“…There were 398 benign lesions and 188 malignant lesions assessed in total. Four studies classified IPCL changes according the Ni 2011 classification alone 19,25‐27 . Two studies classified IPCL changes according to both Ni 2011 and ELS classification system 18,20 .…”

“…However, various authors have demonstrated that NBI is still able to differentiate benign and malignant laryngeal leukoplakia with high accuracy by observing IPCL changes at the peripheries of leukoplakia 18 . Rzepakowska et al assessed 91 laryngeal lesions with leukoplakia and reported high sensitivities and specificities of 100% and 97.4%, respectively 19 . Huang et al 20 also demonstrated that NBI can differentiate between benign and malignant laryngeal leukoplakia; however, the accuracy reported was much lower.…”

Utility of narrowband imaging in the diagnosis of laryngeal leukoplakia: Systematic review and meta‐analysis

et al. 2020

This systematic review and meta-analysis evaluates the validity of narrowband imaging (NBI) in differentiating between low-risk leukoplakia and high-risk leukoplakia. Medline, EMBASE, Scopus, Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effects were searched. Studies evaluating the diagnostic accuracy of NBI in the assessment of laryngeal leukoplakia were included. Pooled sensitivity, specificity and diagnostic odds ratio were calculated. Seven studies met the inclusion criteria assessing a total of 586 lesions with laryngeal leukoplakia. In differentiating between low-risk and high-risk leukoplakia, NBI had a pooled sensitivity and specificity of 85.4% (95% CI [76-99.9]) and 94.9% (95% CI [91.1-97.2]) respectively. Pooled diagnostic odds ratio was 99.2 (95% CI [38.28-257.18]). NBI is a useful imaging modality in differentiating between low-risk leukoplakia and high-risk laryngeal leukoplakia. The high sensitivity, specificity and diagnostic odds ratio make NBI a useful tool in the workup of laryngeal leukoplakia.

“…These abnormally dilated microvessels correspond to mucosal congestion and vascular stippling in white light imaging; hence, the information provided by narrow-band imaging can counter the deficiency of white light imaging laryngoscopy when classifying vocal fold leukoplakia. In addition, with this technology, a biopsy can be avoided when predicting the pathological nature of some lesions, 15 thereby avoiding unnecessary trauma and playing an important role in the functional protection of vocal folds. Five intra-epithelial papillary capillary loop typing criteria for laryngeal lesions were first summarised by Ni et al according to the characteristic dynamic changes of intra-epithelial papillary capillary loop morphology on the mucosal surface of laryngeal lesions during the development process from a normal state to dysplasia and cancer.…”

Objective To investigate the value of narrow-band imaging training for differentiating between benign and malignant vocal fold leukoplakia. Method Thirty cases of vocal fold leukoplakia were selected. Results Narrow-band imaging endoscopy training had a significant positive effect on the specificity of the differential diagnosis of vocal fold leukoplakia. In addition, the consistency of diagnostic typing of vocal fold leukoplakia by narrow-band imaging improved to ‘moderate agreement’ following the combination of types I and II and the combination of types IV, V and VI in the typing of vocal fold leukoplakia. Conclusion The narrow-band imaging training course may improve the ability of laryngologists to diagnose vocal fold leukoplakia. The new endoscopic diagnostic classification by narrow-band imaging needs to be further simplified to facilitate clinical application.

“…Given that the mainstay of treatment for HPT remains surgical, with a number of specific techniques described and variably used, the results of this study remain applicable across a broad range of practices. 15,16 One final limitation was that our study was not randomized or controlled.…”

Baseline intraoperative intact parathyroid hormone levels in parathyroid surgery

et al. 2018

Background We sought to evaluate the relationship between the preoperative core‐laboratory parathyroid hormone (CL‐PTH) level and the baseline intraoperative PTH (IOPTH) level and assess the impact of any differences on clinical decision making in consecutive surgical patients with primary hyperparathyroidism undergoing parathyroidectomy. Methods The CL‐PTH and baseline IOPTH levels were compared. The influence of relying on either the CL‐PTH or baseline PTH levels for intraoperative decision making was determined. Results Data were available for 316 patients. Baseline IOPTH measurements were usually higher than the CL‐PTH (247 patients; 78.2%) measurements, with a mean difference of 68.2 pg/mL (P < .001). Using the CL‐PTH as a surrogate for the baseline parathyroid hormone (PTH) would have prolonged the operation in 23 patients (7.3%). Conclusion Baseline point‐of‐care IOPTH levels were higher than the preoperative CL‐PTH levels in >75% of patients undergoing parathyroidectomy. Using the CL‐PTH in lieu of an IOPTH baseline value would prolong the operation in some patients.

Narrow band imaging for risk stratification of glottic cancer within leukoplakia

Abstract: The noninvasive procedure of an NBI endoscopy may be recommended as an accurate method in predicting the risk of malignant transformation within the vocal fold leukoplakia and, therefore, would be useful in the clinic for planning the patient's therapy.
