Shortened Course of Radiation Therapy After Trans-oral Robotic Surgery in Patients With HPV-Mediated Oropharyngeal Squamous Cell Carcinoma.
The goal of this study is to evaluate if a shorter course of therapy can improve the quality of life in patients receiving radiation therapy after trans-oral robotic surgery.
Combined Intraperitoneal Chemotherapy Regimen After Optimal Interval Surgery in Advanced Ovarian Cancer: BICOV-1 (Bidirectional Chemotherapy in Ovarian Cancer)
A multicenter, low-intervention, drug-based study to evaluate the feasibility and safety of a combined regimen of two intraperitoneal chemotherapy modalities (used in routine clinical practice) following interval surgery for the treatment of advanced ovarian cancer. This is an independent research project (free of commercial interests).
Effect of Losartan on the Neurohumoral Axis and Ventricular Remodeling of Patients With Severe Aortic Regurgitation Undergoing Valve Surgery.
Why Is This Study Important? The heart has valves that help control blood flow. Aortic regurgitation (AR) is a condition where one of these valves (the aortic valve) doesn't close properly, causing blood to leak back into the heart. Over time, this makes the heart work harder and grow larger …
Electroacupuncture Combined With Immune Checkpoint Inhibitors as Adjuvant Therapy After Surgery for Early-stage Non-small Cell Lung Cancer
Postoperative immunoadjuvant therapy has been proven to significantly reduce the risk of recurrence after resectable NSCLC, and has become a new standard of postoperative adjuvant therapy for stage II-III NSCLC. Immunotherapy faces challenges such as immune resistance, heterogeneity of biomarker expression, and limitation of immune-suitable population. How to reduce the …
Feasibility and Safety of a Single Working Element for Bipolar and Laser Enucleation in Prostate Surgery: A Prospective Study
A prospective feasibility study would be a practical first step, focusing on real-time assessment and ensuring the new working element's integration is safe and effective before broader clinical trials.
Comparison of Transvaginal Paracervical and Transperitoneal Approaches in Lymphadenectomy During v-NOTES Surgery for Patients Diagnosed With Endometrial Cancer
The aim of this study is to compare two types of lymphadenectomy (transperitoneal vs. paracervical) during the lymphadenectomy phase of endometrial cancer staging surgery performed using V-NOTES, a new and advanced technique. This study seeks to optimize the V-NOTES technique for endometrial cancer staging. This randomized, prospective, controlled study will …
A Study to Evaluate the Accuracy of aTCI Model of Cipepofol in Patients With General Anesthesia During Elective Surgery
This study is a multi-center (each center independently conducts the study according to the same research protocol), randomized, and open-label clinical study. The main objective is to verify and optimize the accuracy of the target-controlled infusion model of cipepofol.
Manipulation of the Gut Microbiome by a Standardized Preoperative Diet to Prevent Colorectal Cancer Recurrence and Metastasis Following Surgery
A single arm, prospective, single center Phase1/2 Dietary intervention trial for subjects diagnosed with colorectal cancer and scheduled for tumor resection more than 21 days from informed consent. Subjects will be provided 21 days of standardized High-fiber/low-fat meals and complete a food diary up until lunch on the day prior …
Immunotherapy (Toripalimab) for Reducing Recurrence Risk After Surgery for Mismatch Repair Deficient Stage IIB, IIC, or III Colon Cancer
This phase II trial tests how well immunotherapy (toripalimab) works for reducing the risk of cancer recurrence after surgery in patients with mismatch repair deficient stage IIB, IIC, or III colon cancer.
Is the CRP-Albumin-Lymphocyte (CALLY) Index Effective in Predicting Postoperative Delirium in Geriatric Patients Undergoing Hip Fracture Surgery
Introduction: Postoperative delirium (POD) is a common complication in elderly surgical patients and is significantly associated with prolonged hospital stays, cognitive impairment, functional decline, and increased mortality rates within 6 to 12 months. Its incidence has been reported to range between 10% and 70%, depending on the diagnostic criteria used, …
