Filter by:The goal of this observational study is to construct a multimodal intelligent model to predict the risk of heterochronous metastasis of rectal cancer, which is helpful for individualized diagnosis and treatment and follow-up planning. The main questions it aims to answer are: - what are the independent risk factors of distant metastasis (DM) in locally advanced rectal cancer (LARC) - What is the influence weight of the above factors on the heterochronous metastasis of LARC, and how to build a risk-prediction model This study will not affect or interfere with the routine medical diagnosis and treatment of participants, and will not increase the cost and risk of participants. Participant's information is protected and identified by a unique code.
Introduction: In locally advanced rectal cancers (LARC), TNM staging is far from optimal. We aimed to investigate the value of previously described circulating biomarkers as predictors of prognosis. Methods: Retrospective analysis of 245 LARC patients diagnosed between January 2010 and December 2022, who underwent neoadjuvant chemoradiotherapy and surgery at two centers. A Cox regression and Kaplan-Meier analysis were performed.
The intention of the study is to explore metabolic and inflammatory parameters in the pelvis and systemically after abdominoperineal resection (APR) for locally advanced rectal cancer (LARC) in patients that have received radiation therapy before surgery. In this study the inflammatory response after laparoscopic robot-assisted APR for LARC will be compared to results obtained in a recent cohort of patients operated with open APR for LARC, which will serve as the control population.
The use of chemoradiotherapy (CRT), in combination with surgery is the standard of care in the treatment of locally advanced rectal cancer. However some patients don't respond well to radiation. More advanced radiotherapy techniques, that result in fewer toxicities, means that we are now able to combine new anti-cancer agents into standard treatment. Targeting the tumour early in this way has the potential to improve response rates. Enadenotucirev is a specific type of anti-cancer virus that only targets cancer cells. It acts in the same way as any virus and can only survive by replicating inside cancer cells and not normal, non-cancerous cells. This means that it can selectively target and destroy tumours, without directly affecting normal cells. It also has the ability to attract cells from the body's immune system to help fight the cancer. The addition of enadenotucirev to standard chemoradiotherapy treatment may have a combined effect on the cancer cells with potentially few, additional side effects. This trial aims to determine the optimal dose and frequency of the virus to give by gradually increasing the number of doses each successive patient receives, and then increasing the dose of the virus itself. Each patient will receive a minimum of 3 doses, up to a maximum of 6, spread over the course of their 5 week standard chemoradiotherapy treatment. Patients will be closely monitored at all times to ensure that with each dosing group, there aren't excessive side effects. Patients will then undergo surgery as part of their standard of care and be followed up for up to 4-6 weeks post-surgery. This trial aims to determine the optimal dose and frequency that can then be used in future studies with the possibility of exploring the addition of Enadenotucirev to other chemoradiotherapy treatments.
The main purpose of the study was to define maximum tolerated dose (MTD), recommended Phase II dose (RP2D) safety and tolerability of Peposertib in combination with capecitabine and radiotherapy (RT).
This study aims to investigate the feasibility, safety and efficacy of triplet regimen of neoadjuvant chemotherapy in patients with locally advanced rectal cancer
The intention of the study is to explore metabolic and inflammatory parameters in the pelvis after abdominoperineal resection for locally advanced rectal cancer in patients that have received radiation therapy before surgery.
This study plans to construct a MR radiomics model for predicting pathological complete response(pCR) to neoadjuvant chemoradiotherapy(CRT) in locally advanced rectal cancer(LARC) patients.
The current trial is evaluating the impact of deep regional hyperthermia on the pathological complete response rate in locally advanced rectal cancer in the context of preoperative 5FU based radiochemotherapy.
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 1. Interval exercise training will maintain or improve fitness (measured by anaerobic threshold) in patients undergoing neoadjuvant chemoradiotherapy. 2. Interval exercise training is safe and feasible in patients undergoing neoadjuvant chemoradiotherapy awaiting rectal cancer resection. 3. Interval exercise training will improve other measures of physical fitness measured in the CPET and the oxygen uptake kinetics test. 4. Interval exercise training will improve quality of life in patients undergoing neoadjuvant chemoradiotherapy. 5. Improvements in physical fitness will reduce postoperative complications following major rectal cancer surgery. 6. 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? 7. Can we find an optimal time for surgery when fitness and cancer downstaging are at their best? HYPOTHESIS for Mechanism Pilot Study 1. To explore the exponential rate constant of post-exercise phosphocreatine recovery. 2. To explore the alteration in cellular and mitochondrial energetics eg. Change in mitochondrial numbers, change in mitochondrial activity and respiration.
