Opis:
Introduction: Novel endoscopic technique – Narrow Band Imaging (NBI) seems to be a promising method for an early detection of neoplastic lesions of the upper aerodigestive tract. Compared to white light endoscopy, NBI improves the visualisation of the mucosal and submucosal microvascular patterns of observed pathologies. The aim of the study was to evaluate the diagnostic value of biopsy and NBI in patients with cancer of the larynx and hypopharynx. Material and methods: The study was conducted in 100 adult subjects hospitalized in the Clinic of Otolaryngology, Laryngological Oncology, Audiology and Phoniatrics of Military Medical Academy University Teaching Hospital in Lodz, who were planned for surgical procedures for excision or surgical biopsy of pathological lesions of the hypopharynx or larynx. The following examinations were performed: subjective and objective, otorhinolaryngological, NBI endoscopy and histopathological assessment of suspicious lesions. The microvascular pattern of observed lesions was assessed according to the Ni scale criteria. The next stage of the study was to compare the endoscopic examination results (type of vascular pattern according to the Ni scale) with the histopathological result. The obtained results were subjected to statistical analysis. Results: The sensitivity of NBI endoscopy in detection of malignant neoplasms in patients with hypopharynx and larynx lesions is 90.48%, specificity – 91.14%, positive predictive value – 73.08%, negative predictive value – 97.30%. C onclusions: NBI endoscopy is a modern imaging method, increasing the diagnostic potential of endoscopy in the early detection of malignant lesions within the hypopharynx and larynx.

Opis:
Introduction: The two major recognized risk factors for laryngeal cancer are tobacco and alcohol consumption. However, according to WHO and IARC, occupational factors are probably underestimated. Confirmed/highly probable occupational carcinogens related to laryngeal cancer include asbestos and strong organic acid mists. Probable carcinogens are cement, polycyclic aromatic hydrocarbons (PAH) and wood dust. Suspected carcinogens are organic solvents, formaldehyde, coal/silica dust, leather dust and cotton dust. An important problem of epidemiological studies appears to be the lack of differentiation between laryngeal and hypopharyngeal (squamous cell) carcinomas. Material and Methods: For the purposes of this study, a database of 164 well-documented cases of laryngeal and hypopharyngeal cancers was created by collecting data from 4 centres in Belgium, Italy and France. In order to identify confirmed, probable and suspected carcinogenic risks, jobs and exposures over the whole career of the patients were exhaustively identified and mapped. Confounding factors were taken in account. Results: In general, occupational exposure to known or suspected carcinogens is significantly higher in laryngeal than in hypopharyngeal carcinomas. As regards the exposed subjects, the global occupational exposure profiles differ significantly (10 categories). Asbestos and acid mist exposures are significantly more important in laryngeal carcinoma. Coal/silica dust exposure is significantly more important in pharyngeal carcinoma..
