Abstract

Background: Spectra-A(S) is a part of a novel endoscopic imaging technique based on color tone shift algorithm to increase contrast based mainly on the green (540 nm) and blue (415 nm) light spectral signals designed for the visualization of abnormal microvasculature on the mucosal surface such as intraepithelial papillary capillary loop pattern (IPCL). Transoral laser microlaryngeal cordectomy (TLMC) surgery is performed using a laser with the microscope and the histopathology report is the gold standard in deciding the free margins. Aim: To assess the accuracy of the combined findings of S light, subepithelial infiltration (I), and palpation (P) of the vocal fold lesion in deciding the margins in TLMC for early glottic cancer, considering the final histopathology report as the gold standard. Results: Out of a total of 35 study patients, the results of specimen identification protocol (SIP) in deciding free margins were in concordance with the histopathological report (HPR) in 26 patients. Since using a combination of SIP is less resource intensive than frozen section (FS), it may be useful in places where intraoperative FS is not available. Conclusion: The accuracy of the combined findings of SIP in deciding the margins in TLMC for early glottic cancer was 74%. The gold standard was taken as the final histopathology report.
