Active clinical trials for "Gastrointestinal Neoplasms"

This registry aims to assess real-world long-term disease outcomes for patients treated using reversible electroporation and a chemotherapeutic or calcium; in particular tumour response rates and recurrence rates. The study also aims to characterise side effects and the occurrence of Adverse Events and their relationship to the treatment.

This research is being done to collect and store biological specimens (biospecimens) from people with cancer, regardless of tumor type, who are receiving treatments known or thought to have an effect on the immune system. The goal of this discovery and exploratory study is to: Understand changes in the immune system associated with various cancer treatments, in order to better design new therapies or tests to predict how these treatments might work. Identify risk factors for those who go on to develop side effects from immunotherapy. Participants may be asked to: Donate samples of tumor, blood, lymph nodes, white blood cells, mouth cells (buccal smears) scraped from the inside of participant's cheek, urine, saliva, or other tissue samples. Complete questionnaires about immunotherapy side effects at baseline and with follow-up appointments. Undergo knee x-rays. Allow the use of demographic and clinical information.

The goal of this open-label clinical trial is to assess the feasibility of Ketamine-assisted psychotherapy (KAP) studies for adults with non-operable GI cancers suffering with existential distress. The main questions it aims to answer are: Is it feasible to conduct a KAP study with this population? What is the safety and tolerability of KAP in this population? How prevalent is existential distress in this population? Participants will undergo KAP administered as standard of care at the HMHI Park City Ketamine-Assisted Psychotherapy Clinic and will complete health assessments over the course of the study, as well as during the therapy.

This is a FTiH, Phase 1 IIT to evaluate the safety, feasibility, cellular kinetics (CK), pharmacodynamics (PD), immunogenicity, and preliminary antitumor activity of AZD6422 in adult participants with advanced or metastatic CLDN18.2+ GI tumors.

Currently, the question remains whether palliative primary tumor resection could improve overall survival of minimally symptomatic patients with colorectal cancer and synchronous unresectable metastases. The aim of this study is to determine if there is an improvement in overall survival of palliative primary tumor resection followed by chemotherapy in minimally symptomatic patients with colorectal cancer and synchronous unresectable metastases compared to those of upfront chemotherapy/radiotherapy alone.

This pilot clinical trial studies copper Cu 64 anti-carcinoembryonic antigen (CEA) monoclonal antibody M5A positron emission tomography (PET) in diagnosing patients with CEA positive cancer. Diagnostic procedures, such as copper Cu 64 anti-CEA monoclonal antibody M5A PET, may help find and diagnose CEA positive cancer that may not be detected by standard diagnostic methods.

Background: - Gastrointestinal cancers can occur in the throat, stomach, gallbladder, liver, pancreas, and colon. Researchers are interested in evaluating how active the immune system is in trying to fight the cancer by studying blood and tumor tissue donated from individuals who have been diagnosed with gastrointestinal cancers. Objectives: - To collect blood and tumor samples from individuals who have been diagnosed with gastrointestinal cancers in order to study the immune system s response to the cancer. Eligibility: - Individuals at least 18 years of age who have been diagnosed with throat, stomach, gallbladder, liver, pancreatic, or colon cancer, and are scheduled to be treated at the National Institutes of Health. Design: The study will require at least one but no more than four visits to the National Institutes of Health Clinical Center. Participants will be screened with a physical examination and medical history, and will provide a baseline blood sample for study. Participants will provide additional blood samples 2 and 4 months after the baseline sample, as well as a final sample at the completion of the treatment protocol. Participants will provide tumor tissue samples only if they undergo a surgical procedure related to the treatment for their gastrointestinal cancer. No treatment will be provided as part of this protocol.

Cachexia is a common complication of various advanced malignant tumors, which seriously affects the quality of life and survival time of patients. In view of the clinical problem of non-nutritional response in patients with cachexia, the investigators plan to carry out a clinical case-control study on the intervention of creatine combined with curcumin in participants with cachexia. On the whole, the investigators limited the study subjects to upper digestive tract tumors and diagnosed participants with early cachexia. The main purpose of this study is to determine whether the combination of the two can play a positive and stable role in inhibiting the inflammation of cachexia and improving metabolic status, so that basic nutrition can play a role, in order to reduce the level of skeletal muscle consumption, maintain weight, improve quality of life, save medical costs and extend survival time.

This study assesses the feasibility of SGM-101, a fluorochrome-labeled anti-carcinoembryonic antigen monoclonal antibody, for intraoperative near-infrared fluorescence imaging of colorectal brain metastases by injecting SGM-101 intravenously 3 - 5 days prior to surgery.

Remarkably, the incidence of gastrointestinal cancer cases among cancer types is increasing. Gastrointestinal cancers are one of the 10 most common cancer types in the World. This increase worldwide is remarkable, especially due to the increase in urbanization, consumption of foods rich in animal fat, insufficient dietary fiber intake and lifestyle changes. Cytotoxic therapy, which is used in the treatment of malignant diseases, can cause serious complications in gastrointestinal cancer, distinguishing it from other types of cancer. In addition, patients experience symptoms such as nausea-vomiting, mucositis, diarrhea, and constipation much more severely due to the direct effects of these agents on the gastrointestinal system. For this reason, patients' compliance with the treatment process and their quality of life are seriously affected, and patients have difficulties especially in meeting their self-care needs.
