Vascular endothelial growth factor (VEGF) is a potent stimulator of endothelial cell proliferation. It has been implicated in tumor growth of human thyroid carcinomas. Using the VEGF immunohistochemistry staining score, we correlated the level of VEGF expression with the metastatic spread of 19 cases of thyroid papillary carcinoma. The VEGF immunostaining(More)
PURPOSE The detection of an infraclinical primary by tonsillectomy in case of cervical lymph node of an epidermoid carcinoma with unknown primary after a radical neck dissection, allows avoiding irradiation of the normal larynx. The aim of this study is to quantify the rate of tonsil primary to justify this procedure. METHODS AND MATERIALS From 1969 to(More)
Angiogenesis is implicated in several pathological conditions, such as inflammation and tumor growth. Vascular endothelial growth factor (VEGF), also known as vascular permeability factor, is a potent stimulator of endothelial cell proliferation in vitro and in vivo. The present work aimed to compare VEGF expression in human normal thyroid glands,(More)
Surgical resection is often required for maxillary cancer, producing a communication between the oral cavity and the nose or paranasal sinuses. After maxillectomy, patients experience major dysfunction in speech and swallowing which have a very negative psychological effect. These problems can be overcome with an immediate prosthesis but to be fully(More)
AIMS To understand management strategies and outcomes of patients diagnosed with a head and neck tumour and a synchronous second cancer developed at another anatomic site. MATERIALS AND METHODS Retrospective analysis of all patients diagnosed with a head and neck carcinoma and a synchronous cancer and engaged in curative-intent treatments. To evaluate(More)
BACKGROUND AND PURPOSE Endoscopic endonasal surgery let us observe that woodworkers' nasal adenocarcinomas originate in the olfactory cleft. Our aim was the identification of CT imaging features that corroborate the olfactory cleft as the site of origin for woodworkers' adenocarcinoma. MATERIALS AND METHODS We designed a retrospective study to compare CT(More)
The olfactory cleft is a narrow chamber located under the cribriform plate and between the turbinate wall of the ethmoidal labyrinth and the corresponding nasal septum. Nasal adenocarcinomas are mostly described as originating in the ethmoid sinus and operated via external approaches. We designed a prospective study on twenty consecutive woodworkers'(More)
PURPOSE To evaluate the efficacy of postoperative brachytherapy alone (brachy) for Stage T1-2 squamous cell carcinomas (SCC) of the floor of mouth (FM) and the oral tongue (OT) with close or positive margins. METHODS AND MATERIALS Between 1979 and 1993, 36 patients with T1-2 N0 (24 T1, 12 T2) OT (19), and FOM (17) SCC with close or positive margins(More)
INTRODUCTION Small cell neuroendocrine carcinoma (SNEC) of the sinonasal tract is a rare disease. OBJECTIVE Report a descriptive study of a relatively large cohort of SNEC of the nasal cavity and paranasal sinuses. METHOD The medical records of 21 patients presenting with nasal and paranasal SNEC to various French hospitals, from 1989 to 2003, were(More)
