Standard of Care Alone or in Combination With Ad-CEA Vaccine and Avelumab in People With Previously Untreated Metastatic Colorectal Cancer

Background: Colorectal cancer is a common cancer in the U.S. It causes the second most cancer-related deaths. The drug avelumab and vaccine Ad-CEA together help the immune system fight cancer. Objective: To test if avelumab and Ad-CEA plus standard therapy treats colorectal cancer that has spread to other sites better than standard therapy alone. Eligibility...

Diagnosis of Lynch Syndrome Based on Next-generation Sequencing in Colorectal Cancer

The purpose of this study is to determine the proportion of patients diagnosed with Lynch syndrome in colorectal cancer patients with the loss of staining by immunohistochemistry (IHC) of any of the mismatch repair (MMR) proteins.

Impact of Proximal Colon Retroflexion in Colorectal Cancer Screening Programme

Colorectal cancer (CRC) is the most common tumor and the second leading cause of death in the Western world. The decrease in incidence and mortality by CRC in the population undergoing screening has been observed. Colonoscopy is the recommended method for detecting tumors in early stages, as well as identifying and resecting adenomatous polyps, which are the precursor lesio...

Assessing How Normal Variations in CT Scanning Affects Its Interpretation

The purpose of the study is to see how measurements of tumor differences vary with slight changes in CT scan parameters. Reproducible radiomic features can be extracted for abdominal tumors, and specifically colorectal liver metastases, imaged with clinical CT scanners even in the setting of variable scan parameters and variable contrast timing. Participants will be consent...

Investigation of the Value of ctDNA in Diagnosis, Treatment, and Surveillance of Surgically Resectable Colorectal Cancer

In this study, investigators aim to investigate the value of circulating tumor DNA (ctDNA) analysis in the diagnosis, treatment, and surveillance of patients with surgically resectable colorectal cancer, by performing serial analysis of ctDNA, next-generation sequencing of surgical specimens, and observation of patients undergoing radical resection of the tumor with or with...

Colorectal Cancer Control in Low Resource Countries: Results From a Prospective Cohort Study of Patients at High-risk for Colorectal Cancer

Patient age 45 year old and above who presented with rectal bleeding at three tertiary hospitals in South West Nigeria were invited for colonoscopy. The clinical information of the patients and the colonoscopy data were analyzed

Response to Different Wheat Genotypes in Not-celiac Wheat Sensitivity

Non-celiac gluten sensitivity (NCGS) is a condition where intestinal and extraintestinal symptoms are triggered by gluten ingestion in the absence of celiac disease and wheat allergy. Despite the great interest in NCGS, much remains unknown about the pathogenesis. Some studies seem to suggest that wheat components other than gluten (i.e. amylase/trypsine inhibitors, ATIs) c...

Intra-gallbladder or Systemic Indocyanide Green Injection Facilitate Cholecystectomy.

We will collect the pre-operative medical history and arrange physical examination, life quality evaluation, blood and biochemical test. The Patients with acute cholecytitis, gallstone or gallbladder polyp without interventional treatment or cholecystitis after percurtaneus gallbladder drainage(PTGBD) were involved in this study. Four laparoscopic ports were introduced and ...

Individualized Management for Long Gap Esophageal Atresia

The treatment of long gap esophageal atresia (LGEA) in neonates is one of the most challenging congenital malformations in neonatal surgery. Usually the proximal and distal segments of the esophagus are too far apart, which leads to primary anastomosis abandoned. Thus various techniques have been used including Circular and spiral myotomies、Foker and Kimura elongation and...

Fibromyalgia-like Joint/Muscle Pain and Synovitis in Non-celiac Wheat Sensitivity Patients

Recently it has been reported that a consistent percentage of the general population consider themselves to be suffering from problems caused by wheat and/or gluten ingestion, even though they do not have CD or wheat allergy. This clinical condition has been named Non-Celiac Gluten Sensitivity' (NCGS). In a previous paper the investigators suggested the term 'Non-Celiac Whe...

Effects of Ancient Grains-based Diet in a Closed Community

Recently it has been reported that a consistent percentage of the general population consider themselves to be suffering from problems caused by wheat and/or gluten ingestion, even though they do not have celiac disease or wheat allergy. This clinical condition has been named Non-Celiac Gluten Sensitivity' (NCGS). In a previous paper the investigators suggested the term 'No...
