Filter by:The primary objective of radiation therapy is to deliver a therapeutic dose of radiation precisely to the target while minimizing exposure to healthy surrounding tissues. Image-guided radiation therapy (IGRT) involves acquiring cone beam computed tomography (CBCT) scans just before or during treatment sessions. By comparing the CBCT images with the reference images from the treatment planning process, clinicians can make necessary adjustments to ensure precise targeting and account for any changes that may have occurred since the initial planning. Conventional CBCT technology is, however, limited by several factors including long acquisition times that result in motion artifacts in the image, smaller fields of view that limit the volume of anatomy that can be imaged, poor image quality that limits soft tissue visibility, and artifacts created by dense metal implants. This study will evaluate a novel CBCT imaging solution ("HyperSight") that has the potential to address the challenges of conventional CBCT.
The goal of this prospective, single centre, 1:1, Post Market, randomized controlled, Investigator Initiated trial, is to compare the feasibility, safety efficacy, and clinical outcomes of colonic endoscopic submucosal dissection (ESD) utilizing a novel rigidizing overtube called Pathfinder® Endoscope Overtube (Neptune Medical, Burlingame California, USA) device in comparison to conventional ESD. The research team hypothesize that with utilizing a novel rigidizing overtube the procedure time including dissection speed and closure time will be faster due to higher scope stability and greater control over the scope tip. Subsequently, the investigators anticipate lower immediate or delayed adverse events.
Gastrointestinal tumors (esophageal cancer, gastric cancer, colorectal cancer) seriously threaten human health, with a high incidence rate and cancer related hope mortality. Digestive endoscopy is the main method for screening gastrointestinal tumors. Early screening of gastrointestinal tumors can improve the detection of early cancer and improve prognosis. The five-year survival rate of early stage tumors after comprehensive treatment can reach 90%, while the five-year survival rate of late stage tumors is less than 30%. Therefore, the screening of gastrointestinal tumors is very important. Studies have shown that there are similarities in risk factors for gastrointestinal tumors, such as age, gender, family history, smoking, alcohol consumption, etc. Currently, established digestive malignancies are targeted at a single malignant tumor. At present, there is a lack of understanding of the overall risk factors associated with gastrointestinal tumors and the establishment of relevant risk prediction models. Therefore, we conducted a prospective, multicenter cross-sectional study to explore the independent risk factors of combined gastrointestinal tumors and establish a risk prediction model for combined screening of gastrointestinal tumors.
This is a Phase I study to evaluate the safety and tolerability of sacituzumab govitecan in combination with capecitabine for advanced gastrointestinal cancers after progression on standard therapy, and to assess correlation of outcomes with the biomarker Trop-2.
This is a single-arm, multicentre real-world observational study of TAS-102 in combination with regorafenib or fruquintinib for third-line and above advanced colorectal cancer.
The incidence of postoperative hypothermia in patients with laparoscopic gastrointestinal tumors is high. Hypothermia increases the risk of postoperative complications and medical costs. Early warning can effectively reduce the incidence of postoperative hypothermia in patients. Multivariate prediction models help identify high-risk patients and reversible factors. At present, there are few reports on the risk factors and prediction models of postoperative hypothermia in patients with laparoscopic gastrointestinal tumors. Therefore, this study aims to clarify the risk factors of postoperative hypothermia in patients with laparoscopic gastrointestinal tumors. Four machine learning algorithms, traditional Logistic regression analysis, decision tree, random forest and naive Bayes, were used to establish risk prediction models. According to the TRIPOD statement, C-index, Hosmer-Lemeshow ( H-L ) test and decision curve analysis ( DCA ) were used to evaluate the prediction and fitting effects of the models in all aspects, and the optimal model was selected and verified. Provide reference for subsequent research.
The incidence of oxaliplatin allergy reactions is between 12-15%, while the incidence of severe (grade 3-4) allergic reactions is between 0.5-2%. The purpose of this study is to prospectively investigate the incidence of oxaliplatin allergy and neurotoxicity, and to evaluate the use of effective anti-allergic and desensitization therapies to enable patients who are already allergic to oxaliplatin to complete their prescribed doses smoothly.
The purpose of this study is to develop, refine, and pilot test a text-messaging micro-intervention focused on improving communication skills for couples in which one partner has gastrointestinal cancer. For the pilot testing portion of the study, couples will be randomized (1:1) to receive the text-messaging communication micro-intervention or to a waitlist control group. All couples will be asked to complete questionnaires before randomization and 30 days post-randomization. Couples in the waitlist control group will be offered the text-messaging micro-intervention after completing the second set of surveys (30-days post-randomization).
Cachexia is a common complication of various advanced malignant tumors, which seriously affects the quality of life and survival time of patients. In view of the clinical problem of non-nutritional response in patients with cachexia, the investigators plan to carry out a clinical case-control study on the intervention of creatine combined with curcumin in participants with cachexia. On the whole, the investigators limited the study subjects to upper digestive tract tumors and diagnosed participants with early cachexia. The main purpose of this study is to determine whether the combination of the two can play a positive and stable role in inhibiting the inflammation of cachexia and improving metabolic status, so that basic nutrition can play a role, in order to reduce the level of skeletal muscle consumption, maintain weight, improve quality of life, save medical costs and extend survival time.
Comparison of tumor volume, number, and SUVmax of different primary foci (gastric, duodenal, and colon cancer), lymph node metastases (neck and supraclavicular, mediastinal, abdominal, and pelvic), and distant metastases (brain, lung, liver, bone, pleura, and peritoneum) detected by 18F-FAPI versus 18F-FDG PET/CT imaging.
