Filter by:Gastroentero-pancreatic neuroendocrine tumors (GEP-NETs) are a heterogenous group of neoplasms that arise from enterochromaffin cells of the gastrointestinal (GI) tract and pancreas. They account for 50-70% of all incident NETs. Due to the lack of symptoms in the early stage of disease and the frequency of nonspecific GI symptoms, GEP-NETs are difficult to diagnose. Identification of effective biomarkers (such as Chromogranin A) to improve GEP-NET diagnosis, as well as to assess treatment efficacy, relapse and prognosis, is important for improving outcomes for patients with GEP-NETs. The purpose of this study is to validate the performance of Brahms (BRAHMS) Chromogranin A II Kryptor (KRYPTOR) assay to monitor the course of disease in patients with well-defined GEP-NETs.
Background: People with hereditary gastric cancer syndrome are at increased risk of getting cancer in their stomach. These people should have regular endoscopies and biopsies to check for cancer if they are choosing to keep their stomach. Researchers want to see if they can improve the detection of cancer by endoscopy. Improved endoscopies could better detect early signs of cancer in people with this syndrome. Objective: To see if a small microscope attached to an endoscope to inspect the stomach lining is better than regular endoscopy to find the first signs of cancer in the stomach. Eligibility: People ages 18 and older who have a personal or family history of a hereditary gastric cancer syndrome or have a mutation that is known to lead to gastric cancer Design: Participants will be screened over the phone or in person with: - Personal and family medical history - Review of their medical records Participants will have a physical exam. Then they will be put under general anesthesia. They will have an endoscopy. A lighted tube will be inserted into the mouth and go down to the stomach. First, the standard device will be used. Then participants will be injected with fluorescein. This is a contrast agent. Then the microscope will be added to the tube and the endoscopic evaluation of the stomach will be repeated. During the procedure, biopsies will be taken from different areas of the stomach. Participants will be observed for a few hours after the procedure. About 14 days after the endoscopy, participants will be asked to return to the clinic for a follow-up visit. This visit can also be conducted over the phone.
The purpose of this study is to determine whether ASLAN001 has an effect in patients with recurrent or metastatic adenocarcinoma of the stomach, gastrooesophageal junction, or lower third of the oesophagus whose tumours over-express HER-1 and HER-2, or whose tumours are HER-2 gene-amplified. Maximum of 26 patients will participate in South Korea and the patients will be assigned to either group A or group B according to the results of tests done on tumor tissue obtained by biopsy to determine HER-1 and HER-2 status.
This is a phase 1, open-label, dose-escalation clinical trial to evaluate the safety and tolerability of ASG-5ME and identify the maximum tolerated dose in patients with pathologically confirmed metastatic pancreatic adenocarcinoma, and to evaluate safety and tolerability in patients with relapsed or refractory gastric adenocarcinoma.
