Filter by:Serrated Polyposis Syndrome (SPS) is a high-risk condition for colorectal cancer (CRC). SPS patients have a cumulative CRC risk of 1.9% in 5 years despite a strict endoscopic surveillance in specialized centers. Proximal serrated lesions are endoscopically challenging to detect due to their unremarkable morphology. Endocuff is a novel device comprised of a cap with a row of finger-like projections with a unique dynamic shape that help to flatten mucosal folds during withdrawal of the instrument in order to improve detection of lesions. Recent studies have reported an increase of detection rate and mean per patient of adenomas with Endocuff-assisted Colonoscopy compared with Standard Colonoscopy. The purpose of this study is to assess the usefulness of Endocuff-assisted Colonoscopy to detect serrated lesions in SPS patients undergoing surveillance compared to Standard Colonoscopy in a randomized fashion
We define refractory nasopharyngeal carcinoma as the following: recurrence with radiation brain injury after radiotherapy, recurrence after the second or more courses of radiotherapy, standard treatment failure after recurrence, and first-line treatment failure after multiple distant metastasis. There is no standard treatment for refractory nasopharyngeal carcinoma. Platinum plus 5-Fu is the classic regimen for primary treatment of nasopharyngeal carcinoma. Endostatin is a multiple targeted angiogenesis inhibitor acting on tumor associated neovascular endothelial cells, normalizing the morphology and function of tumor vasculature, and indirectly leading to the quiescence or reduction of tumors. The purpose of this phase II clinical trial is to determine the efficacy and safety of nedaplatin plus continuous low dose 5-Fu intravenous infusion combined with endostar® (Recombinant Human Endostatin Injection) continuous intravenous infusion compared with nedaplatin plus continuous low dose 5-Fu intravenous infusion alone in refractory nasopharyngeal carcinoma. The study hypothesis is that nedaplatin plus continuous low dose 5-Fu intravenous infusion combined with endostar® continuous intravenous infusion is effective and safe in refractory nasopharyngeal carcinoma.
NBI has been proven to be a useful tool to detect early NPC, but they were few studies concerning the detection of post-radiotherapy mucosal residual NPC using NBI system
This study will assess the effectiveness of MEDIHONEY® sinus rinses (alone or in combination with intranasal corticosteroids) vs. intranasal corticosteroid sinus rinses on mucosal healing and polyp recurrence in the post-operative period following functional endoscopic sinus surgery.
The purpose of this study is to determine whether celecoxib is effective in the treatment of nasopharyngeal carcinoma by concurrent chemoradiation with weekly nedaplatin.
The purpose of this study is to evaluate the safety and efficacy of HepaSphere interventional therapy using digital subtraction angiography（DSA） for nasopharyngeal carcinoma.
This study aims to determine the safety and efficacy of expanded activated autologous NK cells administered after cetuximab in patients with EGFR-positive nasopharyngeal carcinoma or head and neck squamous cell carcinoma.
Nasopharyngeal carcinoma (NPC) is usually treated with chemoradiotherapy. While the effects of this treatment on cochlear function is well characterized, its effect on vestibular function is not well studied. In this study the investigators will study the vestibular function of 50 patients undergoing chemoradiotherapy for NPC both before and after treatment in order to better define its effects. All patients will undergo a validated questionnaire (dizziness handicap index), posturography, audiometry and vestibular-evoked myogenic potentials.
A circulating tumor cell (CTC) count is an established prognostic factor in some malignancies such as metastatic breast cancer. However, the value of CTC in diagnosis and outcome prediction of metastatic nasopharyngeal carcinoma (mNPC) patients is not unknown. Through the observational prospective clinical trial, sensitivity, specificity, positive and negative predictive values of CTC in diagnosis of mNPC patients will be gained. Further, the value of CTC in outcome prediction of mNPC patients will be uncovered.
The purpose of this study is to investigate the impact of different neoadjuvant chemotherapy schedules of cisplatin and 5-FU on acute toxicity, tumor response, and long-term survival in patients with advanced nasopharyngeal carcinoma
