Filter by:This is an observational study with the goal to improve the robustness of the scientific evidence linking Fusobacterium nucleatum (Fn) and/or other microorganisms to colorectal cancer (CRC) onset and/or progression. This is an approximately three-year study. There are two phases to this study, including: 1) pilot phase, 2) full study. There are also five arms in this study including cancer-free, pre-cancerous, and Colorectal cancer stages (I-III). The pilot study will include the recruitment of 50 participants per group (i.e., total of 250 participants). The full study will have an additional 150 participants per group (total of 1,000 participants). This study will recruit using clinical sites in the United States. There are 5 timepoints in this study. If the participants are found to be medically eligible through diagnosis and medical information, they will provide samples (including: saliva, blood, urine, stool and tumor biopsy) at each timepoint and during the study. They will also answer health and wellness questions during this study. Additional data collection, including medical data, biopsies and other biological samples might happen at interim timepoints in case of adenoma/cancer disease progression (recurrence, metastasis). The participant's healthcare provider will determine if additional biopsies are required as a part of the standard of care. If collected, additional samples will be sent for research purposes.
The purpose of the study is to determine whether standardized implementation of a scripted template for discussing important issues that arise near the end of life improves the care of those who have advanced cancer.
This is an open-label, stratified, two arm design. All patients receive same initial standard preoperative chemotherapy and surgical resection. Patients will then be assigned to either standard postoperative chemotherapy if node negative at surgery or standard postoperative chemoradiation if node positive at surgery. The primary objective of this study is to determine the feasibility of patients enrolling and receiving either postoperative chemoradiation or chemotherapy alone, based upon nodal status at surgery, following preoperative chemotherapy. The secondary Objectives is to evaluate the rate of cancer recurrence in patients assigned to treatment based upon node status. To explore the potential correlation between changes in expression of a pre-specified panel of genes identified as relevant to gastrointestinal cancers in response to preoperative chemotherapy, using presence of nodal involvement at time of surgery as an indicator of response.
Background: Exome sequencing can identify certain gene mutations in a person's tumor. This can then be used to create cancer treatments. In this study, researchers will make a treatment called a messenger ribonucleic acid (mRNA) vaccine. The vaccine might cause certain tumors to shrink. Objective: To see if the mRNA vaccine is safe and can cause metastatic melanoma or epithelial tumors to shrink. Eligibility: People 18-70 years old with metastatic melanoma or epithelial cancer Design: Participants will be screened under protocol 99-C-0128. Participants will provide samples under protocol 03-C-0277: Participants will provide a piece of their tumor from a previous surgery or biopsy. Participants will have leukapheresis: Blood is removed through a needle in one arm and circulated through a machine that takes out the white blood cells. The blood is then returned through a needle in the other arm. Participants will have many tests: Scans and x-rays Heart and lung function tests Blood and urine tests Participants will receive the mRNA vaccine every 2 weeks for up to 8 weeks. They will get the vaccine as an injection into the upper arm or thigh. They may receive a second course of vaccines if the study doctor determines it is needed. Participants will have follow-up visits approximately 2 weeks after their final vaccine, then 1 month later, then every 1-2 months for the first year, and then once a year for up to 5 years. Each visit may take up to 2 days and include: Physical exam Blood tests Scans Leukapheresis at the first visit
Background: Exomes are the parts of deoxyribonucleic acid (DNA) that make proteins. Researchers are finding a way to read the letters in the exome. Incorrect letters are called mutations. Tumors contain specific mutations. Researchers can find these mutations in tumors to make treatments. Researchers want to use pieces of participants tumors to find the tumor-specific mutations. They also will take participants white blood cells to make a vaccine that they hope will shrink the tumors. Objectives: To see if dendritic vaccine tumor-fighting cells are safe and can cause certain cancer tumors to shrink. Eligibility: Adults ages 18-70 who have metastatic melanoma or metastatic epithelial cancer Design: The first part of this study was done under protocol 03-C-0277. In that study, white blood cells and pieces of participants' tumors were taken to make a vaccine. In this study, participants will get a vaccine every 2 weeks for 8 weeks. It will be given both in a vein and under the skin. At each visit, participants will have a physical exam and have blood taken. They will talk about any side effects they have. After treatment ends, participants will have many follow-up visits for the first year, then once each year after that. Visits will last up to 2 days each. They will include lab tests, imaging studies, and a physical exam. Blood will be taken at each visit. At the first follow-up visit, participants may have leukapheresis, which they also had as part of protocol 03-C-0277. Participants may not have to return to the Clinical Center for these visits.
Intra ocular pressure (IOP) may theoretically increase due to steep Trendelenberg position and studies showed that IOP reaches peak levels after steep Trendelenberg position on an average of 13 mmHg higher than preanesthesia induction values. Major determinants of IOP are aqueous humor flow, choroidal blood volume, central venous pressure and extra ocular muscle tone. Hassen GW et al measured anterior chamber depth in 2 patients with glaucoma and compared the anterior chamber depth (ACD) with the intraocular pressure measured by tonometer. They concluded that bedside ultrasound could be useful in evaluating patient with suspected increased IOP, who are unable to open their eyes.
Background: - Some people with gastrointestinal or ovarian cancer also have ascites. That is free fluid built up in the abdomen. Researchers want to see if a new drug can affect some of the immune cells in the ascites. This may also treat the cancer. Objective: - To look at the immune markers the ascites of people with gastrointestinal or ovarian cancer. Eligibility: - Adults age 18 and older with a malignancy of the GI tract or metastatic ovarian cancer. As a result, they have ascites in the abdomen. Design: - Participants will be screened with: - Medical history, physical exam, and blood tests. - Echocardiogram: sound waves make images of the heart. - Electrocardiogram: measures electrical activity of the heart. - Paracentesis: a needle will be inserted in the abdomen and will remove some of the ascites fluid. - They may have a tumor biopsy. - Participants will get AZD9150 through a vein for 3 hours. They will get this 6 times in cycle 1 and 4 times all other cycles. Each cycle is 28 days. - Each cycle, participants will: - Have a physical exam. - Have blood tests weekly. - Be asked about how they feel and any medicines they are taking. - After every 2 cycles (about every 2 months), participants will have scans and x-rays of their tumor. - Participants will have paracentesis 2 more times during the study. They will have another echocardiogram. - At the end of therapy, participants will have a physical exam and blood tests. They will be asked about how they feel and any medicines they are taking.
Clinical background: Weight loss is a common problem in patients suffering from gastrointestinal cancer. It is demonstrated that the prognosis for cancer patients with weight loss is worse than that for weight stable patients. Malnutrition in cancer patients is associated with a poor prognosis and is an important predictor of mortality. Supplementation with home parenteral nutrition in aphagic and terminal patients has shown improved quality of life, energy balance, body composition and prolonged survival. Aim: The aim of this study is primarily to study the effects of supplementation with parenteral nutrition, to patients with advanced incurable gastrointestinal cancer on lean body-mass and body composition. Patients found to be at nutritional risk will be included in the study and will be randomized to either best supportive nutritional care or best supportive nutritional care and supplemental Parenteral Nutrition. Design: This study is a controlled, randomized trial with two parallel study arms. The study will include patients with advanced GI cancers at nutritional risk, performance status 0-2 and with an expected survival of a minimum of 3 months. A total of 100 patients are planned to be enrolled and randomized to either best supportive nutritional care or best supportive nutritional care and supplemental parenteral Nutrition. Primary endpoint is improvement of lean body mass, and by that improvement of quality of life, performance status and cancer treatment tolerance. Discussion: The planned study will provide important information about the effect of parenteral nutrition in a patient group with advanced gastrointestinal cancer. Palliative treatment strategies are set up to improve quality of life as well as prolongation of life. Parenteral nutrition in this patient group may indeed contribute to both these aspects of palliation.
Pazopanib is a new cancer drug that works by limiting the growth of new blood vessels in tumours. About half of patients who take pazopanib develop high blood pressure (hypertension). This side effect can make patients have to reduce or stop their cancer treatment, and can cause other health problems. The aim of this study is to find out exactly how the drug causes high blood pressure.
The majority of patients with upper gastrointestinal cancer, such as gastric, biliary, or pancreatic carcinoma, present with metastatic disease, and have an extremely poor survival, irrespective the type of treatment modality. The aim of the current monocentric phase II study is to evaluate in these patients the effectiveness of cytoreductive surgery (CRS) plus hyperthermic intraoperative peritoneal chemotherapy with cisplatin (HIPC). The study is designed to have at least 80% power to detect a 40% increase in 1-year overall survival common to all strata (gastric-biliary-pancreas) after CRS+HIPC. Over an anticipated period of 2 years, 60 patients will undergo CRS + HIPC. Translational research will quantify perioperative circulating and peritoneal tumour cells, based on real-time RT-PCR for CEA and EpCAM. Plasma concentration of cytokines will be determined for IL-1β, IL-2, IL-6, IL-8, IL-10, IL-12p70, IL-13, IFN-γ, and VEGF at several time-points. Systemic immunological changes will be assessed by flow cytometric quantification of the relative proportions and absolute numbers of B- and T-lymphocytes, NK cells, effector T cells, HLA-DR+ T cells, and regulatory T cells. Gene-expression studies will be performed using Affymetrix HG U133 Plus 2.0 arrays on primary and metastatic tissue samples.
