View clinical trials related to Nasopharyngeal Carcinoma.
Filter by: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.
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 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. 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.
Radiation therapy has become the preferred treatment for nasopharyngeal cancer due to the sensitivity of nasopharyngeal carcinoma to radiation. However, even with the use of intensity-modulated radiation therapy (IMRT), radiation-induced temporal lobe injury (RTLI) can be a severe complication. Patients with RTLI may experience long-term memory loss, personality changes, physical dysfunctions, and other symptoms, which seriously impair their quality of life and long-term prognosis. Currently, the diagnosis of RTLI primarily relies on clinical symptoms and imaging examinations such as computed tomography (CT) and conventional MRI. However, these methods only enable the diagnosis of RTLI at a late stage when it is irreversible and cannot be effectively treated. Therefore, the early identification or individualized prediction of RTLI after IMRT holds exceptional importance for improving the quality of life in nasopharyngeal carcinoma patients. The exact mechanism of RTLI remains unclear. Many clinical covariates have been proven to be associated with RTLI in NPC patients, including stage, age, and dosimetric parameters. In addition, it was reported that each patient's temporal lobe exhibits unique genetic susceptibility to radiation exposure. In this study, we aim to predict the occurrence of RTLI by analyzing clinical factors and heterogeneity of temporal lobe tissue prior to irradiation. Finally, we want to construct and validate a prediction model for RLTI, which can support clinician decision-making in developing individualized treatment plans and providing preventive measures.
The study is to evaluate the antiemetic effect of adding fosaprepitant to biplet regimen of tropisetron and dexamethasone for patients with cervical cancer or nasopharyngeal cancer treated with radiotherapy and concomitant weekly cisplatin chemotherapy in a south Chinese cohort.
This is a prospective phase II clinical randomized controlled study, the purpose of this study is to assess whether superficial parotid lobe-sparing intensity-modulated radiotherapy (SPLS-IMRT) can decrease the incidence of xerostomia versus conventional IMRT (C-IMRT) in NPC patients.
This study aims to investigate the use of 18F-FMISO PET in identifying hypoxic subvolume for dose escalation radiotherapy in nasopharyngeal cancer and thus improve local control without significant increase in toxicities.
A phase I/II clinical study of JS004 in subjects with head and neck cancer in China, to evaluate the safety, tolerability, PK, immunogenicity, antitumor activity and biomarkers of JS004, define the RP2D. A cycle is 21 days (3 weeks) which includes JS004 being administered IV Q3W and JS004 combine with JS001 being administered IV Q3W. All patients will be treated until disease progression per RECIST v1.1 and iRECIST, or intolerable toxicity per CTCAE 5.0, withdrawal of consent, or end of the study, whichever occurs first.Disease progression must be confirmed at least 4 weeks but no longer than 8 weeks after initial documentation of progression.
This phase I trial studies the side effects of image-guided hyper-fractioned proton therapy in treating patients with head and neck cancer that has spread to nearby tissue or lymph nodes (locally advanced) and cannot be removed by surgery (unresectable). Radiation therapy uses high energy protons to kill tumor cells and shrink tumors. The change in dose radiation frequency and dose investigated in this study may help to better control the tumor and prevent it from coming back or growing. The goal of this study is to test a new radiation schedule that administers more radiation to the tumor tissue using image guided proton therapy for patients that have a high risk of having a tumor recurrence (the tumor comes back after treatment).
To evaluate the efficacy of induction chemotherapy with nedaplatin, docetaxel and 5-Fluorouracil followed by concurrent nedaplatin combined with radical radiotherapy in locally advanced nasopharyngeal carcinoma.
