Filter by:The hypothesis of the study is to address the efficacy and toxicity profile of aforementioned four modalities for rT1-2 NPC. Characters of the patients: - list item one: 168 patients, median age 48 years (range 16-75 years） proven rT1-2 NPC were diagnosed - list item two: Treated with four different irradiation modalities(3D-CRT,IMRT, BT , BT Combined 3D-CRT or IMRT). - list item three: Median time to recurrence was 30 months (range 1-180months). The median follow-up time was 28 months (range, 4-135 months).
There is a need for better visualization of polyps during surveillance endoscopy in patients with hereditary colon cancer syndromes like Familial Adenomatous Polyposis (FAP) and Lynch Syndrome (LS), to improve the adenoma detection rate. Optical molecular imaging of adenoma associated biomarkers is a promising technique to accommodate this need. The biomarker Vascular Endothelial Growth Factor (VEGF) is overexpressed in adenomatous colon tissue versus normal tissue and has proven to be a valid target for molecular imaging. The University Medical Center Groningen (UMCG) developed a fluorescent tracer by labeling the VEGF-targeting humanized monoclonal antibody bevacizumab, currently used in anti-cancer therapy, with the fluorescent dye IRDye800CW. The investigators hypothesize that when bevacizumab-IRDye800CW is administered to patients, it accumulates in VEGF expressing adenomas, enabling adenoma visualization using a newly developed near-infrared (NIR) fluorescence endoscopy platform (NL43407.042.13). This hypothesis will be tested in this feasibility study, next to the determination of the optimal tracer dose.
Two Phase Ⅲ trials (TAX323 and TAX324) showed induction chemotherapy adding docetaxel to cisplatin plus fluorouracil (TPF) could significant improve survival in head and neck cancer, and a Phase Ⅱ trial from Hong Kong by Hui and colleges with this strategy has also been reported in nasopharyngeal carcinoma (NPC). However, whether three cycles induction could delay the whole time of treatment and reduce the survival benefit are still unknown. A retrospective study of one cycle TPF induction chemotherapy by the investigators group (not yet published) could improve survival in NPC. It encourage us to conduct this clinical trial.
Nasopharyngeal carcinoma (NPC) differs from other head and neck malignancies in terms of its epidemiology, pathology, and treatment outcome . It is endemic in China and is one of the major public health problems. Concurrent radiotherapy and chemotherapy is the primary treatment for patients with NPC. Despite such aggressive treatment, many patients with locally advanced NPC still develop locally recurrent disease. Since local control is directly related to patient morbidity and mortality in NPC, there is a strong need to identify methods to further improve treatment outcome for NPC. One strategy to improve local control is to escalate the dose of radiotherapy. This is because local control has been shown to be directly related to the radiotherapy dose. Several different techniques, including brachytherapy, stereotactic radiosurgery, and dose-painting intensity modulated radiotherapy (IMRT), have been used to increase radiotherapy dose. However, due to the large number of critical anatomic structures near the nasopharynx, dose-escalation in NPC can also lead to increased toxicities. One technique that has achieved dose-escalation with minimal increase in toxicity is simultaneous modulated accelerated radiation therapy (SMART). The main challenge for such treatment is to identify the appropriate tumor volume to receive the high-dose radiotherapy. Conventional dose-escalation is conducted using computed tomography (CT) to identify the gross tumor volume (GTV). However, recent progress with F-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in treatment planning allows more accurate tumor volume delineation. We hypothesize that the use of PET/CT in treatment planning can improve dose-escalation radiotherapy for NPC which in turn can improve therapeutic efficacy while reducing toxicity. PET/CT imaging of tissue hypoxia using [F-18]fluoromisonidazole (FMISO), the most widely used nitroimidazole imaging agent.Given that there has been no clinical trials directly comparing conventional chemoradiotherapy to CT-guided dose-escalation chemoradiotherapy or PET/CT guided dose-escalation chemoradiotherapy in locally advanced NPC.This was a study to evaluate the role of FMISO-PET hypoxia imaging for predicting survival in NPC,our study aims to compare the local control, overall survival and toxicities of the three treatment regimens..
This is a lead-in dose escalation study to determine the safety, tolerability, pharmacokinetics, maximum tolerated dose (MTD), and recommended Phase II dose of OPB-51602 administered on a weekly basis in subjects with advanced malignancies. Using the recommended phase II dose, the efficacy and tolerability of OPB-51602 administered prior to definitive chemoradiotherapy will be evaluated in locally advanced NPC patients. This study's overarching goal is the development of STAT3 inhibitors as a novel class of anti-cancer agents and the optimization of patient selection for STAT3 inhibitor therapy through parallel biomarker studies. This study hopes to establish a therapeutic window for OPB-51602 in solid tumours and will evaluate its potential as a targeted therapy of NPC, since this represents a critical unmet clinical need. The development of predictive and pharmacodynamic biomarkers in tandem with the clinical evaluation of OPB-51602 will be crucial to its therapeutic advancement and will enable an understanding of the genetic contexts of responsiveness and resistance to OPB-51602, which can in turn lead to the development of effective drug combinations to overcome resistance.The study hypothesizes that OPB-51602, a first-in-class STAT3 inhibitor, is efficacious in solid tumours with constitutively activated STAT3, such as NPC.
The purpose of this study is to evaluate whether dietary nitrate supplementation could improve the plasma nitrate levels for nasopharyngeal carcinoma patients receiving concurrent chemo-radiation therapy.
This phase I/II trial studies the side effects and the best dose of sorafenib tosylate and docetaxel when given together with cisplatin and to see how well they work in treating patients with recurrent or metastatic squamous cell carcinoma of the head and neck. Drugs used in chemotherapy, such as cisplatin and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Sorafenib tosylate may also help cisplatin and docetaxel work better by making tumor cells more sensitive to the drugs. Giving sorafenib tosylate, cisplatin, and docetaxel may be an effective treatment for squamous cell carcinoma of the head and neck.
Patients with head and neck cancer who underwent irradiation have a higher risk of developing severe carotid stenosis, and eventually develop to transient ischemic attack or stroke. However, it's still not clear whether early intervene in vascular risk factors is benefit for patients after radiotherapy. Our study aimed to evaluate the feasibility and safety of atorvastatin for preventing NPC patients after radiotherapy from severe carotid stenosis. In a randomized, double-blind, placebo-controlled trial, about 324 nasopharyngeal carcinoma (NPC) patients will be enrolled from six centers in Guangdong Province and randomized 1:1 to atorvastatin group or placebo group.
The present study is a randomized, control, phase II study of locally advanced nasopharyngeal carcinoma (NPC) treated with Gemcitabine plus cisplatin regimen (GP) or Docetaxel，cisplatin regimen plus 5-Fluorouracil (TPF) induction chemotherapy followed by concurrent chemoradiotherapy.
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.
