Filter by:The latest research has found that the use of positron-labeled FAP inhibitors for targeting FAP has achieved very good results in displaying tumor stroma, especially for tumors with poor FDG PET/CT observation, such as liver cancer, renal cancer, and gastric cancer. Although the studies were based on small sample data or case reports, they achieved significantly better results than 18F-FDG [13,15-17]. For patients who meet the inclusion and exclusion criteria, using FAPI PET/CT and FDG PET/CT imaging may have guiding significance for your treatment. If distant metastasis is found, information such as the location, size, and quantity of metastasis can be provided to provide objective imaging information for further treatment; We will promptly provide detailed information to you and your supervising physician, who will guide your personalized treatment. The drugs used have undergone strict quality inspection, and currently, no adverse reactions have been found in multiple medical institutions both domestically and internationally. If you experience any discomfort, new changes in your condition, or any unexpected circumstances during the study period, regardless of whether it is related to the study or not, you should promptly notify your doctor or contact our research leader. He/she will make a judgment and provide appropriate medical treatment. We will provide a certain proportion of compensation for any additional visits and expenses incurred during this examination. The entire research process is under the supervision of relevant departments of Guangdong Provincial People's Hospital. If you encounter any questions during the research process, you can consult the research doctor.
The goal of this clinical trial is to explore the feasibility of a new mode of chemotherapy and bevacizumab induction therapy combined with immunotherapy as first-line treatment for patients with initially unresectable metastatic colorectal cancer (MSS). The main questions it aims to answer are: 1. To explore the efficacy and safety of this treatment mode 2. Try to study treatment benefit the characteristics of the crowd Participants will combined with immunotherapy after chemotherapy and bevacizumab induction therapy.
The objective of this pilot study is to compare the effectiveness of mailed outreach of two stool based tests, Cologuard and the fecal immunochemical test (FIT) in screening eligible adults ages 45-49 receiving care at the University of California San Diego Health system.
Microscopic colitis (MC) is an inflammatory bowel disease characterized by chronic non-bloody watery diarrhoea and a macroscopically normal colonic mucosa upon endoscopic exploration (colonoscopy). The diagnosis is performed by microscopic examination of mucosal biopsies that reveal specific histopathological change. Between 4-20% of patients with chronic non-bloody diarrhoea who undergo colonoscopy with serial biopsies are diagnosed with MC. It has long been hypothesized that the microbiome plays a key role in the pathogenesis of MC. In patients with collagenous colitis, faecal stream diversion results in inflammation and histological remission, followed by disease relapse after intestinal transit is reconstructed. Moreover, studies carried out with faecal samples obtained after colonoscopy have demonstrated microbiome changes (reduced alpha diversity and higher microbial dysbiosis index) in patients with active MC. To avoid potential bias due to the effect of colonic lavage prior to colonoscopy in microbiota composition, the researchers of the present study previously evaluated the microbiome in faecal samples obtained before the diagnostic colonoscopy in patients with active MC. The results confirmed a reduced alpha diversity in diarrhoea groups; however, there were no differences between MC, bile-acid diarrhoea and functional diarrhoea. The microbial dysbiosis index was significantly higher in MC compared to the other diarrheal groups, but no bacterial species showed a significantly different relative abundance. On the other hand, the risk of colorectal cancer (CRC) or adenoma seems to be reduced in MC compared to controls. Growing evidence suggests microbial dysbiosis is a crucial environmental factor in the initiation of precancerous lesions of CRC such as adenomas. The objective of the current multicentric prospective study is to assess the differences in the mucosa adherent intestinal microbiome between patients with MC, non-MC chronic diarrhoea, healthy controls and patients with advanced colon adenomas. In addition to the study of the microbiome, sociodemographic variables, history of drug usage, diets and specific characteristics of diarrhoea will be collected. The hypothesis of the present study is that CM presents a specific mucosa adherent intestinal bacterial profile that may be relevant in the pathogenesis of the disease and that, additionally, may also play a protective role against the development of CRC and adenomas.
A Phase II Study to Assess the Efficacy and Safety of Cadonilimab Combined With Fruquintinib and SBRT as A third-line and Posterior Line Treatment in Patients With MSS Colorectal Cancer
The goal of this randomized controlled trial is to investigate whether ctDNA methylation is a more precise indicator to guide postoperative adjuvant chemotherapy in stage Ill colorectal cancer. The main questions it aims to answer are: 1. Whether ctDNA methylation-guided escalation strategy is superior to standard treatment for stage III high-risk CRC patients. 2. Whether ctDNA methylation-guided de-escalation strategy is non-inferior to standard treatment for stage III low-risk CRC patients. 325 cases were included in the high-risk cohort (T4 and/or N2) and 665 cases were included in the low-risk cohort (T1-T3, N1). Then patients in each cohort were randomly assigned to ctDNA-guided treatment (ctDNA-guided group) and standard treatment (standard treatment group) in a ratio of 2:1. The standard treatment group and ctDNA-negative group in the high-risk cohort were treated with XELOX regimen for 6 months, and the ctDNA-positive group in the high-risk cohort was treated with cmFOLFOXIRI regimen for 6 months. The standard treatment group and the ctDNA-positive group in the low-risk cohort were treated with XELOX regimen for 3 months, while the ctDNA-negative group in the low-risk cohort did not receive adjuvant chemotherapy.
The scope of this research is to examine the acceptability and feasibility of a refined web-based intervention ("STOMA Care" app) by conducting a randomized pilot consisting of bladder and colorectal cancer patients scheduled for ostomy surgery at Mount Sinai Health System and their primary caregivers. This study aims to explore the impact of the app on stoma-related knowledge and beliefs, patient stoma-care skills and self-efficacy beliefs, and self-regulation and adaptation (e.g., distress and quality of life) among patients and their informal caregivers.
This SafeHeal study is designed to assess the overall safety of the low anterior resection (LAR) standard of care cancer treatment by establishing a definition of major complications. The current literature on standard of care reports adverse events/complications but does not provide a single endpoint that can be used to compare the safety of LAR cancer treatment to alternative therapies or treatments. This study will allow for the establishment of a new single safety endpoint for LAR standard of care cancer treatment.
This study will help to determine the main clinical symptom differences between patients of different ages, discover the family genetic predisposition of patients of different ages, and obtain the differences in pathological characteristics of patients of different ages, so as to provide help and basis for more accurate and earlier prevention and treatment of colorectal cancer.
Currently, domestic and international research on dexmedetomidine as well as anxiety and depression is more focused on basic research. In terms of clinical research, dexmedetomidine is more often used in pediatrics, short surgeries, intensive care units, etc., for sedation and analgesia; while less research has been done for the relief of anxiety and depression. At present, on the one hand, the number of oncology patients is on the rise both at home and abroad, and on the other hand, anxiety and depression account for an increasing proportion of healthcare in the world. Tumor patients, as a high prevalence group of anxiety and depression, their prognosis and regression are also more complicated. Therefore, exploring the role of intranasal administration of dexmedetomidine in relieving perioperative anxiety and depression in oncology patients has a very strong practical basis and clinical significance.
