Purpose: We assessed the treatment outcome and the benefits of routine follow-up visits in T1 glottic laryngeal squamous cell carcinoma (LSCC). Methods: Medical records of patients diagnosed with stage T1 glottic LSCC (N = 303) in five Finnish university hospitals between 2003 and 2015 were reviewed. Moreover, data from the Finnish Cancer Registry and the Population Register Center were collected. Results: Of all 38 recurrences, 26 (68%) were detected during a routine follow-up visit, and over half (21 of 38, 55%) presented without new symptoms. Primary treatment method (surgery vs. radiotherapy) was not connected with 5-year disease-specific survival (DSS) or laryngeal preservation rate. Conclusion: The majority of recurrences were detected on a routine follow-up visit, and local recurrences often presented without new symptoms. Routine post-treatment follow-up of T1 glottic LSCC seems beneficial. Trial registration: Trial registration number and date of registration HUS/356/2017 11.12.2017.

BackgroundThe surgical treatment of glottic, or vocal cord, cancer has seen considerable progression over the past several decades. Specifically, there has been a stark transition from open partial laryngectomy surgery to endoscopic laser microsurgical techniques which have been inspired in large part by two landmark studies: Professor Wolfgang Steiner's original case series describing transoral laser microsurgery for glottic cancer (1993) and the European Laryngological Society's (ELS) classification scheme (2000). We performed a comprehensive review of published literature to characterize the pattern of this novel modality as compared with two landmark studies over the past four decades.MethodsAn English literature search was conducted on PubMed for available original investigations on surgical treatment of glottic laryngeal cancer published over the past 40 years. Our Boolean criteria included the following terms: cancer, glottic, laryngeal, surgery, endoscopic, and laser. The publication rates were calculated as annual compound growth as well as corrected growth rates as defined by the Fisher equation for inflation effects.ResultsOur review identified 13,372 studies covering larynx cancer and 3,557 studies covering glottic cancer original studies. Among these, we analyzed the compound annual growth rates and correct growth rates for three distinct publication periods or epochs, prior to 1993, 1993-1999, and 2000-2017. For all but two of the search term groups covering both glottic cancer as well as larynx cancer, there was a substantial growth improvement in the time period following the ELS classification scheme as compared with the growth rate of the time period following Steiner's case series.ConclusionThe progress toward minimally invasive treatment of glottic cancer has progressed steadily over the past several decades. Analysis of publication show increased growth during the time period following the ELS classification scheme over the time period following

BackgroundAlthough intensity-modulated radiotherapy (IMRT) is a standard of care for many head and neck cancers, its use for carotid-sparing (CS) therapy in early-stage laryngeal carcinoma is controversial.Methods330 consecutive patients with early-stage laryngeal carcinoma were treated from 1/1989 to 5/2011, including 282 conventional radiotherapy (CRT) and 48 CS-IMRT patients. The median follow-up was 43 (CS-IMRT) and 66 (CRT) months.ResultsThere was no difference in local failure rates comparing patients undergoing CS-IMRT with CRT, with 3-year local control rates of 88% vs. 89%, respectively (p=0.938). Using a 1cm circumferential margin, the average dose to the left and right carotid arteries was 48.3 and 47.9 Gy, respectively. 88% of locoregional recurrences involved the ipsilateral true vocal cord, including all local recurrences in the IMRT group.ConclusionsThese results warrant further prospective evaluation of CS-IMRT for early-stage glottic larynx cancer.

Medical terminology frequently mistakes the instrument for the surgical procedure: endoscopic excision of laryngeal cancers existed long before laser came into use. Lasing obeys the same rules as those of suspension laryngoscopy: if adequate laryngeal exposure is not attained, then the procedure is at risk of being incomplete and of providing few satisfactory results. Because a certain degree of literary anarchy exists in terms of definitions for the different cordectomy types, the Nomenclature Committee of the European Laryngological Society has proposed a classification. This categorization is a synthesis and a compromise between members of the Society who had developed and used, for several years, a personal classification. The proposed classification has two aims: to better understand each surgeon's technique in function of the tumoral extent; and to compare more rigorously the postoperative results. This classification includes the following procedures: Subepithelial cordectomy or decortication (Type I); Subligamentous cordectomy (Type II); Transmuscular cordectomy (Type III); Total or complete cordectomy (Type IV); Extended cordectomy encompassing the contralateral vocal fold (Type Va); encompassing the arytenoid (Type Vb); encompassing the ventricular fold (Type Vc); encompassing the subglottis (1 cm) (Type Vd).
