Laryngoscope 2024; 134:3003-3011. [PMID: 38251796 DOI: 10.1002/lary.31273] [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: 07/24/2023] [Revised: 12/09/2023] [Accepted: 12/27/2023] [Indexed: 01/23/2024]
Abstract
OBJECTIVE The primary objective of this study was to evaluate oncologic outcomes of all published cases of supracricoid partial laryngectomy (SCPL) performed in the United States. The secondary objective was to assess the functional outcomes associated with this procedure. REVIEW METHODS A systematic review of PubMed, SCOPUS, and Embase for all English-language studies pertaining to SCPL performed in the United States was conducted until August 2021. Primary outcomes included disease-specific survival (DSS), overall survival, and local recurrence rate. Secondary outcomes included larynx preservation rate, gastrostromy tube dependency, days to gastrostomy tube removal, decannulation rate, and days to decannulation. RESULTS A total of six studies were included in the analysis. A total of 113 patients (58.5%) underwent SCPL surgery as a primary treatment method whereas 80 patients (41.5%) underwent SCPL as salvage surgery. The 5-year DSS rates were 87.8% and 100% for primary and salvage procedures, respectively. Approximately 10.3% of patients undergoing a salvage SCPL procedure experienced a local recurrence whereas only 1.85% of primary SCPL procedures resulted in local recurrence. The rates of decannulation following primary and salvage SCPL were 92.7% and 88.1%, respectively. With regard to swallowing, primary and salvage SCPL procedures demonstrated comparably low postoperative gastrostomy tube dependency rates of 3.66% and 4.76%, respectively. CONCLUSIONS SCPL performed in the United States is an effective surgical technique that produces excellent outcomes in qualifying patients, thus validating its viability as an organ-preserving surgical alternative.

Abstract
OBJECTIVE This study evaluated the swallowing and voice function of laryngeal cancer patients after Supracricoid Partial Laryngectomy(SCPL), and its influence on quality of life to provide a reference for the selection of surgical methods for laryngeal cancer patients. METHODS Twenty-one patients who received SCPL between April 2015 and November 2021 were included. Each patient's swallowing function and quality of life were assessed through fiberoptic endoscopic examination of swallowing (FEES) and the M.D. Anderson Dysphagia Inventory (MDADI). Fundamental, jitter, shimmer, maximum phonation time (MPT), and voice handicap index-10 (VHI-10) were performed to assess voice function and voice-related quality of life. RESULTS The results of the FEES of the 21 patients were as follows: the rates of pharyngeal residue after swallowing solid, semiliquid, and liquid food were 0%, 28.57%, and 38.09%, respectively; the rates of laryngeal infiltration after swallowing solid, semiliquid, and liquid food were 0%, 28.57%, and 4.76%, respectively; and aspiration did not occur in any of the patients. In the evaluation of swallowing quality of life, the mean total MDADI score was 92.6 ± 6.32. The voice function evaluation showed that the mean F0, jitter, shimmer, and MPT values were 156.01 ± 120.87 (HZ), 11.57 ± 6.21 (%), 35.37 ± 14.16 (%) and 7.85 ± 6.08 (s), respectively. The mean total VHI-10 score was 7.14 ± 4.84. CONCLUSION SCPL provides patients with satisfactory swallowing and voice function. The patients in this study were satisfied with their quality of life in terms of swallowing and voice. SCPL can be used as a surgical method to preserve laryngeal function in patients with laryngeal cancer.

Abstract
OBJECTIVE To investigate the possible causes and treatment methods of laryngeal stenosis after radiotherapy following supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCPL-CHEP). METHODS The data of seven patients with laryngeal stenosis after radiotherapy following SCPL-CHEP were analysed retrospectively. All patients were diagnosed with mid-stage or advanced laryngeal carcinoma before surgery, and the pathological type was squamous cell carcinoma. All patients met the requirements for SCPL-CHEP surgery. When laryngeal stenosis was found during the post-surgical follow-up period, patients were immediately given the appropriate treatment according to their conditions. RESULTS All seven patients had laryngeal stenosis. One patient underwent granulation resection using a laryngoscope, four patients underwent granulation removal + low-temperature plasma ablation using a laryngoscope, and two patients underwent laryngeal dehiscence surgery + laryngotracheal T-tube placement. All patients recovered well after surgery, with patent airways. CONCLUSION Laryngeal stenosis in patients with mid- and late-stage laryngeal carcinoma is one of the rare complications of SCPL-CHEP. Second-stage laryngeal dilatation can be selected according to the patient's laryngeal stenosis. Most patients with laryngeal stenosis can be extubated completely.

Head Neck 2023; 45:243-250. [PMID: 36177857 DOI: 10.1002/hed.27205] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 06/26/2022] [Accepted: 09/06/2022] [Indexed: 12/14/2022] Open
Abstract
The first aim was to define the oncologic outcomes of open partial laryngectomy (OPL) in naïve pT3 laryngeal cancer. The second aim was to analyze the outcomes after OPL versus total laryngectomy (TL). A literature search was conducted in three databases (MEDLINE, EMBASE, and Cochrane Library) until January 2022. In 805 patients treated with OPL, 5-year OS, DSS, DFS and LFS were 80.5% (95% CI 70.6-87.6), 83.4% (95% CI 75.7-89), 77.4% (95% CI 66.3-85.7) and 77.9% (95% CI 68.7-85), respectively. Three articles compared TL versus OLP: 5-year OS, DSS and DFS risk difference were 0.100 (95% CI -0.092 to 0.291), 0.067 (95% CI -0.085 to 0.220) and 0.018 (95% CI -0.164 to 0.201) respectively. OPL for selected pT3 laryngeal cancer is able to guarantee a high percentage of oncological success. Accurate patient selection is of utmost importance to differentiate advanced disease amenable to conservative surgery.

Abstract
Background: Open partial horizontal laryngectomy type II (OPHL type II) has two main aims: oncological radicality and laryngeal preservation. The aim of this review is to define and emphasize the oncological efficacy of OPHL type II, both as primary and salvage surgery, by analyzing the latest literature. Methods: The research was carried out on Pubmed, Scopus and Web of Science databases, by using strict keywords. Oncological outcomes were evaluated by the following parameters: overall survival, disease-specific survival, disease-free survival, local control, laryngeal preservation, local recurrence. Results: The review included 19 articles divided into three groups: (1) primary OPHL type II, (2) salvage OPHL type II, (3) adjuvant radiotherapy after primary OPHL type II. The articles showed excellent results as far as oncological radicality and organ preservation. Conclusions: This review demonstrated that OPHL type II is useful to obtain oncological radicality both as primary surgery and salvage surgery. Nevertheless, the only criterion that determined the positive outcome and efficacy of this technique is the strict selection of patient and tumor.

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
PURPOSE OF REVIEW The objective of this review article is to discuss the current role of surgery as the primary treatment modality in patients with head and neck squamous cell carcinoma (HNSCC). RECENT FINDINGS HNSCC represents one of the cancer locations where the primary treatment modality is the most under discussion. Indeed, the respective roles of primary surgical resection followed, as necessary, by adjuvant radiotherapy or definitive chemoradiotherapy remain controversial. The results of organ preservation trials and the drastic rise in the incidence of human papillomavirus-induced oropharyngeal tumors, which are known to be highly radiosensitive, have led to an increasing use of chemoradiation-based therapies in HNSCC patients. However, no chemoradiation-based protocol has shown better oncologic outcomes than radical primary surgery. Moreover, development of minimally invasive surgical techniques, such as transoral robotic surgery, and advances in head and neck microvascular reconstruction have considerably improved the clinical outcomes of the patients and have led to a reconsideration of the role of primary surgery in HNSCC patients. SUMMARY Surgery should be the primary treatment modality for most resectable oral cavity cancers and for T4a laryngeal/hypopharyngeal cancers. Primary surgery could also be the preferred modality of treatment for most early (T1-T2, N0) laryngeal and hypo/oropharyngeal carcinomas when this strategy offers an opportunity to reserve radiotherapy for a potential recurrence or second primary tumor. Primary surgery should also be considered in patients with locally advanced human papillomavirus-negative oropharyngeal carcinoma.

Abstract
In this article, we aimed to discuss the role of total laryngectomy (TL) in the management of patients with larynx cancer (LC) in the era of organ preservation. Before the 1990s, TL followed by radiotherapy (RT) was the standard treatment for patients with locally advanced LC. Over the last 30 years, various types of larynx preservation (LP) programs associating induction or concurrent chemotherapy (CT) with RT have been developed, with the aim of treating locally advanced LC patients while preserving the larynx and its functions. Overall, more than two-thirds of patients included in a LP program will not require total laryngectomy (TL) and will preserve a functional larynx. However, despite these advances, the larynx is the only tumor site in the upper aero-digestive tract for which prognosis has not improved during recent decades. Indeed, none of these LP protocols have shown any survival advantage compared to primary radical surgery, and it appears that certain LC patients do not benefit from an LP program. This is the case for patients with T4a LC (extra-laryngeal tumor extension through the thyroid cartilage) or with poor pretreatment laryngeal function and for whom primary TL is still the preferred therapeutic option. Moreover, TL is the standard salvage therapy for patients with recurrent tumor after an LP protocol.

Abstract
BACKGROUND Open partial laryngeal surgery (OPLS) represents a wide array of procedures that can be fitted to treat different types of laryngeal cancer (LC). We would like to present our 30-years' institutional experience, to analyze survival outcomes and to critically discuss prognostic factors. METHODS We reviewed all cases of OPLS performed at our Institution from 1982 to 2016 for LC. Survival analysis by Kaplan-Meier estimate was performed and prognostic variables by multivariate analysis were identified. RESULTS Mean follow-up time was 68.3 months, 30-day mortality 0.2%, subsequent functional total laryngectomy (TL) was 1.01%. Over 80% of cases were stage I to II. We had 25 local, 62 regional and eight distant recurrences. Local control was 94.9%, overall survival (OS) was 83.4% and disease-specific survival (DSS) was 87.7%. The two major risk factors significantly associated with the risk of death were cT and cN stage. CONCLUSIONS: We have confirmed that OPLS represents an oncologically sound option in the treatment of LC despite the emergence of non-surgical strategies and new transoral mininvasive techniques. Our results highlight that accurate staging, correct selection of the patient and a strong surgical expertise are of paramount importance in this type of surgery.

Open Partial Horizontal Laryngectomies for T3⁻T4 Laryngeal Cancer: Prognostic Impact of Anterior vs. Posterior Laryngeal Compartmentalization. Cancers (Basel) 2019; 11:cancers11030289. [PMID: 30832209 PMCID: PMC6468624 DOI: 10.3390/cancers11030289] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2019] [Revised: 02/23/2019] [Accepted: 02/24/2019] [Indexed: 01/16/2023] Open
Abstract
Open partial horizontal laryngectomies (OPHLs) are well-established and oncologically safe procedures for intermediate–advanced laryngeal cancers (LC). T–N categories are well-known prognosticators: herein we tested if “anterior” vs. “posterior” tumor location (as defined in respect to the paraglottic space divided according to a plane passing through the arytenoid vocal process, perpendicular to the ipsilateral thyroid lamina) may represent an additional prognostic factor. We analyzed a retrospective cohort of 85 T3–4a glottic LCs, treated by Type II or III OPHL (according to the European Laryngological Society classification) from 2005 to 2017 at two academic institutions. Five-year overall survival (OS), disease-specific survivals (DSS), and recurrence-free survivals (RFS) were compared according to tumor location and pT category. Anterior and posterior tumors were 43.5% and 56.5%, respectively, 78.8% of lesions were T3 and 21.2% were T4a. Five-year OS, DSS, and RFS for T3 were 74.1%, 80.5%, and 63.4%, respectively, and for T4a 71.8%, 71.8%, and 43%, respectively (p not significant). In relation to tumor location, the survival outcomes were 91%, 94.1%, and 72.6%, respectively, for anterior tumors, and 60.3%, 66.3%, and 49.1%, respectively, for posterior lesions (statistically significant differences). These data provide evidence that laryngeal compartmentalization is a valid prognosticator, even more powerful than the pT category.
