Smart Pill for Measuring Gut Health in Colon Inflammation and Colon Cancer
The goal of this observational pilot study with invasive measurements is to explore whether an ingestible sensor pill can be of use in diagnosis or monitoring of disease in patients with ulcerative colitis or colorectal cancer. The main questions it aims to answer are: which changes in bowel environment can …
Examination of the Large Intestine With Camera Capsule in Patients With Blood Stream Infection With Gut-associated Bacteria
The goal of this observational study is to diagnose colorectal cancer or precancerous tumors in participants over the age of 18 hospitalized with blood stream infection with anaerobic gut-associated bacteria. The main question it aims to answer is: • How prevalent is cancer and precancerous tumors in the large intestines …
Prospective Cohort Study on the Relationship Between Exosomal Peroxiredoxin 1 (PRDX1) and Postoperative Liver Metastasis
The occurrence of liver metastasis after curative surgery for resectable colorectal cancer is an important cause of death for patients. Accurately identifying high-risk patients for metastasis and intervening in them has important clinical significance. The pathological examination of surgical specimens failed to fully utilize valuable specimen information and accurately predict …
Development and Validation of a PSN-AI Prediction Model
Heterogeneity concerning survival in synchronous peritoneal metastasis from patients with colorectal cancer exists, thereby further classification is urgently required. This study aimed to validate a PSN-AI model based on DNA ploidy, stroma-tumor fraction, and nucleotyping (PSN) for the prediction of survival of synchronous peritoneal metastasis from colorectal cancer.
A Prospective Multicentre Clinical Study of Dynamic Monitoring of Plasma ctDNA Methylation Markers to Predict Recurrence of Colorectal Cancer After Complete Resection of Peritoneal Metastases
The goal of this clinical trial is to explore the predictive effect of postoperative plasma ctDNA methylation status on postoperative recurrence free survival (RFS) of colorectal cancer patients with peritoneal metastasis after R0/R1 resection. The main questions it aims to answer are: Preoperative and postoperative plasma ctDNA methylation detection (ColonAiQ) …
Structural Characteristics of Trunk and Limb Muscles in Cachectic Colorectal Cancer Patients
Until now, cancer is still associated with high morbidity and mortality, and is therefore a big issue for the public health. Colorectal cancer is the second leading cause of cancer death in developed countries. In advanced colorectal cancer, 60% of these patients develop cachexia. The presence of cachexia plays an …
Serial Gut Microbiome and Bacterial Gene Markers Changes After Endoscopic Resection of Colorectal Advanced Neoplasia
The investigators hypothesize that gut microbiome composition and the four bacterial gene markers (M3) show dynamic changes after endoscopic resection of advanced neoplasia, some key bacteria are associated with restoration of gut microbiome after endoscopic resection.
Fruquintinib Combined With TAS-102 in Refractory Metastatic Colorectal Cancer
Fruquintinib, as a standard treatment for refractory metastatic colorectal cancer (mCRC), has attracted increasing research efforts to explore its innovative strategies in combination with immunotherapy and chemotherapy because of its multi-target mechanism which enhances the sensitivity of the immune system and chemotherapy, aiming to further improve the survival benefits for …
Frailty Score and Postoperative Morbidity in Colorectal Cancer Surgery
This prospective observational study aims to evaluate the independent predictive value of the Edmonton Frailty Index (EFI) in estimating postoperative morbidity among older patients undergoing elective colorectal cancer surgery. Frailty, characterized by a decline in physiological reserves and increased vulnerability to stressors, has been recognized as a stronger predictor of …
Mucosa Adherent Intestinal Microbiome in Microscopic Colitis and Colorectal Cancer
Microscopic colitis (MC) is an inflammatory bowel disease characterized by chronic non-bloody watery diarrhoea and a macroscopically normal colonic mucosa upon endoscopic exploration (colonoscopy). The diagnosis is performed by microscopic examination of mucosal biopsies that reveal specific histopathological change. Between 4-20% of patients with chronic non-bloody diarrhoea who undergo colonoscopy …
