Filter by:To investigate the efficacy of capecitabine combined with paclitaxel as neoadjuvant chemotherapy for gastric cancer with liver metastasis only
Background: Endoscopic submucosal dissection (ESD) usually requires adequate level of sedation due to lengthy and uncomfortable procedure. Propofol induced sedation with bispectral index (BIS) monitoring has been reported to lead to higher satisfaction of patients and endoscopists during ESD. However, there is no data about efficacy of midazolam and meperidine induced sedation with BIS monitoring during ESD. This study was to evaluate whether midazolam and meperidine induced sedation with BIS monitoring could improve the satisfaction and reduce the dose of midazolam and meperidine during ESD.
The purpose of this study is to determine whether S-1 and oxaliplatin as neoadjuvant chemotherapy may improve survival benefit compared with control.
Malnutrition is frequently seen in patients on chemotherapy suffering from gastric/colorectal cancer and may worsen the outcome. EPA, a sort of ω-3 PUFA, can modulate immune system. EPA also antagonizes metabolic and inflammatory changes induced by the tumor. This study is to test whether EPA, in combination with enteral nutrition, can improve nutritional/immunologic status, quality of life, and reduce chemotherapy related side effects of these patients.
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, S-1, 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. It is not yet known whether giving oxaliplatin together with S-1 is more effective than giving oxaliplatin together with capecitabine. PURPOSE: This randomized phase II trial is studying how well giving oxaliplatin together with S-1 works compared to oxaliplatin given together with capecitabine in treating patients with recurrent, metastatic, or unresectable gastric cancer.
The purpose of this study is to assess efficacy and safety of docetaxel alone, docetaxel plus cisplatin, and docetaxel plus S-1 in patients with metastatic gastric cancer after failing 1st line chemotherapy with cisplatin plus S-1 or capecitabine
RATIONALE: Collecting and storing samples of tissue, blood, and saliva from patients with cancer to test in the laboratory may help the study of cancer in the future. PURPOSE: This research study is collecting blood and tissue samples from patients with stomach cancer, esophageal cancer, or gastroesophageal junction cancer, studying them in the laboratory, and storing them for future studies.
Colorectal cancer (CRC) is the second leading cause of cancer in Puerto Rico (PR) accounting for approximately 1,500 individuals annually, which represent 12% of all cancer cases in the island. The genetic epidemiology of CRC among Hispanic populations is not well studied, hence studies focused on large, well defined ethnic groups such as Puerto Ricans, are clearly warranted. The first step towards evaluating the molecular, environmental, and genetic epidemiology of CRC in PR is to establish a population-based familial CRC registry. The following specific aims have been proposed: Specific Aim 1: To prospectively identify and recruit approximately 300 CRC probands from two distinct geographical areas in PR (Metropolitan and Southern Region). From each proband the investigators will obtain a pedigree extended to second-degree relatives and cousins. Assuming 10% will be positive for a family history of CRC, the investigators will then recruit all 30 probands with a family history of CRC and a sample of 15 family-history negative probands and obtain: paraffin-embedded tumors blocks, blood samples, risk factor and food frequency questionnaires. Specific Aim 2: To prospectively identify and recruit selected relatives (parents, grandparents, and same generation relatives - cousins and siblings) from the 45 probands identified in Specific Aim 1. In addition, for siblings and cousins of probands (i.e. relatives in the same generation as the proband), the investigators will obtain risk factor and food frequency questionnaires, and for colorectal cancer cases, tumor blocks and pathology reports of their cancers. Specific Aim 3: To estimate from this pilot study the following parameters: (a) response rate of probands and their selected relatives; (b) response rate of participants for each data item; (c) family history of CRC and other cancers; (d) number of living first- and second-degree relatives and cousins of probands; (e) number of these relatives who live in the same household and region/municipality; (f) prevalence/distribution of selected risk factors from the administered questionnaires.
RATIONALE: Studying samples of tissue, blood, urine, stool, and other biological fluids from patients with cancer and from healthy volunteers undergoing colonoscopy or endoscopy may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This research study is looking at gastrointestinal biomarkers in tissue and biological fluid samples from patients and participants undergoing colonoscopy, endoscopy, or surgery.
This study is based on the finding that tumor cells that are grown in the laboratory can be modified in such a way that, when injected to the patient, they will stimulate his/her immune response. This approach will be evaluated in patients with melanoma and colorectal, gastric, ovarian, breast, lung and kidney epithelial cancer. Tumor cells grown in the laboratory will be modified to make them stimulatory to the immune system, irradiated to kill them, and injected to the patient eight times at two-week intervals. This protocol is expected to prolong survival of metastatic cancer patients.
