Active clinical trials for "Nasopharyngeal Neoplasms"

Nasopharyngeal carcinoma (NPC) is commonly observed in southern China, particularly in the Pearl River delta area and the Xijiang River basin in the Guangdong and Guangxi provinces, with an incidence rate as high as 25-50 per 100,000. The National Comprehensive Cancer Network guidelines (version 1, 2018), have recommended use of induction chemotherapy followed by CCRT as category 2A for NPC, especially the TPF regimen as category 1 for EBV-associated disease. The nanoparticle albumin-bound paclitaxel (Nab-paclitaxel) is a promising new agent with more efficient entry to the tumor microenvironment and preferential uptake by cancer cells. Superior activity of Nab-paclitaxel regimens without the necessity for antianaphylactic pretreatments has been shown in various solid tumors compared with the traditional solvent-based paclitaxel-based ones. However, the safety and efficacy of combination of Nab-paclitaxel, cisplatin and Fluorouracil (APF) has not been determined in patients with locoregionally advanced NPC. In this prospective, Multi-centeric, Open, Non-controlled phase II clinical trial, investigators perform an exploratory study to the efficacy and Safety of APF.

Aim of the work To determine if chronic rhinosinusitis with nasal polyps' (CRSwNP) populations are vitamin D deficient. To determine the possible anti-inflammatory effect of vitamin D supplementation (clinically & histologically). & investigate its relation to immunohistochemical tissue expression of basic fibroblast growth factor

The primary purpose of this study is to explore the significance of analgesic treatment for radiation-induced oral mucositis pain in patients with nasopharyngeal carcinoma during radiotherapy, and to compare the analgesic effect of morphine controlled-release tablets with that of fentanyl transdermal patch. Half of participants will receive morphine controlled-release tablets,while the other half will receive fentanyl transdermal patch.

The purpose of this study is to evaluate the safety of the designed LMP1-CAR -T cells and determine whether the CAR-T cells are effective in the treatment of EBV associated malignant tumors.

Background: - Nasopharyngeal carcinoma (NPC) a common malignant tumor in southern China and Southeast Asia. Infection with Epstein-Barr virus is believed to be necessary for the development of NPC; non-viral environmental factors, such as dietary consumption of nitrosamines, cigarette smoking, betel nut chewing, wood dust exposure and possibly exposure to formaldehyde, have been implicated in the disease. Genetic susceptibility may also play an important role in the development of NPC. However, more information is needed on the connections between genetic and environmental factors in NPC, particularly in areas where the cancer risk appears to be greatest. Objectives: - To examine the main effects of genetic factors and environmental exposures (e.g., cigarette smoking, betel nut chewing, formaldehyde, wood dust) on nasopharyngeal carcinoma risk. Eligibility: Cases: Individuals at least 21 years of age who have been diagnosed with NPC at one of the participating hospitals and have been residents of northern Taiwan for at least 6 months. Controls: Hospital patients with diseases other than NPC at least 21 years of age, matched to NPC patients based on hospital, age at diagnosis, gender, and ethnicity. Design: This study involves a risk factor interview, medical record abstraction and biological sample collection. Participants will respond to interview questions about their lifestyle and risk factors thought to be involved in NPC development. All participants will provide blood and saliva samples for study. Participants who have been diagnosed with NPC will also provide consent to allow researchers to study tissue samples taken during tumor biopsies or surgeries. Treatment will not be provided as part of this protocol.

This is single-center, prospective, non-randomized study

Malignant transformation of adenomas of the duodenum is now the leading cause of death in familial adenomatous polyposis (FAP) patients who had a restorative proctocolectomy. Ursodeoxycholic acid (UDCA) modifies the biliary acid profile and could reduce the severity of duodenal adenomas and prevent such transformation.

This study evaluates the hyperfractionated IMRT in the treatment of patients with locally recurrent nasopharyngeal carcinoma. Half of participants will receive hyperfractionated IMRT, while the other half will receive conventional fraction IMRT.

To test the therapeutic ratio of additional chemotheray on advanced nasopharyngeal carcinoma.

The purpose of this study is to assess if curcumin, a commonly used food spice, can regress colorectal adenomatous polyps in patients with familial adenomatous polyposis, an inherited form of colorectal cancer.
