Wound healing after transoral angiolytic laser surgery for early glottic carcinoma.

Wound healing after transoral angiolytic laser surgery for early glottic carcinoma was analyzed to identify factors influencing healing and clinical significance of persistent granulation tissue. Retrospective review. A retrospective review of 100 consecutive patients undergoing endoscopic angiolytic laser surgery for T1 and T2 glottic carcinoma was performed. Patients with prior radiation or incomplete data were excluded. Postoperative endoscopic images were analyzed for time to healing, size and location of wound, and presence of granulation tissue. Three blinded, independent raters graded wound appearance and presence of granulation tissue. Seventy-nine patients healed without need for intervention at a median of 3.5 months. Two patients had office-based ablation of granulation without biopsy and healed. The remaining 19 patients had biopsy for granulation tissue. Wounds that underwent biopsy at >3 months were more likely to contain carcinoma (5/6 patients, 83%) than wounds that were biopsied <3 months (2/13 patients, 15%) (P = .004). Presence of granulation significantly correlated with resection involving anterior commissure (P = .01), > 75%vocal fold length (P = .006), and depth into muscle (P = .001). Delayed healing (>3 months) correlated with T2b tumors (P = .02), depth into ligament (P = .002) and anterior commissure involvement (P = .04). T1a carcinomas more commonly healed in <3 months (P = .005). Many vocal fold wounds heal completely within 3.5 months after angiolytic laser surgery for early glottic carcinoma. Larger and deeper wounds are more likely to heal with granulation tissue. Granulation can resolve without surgical intervention; however, granulation present > 3 months warrants biopsy due to increased risk of malignancy. 4 Laryngoscope, 129:435-440, 2019.

Oncological Outcomes Following Transoral CO2 Laser Microsurgery for T1 Glottic Cancer.

The objective of this study is to analyze oncological outcomes for treatment of Tis and T1 glottic squamous cell carcinoma after transoral laser microsurgery. This study is retrospective analysis of previously untreated, suspected lesion of glottis, staged cT1a and cT1b squamous cell carcinoma in a tertiary care hospital and 53 patients were included in the study. End points for analysis were local control, overall and disease specific survival rates. The local control, ultimate local control with laser alone, 3-year overall survival, 3-year disease specific survival and organ preservation rates were 86.7, 90.5, 92.4, 98.1 and 98.1% respectively. The involvement of anterior commissure did not show any significant impact on local control or survival. TLM is safe and effective treatment of early glottis cancer, associated with less morbidity and a high percentage of local control, survival and organ preservation rates.

Oncologic outcomes of surgical treatment for T3 glottic laryngeal squamous cell carcinoma.

The purpose of this study was to assess the clinical results of patients with T3 glottic laryngeal carcinoma treated with total laryngectomy or partial laryngectomy. We conducted a retrospectively review of 307 patients with T3 glottic laryngeal squamous cell carcinoma (SCC). The 5-year cancer-specific survival (CSS) rate was 71.5% and the overall survival (OS) rate was 70.6%. For patients who underwent total laryngectomy, the 5-year disease-free survival (DFS) rate was 59.8%, and the CSS rate was 67.9%. For partial laryngectomy, the 5-year DFS rate was 64.8%, and the CSS rate was 78.0%. High lymph node and stage status are predictors of mortality for these patients. No difference was found in DFS and CSS rates between patients with negative margins and those with positive margins after postoperative radiotherapy and chemotherapy. Postoperative radiotherapy and chemotherapy are effective treatments for patients with T3 glottic laryngeal carcinoma, especially with a positive margin. For selected patients with T3 glottic laryngeal carcinoma, partial laryngectomy is a good choice because it can achieve satisfactory oncologic results while preserving laryngeal function.

Tumor volume as a predictor of survival in T3 glottic carcinoma: A novel approach to patient selection

BackgroundThe optimal treatment for T3 glottic cancers continues to be debated. Organ preservation has become the standard of care, but not all tumors respond equally. The purpose of this was to investigate the long-term survival outcomes of organ preservation protocols based on tumor volume. MethodsA retrospective review of prospectively collected data from 1966 to 2016 was performed. Patients with T3 vocal cord cancer treated with radiation therapy (RT) at the University of Florida were included. Local control rates as well as survival rates were determined with a Kaplan Meier and Cox regression analysis. Survival was analyzed as a function of tumor volume and an optimal cut point was determined. Results107/234 patients were included. 79% received RT and 21% chemo-RT. 5-year local control was 61.5% and 5-year disease specific survival was 79.3%. Tumor volume was a significant predictor of survival (p = 0.007). An optimal cut point for tumor volume was 2.5 cc. Patients with tumor volumes ≥2.5 cc had significantly worse (p < 0.05) tumor control rates (100% vs. 70.4%). ConclusionTumor volume is a significant predictor of survival outcomes in T3 vocal cord cancers, but will need external validation. Tumors <2.5 cc have favorable outcomes. Those with higher volume tumors should be counselled appropriately and be considered for primary surgical management.

Use of volumetric modulated arc radiotherapy in patients with early stage glottic cancer.

We compared conformal, intensity-modulated radiotherapy (IMRT) and intensity-modulated arc therapy (IMAT) in early stage glottic cancer in terms of dosimetric features as target coverage, dose to the organs at risk and total treatment time. Five consecutive T1 glottic squamous cell carcinoma patients were selected for the study. Three-dimensional conformal radiotherapy (3D-CRT), 3-field or 5-field intensity-modulated radiotherapy (3F-IMRT and 5F-IMRT), or IMAT, which was in 2 different forms--a regular IMAT (R-IMAT) and an alternative IMAT (A-IMAT) with an unirradiated section, was planned for each patient. The prescribed dose was 63 Gy in 28 fractions. The minimum dose for 95% of the clinical target volume (D95), maximum dose point at clinical target volume (Dmax), total monitor units, left and right carotid artery doses (V35 and V50 - percentage of volume receiving 35 Gy and 50 Gy), and total treatment time were calculated for each plan. Median D95 values in the 5 plans studied with each technique ranged between 63 and 63.3 Gy (P = NS). Median Dmax values for each technique ranged between 65.4 and 70.8 Gy. The number of hot spots with IMRT and IMAT was significantly higher than with 3D-CRT plans. Conformal radiotherapy plans median V35 (93.6%) and V50 (76.6-83.3%) values for carotid arteries were significantly higher than with IMRT and IMAT (2.9%-11.4% and 0.0%). Average treatment times for 3D-CRT, 3F-IMRT, 5F-IMRT, R-IMAT and A-IMAT techniques were calculated as 64, 119, 147, 39 and 32 seconds, respectively. IMAT has significantly decreased the treatment time compared to IMRT and 3D-CRT with acceptable homogeneous clinical target volume coverage and low carotid dose.

Study Protocol: Prospective Study of Concurrent Chemoradiotherapy with S-1 and Hypofractionated Radiotherapy for Outpatients with Early Glottic Squamous Cell Carcinomas

Background:The recommended treatment strategies for early glottic carcinoma with intent of larynx preservation are primarily radiotherapy. However, the outcomes of radiotherapy for bulky T1 or T2 glottic carcinoma are unsatisfactory. We designed a protocol consisting of concurrent chemoradiotherapy using S-1 as the radiosensitizer. We have performed this protocol in patients with favorable T2 lesions and demonstrated its efficacy and safety. In contrast, we have treated non-bulky T1 glottic carcinomas with 2.25 Gy per fraction, for a total of 25-28 fractions, starting in 2011 to improve efficacy and shorten the treatment period. Since this treatment strategy was implemented for T1 disease, no local failure has occurred to date, and it appears to be almost as safe as radiotherapy using 2.0 Gy per fraction. With the aim of improving the local control rate and shortening the treatment period primarily for favorable T2 disease, we changed the dose of radiation in our protocol from 2.0 Gy to 2.25 Gy per fraction, for a total of 25 fractions (from 30 fractions). The present study aims to evaluate the efficacy and safety of this new protocol.Methods:This study will be conducted as a clinical, prospective, single-armed, non-randomized trial. Patients are to receive S-1 (55.3 mg /m2 /day, once daily) and radiotherapy (2.25 Gy per fraction, for a total of 25 fractions). S-1 and radiotherapy are started on the same day that radiotherapy is performed, 3-6 hours after oral administration of S-1. The primary study aim is the 3-year local control rate. The secondary study aims are overall survival, voice-preservation survival, disease-free survival, complete response rate, completion rate, and toxicity.Result and conclusion:This is the first single-center, non-randomized, prospective study of concurrent chemoradiotherapy with S-1 and hypofractionated radiotherapy to be conducted. The trial will evaluate the efficacy and safety of our protocol.

Surgical Treatment for Early Stage Glottic Carcinoma with Involvement of the Anterior Commissure.

Objective Assessment of the value of transoral laser microsurgery (TLM) compared with open surgery (OS) for early stage squamous cell carcinoma of the glottic larynx with special regard to involvement of the anterior commissure (AC). Study Design Case series with chart review. Setting Tertiary care otolaryngology clinic. Subjects and Methods Review of clinicopathological data of all patients with previously untreated T1a, T1b, and T2 glottic squamous cell carcinoma of the larynx who were consecutively enrolled over a 10-year period (January 1, 1992, to December 31, 2002). Results Local recurrence rate was 20.4% (10 of 49) for TLM and 10.7% (3 of 28) for OS. Comparison of the TLM and OS groups regarding local recurrence rates revealed a significant difference only for tumors invading the AC ( P = .046). Within the TLM group, tumors with involvement of the AC showed a significantly higher recurrence rate (38.1%; 8 of 21) compared with tumors without involvement of the AC (7.1%; 2 of 28; P = .008). In the OS group, involvement of the AC revealed no significant difference ( P = .45). The overall survival in both groups was comparable in both groups (TLM, 93.9%; OS, 89.3%; P = .47). Conclusion TLM and OS are equally effective surgical treatments for early stage glottic cancer without involvement of the AC, with selection of treatment based on pretreatment endoscopy. However, TLM is associated with less morbidity. In case of invasion of the AC, OS yields lower recurrence rates.

Optimized treatment strategy of radiotherapy for early glottic squamous cell carcinomas: An initial analysis.

ABSTRACTThe purpose of this study was to evaluate the clinical outcomes of radiotherapy for patients with T1/T2 glottic carcinoma. Patients with T1/T2 glottic carcinoma histopathologically diagnosed with squamous cell carcinoma and treated at our hospital between 2007 and 2015 were analyzed retrospectively. Our strategy for T1/T2 glottic carcinoma was as follows: radiotherapy alone with 2.25 Gy per fraction to a total of 25–28 fractions for patients with non-bulky T1 glottic carcinoma; concurrent chemoradiotherapy with oral S-1 and radiotherapy with 2 Gy per fraction to a total of 30 fractions for patients with T1 bulky/T2 favorable glottic carcinoma; or chemoradiotherapy with high-dose cisplatin and radiotherapy with 2 Gy per fraction to a total of 35 fractions for T2 unfavorable glottic carcinoma. Forty-eight patients were eligible. The median follow-up period among surviving patients was 38 months (range, 11–107). The disease was T1a in 23%, T1b in 13%, and T2 in 65% of patients. The 3-year local control rate in all patients, T1a, T1b, and T2 was 96.7%, 100%, 100%, and 96.0%, respectively. Of the 46 patients, one with T2 glottic carcinoma developed recurrent disease at the primary site, and one with T2 glottic carcinoma had lymph node recurrences in the neck. Acute Grade 3 dermatitis occurred in 8 (17%) patients and late Grade 2 hypothyroidism occurred in 2 (4%) patients. This retrospective study shows that our optimized treatment strategy of radiotherapy depending on the stage of early glottic carcinoma is not only effective but also well-tolerated.

Analysis of Recurrence after Frontolateral Laryngectomy.

This study aimed to evaluate the recurrence and survival of patients treated with frontolateral laryngectomy for T1 and T2 glottic laryngeal carcinoma. Patients who underwent frontolateral laryngectomy for glottic laryngeal carcinoma at a tertiary hospital between March 2009 and June 2014 were included. Patient demographics, tumor stage, treatment and histopathological examination data, and adjuvant therapy details were evaluated. Thirty patients with T1aN0, T1bN0, and T2N0 vocal fold carcinoma were examined. The mean follow-up duration was 40 months. Of the 30 patients, nine (30%) were stage T1 and 21 (70%) were in stage T2. Twenty-nine patients were males and one was female, and the mean age was 59 (range, 42-81) years. During follow-up, local recurrence was observed in four patients following frontolateral laryngectomy. Six patients continued smoking after frontolateral laryngectomy, of which three developed tumor recurrence. The local control rate was poor in patients with anterior commissure involvement (66.6%) compared with those with no involvement (95.2%). Two of four patients with local recurrence were treated with salvage total laryngectomy and adjuvant postoperative radiotherapy; the remaining two were treated with only radiotherapy. One patient who was treated with only radiotherapy developed lung metastasis during follow-up and died because of distant metastasis. Frontolateral laryngectomy is an efficient choice of treatment for selected cases of T1 and T2 glottic laryngeal carcinoma.

Relationship of medial versus superior vocal-cord location of T1 squamous cell carcinoma with tumor recurrence

ObjectiveTo determine if the clinical behavior of T1 glottic squamous cell carcinoma varies by its location on the medial free edge or upper aspect of the vocal cords. Study designRetrospective cohort. SettingSingle tertiary university-affiliated medical center. Subjects and methodsClinical, treatment, and outcome data were collected for 104 patients with T1N0M0 glottic squamous cell carcinoma who were treated and followed at our center in 1995–2013. Findings were compared between those with a tumor on the medial (n=60, 57.7%) or superior (n=44, 42.3%) aspect of the cords. ResultsMean follow-up time was 4.15years. No between-group differences were found in demographic or risk factors. There was a significant association of anterior commissure involvement with disease recurrence (P=0.0012) and of superior (vs medial) location with higher rates of anterior commissure involvement (P<0.001) and recurrence (P=0.01) and shorter time to recurrence (P<0.001). ConclusionsT1 squamous cell carcinomas on the superior aspect of the vocal cords have a poorer prognosis than medial tumors and should be closely monitored for recurrence.

Transoral laser microsurgery versus radiotherapy for T2 glottic squamous cell carcinoma: a systematic review of local control outcomes.

Systematic reviews comparing treatment of early glottic cancer with transoral surgery or radiotherapy demonstrate similar oncological outcomes. Most studies of 'early-stage' laryngeal cancer include Tis, T1a, T1b and T2 cases. The data are dominated by patients with T1 and Tis tumours, although extrapolating these results and applying them for T2 cases may be inappropriate. No previous systematic reviews have focused on T2 cancers as a separate group. This review compares local control outcomes for T2 glottic squamous cell carcinoma, treated with transoral microsurgery or external beam radiotherapy. This is a systematic review of case series and comparison studies, focusing on oncological outcomes. Independent searches of MEDLINE, EMBASE and the Cochrane Database were conducted by two authors, using the search terms: laryngeal/glottic/vocal cord combined with carcinoma/cancer/tumour and laser/microsurgery or radiotherapy. Studies of adult patients treated for primary T2N0 glottic squamous cell carcinoma (SCC) with laser surgery or curative radiotherapy were included. Full text of studies satisfying the inclusion criteria were reviewed with extraction of local control and survival data and laryngeal preservation rates. The primary endpoint is local control at 5years. Initial searches identified 3252 studies. Following full-text review of 183 papers, 59 studies met the inclusion criteria, all level IV evidence. A total of 48 studies specified 5-year local control for 1156 patients treated with transoral laser surgery and 3191 patients treated with radiotherapy. Weighted averages of local control at 5years demonstrated similar results: 75.81% for radiotherapy versus 77.26% for transoral laser surgery. The results of this review indicate no difference in 5-year local control between radiotherapy and transoral surgery for T2 glottic SCC. The data demonstrated higher rates of local failure for T2b compared with T2a cases, although outcomes were similar between laser excision and radiotherapy for each substage. Further research focusing upon functional outcomes for T2 glottic tumours is imperative to guide decision-making, ideally with subgroup analysis of T2a and T2b cases.

Oncologic outcomes of patients with positive margins after laser cordectomy for T1 and T2 glottic squamous cell carcinoma.

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. 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. 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). 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.

Prospective analysis of functional swallowing outcome after resection of T2 glottic carcinoma using transoral laser surgery and external vertical hemilaryngectomy.

56 patients affected by T2 glottic carcinoma were treated in two institutes using transoral laser microsurgery (TLM) in 40 cases and vertical hemilaryngectomy in 16 cases between September 2012 and September 2015. In the TLM group, different subtypes of type V cordectomy were used according to the extent of tumor. In the vertical hemilaryngectomy group, classical operation was used in most of the cases and the resection was extended in few cases. Analysis of post-operative swallowing function was done using videofluoroscopy (VFS), functional endoscopic evaluation of swallowing, and subjectively using MD Anderson dysphagia inventory. Objective evaluation of swallowing has been made by obtaining different measures from VFS (pharyngeal transit time, pharyngeal constriction ratio, and hyoid displacement for example). Analysis also included the need and duration of tracheostomy and nasogastric tube, ICU admission, and hospitalization time. Statistical analysis was performed with the Mann-Whitney U and Pearson Chi-square tests. Comparison of incidence of aspiration and swallowing outcome showed significantly better results in the laser group than in the vertical group (p<0.001). The duration of ICU, tracheostomy, nasogastric tube, and hospital stay was also significantly shorter in the laser group (p<0.001). This study shows that TLM had significantly better overall postoperative outcome than vertical hemilaryngectomy. It was associated with significantly shorter hospital stay and less need for tracheostomy, nasogastric tube, and ICU admission). Measures obtained from VFS are useful for detection and follow-up of postoperative aspiration, because it is a definitive technique for anatomical and physiological study of swallowing.

Transoral laser microsurgery as primary treatment for selected T3 glottic and supraglottic cancers

T3 laryngeal cancer encompasses heterogeneous lesions whose treatment is still debated. The purpose of this study was to evaluate transoral laser microsurgery (TLM) in management of selected T3 glottic and supraglottic cancers. Fifty-six patients with selected T3 glottic and supraglottic squamous cell carcinomas (SCCs) treated by TLM ± selective neck dissection ± adjuvant therapy were evaluated in terms of overall survival (OS), disease-free survival (DFS), and organ preservation rates. For the entire cohort, 5-year OS and DFS were 63.3% and 72.4%, whereas they were 65.2% and 72.9% for glottic and 59.3% and 76.3% for supraglottic SCC, respectively. No patient required permanent tracheostomy and 1 patient was gastrostomy tube-dependent at last follow-up. TLM ± selective neck dissection ± adjuvant (chemo)radiotherapy for selected T3 glottic and supraglottic SCC represents an effective alternative treatment to open partial laryngectomies and nonsurgical organ preservation protocols, particularly in elderly and frail patients. © 2016 Wiley Periodicals, Inc.

Transoral robotic surgery for early glottic carcinoma involving anterior commissure: Preliminary reports.

Transoral robotic surgery (TORS) for early glottic cancer has been reported, but the issue of anterior commissure involvement has seldom been addressed. Therefore, the purpose of this study was to preliminarily report the treatment results of TORS in this disease entity. Eight patients with T1 and T2 glottic carcinoma with anterior commissure involvement were selected to receive TORS. The clinical parameters, including rates of adjuvant radiotherapy (RT), survivals, as well as organ and function preservation, were retrospectively analyzed. TORS was successfully performed in all patients without temporary tracheostomy. There were no major complications and no patient received adjuvant RT to the larynx after surgery. With a mean follow-up of 40 months, all patients survived with their larynx preserved and no local recurrence, tracheostomy, or tube feeding dependence. TORS is a feasible approach for selected patients with early T classification glottic carcinoma with anterior commissure involvement. The preliminary oncologic and functional outcomes are satisfactory. © 2015 Wiley Periodicals, Inc. Head Neck 38: 913-918, 2016.

Voice outcome according to surgical extent of transoral laser microsurgery for T1 glottic carcinoma.

To evaluate the outcomes of transoral laser microsurgery (TLM) for T1 glottic carcinoma using longitudinal voice analysis. Retrospective analysis of medical records. We conducted a retrospective review of 57 patients (50 T1a, seven T1b) who underwent TLM for T1 glottic carcinoma, and longitudinal voice analysis was performed before surgery, during the early postoperative period (within 3 months), and during the late postoperative period (more than 6 months). Acoustic, perceptual (Grade, Roughness, Breathiness, Asthenia, Strain scale), and subjective voice analysis using the Voice Handicap Index (VHI) was conducted. Voice quality deteriorated in the early postoperative period in terms of several parameters. However, no significant differences in voice quality were observed in the late postoperative period, whereas Grade (from 1.85 ± 0.83 to 1.50 ± 0.90) and Roughness (from 1.74 ± 0.73 to 1.48 ± 0.87) had improved significantly. Patients who underwent lesser-extent cordectomy (type I, II) showed improvement in VHI-Physical (from 12.93 ± 11.10 to 6.07 ± 8.69) and Grade (from 1.60 ± 0.68 to 0.98 ± 0.83), whereas improvement was not identified in those who underwent larger-extent cordectomy (type III, IV, V). Improvement in Grade (from 1.70 ± 0.80 to 1.23 ± 0.91) and Roughness (from 1.77 ± 0.73 to 1.25 ± 0.76) was identified in patients who had unilateral tumor without involvement of anterior commissure. However, those with involvement of the anterior commissure or bilateral vocal cord showed a tendency toward deterioration in voice quality. Voice quality of patients following TLM for T1 glottic carcinoma may improve significantly over time in cases with lesser-extent types of cordectomy or unilateral tumor without involvement of the anterior commissure. 4 Laryngoscope, 126:2051-2056, 2016.

Intraoral midline mandibulotomy improves laryngeal access for transoral resection of laryngeal cancer

Intraoral midline mandibulotomy is a technique that can be used to increase exposure for transoral endoscopic laser microsurgery (TLS). We describe the case of a 51year old male with persistent T1 glottic carcinoma. At initial diagnosis, he had been referred for curative radiotherapy as laryngeal access was not sufficient for TLS. For treatment of his recurrence, we describe the technique of performing a midline mandibular osteotomy to improve access to the larynx allowing for safe and effective transoral endoscopic laser microsurgery. Surgical access to the larynx was greatly improved, and we were able to perform TLS in a case that would have otherwise not been amenable to TLS. An intraoral midline mandibulotomy can improve access to the larynx and allow for successful transoral resection of laryngeal cancer in patients with otherwise inaccessible tumors.

T1 glottic carcinoma: do comorbidities, facility characteristics, and sociodemographics explain survival differences across treatment?

ObjectiveRecent large-scale studies have observed differences in survival following treatment for early laryngeal carcinoma depending on treatment type but were not able to take sociodemographic, comorbidity, and facility data into account. The objective of this study was to determine whether survival differences across treatment types persist when these factors are included in the analysis.Study DesignRetrospective cohort analysis.SettingLinked Surveillance, Epidemiology, and End Results (SEER)–Medicare data files.Subjects and MethodsMedicare beneficiaries who were identified through the SEER registries (1991-2009) as having T1 glottic squamous cell carcinoma (scca) and a known treatment type were included.ResultsA total of 2338 patients with incident T1 glottic scca were identified. Most were white and male. Treatment type was radiation only in 47%, local surgery and radiation in 39%, and local surgery only in 14%. Black race and increased comorbidities were associated with worse survival. When sociodemographics, comorbidities, and facility characteristics were taken into account, survival differences were observed across treatment types, with those receiving local surgery demonstrating better overall and cancer-specific survival.ConclusionThese results suggest that following treatment of T1 glottic scca, there may be survival differences across treatment types beyond those explained by sociodemographic, comorbidity, and facility characteristics.

Voice and Functional Outcomes of Transoral Laser Microsurgery for Early Glottic Cancer: Ventricular Fold Resection as a Surrogate.

BackgroundThe aim of the study was to evaluate the oncological and functional outcomes with transoral laser microsurgery (TOLM) of patients with early glottic cancer.MethodsWe have prospectively evaluated patients treated with TOLM for Tis, T1 or T2 glottic squamous cell carcinoma. Evaluation of oncological outcomes, and voice and functional outcomes was assessed using voice-handicap index 10 (VHI-10) and performance status scale for head & neck cancer patients (PSS-H&N). Predictors of poor voice quality were evaluated using Student’s t-test.ResultsThirty patients were included, with 17.7 months mean follow-up. There were no cases of locoregional recurrence. Twelve patients (40%) were considered as having a problematic voice outcome. Four subjects out of 30 (13.3%) had significant problems with understandability of speech. Significant differences (P < 0.05) in VHI-10 score were found with tumor stage and partial resection of the ventricular fold.ConclusionsWe report excellent oncological and functional outcomes in early glottic cancer treated with TOLM, with advanced tumors and partial resection of the ventricular fold as a surrogate predicting worse voice outcomes.
