Epidemiological Characteristics and Survival Analysis of Patients With Nasopharyngeal Cancer in Western Greece.

Purpose The purpose of this study is to assess the overall survival (OS) of patients with nasopharyngeal cancer and the factors affecting the survival rates. Methods A retrospective cohort study was performed, including 77 patients with nasopharyngeal cancer diagnosed and treated in the Otorhinolaryngology Clinic of the University Hospital of Patras during 1990-2017. The prognostic impact of age, gender, occupation, smoking/alcohol, and TNM staging were evaluated using Kaplan-Meier analysis.

High PINCH1 Expression in Human Laryngeal Carcinoma Associates with Poor Prognosis.

Focal adhesion signaling to actin cytoskeleton is critically implicated in cell migration and cancer invasion and metastasis. Actin-binding proteins cofilin and N-WASP regulate actin filament turnover, and focal adhesion proteins parvins and PINCH mediate integrin signaling to the actin cytoskeleton. Altered expression of these proteins has been implicated in human cancer.

HPV infection in oropharyngeal squamous cell carcinomas: correlation with tumor size.

Purpose: Human papillomavirus (HPV) is implicated in carcinogenesis of a variety of epithelia, including oropharyngeal and laryngeal. High risk (HR) HPV persistent infection in head and neck squamous cell carcinomas (HNSCC) is a significant event, but its influence regarding the prognosis and survival in these patients remains under consideration. Our aim was to analyze a series of oropharyngeal (OP) SCCs at the HPV DNA level, correlating them to the survival status of the corresponding patients.

A link between B expression and tumor progression in laryngeal cancer.

Laryngeal cancer is a frequent malignancy originating from the squamous vocal epithelium in a multi-stage fashion in response to environmental carcinogens. Although most cases can be cured by surgery and/or radiotherapy, advanced and relapsing disease is common, and biomarkers of such dismal cases are urgently needed. The cancer genome of laryngeal cancers was recently shown to feature a signature of aberrant nuclear factor (NF)-κB activation, but this finding has not been clinically exploited.

Deregulation of PTEN Expression in Laryngeal Squamous Cell Carcinoma Based on Tissue Microarray Digital Analysis.

Background/aim: Phosphatase and tensin homolog (PTEN) (gene locus: 10q23.3) -a tumor suppressor gene- is deleted, mutated or epigenetically hyper-methylated in a variety of malignancies. PTEN acts as a negative regulator in PI3K/AKT/mTOR signaling transduction pathway.

Topoisomerase I deregulation in laryngeal squamous cell carcinomas based on tissue microarray analysis.

Purpose: Topoisomerases (types: I/IIa-b/IIIa-b) represent a super-family of nucleic enzymes involved in the DNA replication, transcription, recombination, and also chromosome topological formation. Topoisomerase's I (Topo I- gene location: 20q12) aberrant expression is a frequent genetic event in a variety of solid malignancies. Topo I inhibition promotes cell death due to DNA damage and for this reason it is a target for specific targeted chemotherapy (camptothecin, topotecan, irinotecan).

mTOR deregulation in oral cavity squamous cell carcinoma.

Signal transduction pathways consist of a variety of inter- and intra-cellular molecules. They act as supporting mechanisms for cell survival and homeostasis. Among them, the phosphatidylinositol 3-kinase (PI3K)/tumor suppressor phosphatase and tensin homologue deleted on chromosome ten (PTEN)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) pathway plays a crucial role in regulating normal cell growth based on growth factor receptors (GFRs) interaction, including epidermal GFR (type II-HER2) and insulin GFR (IGF).

Horner's Syndrome Incidental to Medullary Thyroid Carcinoma Excision: Case Report and Brief Literature Review.

Horner's syndrome is characterized by a combination of ipsilateral miosis, blepharoptosis, enophthalmos, facial anhidrosis, and iris heterochromia in existence of congenital lesions. The syndrome results from a disruption of the ipsilateral sympathetic innervation of the eye and ocular adnexa at different levels. Though rare, thyroid and neck surgery could be considered as possible causes of this clinical entity.

Chronic rhinocerebral mucormycosis: a rare case report and review of the literature.

Rhinocerebral mucormycosis is an invasive infection caused by filamentous fungi of the Mucoraceae family. The rhinocerebral form of the disease represents the most common form and has two distinct clinical entities. The common presentation consists of a rapidly progressive infection with high mortality rate, while the other presentation is that of a chronic infection with lower mortality.

Extranodal nasal-type NK/T-cell lymphoma of the palate and paranasal sinuses.

Background: Extranodal nasal-type natural killer (NK)/T-cell lymphoma represents a rare entity, typically originating in the nasal cavity, palate or midfacial region. Signs and symptoms include non-specific rhinitis and/or sinusitis, nasal obstruction, epistaxis, facial swelling and development of deep necrotic ulceration in the midline of the palate, causing an oronasal defect. Differential diagnosis includes fungal infections, Wegener's granulomatosis, tertiary syphilis, other non-Hodgkin's lymphomas and malignant epithelial midline tumors.

Pharyngocutaneous fistula complicating laryngectomy: can metronidazole help?

Aim: To evaluate the use of metronidazole as a prophylactic agent against pharyngocutaneous fistula (PCF) formation.

Patients And Methods: Seventy patients who underwent total laryngectomy between 2000 and 2008 in our department were divided into two groups. The first group (M+ group) was placed on a 10-day metronidazole regimen (2 days prior to surgery and 7 days following).

MMP-2 expression in 102 patients with glottic laryngeal cancer.

In order to evaluate the potential of matrix metalloproteinase 2 (MMP-2) as a prognostic factor for glottic laryngeal cancer. One hundred and two surgical specimens from patients with glottic laryngeal cancer who underwent laryngectomy for their disease in the University Hospital of Patras, Greece from 1998 to 2005 were reviewed retrospectively regarding MMP-2 expression via immunohistochemistry. Immunostaining was performed using a streptavidin-biotin peroxidase complex technique (LSAB).

Laryngeal cancer and passive smoking: the neglected factor?

In the present paper we investigate the relationship of environmental tobacco smoke (ETS) exposure to laryngeal cancer. 209 patients who were diagnosed with laryngeal cancer from 2000 to 2009 at the University Hospital of Patras, Western Greece, were reviewed with regard to patient age, disease stage at presentation, tumor differentiation, tobacco product use, alcohol consumption, occupation, and ETS exposure in the working environment. Pearson Chi-square method was used to determine the effect of ETS exposure on cancer stage, TNM classification and tumor differentiation in the dichotomized population (exposed vs.

Survival after laryngectomy: a review of 133 patients with laryngeal carcinoma.

Survival trends in survival for laryngeal cancer in Europe are varied. Five-year survival varied around 60-64% but numbers below 50% have been commonly reported. The aim of this study was to assess the factors influencing survival in patients with laryngeal cancer in our region.

Low COX2 in tumor and upregulation in stroma mark laryngeal squamous cell carcinoma progression.

Objectives/hypothesis: Invasive squamous cell carcinomas (SCC) of the larynx, like most solid tumors, are surrounded by a reactive stroma, in which cancer associated fibroblasts (CAFs) are the predominant cell type. This mesenchymal reaction may affect cancer progression multiply. The proinflammatory enzyme cyclooxygenase-2 (COX-2) has been correlated with head and neck cancer.

Tuberculosis of the parotid gland.

Tuberculosis (Tbc) presented as an isolated parotid mass is rare. Preoperative diagnosis is difficult and the symptomatology is nonspecific. In the majority of the cases an initial diagnosis of a parotid tumor, often a pleomorphic adenoma, is made.

Glottic versus supraglottic tumors: differential molecular profile.

Glottis and supraglottis, although anatomically interconnected, are embryologically distinct. Moreover, squamous cell carcinomas arising from these subsites, differ in terms of epidemiology, risk factors, clinical behaviour and prognosis. This study aims to explore any possible differences between their molecular profiles.

Neurotoxicity of BFM-95 on the medial olivocochlear bundle assessed by means of contralateral suppression of 2f1-f2 distortion product otoacoustic emissions.

Objective: Berlin-Frankfurt-Munster 95 (BFM-95) is a common chemotherapeutic protocol against acute lymphoblastic leukemia (ALL). This prospective study investigates whether this protocol has an adverse effect on the medial olivocochlear bundle (MOCB) and/or outer hair cells' (OHCs) function. The distortion product otoacoustic emissions (DPOAEs) and their suppression by means of contralateral application of white noise were used for assessing the function of OHCs and the MOCB, respectively.

Cancer patients with large defects. Reconstructional options: a case study.

We report a case of a seventy-five years old male patient with a squamous cell carcinoma (SCC) originated from the right external ear four years ago. He was undergone surgical removal of the lesion with a combination of modified neck dissection and reconstruction with the use of pectoralis major flap. Furthermore, he had radiotherapy with 6000 rads of the right temporal region.

Matrix proteoglycans are markedly affected in advanced laryngeal squamous cell carcinoma.

Proteoglycans (PGs) are implicated in the growth and progression of malignant tumors. In this study, we examined the concentration and localization of PGs in advanced (stage IV) laryngeal squamous cell carcinoma (LSCC) and compared with human normal larynx (HNL). LSCC and HNL sections were examined immunohistochemically with a panel of antibodies, and tissues extracts were analyzed by biochemical methods including immunoblotting and high performance liquid chromatography (HPLC).

Rehabilitation after laryngectomy: a practical approach and guidelines for patients.

Background: Laryngectomy causes irreversible loss or distortion in basic human habits, such as speech, swallowing, smelling, tasting, coughing and kissing. Rehabilitation can help a patient to reach the maximal potential within the context of his or her social milieu. Learning and adapting the lifestyle of living after laryngectomy is a challenge that faces the patient and the doctor.
