Prevention of Oesophagus Cancer and Stomach Cancer

Researchers already did studies in low-dose Aspirin for the prevention of heart and blood vessels disease and for the prevention of cancer of the colorectum. In this study, they want to learn whether an effect for the prevention of oesophagus cancer and stomach cancer goes along with the use of low-dose ASA on patients taking this medicine for the prevention of heart and blood vessels disease compared to non-use. To find this out electronic medical records stored in primary care database in the UK, The Health Improvement Network (THIN), will be used.

Drug Sensitivity Screening for Gastrointestinal Cancer

Gastrointestinal Cancer Metastatic

Explore the clinical feasibility of using primary cell culture system to guide gastrointestinal cancer chemotherapy, and establish the correlation between ex vivo drug sensitivity and patient clinical response. Study objectives: Personalized drug sensitivity test for late stage,potentially operable gastrointestinal cancer using patient derived primary cell culture. Explore the clinical feasibility of using primary cell culture system to guide gastrointestinal cancer chemotherapy, and establish the correlation between ex vivo drug sensitivity and patient clinical response. The study will collect primary tumor tissues from stage III/IV gastrointestinal cancer patients who underwent emergency surgeries, and then establish the primary tumor cell library for ex vivo chemotherapy drug sensitivity test in order to: Compare the ex vivo Maximal Inhibition Index(MI) and Drug Sensitivity Index (DSI) with patient's Overall Response Rate (ORR) Provide research support for future clinical treatment. This ex vivo method applies to single or combination drug regimen, and does not require prior knowledge of the specific mechanism for individual patient's drug sensitivity. Previous research as well as literature studies support the close relationship between ex vivo drug sensitivity and in vivo drug response.

The Status of Immune Checkpoints at Gastrointestinal Cancer

Gastrointestinal Cancer

Colorectal cancers are the third most common cancer in the world. In advanced stages of colorectal cancers, peritoneal carcinomatosis and intraabdominal acid development occur. Although stomach cancer is the 5th most common cancer in the world, it is the third cancer with the highest mortality. Pancreatic cancer is one of the highest mortality cancers worldwide. Likewise, in advanced stages of stomach and pancreatic cancer, peritoneal carcinomatosis and intra- abdominal acid development occur. It is known that the immune system plays an important role in tumor development or destruction of tumor. Recent studies have shown that tumor cells develop escape mechanisms in the tumor microenvironment to escape from host immunity. It has been reported that differentiation of T cells towards Th2 and regulatory T cells is also effective in tumor progression(6). Changes in the tumor microenvironment and immune checkpoints are important mechanisms that lead to escape from the immune system. Immune checkpoints are on the agenda especially after 2018 Nobel Prize and they are important molecules in revealing the relationship.In our study, it is aimed to evaluate whether there is a difference in immune control points in patients with end-stage colorectal cancer, gastric cancer and pancreatic cancer compared to patients without malignancy, and the relationship of these parameters with patient survival and tumor spread mechanisms.

Metastatic Gastrointestinal CancerGenitourinary Cancer

Analysis of cell free DNA(cfDNA), unlike tissue biopsy, presents a new tool for the monitoring and treatment of cancer. The investigators have developed a differentiated sequencing assay, Digital Sequencing Technology (DST) that enables detection of rare genomic abnormalities with ultra high-specificity and sensitivity. The investigators assay is able to eliminate the error and distortion created by sample-prep and sequencing processes in standard NGS(next-generation sequencing ) workflows and produce near-perfect representations of all rare variants. The investigators have shown that in sequencing a comprehensive cancer panel of 80kbp in 0.1% cancer cell line titration samples, standard Illumina SBS(sequencing by synthesis ) generates many high-quality false positive variant calls in the range of 0.05-5%, while the investigators assay resulted in highly sensitive and completely error-free variant calls across the entire panel. This work indicates the remarkable potential of using the investigators assay in deep analysis of cfDNA, thereby allowing researchers and clinicians to comprehensively and non-invasively monitor the genetic dimension of cancer throughout the body.

EHR-embedded OCDT in Breast or GI Cancer

Oral Cancer Directed TherapyBreast Cancer2 more

This is research study is for participants with advanced breast or gastrointestinal cancer who have been taking oral chemotherapy medication (Oral Cancer Directed Therapy). This study is to help researchers better understand gaps in assessing oral chemotherapy patient toxicity at home, adherence to treatment and integrate toxicity/adherence reporting.

Consumer-Based Activity Monitor in Evaluating and Measuring Activity of Older Patients With Abdominal...

Malignant Gastrointestinal NeoplasmMalignant Peritoneal Neoplasm

This pilot clinical trial studies how well consumer-based activity monitor works in evaluating and measuring activity of older patients with abdominal cancer undergoing surgery. Consumer-based activity monitor (CAM) may identify patients who are at-risk for increased post-surgery medical problems. With early identification of at-risk patients, CAM provide supervised exercise in the preoperative and postoperative periods to improve over mobility and potentially decrease preoperative complications among patients undergoing major abdominal surgery.
