There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
From 2021 to 2022, 31 patients with unifocal breast cancer were enrolled for precision breast conserving surgery (PBCS) guided by wire guided localization (WGL) combined with CT guided 3D reconstruction. Surrounded WGL was performed under local anesthesia, followed by an immediate contrast enhanced CT scan. PBCS guided by CT guided 3D reconstruction was performed one day after the localization. Women who underwent palpation guided breast conserving surgery (BCS) were included as control. Two-sided Student t test, Fisher's exact test and chi-square test was applied.
Accurate evaluation of tumor boundaries in breast-conserving surgery is critical to reducing the second operation of patients. Near-infrared (NIR) fluorescence imaging using molecular agents has shown promise for in situ imaging during resection. However, very effective probes can be applied to clinical trials up to now, which limits the clinical application of fluorescence imaging. Here we developed a new technology that can quickly identify the tumor area of the resected breast tissue during the operation and distinguish the tumor boundary. In brief, the breast tissues were incubated with the probe immediately after intraoperative resection and imaged to identify the tumor area and distinguish the tumor boundary. The accuracy of fluorescence imaging was confirmed by pathological diagnosis.
To evaluate the safety of therapeutic immunological agent against EBV-positive advanced malignancies, examining the incidence, type of occurrence, and severity of adverse events in relation to the agent tested, and initially exploring the effectiveness of the immunological agent.
This is a multi-center, open-label, non-controlled, single-arm clinical trial to evaluate the safety, efficacy and population pharmacokinetics of Amphotericin B cholesteryl Sulfate Complex for Injection domestic formulations (ABCD) in the treatment of confirmed invasive candidiasis (IC) and confirmed/clinically diagnosed invasive aspergillus (IA) disease.
The program aims to enroll patients with stage high risk (AJCC 8th, T3-4N2-3M0) . Patients will receive 3 cycles of induction chemotherapy with gemcitabine and cisplatin and concurrent cisplatin-radiation plus Sintilimab, and then receive 11 cycles of Sintilimab after intensity-modulated radiotherapy (IMRT). All patients will receive IMRT. Sintilimab will begin on day 1 of induction chemotherapy and continue every 3 weeks for 17 cycles.
Chordoma is a rare but locally invasive cancer that arises from the embryonic notochord. Total resection is challenging in mobile spine because of the complex anatomy and bone invasion.
This is a Phase I study designed to evaluate if LB4330, an anti-Claudin 18.2 and CD8 T cell activator fusion protein, is safe, tolerable and efficacious in participants with Advanced Solid Tumors
This study attempts to compare safety and long-term oncological outcomes between laparoscopic surgery and open surgery in the treatment of clinical T4b Colorectal cancer.
The goal of this multicenter observational study is to evaluate the lung cancer diagnostic value of epigenetic imprinting detection in bronchoalveolar lavage. This study will mainly focus on varifing the previously identified epigenetic imprinting biomarkers for lung cancer and upgrading and validating a lung cancer imprinting diagnostic model specifically for bronchoalveolar lavage. The lavage sample will be collected from each eligible paticipants under bronchialscopy and undergo QCIGISH detection to analyze the allelic expression status of imprinted genes. The QCIGISH detection results will be compared with the final surgical histopathology. No interventions will be taken according to the QCIGISH detection results.
After obtaining an institutional ethics approval (#2021833), the investigators retrospectively reviewed patients with Pelvic organ prolapse (POP) who underwent Transvaginal Mesh (TVM) in their hospital during June 2008 and December 2020. The goal of this observational study is to introduce the Vaginal Adventitia Reserved and Anatomical Implant Technique in Transvaginal mesh surgery, and to report long term efficacy and safety results of this technique. The main questions it aims to answer are: - How to reduce the potential risk of mesh-related complications when performing TVM? - How effective is the use of the Vaginal Adventitia Reserved and Anatomical Implant Technique when performing TVM? Participants will be asked to fill the Pelvic Floor Distress Inventory (PFDI-20) at final follow-up, and the Prosthesis/Graft Complication Classification Code was used to record the mesh-related complications.
