“…Specifically, as regards NBI utility in the follow-up of HNSCC, previous studies reported a sensitivity between 90 and 100%, specificity between 76 and 97%, and accuracy between 86.3% and 100% [8]. Our findings of 100% sensitivity, 98.6% specificity, and 98.8% accuracy are in line with the higher values reported by previous studies.…”

“…Endoscopy under WL was considered "positive" in the case of persistent and demarcated red lesions, white lesions, elevated lesions, and ulcerative lesions. NBI was defined "positive" according to the pattern previously described for the oral cavity [17,18], oropharynx and hypopharynx [5,8,19,20], and larynx [21].…”

“…The utility of NBI has been demonstrated in different scenarios in HNSCC: it allows identification of the primary tumor in the case of neck metastasis of unknown origin [7]; if a tumor is macroscopically visible it better delineates its superficial extension with important implications for guiding the surgical resection [8]. In the case of potentially malignant disorders such as leukoplakia, erythroplakia and oral lichen planus [9] NBI improves the diagnostic accuracy for the early recognition of malignant transformation [10][11][12][13].…”

Purpose Narrow band imaging (NBI) enhances mucosal vasculature and could help in the identification of recurrences. We assessed the effectiveness of NBI with flexible video-endoscope in the early detection of recurrence after treatment of head and neck squamous cell carcinoma, its diagnostic advantage over high-definition white-light (HD WL) endoscopy, also in relation to recurrence site, and the influence of previous radiotherapy (RT) or chemotherapy (CT). Moreover, we investigated the association between index tumor site and the risk of developing recurrence, and the relation between index tumor site and recurrence site. Methods From January 2018 to November 2020, 160 patients previously treated with surgery and/or RT ± CT were evaluated using NBI with flexible video-endoscope. Sensitivity, specificity, positive/negative predictive value, and accuracy were calculated for NBI and HD WL, and compared using the McNemar test. The Fisher exact test was used to compare the other associations investigated. ResultsThe difference between NBI and HD WL sensitivity was statistically significant (p < 0.001). The NBI diagnostic advantage was 62.5%, highest in the hypopharynx (p = 0.05), and was not influenced by previous RT or CT (p = 0.49). Index tumor site statistically related with recurrence site (p < 0.001), but not with the risk of developing recurrence (p = 0.81). Conclusion NBI with flexible video-endoscope could represent a valid option to detect recurrence early during the followup, especially in a difficult-to-visualize site such as the hypopharynx.

“…In NBI, the visualization of microvascular structures is enhanced as the blue to green wavelengths penetrate superficial layers of the mucosa [35]. Typical limitations of NBI, such as blood altering light penetration and a procedural learning curve, do not seem to play a role in the cystoscopy for bladder cancer [36].…”

“…In PDD, there is an ongoing pilot study (NCT03058705) assessing a highly sensitive multi-spectral imaging modality (near infrared fluorescence or NIRF) with the potential to speed up the detection of bladder cancer fluorescence after the infusion of hexaminolevulinate compared to the standard PDD. Both PDD and NBI are also being evaluated for their potential to evaluate surgical margins intraoperatively and thereby improve long-term outcomes for patients with NMIBC [36,47].…”

Despite early detection and regular surveillance of non-muscle invasive bladder cancer (NMIBC), recurrence and progression rates remain exceedingly high for this highly prevalent malignancy. Limited visualization of malignant lesions with standard cystoscopy and associated false-negative biopsy rates have been the driving force for investigating alternative and adjunctive technologies for improved cystoscopy. The aim of our systematic review and meta-analysis was to compare the sensitivity, specificity, and oncologic outcomes of photodynamic diagnosis (PDD) fluorescence, narrow band imaging (NBI), and conventional white light cystoscopy (WLC) in detecting NMIBC. Out of 1,087 studies reviewed, 17 prospective non-randomized and randomized controlled trials met inclusion criteria for the study. We demonstrated that tumor resection with either PDD and NBI exhibited lower recurrence rates and greater diagnostic sensitivity compared to WLC alone. NBI demonstrated superior disease sensitivity and specificity as compared to WLC and an overall greater hierarchical summary receiver operative characteristic. Our findings are consistent with emerging guidelines and underscore the value of integrating these enhanced technologies as a part of the standard care for patients with suspected or confirmed NMIBC.

Adaptive denoising hyperspectral data for visualization enhancement of intraoperative tissue

The vast amount of reflectance information obtained from the hyperspectral imaging devices offers great opportunities for investigating the function and structure of human tissue. However, the captured hyperspectral data often contain various noises due to the intrinsic imperfection of associated electrical and optical imaging components. This work proposed an automatic total variation algorithm to suppress the noises while preserving the details of the spectral and spatial information. The variation of spectral images at neighboring bands was calculated for regulating the total variation of hyperspectral data so that the spectral-dependent noises can be treated differentially across all bands.Experimental results demonstrated that the proposed method could effectively remove the spectral noises, especially near the ends of those extreme bands.The noise suppressed hyperspectral data could then be used for the visualization enhancement on pathophysiological conditions of intraoperative observed anatomies such as the vessels of brain tissues.
