Meta-Analysis Review
BACKGROUND
Advanced hypopharyngeal carcinoma has a dismal prognosis. The optimal treatment for these patients remains under debate. This systematic review aimed to compare survival following surgical and non-surgical treatments.
METHODS
A systematic review was conducted of randomised studies, with a descriptive analysis of retrospective observational studies.
RESULTS
Two randomised trials and 11 observational studies were included in the review. A meta-analysis of randomised trials reported a hazard ratio of 0.89 for overall survival in favour of surgical treatment (p = 0.44). Neither treatment was favoured in terms of overall survival. Observational studies did not report a survival advantage with either treatment. The five-year larynx preservation rates for non-surgically treated patients were between 38 and 58 percent.
CONCLUSION
Chemoradiotherapy offers similar survivorship compared to surgery in advanced disease, while also making larynx preservation feasible. It can be used as a treatment in all patients as an alternative to surgery.

Meta-Analysis Review
The aim of this meta-analysis was to determine the diagnostic test accuracy of sentinel lymph node biopsy (SLNB) in patients with oropharyngeal, laryngeal, and hypopharyngeal squamous cell carcinoma (SCC). For this purpose, MEDLINE, EMBASE, and Web of Science were searched from inception to March 8, 2022. Included were studies evaluating diagnostic test accuracy of SLNB to identify cervical lymph node metastases with elective neck dissection or follow-up as reference. A bivariate generalized linear mixed model approach was used for the meta-analysis. Nineteen studies were eligible, evaluating 377 cases in total. The pooled estimates of sensitivity and negative predictive value were 0.93 (95% CI: 0.86-0.96) and 0.97 (95% CI: 0.94-0.98), respectively. The excellent accuracy of SLNB justifies a place in the diagnostic workup of patients with larynx and pharynx SCC. Randomized trials are required to demonstrate oncologic safety and benefits on treatment related morbidity and quality of life when omitting elective neck treatment based on SLNB.

Meta-Analysis Review
The present study aimed to evaluate the effectiveness and safety of various salvage treatments to treat locally recurrent nasopharyngeal carcinoma (IrNPC). A comprehensive search was conducted to gather relevant research publications on salvage treatment for IrNPC. Specifically, 2-, 3-, and 5-year overall survival were the primary outcome. A total of 89 studies with 101 cohorts were collected. Endoscopic nasopharyngectomy was found to be associated with a significantly improved 5-year OS compared with CRT (p = 0.027) and IMRT (p = 0.016). Moreover, based on recurrence T classification, the 2-, 3-, and 5-year OS were similar across different treatments. Endoscopic nasopharyngectomy was associated with a significant reduction in treatment-related complications (grade ≥ 3) compared with IMRT (p < 0.001) and open nasopharyngectomy (p = 0.028). Endoscopic nasopharyngectomy may provide comparable treatment outcomes to re-irradiation, while offering a better safety profile for selective patients with resectable IrNPC.

BACKGROUND
Nasopharyngeal cancer (NPC) is a type of malignancy that is highly prevalent in Asian countries. Therefore, an understanding between NPC epidemiological trend, the clinico-pathological and aetiological profiles are needed. This systematic review focuses on asian countries demographic and clinico-pathological presentation reported in 9982 NPC cases diagnosed from the year 2010 to 2021.
METHODOLOGY
Data were extracted from databases, such as PubMed, Springer Link, Science Direct, Google Scholar and general search engines, by using pre-determined keywords (e.g. clinico-pathological data, age, sex, tumour stage, nasopharyngeal cancer, nasopharyngeal carcinoma, naso-pharynx and cancer in Asia).
RESULTS AND CONCLUSION
Findings from our systematic review shows that from 2010 to 2021, males in age range below 50 years old are at a higher risk of developing NPC in Asia. NPC is mostly diagnosed at advanced stage in Asia, which is likely due to the deep-seated location of the cancer. Type III NPC and EBV proteins (EBNA1 and LMP2A) are frequently associated with reported EBV-positive NPC cases in Asian countries. Meanwhile, NPC type I, II, and III are associated with EBV-negative NPC cases in Asia. Human leucocyte antigen (HLA) alleles (A2, B27, and B46) are frequently present in reported EBV-negative NPC cases in Asia. In Asia, males below 50 years old are more prone to NPC and often diagnosed at late stage. EBV-positive and EBV-negative NPC in Asia have unique histological profiles. Systemic approach of this study may help to provide better knowledge on reported NPC cases especially on the risk factors and clinical presentation focusing in Asian countries.

Review
OBJECTIVE
To perform a systematic review of the literature available about the posterior pharyngeal wall squamous cell carcinomas, with a special focus on oncologic outcomes.
METHODS
A comprehensive research was performed on PubMed/MEDLINE, Google Scholar, and Cochrane Library datasets for published studies meeting the established criteria. The last search was conducted on December 8, 2019.
RESULTS
Eleven studies were included in the review, for a total of 534 patients (median age 60.4; male: n = 359, 67.2%). Six of the studies evaluated the oncologic outcomes of primary surgery, while three studies focused on results achieved through primary radiotherapy. Two studies evaluated both surgery and radiotherapy outcomes for the treatment of early or advanced posterior pharyngeal wall carcinoma.
CONCLUSIONS
Primary surgery associated with adjuvant radiotherapy would seem to ensure better oncologic outcomes, especially for locally advanced tumors. Moreover, this systematic review showed that oro- and hypo-pharyngeal wall tumors are similar in terms of clinical and biological behavior.

Meta-Analysis Review
OBJECTIVE
The scientific literature presents conflicting data on a possible causal relationship between opium users and the development of head and neck cancer (HNC). This study aimed to explore the risk of HNC among opium users is a narcotic addictive drug.
DESIGN
A systematic review and meta-analysis encompassed academic databases and gray literature up to May 2023, focusing on epidemiologic observational studies that reported the effect size of the HNC risk and opium use.
RESULTS
This study incorporated 14 effect size estimations to examine the association between opium use and the risk of head and neck cancers based on various HNC sub-sites, including the lip and oral cavity, pharynx, and larynx. The random effect model revealed a significant correlation between combined HNCs and opium use (odds ratio [OR]: 4.88; 95 % confidence interval [CI]: 2.99, 7.96). Additionally, opium consumption significantly increased the incidence of lip and oral cavity cancers (OR: 1.82; 95 % CI: 1.25, 2.65). Opium users faced an approximately eightfold increase in laryngeal cancer risk (OR: 7.86; 95 % CI: 4.66, 13.24) compared to non-opium users.
CONCLUSIONS
In summary, our findings strongly suggest that opium use is emerging as a significant risk factor for HNC. This underscores the need for further research and focused preventive measures to address this concerning association.

Meta-Analysis Review
IMPORTANCE
Helicobacter pylori colonization contributes significantly to multiple disease states, but its role in the development of tonsillar infection is unclear. Understanding the causes of chronic tonsillitis is important in clinical decision making of this commonly treated disease.
OBJECTIVE
To assess the correlation between H pylori colonization of tonsillar tissue in chronic tonsillitis and in noninfectious hyperplastic tonsils.
DATA SOURCES
We searched PubMed, MEDLINE, the Cochrane Trial Registry (through June 2014) and relevant article bibliographies.
STUDY SELECTION
Systematic review and meta-analysis of studies assessing the correlation between H pylori colonization in tonsillar tissues of patients undergoing tonsillectomy for either chronic tonsillitis or noninfectious causes. Included studies hypothesized that H pylori played a role in the development of chronic tonsillitis. All included studies investigated the presence of H pylori in tonsillar tissue removed for various indications. Included studies must have used an accepted method of testing for H pylori.
DATA EXTRACTION AND ANALYSIS
Studies were systematically reviewed by 2 independent reviewers for inclusion. Reported results of H pylori testing between tissues removed for infectious or noninfectious causes were systematically reviewed. The odds ratio of Hpylori colonization in tissue removed for chronic tonsillitis compared with tissue removed for noninfectious causes was calculated using a random-effects model.
RESULTS
Six studies met inclusion criteria and had suitable data for pooling (n = 436). Of these, 2 studies measured H pylori colonization of tonsillar tissue in pediatric populations. One study analyzed tissue in both adult and pediatric populations. Noninfectious indications for tonsillectomy included sleep apnea or sleep-related breathing disorder, obstruction, carcinoma, and tonsillar hypertrophy. Overall, tonsillar H pylori colonization was found not to be significantly present more often in tissue samples removed secondary to recurrent infection rather than to noninfectious indications. The odds ratio of H pylori colonization in the tonsils of patients with chronic tonsillitis was 1.993 (95% CI, 0.909-4.371) (P = .09).
CONCLUSIONS AND RELEVANCE
Helicobacter pylori colonization was not found to be more prevalent on tonsillar tissue with chronic or recurrent infections. The reviewed studies provide no evidence that H pylori infection plays a role in the pathogenesis or development of chronic tonsillitis.

Meta-Analysis Review
BACKGROUND
Infection with human papillomavirus (HPV) is necessary for the development of cervical carcinoma. By contrast, the role of HPV in the pathogenesis of other malignancies, such as head and neck cancers, is less well characterised. This study aimed to address key information gaps by conducting a systematic review and meta-analysis of the prevalence of HPV infection in head and neck cancers, focusing on data for European populations.
METHODS
MEDLINE, Embase and grey literature sources were systematically searched for primary studies that were published in English between July 2002 and July 2012, and which reported on the prevalence of HPV infection in head and neck cancers in European populations. Studies on non-European populations, those not published in English, and those assessing patients co-infected with human immunodeficiency virus were excluded. Eligible studies were combined in a meta-analysis. In addition, the potential statistical association between the head and neck cancers and certain HPV types was investigated.
RESULTS
Thirty-nine publications met the inclusion criteria. The prevalence of HPV of any type in 3,649 patients with head and neck cancers was 40.0% (95% confidence interval, 34.6% to 45.5%), and was highest in tonsillar cancer (66.4%) and lowest in pharyngeal (15.3%) and tongue (25.7%) cancers. There were no statistically significant associations between the HPV types analysed and the geographical setting, type of sample analysed or type of primer used to analyse samples in head and neck cancers.
CONCLUSIONS
The prevalence of HPV infection in European patients with head and neck cancers is high but varies between the different anatomical sites of these malignancies. There appears to be no association between HPV type and geographical setting, type of samples analysed or type of primer used to analyse samples in such cancers.

INTRODUCTION
Oral human papillomavirus infection amplifies the risk for oropharyngeal cancer. Human papillomavirus-associated cancers in otorhinolaryngology have typical characteristics.
PATIENTS AND METHODS
To improve understanding of management, therapy and prognosis of patients with oropharyngeal human papillomavirus-associated cancers a systematic review of the literature was reported. Medline, The Cochrane Library, Embase and Scielo electronic databases were searched. The search included published articles up to December 2006. A wide search strategy was employed in order to avoid publication biases and to assess studies in which the main aspects concerning oropharyngeal squamous cell carcinoma and human papillomavirus management are analyzed.
RESULTS
A total of 120 articles were identified, of which 16 matched the inclusion criteria.
DISCUSSION
Patients with human papillomavirus-associated oropharyngeal cancers have distinctive risk factors such as a high number of sex partners. They are typically younger, nonusers of tobacco and alcohol and have a better prognosis.

Meta-Analysis
BACKGROUND
Nasopharyngeal cancer (NPC), despite being one of the most malignant head and neck carcinomas (HNC), lacks comprehensive prognostic biomarkers that predict patient survival. Therefore, this systematic review and meta-analysis is aimed to evaluate the potential prognostic value of miRNAs as prognostic biomarkers in NPC.
METHODS
PRISMA guidelines were used to conduct this systematic review and meta-analysis study. Permutations of multiple "search key-words" were used for the search strategy, which was limited to articles published between January 2012 and March 2018. The retrieved articles were meticulously searched with multi-level screening by two reviewers and confirmed by other reviewers. Meta-analysis was performed using Hazard Ratios (HR) and associated 95% Confidence Interval (CI) of survival obtained from previously published studies. Publication bias was assessed by Egger's bias indicator test and funnel plot symmetry.
RESULTS
A total of 5069 patients across 21 studies were considered eligible for inclusion in the systematic review, with 65 miRNAs being evaluated in the subsequent meta-analysis. Most articles included in this study originated from China and one study from North Africa. The forest plot was generated using cumulated survival data, resulting in a pooled HR value of 1.196 (95% CI: 0.893-1.601) indicating that the upregulated miRNAs increased the likelihood of death of NPC patients by 19%.
CONCLUSION
To our knowledge, this is the first meta-analysis that examines the prognostic effectiveness of miRNAs as biomarkers in NPC patients. We noted that the combined effect estimate of HR across multiple studies indicated that increased miRNA expression in NPC potentially leads to poor overall survival. However, further large-scale prospective studies on the clinical significance of the miRNAs, with sizable cohorts are necessary in order to obtain conclusive results.
