BACKGROUND: Enlarged retropharyngeal lymph nodes (RLNs) are very common in patients with nasopharyngeal carcinoma (NPC) undergoing radiotherapy. The most suitable treatment option for enlarged RLNs depends on the pathological results. However, RLN sampling is difficult and imminent in the clinic setting. We recently developed a novel minimally invasive technique termed endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for sampling RLN tissues sufficient for pathological or cytological diagnosis...

PURPOSE: In nasopharyngeal cancer, brachytherapy is given as boost in primary treatment or as salvage for recurrent or persistent disease. The Rotterdam nasopharyngeal applicator (RNA) allows for suboptimal reduction of soft palate radiation dose, based on image-guided brachytherapy plans. Building on the RNA, we propose a novel design, the Benavides nasopharyngeal applicator (BNA). METHODS AND MATERIALS: The virtual BNA was reconstructed on two cases (one T1, one T2) previously treated with intracavitary brachytherapy using the RNA...

The ototoxic effects of radiotherapy have been poorly characterized. We examined adult survivors of childhood cancer who were treated with radiotherapy, which included the head, before the age of 22 years and between 1952 and 2016. Those who received platinum chemotherapy were excluded. Demographic, diagnosis, and treatment outcomes were captured. Audiograms were graded using the Chang and International Society of Paediatric Oncology ototoxicity (SIOP) scales. Among 276 patients with a history of radiation to sites that included the brain, orbit, nasopharynx, and total body irradiation, the median age at treatment was 10...

BACKGROUND: The incidence of pediatric head and neck cancer (PHNC) is increasing worldwide, especially when compared with childhood cancer in general. However, there is still a lack of knowledge about the demographic profile of such patients across the globe. Therefore, the aim of this study was to describe demographic, topographic and histopathological features of pediatric head and neck cancer patients from a single Brazilian institution. METHODS: Medical records were retrospectively reviewed for all cancer cases diagnosed from 1986 to 2016 affecting patients aged 19-years and younger...

Epstein-Barr virus (EBV) can establish a life-long latent infection in the host and is associated with various human malignancies, including nasopharyngeal carcinoma (NPC), the most common cancer originated from nasopharynx. EBV nuclear antigen 1 (EBNA1) is the only viral protein absolutely demanded for segregation, replication, transcription and maintenance of EBV viral genome in host cells. Baicalein, a bioactive flavonoid compound purified from the root of Scutellariae baicaleinsis, displays anti-inflammatory, immunosuppressive, and anti-tumor properties...

Identification of the specific protein target(s) of a drug is a critical step in unraveling its mechanisms of action (MOA) in many natural products. Curcumol, isolated from well known Chinese medicinal plant Curcuma zedoary, has been shown to possess multiple biological activities. It can inhibit nasopharyngeal carcinoma (NPC) proliferation and induce apoptosis, but its target protein(s) in NPC cells remains unclear. In this study, we employed a mass spectrometry-based chemical proteomics approach reveal the possible protein targets of curcumol in NPC cells...

The population of cancer survivors with prior cancer is rapidly growing. Whether a prior cancer diagnosis interferes with outcome is unknown. We conducted a pan-cancer analysis to determine the impact of prior cancer history for patients newly diagnosed with cancer. We identified 20 types of primary solid tumors between 2004 to 2008 in the Surveillance, Epidemiology, and End Results (SEER) database. Demographic and clinicopathologic variables were compared by chi-squared test and t-test as appropriate. The propensity score-adjusted Kaplan-Meier method and Cox proportional hazards models were used to evaluate the impact of prior cancer on overall survival (OS)...

The aim of this study was to investigate the potential of jaw tracking with the volumetric-modulated arc therapy (VMAT) to reduce the normal tissue dose. Plans of nasopharynx, lung, and prostate cancers (10 plans for each) were used to perform VMAT with and without jaw tracking. The dose reduction was evaluated in terms of organ doses and integral doses. Organ-dose reduction with jaw tracking was statistically significant in the volume receiving a dose of 5 Gy (V5 ) of bladder, rectum, and lung, the volume receiving a dose of 10 Gy (V10 ) of bladder, rectum, and lung, and the mean dose of lung ( P < 0...

Nasopharyngeal carcinoma (NPC), which arises from the nasopharynx epithelium, is most common in Southeast Asia, particularly in Southern China. To date, a variety of microRNAs have been demonstrated to serve key functions in the progression and development of NPC. microRNA-425 (miR-425) has previously been reported to be frequently abnormally expressed in a number of different types of human cancer, including lung, gastric, cervical, breast and prostate cancer. However, to the best of our knowledge, the expression patterns, functions and underlying mechanisms of miR-425 in NPC remain largely unexplored...

OBJECTIVE: The utility of fluorodeoxyglucose positron emission tomography (FDG-PET) imaging to predict outcome has been well-established for patients undergoing definitive radiation in the initial management of head and neck cancer. However, the usefulness of this modality in the recurrent setting remains uncertain. We sought to evaluate the prognostic value of metabolic tumor parameters measured on FDG-PET in patients treated by reirradiation for recurrent head and neck cancer. METHODS: Thirty-four tumors occurring in 29 patients were reirradiated and were evaluable...

BACKGROUND: The increasing incidence of oropharyngeal squamous cell cancer (OPSCC) is well established. However, up-to-date incidence estimates and trends for head and neck squamous cell cancers (HNSCCs) overall, including major anatomic sites, and nonoropharyngeal (non-OP) HNSCCs by sex, race, and age in the United States are not well described. METHODS: A retrospective analysis of incident HNSCCs during 1992 through 2014 using the Surveillance, Epidemiology, and End Results database was performed to evaluate the incidence of HNSCCs overall, OPSCC, and non-OP HNSCC (those of the larynx, oral cavity, hypopharynx, nasopharynx, and nasal cavity)...

REVIEW
JingJing Wu, Swei Sunny Hann
Nasopharyngeal carcinoma (NPC) is one of the most common cancers originating in the nasopharynx and occurring at high frequency in South-eastern Asia and North Africa. Long non-coding RNAs (lncRNAs) are a class of non-protein-coding RNA molecules and key regulators of developmental, physiological, and pathological processes in humans. Emerging studies have shown that lncRNAs play critical roles in tumorgenicity and cancer prognosis. With the development of deep sequencing analyses, an extensive amount of functional lncRNAs have been discovered in nasopharyngeal carcinoma tissues and cell lines...
