Targeting Anterior Commissure Involvement with Hyperfractionated Radiotherapy for T1-T2 Squamous Cell Carcinoma of the Glottic Larynx. Cancers (Basel) 2024; 16:1850. [PMID: 38791929 PMCID: PMC11119720 DOI: 10.3390/cancers16101850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 04/25/2024] [Accepted: 05/10/2024] [Indexed: 05/26/2024] Open
Abstract
Anterior commissure is involved in about 20% of early-stage glottic squamous cell carcinomas (EGSCCs). Treatment outcomes and prognostic factors for EGSCC with anterior commissure involvement (ACI) were evaluated by focusing on hyperfractionated radiotherapy (74.4 Gy in 62 fractions). One-hundred and fifty-three patients with T1-T2 EGSCC were included in this study. The median total doses for T1a, T1b, and T2 were 66, 74.4, and 74.4 Gy, respectively. Overall, 49 (32%) patients had T1a, 38 (25%) had T1b, and 66 (43%) had T2 disease. The median treatment duration was 46 days. The median follow-up duration was 5.1 years. The 10-year overall and cause-specific survival rates were 72% and 97%, respectively. The 10-year local control rates were 94% for T1a, 88% for T1b, and 81% for T2 disease. Local control rates in patients with ACI were slightly better than those in patients without ACI with T1a and T1b diseases; however, the difference was not significant. The 10-year laryngeal preservation rate was 96%. Six patients experienced grade 3 mucositis, and four patients had grade 3 dermatitis. Hyperfractionated radiotherapy was effective for T1 disease with ACI, but insufficient for T2 disease with ACI. Our treatment strategy resulted in excellent laryngeal preservation.

Abstract
Oblique orientation of vocal cord demands strict compliance, by technicians and clinicians, to the recommended parallel plane CT scan of larynx. Repercussions of non-compliance has never been investigated before. We aimed to observe influence of non-parallel vocal cord plane CT scan on qualitative and quantitative glottic parameters, keeping parallel plane CT as a standard for comparison. Simultaneous identification of potential suboptimal imaging sequelae as a result of unformatted CT plane was also identified. In this study we included 95 normal adult glottides and retrospectively analyzed their anatomy in two axial planes, non-parallel plane ① and parallel to vocal cord plane ②. Qualitative (shape, structures at glottic level) and quantitative (anterior commissure ACom, vocal cord width VCw, anteroposterior AP, transverse Tr, cross-sectional area CSA) glottic variables were recorded. Multivariate statistical analysis was used to predict pattern and their impact on glottic anatomy. Plane ① displayed supraglottic features in glottis; adipose (90.5%) and split thyroid laminae (70.6%). Other categorical variables: atypical shape, submental structures and multilevel vertebral crossing were also in majority. All glottic dimensions varied significantly between two planes with most in ACom (-5.8mm) and CSA (-15.0 mm2). In contrast, plane ② manifested higher VCw (>73%), Tr (66.3%), CSA (64.2%) and AP (44.2%) measurements. On correlation analysis, variation in ACom, CSA, Tr was positively associated with VC or plane obliquity (p<0.05). This variability was more in obese and short necked subjects. Change in one parameter also modified other significantly i.e., ACom versus AP and CSA versus Tr. Results indicated statistically significant change in subjective and objective anatomical parameters of glottis on non-application of appropriate CT larynx protocol for image analysis hence highlighting importance of image reformation.

Abstract
Objectives Glottic tumors with infiltration of the anterior/posterior commissure, and lesions with subglottic, cricoid, or cricoarytenoid joint infiltration have been highly controversial in the past, from the perspective of oncological safety. Although conservation laryngeal resection options exist, most are limited by the extent of resection proscribed by the technique and the postoperative functional results. Oncologically speaking, extended vertical hemilaryngectomy is often the optimal solution. However, limited reconstruction methods often compel total laryngectomy. Methods Eight patients with vocal fold malignancy, which infiltrated the anterior and sometimes the posterior commissure and with subglottic extension and resultant uni/bilateral vocal fold motion impairment, were treated by single stage extended vertical partial laryngectomy with rotational crico-thyrotracheopexy as a functional reconstruction of the laryngeal framework. Patients were evaluated with objective and subjective function tests. Results Histologic examination demonstrated tumor-free margins in every case. Definitive decannulation was successful in all cases within 2 weeks. All patients had a stable and adequate airway during follow-up and reported socially acceptable voice. Oral feeding was possible in seven patients. Conclusion Rotational crico-thyrotracheopexy, as a single stage reconstruction technique, is based on well-vascularized, readily available, appropriately shaped local tissues, without significant donor site morbidity or need for long-term stenting to reconstruct large laryngeal defects after extended vertical hemilaryngectomy for advanced unilateral glottic tumors and is applicable even with supra/subglottic invasion or infiltration of the contralateral vocal fold. An adequate airway can be achieved with socially acceptable voice and safe swallowing without compromising oncologic reliability. Level of Evidence 4 (retrospective case series review).

Abstract
OBJECTIVES Preoperative anterior commissure (AC) evaluation in glottic cancer is crucial for therapeutic decisions. Endoscopy is often inadequate to precisely detect the presence of cancer in the AC; thus, computed tomography (CT) scan could help. We investigated the relation between AC thickness on CT scan (in mm), AC involvement by cancer at histology, and radiologic signs of anterior paraglottic space (PGS) infiltration. STUDY DESIGN Retrospective observational study. METHODS An experienced radiologist retrospectively measured AC thickness and identified signs of anterior PGS infiltration on pretreatment contrast-enhanced CT scans of 80 patients with primary glottic cancer. The gold standard to define the presence of cancer in the AC was histology. The receiver operating characteristic (ROC) curves were used to determine the potential cut-off values of AC thickness (Youden index method) able to maximize both sensitivity and specificity in identifying the presence of cancer in the AC at histology and PGS infiltration on CT scan. RESULTS AC was significantly thicker in patients with cancer in the AC at histology (P < .001) and in patients with PGS infiltration on CT scan (P < .001). The cut-off values to discriminate the presence of cancer at histology and PGS infiltration on CT scan were 3.62 and 2.6 mm, respectively. We found a substantial agreement between anterior PGS infiltration on CT scan and the presence of cancer in the AC at histology (Cohen Kappa: P = .70). CONCLUSION AC thickness and radiologic signs of PGS infiltration on pretreatment CT scan could represent a method to predict the presence of cancer in the AC at histology.

Abstract
Introduction Discerning the preoperative nature of vocal fold leukoplakia (VFL) with a substantial degree of certainty is fundamental, seeing that the histological diagnosis of VFL includes a wide spectrum of pathology and there is no consensus on an appropriate treatment strategy or frequency of surveillance. The goal of our study was to establish a clear schedule of the diagnostics and decision-making in which the timing and necessity of surgical intervention are crucial to not miss this cancer hidden underneath the white plaque. Material and Methods We define a schedule as a combination of procedures (white light and Narrow Band Imaging diagnostic tools), methods of evaluating the results (a combination of multiple image classifications in white light and Narrow Band Imaging), and taking into account patient-related risk factors, precise lesion location, and morphology. A total number of 259 patients with 296 vocal folds affected by leukoplakia were enrolled in the study. All patients were assessed for three classifications, in detail according to Ni 2019 and ELS 2015 for Narrow Band Imaging and according to Chen 2019 for white light. In 41 of the 296 folds (13.9%), the VFL specimens in the final histology revealed invasive cancer. We compared the results from the classifications to the final histology results. Results The results showed that the classifications and evaluations of the involvement of anterior commissure improve the clinical utility of these classifications and showed improved diagnostic performance. The AUC of this model was the highest (0.973) with the highest sensitivity, specificity, PPV, and NPV (90.2%, 89%, 56.9%, and 98.3%, respectively). Conclusion The schedule that combines white light and Narrow Band Imaging, with a combination of the two classifications, improves the specificity and predictive value, especially of anterior commissure involvement.

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.

T1 Glottic Cancer: Does Anterior Commissure Involvement Worsen Prognosis? Cancers (Basel) 2020; 12:cancers12061485.

Abstract
Radiotherapy (RT) and transoral laser microsurgery (TLM) represent the main treatment modalities for early glottic carcinoma. Local failure is notoriously more frequent in T1b glottic cancer in comparison to T1a and T2 tumors. In this scenario, the role of anterior commissure (AC) involvement is still controversial. The aim of the present study was therefore to determine its potential prognostic power in worsening patients’ survival and outcomes. We categorized different tumor glottic fold locations with respect to the involvement of one (T1a) or both vocal cords, with or without AC involvement. We analyzed a retrospective cohort of 74 patients affected by Stage I glottic cancer, treated between 2011 and 2018 by TLM or RT at a single academic institution. There were 22 T1a (30%) and 52 T1b (70%) cases. The median follow-up period was 30 months (mean, 32.09 ± 18.738 months; range, 12–79). Three-year overall survival (OS), disease-specific survival (DSS), recurrence-free survival (RFS), and laryngectomy-free survival (LFS) were compared according to tumor location, extension, and cT category. According to both uni- and multivariate analyses, an increased risk for recurrence in T1b with AC involvement and T1a tumors was 7.31 and 9.45 times, respectively (p-values of 0.054 and 0.030, respectively). Among the 17 recurrences, T1b with AC involvement experienced 15 tumor relapses (88.2%), thus significantly affecting both the RFS and LFS in comparison to the other two tumor subcategories (T1a, p = 0.028 and T1b without AC involvement, p = 0.043). The deteriorating prognosis in the presence of AC involvement likely reflects the need to power the hazard consistency and discrimination of the T1b category when associated with such a risk factor, thus deserving an independent T category.

Abstract
MATERIALS AND METHODS The records of patients treated with TLM with previously untreated early stage glottic squamous cell carcinoma were reviewed. RESULTS A total of 201 patients were enrolled: 191 men (95.0%) and 10 women (4.98%). The anterior commissure (AC) was involved in 94 (47.8%) patients. The 3- and 5-year overall survival rates of all patients were 94.5% and 90.9%. The local recurrence rates were 30.8% in the AC involvement (AC+) group and 16.0% in the group without AC involvement (AC-). The mortality rates were 18.1% and 3.7% in the AC+ and AC- groups. The 3- and 5-year disease-free survival rates were lower in the AC+ group (89.1%, 82.5%) than that in AC- group (99.0%, 96.5%). Local recurrence rates were 25%, 22.7%, 23.4%, and 22.1% for Tis, T1a, T1b, and T2 lesions. The mortality rates were 0.0%, 4.6%, 12.8%, and 15.3%. Three- and 5-year disease-free survival rates did not differ significantly between the tumor stage subgroups. The mortality for patients with local recurrence was 22.2%, which was higher than that for those without recurrence. The organ preservation rate was 98.5%. PURPOSE This study was to assess the rates of oncological outcomes in patients with early stage glottic squamous cell carcinoma treated with transoral laser microsurgery (TLM). CONCLUSION AC involvement was a predictor of local recurrence, and its presence was associated with a reduced survival rate and increased mortality after TLM. TLM got high survival rate and low recurrence rate. The staging and oncological outcomes did not differ between tumor stage subgroups.

[PMID: 31721216 DOI: 10.1002/lary.28395] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 09/29/2019] [Accepted: 10/10/2019] [Indexed: 12/19/2022]
Abstract
OBJECTIVE The anterior commissure is considered a laryngeal subsite, but it is not taken into account in the current T-staging system. The impact of anterior commissure involvement (ACI) on the oncologic outcomes of T1 glottic tumors has not been well defined and remains controversial. The aim of this study was to assess the influence of ACI in the prognosis of T1 glottic tumors. METHODS A systematic review and meta-analysis of observational studies was performed by including studies published up to July 2019. Studies were selected if they had investigated the local control rate (LCR) at 5 years of clinical stage I (T1 and N0) glottic squamous cell carcinoma with and without ACI. The difference in LCR at 5 years between T1 glottic tumors without and with ACI was evaluated. RESULTS The meta-analysis showed that the difference in LCR at 5 years between T1 glottic tumors without and with ACI is 12% (95% confidence interval: 8%-16%, p < 0,0001, I2 = 34.81%). CONCLUSIONS Our study pointed out that the anterior commissure involvement is a negative prognostic factor in LCR at 5 years for T1 glottic tumors. Our results suggest the need to consider ACI in the T staging of glottic tumors. Laryngoscope, 130:1932-1940, 2020.

Involvement of the Anterior Commissure in Early Glottic Cancer (Tis-T2): A Review of the Literature. Cancers (Basel) 2019; 11:cancers11091234. [PMID: 31450795 PMCID: PMC6769981 DOI: 10.3390/cancers11091234] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2019] [Revised: 08/19/2019] [Accepted: 08/20/2019] [Indexed: 12/17/2022] Open
Abstract
Background: The impact of the anterior commissure (AC) involvement on prognosis in laryngeal cancer remains a topic of discussion with inconsistent results in the literature. This review examines AC involvement as a prognostic factor in patients with early glottic cancer (Tis-T2) treated with radiotherapy or transoral laser microsurgery (TLM). Methods: A systematic literature search was performed. Due to the heterogeneity of the data, no meta-analysis was implemented. Weighted averages were calculated if the appropriate data were extractable. Results: Thirty-four studies on radiotherapy and 23 on TLM fit the inclusion criteria. The majority of studies for both radiotherapy (67.7%) and TLM (75.0%) did not report a significant impact on oncological outcomes. Weighted averages were slightly lower in patients with AC involvement. The two studies that applied a more detailed classification showed a significant impact on the amount of AC involvement. Conclusions: Binary variables (yes/no) for AC involvement lead to inconsistent results. Studies that use more detailed classifications of the AC show that there is a significant impact on the outcome. To further elucidate the role of the AC, detailed stratification of tumors involving the AC need to be investigated in further studies for both treatment modalities.

Abstract
BACKGROUND AND OBJECTIVES Controversial prognostic factors of primary CO2 laser cordectomy are anterior commissure involvement (ACI) and status of margin. STUDY DESIGN/MATERIALS AND METHODS Retrospective analysis of oncological outcomes in 102 patients with early glottic cancer undergoing laser cordectomy between 2013 and 2015. RESULTS The T stages distribution included: 72.6% T1a, 14.7% T1b, and 12.7% T2. The ACI was diagnosed in 26 patients. The primary cordectomy was radical in 72 patients. The 2- and 5-year disease free survival (DFS) for all patients were, respectively, 83.3% and 77.3%.The 2-year DFS rates for T1a, T1b, T2 were, respectively, 91.7%, 66.7%, and 53.9% and the differences were statistically significant (P < 0.001). The 2-year DFS rates according to the ACI and free anterior commissure tumors were, respectively, 65.4% and 89.2%, and the ACI indicated worse prognosis (P = 0.057). The 2-year DFS rates according to margins status were higher for patients with close or positive margins, who had second resection (88.9%) compared with those of negative margins (80.9%) (P = 0.340).

Arch of cricoid cartilage anatomical variation: morphological and radiological aspects. Surg Radiol Anat 2019; 41:539-542.

Abstract
The cricoid cartilage serves as an anatomical reference for several surgical procedures for access to the airway. Additionally, it serves as an attachment point for muscles that move the vocal folds. We present a case where the cricoid cartilage arch is divided into distinct superior and inferior arches, with a fibrous membrane between them. We did not find any similar description to this case in the literature, which makes it unique to date. This type of variation is important knowledge for clinicians and surgeons during airway management in the anterior neck region. The presence of this variation could induce an error during a palpation of the thyroid and cricoid cartilages, realized in clinical examination and surgical or emergency procedures.
