PURPOSE: The recurrent laryngeal nerve lymph nodes (RLN LNs) are among the most common metastatic sites in esophageal cancer, and the dissection of these lymph nodes (LNs) is considered beneficial. The purpose of this study was to evaluate the characteristics of RLN LN metastases from esophageal squamous cell carcinoma, and the effects of these metastases on the prognosis of patients. In addition, we aimed to determine the reasonable range of dissection of regional LNs. METHODS: The clinical data from 348 patients who underwent resection for esophageal carcinoma were retrospectively analyzed...

Human papilloma virus (HPV) is a known cause of cervical cancer, squamous cell carcinoma and laryngeal cancer. Although treatments exist for HPV-associated malignancies, patients unresponsive to these therapies have a poor prognosis. Recent findings from vaccine studies suggest that T-cell immunity is essential for disease control. Because Epstein-Barr Virus (EBV)-specific T cells have been highly successful in treating or preventing EBV-associated tumors, we hypothesized that the development of a manufacturing platform for HPV-specific T cells from healthy donors could be used in a third-party setting to treat patients with high-risk/relapsed HPV-associated cancers...

OBJECTIVE Awake craniotomies have become a feasible tool over time to treat brain tumors located in eloquent regions. Different techniques have been applied in neurooncology centers. Both "asleep-awake-asleep" (asleep) and "conscious sedation" were used subsequently at the authors' neurosurgical department. Since 2013, the authors have only performed conscious sedation surgeries, predominantly using the α2-receptor agonist dexmedetomidine as the anesthetic drug. The aim of this study was to compare both mentioned techniques and evaluate the clinical use of dexmedetomidine in the setting of awake craniotomies for glioma surgery...

PURPOSE: Aberrant fibroblast growth factor receptor (FGFR) expression is thought to contribute to the development of many types of cancer. As yet, however, their impact on the course and prognosis of head and neck cancer remains to be determined. Here, we aimed to investigate the effects of expression of the FGFR family members FGFR1 and FGFR3, as well as their downstream PI3K/AKT signal-regulated kinases, on the aggressiveness and prognosis of laryngeal cancer. METHODS: In total 137 surgically removed squamous cell laryngeal cancer (SCLC) and 100 matched non-cancerous laryngeal mucosa (NCLM) samples were assessed for mRNA expression using quantitative real-time PCR...

Objective: Staging of laryngeal cancer largely depends on cartilage invasion. Presence of cartilage invasion affects treatment choice and prognosis. On MRI and contrast-enhanced CT (CECT) it may be challenging to differentiate cartilage invasion from inflammation. The purpose of this study is to compare the diagnostic properties of dynamic contrast-enhanced CT (DCECT) and CECT for visual detection of cartilage invasion in laryngeal cancer. Study Design: Prospective cohort study...

Definitive concomitant chemoradiotherapy (CRT) with high-dose cis-platinum (CDDP) is a current standard protocol for advanced laryngeal and hypopharyngeal cancer sparing surgery for salvage. However, this modality is associated with limited feasibility and frequent sever toxicities. In the present study, a 'chemoradioselection' protocol with minimal toxicity was developed using initial response to CRT as a biomarker for patient selection. Between 2000, March and 2012, September 123 patients with stage III (44), IV (79) laryngeal (64) and hypopharyngeal carcinoma (59) excluding T4 cases were enrolled to this protocol...

Due to the lack of a definite diagnosis, a frequent recurrence rate and resistance to chemotherapy or radiotherapy, the clinical outcome for patients with advanced laryngeal cancer has not improved over the last decade. Annexin A2 is associated with the invasion and metastasis of cancer cells. In the present study, it was demonstrated using differential proteomics analysis that Annexin A2 is highly expressed in laryngeal carcinoma tissues and this was confirmed using immunohistochemistry, which demonstrated that the expression of Annexin A2 in laryngeal carcinoma tissues was significantly higher than in healthy adjacent tissue...

There is growing evidence that laryngeal cancers are responsive to sex hormones, specifically 17β-estradiol (E2), despite controversy regarding the presence and characterization of E2 receptors (ER). Determination of sex hormone responsiveness impacts the prognosis of laryngeal cancer patients and the treatment modalities implemented by their clinicians. Discovery of membrane-associated steroid hormone receptors and rapid membrane signaling opened the possibility that cancers previously labeled 'non-hormone dependent' and 'ER negative' might in fact be susceptible to the effects of E2 via these membrane receptors...

E-cadherin, β-catenin and Snail are important molecules involved in cellular adhesion and epithelial-mesenchymal transition. Loss of E-cadherin expression, nuclear relocation of β-catenin and high expression of Snail are connected to tumor progression, rapid cell growth and metastasis. The aim of our study was to analyze the immunohistochemical expression of β-catenin, E-cadherin and Snail, depending on clinico-morphological aspects of the laryngeal squamous cell carcinomas. Our results revealed variable E-cadherin, β-catenin and Snail expression, depending on differentiation degree and tumor stage...
