of this study is to determine the efficacy of an Oxaliplatin / Irinotecan / Bevacizumab therapy followed by Docetaxel / Bevacizumab therapy followed by Bevacizumab until progression in the treatment of locally advanced metastatic gastric cancer, in terms of response rates (complete or partial response, determined by radiologic evaluation according to Response Evaluation Criteria in Solid Tumors (RECIST)). Secondary objectives Secondary Objective: To determine the safety profile of a an Oxaliplatin/Irinotecan/Bevacizumab therapy followed by Docetaxel/Bevacizumab therapy followed by Bevacizumab until progression in terms of qualitative and quantitative toxicities from first study treatment dose until completion of study treatment due to progression or for any other reason. Secondary Objective: To evaluate the study population with respect to the following: overall survival (from treatment start until death from any cause) and progression free survival (from treatment start until progression or death from any cause).
The purpose of this study is to provide educational material to promote screening for second primary cancer for the intervention group, or educational material to instruct appropriate use of dietary supplement for the control group.
Background: - Gastric (stomach) cancer is a rare cancer. In most cases, by the time it has been diagnosed it has spread to other organs in the body and the chance of a cure is very small. The standard treatment for gastric cancer is a combination of chemotherapy drugs. - Researchers are interested in finding out if surgically removing all tumors before beginning chemotherapy for stomach cancer can slow or halt its spread better than giving chemotherapy alone. Objectives: - To determine whether tumor removal surgery followed by chemotherapy is more effective in treating gastric cancer than chemotherapy given alone. Eligibility: - Patients 18 years of age and older who have been diagnosed with gastric cancer. Design: - All patients will undergo an initial physical examination, blood tests, imaging scans, and a laparoscopy to determine the extent of the disease. - Half of the participants will be assigned to have surgery first and then chemotherapy; the other half will be assigned to have chemotherapy alone. - The surgery-plus-chemotherapy group will have major surgery to remove all tumors in the stomach and abdominal area, followed by a recovery time of up to 4 weeks. Chemotherapy will begin 6 to 8 weeks after surgery. - The chemotherapy-only group will begin treatment within 2 weeks of laparoscopy. - All patients will receive four chemotherapy drugs: 5-Fluorouracil, leucovorin, oxaliplatin, and irinotecan. The drugs are given intravenously over 2 days every 2 weeks (one cycle) for 12 cycles (about 6 months), either at the National Institutes of Health (NIH) Clinical Center or at home with a referring oncologist. Patients in the surgery group who have tumors in the peritoneum will receive an additional set of chemotherapy drugs in a separate treatment. - During the chemotherapy cycles, patients will provide blood samples approximately once a week and will have physical examinations and scans on a regular basis. - Patients will return to the NIH Clinical Center for follow-up visits about every 4 months for 2 years, then every 6 months for 3 years and yearly thereafter.
This randomized phase II trial studies how well docetaxel, oxaliplatin, capecitabine, fluorouracil, and radiation therapy works compared with fluorouracil when given together with oxaliplatin and radiation therapy in treating patients with cancer of the esophagus or gastroesophageal junction that has spread from where it started to nearby tissue or lymph nodes. Drugs used in chemotherapy, such as docetaxel, oxaliplatin, capecitabine, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving more than one drug (combination chemotherapy) together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
Peritoneal metastases appear in a great proportion of patients affected by gastric carcinoma. Involved mechanisms are poorly understood though experimentally it has been demonstrated that neoplastic cells exfoliated from primary tumor can only implant and proliferate in areas of damaged peritoneum. Objectives: to study ultra-structure of peritoneal surface by electronic microscopy in control subjects and in patients with early or locally advanced gastric cancer looking for spontaneous changes in peritoneal surface not related with surgical injury.
Background: - Researchers are trying to learn what causes certain types of cancer to spread to other organs in the body (metastasis). Cancer tumors may produce a very small number of specific cells (cancer stem cells) that cause the tumors to grow in other organs throughout the body. - By examining cancer tumor tissue, normal tissue, blood, bone marrow, and other body fluids, researchers may determine whether these samples contain cancer stem cells. Cancer stem cells may provide information on whether the cancer will come back or spread before other routine x-ray studies or lab tests indicate its presence. Objectives: - To acquire a collection of solid organ cancer stem cells for future study. - To analyze solid organ cancer stem cells from various types of cancer on a genetic level. - To determine if solid organ cancer stem cells are present in the blood or bone marrow. Eligibility: - Patients 16 years of age and older who have solid organ cancer (cancer in the liver, colon, rectum, anus, pancreas, stomach, breast, skin, muscles, fat, connective tissue, uterus, ovary, cervix, vagina, vulva, or inner lining of the abdomen) or a precancerous growth, and who are scheduled to have a biopsy or surgery to remove the cancer as part of their treatment. Design: - This is a prospective trial designed to procure solid organ cancer stem cells before either surgery or biopsy. - All patients registered to this trial will undergo surgery to extirpate their cancer in the NCI - Prior to surgery or biopsy, 8 tablespoons of blood will be drawn. - During the surgery or biopsy, a sample of normal tissue will be removed along with the cancerous or precancerous tissue. If separate consent is given, samples of bone marrow will also be taken. - After discharge, patients will return to the clinic for routine visits every month for the first 3 months following surgery, and then about every 3 months for 2 years, and then every 6 months for 3 years. During the visits, patients will have routine blood and imaging studies done, and researchers will take additional blood samples (about 8 tablespoons at each visit) and optional bone marrow samples (4 teaspoons every 6 months) to be used for research.
The purpose of this study is to gather information about the use of an investigational drug called Ramucirumab in adenocarcinomas of the stomach or gastroesophageal junction.
