Résumé

Development and validation of a confocal laser endomicroscopy (CLE) classification score for the larynx and pharynx. Thirteen patients (154 video sequences, 9240 images) with laryngeal or pharyngeal SCC were included in this prospective study between October 2020 and February 2021. Each CLE sequence was correlated with the gold standard of histopathological examination. Based on a dataset of 94 video sequences (5640 images), a scoring system was developed. In the remaining 60 sequences (3600 images), the score was validated by four CLE experts and four head and neck surgeons who were not familiar with CLE. Tissue homogeneity, cell size, borders and clusters, capillary loops and the nucleus/cytoplasm ratio were defined as the scoring criteria. Using this score, the CLE experts obtained an accuracy, sensitivity, and specificity of 90.8%, 95.1%, and 86.4%, respectively, and the CLE non-experts of 86.2%, 86.4%, and 86.1%. Interobserver agreement Fleiss' kappa was 0.8 and 0.6, respectively. CLE can be reliably evaluated based on defined and reproducible imaging features, which demonstrate a high diagnostic value. CLE can be easily integrated into the intraoperative setting and generate real-time, in-vivo microscopic images to demarcate malignant changes. Interpretazione sistematica dell’endomicroscopia confocale laser: punteggio endomicroscopico confocale laringeo e faringeo. Sviluppo e validazione di un punteggio di classificazione dell’endomicroscopia laser confocale (CLE) per la laringe ed il faringe. Tredici pazienti (154 sequenze video, 9240 immagini) con SCC laringeo o faringeo sono stati inclusi in questo studio prospettico tra ottobre 2020 e febbraio 2021. Ogni sequenza CLE è stata correlata con il gold standard, ovvero l’esame istopatologico fissato con ematossilina ed eosina (H&E). Sulla base di un set di dati di 94 sequenze video (5640 immagini), è stato sviluppato un sistema di punteggio. Nelle restanti 60 sequenze (3600 immagini), il punteggio è stato convalidato da quattro esperti di CLE e quattro chirurghi della testa e del collo che non avevano familiarità con la CLE. L’omogeneità dei tessuti, le dimensioni delle cellule, i bordi e i cluster, i loop capillari e il rapporto nucleo/citoplasma sono stati definiti come criteri di punteggio. Utilizzando questo punteggio, gli esperti di CLE hanno ottenuto un’accuratezza, una sensibilità e una specificità del 90,8%, 95,1% e 86,4%, rispettivamente, e i non esperti di CLE dell’86,2%, 86,4% e 86,1%. L’accordo tra osservatori Fleiss’kappa era rispettivamente di 0,8 e 0,6. CLE può essere valutato in modo affidabile sulla base di caratteristiche di imaging definite e riproducibili, che dimostrano un alto valore diagnostico. CLE può essere facilmente integrato nell’impostazione intraoperatoria e generare immagini microscopiche in tempo reale e in vivo per delimitare i cambiamenti maligni.
