Active clinical trials for "Colorectal Neoplasms"

At Zealand University Hospital, Denmark, the investigators will examine the immune function of patients with colorectal cancer before and after tumor resection. The immune function will be assessed with functional profiling of the immune function (TruCulture®) The study aims to describe alterations in the perioperative immune response to surgery. The generatied knowledge will lead to better under standing of perioperative pathophysiology.

As a good niche for bacterial growth, appendix plays a very important role in maintaining and protecting intestinal symbiotic flora. Appendectomy will lead to intestinal microecological disorders. Therefore, we put forward the hypothesis that "appendectomy leads to intestinal microecological disorders and then increases the risk of colorectal cancer". In this study, the feces of normal controls, appendectomy and patients with colorectal cancer were collected, and the specific changes of intestinal flora after appendectomy were explored in detail from the level of family, genus and species by macrogenomic sequencing. Then through functional gene analysis, metabolic pathway analysis and other methods to explore the molecular mechanism of colorectal cancer risk changes and the changes of microflora involved, and verified by mouse fecal bacteria transplantation animal experiment.

The NICE study is a prospective, multi-site study to train and validate a blood-based, glycoproteomic test for the early detection of advanced adenoma and colorectal cancer by collecting blood samples and associated relevant clinical information from average-risk participants who undergo routine screening colonoscopy as well as participants undergoing colonoscopy for surveillance or diagnostic indications

This is a phase 2 study to evaluate multiple doses of AK001 across 2 active doses. Pharmacodynamic activity will also be evaluated.

To evaluate the survival benefit of pre-operation chemotherapy of primary tumor tesection (PTR) compared upfront PTR for colorectal cancer (CRC) patients with an asymptomatic resectable primary tumor and synchronous unresectable liver-limited metastases with conversion therapy intent.

Despite advances in surgical care, the incidence of postoperative complications and prolonged recovery following colorectal surgery remains high. Efforts to improve the recovery process have primarily focused on the intraoperative (eg, minimally invasive surgery, afferent neural blockade) and post-operative periods (eg, "fast track" early nutrition and mobilization. The pre-operative period may in fact be a better time to intervene in the factors that contribute to recovery. The process of enhancing functional capacity of the individual in anticipation of an upcoming stressor has been termed "prehabilitation". Based on the notion that preoperative exercise would have an impact on recovery of functional capacity after colorectal surgery, our group recently conducted a randomized controlled trial. Subgroup analysis identified that patients whose functional exercise capacity improved preoperatively, regardless of exercise technique, recovered well in the postoperative period. However, one-third of patients deteriorated preoperatively despite the exercise regimen, and these patients were also at greater risk for prolonged recovery after surgery. These results suggested that exercise alone is not sufficient to attenuate the stress response in all patients. In the present trial, the impact of a multimodal prehabilitation intervention composed of exercise, nutritional supplement and psychological well-being begun in the preoperative period will be compared to one begun in the postoperative period.

Background: Laparoscopic colorectal surgery has been shown by randomized trials to be associated with better short-term clinical outcomes when compared with open surgery. However, in a traditional perioperative care setting, the reduction in hospital stay following laparoscopic surgery in these trials was modest. Fast-track perioperative programs have been introduced in the West to optimize perioperative factors to reduce the physiological/psychological stress of open colorectal surgery. However, few studies have evaluated the impact of fast-track programs on the outcomes after laparoscopic colorectal surgery. Objective: To compare the clinical and immunological outcomes of Hong Kong Chinese patients undergoing laparoscopic surgery for colorectal cancer with a "traditional" vs. a "fast-track" perioperative program. Design: Prospective randomized trial. Subjects: One hundred and twenty-eight consecutive patients undergoing elective laparoscopic resection of non-metastatic colonic and upper rectal cancer will be recruited. Interventions: Patients will be randomized to a "traditional" or a "fast-track" perioperative program. Outcome measures: Primary outcome: total postoperative hospital stay, including hospital stay of patients who are readmitted within 30 days after surgery. Secondary outcomes: immunological parameters (including systemic cytokine response and cell-mediated immune function), morbidity and mortality, quality of life, and medical costs.

Capecitabine, oxaliplatin, irinotecan and bevacizumab as perioperative strategy of borderline and/or high risk resectable colorectal cancer liver metastases

The purpose of this study is to evaluate the dose-limiting toxicity (DLT), toxicity profile, maximum tolerated dose (MTD) and characterize the pharmacokinetics of biweekly PEP02 treatment.

The purpose of this study is to investigate which oxaliplatie based adjuvant method (8 cycles or 12 cycles) is better for patients receiving curative colorectal cancer resection.
