View clinical trials related to Gastrointestinal Cancers.
Filter by:Prospective, multi-center, open label, non-randomized clinical trial to assess efficacy of [18F]FAPI-74 to detect FAP expressing cells in patients diagnosed with gastrointestinal cancers, including hepatocellular carcinoma, cholangiocarcinoma, gastric, pancreatic and colorectal cancer. The [18F]FAPI-74 PET scan will be acquired in patients with proven GI cancers after initial staging using institutional standard methods. The PET scan results will be compared to FAP immunohistochemistry (as the primary objective) and histopathology (as the secondary objective) of the biopsied or resected tissues.
This is a randomized trial of patients with gastrointestinal (GI) cancers treated at University of California, San Francisco (UCSF) who are starting a new line of systemic therapy to evaluate the feasibility of electronic patient reported outcome (ePRO) platform.
The main aim of this project is to establish an innovative model of a comprehensive precision oncology platform to help individualizing drug therapy for patients with advanced cancers at The Chinese University of Hong Kong. The other objectives include to optimize the genomic matching and access of patients with unique cancer subtypes to the relevant clinical trials of novel therapies, and to construct a personalized drug screening platform for individuals using novel cancer models established from patient-derived cancer cells and tissues. Other objectives include to investigate the utility and feasibility of genomic sequencing using circulating tumor DNA(ctDNA), and to establish a biobank of tumor tissues derived from patients with unique cancer subtypes.
Background: Researchers want to test if certain cells can be re-programmed into stem cells. Stem cells can keep reproducing for a long time. Cells made by stem cells can be turned into different types of cells. These include cancer-fighting cells, skin cells, etc. The stem cells generated in this study will be used to make specific tumor-fighting cells that can recognize different types of mutations in cancer cells. They may also help identify new tumor mutations that may not have been identified yet. Objectives: To test if a certain type of tumor-fighting cells can be re-programmed into stem cells. Eligibility: Participants in another Surgery Branch protocol who are at least 16 years old Design: Participants already gave samples of blood and/or tumor tissue in the other protocol. They do not need to come back to the clinic or give any other samples. Participants will give consent for their samples to be used in this study. Researchers will obtain cells from the samples. They will grow those cells in the lab. They will create stem cells from them. Researchers will do genetic tests on the samples. Most tests will not show important health results. But if they do, the participant will be invited to talk to a genetic counselor and get more detailed testing to confirm the results. Some of the samples and results will be stored indefinitely. They may be used in future research. No personal information will be stored with them. ...
To determine treatment response to surgical debulking and intra-operative Intraperitoneal Hyperthermic Chemotherapy (IPHC) in patients with the following malignancies: Gynecologic cancers (ovarian, primary peritoneal or fallopian tube, and uterine/cervical cancers). Mesotheliomas. GI cancers (Gallbladder, liver, small intestine, pancreas, stomach, colon, appendix). To monitor the toxicities and complications of this treatment regimen. To measure treatment related QOL changes after IPHC.
This phase I dose escalation study will evaluate IGF-Methotrexate conjugate (765IGF-MTX) in patients with advanced, previously treated tumors. 765IGF-MTX is administered as an IV infusion over 1 hour on days 1, 8 and 15 of a 28 day cycle. Treatment continues until disease progression, unacceptable toxicity, or patient refusal. Assessment of response will be confirmed with imaging studies performed at the end of cycle 2 +/- 7 days, and every 2 weeks thereafter.
Hypothesis: Different patients have different biomarkers, if doctors know about the biomarkers of patients; they may be able to prescribe a regimen that is better suited to the patient's specific needs. This is a pilot study. Here, we used whole exon sequencing and Integrated genomic network analysis to identify the biomarker or gene. We aimed to learn if the drug chosen based on biomarkers can help to control metastatic gastrointestinal cancer who had failed from all standard and available regimens.
The purpose of this study is to collect prospective data for use as a comparator for future subsequent studies attempting to increase the efficacy or reduce the toxicity of gamma knife radiosurgery.
Malignant ascites represents a severe clinical problem for physicians and patients being confronted with this common symptom of advanced-stage gastrointestinal cancer. Unfortunately, there is no standardized and evidence-based treatment for malignant ascites and therapies which are commonly being used are only temporarily effective. Newer modes of therapy, such as the application of the tri-functional antibody catumaxomab, are associated with significant side effects and are limited to patients in stages of good overall performance. Therefore, there is still an urgent need for more effective, longer-lasting, and less toxic modes of treatment for peritoneal effusions caused by gastrointestinal cancers. Preclinical data strongly suggest that bevacizumab might be a very effective agent for the treatment of malignant ascites, which is in large part caused by the hyperpermeability-promoting factor VEGF. Emerging clinical results from cancer patients with malignant ascites treated with bevacizumab add further support to this idea. Bevacizumab has been tested in a variety of large clinical trials, has a good toxicity profile, and is effective in a number of human cancers underlying malignant ascites. In the present study, Bevacizumab will be administered as an intraperitoneal infusion at an absolute standardized dosage of 400 mg. This dosage was chosen because it is comparable to the approved standard dosage for intravenous administration which was also used in both studies reporting the successful and safe intraperitoneal administration of Bevacizumab to patients with malignant ascites. Finally, a standardized dosage seems more practical in the particular patient population treated in this study.
This study will help us know the effects of Vitamin D pills in Blacks. The results of this study may be the first step in creating ways to prevent the risks of colon and prostate cancer. It will also help us develop ways to reduce colon cancer and prostate cancer among Blacks. This study will find out if Vitamin D pills can increase Vitamin D to healthy levels in our bodies.
