Abstract
Head and neck squamous cell carcinoma (HNSCC), a prevalent and frequently recurring malignancy, often necessitates surgical intervention. The surgical margin (SM) plays a pivotal role in determining the postoperative treatment strategy and prognostic evaluation of HNSCC. Nonetheless, the process of clinical appraisal and assessment of the SMs remains a complex and indeterminate endeavor, thereby leading to potential difficulties for surgeons in defining the extent of resection. In this regard, we undertake a comprehensive review of the suggested surgical distance in varying circumstances, diverse methods of margin evaluation, and the delicate balance that must be maintained between tissue resection and preservation in head and neck surgical procedures. This review is intended to provide surgeons with pragmatic guidance in selecting the most suitable resection techniques, and in improving patients' quality of life by achieving optimal functional and aesthetic restoration.

The impact of margins in laryngeal cancer patients treated with transoral laser microsurgery: a systematic review and meta-analysis. Eur Arch Otorhinolaryngol 2024:10.1007/s00405-024-08610-3. [PMID: 38564009 DOI: 10.1007/s00405-024-08610-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Accepted: 03/11/2024] [Indexed: 04/04/2024]
Abstract
PURPOSE In laryngeal squamous cell carcinoma (LSCC) treated with transoral laser microsurgery (TOLMS), the status of margins significantly affected local control. When a positive or close margin is present, there is no ubiquitous consensus regarding further treatments. The rationale of the present systematic review and meta-analysis is to investigate the survival impact of the status of the margins in patients affected by LSCC treated with TOLMS. DATA SOURCES PubMed, EMBASE, and Cochrane Library. METHODS We performed a systematic search, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria were: patients affected by LSCC, staged according to the American Joint Committee on Cancer Staging System and treated by TOLMS without any previous treatment; margins status (close, positive, negative) and the adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) of overall survival, disease-specific survival, and disease-free survival has to be reported. RESULTS Nine studies were deemed eligible for the qualitative analysis, and 3 for the quantitative analysis to investigate the association between margin status and OS. The cumulative number of patients was 3130. The sample size ranged from 96 to 747 patients. The follow-up period ranged from 0 to 201 months. The meta-analysis results show that positive margins have an aHR of 1.30 yet with CI range (0.56 to 2.97). CONCLUSIONS Our current meta-analysis results are unable to definitively assess the real impact of resection margins on OS. Few authors provide accurate data regarding position and types of margins. Further prospective or high-quality studies are required.

Cantù G. Radical Resection of Malignant Tumors of Major Salivary Glands: Is This Possible? Cancers (Basel) 2024; 16:687. [PMID: 38398078 PMCID: PMC10886922 DOI: 10.3390/cancers16040687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 02/02/2024] [Accepted: 02/05/2024] [Indexed: 02/25/2024] Open
Abstract
In primary therapy, a universally recognized surgical indication applies to all tumors of the salivary glands. According to the classic rule, radical resection of a head and neck tumor requires clean margins of at least 5 mm, although recent studies have shown that for certain locations, 1 mm may be sufficient. In the surgical resection of a tumor of the salivary glands, especially of the parotid gland, can these rules be respected? Owing to the complex branching and connections of the facial nerve within the parotid gland, even a medium-sized malignant tumor may be in contact with a branch of the nerve, thus raising the question of its preservation. The facial nerve is so important from a functional and aesthetic point of view that it is commonly believed that it should be preserved unless it is incorporated into the tumor. This is a compromise between an oncological resection, that is, the complete excision of the tumor with no residual cancer cells left behind, and quality of life. Almost all authors try to overcome this lack of radicality by indicating postoperative (chemo)radiotherapy. In this article, the pros and cons of nerve preservation will be analyzed by examining the published studies on this topic.

Abstract
BACKGROUND The impact of evaluating versus not evaluating surgical margins for early-stage laryngeal squamous cell carcinoma (LSCC) has not been evaluated. METHODS Overall survival was compared between patients who underwent endoscopic surgery for cT1-2, N0, M0 LSCC and had surgical margins evaluated versus not evaluated versus unevaluable in the National Cancer Database (2010-2019) using multivariable-adjusted Cox proportional hazards analyses. RESULTS 7597 patients met study eligibility criteria. 4123 (54.3%) patients underwent margin evaluation, 1631 (21.5%) did not undergo margin evaluation, and 1843 (24.3%) had unevaluable margins. Patients undergoing margin evaluation had better overall survival than patients who did not undergo margin evaluation (HR: 0.88, 95% CI: 0.78-1.00, p = 0.044) and patients with unevaluable margins (HR: 0.88, 95% CI: 0.78-0.98, p = 0.021). Patients undergoing margin evaluation received significantly less adjuvant radiation. CONCLUSIONS Surgical margin evaluation is an important prognostic factor for patients receiving endoscopic surgery for early-stage LSCC and should be conducted whenever possible.

Management and Oncologic Outcomes of Close and Positive Margins after Transoral CO 2 Laser Microsurgery for Early Glottic Carcinoma. Cancers (Basel) 2023; 15:cancers15051490. [PMID: 36900281 PMCID: PMC10000552 DOI: 10.3390/cancers15051490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 02/22/2023] [Accepted: 02/24/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND The present study analyzed the impact of margin status on local control and survival, and the management of close/positive margins after transoral CO2 laser microsurgery for early glottic carcinoma. METHODS 351 patients (328 males, 23 females, mean age 65.6 years) underwent surgery. We identified the following margin statuses: negative, close superficial (CS), close deep (CD), positive single superficial (SS), positive multiple superficial (MS), and positive deep (DEEP). RESULTS A total of 286 patients (81.5%) had negative margins, 23 (6.5%) had close margins (8 CS, 15 CD) and 42 (12%) had positive margins (16 SS, 9 MS, 17 DEEP). Among the 65 patients with close/positive margins, 44 patients underwent enlargement, 6 radiotherapy and 15 follow-up. Twenty-two patients (6.3%) recurred. Patients with DEEP or CD margins showed a higher risk of recurrence (hazard ratios of 2.863 and 2.537, respectively), compared to patients with negative margins. Local control with laser alone, overall laryngeal preservation and disease-specific survival decreased significantly in patients with DEEP margins (57.5%, 86.9% and 92.9%, p < 0.05). CONCLUSIONS Patients with CS or SS margins could be safely submitted to follow-up. In the case of CD and MS margins, any additional treatment should be discussed with the patient. In the case of DEEP margin, additional treatment is always recommended.

Oncological Outcomes of Transoral Laryngeal Microsurgery with Fiber-Optic Diode Laser for Early Glottic Cancer: A Single-Center Experience. Eur Surg Res 2021; 63:132-144. [PMID: 34818662 DOI: 10.1159/000519718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Accepted: 09/16/2021] [Indexed: 12/09/2022]
Abstract
Backgroud/Objectives: Transoral laser laryngeal microsurgery (LTLM) has been widely used in the treatment of early-stage glottic laryngeal squamous cell carcinoma (LSCC) for the past few decades. Although T stage, tumor grade, anterior commissure involvement, type of cordectomy, positive surgical margin, and postoperative additional therapies were accused as the prognostic factors for recurrence, there is still controversy about these data in the literature. The purpose of this study was to evaluate the oncological results of our patients with early glottic LSCC treated with LTLM as a single-modality therapy in a single-center study. METHODS Patients with early-stage (Tis-1-2/N0) glottic LSCC who underwent LTLM as a primary treatment from 2011 to 2019 were retrospectively reviewed. The clinicopathological factors and oncologic outcomes were analyzed. RESULTS One hundred and sixty-one patients were enrolled in this study. The 5-year overall (OS), disease-specific (DSS), disease-free (DFS), and laryngectomy-free survival rates were 84.5%, 97.9%, 79.2%, and 93.5%, respectively. The most common stage, histopathological type, and type of endoscopic cordectomy were T1 stage, well-differentiated cancer, and type 2 cordectomy, respectively. A positive surgical margin was defined in 20 (12.4%) patients. There was a significant relationship between histopathological grade and positive surgical margins (p = 0.038). OS and DSS rates of "wait and see" modality were lower, while DFS of radiotherapy was lower than that of other treatment modalities in patients with positive surgical margins, but the differences were not statistically significant. Nineteen (11.8%) patients had a recurrence. DSS was statistically significantly lower in patients with recurrence (p < 0.001). CONCLUSION The results of our study showed that anterior commissure involvement, surgical margin positivity, and higher T stage statistically did not reduce survival rates in early-stage LSCC patients treated with LTLM. As the histopathological grade of the tumor worsens, the risk of surgical margin positivity increases. RT may have a negative effect on recurrence and organ preservation in the additional treatment of patient with positive surgical margins.

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
BACKGROUND Management of early stage glottic carcinoma involving the anterior commissure is challenging. AIMS/OBJECTIVES This study aimed to evaluate the efficacy of a thyroid cartilage window (TCW) technique for transoral laser resection of early glottic cancer with involvement of the anterior commissure. MATERIAL AND METHODS Twenty-one patient who underwent a TCW technique for transoral resection early glottic carcinoma involving the anterior commissure, were retrospectively analyzed. The technical nuances, organ preservation rate and voice outcomes, local and regional recurrence, and perioperative comorbidities, were assessed. RESULTS All 21 patients underwent a TCW technique for resection, both the organ preservation rate and negative margin achieved 100%. The local control rate achieved 100%, and the 5 years recurrence free survival was 90.5%. For two patients with subglottic involvement (9.5%), regional recurrence with confirmation of a positive pre-laryngeal lymph node was observed. Postoperative granuloma was detected in all 21 patients, 13 of whom spontaneously disappeared (61.9%); whereas the remaining 8 patients (38.1%) demonstrated a consistent presence of granuloma more than 12 weeks, and they accepted surgical extirpation of granuloma under surface anesthesia. The laryngeal web developed in all 21 patients, while no dyspnea and local recurrence were present. By comparison with preoperative baseline, postoperative self-assessment voice demonstrated a significant improvement (p = .01), while objective voice indices were not significantly altered (p > .05). CONCLUSIONS AND SIGNIFICANCE TCW technique is a valuable means for transoral resection of early glottic laryngeal cancer involving the anterior commissure, with acceptable voice quality and seemingly low comorbidities.

Shrinkage of specimens after CO 2 laser cordectomy: an objective intraoperative evaluation. Eur Arch Otorhinolaryngol 2021; 278:1515-1521.

Abstract
PURPOSE The margin status after CO2 laser cordectomy for glottic carcinoma may influence prognosis. There are no studies assessing the possible bias due to anatomic changes of the specimens for shrinkage. The authors evaluated the intraoperative shrinkage of specimens immediately after transoral CO2 laser microsurgery (CO2 TOLMS) to improve the understanding and the interpretation of surgical margins. METHODS This is a prospective study involving a consecutive cohort of 23 patients (19 males, 4 females, mean age 69.9 years, range 42-83 years) with early glottic carcinoma treated by CO2 TOLMS from February 2017 to April 2019. The anteroposterior shrinkage of the specimen, of the tumor, and of the anterior and posterior margins was measured intraoperatively with a cross table reticle glass micrometer ruler, inserted into the eyepiece of the surgical microscope. RESULTS The mean shrinkage of the mucosal specimen from intralaryngeal measurement to post-resection measurement was 3.8 ± 0.3 mm, resulting in an average loss of 29% of the anteroposterior length (p < 0.01). The anteroposterior length of both the tumor and the margins after resection significantly decreased, but the shrinkage of the anterior and posterior margins was significantly greater than the shrinkage of the tumor (49% versus 20% and 45% versus 20%, p < 0.01). CONCLUSION The present study demonstrates significant shrinkage of specimens after CO2 TOLMS, especially in the anteroposterior length of the vocal cords, and justifies the good oncological results for specimens with close and single positive superficial margins. Follow-up versus a second surgical look policy could be safely suggested in cases of close superficial and single positive superficial margins.

Braz J Otorhinolaryngol 2020; 88:669-674. [PMID: 33272837 PMCID: PMC9483927 DOI: 10.1016/j.bjorl.2020.09.008] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 09/03/2020] [Accepted: 09/14/2020] [Indexed: 01/12/2023] Open
Abstract
Introduction Transoral laser microsurgery represents the treatment of choice for early glottic cancer. Its use and effectiveness are mainly related to laryngeal exposure and deep extension of tumor. Histopathologic assessment of surgical margin presents a main issue about transoral laser microsurgery and complete oncological excision. Objective The aim was to analyze the impact of revision surgery on organ preservation and local disease control in patients with early glottic cancer treated by transoral laser microsurgery. Methods We carried out a retrospective study on a cohort of 153 patients with early glottic cancer (Tis, T1, T2) treated by transoral laser microsurgery. Resection margins were classified as follows: “free” if macroscopic margin-tumor distance was at least 2 mm, as “close” if it was less than 2 mm and “positive” if the margin was involved by carcinoma. Patients were divided into two groups: patients with free resection margins (Group A) and patients with positive, close or not-evaluable resection margins (Group B). Group A (36) underwent periodic followup. Group B (117) underwent a second look laser CO2 2 months after surgery. Fifteen patients of Group A with suspected persistence of carcinoma during followup underwent a second laser resection after a time interval of 4–8 months after first surgery. Overall survival, disease-free survival, disease-specific survival, ultimate local control with laser alone and organ preservation rates were estimated. Results Five-year overall survival rate and 5-year disease-specific survival were 100% in both groups. The five-year laryngeal preservation rate was 100% in Group A and 95.2% in Group B. Five-year disease-free survival was 92.15% and 5-year ultimate local control with laser alone in 92.15% of patients. Conclusion This study has demonstrated that revision Transoral Laser Microsurgery is able to confirm the oncological radicality in most cases, even in the case of positive, close or non-evaluable margins. Considering our results, according to our experience, the second look with CO2 laser is a therapeutic strategy to consider, even in the case of close or non-evaluable as well as positive margins.

Early Glottic Cancer Treated by Transoral Laser Surgery Using Toluidine Blue for the Definition of the Surgical Margins: A Pilot Study. ACTA ACUST UNITED AC 2020; 56:medicina56070334. [PMID: 32635245 PMCID: PMC7404472 DOI: 10.3390/medicina56070334] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 06/29/2020] [Accepted: 06/30/2020] [Indexed: 11/25/2022]
Abstract
Background and objectives: Transoral laser microsurgery (TLM) is widely accepted for its advantages, which consist of a brief hospital stay, rapid functional recovery, low management costs and the fact that it can be easily repeated in cases of recurrence. However, a high incidence of positive or narrow surgical margins has been reported in the literature, even if controversy still exists on the prognostic significance of positive resection margins. The aim of the study was to evaluate the utility of toluidine blue staining in defining the resection margins of early glottic cancer (T1a–T2) treated with TLM. Materials and Methods: This retrospective study was conducted on patients with early glottic cancer (T1a–T2) managed by TLM. A group of patients treated between 2010 and 2014 underwent toluidine blue staining (TB group) of the lesions before starting the cordectomy by TLM, and a group of patients treated by TLM between 2006 and 2009 was considered the control group. Results: A total of 44 subjects were included in this study: 41 were men, and 3 were women. The mean age was 58 ± 9.0 years (median 59.0, range 41–77). Twenty-three of the 44 patients were included in the TB group and 21 in the case control group. In the TB group, only the positivity of the deep margin was a predictor of local recurrence (p = 0.037), while in the control group, positive or close margins and the type of cordectomy were predictive factors of local recurrence (p = 0.049). Considering the TB group and control cases, the 5-year local recurrence-free survival was 95.6% and 80.9%, respectively (p = 0.14). Conclusions: From this first study, toluidine blue staining seems to be a useful modality to improve the rate of the negative resection margins of early glottic cancer (T1a–T2) treated by TLM.

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).
