Abstract
PURPOSE Laser cordectomy is a widely accepted treatment modality for selected cases of early glottic cancers, but its role as a salvage treatment remains unclear. We aimed to investigate the oncological outcomes and failure patterns of salvage cordectomy. MATERIALS AND METHODS This was a retrospective cohort study of patients who underwent cordectomy for early glottic cancer between 2013 and 2022 at a tertiary referral center. The main outcome measures were overall survival, larynx-preservation rate, tracheostomy dependency rate, and disease-free survival. RESULTS A total of 142 patients (mean age: 63 years, interquartile range [IQR]: 45-72, 123[86.9 %] males) were analyzed. There were 38 (26.8 %) recurrences after a mean of 22 months (IQR: 17-26). Among them, 25 (17.6 %) underwent salvage cordectomy, while 13 (9.1 %) received other salvage treatments (11[7.7 %] (chemo)radiotherapy and 2[1.4 %] total laryngectomy). In comparison to the other salvage treatments, salvage cordectomy demonstrated lower tracheostomy rates (0 vs. 31 %, p = 0.05), comparable 5-year disease-free survival (62 % vs. 54 %, p = 0.4), higher 5-year larynx preservation rate (92 % vs. 54 %, p = 0.02), and improved 5-year overall survival rate (84 % vs. 62 %, p = 0.01). Factors associated with salvage cordectomy failure were age >60 years (odds ratio [OR]: 1.3, 95 % confidence interval [CI]: 1.15-1.53), smoking continuation (OR: 3.73, 95 % CI: 3.5-4.4), heavy smoking (OR: 1.24, 95 % CI:1.07-2.15), and pT1b + (OR: 2.26, 95 % CI: 2.1-2.9). CONCLUSIONS Salvage cordectomy offers favorable larynx preservation rates and oncological outcomes for recurrent disease amenable to conservative surgery. Smoking, advanced age, and advanced tumor stages are associated with salvage cordectomy failure.

J Voice 2023:S0892-1997(23)00286-2. [PMID: 37805300 DOI: 10.1016/j.jvoice.2023.09.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 09/12/2023] [Indexed: 10/09/2023]
Abstract
The 445-nm blue laser combines the features of photocoagulative vascular lasers and cutting lasers in one device. The purpose of the present study was to evaluate the safety and efficacy of the 445-nm blue laser for the treatment of benign laryngeal pathologies, other than vascular lesions. Outcomes were compared to those when already-established therapies were used. METHODS Adult voice center patients who underwent surgical intervention for vocal fold (VF) mass, VF scar, laryngeal stenosis, laryngeal web, or Reinke's edema were included in this retrospective study. Outcomes were compared to those achieved when traditional treatment modalities were used, including cold steel, CO2 laser, potassium-titanyl-phosphate (KTP) laser, and coblator. Strobovideolaryngoscopy footage was evaluated using a previously described model at four time points: postoperative visit #1: 1-14 days, postoperative visit #2: 30-60 days, postoperative visit #3: 61-365 days, postoperative visit #4: >365 days. RESULTS Eighty cases using the blue laser and 153 controls (n = 78 cold steel, n = 51 KTP laser, n = 22 CO2 laser, n = 2 coblator) were included in this study. Procedures performed using blue laser included VF mass excision (n = 45), VF scar reduction (n = 16), laryngeal stenosis resection/repair (n = 25), laryngeal web excision (n = 7), and reduction of Reinke's edema (n = 1). On postoperative strobovideolaryngoscopy examination, the surgical objective score did not differ significantly between the blue laser cohort and all controls at any postoperative visit. VF edema did not differ significantly between the blue laser cohort and all controls at any postoperative visit. VF hemorrhage scores were significantly lower in the blue laser cohort compared to all controls at the first postoperative visit, but hemorrhage had resolved almost entirely by the second postoperative visit in all groups. Postoperative VF stiffness was worse in the blue laser group at the third postoperative visit compared to controls, but both groups had improved to similar levels by the fourth postoperative visit. The rate of lesion recurrence (24.29% versus 17.19%) did not differ significantly between the blue laser cohort and controls on multivariate analysis (Odds ratio [OR] = 1.081 [0.461-2.536]). The complication rate (12.50% versus 10.46%) did not differ significantly between the blue laser cohort and all controls on multivariate analysis (OR = 0.992 [0.375-2.624]). The blue laser was associated with a lower rate of revision surgery (30.00% versus 34.64%) on multivariate analysis (OR = 0.380 [0.168-0.859]). CONCLUSION The 445-nm blue laser is safe and effective for the management of benign laryngeal lesions. It has efficacy and safety similar to those of traditional treatment modalities (including cold steel, CO2 laser, and KTP laser). Use of the blue laser may lead to lower rates of early postoperative hemorrhage and revision surgery. No adverse effects attributed directly to the use of the blue laser were observed in this study. Further research is encouraged to confirm or refute these findings.

Abstract
The incidence of all head and neck malignancies is rising worldwide, with carcinoma of the larynx constituting approximately 1% of all cancers. Early glottic cancer responds quite favorably to surgical intervention due to its early presentation, coupled with the low rate of regional and distant metastases. This article focuses on various approaches to the surgical treatment of early glottic cancer. Details include the clinical and radiological evaluation of laryngeal cancer, the goals of treatment, current surgical options for early disease, approach to surgical resection margins and management of nodal disease, and complications associated with each treatment modality.

Abstract
OBJECTIVES To evaluate the safety and clinical effectiveness of transoral laser microsurgery (TLM) with potassium-titanyl-phosphate (KTP) laser ablation for glottic neoplasms. DATA SOURCE MEDLINE via PubMed, SCOPUS, Web of Science, and Cochrane Library. REVIEW METHODS A systematic review and meta-analysis of studies assessing the safety and efficacy of KTP laser therapy in patients with early-stage glottic neoplasms. RESULTS Eight studies were included. After an average follow-up of 3.3 years, the overall survival and disease-free survival for patients who underwent KTP were 90.7% (95% CI 85%-96.5%) and 98.5% (95% CI 97.3%-99.8%), respectively. In the single-arm meta-analysis, the pooled estimate of recurrence was 7.7% (95% CI 3.4%-12%). The overall voice handicap index (VHI) estimate attributed to KTP in the single-arm meta-analysis was 6.76 (95% CI [3.05, 10.48]) and 5.21 (95% CI [2.86, 7.56]) within 6 months and after a one-year follow-up, respectively. CONCLUSION KTP laser ablation is a safe and effective method for treating patients with early glottic neoplasms. Laryngoscope, 2023.

J Voice 2022:S0892-1997(22)00140-0. [PMID: 35781175 DOI: 10.1016/j.jvoice.2022.05.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 05/11/2022] [Indexed: 10/17/2022]
Abstract
Photoangiolytic lasers such as the 532-nm potassium-titanyl-phosphate (KTP) and the novel 445-nm blue laser (introduced into the United States in 2020) are absorbed selectively by hemoglobin, permitting targeted ablation of vascular structures such as vascular malformations of the vocal fold (VF). Previously, we reported the high rate of success of KTP laser photocoagulation for VF vascular lesions. Compared with other photoangiolytic lasers, blue laser has the highest absorption in hemoglobin, and therefore it can be operated at lower power densities to minimize thermal injury to adjacent tissue. OBJECTIVE The purpose of this study was to determine the efficacy and safety of blue laser for treatment of VF vascular lesions using low power densities, and to compare outcomes of blue laser with those of KTP laser. METHODS Adult voice patients who underwent blue laser treatment of VF vascular lesions in the operating room at the lowest power densities that appeared clinically to cause the effect desired were included in this retrospective study. Baseline lesion characteristics and postoperative outcomes were assessed with a model that we had described previously. Postoperative outcomes were compared to those of previously reported KTP laser. RESULTS Thirty-one subjects (54 VFs treated) underwent blue laser vaporization of VF vascular lesions (average age was 40.63 ± 17.51). Data were compared to those of 66 subjects (100 VFs) who had undergone KTP laser vaporization of VF vascular lesions. There were no significant differences in subject demographics, past medical or surgical history, or preoperative location or severity of vascular lesions. Surgical success for blue laser at the low power densities used was 3.74 ± 0.50, 3.55 ± 0.94, 3.90 ± 0.94, and 3.70 ± 1.11 (out of 5) at postoperative visits 1-4, respectively. Surgical objective score was significantly greater following KTP laser at every postoperative visit. Treatment with KTP laser resulted in significantly greater generalized postoperative edema, and blue laser resulted in significantly greater localized edema at postoperative visits one and two. At visit three and four, there are no significant differences. VF stiffness following blue laser was 2.41 ± 0.67, 1.91 ± 0.69, 1.33 ± 0.47, and 1.10 ± 0.18 (out of 4) at postoperative visits 1-4, respectively. Postoperative VF stiffness did not differ significantly from KTP laser. Postoperative hemorrhage severity after blue laser was 1.79 ± 0.54, 1.59 ± 0.48, 1.15 ± 0.25, and 1.14 ± 0.26 (out of 4) at postoperative visits 1-4, respectively. Blue laser resulted in significantly less VF hemorrhage than KTP laser at the first (1.79 ± 0.54 versus 2.26 ± 0.83) and second (1.59 ± 0.48 versus 1.98 ± 0.72) postoperative visits. Vascular lesions treated with low-power-density blue laser were significantly more likely to recur than those treated with KTP laser (40.74% versus 10.00%). New vascular malformations were significantly more likely to form after blue laser than KTP (24.07% versus 6.00%). Subjects treated with low-power-density blue laser were significantly more likely to undergo repeat surgery than those treated with KTP (31.48% versus 14.00%). Significant predictors for the need for repeat blue laser included lesion recurrence, a lower surgical objective score at the third or fourth postoperative visit and a higher baseline lesion severity grade. CONCLUSION Blue laser is an effective tool for the surgical management of VF vascular lesions. Although overall surgical success ratings were inferior to KTP laser at the power densities used, the severity of postoperative edema and VF hemorrhage were significantly less with blue laser. Re-evaluation of blue laser using higher power densities is in progress.

Laryngectomy-free survival after salvage partial laryngectomy: a systematic review and meta-analysis. Eur Arch Otorhinolaryngol 2022; 279:3021-3027. [PMID: 35039895 DOI: 10.1007/s00405-022-07257-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Accepted: 01/03/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE Radiotherapy (RT) is widely used for early glottic cancer. Patients failing this treatment are referred to surgical management of their disease. Salvage partial laryngectomy (SPL) has the advantage of preserving laryngeal function with total laryngectomy (TL) remaining as a last resort. The purpose of this study was to determine the efficacy of SPL in preventing total laryngectomy, following failed RT, for early glottic cancer. METHODS A meta-analysis of all published English literature was performed. All publications that included patients undergoing SPL were reviewed according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) reporting guidelines. The search strategy identified 154 relevant articles. A total of 15 retrospective studies that included 323 suitable patients were subsequently analyzed in this meta-analysis. The main outcome measure was the rate of laryngectomy-free survival (LFS) following SPL. The indications for salvage TL (i.e., disease recurrence and poorly functional larynxes) as well as subgroup analyses for open and trans-oral SPLs were also calculated. RESULTS The overall rate of LFS following SPL was 81.2% (fixed effects model range: 75.7-86.8%). Salvage TL following SPL were performed in 96.8% due to disease recurrence and in 3.2% to poorly functional larynxes. A subgroup analysis showed a 90.4% LFS after open SPL and 78.6% following trans-oral SPL. CONCLUSION A high rate of successful salvage partial laryngectomies, regardless of surgical technique, is to be anticipated in well-selected patients after RT failure.

Abstract
Background Local control rate (LCR) of early glottic cancer is high after radiation therapy or transoral laser microsurgery (TLM). The aim of this study was to investigate functional voice outcome after TLM using a microvessel‐ablative potassium‐titanyl‐phosphate (KTP) laser in comparison with a gold standard cutting CO2 laser. Methods The primary end point of this prospective, randomized, single‐blinded, clinical phase II study with control group was voice outcome during a follow‐up of 6 months assayed by Voice Handicap Index (VHI‐30)‐questionnaires in patients with unilateral high‐grade dysplasia, carcinoma in situ or early glottic cancer undergoing TLM‐KTP (n = 8) or TLM‐CO2 (n = 12). The secondary end point was LCR. Results Starting from the 9‐week‐follow‐up visit, TLM‐KTP yielded significantly reduced VHI scores compared to TLM‐CO2. No relapse occurred after TLM‐KTP in contrast to one recurrence after TLM‐CO2 within 6 months. Conclusion Multicenter phase II or III studies on voice outcome or local control rate after TLM‐KTP in early glottic cancer are warranted enrolling larger patient cohorts.

Abstract
Background: Since the renowned opera maestro Manuel Garcia presented “Observations on the Human Voice” using mirror laryngoscopy in 1855, there has been an inextricable link between performing vocalists and laryngologists. Today, specialized laryngeal surgeons continue the tradition of integrating medical and surgical management of performers with those skilled in vocal arts, voice science, and voice therapy. With advances in surgical instrumentation and techniques, increasing opportunities have evolved to surgically restore lost performing voices. However, it is especially challenging because of a range of factors, including the need for optimal technical precision, management of expectations, complexity of informed consent, public visibility of these patients, and the economics related to the success and failure of surgery. A number of these key issues apply to phonomicrosurgical procedures in nonsingers as well. Consequently, reviewing the art and craft of phonomicrosurgery in elite performers provides valuable insights into the optimal management of any patient. Methods: A retrospective review was done of microlaryngeal procedures for the past 20 years, and 18 elite performers were identified who were Grammy Award winners. Microsurgical methods for different lesions are illustrated. Composite analyses of the group along with their associated pathology was done to provide insights into key issues. Results: The 18 patients in this cohort have won 80 Grammy Awards, which were garnered from 242 nominations. All 18 had substantial deterioration in voice quality and could retain more than 1 pathology. Significant loss of superficial lamina propria (SLP) pliability was present in 15 of 18, varices and/or ectasias leading to vocal hemorrhage in 6, vocal polyps in 9, fibrovascular nodules in 6, arytenoid granuloma in 1, sulcus from prior microlaryngeal surgery leading to vocal fold SLP scarring in 4, sulcus from long-term phonotrauma leading to vocal fold SLP scarring in 4, benign cyst in 1, precancerous dysplasia in 2, and invasive carcinoma in 2. Subsequent to phonomicrosurgery, all reported improvement in their performance. Conclusions: Laryngologists and laryngeal surgeons have shouldered a burden of responsibility for elite performing vocalists since the origin of our specialty. Most lesions and diagnoses that are encountered result from phonotrauma. Optimizing singers’ care provides surgeons with extremely complex technical, emotional, social, and financial challenges. Focused analysis of managing elite performing vocalists effectively integrates a range of essential issues, which provide key insights to assist clinicians treating nonperforming patients requiring phonomicrosurgery.

Abstract
Objectives: The aim of this study was to assess the outcome of treating glottic dysplasia and early squamous cell carcinoma (SCC) with potassium titanyl phosphate (KTP) photoangiolytic laser ablation. Methods: Patient demographics, comorbidities, and tumor characteristics were recorded. Perceptual, patient-reported, and objective voice outcomes were assessed. Use of treatment modalities in addition to the KTP laser, development of locoregional or metastatic SCC, and overall survival were recorded. Results: There were 23 patients with glottic dysplasia and 18 patients with glottic SCC. Mean age at treatment was 69 years. Most patients (95%) were male. Posttreatment fundamental frequency fell from 132 ± 35 to 116 ± 24 Hz ( P = .03). Overall, 61% of patients achieved a normal voice. There was a learning-curve, and most treatment failures occurred in the first half of the series. Five-year KTP-only disease-control rates were 87.1% and 53.5% for dysplasia and malignancy, respectively. Five-year overall survival was 56%, with no laryngectomies or deaths due to SCC. Conclusions: Ablating dysplasia and early glottic cancer using a KTP laser is a viable treatment option. It has a learning curve and a failure rate but, in this series, no ultimate loss of oncologic control. Its introduction into clinical practice should be managed carefully in the context of multidisciplinary cancer care. Level of Evidence: 4.

Abstract
Objective After radiation failure for early T-stage larynx cancer, national guidelines recommend salvage surgery. Total laryngectomy and conservation laryngeal surgery with an open or endoscopic approach are both used. Beyond single-institution studies, there is a lack of evidence concerning the outcomes of these procedures. We aim to study whether treatment with conservation laryngeal surgery is associated with poorer outcomes than treatment with total laryngectomy as salvage surgery after radiation failure for T1/T2 larynx cancers. Study Design A retrospective study was conducted of adult squamous cell larynx cancer cases in the National Cancer Database diagnosed from 2004 to 2012. Setting Commission on Cancer cancer programs in the United States. Methods Demographic, facility, tumor, and survival variables were included in the analyses. Multivariate survival regressions as well as univariate Kaplan-Meier analyses were conducted. Results Slightly more than 7% of patients receiving radiotherapy for T1/T2 larynx cancers later received salvage surgery. Salvage with partial laryngectomy was not associated with diminished survival as compared with total laryngectomy. However, positive surgical margins were associated with worse outcomes (hazard ratio, 1.782; P = .001), and a larger percentage of patients receiving partial laryngectomy had positive margins than those receiving total laryngectomy. Facility characteristics were not associated with differences in salvage surgery type or outcomes. Conclusion In recognition of the inherent selection bias, patients who experienced recurrences after radiation for T1/T2 larynx cancer and underwent conservation salvage laryngeal surgery demonstrated clinical outcomes similar to those of patients undergoing salvage total laryngectomy. Increased rates of positive surgical margins were observed among patients undergoing salvage conservation surgery.

Guidelines for the Surgical Management of Laryngeal Cancer: Korean Society of Thyroid-Head and Neck Surgery. Clin Exp Otorhinolaryngol 2017; 10:1-43. [PMID: 28043099 PMCID: PMC5327593 DOI: 10.21053/ceo.2016.01389] [Citation(s) in RCA: 39] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2016] [Accepted: 10/24/2016] [Indexed: 01/08/2023] Open
Abstract
Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to develop clinical practice guidelines for the surgical treatment of laryngeal cancer. This Task Force conducted a systematic search of the EMBASE, MEDLINE, Cochrane Library, and KoreaMed databases to identify relevant articles, using search terms selected according to the key questions. Evidence-based recommendations were then created on the basis of these articles. An external expert review and Delphi questionnaire were applied to reach consensus regarding the recommendations. The resulting guidelines focus on the surgical treatment of laryngeal cancer with the assumption that surgery is the selected treatment modality after a multidisciplinary discussion in any context. These guidelines do not, therefore, address non-surgical treatment such as radiation therapy or chemotherapy. The committee developed 62 evidence-based recommendations in 32 categories intended to assist clinicians during management of patients with laryngeal cancer and patients with laryngeal cancer, and counselors and health policy-makers.

Abstract
Transoral and transcervical surgery to treat glottic cancer has advanced substantially over the past decade. There have been considerable innovations that enhance vocal function for early disease and airway function for advanced disease. The fiber-based angiolytic 532 nm potassium titanyl phosphate laser has provided a new foundational strategy to maintain high cure rates with enhanced vocal outcomes for the treatment of early glottic disease. For advanced glottic cancer, transplanting cryopreserved aortic homograft to reconstruct wide-field laryngotracheal airway defects can provide an adequate airway caliber such that a long-term tracheotomy can frequently be avoided.

Oncologic Efficacy of Angiolytic KTP Laser Treatment of Early Glottic Cancer. Ann Otol Rhinol Laryngol 2014; 123:840-6. [DOI: 10.1177/0003489414538936] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/15/2022]
Abstract
Objective: Angiolytic laser removal of early glottic cancer with ultra-narrow margins was reported in a pilot study 5 years ago as an innovative surgical treatment strategy to better preserve vocal function. Subsequently, in a cohort of > 90 patients, enhanced voice outcomes were achieved and there was diminished need for post-treatment phonosurgical reconstruction. However, the initial pilot study examining oncologic efficacy had a limited number of patients and most did not have 3-year follow-up. Consequently, further analysis of the oncologic efficacy is valuable. Method: Retrospective review. Results: One hundred seventeen patients (T1a-71, T1b-11, T2a-10, T2b-25) underwent potassium-titanyl-phosphate (KTP) laser treatment of early glottic cancer with a minimum 3-year follow-up (average = 53 months). The “b” designation delineated bilateral disease. Disease control for T1 and T2 lesions was 96% (79/82) and 80% (28/35), respectively. All 10 recurrences were treated with radiotherapy. Fifty percent (5/10) were controlled with radiotherapy, and the other 5 died of disease. Larynx preservation and survival were achieved in 99% (81/82) with T1 disease and 89% (31/35) with T2 disease. Conclusion: This investigation provides further evidence that angiolytic KTP laser removal of early glottic cancer with ultra-narrow margins is an effective oncologic treatment strategy. Radiotherapy was preserved for future use in more than 90% of patients. Since a majority of patients are referred by an otolaryngologist to undergo treatment of early glottic cancer with radiotherapy, this investigation provides compelling information to reappraise this paradigm.
