Filter by:The main purpse of this study is to evaluate the safety of KSD-101 in patients with EBV-associated Nasopharyngeal Carcinoma,to evaluate the initial clinical outcomes and evaluate the immune response to KSD-101 for the treatment in Patients with EBV-associated Nasopharyngeal Carcinoma.
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.
This is a prospective, single-center, single-arm, phase II clinical study. The study was intended to include patients with locoregionally advanced nasopharyngeal cancer identified by histology or cytology, who signed informed consent and met the screening criteria to enter the study. Patients will receive induction therapy (sintilimab + bevacizumab + gemcitabine, Q3W, 3 cycles) followed by IMRT+ Sintilimab. Consolidation therapy with sintilimab continued after radiotherapy until disease progression, intolerable toxicity, death, or the subject's decision to withdraw from the study, with a total treatment period of no more than 12 cycles.
The aim of this randomized controlled study is to investigate whether the previously developed artificial intelligence model can triage post-radiotherapy magnetic resonance images of patients with nasopharyngeal carcinoma and assist radiologists in their interpretation.
This trial aims to study the role of Adebrelimab combined with induction chemotherapy plus concurrent chemoradiotherapy (IC+CCRT) for high-risk locoregionally advanced nasopharyngeal carcinoma(LANPC).
To investigate the incidence, predictive markers, and survival impact of massive nasal bleeding in nasopharyngeal carcinoma (NPC) patients who received curative radiotherapy (RT) with/without chemotherapy. A total of 1327 patients with previously untreated, biopsy-proven NPC, and no distant metastasis were retrospective reviewed. Investigators analyzed the occurrence rates of massive nasal bleeding between different characteristics and tried to identify important predictive factors. Investigators compared overall survival between patients with and without massive nasal bleeding by Kaplan-Meier method.
This study aimed to investigate the value of a novel strategy of intermittent systematic chemotherapy (ISC) in widely metastatic nasopharyngeal carcinoma (wmNPC) patients who achieve objective response after systematic chemotherapy (SC).
Baseline information (demographics, medical history, etc.), nutritional status at admission and after treatment, depression, dysphagia, and quality of life (QOL) after treatment as well as adverse events are compared. Palliation to delayed dysphagia after radiotherapy for nasopharyngeal carcinoma (NPC) continues to be a challenge. Although nasogastric tube feeding (NGT) has been adopted widely, the weaknesses have yet to be improved by another enteral nutrition support mode. This study aims to observe the clinical efficacy of intermittent oro-esophageal tube feeding (IOE) in the treatment of delayed dysphagia after radiotherapy for (NPC). This is a prospective multicenter study with patients with delayed dysphagia after radiotherapy for NPC. Patients enrolled are randomly divided equally into the observation group and the control group. All patients receive conventional care, and the observation group received IOE while the control group received NGT for enteral nutrition support.
This is a prospective, single-arm, phase II clinical trial. The purpose of this study is to evaluate the efficacy and adverse effect of SBRT and LDRT combined with programmed death 1 (PD-1) antibody and chemotherapy in recurrent/metastatic nasopharyngeal carcinoma patients.
The investigators aim to explore a new EBV DNA surveillance method with both high sensitivity and specificity in nasopharyngeal carcinoma (NPC) patients. the investigators aim to conduct plasma EBV DNA counting by next generation sequencing (NGS) in non-metastatic NPC patients on their diagnose, after two cycles of induction chemotherapy (IC), and 4-8 weeks after definitive radiotherapy. The investigators aim to explore whether sequencing-based counting is better than PCR analysis in plasma EBV-DNA surveillance, so as to monitoring tumor responses to treatment and for guiding individualized treatment adaptation in the future.
