“…This is an extremely rare tumour, accounting for less than 1% of all laryngeal cancers [21]. One description of the appearance of the neuroendocrine tumour seen in NBI is given in the literature, concerning the lesion localised in the intestinal lumen [22] and in the area of the head and neck [19]. The authors have not observed any characteristic vascularisation that confirms the malignant nature of the lesion.…”

“…Rare laryngeal cancers do not have their own fixed vascular pattern characteristic for Narrow Band Imaging endoscopy. So far only Nonaka et al [20] and Valls-Mateus et al [19] have described sarcoma cases in NBI. It is a raised, well-vascularised lesion, which does not have characteristic capillary loops.…”

“…These cases concern mainly the gastrointestinal tract [23][24][25]. In otorhinolaryngology, only Valls-Mateus et al [19] referred to this issue. According to them, lymphomas of the head and neck do not show any specific vascularisation available in NBI examination when compared to changes located in the gastrointestinal tract.…”

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%. CONCLUSIONS: 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.

“…Four of the five included studies reported measures of NBI diagnostic accuracy between LP and LSCC [ 7 , 10 , 12 , 13 ]. Studies were consistent to confirm high SE of NBI both for LP (92–94%) and LSCC (92–100%), better for the latter.…”

Narrow-band imaging (NBI) represents a valid aid in laryngeal squamous cell carcinoma (LSCC) diagnosis for detecting vascular changes. However, LSCC and laryngeal papillomatosis (LP) show similar vascular patterns that may lead to misdiagnosis and improper treatment. This review aims to deepen this NBI limit in order to stress a careful preoperative evaluation of laryngeal lesions. The research was carried out on PubMed, Web of Science and Scopus databases using specific keywords. The topic of research was assessed by these parameters: accuracy, sensitivity, specificity, and positive and negative predictive values. This review included only five articles: they demonstrated that NBI is better than white-light endoscopy in detecting LSCC and LP. They also reported that LP is frequently mistaken for LSCC, resulting in high rates of false positives using NBI. This is the first review that emphasized this NBI limitation in distinguishing between LP and LSCC in cases of a type V pattern of intraepithelial papillary capillary loop. Although NBI application increased the rate of early cancer detection, LP reduces NBI accuracy. This drawback may lead to misdiagnosis and improper treatment. Our advice is to be careful in cases of type V pattern on NBI and to research LP epithelial and clinical features because it could be a pitfall.

Robotic lateral oropharyngectomy following diagnostic tonsillectomy is oncologically safe in patients with human papillomavirus‐related squamous cell cancer: Long‐term results

Introduction To report the long‐term oncological and functional outcomes of en bloc TORS lateral oropharyngectomy to address the close/involved margin following diagnostic tonsillectomy in HPV‐related SCC of unknown primary. Material and methods A single tertiary center observational cohort over a 4‐year period. Primary outcome measures were disease‐specific survival (DSS), overall survival (OS), and PSS NOD (Performance Status Scale‐Normalcy of Diet) scores. Results TORS specimens did not evidence residual carcinoma in 93% of patients. Of 14 patients, 50% received surgery alone (median follow‐up 57 months; range 46–96), the remainder surgery and adjuvant therapy (median follow‐up of 58 months; range 51–69) with 100% DSS, OS and no deterioration of PSS NOD scores. Conclusions Long‐term oncological outcomes confirm TORS lateral oropharyngectomy alone is an oncologically safe treatment. Due consideration of this approach is warranted to mitigate against the morbidity of adjuvant radiotherapy treatment in this group of patients.

Narrow band imaging for head and neck malignancies: Lessons learned from mistakes

Abstract: The WLE + NBI improved diagnostic accuracy, but not all lesions were ideally evaluated with current defined patterns. An accurate anamnesis is mandatory, because, in some cases, it may be more relevant than the NBI pattern.
