Laryngoscope Investig Otolaryngol 2023; 8:1579-1583. [PMID: 38130264 PMCID: PMC10731511 DOI: 10.1002/lio2.1184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 08/31/2023] [Accepted: 10/11/2023] [Indexed: 12/23/2023] Open
Abstract
Objectives The current literature provides limited guidance on the management of positive margins (PMs) following transoral laser microsurgery (TLM) for glottic squamous cell carcinoma (SCC). Long-term data exploring the treatment of PMs with both initial observation and re-resection are limited. Our objective was to determine the optimal treatment for PM patients following TLM for glottic SCC. Methods Clinical information on glottic SCC patients with PMs following treatment with TLM was prospectively collected at our institution from 2007 to 2018. We use a laryngeal template during the initial TLM where the area of resection is outlined for future reference. Data were compared with univariate analysis and survival plots were generated using the Kaplan-Meier method. Results A total of 29 patients with PMs were treated with either re-resection (19 patients), close observation (6 patients), or adjuvant radiation alone (4 patients). Re-resection patients had SCC or severe dysplasia on initial margin pathology and 23% with early-stage disease had recurrence (T1-T2). Five (83%) patients who underwent close observation required re-resection based on clinical suspicion of recurrence (confirmed on final pathology), which was significantly different from the re-resection patients (p < .05). Close observation was therefore discontinued as a management of PMs. Four patients (21%) had no residual malignancy on re-resection specimens. Deep margins only accounted for 17% of all PMs. Disease-specific survival for all PM patients at 5 years was 82.4% (SE 9.6%, CI 53.4%-91.6%). Conclusions Our long-term experience with treating early-stage glottic SCC with TLM supports re-resection as an appropriate management for cases of PMs. Level of Evidence 4.

Abstract
Radiology has always been an important component in the evaluation of patients with head and neck cancers. Images that are appropriately acquired and systematically interpreted provide comprehensive information on local, regional, and distant disease extent. This impacts treatment decisions for primary or recurrent disease, and aids in prognostication and patient counselling. The recent significant advances in technology and instrumentation for treatment of head neck cancers have taken place in parallel with an increasing sophistication in radiodiagnostic systems. This is especially true for laryngeal neoplasms where there is now greater focus on functional outcomes and personalised treatment, thus expanding the scope and value of imaging. PURPOSE To formulate evidence-based guidelines on imaging for cancers of the larynx, from diagnosis and staging to monitoring of disease control after completion of treatment. METHODS AND MATERIALS A multidisciplinary analysis of current guidelines and published studies on the topic was performed. RESULTS On the basis of evidence gathered, guidelines were drawn up; optimal suggestions were included for low-resource situations. CONCLUSION These guidelines are intended as an aid to all clinicians dealing with patients of laryngeal cancers. It is hoped that these will be instrumental in facilitating patient care, and in improving outcomes.

T1a Glottic Cancer: Advances in Vocal Outcome Assessment after Transoral CO 2-Laser Microsurgery Using the VEM. J Clin Med 2021; 10:jcm10061250. [PMID: 33802971 PMCID: PMC8002749 DOI: 10.3390/jcm10061250] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 03/10/2021] [Accepted: 03/15/2021] [Indexed: 12/18/2022] Open
Abstract
Patients with unilateral vocal fold cancer (T1a) have a favorable prognosis. In addition to the oncological results of CO2 transoral laser microsurgery (TOLMS), voice function is among the outcome measures. Previous early glottic cancer studies have reported voice function in patients grouped into combined T stages (Tis, T1, T2) and merged cordectomy types (lesser- vs. larger-extent cordectomies). Some authors have questioned the value of objective vocal parameters. Therefore, the purpose of this exploratory prospective study was to investigate TOLMS-associated oncological and vocal outcomes in 60 T1a patients, applying the ELS protocols for cordectomy classification and voice assessment. Pre- and postoperative voice function analysis included: Vocal Extent Measure (VEM), Dysphonia Severity Index (DSI), auditory-perceptual assessment (GRB), and 9-item Voice Handicap Index (VHI-9i). Altogether, 51 subjects (43 male, eight female, mean age 65 years) completed the study. The 5-year recurrence-free, overall, and disease-specific survival rates (Kaplan–Meier method) were 71.4%, 94.4%, and 100.0%. Voice function was preserved; the objective parameter VEM (64 ± 33 vs. 83 ± 31; mean ± SD) and subjective vocal measures (G: 1.9 ± 0.7 vs. 1.3 ± 0.7; VHI-9i: 18 ± 8 vs. 9 ± 9) even improved significantly (p < 0.001). The VEM best reflected self-perceived voice impairment. It represents a sensitive measure of voice function for quantification of vocal performance.

Abstract
INTRODUCTION Recurrent early glottic cancer (rEGC) poses several issues in terms of timely diagnosis, correct re-staging, and treatment. We want to critically review the latest evidence about rEGC considering its epidemiology, biology, diagnostic challenges, and treatment strategies. METHODS A systematic search of the literature using PubMed from 1990 to October 31, 2020 was performed. RESULTS There are many different treatment options available (open surgery, transoral mini-invasive surgery, radiotherapy), and many factors related to the patient's status and previous treatments must be considered when planning the best management strategy for rEGC. While its overall prognosis remains satisfactory, it is of the utmost importance to appreciate all the clinical implications derived from the choice of the initial therapeutic modality, and from a correct primary and recurrent staging. CONCLUSION The balance between oncological and voice and swallowing functions represents the fundamental principle underlying rEGC management. Future studies should focus on molecular profiling of rEGC, and on the results of the emerging radiation delivery techniques and mini-invasive procedures.

Abstract
Background This study aims to investigate the clinical efficacy of transoral laser microsurgery and open partial laryngectomy (OPL) in treating T1-2 laryngeal cancer. Methods A retrospective analysis was conducted of 182 patients with T1-2 cancer with anterior vocal commissure (AVC) involvement. The local control (LC), disease-free survival (DFS) and overall survival (OS) rates at 5-year follow-up and the influencing factors were analyzed. Results No significant difference was observed in the LC or DFS rates between the two groups at 3- and 5-year follow-up. No significant difference was found between the two groups with T1-stage disease. The 5-year LC rates were significantly different from patients with grade 3 or 4 tumors on indirect laryngoscopy and patients with class III or IV tumors on the modified Mallampati test (MMT) (log-rank test: χ2=8.037, P=0.005). The 3-year LC rate of OPL in the depth of pathological infiltration (3-5 mm) group was found to be significantly higher than that of TLM. Significant differences in pathological infiltration depth (3-5 mm) existed between the two groups (log-rank test: χ2=5.786, P=0.016). Conclusions T1 lesions are generally limited and superficial, and laser surgery can be well-controlled. For patients with difficult airway exposure, surgeons should have extensive surgical experience and skills. It is recommended that a variety of equipment should be ready so that surgeons can convert to open surgery at any time. For patients with a deep infiltration depth, surgeons should examine laryngoscopy imaging results before surgery.

Abstract
BACKGROUND Machine learning (ML) algorithms may predict patients who will require salvage total laryngectomy (STL) after primary radiotherapy with or without chemotherapy for laryngeal squamous cell carcinoma (SCC). METHODS Patients treated for T1-T3a laryngeal SCC were identified from the National Cancer Database. Multiple ML algorithms were trained to predict which patients would go on to require STL after primary nonsurgical treatment. RESULTS A total of 16 440 cases were included. The best classification performance was achieved with a gradient boosting algorithm, which achieved accuracy of 76.0% (95% CI 74.5-77.5) and area under the curve = 0.762. The most important variables used to construct the model were distance from residence to treating facility and days from diagnosis to start of treatment. CONCLUSION We can identify patients likely to fail primary radiotherapy with or without chemotherapy and who will go on to require STL by applying ML techniques and argue for high-quality, multidisciplinary regionalized care.

Abstract
OBJECTIVES Early-stage glottic cancer (cT1-T2 cN0) may be treated by primary surgery or radiation. Elective treatment of the neck in clinically N0 disease is usually not performed due to low rates of regional lymph node metastasis. This study examines the role of elective neck dissection (END) and rate of occult nodal metastasis in cT1-T2 cN0 glottic cancer treated with primary surgery. STUDY DESIGN Retrospective cohort study. METHODS The National Cancer Database was used to identify patients treated for early-stage glottic cancer. Demographic variables, disease characteristics, and overall survival were compared between the subgroups of patients who did and did not receive END. Factors predictive of occult lymph node metastasis were also identified using a multivariate logistic regression model. RESULTS Thirty-eight percent of the 991 patients in this cohort underwent END. Younger age, treatment at an academic facility, advanced T-stage, and higher tumor grade were associated with receiving END. Sixteen percent of the 372 patients undergoing END had occult nodal metastasis. Higher tumor histopathologic grade was associated with occult metastasis (P = .004). While undergoing END did not affect significantly survival, those with occult metastasis had poorer survival (P < .001). CONCLUSIONS END should be considered in cT1-T2 N0 glottic cancers with poorly differentiated or undifferentiated tumor histopathology. While END itself may not improve overall survival, identification of occult nodal metastasis is an important finding for prognostication.

Abstract
INTRODUCTION Narrowband imaging (NBI) is a special endoscopic optical enhancement setting allowing better visualization of mucosal microvasculature compared to white light endoscopy. This study evaluates the validity of NBI using the Ni classification in the detection and differentiation of severe dysplasia (SD) and glottic squamous cell carcinoma (SCC). METHODS Patients with suspicious vocal cord lesions underwent conventional white light endoscopy followed by clinically indicated biopsy. At the same time, NBI images were obtained and graded independently. Lesions were graded from I to V according to the Ni classification and compared to histopathological findings. RESULTS Fifty-two patients were included in this study (40 SCC and 12 SD). The sensitivity and specificity of NBI in diagnosing laryngeal cancer was 95.0% (CI, 83.9%-99.4%) and 83.3% (CI, 51.6%-97.9%), respectively. The negative likelihood ratio was 0.06. Higher Ni grades correlated very strongly with more advanced disease. CONCLUSIONS NBI using the Ni classification is a sensitive diagnostic tool for the detection and differentiation of early neoplastic and preneoplastic glottic lesions. As higher Ni classification correlates strongly with advanced disease, it serves as a useful adjunct to white light endoscopy in the diagnosis of laryngeal cancer.Level of Evidence: Level IV.

Abstract
AIM Treatment strategies in laryngeal squamous cell cancer (LSCC) straddle the need for long term survival and tumor control as well as preservation of laryngeal function as far as possible. We sought to identify prognostic factors affecting LSCC outcomes in our population. METHODS Clinical characteristics, treatments and survival outcomes of patients with LSCC were analysed. Baseline comorbidity data was collected and age-adjusted Charlson Comorbidity Index (aCCI) was calculated. Outcomes of overall survival (OS), progression-free survival (PFS) and laryngectomy-free survival (LFS) were evaluated. RESULTS Two hundred and fifteen patients were included, 170 (79%) underwent primary radiation/ chemoradiation and the remainder upfront surgery with adjuvant therapy where indicated. The majority of patients were male, Chinese and current/ex-smokers. Presence of comorbidity was common with median aCCI of 3. Median OS was 5.8 years. On multivariable analyses, high aCCI and advanced nodal status were associated with inferior OS (HR 1.24 per one point increase in aCCI, P<0.001 and HR 3.52; p<0.001 respectively), inferior PFS (HR 1.14; p = 0.007 and HR 3.23; p<0.001 respectively) and poorer LFS (HR 1.19; p = 0.001 and HR 2.95; p<0.001 respectively). Higher tumor (T) stage was associated with inferior OS and LFS (HR 1.61; p = 0.02 and HR 1.91; p = 0.01 respectively). CONCLUSION In our Asian population, the presence of comorbidities and high nodal status were associated with inferior OS, PFS and LFS whilst high T stage was associated with inferior LFS and OS.

Abstract
Carbon Dioxide transoral laser microsurgery represents a reliable option for the treatment of early glottic carcinoma (Tis–T2), with good functional and oncological outcomes, nowadays representing one of the main options in larynx preservation protocols. The development and improvement of laser devices means surgeons are able to use more precise instruments compared with classic cold dissection in laser-assisted phonosurgery. Secondary effects on voice, swallowing, or quality of life as well as complications have been well documented. Also, with the introduction of a new proposal for staging systems following the principle of the three-dimensional map of isoprognostic zones, the use of narrow-band imaging in clinical evaluation and intraoperative, and the implementation of diffusion-weighted magnetic resonance during preoperative evaluation, the development of new tools to improve surgical quality and preliminary reports regarding the use of carbon dioxide laser in transoral robotic surgery suggests an exciting future for this technique.

Abstract
OBJECTIVE The main goal was to compare the clinical data of patients with T1 and T2 glottic cancer treated with CO2 transoral laser microlaryngoscopy (TLM) in the Tertiary Referral University Department of Otolaryngology, Head Neck Surgery, Poznan and the local Department of Otolaryngology, Oncology and Maxillofacial Surgery, Bydgoszcz. MATERIAL AND METHODS Unified databases for the 7-year period January 2005-December 2011 were created to compare these two cohorts. The database contained 341 patients: 231 from the tertiary center and 110 from the local department, of which 298 (87%) were men, and 43 (13%) were women. RESULTS Cordectomy type I-IV was performed in 250 (73%) patients, cordectomy type V-VI in 84 (25%) patients, and cordectomy enlarged to epiglottic petiole in 7 (2%) patients. Local recurrence was observed in 96 (28%) cases. Among these cases, 81 (87.5%) patients had salvage surgery: 43 re-cordectomy, 10 open partial laryngectomy, and 28 total laryngectomy. The outcomes for the whole cohort, Tertiary Referral Center and Local Department respectively were as follows: larynx preservation rate was 91.8%, 93.6%, and 88%; 3-year disease specific survival was 97.4%, 97.9%, and 93.3%; 3-year overall survival was 93.5%, 96.6%, and 85.5%; 5-year disease specific survival was 95.2%, 95.2%, and 96.3%; and 5-year overall survival was 84.5%, 88.7%, and 76%, respectively. CONCLUSION Comparison of the cohorts showed that outcomes of primary treatment were similar but there were noticeable differences in salvage treatment efficacy, favoring patients from the Tertiary Referral Center.

Abstract
PURPOSE OF REVIEW To give an overview of the evolvement of transoral laser microsurgery (TLM) in the treatment of early glottic carcinoma and highlight the contribution of recent literature. RECENT FINDINGS The indications and limits of TLM have been well specified. Effects on swallowing have been well documented. Introduction of narrow-band imaging (NBI) and diffusion-weighted magnetic resonance has been shown of additional value for outcome. The first reports on transoral robotic surgery show that it may be of added value in the future. SUMMARY TLM for early glottic carcinoma (Tis-T2) has very good oncological outcomes with indications of higher larynx preservation in TLM than that in radiotherapy. The anterior commissure is a risk factor if involved in the cranio-caudal plane, and reduced vocal fold mobility is a risk factor when this is due to arytenoid involvement. The best voice results are achieved when the anterior commissure can be left intact along with part of the vocal fold muscle although even in larger resections, patient self-reported voice handicap is still limited.

Abstract
Answer questions and earn CME/CNE Laryngeal cancer remains one of the most common tumors of the respiratory tract. Fortunately, significant advancements have been made over the past decade in the treatment of laryngeal cancer. Although surgery has been the historical mainstay for localized disease and still is an integral part of treatment, nonsurgical options like radiation and systemic therapy have emerged as viable options. In addition, in the metastatic setting, novel agents are showing promise for this patient population. The care for patients with laryngeal cancer continues to evolve and truly requires a multidisciplinary team-based approach. Unique morbidities, such as loss of natural voice, respiration, and airway protection during swallowing, are observed with this disease and require special consideration.

Abstract
Objective We aimed to develop and validate an ex vivo dissection station for endolaryngeal surgery suitable for different kinds of laryngeal specimen and any type of operating technique (CO2 laser, cold instruments by endoscopic or microscopic techniques). Study Design Experimental construction and validation of a highly specialized dissection station. Setting Laboratory and international dissection course. Methods We designed a lightweight dissection station made of polycarbonate resin approved for use with a CO2 laser. The cylindrical box hosts an articulated laryngeal support. The laryngoscope is positioned on an articulated arm, which is fixed on the construction’s footplate. Validation of the larynx box was performed during an international dissection course on laryngeal surgery held in January 2016. Results We assessed the suitability of our novel dissection station among specialized laryngologists with a mean experience of 14 years. Feedback from the participants was very positive, with a mean general impression of 9.5 (out of 10 points) and a recommendation score of 9.6 for further use. Its utility in transforming the taught surgical steps into daily practice has been highly recognized, with a score of 9.5. Conclusion The lightweight and transparent larynx box is suitable for any kind of laryngeal specimen, and any surgical intervention can be taught at reasonable cost. It is safe and suitable for use with CO2 lasers. Validation among experienced surgeons revealed its suitability in the teaching of endolaryngeal microsurgery and laser surgery.

Abstract
Objective Laryngeal cancer most commonly arises from the glottis. Comparable outcomes in survival have been shown in patients with early glottic squamous cell carcinoma treated with either surgery or radiotherapy. Study Design and Setting Administrative database study. Subjects and Methods The US National Cancer Institute’s SEER database (Surveillance, Epidemiology, and End Results) was queried for cases of early glottic cancer (T1-T2N0M0, 1988-2012). We identified 13,312 qualifying cases. Patient demographics, therapeutic measures, and survival outcomes were examined with appropriate univariate and multivariate analyses. Results Early glottic cancer has a mean age at diagnosis of 64.8 ± 11.6 years and a male:female ratio of 6.9:1. The most common treatment modality was radiotherapy alone (51.6%), followed by combination therapy with surgery first (31.5%). Overall, the 5-year disease-specific survival (DSS) rate was 88.4%. When stratified by treatment modality and stage, 5-year DSS for T1 tumors was 93.2% with surgery alone and 89.0% with radiation alone ( P < .0001). With combination therapy, the 5-year DSS was 91.3% for surgery first and 84.9% for radiation first ( P = .0239). In T2 tumors, 5-year DSS was improved with single-modality therapy versus multimodality therapy (81.1% vs 76.4; P = .0255). Conclusion In T1 disease, surgery alone shows improved 5-year DSS versus radiation alone, but this difference was not observed in T2 tumors. Additionally, surgery, rather than radiation, shows improved 5-year DSS when implemented as a first-line therapy. Combination therapy does not show improved 5-year DSS for early glottic cancer.

Abstract
BACKGROUND The oncologic impact of surgical margins after transoral laser microsurgery (TLM) for T1 and T2 glottic carcinoma is controversial. The purpose of this study was to assess the prognostic value of margin status in terms of local control. METHODS Records of 266 patients treated from 1990 to 2013 were evaluated. Patients with previous cordectomy or without preoperative CT scan were excluded from the study. RESULTS A total 110 patients (85 T1a, 8 T1b, and 17 T2) were enrolled. A local recurrence was observed in 23 patients. Five-year disease-free survival was significantly impaired in patients with positive margins (p = .009) and in patients with deep involvement of the vocal muscle (p = .004). CONCLUSION The present study shows that invaded margin is a factor of poor local control even though laser vaporization was systematically applied after resection. In case of deep vocal fold involvement, TLM should be extended beyond the vocal muscle to improve local control. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1804-1809, 2016.
