Circulating tumour DNA and risk of recurrence in patients with asymptomatic versus symptomatic colorectal cancer.

Background: Multiple initiatives aim to develop circulating tumour DNA (ctDNA) tests for early cancer detection in asymptomatic individuals. The few studies describing ctDNA-testing in both asymptomatic and symptomatic patients report lower ctDNA detection in the asymptomatic patients. Here, we explore if asymptomatic patients differ from symptomatic patients e.

Optimizing Screening for Colorectal Cancer: An Algorithm Combining Fecal Immunochemical Test, Blood-Based Cancer-Associated Proteins and Demographics to Reduce Colonoscopy Burden.

Background: Fecal Immunochemical Test (FIT) is widely used in population-based screening for colorectal cancer (CRC). This had led to major challenges regarding colonoscopy capacity. Methods to maintain high sensitivity without compromising the colonoscopy capacity are needed.

Early detection of colorectal neoplasia: application of a blood-based serological protein test on subjects undergoing population-based screening.

Background: Blood-based biomarkers used for colorectal cancer screening need to be developed and validated in appropriate screening populations. We aimed to develop a cancer-associated protein biomarker test for the detection of colorectal cancer in a screening population.

Methods: Participants from the Danish Colorectal Cancer Screening Program were recruited.

Clean Colorectum at Diagnostic Colonoscopy: Subsequent Detection of Extracolonic Malignancies by Plasma Protein Biomarkers?

Introduction: Most of the subjects undergoing diagnostic colonoscopy do not have neoplastic bowel lesions. Potentially, some of the symptoms may therefore be caused by extracolonic malignancy, and subjects with persisting symptoms may need subsequent examinations. Blood-based, cancer-associated biomarkers may aid in directing the examinations for other specific malignant diseases.

Randomized Clinical Trial of Preoperative High-Dose Methylprednisolone on Postoperative Pain at Rest After Laparoscopic Appendectomy.

Background: Methylprednisolone administered intravenously preoperatively has been shown to reduce pain, nausea, and fatigue after elective surgery. We aimed to show that 125 mg of methylprednisolone given intravenously 30 minutes before laparoscopic surgery for suspected appendicitis would reduce pain at rest during the first 3 postoperative days.

Methods: A multicenter, parallel-group, double-blind, placebo-controlled study was conducted including patients 18 years of age and older with an American Society of Anesthesiologist class of I-III undergoing laparoscopic surgery for suspected appendicitis.

Detection of colorectal neoplasia: Combination of eight blood-based, cancer-associated protein biomarkers.

Serological biomarkers may be an option for early detection of colorectal cancer (CRC). The present study assessed eight cancer-associated protein biomarkers in plasma from subjects undergoing first time ever colonoscopy due to symptoms attributable to colorectal neoplasia. Plasma AFP, CA19-9, CEA, hs-CRP, CyFra21-1, Ferritin, Galectin-3 and TIMP-1 were determined in EDTA-plasma using the Abbott ARCHITECT® automated immunoassay platform.

Recovery and convalescence after laparoscopic surgery for appendicitis: A longitudinal cohort study.

Background: Information about predictors for the duration of convalescence and the overall general wellbeing after laparoscopic surgery for suspected appendicitis is missing in the scientific literature. We aimed to describe and identify predictors for the duration of convalescence and the quality of recovery for patients undergoing laparoscopic surgery for suspected appendicitis.

Methods: A prospective cohort of adult patients undergoing laparoscopic surgery for suspected appendicitis was performed between July 2014 and December 2014.

Protocol Outlines for Parts 1 and 2 of the Prospective Endoscopy III Study for the Early Detection of Colorectal Cancer: Validation of a Concept Based on Blood Biomarkers.

Background: Programs for population screening of colorectal cancer (CRC) have been implemented in several countries with fecal immunochemical testing (FIT) as the preferred platform. However, the major obstacle for a feces-based testing method is the limited compliance that reduces the clinical sensitivity for detection of participants with non-symptomatic CRC. Therefore, research approaches have been initiated to develop screening concepts based on biomarkers in blood.

Discovery and Validation of Plasma-Protein Biomarker Panels for the Detection of Colorectal Cancer and Advanced Adenoma in a Danish Collection of Samples from Patients Referred for Diagnostic Colonoscopy.

Background: Well-collected and well-documented sample repositories are necessary for disease biomarker development. The availability of significant numbers of samples with the associated patient information enables biomarker validation to proceed with maximum efficacy and minimum bias. The creation and utilization of such a resource is an important step in the development of blood-based biomarker tests for colorectal cancer.

Neoadjuvant chemotherapy in locally advanced colon cancer. A phase II trial.

Background: Neoadjuvant chemotherapy has proven valuable in several tumors, but it has not been elucidated in colon cancer. The present phase II trial addressed the issue in high-risk patients selected by computed tomography (CT) scan.

Material And Methods: Patients with resectable colon cancer fulfilling the following criteria were offered inclusion; Histopathological verification of adenocarcinoma, T3 tumor on CT scan with extramural tumor invasion > 5 mm or T4 tumor, age ≥ 18 years, PS ≤ 2, adequate hematology, and informed consent.

[Screening methods for colorectal cancer can be improved].

Screening programmes for colorectal cancer (CRC) are being implemented in various countries worldwide including Denmark. The majority of programmes rely on faecal occult blood testing with subsequent colonoscopy. This approach is challenged by limited compliance, which reduces the efficiency of the screening programme.

[Diagnosis and treatment of acute colonic pseudo-obstruction].

Acute colonic pseudo-obstruction (ACPO), also known as Ogilvie's syndrome, is a clinical condition with acute dilatation of the colon without a provable mechanical cause. Early recognition and treatment of the condition is important in order to improve the outcome. The diagnosis is based on clinical and radiographic findings.

Effect of intermediate care on mortality following emergency abdominal surgery. The InCare trial: study protocol, rationale and feasibility of a randomised multicentre trial.

Background: Emergency abdominal surgery carries a 15% to 20% short-term mortality rate. Postoperative medical complications are strongly associated with increased mortality. Recent research suggests that timely recognition and effective management of complications may reduce mortality.
