Meta-Analysis Review
PURPOSE
To evaluate the efficacy and oncologic outcomes of transoral laser microsurgery (TLM) for recurrent laryngeal carcinoma after previous treatment.
MATERIALS AND METHODS
A systematic search in PubMed was performed using mesh word for "laryngeal cancer," crossed with "recurrent," and "TLM." The primary endpoints, including overall survival (OS) rate, local control rate, and disease-specific survival (DSS) were summarized using RevMan software. Adverse events and complications were recorded if reported.
RESULTS
The pooled odds ratios (ORs) for main outcomes, including local control, 5-year OS, and DSS were 3.08 (95% confidential indexed [95% CI], 1.88-5.05), 2.29 (95% CI, 1.42-3.67), and 5.05 (95% CI, 2.75-9.27), respectively. The pooled OR for functional outcome, larynx preservation, was 3.82 (95% CI, 2.46-5.94), whereas the pooled risk difference of local recurrence was 45% (95% CI, 26-64%).
CONCLUSIONS
It seems that TLM is an effective option for recurrent laryngeal cancer with regard to the high incidence of OS, local control, and especially organ preservation. However, more prospective studies are needed to confirm its efficiency.

Review
BACKGROUND
Human papillomavirus targets the skin and mucous membranes, producing benign hyperplastic lesions and precancerous and cancerous lesions. An increasing number of head and neck cancersin particular, oropharyngeal squamous cell carcinoma, laryngeal squamous cell carcinoma, and oral squamous cell carcinoma, are attributable to HPV infection. HPV-induced HNCs typically affect younger, nonsmoking patients with no prior history of heavy alcohol use, more extensive sexual history, and higher socioeconomic status.
AIM
The purpose of the review is to present the most recent and well-established findings concerning HPV-induced head and neck cancers and consequently to provide medical specialists with essential information regarding the epidemiology, the role of HPV in HNC cancerogenesis, prevention, diagnosis, and treatment.
MATERIAL AND METHODS
All authors independently have searched The EMbase, Medline/Pubmed, and Cochrane databases by using the following keywords "head and neck cancer", "human papillomavirus", "HPV", "HPV biology", "oropharyngeal squamous cell carcinoma", "carcinogenesis", "transoral surgery", "robotic surgery". The last search was conducted in March 2022. The references of the publications of interest were also screened for relevant papers. There were no limitations in regard to the publication date.
CONCLUSION
Aiming to avoid the epidemic of HPV-induced HNC, it is paramount to improve the access to vaccination as well as resolve parental concerns regarding vaccine safety. Physicians should rely on reduced-dose radiation and aim to reduce the overall treatment time. Thanks to a more elaborate understanding of the genomic background of HPV-induced HNC, precision medicine could become a relevant part of patients' management. In comparison to traditional techniques and non-operative treatment, transoral robotic surgery (TORS) offers similar oncologic and functional outcomes, with a possible benefit on long-term quality of life. However, more research is needed to establish clear guidelines indicating when TORS resections should be supported with adjuvant therapy.

Meta-Analysis
BACKGROUND
Several recent studies have indicated that the lymph node ratio (LNR) is an independent prognostic factor for laryngeal and hypopharyngeal squamous cell carcinoma (LHSCC). The purpose of this paper is to assess the prognostic value of LNR and explore appropriate cutoff values by conducting a systematic review and meta-analysis.
METHODS
Pubmed, Embase (via Ovid), and Cochrane library were systematically searched for studies on the prognostic value of LNR in LHSCC up to October 31, 2019. Then, Literature review, data extraction, and quality assessment of eligible studies were performed by two independent reviewers back-to-back. Lastly, Stata 14.0 software was hired to conduct a meta-analysis.
RESULTS
A total of 445 articles were retrieved, and 13 studies published in English between 2013 and 2019 were included after the title/abstract and full-text screening. Among the 13 studies contributed to 4197 patients, seven studies were about hypopharyngeal squamous cell carcinoma (HPSCC), four studies about laryngeal squamous cell carcinoma (LSCC), and the remaining two studies about LHSCC. The meta-analysis results showed that shorter overall survival (OS) (HR 1.49; 95%CI: 1.18 to 1.88), disease-specific survival (DSS) (HR 1.66; 95%CI: 1.32 to 2.07) and disease-free survival (DFS) (HR 2.04; 95%CI: 1.54 to 2.71) were significantly correlated with a higher LNR in a random-effect model. The cutoff values of eligible studies were varied from 0.03 to 0.14, and the lowest significant LNR was 0.044.
CONCLUSION
LNR is a valuable prognostic factor in the survival of LHSCC and may be used to improve the tumor staging systems, which, however, requires the solid support of more high-quality studies.

Review
The purpose of this study was to evaluate the treatment of clinically negative cervical lymph nodes in supraglottic carcinoma by a meta-analysis. The search words were "supraglottic carcinoma", "cervical lymph nodes negative/cN0", "radical neck dissection", and "radiotherapy". The databases included the Chinese biomedical literature database, Medline, Cochrane library, EMBASE database, journals, and theses, etc. from 1989 onwards. Using the 5-year overall survival, disease-free survival, and disease-specific survival rates, and the recurrence and distant metastasis rates as observation indexes, the proper model and method were selected after a heterogeneity test to allow combined statistic tests, sensitivity analysis, and publication bias analysis to be conducted. Four studies (807 cases) were included in the analysis. Comparisons of the 5-year overall survival, disease-free survival, and disease-specific survival rates as well as lymph node metastasis and the recurrence rate for radical neck dissection and radiotherapy showed no significant differences. There was no advantage of radical neck dissection in supraglottic carcinoma with clinically negative cervical lymph nodes compared to radiotherapy. However, owing to the lack of a prospective study and large number of cases, selection bias and measurement bias may still exist.

Review
BACKGROUND
The aim of this systematic review is to provide an overview of the diagnosis, treatment options and treatment-related complications of cervical esophageal carcinoma (CEC) and to subsequently provide recommendations to improve quality of care.
DESIGN
Studies were identified in PubMed, EMBASE and Web of Science. A total of 107 publications fulfilled the inclusion criteria and were included.
RESULTS
CEC is uncommon, accounting for 2%-10% of all esophageal carcinomas. These tumors are often locally advanced at presentation and have a poor prognosis, with a 5-year overall survival of 30%. Tobacco and alcohol consumption seem to be the major risk factors for developing CEC. Surgery is usually not possible due to the very close relationship to other organs such as the larynx, trachea and thyroid gland. Therefore, the current standard of care is definitive chemoradiation (dCRT) with curative intent. Treatment regimens used to treat CEC are adapted by established regimens in lower esophageal squamous cell carcinoma and head and neck squamous cell carcinoma. However, dCRT may be accompanied by severe side-effects and complications. Several diagnostic and predictive markers have been studied, but currently, there is no other biomarker than clinical stage to determine patient management. Suggestions to improve patient outcomes are to determine the exact radiation dose needed for adequate locoregional control and to combine radiotherapy with optimal systemic therapy backbone.
CONCLUSION
CEC remains unchartered territory for many practising physicians and patients with CEC have a poor prognosis. To improve the outcome for CEC patients, future studies should focus on the identification of new diagnostic biomarkers or targets for radiosensitizers, amelioration of radiation schedules, optimal combination of chemotherapeutic agents and/or new therapeutic targets.

Review
Over the past few decades, several publications have investigated the role of Epstein-Barr virus (EBV) in head and neck squamous cell carcinomas, and an increasing number of them have shown its presence in laryngeal tumors. The purpose of this meta-analysis was to evaluate the association of EBV with laryngeal carcinoma. The search was carried out in two databases, Scopus and PubMed, using the following terms: "Epstein-Barr virus" and "laryngeal carcinoma". A total of 187 records were found, of which 31 were selected for meeting the inclusion and exclusion criteria. The meta-analysis yielded an overall pooled prevalence of 43.72% (95% confidence interval (CI): 34.35-53.08). Studies carried out in Europe and Eurasia had slightly higher pooled prevalence than other subgroups, while the prevalence of studies performed in developed countries was higher than in developing countries (46.37% vs. 34.02%). Furthermore, laryngeal carcinoma occurred almost three times as often among EBV-infected individuals compared to those without EBV infection (odds ratio = 2.86 (95% CI: 1.18-6.90); Begg's test, = 0.843 and Egger's test, = 0.866). Our findings support the idea that EBV is related to laryngeal carcinoma. However, further studies are needed before recognizing a definitive etiological role of EBV in the development and/or progression of laryngeal carcinomas.

(Review)
Review
Laryngeal squamous cell cancer (LSCC) is one of the most common malignant tumors of the head and neck region, with a poor survival rate (5-year overall survival 50-80%) as a consequence of an advanced-stage diagnosis and high recurrence rate. Tobacco smoking and alcohol abuse are the main risk factors of LSCC development. An early diagnosis of LSCC, a prompt detection of recurrence and a more precise monitoring of the efficacy of different treatment modalities are currently needed to reduce the mortality. Therefore, the identification of effective diagnostic and prognostic biomarkers for LSCC is crucial to guide disease management and improve clinical outcomes. In the past years, a dysregulated expression of small non-coding RNAs, including microRNAs (miRNAs), has been reported in many human cancers, including LSCC, and many miRNAs have been explored for their diagnostic and prognostic potential and proposed as biomarkers. We searched electronic databases for original papers that were focused on miRNAs and LSCC, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. According to the outcome, 566 articles were initially screened, of which 177 studies were selected and included in the analysis. In this systematic review, we provide an overview of the current literature on the function and the potential diagnostic and prognostic role of tissue and circulating miRNAs in LSCC.

Meta-Analysis Review
Residual or recurrent laryngeal cancer after irradiation is a difficult clinical problem with a rate that ranges from 13% to 36% of cases. Supracricoid laryngectomy (SCL) with cricohyoidopexy (CHP) or cricohyoidoepiglottopexy (CHEP) provide reliable oncological and functional results for selected primary and recurrent patients with glottic and supraglottic carcinomas. We conducted a systematic review and meta-analysis to assess the oncological and functional outcomes of patients treated with open partial horizontal laryngectomy types IIa and IIb (CHEP, CHP) in terms of the recurrence of squamocellular cancer of the larynx after radiotherapy failure. The databases searched included MEDLINE, PubMed and EMBASE (from January 1990 to December 2015, English language). The meta-analysis was performed with a mixed random effects model using the DerSimonian and Laird method. The heterogeneity was measured with the I statistic. Fourteen papers out of 276 were included and comprised a total of 291 patients. The five-year overall survival was 80.2% (CI 0.719-0.885; I = 62%; p = 0.003), and the 5-year disease-free survival was 89.5% (CI 0.838-0.952; I = 52%; p = 0.022). The indications for SCL after the failure of radiation therapy (RT) were similar to those specified for previously untreated patients. We therefore hypothesised that careful assessment of tumour extension might be responsible for the high 5-year OS and 5-year DFS. The early postoperative recovery outcomes indicated that the mean time until decannulation was 35.6 days (CI 24.3-46.9; I = 95%; p < 0.001), and the mean time until nasogastric tube (NGT) or percutaneous endoscopic gastrostomy (PEG) removal was 28.3 days (CI 22.7-33.8; I = 86%; p< = 0.001). These data are according to authors who prefer the initial removal of the NGT and the initiation of oral alimentation with a tracheostomy tube to protect and clean the airways and permit the suction of any residual food that might be present.

Review
Horizontal glottectomy (HG) is a particular type of partial laryngectomy indicated for exclusive glottic tumor with anterior commissure involvement. The purpose of this study is to systematically review the literature about functional and oncological outcome of HG. This systematic review adhered to the recommendations of the PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-analysis) 2009 guidelines. Articles mentioning patients undergoing HG for laryngeal squamous cell carcinoma were included. A total of 14 articles were selected and reviewed from 19 identified. The whole study population consisted of 420 patients who underwent HG. Three hundred and thirty-nine patients out of 359 were staged as T1. The range of post-operative follow-up was 5 months to 10 years. Fifty-five recurrences were experienced, being local, regional and distant in 35, 12 and 8 patients, respectively. Laryngeal preservation rate was 93.6%. Nasogastrict tube was removed on average after 10.1 days. The tracheostomy was maintained for 11.3 days. Mean hospitalization lasted for 11.7 days. According to the results of this systematic review, HG is an oncologically safe surgical option for T1a-T1b glottic tumors with oncological outcomes comparable to other treatment. HG could be a good therapeutical choice whenever poor laryngeal exposure and/or patient's refusal of radiotherapy are encountered, or when patient's medical history represents a contraindication for radiation therapy.

Meta-Analysis Review
BACKGROUND
Although guidelines indicate that thyroidectomy should be performed routinely during total laryngectomy in patients with advanced laryngeal cancer, its clinical indications remain controversial. Some researchers believe that thyroid invasion is uncommon and that thyroid preservation should be considered in most cases.
OBJECTIVE
This study aimed to identify the incidence and predictors of thyroid invasion in patients with laryngeal cancer to facilitate decision-making regarding whether to perform thyroidectomy during total laryngectomy.
MATERIALS AND METHODS
The author conducted a systematic review and meta-analysis of all published articles retrieved from a search of the MEDLINE (1982-2020) and EMBASE (1971-2020) databases. The published studies of advanced laryngeal cancer with total laryngectomy and partial or total thyroidectomy for laryngeal cancer were selected. The incidence and predictors of thyroid invasion were analyzed.
RESULTS
We analyzed 25 studies (2177 cases), of which 176 people (8.08%) had thyroid invasion. Subglottic tumors (odds ratio [OR], 3.74; 95% CI, 1.75-7.99), T4 stage tumors (OR, 2.39; 95% CI, 1.20-4.75), subglottic extension (OR, 3.85; 95% CI,2.09-7.11), and thyroid cartilage invasion (OR, 3.98; 95% CI, 1.47-10.75) are risk factors for thyroid invasion, and no statistically significant difference was noted between recurrent tumor and thyroid invasion.
CONCLUSION
The risk of thyroid invasion was significantly higher when advanced laryngeal cancer involved subglottic tumors, T4 stage tumors, subglottic extension, and thyroid cartilage invasion. The overall incidence of thyroid gland invasion was low; therefore, thyroidectomy may be performed for cases deemed risky rather than as a routine measure of total laryngectomy.
