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 …
Comparison of the Efficacy of Flexible Ureteroscope and Percutaneous Nephroscopic Surgery in the Treatment of 2-4cm Kidney Stones
Urolithiasis is a common disease in urology. With the continuous progress of science and technology, the treatment of kidney lithiasis has undergone revolutionary changes, and the previously commonly used open surgical lithotomy method has been gradually eliminated, and replaced with less traumatic treatment methods. Percutaneous nephroscopy can theoretically treat the …
Evaluation of the Contribution of a DEMaterialized VIdeo-pedagogical SUpport in the Care Pathway of Lung Cancer Surgery Patients
Uni-centric, randomized, open-label, prospective interventional-comparative study, with a control arm (patients receiving standard preoperative information) and an experimental arm (patients receiving standard preoperative information and having access to a dematerialized educational video support).
A Study on the Treatment of Early Small Breast Cancer With Ultrasound-guided Vacuum-assisted Excision Combined With Surgery
The aim of this clinical trial is to assess the feasibility and safety of ultrasound-guided vacuum-assisted excision (VAE) in the treatment of early breast cancer with Tis (carcinoma in situ) or T1 (maximum tumor diameter ≤2cm) and negative axillary lymph nodes on imaging. The main question it aims to answer …
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.
The Effect of Nocturnal Dexmedetomidine on Postoperative Sleep Quality and Fatigue After Major Surgery in Elderly Patients: DEXSLEEP Study
In the aftermath of major surgery, many patients suffer from pain, fatigue, reduced general well-being, and cognitive dysfunction. Another common concern after major surgery is sleep impairment and there is little known about its effect on postoperative morbidity, especially postoperative fatigue and muscle function. Dexmedetomidine has been shown to possibly …
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.
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 …
