BACKGROUND: The role of neoadjuvant chemotherapy (NACT) for locoregionally advanced nasopharyngeal carcinoma (NPC) is unclear. We aimed to evaluate the feasibility and efficacy of NACT followed by concurrent chemoradiotherapy (CCRT) versus CCRT alone in locoregionally advanced NPC. METHODS: Patients with stage III-IVB (excluding T3N0-1) NPC were randomly assigned to receive NACT followed by CCRT (investigational arm) or CCRT alone (control arm). Both arms were treated with 80 mg/m(2) cisplatin every 3 weeks concurrently with radiotherapy...

The effectiveness of neoadjuvant chemotherapy (NACT) followed by concurrent chemoradiotherapy (CCRT) compared with CCRT alone in nasopharyngeal carcinoma (NPC) patients who presented with cervical nodal necrosis (CNN) is unknown. A total of 792 patients with stage T1-4N1-3M0 NPC and presented with CNN based on magnetic resonance imaging were retrospectively reviewed. Propensity score matching method was used to balance treatment arms for baseline characteristics. Eventually, 508 patients were propensity-matched on a 1:1 basis to create two groups (NACT + CCRT and CCRT groups)...

BACKGROUND: Potential clinical application values of certain cytokines and chemokines that participate in the process of tumor growth, invasion, and metastasis have been reported. However, there still lack of biomarkers for a great many of malignancy. This study identified cytokines or chemokines involved in the occurrence and development of nasopharyngeal carcinoma (NPC), which might be a biomarker for noninvasive early diagnosis. METHODS: The plasma levels of 19 cytokines and chemokines were detected by the luminex liquid array-based multiplexed immunoassays in 39 NPC patients before and after treatment by definitive intensity-modulated radiotherapy (IMRT)...

Grifolin, a natural product isolated from the mushroom Albatrellus confluens, has been reported to be a potent anti-cancer agent in nasopharyngeal carcinoma and osteosarcoma. The data obtained in this study revealed that grifolin is capable of inhibiting the growth and invasion of gastric cancer cells by inducing apoptosis and suppressing the ERK1/2 pathway. Our results support the potent utility of grifolin as an anti-tumor lead compound against gastric cancer cells.

The renin-angiotensin system (RAS) is a principal determinant of arterial blood pressure and fluid and electrolyte balance. RAS component dysregulation was recently found in some malignancies and correlated with poor patient outcomes. However, the exact mechanism of local RAS activation in tumors is still unclear. Here, we find that the local angiotensin II predominantly exists in the hypoxic regions of tumor formed by nasopharyngeal carcinoma CNE2 cells and breast cancer MDA-MB-231 cells, where these tumor cells autocrinely produce angiotensin II by a chymase-dependent rather than an angiotensin converting enzyme-dependent mechanism...

Therapy against nasopharyngeal carcinoma (NPC) is hurdled by chemoresistance. Recent studies found that microRNA (miRNA) are important regulators of cancer resistance. In this study, we aimed to explore the role and mechanism of miR-26b in regulating NPC cisplatin (CDDP) resistance. Real-time PCR was used to evaluate miR-26b levels in CDDP-resistant and CDDP-sensitive NPC cells, as well as human NPC tissues. MiR-26b was ectopically overexpressed in CDDP-resistant cells, followed by monitoring changes in cell viability and apoptosis...

BACKGROUND: Due to improvements in imaging and radiological techniques as well as the use of chemotherapy, distant metastasis has become the predominant mode of treatment failure in patients with locally advanced nasopharyngeal carcinoma (LA-NPC). Platinum-based systemic chemotherapy has shown survival benefits and is now the standard strategy for systemic therapy in patients with LA-NPC. Notably, the third-generation platinum reagent lobaplatin has shown anti-tumor effects in several solid tumors with lower incidences of gastrointestinal, hepatic and renal toxicity relative to other platinum drugs...

Formin-like 3 (FMNL3) plays a crucial role in cytoskeletal mediation and is potentially a biomarker for cell migration; however, its role in cancer metastasis remains unknown. In this study, we found elevated FMNL3 protein expression in clinical nasopharyngeal carcinoma (NPC) tissues. FMNL3 expression positively correlated to the clinical stage, T (tumour), N (lymph node metastasis) and M (distant metastasis) classification of NPC patients. Moreover, FMNL3 positively correlated to Vimentin expression and negatively correlated to E-cadherin expression in clinical NPC samples...

Pituitary adenomas presenting in uncommon anatomical locations are commonly misdiagnosed. Dramatic clinical presentation with hemorrhage and infarction, along with a lack of endocrine symptoms may further confound the diagnosis in some patients as illustrated in one of our two previously reported cases of non-small cell neuroendocrine carcinoma of the sinonasal tract and nasopharynx. This report presents the clinical progress of case number 2, which has a revised diagnosis of giant lactotroph pituitary adenoma...

BACKGROUND: Nasal stenosis is a rare but significant complication of chemoradiation treatment for nasopharyngeal carcinoma. It can cause distressing obstructive symptoms for the patient and potentially interfere with monitoring for recurrence. Quality-of-life indicators are known to be very poor in this group of patients; however, there is very little evidence in the literature as to management of this complication. METHODS: This paper presents an endoscopic day-case surgical procedure to address total posterior nasal stenosis, as conducted in three patients, which involves division of adhesions and removal of the posterior septum and posterior inferior turbinates, without the need for packing or stenting...

Metastases to breast are much rarer than primary breast tumors. We now present a case of 45-year-old female, who presented with an isolated breast mass. A positron emission tomography-computed tomography (PET-CT) done revealed hypermetabolic right breast nodules, soft tissue deposits, and multiple nodal involvement. The biopsy from the breast and axillary lymph node showed dense lymphoid infiltrate and was interpreted initially as granulomatous inflammation. However, the lumps were hard and suspicious for primary breast cancer, so an immunohistochemistry for cytokeratin was performed which highlighted the epithelial cell clusters masked within the inflammatory infiltrate and the diagnosis of undifferentiated carcinoma, lymphoepithelioma-like was made...

Capecitabine, an oral 5-fluorouracil prodrug, is currently used in the treatment of metastatic colorectal carcinoma and breast cancer. Fingerprints, also referred to as dermatoglyphics and characterized by the pattern of ridges and furrows on the fingertips, are used for identification by government agencies and personal electronic devices. Two women with breast cancer who were treated with capecitabine and developed drug-associated loss of their fingerprints are described. PubMed was used to search the following terms separately and in combination: absence, adermatoglyphia, breast, cancer, capecitabine, carcinoma, colon, colorectal, dermatoglyphics, fingerprint, fluorouracil, foot, hand, loss, malignancy, nasopharyngeal, oncology, reaction, rectal, skin, syndrome, tumor, and xeloda...

Argininosuccinate synthetase 1 (ASS1), the rate-limiting enzyme for arginine biosynthesis, is expressed in many types of human malignancies. Recent studies showed that ASS1 may have tumor suppressor function and that ASS1 deficiency is associated with clinical aggressiveness in nasopharyngeal carcinoma, myxofibrosarcomas and bladder cancer. The goal of this study was to evaluate the prognostic impact of ASS1 expression in patients with pancreatic ductal adenocarcinoma (PDAC). Our study included two independent cohorts: untreated cohort, which was comprised of 135 patients with PDAC who underwent pancreatoduodenectomy (PD) without pre-operative neoadjuvant therapy, and treated cohort, which was comprised of 122 patients with PDAC who have completed neoadjuvant therapy and PD...

DNA-dependent protein kinase catalytic subunit (DNA-PKcs) is a distinct factor in the non-homologous end-joining (NHEJ) pathway involved in DNA double-strand break (DSB) repair. We examined the crosstalk between key proteins in the DSB NHEJ repair pathway and cell cycle regulation and found that mouse embryonic fibroblast (MEF) cells deficient in DNA-PKcs or Ku70 were more vulnerable to ionizing radiation (IR) compared with wild-type cells and that DSB repair was delayed. γH2AX was associated with phospho-Ataxia-telangiectasia mutated kinase (Ser1987) and phospho-checkpoint effector kinase 1 (Ser345) foci for the arrest of cell cycle through the G2/M phase...
