Active clinical trials for "Colorectal Neoplasms"

The goal of this research study to help develop a tool to assist patients in making decisions about care during treatment for colorectal cancer. Information collected during this study will be saved to help develop future studies about patient decision making in cancer treatment.

Previous studies have shown that colorectal cancer patients' prognosis and overall survival was related with immune cell expression in patients' tissue. However, the circulating immune cell activity changes in patients' blood has few studies. The purpose of this study is to analyze the variation of circulating immune cell activity in colorectal patients' blood which is classed as clinical staging.

Cancer treatments have successfully improved cancer outcomes but frequently negatively impact quality of life in cancer survivors. In particular, chemotherapy (CTX) has been associated with impaired cognitive abilities such as concentration and memory. The goal is to investigate the neural mechanisms of chemotherapy-related cognitive impairment (CRCI) using an interdisciplinary translational approach. Previous research in this area lacks diversity in studied cancer populations and treatments focusing primarily on breast cancer and provides limited understanding of how CRCI emerges from changes in neural structure, function, and connectivity. To overcome these limitations, this feasibility/pilot study aims to investigate CRCI in patients with colorectal cancer (CRC).

A retrospective cohort study was conducted from 2016-18 in a single busy district general hospital providing services to a population of 700,000 people. In the study, patients with true IDA (low MCV and ferritin) were found to be more likely to have Colorectal cancer compared to any other type of anaemia which confirmed the latest guidelines for management of IDA. Compared to symptoms, only the presence of a mass on abdominal examination and rectal examination was found to be more likely associated with cancer.

Intraoperatively, the surgeon will interrogate the liver with ultrasound. The time spent by the surgeon using the ultrasound is recorded. If all lesions seen on pre-op imaging were found, the patient does not have the Pathfinder Explorer system applied. If one or more lesions cannot be found, then the Pathfinder Explorer system is calibrated and a tracking device is attached to the ultrasound probe, which the surgeon will use to reattempt localization of the missing tumor. The Pathfinder Explorer system operates in real-time in conjunction with the ultrasound.

This research clinical trial studies high definition single cell analysis in blood and tissue samples from patients with colorectal cancer which has spread to the liver. High definition single cell analysis allows doctors to study the properties of cancer cells that are sometimes found in the blood of patients and to determine how the genes and proteins in them may change over time. Studying samples from patients with colorectal cancer in the laboratory may help doctors learn more about how cancer spreads, as well as how to predict the disease outcomes in patients with cancer.

The purpose of this study is to understand the patient experience with an adverse event after surgery. An adverse event is an undesirable experience or complication associated with your surgery.

Given a context where patients autonomy respect is important, it is necessary to pay a sustained attention to the patients care and life experiences, as well as the families and relatives of patients with colorectal cancer or patients in remission of colorectal cancer. Thanks to families and relatives data, it will allow to improve the analyses carried out by the "Societal Cancer Observatory" in 2016.

Patients diagnosed with T4 colorectal cancer represent a specific subgroup of colorectal patients, frequently composed of fragile patients whose advanced nature of the disease often requires a multi organ resection by an open surgery approach and frequently leads to higher intra/postoperative complication.Those characteristics makes them to be considered less suitable for ERAS protocol, especially regarding an expected difficult compliance to postoperative items. The impact of enhanced recovery program on postoperative outcomes in this subset of patients has never been addressed in literature, in fact most of studies either excluded T4 patients due to higher rates of complication or adopted an homogeneous patient sampling analizing all stage colorectal cancer together. Our aim is to investigate the feasibility of ERAS protocol in T4 colorectal patient, primary outcome was to compare postoperative lenght of stay between T4 colorectal patients treated with ERAS protcol and those treated with standard of care.

To compare the prognosis of elderly patients undergoing radical resection of colorectal cancer treated with general anesthesia and general anesthesia combined with transversus abdominis plane block and continuous infusion of dexmedetomidine. The incidence of postoperative delirium, postoperative acute pain moderately to severely and poor postoperative recovery were composite endpoints to determine the prognosis of patients.
