Active clinical trials for "Colonic Neoplasms"

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 Sweden, approximately 43,000 people have undergone surgery with ileo-, colo- or urostomy. The most common type of stomy is a sigmoidostomy. A large proportion, about 50%, of patients who receive a permanent sigmoidostomy develop a parastomal hernia which may have major impact. There are indications that specific abdominal exercise may reduce the risk of parastomal hernias, but randomized studies are lacking. The aims of the study are: to evaluate the effect of specific exercise to counteract the development of parastomal hernia in sigmoidostomy and the hernia's impact on ostomy function, physical function and quality of life. to examine patients' experience of living with parastomal hernia. The study plans to include 240 patients who on will undergo surgery and receive a sigmoidostomy. These will be randomized to receive only advice according to the usual routine to avoid the development of parastomal hernia or these advice with the addition of specific abdominal muscle training. The training is initiated before the operation and is then carried out during the first postoperative year. Follow-up will be done with a clinical assessment and with measurement of bulge and size of the parastomal hernia manually, with electronic measuring equipment and via computed tomography images. Patients will assess their stoma and stoma function and assess any discomfort and its consequences of hernia via a study-specific questionnaire. Type of ostomy bandage will also be registered. The evaluation will be carried out 6, 12 and 36 months postoperatively. Prior to the start of sub-study a, the planned measurement methods to assess whether a parastomal hernia is present will be tested for validity. In addition, a group of patients (≥15 people) with parastomal hernia will be included in a qualitative sub-study where they will be interviewed about their experiences of the hernia hernia and how it may affect daily life. The present study will be able to answer whether specific exercise can reduce the risk of parastomal hernia. Methods for clinically assessing and evaluating bulging and hernias will be tested and evaluated in relation to patient-reported symptoms. In addition, the study will provide information about the patient's experience of having a parastomal hernia and how it affects daily life and physical activity. The results will provide an increased understanding of parastomal hernias, which may change the follow-up of patients in the future.

The goal of this clinical trial is to evaluate the diagnostic potential of Artificial Intelligence-assisted Fecal Microbiome Testing for the diagnosis of colon cancer. The main question it aims to answer is: • Is Artificial Intelligence-assisted Fecal Microbiome Testing a reliable screening test for colon cancer? Participants will be asked to provide fecal samples to be analyzed with next-generation sequencing techniques. If there is a comparison group: Researchers will compare the diagnostic performance of AI-assisted Fecal Microbiome Testing with colonoscopy to see the correlation between the results of both interventions.

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.

Recently, the use of mobile health is increasing for the purpose of managing prognosis such as recurrence, survival and quality of life by using a wearable smart band and a smartphone application. In the era of the 4th revolution, mobile health for the purpose of comprehensive prognosis for cancer patients is becoming a very good tool. It is possible to confirm the clinical significance of short-term and temporary health care through a mobile application and a smart band during the treatment process for cancer patients, but the study is insufficient to generalize the number of subjects. Therefore, for colon cancer patients who need prognosis management after surgery, we will investigate the effect of a mobile application using a smart band which has a modular structure reflecting the treatment method and treatment process after surgery. This study targets patients who underwent prostate cancer surgery. An intervention group (App+IoT device) uses a smart care application for 12 months. This application was tailored for prostate cancer patients and created by reflecting the treatment process after surgery. And they also uses a wearable smart band for 12 months. Control group is provided general education through the hospital brochure. Evaluation will be conducted 2-3days after surgery (before discharge), and at 1, 3, 6, and 12 months after surgery.

By joining this study, participants, including patients and their caregivers, will be provided useful information about colon cancer that may help alleviate anxiety surrounding treatment, improve communications with the medical team, and identify practical ways to support each other. Participating in this study will have no impact on your cancer care that participants receive from your provider. It is expected that the resources provided to participants and participants caregiver will help improve participants overall care. The study team will provide computer tablets for patients and their caregivers to use as part of the study to access information about colon cancer and how to help manage participants therapeutic care. The study team will check-in each week to provide assistance with the use of the tablets and ask the patient and their caregiver, to complete an assessment survey. As part of the surveys the study team will collect participants full name, address and phone number and some basic information about participants (e.g., age, gender and race). The study team will also collect some personal or medical information, including the stage of colon cancer and treatment received (if the participant) or your relationship to the patient if participants caregiver. The study team will also collect some information on your emotional health and views about the medical care that has been provided to date from the questionnaire. All this information will be held confidential and not forwarded to anyone outside of the study personnel. There are no activities required, except that the study team will encourage caregivers and patients to discuss and use the information provided in computer tablets to enhance their cancer care. Whether or not the participants use this information will not affect their ability to receive high-quality care from their providers. There is a slight burden of responding to the survey questions used to help us understand the useful features of this program. For this reason, the investigator has included small incentives to support the time and effort needed to complete these survey assessments. The study team hopes that this study, one of the first of its kind, will help identify the resources and methods that can be used to help patients and caregivers have a better understanding of their cancer care and provide resources that they can use to enhance the effectiveness of their therapy.

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.

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 study seeks to learn more about the vitamin D receptor and its relationship to colon cancer. The Vitamin D receptor is found in colon cancer cells. When Vitamin D binds to the receptor in the cancer cells, it may stop cancer cells from growing abnormally and may cause cancer cell death. Vitamin D has been used in other research studies and information from those other research studies suggests that Vitamin D may help in the treatment of colon cancer. Participants will receive either high-dose vitamin D or standard-dose vitamin D. The study drug will be given 14-28 days prior to your surgery. The number of days will depend on when the surgery is scheduled.

The main objectives of this single-arm pilot trial are to investigate the feasibility of our protocol in terms of 1) recruitment, 2) adherence, 3) tolerability, 4) acceptability and 5) retention. We aim to recruit 20 participants with advanced colon cancer (stage 3-4) who will have assessments of their autonomic nervous system function, carcinoembryonic antigen (CEA) levels, and patient-reported outcomes. Thereafter, patients will be directed to a nearby field clinic to receive twice-weekly cervical assessments & high-velocity, low-amplitude (HVLA) cervical adjustments for a period of 6 weeks. Re-assessments will be performed following 2 weeks and 6 weeks of chiropractic care.
