Abstract
BACKGROUND Laryngocarcinoma (LC) is a common malignant tumor of the head and neck, accounting for 1% to 5% of human tumors. The primary objective of the present study was to evaluate the survival time of patients with LC at different sites. METHODS Information concerning patients with LC was extracted from the Surveillance, Epidemiology, and End Results (SEER) database between 1975 and 2016. RESULTS In total, 16 255 patients with LC were selected from the SEER database. Among all patients, 80.2% were male; males also predominated in each tumor site subgroup. Most of the patients were aged between 60 and 69 years, had white ethnicity, were single, and had American Joint Committee on Cancer (AJCC) stage I cancer with T1, N0, and M0. The present study investigated the role of interventions in all LCs at different AJCC stages. Across the whole population, regardless of the intervention used, survival increased in patients at any cancer site. CONCLUSIONS The study found that male sex, age ≥80 years, black ethnicity, single status, T4, N4, M1, and AJCC stage IV were associated with higher mortality rates at all sites of LC. Aggressive interventions, especially surgery and radiotherapy, may improve survival in patients with LC at different sites and with different AJCC stages.

Daily fraction dose-adjusted radiotherapy policy to avoid prolonging the overall treatment time for early glottic squamous cell carcinoma: a single-institutional retrospective study. JOURNAL OF RADIATION RESEARCH 2024; 65:63-70.

Abstract
The objective of this study was to determine the outcomes of radical radiotherapy for early glottic squamous cell carcinoma (EGSCC) with the policy of increasing the fraction size during radiotherapy when the overall treatment time (OTT) was expected to be prolonged. Patients diagnosed with clinical T1-2N0M0 EGSCC, who were treated with radical radiotherapy between 2008 and 2019 at Hokkaido University Hospital, were included. Patients received 66 Gy in 33 fractions for T1 disease and 70 Gy in 35 fractions for T2 disease as our standard regimen (usual group [UG]). If the OTT was expected to extend for >1 week, the dose fraction size was increased from 2.0 to 2.5 Gy from the beginning or during radiotherapy (adjusted group [AG]). At this time, we performed a statistical analysis between UG and AG. In total, 116 patients were identified, and the treatment schedules of 29 patients were adjusted. The median follow-up was 60.9 months. In the T1 group, the cumulative 5-year local failure rate was 12.0% in the AG and 15.4% in the UG, and in the T2 group, the rate was 40.7% in the AG and 25.3% in the UG. There were no significant differences between the AG and UG. Similarly, no significant differences were observed for overall survival and progression-free survival rates. Our single-institutional retrospective analysis of EGSCC patients suggested that a method of adjusting the radiotherapy schedule to increase fraction size from the beginning or during the course may be effective in maintaining treatment outcomes.

Yang Y, Wang YL, Wei LZ, Wang JX, Huang FT, Huang GW. Is CO 2 laser microsurgery better than radiotherapy in early glottic cancer: a meta-analysis. Lasers Med Sci 2023; 38:223. [PMID: 37758965 PMCID: PMC10533611 DOI: 10.1007/s10103-023-03890-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 09/19/2023] [Indexed: 09/29/2023]
Abstract
The choice between radiotherapy (RT) and CO2 laser surgery (CO2-LS) for early glottic cancer remains controversial. We systematically examined electronic databases in order to identify prospective trials comparing patients who had undergone CO2-LS or RT to treat early glottic cancer. Eleven studies involving 1053 patients were included. In the selected literature, the parameter setting of CO2 laser equipment can be summarized as wavelength 10.6 µm, superpulsed mode, continuous setting, power tailored on target structures (1-3 W for subtle resections and 4-15 W for cutting a larger tumor), and approximately 2080-3900 W/cm2 of laser energy. Using RevMan 5.3, we estimated pooled odds ratios (ORs) for dichotomous variables and pooled mean differences (MDs) for continuous variables, along with associated 95% confidence intervals (CIs). The heterogeneity in the treatment variables was measured using Higgins' inconsistency test and expressed as I2 values. The continuous variables were then depicted as histograms developed using PlotDigitizer 2.6.8. Compared to patients treated with CO2-LS, those treated with RT had better jitter (MD 1.27%, 95% CI 1.21 ~ 1.32, P < 0.001), and high scores on the "Grade (MD 6.54, 95% CI 5.31 ~ 7.76, P < 0.001), Breathiness (MD 9.08, 95% CI 4.02 ~ 14.13, P < 0.001), Asthenia (MD 2.13, 95% CI 0.29 ~ 3.98, P = 0.02), and Strain (MD 3.32, 95% CI 0.57 ~ 6.07, P = 0.02)" scale. Patients treated with CO2-LS had worse local control rates (OR 3.14, 95% CI 1.52 ~ 6.48, P = 0.002) while lower incidence of second primary tumor (OR 0.30, 95% CI 0.15 ~ 0.61, P < 0.001). It is hoped that retrospective analysis can provide suggestions for early glottis patients to choose personalized treatment.

Overview of glottic laryngeal cancer treatment recommendation changes in the NCCN guidelines from 2011 to 2022. Cancer Rep (Hoboken) 2023; 6:e1837. [PMID: 37288471 PMCID: PMC10432469 DOI: 10.1002/cnr2.1837] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 04/27/2023] [Accepted: 05/09/2023] [Indexed: 06/09/2023] Open
Abstract
BACKGROUND The treatment of glottic cancer remains challenging, especially with regard to morbidity reduction and larynx preservation rates. The National Comprehensive Cancer Network (NCCN) has published guidelines to aid decision-making about this treatment according to the tumor site, clinical stage, and patient medical status. AIM The present review was conducted to identify changes in the NCCN guidelines for glottic cancer treatment made between 2011 and 2022 and to describe the published evidence concerning glottic cancer treatment and oncological outcomes in the same time period. METHODS AND RESULTS Clinical practice guidelines for head and neck cancer published from 2011 up to 2022 were obtained from the NCCN website (www.NCCN.org). Data on glottic cancer treatment recommendations were extracted, and descriptive analysis was performed. In addition, a review of literature registered in the PubMed database was performed to obtain data on glottic cancer management protocols and treatment outcomes from randomized controlled trials, systematic reviews, and meta-analyses published from 2011 to 2022. In total, 24 NCCN guidelines and updates and 68 relevant studies included in the PubMed database were identified. The main guideline changes made pertained to surgical and systemic therapies, the consideration of adverse features, and new options for the treatment of metastatic disease at initial presentation. Early-stage glottic cancer received the most research attention, with transoral endoscopic laser surgery and radiotherapy assessed and compared as the main treatment modalities. Reported associations between treatment types and survival rates for this stage of glottic cancer appear to be similar, but functional outcomes can be highly compromised. CONCLUSION NCCN panel members provide updated recommendations based on currently accepted treatment approaches for glottic cancer, constantly reviewing new surgical and non-surgical techniques. The guidelines support decision-making about glottic cancer treatment that should be individualized and prioritize patients' quality of life, functionality, and preferences.

Abstract
OBJECTIVES This study investigates vocal outcome after cordectomy by transoral CO2 laser microsurgery (TLM-cordectomy) in patients with laryngeal intra-epithelial neoplasia (LIN) or non-neoplastic lesions (NNL), for improved individual patient advice and potential adjustment of national treatment strategy by which patients suspected to have glottic LIN or T1a cancer are offered TLM-cordectomy, without prior biopsy. STUDY DESIGN Prospective, longitudinal, quasi-experimental time series. METHODS Consecutively included patients (n = 155) with LIN (n = 84) or NNL (n = 71) who underwent voice assessments before and after TLM-cordectomy. The multi-dimensional voice assessment protocol comprised voice and speech range profiles, aerodynamics, acoustic analysis, self-evaluated voice handicap, and perceptual auditory voice ratings. RESULTS Median follow-up time was 195 (range 50-1121) days for patients with LIN and 193 (range 69-1294) days for patients with NNL. Statistically significant changes, LIN: in voice handicap index (VHI) and breathiness after TLM-cordectomy. Statistically significant changes, NNL: voice range profile (voice range area, intensity range, and frequency range) and VHI after TLM-cordectomy. All group-wise changes were to less disordered voices. Previous smokers had the largest decreases in VHI and breathiness. Patients with baseline VHI scores >65 had smaller increases in VHI, however 13-19% of the patients had increases in VHI above the clinically relevant threshold after TLM-cordectomy. CONCLUSION Overall, TLM-cordectomy in patients with LIN and NNL improved vocal outcome and our study thus supports the current Danish treatment strategy and improves the basis for proper patient advice. Multi-dimensional voice assessment is suggested preoperatively and six-nine months postoperatively, with focus on individual vocal differences and voice demands.

Change in Voice Quality after Radiotherapy for Early Glottic Cancer. Cancers (Basel) 2022; 14:cancers14122993.

Abstract
Our aim was to track the changes in voice quality for two years after radiotherapy (RT) for early glottic cancer. A videoendostroboscopy, subjective patient and phoniatrician voice assessments, a Voice Handicap Index questionnaire, and objective acoustic measurements (F0, jitter, shimmer, maximal phonation time) were performed on 50 patients with T1 glottic carcinomas at 3, 12, and 24 months post-RT. The results were compared between the subsequent assessments, and between the assessments at 3 months and 24 months post-RT. The stroboscopy showed a gradual progression of fibrosis of the vocal folds with a significant difference apparent when the assessments at 3 months and 24 months were compared (p < 0.001). Almost all of the subjective assessments of voice quality showed an improvement during the first 2 years, but significant differences were noted at 24 months. Jitter and shimmer deteriorated in the first year after RT with a significant deterioration noticed between the sixth and twelfth months (p = 0.048 and p = 0.002, respectively). Two years after RT, only 8/50 (16%) patients had normal voices. The main reasons for a decreased voice quality after RT for early glottic cancer were post-RT changes in the larynx. Despite a significant improvement in the voice after RT shown in a few of the evaluation methods, only a minority of the patients had a normal voice two years post-RT.

Abstract
Early-stage squamous cell cancer (SCC) of the glottis has a good prognosis. Therefore, patients have long survival outcomes and may potentially suffer from late toxicities of radiotherapy. Radiotherapy with a conventional parallel-opposed-pair or anterior-oblique beam arrangements for stage 1 and 2 glottic SCC have field borders that traditionally cover the entire larynx, exposing organs-at-risk (e.g. carotid arteries, contralateral vocal cord, contralateral arytenoid and inferior pharyngeal constrictor muscles) to high radiation doses. The potential long-term risk of cerebrovascular events has attracted much attention to the dose that carotid arteries receive. Swallow and respiratory motion of laryngeal structures has been an important factor that previously limited reduction of the radiation treatment volume. Motion has been evaluated using multiple imaging modalities and this information has been used to calculate PTV margins for generation of more limited target volumes. This review discusses the current literature surrounding dose-effect relationships for various organs-at-risk and the late toxicities that are associated with them. This article also reviews the currently available data and effects of laryngeal motions on dosimetry to the primary target. We also review the current limitations and benefits of a more targeted approach of radiotherapy for early-stage glottic SCCs and the evolution of CT-based IGRT and MR-guided radiotherapy techniques that may facilitate a shift away from a conventional 3D-conformal radiotherapy approach.

Abstract
The Radiation Therapy Oncology Group 91-11 trial and US Veterans Affairs trial revolutionized the way locally advanced laryngeal cancers are treated. Adjuvant therapies exist aimed toward laryngeal preservation using docetaxel, cisplatin, and fluorouracil. Cetuximab is a cornerstone of treatment due to the large role of epidermal growth factor receptor in laryngeal and hypopharyngeal carcinomas. In addition, the immune system is vital in the prevention of recurrence, and various immunomodulators against programmed cell death receptor 1 are being investigated. Multidisciplinary management of the patient with laryngeal and hypopharyngeal is key, as many vital functions are affected by this devastating disease.

Vocal-cord Only vs. Complete Laryngeal radiation (VOCAL): a randomized multicentric Bayesian phase II trial. BMC Cancer 2021; 21:446.

Abstract
BACKGROUND Radiotherapy, along with laser surgery, is considered a standard treatment option for patients with early glottic squamous cell cancer (SCC). Historically, patients have received complete larynx radiotherapy (CL-RT) due to fear of swallowing and respiratory laryngeal motion and this remains the standard approach in many academic institutions. Local control (LC) rates with CL-RT have been excellent, however this treatment can carry significant toxicities include adverse voice and swallowing outcomes, along with increased long-term risk of cerebrovascular morbidity. A recent retrospective study reported improved voice quality and similar local control outcomes with focused vocal cord radiotherapy (VC-RT) compared to CL-RT. There is currently no prospective evidence on the safety of VC-RT. The primary objective of this Bayesian Phase II trial is to compare the LC of VC-RT to that of CL-RT in patients with T1N0 glottic SCC. METHODS One hundred and fifty-five patients with T1a-b N0 SCC of the true vocal cords that are n ot candidate or declined laser surgery, will be randomized in a 1:3 ratio the control arm (CL-RT) and the experimental arm (VC-RT). Randomisation will be stratified by tumor stage (T1a/T1b) and by site (each site will be allowed to select one preferred radiation dose regimen, to be used in both arms). CL-RT volumes will correspond to the conventional RT volumes, with the planning target volume extending from the top of thyroid cartilage lamina superiorly to the bottom of the cricoid inferiorly. VC-RT volumes will include the involved vocal cord(s) and a margin accounting for respiration and set-up uncertainty. The primary endpoint will be LC at 2-years, while secondary endpoints will include patient-reported outcomes (voice impairment, dysphagia and symptom burden), acute and late toxicity radiation-induced toxicity, overall survival, progression free survival, as well as an optional component of acoustic and objective measures of voice analysis using the Consensus Auditory-Perceptual Evaluation of Voice. DISCUSSION This study would constitute the first prospective evidence on the efficacy and safety of VC-RT in early glottic cancer. If positive, this study would result in the adoption of VC-RT as standard approach in early glottic cancer.

Radiotherapy versus partial laryngectomy in the management of early glottic cancer with anterior commissure involvement: A propensity score matched study with 256 patients. Oral Oncol 2021; 116:105230. [PMID: 33647869 DOI: 10.1016/j.oraloncology.2021.105230] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 02/09/2021] [Accepted: 02/11/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVES The study was intended to compare the outcomes for T1-T2N0M0 glottic squamous cell carcinoma with anterior commissure involvement who had undergone partial laryngectomy (PL) or radiotherapy (RT). MATERIALS AND METHODS We retrospectively analyzed 256 patients who were treated by RT (n = 70) or PL (n = 186). Patients received prophylactic irradiation of the neck in RT group whereas PL was not associated with lymphadenectomy. Propensity score matching (PSM) was used to eliminate the baseline variations. RESULTS The average age of the RT group (67 years) was significantly higher than that of the PL (59 years). Local recurrence was noted in 14 patients of the RT group and 22 of the PL. While regional recurrence was noted in only 1 patient of the RT group and 23 of the PL. After PSM, the 5-year overall survival (82.8% vs. 83.9%, p = 0.302), 5-year cancer-specific survival (88.3% vs. 89.7%, p = 0.793), 5-year local relapse-free survival (79.3% vs. 84.5%, p = 0.127) were not significantly different between two groups. However, 5-year regional relapse-free survival in the RT group was significantly better than that in the PL (100% vs. 87.1%, p = 0.014). In the PL group, infection, granuloma, laryngeal stenosis, chylous leakage, and pharyngeal fistula were reported in six, 11, 12, one, and two patients, respectively. CONCLUSIONS RT resulted in comparable rates of survival, local control, and larynx preservation compared to PL. However, RT was associated with higher regional control rate. The complication rates were extremely low in RT group.

Abstract
The option of T1a glottic cancer treatments remarkably varied in different countries. This study aimed to construct predictive models to predict overall survival (OS) and cancer-specific survival (CSS) of patients with initially diagnosed T1a glottic cancer. And we used propensity score matching (PSM) to reassess the effect of treatments.Data of patients with initially diagnosed T1a glottic cancer were extracted from the Surveillance, Epidemiology, and End Results database. Patients with complete information were randomly divided into the training and the validation cohorts (7:3). Cox regression was conducted to screen significant predictors of the OS and the CSS. PSM was performed to mimic randomized controlled trials. Survival analyses were performed by Kaplan-Meier survival methods, and log-rank tests were utilized.A total of 2342 patients met the inclusion criteria. Survival analyses showed that patients who underwent primary site surgery would have better OS and CSS. Univariate analyses and multivariate analyses proved that stage, N stage, primary site surgery, and chemotherapy significantly affected both the OS and the CSS. Predictive nomograms were established to predict patients' prognosis. Finally, the OS and the CSS for patients who underwent primary site surgery alone were significantly longer than those who underwent radiation alone before and after PSM.We constructed nomograms predicting the OS and the CSS of patients with initially diagnosed T1a glottic cancer. Compared to our previous studies, this study indicated that primary site surgery may be superior to radiation and chemotherapy. At present, chemotherapy should be not recommended for T1a glottic cancer patients.

Abstract
Objective: To analyze the clinical efficacy of external beam radiation therapy (EBRT) vs transoral laser microsurgery (TLM) in patients with early glottic laryngeal carcinoma (T1-T2N0) and the effect of treatment choice on vocal function. Methods: A retrospective analysis of patients with T1-T2N0 glottic laryngeal carcinoma who underwent EBRT or TLM between January 2012 and December 2018 in PUMCH. The Kaplan-Meier method was used to analyze local control, progression-free survival and overall survival, and the VHI-30 scale was used to evaluate the effects of EBRT and TLM on vocal function. Results: A total of 185 patients, all with pathologically confirmed squamous cell carcinoma, were enrolled. The median age was 62 years (38-88). N0 disease was confirmed by imaging: 142/185 (76.76%) patients had T1N0 disease, and 43/185 patients (23.24%) had T2/N0 disease. A total of 91/195 (49.19%) patients received an EBRT dose of 66-70 Gy/30-35f, at 2.0-2.3 Gy/f. 94/185 (50.81%) patients received TLM. The median follow-up time was 42 months (12-92), and the 3-year LC, PFS, and OS rates for the EBRT and TLM groups were 96.9% vs 94.1%(p=0.750), 95.3% vs 93.1%(p=0.993) and 93.3% vs 95.4%(p=0.467), respectively. The VHI-30 scales were used at the baseline showed no significant difference between the two groups 19.20±3.324 vs 21.65±9.80 (p=0.250), but the EBRT group had a low voice handicap after treatment, 10.24±6.093 vs 19.45±5.112 (p=0.001) (6 months) and 9.45±5.112 vs 14.97±7.741 (12 months). No CTCAE grade 3 or above side effects were observed in the EBRT group, but 3 cases of vocal cord stenosis were observed in the TLM group. Conclusion: The application of EBRT for early glottic laryngeal carcinoma (T1-T2N0) had an obvious curative effect with high LC and OS rates, no serious side effects, and a low voice handicap rate.

Abstract
Aim The aim of this study was to compare the outcomes, patterns of failure and laryngeal preservation rates in patients with T1N0 glottic cancer treated with surgery or radiotherapy. Materials/methods Retrospective study of T1N0 glottic cancer patients treated in our institution between January 2007 and December 2017. Histologically proven squamous cell carcinoma patients, treated with upfront cordectomy/partial laryngectomy (S group) or radiotherapy (RT group) were included. Elective treatment of the neck was not permitted. Local failure (LF), disease-free survival (DFS), ultimate disease-free survival (UDFS), laryngectomy-free survival (LFS), disease-specific mortality (DSM) and overall survival (OS) were evaluated. Results Two hundred and one patients were eligible (172 S group, 29 RT group), with a median follow-up of 38.8 months. Overall, 33 (16%) patients had a recurrence, 30 (17%) in the S group and 3 (10%) in the RT group. Local failure was the predominant site of failure (28 S, 2 RT). Overall, of all those that were salvaged, 17 (8%) underwent total laryngectomy (15 S, 2 RT). There was no significant difference in the 5-year cumulative incidence of LF (20.8% S, 8.1% RT, p = 0.138), 5-y LFS (85.0% vs. 91.7%, p = 0.809), 5-y DFS (67.5% vs. 82.1%, p = 0.343), 5-y UDFS (82.5% vs. 90.3%, p = 0.647) and 5-y OS (84.5% vs. 90.3%, p = 0.892). Multivariate analysis showed no correlation between initial treatment and the analyzed outcomes. Conclusion Primary surgery or radiotherapy were similar first line options, since they do not differ in all outcomes. Patients' and physician's preferences must be considered when choosing first treatment.

Abstract
The choice of the most appropriate treatment in early-stage glottic cancer with anterior commissure involvement remains controversial. Its therapeutic management is complex because it is a significant prognostic indicator of local control with 37% recurrence, due to the difficulty in establishing tumour extension with understaging of up to 40%, and due to the comparison of results in series on tumours that behave variably as they progress, such as T1a, T1b and T2a with commissure involvement. Furthermore, the complexity of the surgical approach using transoral CO2 laser microsurgery requires surgical skill, appropriate equipment and experience. Aspects to be reviewed in this document are: an updated anatomical definition of the anterior commissure, tumour progression based on histopathological studies, usefulness of videostroboscopy and NBI in diagnostic accuracy, validity of imaging tests, oncological results published in series reviews, systematic reviews and meta-analyses, tumour margin treatment and voice evaluation.Finally, by way of a summary, the document includes a series of recommendations for the treatment of these tumours.

Abstract
Background Radiotherapy (RT) is a successful mode of treatment for early glottic cancer. The aim of the study was to assess voice quality both before and 3 months after successful RT using multimodal methods while also identifying the factors affecting it. Patients and methods In 50 patients with T1 glottic carcinoma, the subjective (patients’ assessment of voice quality [VAS], Voice Handicap Index [VHI] questionnaire, phoniatricians’ assessment using the grade/roughness/ breathiness [GRB] scale), and objective assessments (fundamental laryngeal frequency [F0], jitter, shimmer, maximum phonation time [MPT]) of voice quality were performed before RT and 3 months post-RT. The data on gender, age, extent of the tumors, biopsy types, smoking, local findings, and RT were obtained from the medical documentation. Results Three months after the treatment, VAS, VHI, G and R scores, F0, and MPT significantly improved in comparison with their assessment prior to treatment. Before the treatment, the involvement of the anterior commissure significantly deteriorated jitter (p = 0.044) and the involvement of both vocal folds deteriorated jitter (p = 0.003) and shimmer (p = 0.007). After the RT, F0 was significantly higher in the patients with repeated biopsy than in the others (p = 0.047). In patients with post-RT changes, the B score was significantly higher than in those without post-RT changes (p = 0.029). Conclusions Voice quality already significantly improved three months after the treatment of glottic cancer. The main reason for the decreased voice quality prior to treatment is the tumor’s extent. Post-RT laryngeal changes and repeated biopsies caused more scarring on vocal folds adversely influencing voice quality after the treatment.

Abstract
Laser surgery (LS) or radiotherapy (RT) is normally recommended in early glottic cancer. The objective of this study was to perform a comprehensive meta-analysis of acoustic and perceptual outcomes to compare voice quality of LS or RT in early-stage glottic cancer. Data sources were obtained after searching PubMed, Google Scholar, EBSCO, and RISS using the following search terms: glottic cancer, glottic carcinoma, endoscopic surgery, laser surgery, radiotherapy, radiation, voice, voice quality, and grade, roughness, breathiness, asthenia, and strain (GRBAS) scale. Articles that compared voice outcomes between LS and RT were identified. This meta-analysis included 15 articles with 744 patients, including 400 in the LS group and 344 in the RT group. Random effects models were selected. Forest plots included standardized mean differences, standard errors, variance, 95% confidence intervals (lower limit to upper limit), z-values, and P-values. In perceptual analysis, grade (G) and asthenia (A) of RT were significantly better than LS. There was no statistically significant difference in roughness (R), breath (B), or strain (S) between LS and RT groups. Jitter, shimmer, and noise to harmonic ratio measurements showed significant differences, resulting in enhanced posttreatment effect of RT compared to LS. Results of our meta-analysis suggested that RT might lead to superior voice quality than LS in early glottic cancer.

Abstract
OBJECTIVE Radiotherapy is an option to treat high-grade laryngeal dysplasia. This study aimed to evaluate the use of intensity-modulated radiotherapy, 55 Gy in 20 daily fractions, in treating this disease. METHODS Acute toxicity was evaluated in all 14 patients treated. In 10 patients, functional voice outcome was measured using the Voice Handicap Index, and the Grade, Roughness, Breath, Asthenia, Strain ('GRBAS') scale. These measurements were performed pre-treatment and three months after intensity-modulated radiotherapy. RESULTS All but one patient managed to complete radiotherapy. Acute toxicity was significant (one patient developed grade 4 and three patients developed grade 3 dysphagia). Four patients required hospital admission. In 9 out of 10 patients, radiotherapy improved voice quality. CONCLUSION This radiotherapy regimen using intensity-modulated radiotherapy for laryngeal dysplasia is feasible and provided excellent functional outcome, but acute toxicity was significant. Dose de-escalation can be considered in the framework of clinical trials.

Abstract
There are conflicting reports about whether radiotherapy or surgery is optimal for early‐stage laryngeal squamous cell carcinoma (LSCC), although both have recently been recommended. Patients with T1‐2N0M0 LSCC in the population‐based SEER database who underwent radiotherapy or surgery were reviewed. Propensity score matching was used to eliminate the baseline variations. After matching, 1913 pairs of patients were included. Overall, patients who received radiotherapy had worse cancer‐specific survival than patients with surgery. After stratification, the survival in patients who received radiotherapy was worse with respect to the following characteristics: ≤60 years of age; T1a glottis cancer; well‐differentiated tumors; and with married status. In other patients, survival outcomes were similar in patients who received radiotherapy and underwent surgery. Our results indicate that radiotherapy is not preferable in early‐stage LSCC patients who are ≤60 years of age, have T1a glottis cancer or well‐differentiated tumors, or are married. In other patients, both radiotherapy and surgery are comparable. However, our results cannot be a reference before controlled, prospective trials are performed.

Abstract
OBJECTIVES A meta-analysis was conducted to compare oncologic outcomes for patients of T1a glottic carcinoma who were treated with laser surgery (LS) or radiotherapy (RT). METHODS All related studies published up to October 2016 were acquired by searching PubMed, EMBASE, and Cochrane were conducted by two authors, with the index words: vocal, glottis, larynx, laser, surgery, cordectomy, radiotherapy, radiation, irradiation, carcinoma, and cancer. Relative studies which compared oncologic outcomes between LS and RT were included. RESULTS A total of nine eligible studies were included for the analysis, which contained two prospective studies and seven retrospective studies. LS has increased larynx preservation (OR = 3.86, 95% CI = 1.47-10.13, p = .006) compared with RT group. No statistical difference was observed between LS group and RT group in terms of local control, overall survival, and disease-specific survival. There was a slight trend in terms of local control, overall survival, and disease-specific survival that all favored LS, although all data did not reach the level of statistical significance. CONCLUSIONS The results of this meta-analysis indicate that LS may be a better option for the treatment of T1a glottic carcinoma because patients underwent LS may benefit from increased larynx preservation compared with RT. However, more multi-center randomized controlled trials would be urgently needed to prove these differences.
