Active clinical trials for "Rectal Neoplasms"

This 12-week, exercise study will assess the feasibility of a home-based high-intensity interval training (HIIT) program among colorectal cancer survivors and explore the impact of home-based HIIT compared to a standard home-based moderate-intensity continuous aerobic exercise program on physical outcomes linked with survival from colorectal cancer and surrogate blood markers of colorectal cancer recurrence. HIIT is a type of aerobic exercise that includes short bursts (i.e. 1-4 minutes) of vigorous exercise followed by longer periods of moderate to lower intensity exercise (i.e. 1-10 minutes). Participants in this study will be randomly assigned into a personalized home based exercise program - either high-intensity interval training (HIIT) or moderate-intensity continuous aerobic exercise (MICE). This pilot study will provide us with preliminary evidence for a larger trial aimed to compare the effectiveness of these two different types of home-based exercise programs on physical outcomes linked with survival, quality of life, and surrogate blood markers of colorectal cancer recurrence.

This research project addresses critical gaps in cancer symptom management through the creation of a mobile chemotherapy symptom management application. This application will assess for the presence and severity of common chemotherapy side-effects and provide personally tailored symptom-related video and narratives to enhance self-management of cancer and treatment-related symptoms. This study will examine patient acceptance and use of this mHealth application (called MyChemoCare) in a prospective trial of cancer patients (n=60) who are receiving chemotherapy for colorectal cancer at the University of Michigan Comprehensive Cancer Center.

Anastomotic leak (AL) is a breakdown of a suture line in a surgical anastomosis with a subsequent leakage of the luminal content. Anastomotic leakage occurs commonly in rectal and esophageal anastomosis than the other parts of the alimentary tract due to technical difficulties in accessing these areas and their easily compromised blood supply. Anastomotic leakage is the most feared complication following rectal resection and anastomosis. The incidence of anastomotic leakage ranges from 2.8% to more than 15%, with mortality rate more than 30%. Subclinical anastomotic failure may occur in up to 51% of patients. Anastomotic leakage leads to increase the rate of secondary interventions, re-operations, longer postoperative hospital stay, increased cost, and major impact on the patient's quality of life. In the medium to long term, patient may be unfit for post-operative adjuvant therapy with decreased the disease survival. Furthermore anastomotic leakage itself may increase the local recurrence, a reduction in overall survival, and a large proportion of patients are left with a permanent stoma.

The purpose of this study is to demonstrate that NIR fluorescence angiography using the PINPOINT Endoscopic Fluorescence Imaging System ("PINPOINT System" or "PINPOINT") can assess viability of colon tissue during laparoscopic left colectomy. This information will provide the surgeon with clinically relevant information in assessing whether or not the tissue has adequate blood supply in the lower section of the colon prior to a colectomy.

There is a critical need for physical activity interventions in colorectal cancer (CRC). The investigators have developed a digital health physical activity intervention, Smart Pace, which includes a wearable tracker (Fitbit) and text messaging and aims to have patients build up to 150 min/wk of moderate activity. In this study, the investigators propose to expand and improve Smart Pace, including: 1) enrolling patients during chemotherapy; 2) tailoring text messages to individual preferences and treatment timing; and 3) adding resources to support home-based exercise. The study is a 12-week pilot randomized controlled trial (RCT) to evaluate the feasibility of this novel digital health physical activity intervention among 48 CRC patients on chemotherapy. The specific aims are to: 1) Determine the feasibility of the intervention via adherence and attrition, and determine the acceptability of the intervention via questionnaires and semi-structured interviews . 2) Estimate the effect of the intervention vs. usual care on physical activity, QOL, and symptoms at 12-weeks . And 3) Explore the impact of the intervention vs. usual care on fitness, weight, waist circumference, and blood pressure at 12-weeks.

This study is designed to investigate if aerobic exercise during and after neoadjuvant chemoradiotherapy (NACRT) can improve outcomes for rectal cancer patients.

With an increasing number of rectal cancer (RC) survivors, we see a rising attention to the late adverse effects following treatment of RC. Late adverse effects that are highly prevalent and negatively impact patients' symptom burden and quality of life are: bowel-, urological and sexual dysfunctions; psychological distress; fear of recurrence. The current follow-up program primarily focuses on detection of recurrence, with less attention to late adverse effects. In a patient-led follow-up program, the surveillance for recurrent disease is combined with detection and treatment of late adverse effects and supportive survivorship care. The follow-up involves a high degree of patient-involvement, aiming at meeting the individual patient's needs. The patient-led follow-up programme is based on a standardized patient-education in order to enforce the patients to assess and respond sufficiently to symptoms and health problems. In case of symptoms and concerns, the patients are instructed to consult a health professional for adequate assistance and intervention. The intervention is tested in a multicenter randomized trial, comparing the patient-led follow-up to standard routine follow-up, involving prescheduled outpatient visits.

RATIONALE: Octreotide may be effective in preventing or controlling diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer. It is not yet known whether octreotide is effective in treating diarrhea. PURPOSE: This randomized phase III trial is studying octreotide in preventing or reducing diarrhea in patients who are undergoing chemoradiotherapy for anal or rectal cancer.

The present study is a randomised control trial investigating the effects of a short six week exercise training program in rectal cancer patients following neoadjuvant chemoradiotherapy prior to elective rectal cancer surgery. Twelve patients will be randomised (1:1) to an intervention and a control group. The patients randomized to the intervention group will attend a total of 18 tailored exercise sessions (Three 40 minute sessions for six weeks) after their 6 weeks of chemoradiotherapy treatment. Where possible the exercise training sessions will be arranged to fit in with other appointments at the hospital. Patients randomized to the control group will be unsupervised. They will only attend an extra 3 sessions were a cardiopulmonary exercise test and VO2 Kinetics test will be performed. Patients will also be invited to attend 3 health related quality of life interviews at week 0, 3 and 6 during their exercise programme. These appointments will be directly before or after their exercise sessions to minimise hospital attendence. Following surgery only routine clinically relevant observational data will be collected. These data will relate to hospital length of stay, the level of care required following surgery, post-operative morbidity survey (POMS) and the recovery process. Most of this information can be accessed from patient notes and on the electronic patient records system. This is a subgroup RCT of patients in a larger interventional trial (6 control and 6 exercise intervention patients) will be asked to consent separately for the the 31-Phosphorus Magnetic Resonance Spectroscopy (31P MRS) scans and the blood samples. HYPOTHESIS Interval exercise training will maintain or improve fitness (measured by anaerobic threshold) in patients undergoing neoadjuvant chemoradiotherapy. Interval exercise training is safe and feasible in patients undergoing neoadjuvant chemoradiotherapy awaiting rectal cancer resection. Interval exercise training will improve other measures of physical fitness measured in the CPET and the oxygen uptake kinetics test. Interval exercise training will improve quality of life in patients undergoing neoadjuvant chemoradiotherapy. Improvements in physical fitness will reduce postoperative complications following major rectal cancer surgery. Does physical activity, measured by Sensewear Pro 3 activity monitors, decrease during neoadjuvant chemoradiotherapy and can this decrease be attenuated by an exercise training program? Can we find an optimal time for surgery when fitness and cancer downstaging are at their best? HYPOTHESIS for Mechanism Pilot Study To explore the exponential rate constant of post-exercise phosphocreatine recovery. To explore the alteration in cellular and mitochondrial energetics eg. Change in mitochondrial numbers, change in mitochondrial activity and respiration.

Sexual dysfunctions are well-recognized complications after rectal cancer surgery. Damage to the pelvic plexus and pelvic splanchnic nerves results in ejaculatory dysfunction. The purpose of this study is to evaluate the efficacy of Udenafil(Zydena®, Dong-A Pharmaceutical co., Ltd, Seoul, Korea) in penile rehabilitation for patients who undertake total mesorectal excision.
