Filter by:This is an open-label, single arm study to explore whether 18F-ALF-NOTA-PRGD2 PET/CT scan can predict the efficacy and adverse events of apatinib in patients with malignancies. Integrin αvβ3 has been shown to play an important role in angiogenesis and up-regulated obviously in various types of tumor cells and activated endothelial cells. The arginine-glycine-aspartic acid (RGD) tripeptide sequence can bind to integrin αvβ3 with high affinity and specificity. The 18F-ALF-NOTA-PRGD2 will highly combine with αvβ3, and thus will monitor the antiangiogenic status.In the current study, investigators propose to evaluate the feasibility of 18F-RGD PET/CT in monitoring efficacy and adverse events of apatinib in malignancies.
This is an open label, multi-center, and randomized phase II trial designed to compare the safety and efficacy of direct oral anticoagulants and subcutaneous dalteparin in patients with acute venous thromboembolism and upper gastrointestinal, hepatobiliary, or pancreatic cancer, based on a group sequential design. Enrolled patients will be randomized in a 1:1 ratio. Patients will be stratified by performance status, type of cancer, chemotherapy and medical centers.

Background: Stomach cancer is common around the world. The US is a low-risk region. But the 5-year survival rate in the US is low. This is because the cancer is usually in a late stage by the time it is diagnosed. One way to detect it earlier is to screen many people with a procedure called endoscopy. But this may not be feasible in low-risk or developing countries. Researchers want to find a biomarker for early-stage disease to help them create an effective way of screening. DNA methylation is a chemical modification of DNA. It generates a signal for certain cancers, including stomach cancer. Researchers want to find a blood-based DNA methylation marker for stomach cancer. Objective: To study plasma DNA methylation as a potential biomarker for detection of stomach cancer. Eligibility: Participants from 2 studies already done in China Design: Researchers will use blood samples from participants in the 2 studies. The blood was collected in 1999/2000. They will use samples from some who developed stomach cancer between those years and 2006. The other samples will be from some who stayed cancer free in that time. Participants already gave written informed consent. Researchers will take DNA from the samples. They will look for methylation.
Helicobacter pylori (H.pylori) is a major human pathogenic bacterium in gastric mucosa which is linked to the development of gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma and gastric cancer. However the regulatory mechanism of H.pylori-induced immune response is not clear. Long non-coding RNA (lncRNA) has recently emerged as key post-transcriptional regulators of gene expression, differentiation. The investigators had a preliminary results which THRIL (TNFα and hnRNPL related immunoregulatory lincRNA) and PACER(p50-associated COX-2 extragenic RNA) played a potential role in H.pylori induced inflammatory cascade. However, there wasn't a previous study about expression of THRIL, PACER in a human tissue. Therefore, the investigators aimed to evaluate the expression of THRIL, PACER in patients with gastrointestinal disease according to H.pylori infection.
Background: Gastric cancers are cancers of the stomach. Hereditary ones are passed from parent to child. Researchers want to gather data about hereditary gastric cancers. They want to learn about changes these cause in the body and about the genes involved. Objective: -To gather data about hereditary gastric cancer. Eligibility: - People at least 2 years old with personal or family history with a hereditary gastric cancer. - People at least 2 years old with gene changes that lead to such cancer or a lesion that may be hereditary. Design: - Participants will be screened in a separate protocol. - Participants will have: - Physical exam - Medical history - Blood tests - Scans - Photos of skin lesions and other findings - Gynecology consultation for women - Cheek swab (some participants) - For some participants, their relatives will be asked to join the study. - Some participants will be asked to allow the study to get stored tissue samples for relatives who have died. - Some samples will be sent to outside labs. All personal data will be protected. Samples will be destroyed when the study ends. - Participants will get the results of genetic testing. - Participants who cannot come to the NIH clinic may just give a cheek swab and have genetic testing done. - Some participants will be contacted for more testing.
Background: Certain stomach cancers are rare, but they have high mortality rates. Researchers want to learn more about gastric (stomach) tumors. In this study, they want to collect data from people who have stomach cancer or are at risk to get it. This data will be used to see if the people can be in other studies. Objective: To study tissue from stomach tumors and find people eligible for more studies on gastric cancer. Eligibility: Age greater than or equal to 2 years old who have or may have stomach cancer, lesions that may be related to stomach cancer, or an inherited disorder that leads to stomach cancer. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Heart tests Scans or ultrasound. For the scans, participants lie in a machine that takes pictures. For some scans, they will swallow or be injected with a small amount of radioactive material. Special cameras will show the material in the body. Tumor sample taken with a needle or surgery Some participants will have an endoscopy. A long, flexible tube with a camera will be inserted through the mouth into the stomach. The tube will collect tissue from the stomach. Some participants may have follow-up visits. Some may be invited to join other studies. Others will be contacted by phone to see how they are doing. ...
This research study is being down to find what, effects, good and/or bad, adding Pembrolizumab to standard chemotherapy mFOLFOX before and after surgery have on the patient and the patient's cancer.
Double-blind, randomized clinical trial to assess the effects of 1,55 g/day of n-3 fatty acids from fish oil concomitant chemotherapy in gastrointestinal cancer.
This main purpose of this clinical study is to learn about the safety and activity of margetuximab and pembrolizumab combination treatment in patients with HER2+ gastric and gastroesophageal junction cancer.
