Filter by:The intervention will be a physical exercise program for colorectal cancer patients during the adjuvant chemotherapy. The exercise program aims on reducing the side effects of the treatment and improving patients' quality of life. In addition, the investigators try to improve endurance and resistance training level, in order to achieve greater physical functionality, survival and general well-being. For this, the investigators will carry out an exercise program based mainly on muscular strength and cardiorespiratory condition. It will last 6 months, with a frequency of 3 days per week, including sessions of 60 minutes. Sessions will consist of three parts: warm-up, main part (endurance and resistance training), and cool down. An individualized and supervised progression of training will take place. The intensity levels will always be adjusted to the initial levels of the participants, always considering their preferences and comfort. Participants' preferences and exercise history will be considered through an initial interview. Motivational strategies based on self-determination theory will be applied, since it is one of the most used theories in the field of physical exercise. This theory proposes that all people need to feel competent, autonomous and socially related. If these three needs are satisfied, participants will develop more positive (autonomous) forms of motivation, which are related to better consequences such as vitality, enjoyment, quality of life and adherence to physical activity. In addition, motivational strategies will be applied for families and healthcare professionals. Before starting the program and at the end of it, each eligible patient will be evaluated through: - Physical activity: strength test of lower and upper limbs, agility test, stress test for cardiorespiratory fitness, physical activity levels, physical condition and body composition. - Psychological factors: autonomy support, basic psychological need satisfaction, motivation, quality of life, perceived barriers, depression, anxiety, hope, quality of life. - Clinical parameters: survival rate, side effects, biological factors, treatment delays and planned treatment completion.
This is a proof-of-concept pilot randomized clinical trial to test the feasibility of the innovative Patient-Reported Outcomes-Informed Symptom Management System (PRISMS) to enhance personalized supportive care for cancer patients and caregivers during post-treatment care transition.
Colorectal Carcinoma (CRC) is the third most frequent diagnosed cancer worldwide, with 1.4 million new cases every year. In an attempt to reduce this number many countries have implemented a nationwide screening programme targeted at detecting CRC in an early phase using fecal immunochemical tests (FITs). People with an elevated level of blood in their stool are offered a colonoscopy, an invasive medical procedure where CRCs and premalignant lesions (together also referred to as advanced neoplasia) can be detected accurately. However, the current screening method using FIT is not optimal. In FIT-based CRC screening studies, 1 in 4 participants with CRC and 2 in 3 participants with advanced neoplasia receive a negative FIT result. In contrast, an estimated 1 in 2 FIT-positives have advanced neoplasia at colonoscopy. Recent studies have demonstrated that a risk model that takes into account the FIT result and other risk factors for CRC could enhance the effectiveness of a FIT-based CRC screening programme. The objective of this study is to assess the yield of advanced neoplasia in the colon and rectum of a FIT-based risk model at colonoscopy, compared to that of a FIT-only CRC screening strategy. Our hypothesis is that a risk-based model yields significantly more advanced neoplasia at colonoscopy than the FIT by itself, and that it does not affect participation rate. To assess this hypothesis, the investigators have designed a clinical trial in which the investigators randomize 23,000 asymptomatic individuals between the age of 55 and 75 years old to either risk-based screening (intervention group) or FIT-only screening (control group). The intervention group will receive a questionnaire on risk factors of CRC (e.g. smoking, family history of CRC), and a FIT. The control group will only receive the FIT. The positivity threshold of the FIT in both groups will be set at 15 micrograms haemoglobin per gram faeces. The positivity threshold of the risk-based model in the intervention group will be set at 0.10 (out of a range of 0 to 1), a threshold that is calculated with a goal to match the positivity rate of the control group. Participants with a result that is above the thresholds of the FIT and/or the risk-based model will be invited to undergo a colonoscopy according protocol of the Dutch national screening program. After the study has ended, the investigators will compare both groups to assess our hypotheses.
Korean Americans report the lowest and declined rates of colorectal cancer (CRC) screening, compared to general population in the United States. The present study aimed to evaluate the efficacy of a community-based multifaceted intervention designed to improve CRC screening among Korean Americans.
Early detecting and removing of colorectal advanced adenomas can reduce incidence of colorectal cancer. Because of the less bleeding of advanced adenomas, the sensitivity of existing quantitative fecal immunochemical test (qFIT) is unsatisfying. A new technology qFIT, which have a higher sensitivity in extremely low concentration of hemoglobin compared with existing commercially available qFIT, is developed and this study will prove the high diagnostic accuracy in detecting colorectal advanced adenoma.
The primary objective of this sub-study is to obtain de-identified, clinically characterized, stool specimens from subjects with untreated solid tumors for research use in the development and validation of a stool-based test for colorectal cancer.
Establishing the genetic map of primary and secondary resistance of Chinese wild RAS colorectal cancer received anti-EGFR treatment through tissues and peripheral blood NGS testing. Combination genetic data with clinical characteristics, prognosis and treatment data to explore the molecular mechanism of resistance of anti-EGFR-antibody.
Rationale: Throughout the years, there has been a rapid change in the perioperative protocols and procedures surrounding colorectal surgery. Upon the introduction of the Enhanced Recovery After Surgery (ERAS) program in Western countries, an improvement in postoperative outcomes was seen. Nowadays, researchers focus on further improving the current standard ERAS programs enabling an accelerated version hereof. Objective: The aim of this study is to investigate the feasibility and safety of a 23-hour accelerated ERAS protocol (ERAS 2.0) for patients undergoing colorectal surgery compared to a retrospective cohort of patients who followed ERAS 1.0 for colorectal surgery. In this ERAS 2.0 protocol, patients undergoing colorectal surgery will be discharged within 23 hours after surgery. Study design: This study is an investigator-initiated, single-center prospective study. Study population: Patients aged ≥ 18 years ≤ 80 undergoing surgical resection for colorectal pathology that meet the eligibility criteria will be invited to participate in this study. Intervention: Adhering to a strict multidisciplinary and multifaceted ERAS 2.0 protocol, patients receiving elective colorectal surgery will be discharged 23-hours after surgery. Main study parameters/endpoints: Rate of the successful and safe application of the 23-hour accelerated ERAS 2.0 protocol for patients undergoing elective colorectal surgery. Success rate will be measured in readmission rate and safety will be measured with rate of serious adverse events (Clavien Dindo ≥3b). Success rate (feasibility) will also be measured in percentage of patients who were not able to be discharged 23 hours after 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.
Colorectal cancer is a leading cause of cancer-related morbidity and mortality. CRC-related death can be prevented through fecal occult blood test screening. Because of economic and high sensitivity, fecal immunochemical test is recommended for screening population of CRC. The purpose of this study is to compare the accuracy of 4 different fecal occult blood testing in medium and high risk screening population in Chinese.
