Independent Risk Factors Analysis and Model Construction For Recurrence After Radiofrequency/Microwave...
Colorectal Cancer With Liver MetastasesThis study is a retrospective, multicenter clinical study. The main objective is to analyze the risk factors affecting the recurrence of colorectal cancer patients with liver metastases who received radiofrequency/microwave ablation. Finally, we will construct a recurrence risk prediction model based on the risk factors and validated the model.
An Observational Cohort Study to Assess the Postop Activity of Colorectal Patients Undergoing Elective...
Colorectal (Colon or Rectal) CancerAll participants will have a physical activity monitor placed onto the right thigh in the midline which will start collecting data at midnight on the first postoperative day. This will continue until discharge or day 7, whichever is earlier. This is a non-invasive measure of activity and can discriminate between whether a patient is lying, sitting, standing or walking. There is no control group.
The Predictive Value of Guangzhou Panel for Recurrence in Early-stage Colorectal Cancer
Colorectal NeoplasmsThis study aims to evaluate the predictive value of a four-gene methylation assay called Guangzhou Panel in early-stage colorectal cancer. Patients will be divided into two groups: high risk group and low risk group. The primary endpoint is 5 year disease free survival (DFS).
Study of Chemotherapy With or Without Hepatic Arterial Infusion for Patients With Unresectable Metastatic...
Colorectal Adenocarcinoma Metastatic to the LiverThe purpose of this study is to see if patients treated with both regional chemotherapy using the HAI pump and intravenous chemotherapy are able to have their liver tumors removed surgically (resected), versus treatment with only intravenous chemotherapy.
Preventive Treatment of OxaLiplatin Induced peripherAl neuRopathy in Adjuvant Colorectal Cancer...
Colorectal CancerChemotherapy-induced Peripheral NeuropathyThis study is to evaluate PledOx for prevention of chronic chemotherapy induced peripheral neuropathy induced by oxaliplatin in patients with Stage III or high-risk Stage II colorectal cancer (CRC).
Gluteal Squeeze for Left Colon Distension
Colorectal NeoplasmsGood distension of the colon during colonoscopy is essential to detect polyps. Gas sometimes escapes the colon through the anus resulting in compromised distension. Pressure on gluteal muscles when the colonoscope tip is in the left colon might help preventing this and thus increase visibility. No previous study looked at this.
The Utility and Feasibility of Mt-sDNA as a Surveillance Procedure in Colorectal Cancer Survivors...
Adenocarcinoma of the ColonAdenocarcinoma of the Rectum3 moreThe purpose of this research study is to determine whether testing of stool for a panel of markers will enable us to detect polyps and cancer compared to standard testing.
Molecular Characterisation of Colorectal Cancer Peritoneal Metastases
Colorectal Cancer MetastaticThis project aims to characterise the tumour cell and tumour microenvironment of colorectal cancer peritoneal metastases, understand molecular changes leading to colorectal peritoneal metastasis, identify potential biomarkers and novel treatment strategies.
SCar-biopsies After Malignant Colorectal Polypectomy of Uncertain RAdicality
Colorectal CancerAfter endoscopic removal of a colorectal polyp that harbors (unexpected) adenocarcinoma, pathology usually can not guarantee a radical resection from an oncological point of view. In such case, additional surgical resection is advised. However, only in 15% of patients, residual adenocarcinoma is found. This study investigates the sensitivity of biopsies from the polypectomy scar for residual adenocarcinoma.
Double-balloon Colonoscopy to Increase Colonoscopy Completion Rate
Colorectal CancerColorectal Adenomas1 moreThe aim of colonoscopy is to visualize the inside of the entire large bowel. Several factors can make the procedure difficult, and sometimes a complete examination is not possible. Complicating factors include poor bowel preparation and technical challenges such as differences in anatomy (long, redundant colonic segments), post-surgical adhesions, strictures and diverticulosis. A special endoscope with two inflatable balloons, originally designed to examine the small bowel, has been used for several years with success in such technically difficult colonoscopies. More recently a modified double-balloon instrument was designed specifically for colonoscopy, but the documentation of the performance of this instrument is limited. The aim of the present study is to investigate the performance of the double-balloon colonoscope in cases where conventional colonoscopy have failed due to technical difficulties.
