The exact cause of nasopharyngeal cancer is unknown, but a number of factors can increase your risk of developing the condition. Specifically, the later the N stage is, the worse the prognosis is. Non-keratinizing undifferentiated carcinoma (the most common type in the … 651 Dongfeng Road East, 510060 Guangzhou, China (e-mail: guoxiang@sysucc.org.cn) and … 3 The primary … Nasopharyngeal carcinoma (NPC) exhibits a distinctive racial and geographic distribution. Thus, the main purpose of our study was to investigate the metastasis patterns of different histological types of NPC and to clarify the prognostic characteristics of metastases at different sites. Int J Radiat Oncol Biol Phys 2001;50:717-26. Most nasopharyngeal cancers are nasopharyngeal carcinoma.There are three types of nasopharyngeal cancer: . … 1 There were approximately 42,100 new cases of NPC in China in 2013, accounting for 1.14% of all new cancer cases in China. Salvage Endoscopic Nasopharyngectomy in Recurrent Nasopharyngeal Carcinoma: Prognostic Factors and Treatment Outcomes. We evaluated clinical characteristics and treatment outcomes of nasopharyngeal carcinoma and assessed prognostic factors related to survival. Currently, the features and prognosis of nasopharyngeal carcinoma (NPC) with distant metastases are still rarely reported. We evaluated clinical characteristics and treatment outcomes of nasopharyngeal carcinoma and assessed prognostic factors related to survival. Long term complications and prognostic factors in locally advanced nasopharyngeal carcinoma treated with docetaxel, cisplatin, 5-fluorouracil induction chemotherapy followed by concurrent chemoradiotherapy: A retrospective cohort study. Nasopharyngeal carcinoma (NPC), or nasopharynx cancer, is the most common cancer originating in the nasopharynx, most commonly in the postero-lateral nasopharynx or pharyngeal recess (fossa of Rosenmüller), accounting for 50% of cases.NPC occurs in children and adults. (A) We applied NMF (k = 5 factors or expression patterns) to analyze the gene expression profiles of nasopharyngeal carcinoma (NPC) samples in the training cohort (n = 113). Radiation therapy or concurrent chemoradiation therapy is mainstay for treatment of nasopharyngeal carcinoma. Extended-field radiotherapy for patients with nasopharyngeal carcinoma might contribute to improving their cure-rate, and precise radiation planning is warranted to avoid the late complications such as hearing loss.
