“…In the literature, there exist only a few publications on the exclusive use of NBI in laryngology (135)(136)(137)(138)(139)(140)(141)(142). However, several studies assessed the value of NBI in the head and neck also including the larynx (132,137,(143)(144)(145)(146)(147)(148). NBI has shown in the larynx, over last years, improved sensitivity 61-91% and specificity 87-92% (146,149) but false positives and false negatives have been reported, especially in the larynx, and increase with a short learning curve.…”

Abstract.Background: Multi-step cancerogenesis guides laryngeal cancer onset and it includes a wide variety of pre-cancerous lesions that are macroscopically challenging to identify and distinguish from initial cancerous foci. Since the treatment of laryngeal cancer and its precursor lesions has a great impact on important laryngeal basic functions, early detection and preoperative assessment are important for a curative and function-preserving therapy. Nowadays, despite the high number of more advanced diagnostic techniques and methods, unfortunately, it is not uncommon for different clinicians to use different nomenclature or to identify different stage for the same laryngeal lesion. From these observations, it is obvious that an instrument offering the possibility to detect precancerous lesions, early cancerous lesions, and satellite foci or second primaries would be the key to improving management and outcome in laryngeal patients. Object. Different modalities of diagnostic techniques of laryngeal lesions exist. Rather than difference between benign and obvious malignant diseases, more difficult is to detect the presence of precancerous epithelial alterations. Not all tests achieve the same diagnostic accuracy, hence this meta-analysis of literature aimed to synthesize the validity of each single diagnostic technique in identifying and staging laryngeal disease. Methods: A systematic review of literature was led searching for articles mentioning the following terms including their various combinations to maximize the yield: larynx, laryngeal precancerous lesions, laryngeal cancer, white light (WL) endoscopy, stroboscopy, contact endoscopy (CE), autofluorescence (AF), ultrasound (US), narrow band imaging (NBI), computed axial tomography (CAT), magnetic resonance imaging (MRI), positron emission tomography (PET), CAT/PET. Then, a quantitative analysis was carried on for paper published after 2005 onward, reporting a minumun series of 10 patients each study, declaring sensitivity and specificity of each diagnostic system. Results: The search identified 7215 publications, of which 3616 published after 2005, with a final results of a total of 214 articles stratified and included by our selection criteria. 42 out of 214 articles were selected for quantitative synthesis. 25 out of 41 studies had a quality score of ≥ 6 (good), 16 presented a score between 4 and 5 (fair). While objections can be raised about the pooling of different diagnostic procedures under the same group and the high level of heterogeneity in the meta-analyses, the inclusion of over 4400 laryngeal lesions makes the results fairly robust. Conclusions: A comprehensive overview of the most recent advances in laryngeal imaging technology combined with all of the information needed to interpret findings and successfully manage patients with voice disorders can be found herein. With these data, clinicians can riskstratify patients and select proper examination modalities in order to provide appropriate care. Moreover, study limitations, together with p...

“…Watanabe et al (8,9) reported that the NBI rhinolaryngoscope (ENF-V2, Olympus Medical Systems) with a colourchip light source (CLV-160B, Olympus Medical Systems) improved the diagnostic accuracy, and the negative predictive values for superficial lesions in the oropharynx and hypopharynx compared with those of conventional WLI. However, there is still a critical difference in the image qualities of CCDs between gastrointestinal endoscopy and rhinolaryngoscopy.…”

Endoscopy is essential for the diagnosis and treatment of cancers derived from the gastrointestinal tract. However, a conventional white-light image has technical limitations in detecting small or superficial lesions. Narrow-band imaging, especially with magnification, allows visualization of microstructure patterns and microvascular patterns on the mucosal surface. These technical breakthroughs enable endoscopists to easily detect small pre-neoplastic and neoplastic lesions and to make a differential diagnosis of these lesions. Appropriate diagnosis with narrow-band imaging contributes to minimally invasive endoscopic resection.

“…The NBI system (Olympus Medical System Co., Tokyo, Japan) has been already proven to be a useful diagnostic tool for identifying superficial squamous cell carcinoma of the head and neck [4][5][6][19][20][21]. Trans-nasal endoscopy can usually be performed comfortably due to attenuation of the gag reflex [22]; indeed in Japan, trans-nasal endoscopy is a very common procedure and can be performed without sedation.…”

The value of narrow band imaging endoscope for early head and neck cancers

Abstract: An NBI endoscope significantly improves diagnostic accuracy, sensitivity, and negative predictive value in detecting SCCHN in EC patients. This endoscope would be highly beneficial in detecting superficial SCCHNs in high-risk patients.
