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.
This study is a Phase II, single-arm, open-label, non-randomized, dose-escalation clinical trial to evaluate the efficacy and safety of ssCART-19 Cell Injection in the treatment of patients with CD19 positive Relapsed or Refractory acute lymphoblastic leukemia, including central nervous system infiltration.
The prognosis of recurrent and metastatic triple negative breast cancer (TNBC) is poor, and chemotherapy is still the main treatment for TNBC. Some studies have shown that combination therapy of antibodies targeting cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed cell death-1 (PD-1) significantly improves clinical benefit over PD-1 antibody alone. However, broad application of this combination has been limited by toxicities. Cadonilimab is a humanized immunoglobulin G1 bispecific antibody targeting PD-1 and CTLA-4. It mutates to eliminate Fc receptor and complement-mediated cytotoxic effects. The purpose of this study is to evaluate the efficacy and safety of Cadonilimab combined with chemotherapy as a first or second-line treatment of recurrent and metastatic TNBC. This study is a multicenter, single arm, phase II, non randomized, open label, Simon two-stage design. It is planned to enroll 27 late stage TNBC patients.
Nasopharyngeal carcinoma is one of the most common malignant tumors in China, with the progress of radiochemical comprehensive treatment, early stage The 5-year survival rate of nasopharyngeal cancer is more than 95%. However, due to the hidden site of nasopharyngeal carcinoma and the lack of obvious early clinical symptoms, more than 70% of the 87,000 newly diagnosed cases each year belong to the advanced stage of nasopharyngeal carcinoma, and the 5-year survival rate of advanced nasopharyngeal carcinoma is only about 70%. Therefore, early screening and diagnosis and early treatment are the key to improve the survival of patients with nasopharyngeal cancer. Selecting a sensitive and accurate biomarker for nasopharyngeal cancer and relying on a simple and feasible examination method for sampling detection will greatly improve the early diagnosis rate of nasopharyngeal cancer. DNA methylation is a form of chemical modification of DNA that can be done without altering the DNA sequence changes in genetic expression. The main role of DNA methylation is to regulate gene expression. Tumor suppressor genes play the functions of regulating cell differentiation, maturation and programmed death. However, if methylation of promoter region occurs, the expression of tumor suppressor genes is inhibited and the function is lost, resulting in cells remaining in the stage of low differentiation and proliferation, inhibition of apoptosis, formation of blood vessels by cluster cells, loss of cell adhesion, and formation of tumors. It can be seen that DNA methylation occurs in the early stage of tumor, and this biological feature makes it a strong application prospect in early tumor screening. There are many methods to detect DNA Methylation, among which methylation-specific PCR (MSP) can easily and quickly determine the methylation status of a specific gene, meeting the affordable, convenient, and easy to generalize characteristics required for screening tests. In combination with previous MSP experiments and previous reports, we found that the methylation levels of promoter fragments of H4C6, Septin9 and RASSF1A genes in nasopharyngeal carcinoma tissues were significantly higher than those in healthy human nasopharyngeal tissues. This suggests that methylation of these three genes may be used as biomarkers for early screening and diagnosis of nasopharyngeal carcinoma. Therefore, this study intends to detect the methylation status of H4C6, Septin9 and RASSF1A genes based on MSP method with simple operation and low cost. Using clinicopathological diagnosis as the gold standard, the value of this gene methylation index in early screening and early diagnosis of nasopharyngeal cancer was verified, providing a new detection index and method for improving the early diagnosis rate of nasopharyngeal cancer.
A retrospective analysis was conducted on patients with radioiodine-refractory thyroid carcinoma (RRTC) who underwent radioactive 125I seed implantation combined with anlotinib from January 2019 to October 2024 at Jiangxi Cancer Hospital. Data on tumor size changes before and after treatment, serological tests (including serum TG, TgAb, CTn, CEA, etc.), changes in patients' pain scores, and side effects were collected to evaluate the clinical efficacy and safety of this therapy.
The study is designed to confirm the performance of the 3D Medicines Corporation OCS test in diagnosis of epithelial ovarian cancer in patients with adnexal mass. To this end, blood samples from female patients with adnexal mass required surgical resection from four centers are obtained and analysis in the study.
Introduction: The incidence of occult cervical lymph node metastases (OCLNM) is reported to be 20%-30% in early-stage oral cancer and oropharyngeal cancer. There is a lack of an accurate diagnostic method to predict occult lymph node metastasis and to help surgeons make precise treatment decisions. Aim: To construct and evaluate a preoperative diagnostic method to predict occult lymph node metastasis (OCLNM) in early-stage oral and oropharyngeal squamous cell carcinoma (OC and OP SCC) based on deep learning features (DLFs) and radiomics features. Methods: A total of 319 patients diagnosed with early-stage OC or OP SCC were retrospectively enrolled and divided into training, test and external validation sets. Traditional radiomics features and DLFs were extracted from their MRI images. The least absolute shrinkage and selection operator (LASSO) analysis was employed to identify the most valuable features. Prediction models for OCLNM were developed using radiomics features and DLFs. The effectiveness of the models and their clinical applicability were evaluated using the area under the curve (AUC), decision curve analysis (DCA) and survival analysis.
Multiple myeloma (MM) is a disease caused by malignant plasma cell proliferation disorder. Survival outcomes continue to vary widely even within uniformly treated clinical trial populations. How to construct a clinical prognosis model of MM through real-world data to guide the selection of treatment options, standardize patient management, and improve survival expectations, is a major problem that needs to be solved urgently. It is necessary to build an MM-specific cohort in China to comprehensively understand the characteristics of MM patients, explore treatment options, and improve prognostic factors for survival outcomes.
Objective: To assess the clinical efficacy of different compression methods within 48 hours after endovenous radiofrequency ablation (RFA) in terms of great saphenous vein closure rate, postoperative complications, quality of life, time to return to normal work, and patient satisfaction.
Esophageal cancer imposes a significant burden in China, accounting for over 60% of the global disease burden. While surgery remains a common and highly effective treatment for esophageal cancer, patients often experience multiple physical and psychological symptoms postoperatively, severely affecting their recovery outcomes and quality of life. Although existing exercise or psychological intervention programs have shown some effectiveness, issues such as relatively singular intervention content, imprecise intervention timing, and vague intervention details persist. This project, based on previous research foundations (including the development of symptom measurement tools and the identification of key recovery periods), is guided by symptom management theory and knowledge translation models. Taking a perspective of the synergistic impact of physical and psychological symptoms, the study focuses on patients undergoing esophageal cancer surgery. Initially, evidence-based literature review, focus group interviews, and expert consultations were conducted to develop a combined exercise and psychological intervention program, integrating subjective (CSCA_EC) and objective (6MWT) measurement indicators, named "Recovery For EC." Subsequently, the program was preliminarily applied in clinical settings using a mixed-methods approach, combining quantitative quasi-experimental design (108 cases) and qualitative interviews to assess its acceptability. The final clinical trial version of the Recovery For EC program was developed to provide patients with a tool for self-monitoring recovery outcomes and offer clinical healthcare professionals guidance for implementing precise and personalized rehabilitation management.
