An RCT for the Effect of Biofeedback Therapy the Prevention of AR Syndrome in Rectal Cancer Patients...

Rectal Cancer

In patients who underwent sphincter preserving surgery with toal mesorectal excision and diverting stoma after neoadjuvant chemoradiation therapy for rectal cancer, the inestigators would evaluate the effect of a biofeedback therpy before stoma closure on their anorectal function after stoma closure.

Prospective Study in Pelvic Radiotherapy Patients

GynaecologicalUrological or Rectal Cancer

Symptoms such as diarrhoea and abdominal discomfort are common side effects of radiotherapy for tumours in the pelvis and usually occur within 2 weeks of starting treatment. Once the course of radiotherapy has been completed these symptoms usually subside, but in some patients they may continue and sometimes cause significant problems. It is not clear what processes are occurring to trigger such symptoms. There are a number of possibilities and we would like to investigate these further. If we can identify specific reasons for symptoms being worse in one patient compared to another, then we can try to either prevent or treat these. The aim of this study is to look for differences in the way that the bowel adapts to radiotherapy in patients who do and those who don't experience bowel symptoms during their course of radiotherapy.

Serial Endoscopic Surveillance & Direct Topical Antibiotics to Define the Role of Microbes in Anastomotic...

Anastomotic LeakRectal Cancer

Rationale: The surgical complication of intestinal anastomotic leak remains a clear and present danger to patients despite advances in surgical technique and ever more powerful antibiotics. No surgeon is immune from this complication and leak rates have not changed in decades. The consequences of a leak (peritonitis, sepsis, death) can be so severe that in the case of rectal cancer, diverting ileostomies are routinely performed to divert the fecal stream away from the healing anastomosis. We have recently discovered that certain intestinal bacteria, with the capacity to express collagenase and cleave MMP9 (Matrix metallopeptidase 9) to its active collagen degrading form, play a key and causative role in anastomotic leak. These bacteria often escape elimination due to the failure of current antibiotic regimens and their delivery methods to remain functionally durable at anastomotic tissue sites. Purpose: This phase II clinical trial will track, in real time, the process of anastomotic healing and its associated microbiome by performing serial endoscopic surveillance (SES) following rectal cancer resection. By capturing anastomotic images and the associated microbial and inflammatory mediators from anastomotic fluids via SES performed at three time points following rectal cancer resection, we will correlate healing to microbial composition and inflammatory mediator status. Patients will be randomized and, at each time point, will receive lavage of their anastomosis with either saline or a triple antibiotic solution (ciprofloxacin, metronidazole, neomycin). An anastomotic healing score captured during SES will be compared between the two treatment arms and correlated to microbial and inflammatory mediator analyses of fluid samples to determine how intestinal microbes influence the process of anastomotic healing.

Non-resectable Metastatic Cancer of the LungNon-resectable Metastatic Cancer of the Colon6 more

Reflexion on the therapeutic strategies to implement in patients at the end of life is advancing rapidly in France. However, beyond the choices presented to patients, sometimes even the decision to carry on, to limit or to stop treatments is also questioned. This decision is subjective; it is influenced by the patient's representation system (emotions, beliefs, values, practices, etc). In addition, even though he or she is the focus of the decision, the patient is not alone; other actors, accompanying the patient, play an important role in the final decision making. These actors, namely the doctors and close relatives, are also influenced in their decision making. This coexistence of representation systems may interfere with objective indicators that help in decision making (functional, clinical and biological) or with the knowledge acquired by doctors in their training and may complicate the decision-making process.

Validation of MMS Test for Cancer Monitoring

Colo-rectal CancerStomach Cancer2 more

The purpose of this study is the validation of MMS test to detect active tumor growth in different cancer types before and after therapy, as well as in the course of therapy and for subsequent relapse control compared to standard methods (clinical examination, imaging, tumor markers). It should be consider whether the MMS test has comparable diagnostic accuracy, and thus can replace more expensive or invasive procedures in future.

Evaluation of Rectal Cancer Treatment Response Using PET/MRI

Rectal Adenocarcinoma

The investigators will be using the combination of FDG-PET and multiparametric MRI in pre- and post-adjuvant chemoradiation therapy in order to attempt to predict pathologic response on surgical resection.

Quality of Life in Patients With Rectal Cancer Receiving Total Mesorectal Excision With or Without...

Rectal Cancer

The goal is to evaluate whether the renunciation of a diverting stoma in patients with adjuvant chemotherapy after low anterior resection with total mesorectal excision (TME) and neoadjuvant chemoradiotherapy leads to a better quality of life without increasing morbidity and mortality in patients with rectal cancer.

A LAparoscopic and TransAnal Total Mesorectal Excision (TME) for Rectal Cancer Trial

Colorectal Neoplasm

All patients planned for an anterior resection due to rectal cancer with a total mesorectal excision are included. This is a feasibility study, thus no randomization will be performed. Primary endpoint is clinical and pathologic examination of the specimen. Secondary end-points include clinical variables such as conversion rate, re-admission and/or re-operation due to any complication and health economy analyses.

Locally Advanced Rectal Cancer

Research project for patients with locally advanced rectal cancer in which biological material and health-related personal data are collected. The aim is to investigate if an additional method (liquid biopsies) can predict the response after chemo-radiotherapy and before surgery.
