Active clinical trials for "Gastrointestinal Neoplasms"

This study is a first-in-human (FIH), single-dose, open-label, phase 1 study designed to assess the safety, pharmacokinetics (PK), distribution, and radiation dosimetry of [68Ga]MLN6907 after a single intravenous (IV) administration. Patients with Metastatic Colorectal Carcinoma who are scheduled for resection of liver metastases as part of their treatment plan will be eligible for enrollment.

The purpose of this study is to study whether adding Aprepitant to Palonosetron and dexamethasone can further prevent the incidence and severity of nausea and vomiting caused by FOLFIRI or FOLFOX chemotherapy regimen among gastrointestinal malignancy patients with high risk factors of chemotherapy-associated adverse events.

This study evaluates longitudinal data associating changes in gut microbiota composition and diversity, defecation, performance status and adverse reactions in response to prebiotic fiber supplementation in patients with gastrointestinal cancer chemotherapy-related diarrhea. 120 adult participants , age 18 to 65 years, will be randomized into one of the two arms. Arm A (intervention group) will receive prebiotic fiber and loperamide hydrochloride capsule(a drug for standard treatment). Arm B will receive maltodextrin placebo and loperamide hydrochloride capsule.

According to the total population of cancer patients, hepatocellular carcinoma (HCC) and colorectal cancer (CRC), two of gastroenterological cancers are involved in the most acquired five cancers. Colorectal cancer (CRC) is a leading cause of tumor-related morbidity and mortality worldwide, and HCC is one of the top ten cancers in China. Currently, the intervention for gastrointestinal cancers mainly focuses on surgical removal, but patients still have a high risk of recurrence. Thus, the prevention of cancer recurrence is the most crucial topic for the intervention. The pathophysiology of gastroenterological cancers is multifactorial and not yet completely understood. However, immunosuppression is a major contributing factor in tumor cells play a central part in disease progression. It determines the prognosis of patients.

It is the hypothesis of this project that the Mesenteric Traction Syndrome (MTS) is a common event during upper gastrointestinal cancer surgery (UGC surgery) and that the induction of the syndrome is an important factor in provoking further peri- and postoperative complications and in worsening the surgical stress response (SSR). The characteristics of MTS is hypotension, tachycardia, and flushing. In order to uncover the role of MTS in cancer surgery and the effects on the oncological patients, the aim of the project is: 1. To characterize MTS in patients undergoing three common forms of UGC surgery using a new objective methodology and by recording biomarkers suspected of playing a role in the pathophysiology of MTS and postoperative complication development. Three different interventions will be examined during this prospective trial: Continuous measurement of microcirculation on the forehead using Laser Speckle Contrast Imaging during surgery. Analyses of plasma samples obtained pre-, intra-, and one day postoperatively. Continuous measurements of haemodynamic variables during surgery.

The purpose of this multicenter imaging sub study is to evaluate the biodistribution and organ pharmacokinetics of 89Zr-MMOT0530A in patients with unresectable pancreatic or platinum-resistant ovarian cancer. MMOT0530A is a monoclonal antibody that targets an antigen overexpressed in pancreatic and ovarian cancer. Subsequent to imaging with 89Zr-MMOT0530A, patients will be treated with DMOT4039A in the DMO4993g protocol (clinicaltrials.gov identifier NCT01469793) after this study. DMOT4039A is an antibody-drug conjugate composed of the monoclonal antibody MMOT0530A and the mitotic agent monomethyl auristatin (MMAE). By imaging patients with the monoclonal antibody MMOT0530A before treatment, the correlation between tumor uptake of 89Zr-MMOT0530A and response to DMOT4039A therapy will be assessed.

Several studies have shown that tumour hypoxia may have a negative impact on the outcome of anticancer treatment. Assessment of tumor hypoxia at baseline or shortly after start of treatment may serve as a predictive marker to determine treatment efficacy at an early stage. Preferably, such an assessment is performed in vivo and non-invasively.Non-invasive imaging with positron emission tomography (PET) using the 2-nitroimidazole nucleoside analogue, 3-18F-fluoro-2-(4-((2-nitro-1H-imidazol-1-yl)methyl)-1H-1,2,3-triazol-1- yl)propan-1-ol (18F-HX4), was tested as a new marker of tumor hypoxia. Before hypoxia-measurements can be clinically implemented for response prediction, the reproducibility of the technique should be assessed for each specific tumor type. Knowledge of reproducibility is needed to determine what change in parameters between two examinations can be considered relevant in an individual patient. Assessment of reproducibility becomes even more important in early response monitoring since the changes in the tumor induced by the treatment may be smaller during the treatment compared to response monitoring after completion of treatment. Also, as image quality of 18F-HX4-PET increases with increasing time intervals after injection, determination of the optimal time point for measurement of hypoxia is warranted.

Purpose/Goal: To investigate how long course radiation therapy (RT), both with or without chemotherapy, affects the immune system, and to determine if acupuncture can modify these effects in patients undergoing curative radiation therapy for gastrointestinal (GI) or genitourinary (GU) cancers. Clinical or Research Questions: Does RT reduce immune biomarkers in treated subjects? Which biomarkers are most affected by treatment? Is acupuncture a feasible option to help ameliorate any biomarker effects? Does RT affect subject symptoms? Is acupuncture a feasible option to help ameliorate any symptom effects?

The objective of this study is to assess the efficacy and toxicity of a 2 weekly regimen containing irinotecan combined with leucovorin-modified 5-fluorouracil in the setting of relapsed or refractory upper gastrointestinal tumours. Patients with locally advanced or metastatic adenocarcinoma originating from the oesophagogastric junction, stomach or pancreas who have previously received chemotherapy and have either failed to respond or who have relapsed after an initial response will be eligible for treatment in this study. The response rate, failure-free survival and overall survival of treated patients with the two different regimes will be evaluated. Toxicity and quality of life will also be monitored closely.

This is a study examining the effects of different educational-motivational materials about colorectal cancer screening on perceptions and intentions to get screened. Eligible participants will be randomized to one of three experimental conditions. All participants will be provided information about colon cancer and screening options based on the Centers for Disease Control and Prevention Screen for Life materials. Some participants also will be asked to read a personal narrative about colon cancer screening. This study will determine whether participant's perceptions about and colorectal cancer screening intentions and behaviors differ by which information they read. Participants will complete surveys before, immediately after, and one month after randomization. To assess behavior change, as suggested by grant reviewers and the project officer, we added 6 and 12 month follow up surveys.
