Active clinical trials for "Digestive System Neoplasms"

Chemotherapy with platinum salts is very emetic. The aim of this study is to evaluate the benefits of foot reflexology in nausea and vomiting induced by platinum salts-based chemotherapy in patients with thoracic or digestive tumors.

This pilot clinical trial studies how well consumer-based activity monitor works in evaluating and measuring activity of older patients with abdominal cancer undergoing surgery. Consumer-based activity monitor (CAM) may identify patients who are at-risk for increased post-surgery medical problems. With early identification of at-risk patients, CAM provide supervised exercise in the preoperative and postoperative periods to improve over mobility and potentially decrease preoperative complications among patients undergoing major abdominal surgery.

Patients with cancer often experience appetite loss and weight loss unintentionally. Rapid weight loss negatively impact on physical functioning, quality of life, and overall survival. Patients will be randomly assigned into two groups. An intervention with acupuncture may slow down or stop the progression of cancer-related anorexia and weight loss.

The hospital care of patients with cancerous pathology is part of a multidisciplinary care path that includes many stages. The treatment conditions in this course vary depending on the reasons that led to suspect the existence of a cancerous pathology: accidental discovery, screening, warning signs (sometimes expressed in an acute form) or referral for treatment in charge after the diagnosis has already been made. As soon as the patient presents to the hospital, various expertises are mobilized to establish the diagnosis, carry out the extension assessment and assess the comorbidities and conditions that may have an impact on the choice of treatments. During this initial evaluation, each file is evaluated in a Multidisciplinary Consultation Meeting to define the optimal therapeutic strategy which will often include several stages involving surgery, radiotherapy, medical oncology (chemotherapy, immunotherapy, targeted therapy, etc. hormone therapy), interventional radiology, and / or supportive oncological care (nutrition, pain treatment, correction of metabolic abnormalities, palliative care, etc.). This treatment path is considered to be very complex and the fluidity of its organization determines the processing times. The management of patients in a cancer department may vary depending on the organization specific to each hospital. The health crisis induced by the COVID-19 epidemic, associated with the containment measures put in place from March 19 to May 11, 2020, have limited the use of patients in hospitals, even for emergency activities. It has also led to a reorganization of scheduled activities within establishments, with a concentration of resources around unscheduled care, in particular COVID patients. In many establishments, the other activities were, for many, deprogrammed with postponed appointments. The impact of this epidemic on the hospital journey of patients with cancerous pathology is the subject of questions at the national level. The delays in diagnosis and treatment induced have possibly had an impact on the quality of the care and on the delays with, as a corollary, a possible loss of opportunity for the patient.

According to data from Global Cancer Statistics 2018, colorectal cancer (CRC) ranks second in incidence and fifth in mortality among all cancers in China. The underlying neoplastic progression from adenoma to CRC endures up to 10 years, providing an extended window for CRC detection and screening. Currently, fecal occult blood test (FOBT) and colonoscopy are the main diagnostic and screening methods for CRC in Chinese clinical practice. However, due to low patients' compliance with colonoscopy and poor sensitivity of FOBT, a large proportion of CRC could not be effectively diagnosed and treated at early stage. Therefore, noninvasive fecal DNA detection approach with enhanced performance is urgently needed in clinic. The aim of this trial is to evaluate effectiveness of the Human Multigene Methylation Detection Kit (Fluorescent PCR) for auxiliary diagnosis of colorectal cancer. By assessing the level of DNA methylation of certain genes in human stool, the test can indicate whether cancerous and precancerous lesions exist in the areas of colon and rectum.

This study is a prospective study where the investigators will make a database of all the patients who have received this procedure and will document various outcomes (i.e. number of sutures used, number of clips (if used), time required to close, complications/ issues). No changes will be done to the participant's procedure and the participants are asked to consent for the use of the participant's data in our database. The participants are being asked to be in this research study because the participants have been scheduled to undergo an ESD procedure at Baylor St. Luke Medical Center and will most likely require clipping and/or suturing following intervention. This study is important because this is a relatively new procedure; although it is a part of the participant's standard of care, it is not done in many hospitals. The investigators would like to document the outcomes and results of such procedures to continuously improve our standard of care.

This is a prospective registry of all patients who endoscopic submucosal dissection (ESD), per-oral endoscopic myotomy (POEM) and gastric per-oral endoscopic myotomy (G-POEM) using ConMed Electrosurgical unit for submucosal Dissection at Baylor St Luke's Medical Center. Collected information includes; procedure technical success rate, duration, periprocedural complications and ease of use.

General anaesthesia often reduces blood pressure whereby blood flow to the brain and other vital organs may become insufficient. Thus, medicine is often administered during anaesthesia to maintain blood pressure. However, it is unclear at what level blood pressure should be aimed at during anaesthesia. Several factors may affect blood flow to the brain during anaesthesia. During surgery on the internal organs, a hormone may be released that dilates blood vessels and causes a so-called mesenteric traction syndrome characterised by a decrease in blood pressure and flushing. This reaction lasts for approximately thirty minutes and is observed in about half of the patients who undergo surgery on the stomach and intestines. It is unknown whether a mesenteric traction syndrome affects blood flow to the brain. Ventilation is also of importance for blood flow to the brain. Thus, blood flow to the brain is reduced by hyperventilation and increases if breathing is slower. It is unclear whether the relation between blood flow to the brain and ventilation is affected during anaesthesia. This study will evaluate how blood flow to the brain is affected by anaesthesia and standard treatment of a possible reduction in blood pressure. Further, the study will assess whether blood flow to the brain is affected by development of a mesenteric traction syndrome. Lastly, the project will evaluate blood flow to the brain during short-term changes in the patient's ventilation by adjustments on the ventilator. Thirty patients planned for major abdominal surgery will be included in the project. The study will take place from the patient's arrival at the operation room and until two hours after the start of surgery. Placement of catheters and anaesthesia are according to standard care. Blood flow to the brain will be evaluated using ultrasound. Oxygenation of the brain, skin and muscle will be evaluated by probes that emit light. Depth of anaesthesia is assessed by recording the electrical activity of the brain. Blood pressure is measured by a catheter placed in an artery at the wrist and blood samples will be drawn from the catheter.

We performed a retrospective data analysis of patients with synchronously metastasized colorectal cancer, comparing the histological response on the primary tumour to chemotherapy combined with either vascular endothelial growth factor (VEGF) or epidermal growth factor receptor (EGFR) inhibition.

This study tests biopsy and tissue from patients who have been treated for primary rectal cancer at the Royal Marsden Hospital between 2011 and 2013, who have an mrTRG score at post-chemoradiotherapy MRI. It is a retrospective pilot study to determine the apoptotic and proliferative index count pre and post chemoradiotherapy.
