Active clinical trials for "Rectal Neoplasms"

Main objective: To evaluate the bidirectional relationships between physical exercise and sleep parameters, as a part of multimodal prehabilitation intervention, on pre- and postoperative outcomes in surgical patients with colorectal cancer, in an RCT. Secondary objective: to determine whether the levels of anxiety and depression affect these relationships. Objectives are based on the overarching hypothesis that is sleep and physical activity influence each other through complex, reciprocal interactions including multiple physiological and psychological pathways. To achieve this, providing a multimodal prehabilitation, specifically physical exercise, involved in mental and physical health through different mechanisms, i.e., improving physical functioning and fitness, reducing side effects of cancer treatments, preventing bone loss and weight gain, improving the quality of life and sleep, decreasing symptoms of fatigue and depression. The present is a pilot study aiming to evaluate the bidirectional relationships between sleep and physical exercise, and the preliminary outcome has important implications for informing both clinical and public health practice. Research question: Does a multimodal intervention including physical exercise improve sleep quality and duration compared to standard of care, during the perioperative period? Conversely, does a better sleep quality and duration increases the level of physical exercise during the perioperative period? How the level of anxiety and depression will affect these relationships? If the Prehabilitation program specifically physical exercise will positively affect sleep quality and duration after surgery, in the way to be a protective factor of sleep to not be reduced by up to 55% compared to those receiving standard of care?

It is a multicenter, prospective, and randomized controlled clinical study of patients with mid- or low- rectal cancer who received laparoscopic TME surgery aims to explore whether the application of near infrared-indocyanine green imaging system can evaluate the anastomotic blood perfusion accurately, and optimize the surgical procedures, or even reduce the incidence rates of postoperative anastomotic leakage in mid- or low- rectal cancer patients.

Colorectal cancer arises from the mucosal layer of the colon. Current screening is performed by flexible endoscopy, which involves visual inspection of the mucosal lining of the colon and rectum with an optical camera mounted on the endoscope, with abnormal areas being biopsied. This method is somewhat limited in that there are no readily available surface pattern or morphological classification systems with adequate sensitivity or specificity to evaluate extent of submucosal invasion (deep, superficial, or none). Optical coherence tomography (OCT) using pattern recognition is a high-resolution imaging modality. There is currently an unmet need to predict depth of invasion for colonic tumors to decide on applicability of endoscopic (endoscopic submucosal dissection or endoscopic mucosal resection) vs. surgical therapy. The investigators' hypothesis is that OCT will have a higher diagnostic accuracy for determining depth of submucosal invasion compared to existing modalities. The investigators will first aim to assess the procedural feasibility and safety of using an OCT probe during routine colonoscopy with an early feasibility study. This study will identify appropriate modifications to the device and help with development of subsequent clinical study protocols. The eventual goal is to assess the diagnostic accuracy of OCT imaging for predicting depth of invasion of colonic tumors.

In patients operated for colorectal cancer, pain, anxiety and depression are important factors in postoperative rehabilitation. The use of new technologies, as virtual reality immersion, could further improve their postoperative management. To date, no study has evaluated the potential benefits of using virtual reality before and after colorectal cancer surgery. The main objective is to determine if virtual reality can reduce postoperative anxiety in patients undergoing colorectal cancer surgery. To answer this question, the investigators plan to execute a randomized controlled, single-center, open-label, superiority interventional trial. Patients will be randomized into 2 parallel arms: 1 interventional "virtual immersion" arm and 1 "control" arm. Patients with colorectal cancer, regardless of oncological stage, or a colorectal lesion deemed endoscopically unresectable, with an indication for elective surgical management by laparotomy or laparoscopy will be included. For patients in the interventional arm, virtual reality headset is put on the day before the operation and in the morning just before going down to the operating theatre. Colorectal cancer surgery then proceeds as usual. In the postoperative period, virtual reality sessions are offered every day and on request without any limit in number. Virtual reality immersion offers a visual and auditory experience during a soothing journey through visual worlds filmed in natural environments. This is a purely contemplative mode, lasting maximum 30 minutes. For the control arm, patients are treated according to the usual practices of the department and do not have access to virtual reality. The main purpose is to show a greater decrease in anxiety in the interventional group by measuring the absolute difference between the State-Trait Anxiety Inventory scores before surgery and at discharge.

The use of immune checkpoint inhibitors (ICIs), alone or in combination with other cancer treatments is increasing dramatically with immune-related adverse events (irAEs) common (90%) during ICI treatment. Most irAEs are symptomatic and symptom self-management with timely reporting of moderate or severe symptoms to health care providers (HCPs) may reduce irAE severity by early recognition and management, resulting in fewer treatment interruptions and unscheduled health services.

Benefits of physical activity (PA) as supportive care in cancer have been widely demonstrated by the scientific community. However, survivors who have completed chemo-radio-immunotherapy treatments doesn't achieve PA recommendations on average. This reinforces the need to identify factors influencing PA level, and to propose a multilevel model (macro-, meso-, micro-level) to understand better what facilitates the adoption and maintenance of active behaviour and what hinders it. To date, there is no ecological model in France explaining this behaviour in the post-treatment phase of breast, colorectal, prostate, and lung cancers. From this initial model, we seek to design an educational and motivational intervention in PA. Thus, the investigators propose to test the feasibility of implementing an individualized program to increase and maintain level of physical activity and to decrease sedentary behaviours in physically inactive cancer survivors. This program is based through and identification of barriers and facilitators of an active lifestyle among this population.

The objective of the study is to assess the safety and technical feasibility of a new imaging system, used during colorectal resection surgery, named Trident in version 1.0, which could be used by the surgeon during colorectal procedures to obtain information on intestinal tissue oxygenation.

This phase II trial studies how well time-restricted eating works in reducing side effects of radiation or chemoradiation side effects when compared to nutritional counseling among patients with prostate, cervical, and rectal cancers. Time-restricted eating, also called short term fasting or intermittent fasting, is an eating plan that alternates between not eating food (fasting) and non-fasting periods. Nutritional counseling involves being asked to follow a healthy, balanced diet that includes instructions on what kinds of food are better tolerated during radiation and chemoradiation therapy. This trial may help researchers determine if certain diets may improve the anti-cancer effects of radiation therapy and reduce the side-effects of this treatment. If successful, these diets may be integrated into the future treatment of prostate, cervical, and rectal cancers.

The goal of this clinical trial is to quantify the effects of aerobic exercise training compared to attention control on intermuscular adipose tissue in colorectal cancer survivors.

This trial (molecular characterization trial) focuses on rectal cancer, a common cancer that is treated with radiotherapy (RT) as standard of care and represents a setting in which to study the effects of RT on the immune system.
