Active clinical trials for "Colonic Neoplasms"

Despite modern approaches to the diagnosis and treatment of acute bowel obstruction (ABO), postoperative mortality ranges from 5 to 32%, and complications occur up 23% of cases. One of the formidable infectious and inflammatory complications of ABO is sepsis. The main component of the development of sepsis in ABO is bacterial translocation (BT). BT is the migration of intestinal bacteria or their products through the intestinal mucosa into the mesenteric lymph nodes and further into normally sterile tissues and organs. Today there are several methods for detecting BT: direct method - the detection of 16s rRNA (ribosomal ribonucleic acid) in mesenteric lymph nodes (MLN); indirect method - the detection of serum lipopolysaccharide-binding protein (LBP) and presepsin (Soluble CD14 subtype or sCD14-ST). The aim of this study is to determine the diagnostic and prognostic significance of bacterial translocation as a predictor of the complications development in patients with malignant and benign acute bowel obstruction by assessing the relationship of biomarkers in the systemic circulation (LBP, sCD14-ST) with the detection of microorganism genes (16s rRNA) in mesenteric lymph nodes.

Right sided hemicolectomy is the standard type of operation for cancers in the caecum, the ascending colon.The aim of this study was to compare between laparoscopic and open complete mesocolic excision with central vascular ligation in right colon cancer.

To investigate whether laparoscopic ileocecus-sparing right hemicolectomy is feasible and oncologically safe

Objective: Whether temporary endoscopic decompression by Self-expanding metal stents (SEMS) could allow these patients to undergo successful laparoscopic resection (endo-laparoscopic approach) has never been previously studied. This randomized trial aims to compare this approach with emergency open surgery in the management of obstructing left-sided colon cancer.

This study investigates the genetic factors that may influence the risk of developing colorectal cancer at a young age. Finding genetic markers for colorectal may help identify patients who are at risk of colorectal cancer. Studying individuals and families at high risk of cancer may help identify cancer genes and other persons at risk.

Radiotherapy is used in cancer treatment to eradicate microscopic cancer cells to lower the risk of recurrence. The radiotherapy plan must account for organ movement inside the body to ascertain adequate dose is delivered to the target. Knowledge of the magnitude is crucial to radiotherapy treatment planning. This study aims to quantify the movement of the sigmoid colon between different fractions of radiotherapy treatment (interfraction motion) and within the same fraction (intrafraction motion). This knowledge will help us determine the optimal margin to use in radiotherapy treatment planning.

The purpose of this study is to evaluate, in terms of overall survival, the benefit of monoclonal antibodies in the start time of the diagnosis of advanced disease or administer a deferred basis after progression to treatment with chemotherapy alone. Initially expected target population was 1950 patients (pts), in 2015 protocol was ammended to 1028 patients, because the size was sufficient to evaluate the superiority of the use of monoclonal antibodies the start time of the diagnosis against deferred use, with HR of 0.8, power of 90% and an alpha of 0.05. Finally in July 2018, recruitment was completed with a total of 1104 patients enrolled.

The purpose of this study is to find out how well patients with cancer of the rectum do if they get all of their other treatment - chemotherapy by itself followed by chemotherapy and radiation together - before surgery. Patients have recently been diagnosed with rectal cancer, and the doctors have recommended neo-adjuvant chemo treatment to try to shrink the cancer before removing it.

The standard procedure for treating colonic cancer is changing from open surgery to laparoscopic surgery. Following open colonic surgery patients are fatigued and loss body mass and have a reduction in physical function, but the investigators do not know if this is also the case following laparoscopic surgery. This study examines how fatigue, quality of life, physical function, and body composition changes following laparoscopic colonic surgery. Patients are examined preoperatively and postoperative day 10 and 30.

The purpose of this study is to better understand the genetic causes of cancer and the inherited tendency to develop cancer. To accomplish this, blood specimens and/or saliva samples and/or tumor and normal tissue blocks from patients and families of patients with cancer will be collected. Blood specimens will be frozen and stored for analysis at a later date. Tumor tissue and normal tissue will be stored for analysis at a later date. In order to perform this study, patients and members of their families will be asked to provide blood samples and/or saliva samples. Individuals will be asked to provide a history of cancer in their relatives at the time the blood sample is given. No relatives will be contacted before they have been asked by a family member if they wish to participate in this study. If they do wish to participate, the relatives should indicate this by returning the "Family Member Consent for Contact Form" After we receive this form, arrangements may be made for the family member to send in a blood and/or saliva sample or to come in person to provide the sample to us. Except for family history, no medical information provided by one member of a family will be discussed with other family members. At the end of this form, we will also ask for your permission to be contacted in the future to discuss information about your health, additional research with your samples and/or certain research findings possibly related to your sample.
