Active clinical trials for "Nasopharyngeal Carcinoma"

Currently, nasopharyngeal carcinoma (NPC) patients who had level II involvement with extracapsular extension (ECE), and/or had a maximum nodal axial diameter (MAD) of greater than 2cm in level II will be recommended to receive level Ib-covering IMRT according to the International Guidelines. Our previous study, which retrospectively analyzed a cohort of 390 patients, indicated that it should be safe and feasible for patients who only had at least one of the above two radiological features. Thus, the investigators conduct this non-inferior phase 3, randomized trial to further determine the feasibility of sparing level Ib in patients who had level II involvement with ECE, and/or had a MAD of greater than 2cm in level II.

Head and neck squamous cell carcinoma (include nasopharyngeal carcinoma) is one of the most common malignant tumor in China, and radiotherapy is the main treatment method. Radiation-induced dermatitis is one of the most common complications of head and neck squamous cell carcinoma patients during radiotherapy. Severe radiation dermatitis will cause secondary infection, severe pain, and even lead to the interruption of radiotherapy. On the one hand, it will affect the efficacy of tumor treatment, which may affect the long-term survival of patients, and on the other hand, it will also seriously affect the quality of life of patients. Tetrahydrobiopterin（BH4）, also known as sapropterin, has been shown not only to reduce the severity of acute radiation dermatitis but also to enhance the repair of skin injury in animal experiments. It may be a new approach and method for the prevention and treatment of radiation-induced dermatitis

Toxic and side effects during and after chemoradiotherapy for nasopharyngeal carcinoma seriously affect patients' treatment compliance and long-term quality of life. Active and effective prediction, prevention and management of toxic and side effects is an important element to improve the prognosis of patients. Leucogen has the ability to promote the growth and maturation of granulocytes in the bone marrow and the proliferation of leukocytes, and is widely used in radiation therapy and chemotherapy-induced leukopenia in malignant carcinomas. In addition, leucogen may have potential anticancer synergistic effects. Therefore, based on the application prospect of leucogen in preventing myelosuppression during chemotherapy for solid tumors, the study was designed to investigate the efficacy and safety of leucogen versus placebo on leukocyte and platelet whole-course management assisted by platinum plus low-dose long-term continuous intravenous infused 5-fluorouracil chemotherapy in the treatment of stage IV, recurrent or metastatic nasopharyngeal carcinoma.

This project focuses on the early prediction and diagnosis of radiation-induced brain injury in nasopharyngeal carcinoma patients. Based on the big data of imaging and serum metabonomics samples, combined with the machine learning analysis method， dynamic evolution mode of radio-metabolomics characteristics was analyzed . The potential internal relationship between brain structure and serum metabolic changes was explored, and the individualized prediction model was constructed to screen out the high-risk patients with brain injury after tumor radiotherapy, so as to provide reference for the diagnosis of radiation-induced brain injury caused by tumor. radiotherapy Intelligent diagnosis provides a new theoretical and practical basis.

Epstein-barr virus (EBV) infection is a necessary factor of nasopharyngeal carcinoma (NPC). The incidence of NPC in endemic regions reaches 24.60/100,000 people, far higher than that of the worldwide average. However, no EBV prophylactic vaccines is clinically available so far, which is largely hampered by the difficulties in selecting optimal vaccine design target out of 13 glycoproteins on the surface of EBV. In this study, we utilized humanized gp42-IgG antibodies to explore the dominant epitopes of gp42, one of the functional EBV glycoproteins during virus entry, to facilitate prophylactic vaccine design.

The diagnosis of cervical lymph node in nasopharyngeal carcinoma is difficult. Magnetic resonance imaging based deep learning model may be a noninvasive and rapid diagnostic method for cervical lymph node. Thus, the investigators aimed to develop and externally validate a deep learning model to assist in the diagnosis and localization of metastatic lymph nodes in nasopharyngeal carcinoma.

All participants will be tested for EBV associated biomarkers, including EBNA1-IgA, VCA-IgA, BNLF2b total antibodies (P85-Ab) et al. For all male participants and P85-Ab positive female participants, EBV DNA in plasma will be tested. Screening positive participants will be followed up annually. All subjects will also be followed by record linkage to Cancer Register and Population Register.

Develop a deep learning algorithm via nasal endoscopic images from eight NPC treatment centerto detect and screen nasopharyngeal carcinoma(NPC).

This study is a genetic analysis of aberrations in circulating tumor DNA (ctDNA) in patients in Asian countries. This study protocol is divided into parts describing several subanalyses that differ in terms of cancer types, analytical methods, participating countries, and participating institutions.

The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.
