Salvage carbon dioxide transoral laser microsurgery for laryngeal cancer after (chemo)radiotherapy: a European Laryngological Society consensus statement

Purpose To provide expert opinion and consensus on salvage carbon dioxide transoral laser microsurgery (CO2 TOLMS) for recurrent laryngeal squamous cell carcinoma (LSCC) after (chemo)radiotherapy [(C)RT].Methods Expert members of the European Laryngological Society (ELS) Cancer and Dysplasia Committee were selected to create a dedicated panel on salvage CO2 TOLMS for LSCC. A series of statements regarding the critical aspects of decision-making were drafted, circulated, and modified or excluded in accordance with the Delphi process.Results The expert panel reached full consensus on 19 statements through a total of three sequential evaluation rounds. These statements were focused on different aspects of salvage CO2 TOLMS, with particular attention on preoperative diagnostic work-up, treatment indications, postoperative management, complications, functional outcomes, and follow-up.Conclusion Management of recurrent LSCC after (C)RT is challenging and is based on the need to find a balance between oncologic and functional outcomes. Salvage CO2 TOLMS is a minimally invasive approach that can be applied to selected patients with strict and careful indications. Herein, a series of statements based on an ELS expert consensus aimed at guiding the main aspects of CO2 TOLMS for LSCC in the salvage setting is presented.Otorhinolaryngolog

Involvement of the Anterior Commissure in Early Glottic Cancer (Tis-T2): A Review of the Literature

Background: The impact of the anterior commissure (AC) involvement on prognosis in laryngeal cancer remains a topic of discussion with inconsistent results in the literature. This review examines AC involvement as a prognostic factor in patients with early glottic cancer (Tis-T2) treated with radiotherapy or transoral laser microsurgery (TLM). Methods: A systematic literature search was performed. Due to the heterogeneity of the data, no meta-analysis was implemented. Weighted averages were calculated if the appropriate data were extractable. Results: Thirty-four studies on radiotherapy and 23 on TLM fit the inclusion criteria. The majority of studies for both radiotherapy (67.7%) and TLM (75.0%) did not report a significant impact on oncological outcomes. Weighted averages were slightly lower in patients with AC involvement. The two studies that applied a more detailed classification showed a significant impact on the amount of AC involvement. Conclusions: Binary variables (yes/no) for AC involvement lead to inconsistent results. Studies that use more detailed classifications of the AC show that there is a significant impact on the outcome. To further elucidate the role of the AC, detailed stratification of tumors involving the AC need to be investigated in further studies for both treatment modalities.Otorhinolaryngolog

Adductor spasmodic dysphonia: Botulinum toxin a injections or laser thyroarytenoid myoneurectomy? A comparison from the patient perspective

Objectives/Hypothesis The current gold standard of therapy for adductor spasmodic dysphonia (AdSD) is injection of botulinum toxin A (BTX) in the adductor musculature. A surgical procedure could potentially offer more stable and long-lasting voice quality. In this study, we report the long-term results of endoscopic laser thyroarytenoid (TA) myoneurectomy versus BTX treatment in the same patients with AdSD.Study Design Retrospective case series.Methods Between July 2013 and September 2016, a total of 22 patients with AdSD were included. Voice outcomes were measured using the Voice Handicap Index and a Likert-scale patient-reported voice questionnaire. Data were obtained for each patient at four time points: preoperatively with and without BTX and twice postoperatively at 3 months (short term) and 12 months (long term).Results No statistically significant differences were found between voice outcome after BTX injection and the short- and long-term postoperative voice outcomes for the group as a whole. During postoperative follow-up, 10 of the 22 patients (45%) needed a second procedure after an average of 18 months (interquartile range, 13-22 months) due to recurrence of their original voice problem.Conclusions The TA myoneurectomy showed encouraging results, comparable to BTX after follow-up of 12 months for the group as a whole. However, after good results initially, voice deterioration was seen in 45% of the patients who all underwent a second procedure. These preliminary results provide important insights into the value of TA myoneurectomy as a potential definite treatment for a select group of patients with AdSD. Further research might explore long-term results after revision surgery.Level of Evidence 4Laryngoscope, 130:741-746, 2020Otorhinolaryngolog

Evaluation of surgical margin status in patients with early glottic cancer (Tis-T2) treated with transoral CO2 laser microsurgery, on local control

Purpose To assess the impact of surgical margins status on local control in patients with primary early glottic (Tis-T2) squamous cell carcinoma after treatment with transoral CO2 laser microsurgery (TLM) and to assess the significance of additional wound bed biopsies.Methods Patients with Tis-T2 tumours treated with TLM type I-III resections according to the European Laryngological Society classification between 2009 and 2013 were included in retrospective analysis. Recurrence rate was determined in patients with free versus non-free specimen margins and wound biopsies. Five-year survival rates were determined using the Kaplan-Meier method. Prognostic impact of pT-category, resection margin status, tumour differentiation, wound bed biopsy status, and number of biopsies on local control (LC) were tested with the log-rank test.Results Eighty-four patients were included in the analysis. Positive margins were seen in 68 patients (81.0%). Margin status after TLM did not significantly influence LC (p = 0.489), however, additional wound bed biopsies were significantly associated with lower LC (p = 0.009). Five-year LC, disease-specific survival, overall survival and laryngeal preservation were 78.6, 78.0, 98.6 and 100%, respectively.Conclusions Additional wound bed biopsies can help predict local recurrence in patients treated with TLM for early glottic carcinoma. We propose that there is enough evidence to support a wait-and-see policy in patients with positive specimen margins and negative wound bed biopsies. For patients with positive wound bed biopsies, further treatment is warranted.Otorhinolaryngolog

Outcomes of CO2 laser-assisted posterior cordectomy in bilateral vocal cord paralysis in 132 cases

The purpose of the study was to assess the role of laser-assisted posterior cordectomy in the management of patients with bilateral vocal cord paralysis. We aimed an analysis of 132 consecutive patients treated by CO2 laser posterior cordectomy, aged 38-91, 31% tracheotomized on admission. Cordectomy was performed under microlaryngoscopy using CO2 laser (Lumenis AcuPulse 40 CO2 laser, wavelength 10.6 mu m, Lumenis Ltd., Yokneam, Israel). We looked at the number of laser glottic procedures necessary to achieve decannulation in tracheotomized patients and to achieve respiratory comfort in non-tracheotomized subjects and we evaluated the two groups for differences in patient characteristics. In tracheotomized patients, we also assessed factors affecting the success of decannulation and we evaluated the impact of tracheotomy on patients' lives. Decannulation was performed in 63% of tracheotomized patients. In terms of the number of procedures, 54% (14), 19% (5), and 27% (7) tracheotomized vs. 74% (61), 24% (20), and 2% (2) non-tracheotomized subjects underwent one, two, or three procedures, respectively. In the group of tracheotomized patients who were successfully decannulated, the number of multiple laser-assisted procedures was significantly higher than in the group of non-tracheotomized subjects with respiratory comfort after treatment (p = 0.04). Advanced age (> 66 years), comorbidities (diabetes, gastroesophageal reflux disease (GERD)), multiple thyroid surgeries, and tracheotomy below the cricoid cartilage were found to decrease the likelihood of successful decannulation. Posterior cordectomy is a simple method allowing for airway improvement and decannulation in patients with bilateral vocal cord paralysis. It is less effective in tracheotomized subjects with diabetes or GERD, older than 66 years old, after two or more thyroidectomies.Otorhinolaryngolog
