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.

Through a prospective, single-center, single-arm, phase Ib/II study, we aim to explore the safety and feasibility of a new treatment mode for upper esophageal cancer, which is that pembrolizumab combined with chemoradiotherapy as neoadjuvant therapy and then followed by radical surgery.
18F-Fluoroestradiol (18F-FES) is an estrogen receptor-targeting positron emission tomography tracer with high sensitivity and specificity for the detection of estrogen receptor（ER）-positive tumors . 18F-FES has been used as a predictive biomarker to demonstrate estrogen receptor heterogeneity , to evaluate the pharmacokinetics of estrogen receptor-targeted drugs ， to measure residual estrogen receptors during endocrine therapy and to determine biologically optimal doses of novel estrogen receptor-targeted drugs .This study aimes to explore the efficacy of 18F-FES PET/CT in evaluating the expression levels of ER in primary and metastatic breast cancer patients.
This study is a randomized, open labelled, placebo-controlled clinical trial. The main purpose is to verify the superior effect of gut microbiota directed diet intervention over standard diet intervention by evaluating the changes of HbA1c relative to baseline at 16 weeks and 28 weeks of follow-up.
The purpose of this study is to evaluate relationships between multiparametric imaging biomarkers and genetic analysis in glioblastoma patients.
Patients were randomly divided into experimental group and control group. The control group received routine postoperative treatment, while the experimental group took donepezil 5mg orally before going to bed every night from the first day after surgery. The catheter was removed and residual urine was measured in both groups 14 days after surgery, the catheter was successfully removed when the residual urine was less than 100ml. After 14 days, the patient was returned to the hospital for residual urine test, and the residual urine was repeated until the residual urine volume was less than or equal to 100ml. The incidence of postoperative urinary retention and adverse drug reactions were compared between the two groups.
In this study, we compared first-line VIC regimen with chemotherapy plus bevacizumab in Chinese patients with initially unresectable BRAF V600E-mutated mCRC. The principal goal was to evaluate the safety of VIC regimen, and to investigate the tumor response, the radical resectability, and the patient survival.
Tumor staging system based on clinicopathological charactertics has been used to guide treatment decisions. However, therapeutic outcomes of "early-stage" hepatocellular carcinoma (HCC) differs significantly, which strongly suggests the requirement for a re-staging of early HCC to inform treatment selection more precisely. Microvascular invasion (MVI) reflects malignant biological characteristics of early HCC, and has a potential role of guiding treatment selection. As such, the objective of this study is to investigate preoperative MVI prediction based on MVI-related genomic signatures of cell-free circulating tumor DNA (ctDNA) to establish a re-staging of early HCC. The investigators have detected 37 mutant genes associated with MVI in HCC tumor tissues. In this study, the investigators will design a gene panel based on these mutant genes to perform targeted gene sequencing on preoperatively collected ctDNA to identify genomic signatures associated with MVI. A nomogram to predict MVI before treatment will be generated by incorporating these genomic signatures. Based on a calculated optimal cut-off value of the nomogram, early HCC patients can be re-staged into subpopulations based on the nomogram-predicted risks of MVI. This study will develop a re-staging system of early HCC based on tumor biological charactertics, which is expected to accurately and individually guide treatment decisions and improve long-term survival outcomes.
Endometriosis occurs in about 10-15% of women of childbearing age and is a major cause of infertility and dysmenorrhea. Deep endometriosis is the most serious manifestation of endometriosis, which often affects the quality of life of patients and requires surgical treatment. Detailed description of DE lesions before operation can contribute to treatment planning. However, the detection rate of DE by conventional ultrasound is low, highly dependent on the experience of the examiner and poor reproducibility. Hysterosalpingo-contrast sonography can be used to assess the patency of the fallopian tube but cannot visualize other pelvic structures. Saline-infusion sonoPODography can provide a good acoustic window for pelvic tissue visualization. Therefore, this study is the first to present double contrast-enhanced ultrasound (Hysterosalpingo-contrast sonography and sonoPODography) examination of the pelvic cavity, based on the #Enzian classification system, for preoperative evaluation of DE lesions. The results of laparoscopic surgery were taken as the gold standard to compare the diagnostic efficacy of double contrast-enhanced ultrasound and conventional transvaginal ultrasound in preoperative evaluation of pelvic DE lesions, improving the preoperative diagnosis, reduce the risk of surgery and reduce postoperative recurrence. To compare the diagnostic efficacy of different examination methods in different compartment of DE, and to explore the best examination method suitable for different parts of DE, providing theoretical basis for further early screening and personalized treatment of DE in the future.
Secondary hyperparathyroidism (SHPT) is a common serious complication in the maintenance process of hemodialysis patients, characterized by diffuse or nodular hyperplasia of parathyroid glands. Parathyroidectomy for patients with drug-refractory SHPT is recommended in the clinical practice guidelines of the Global Organization for Improving Prognosis in Kidney Disease (KDIGO) and the Japanese Dialysis Therapy Society (JSDT) . Therefore, accurate localization and detection of parathyroid abnormalities is the key to avoid persistent recurrence of the disease. However, the sensitivity and specificity of the existing ultrasound and 99MTC-MIBI diagnosis are limited. CT examination is radiative and requires iodine contrast medium with nephrotoxicity, which may require timely dialysis and long-term monitoring for hemodialysis patients. 3T MRI has no radiation and does not need to use iodine contrast agent, which can well detect parathyroid lesions . Previous studies have reported that 3T MRI can diagnose primary hyperparathyroidism (PHPT), but the diagnostic efficacy of SHPT is still unclear. Therefore, this study aims to evaluate the preoperative diagnostic value of non-enhanced 3T MRI compared with 4DCT in patients with secondary hyperparathyroidism after hemodialysis.
