Review
PURPOSE
To define the oncologic outcomes and the prognostic factors of laryngeal and hypopharyngeal lymphoepithelial carcinoma (LEC).
METHODS
A systematic review and individual patient data analysis were performed according to the PRISMA guidelines. A total of 41 patients (males: 37; mean age: 63.1, standard deviation: 10.0) were included.
RESULTS
The median follow-up time was 36.0 months (interquartile range, IQR: 11.5-73.5), while the median overall survival (OS) time was 96 months (IQR: 39.0-120.0). Estimated disease-specific survival (DSS) rates (95% Confidence Interval, CI; number still at risk) at 1, 3, and 5 years were 94.4% (79.5-98.6; 31), 82.7% (62.7-92.5; 21), and 78.1% (56.8-89.7; 13), respectively. Estimated disease-free survival (DFS) rates (95% CI; number still at risk) at 1, 3, and 5 years were 92.1% (77.4-97.4; 31), 74.9% (55.6-86.8; 21), and 66.6% (46.1-80.8; 13), respectively. Patients undergoing primary surgery had a reduced chance of death from cancer than patients receiving primary radiotherapy (5-year DSS 85.6 vs. 56.2%; p = 0.04), while EBV positivity tend to be a negative prognostic factor (5-year DSS 100 vs. 66.7%; p = 0.05).
CONCLUSIONS
Laryngeal and hypopharyngeal LEC is a rare disease with favorable survival. Further prospective multicenter studies are needed to make a reliable statement on prognosis and outcome, stratifying patients for different therapy regimens and tumor stages.

Tonsillectomy as Prevention of Tonsil and Base of Tongue Cancer: Systematic Review and Meta-analysis on the Immuno-Oncological Effect of One Among the Most Common Surgeries in the World.
Otorhinolaryngology tradition is that tonsillectomy (TE) is conducted among children and adolescents for obstructive sleep apnea secondary to adenotonsillar hypertrophy and in adults for chronic disease of the tonsils and adenoids (recurrent tonsillitis). Nevertheless, over the last 50 years, we have observed a decline in TE worldwide. As a result, there is an emerging concern of a correlated possible increased risk of tonsil cancer (TC) and other subtypes of oropharyngeal squamous cell carcinoma. Since the available data on such topics are limited and controversial, our aim was to elucidate the impact of TE on the incidence mainly of TC through a systematic review of the literature and a meta-analysis of the studies. After a thorough search, 7 retrospective studies were considered eligible for review and meta-analysis (MA). At MA, patients with a history of TE seem to show a reduced risk of TC but a higher predisposition for base of tongue (BOT) cancer (p<0.001): however, the elevated heterogeneity of the studies hampers drawing firm and convincing conclusions (statistical inconsistency >95%). In future, randomized control trials will be welcome to elucidate the prophylactic role of TE against TC and its real impact on BOT cancer.

Meta-Analysis Review
BACKGROUND AND AIMS
Studies evaluating the role of endoscopic submucosal dissection (ESD) in the management of superficial pharyngeal cancers have reported promising results. This meta-analysis evaluates the efficacy and safety of ESD in the management of superficial pharyngeal cancers.
METHODS
We reviewed several databases from inception to September 03, 2020, to identify studies evaluating the efficacy and safety of ESD in the management of superficial pharyngeal cancers. Our outcomes of interest were en bloc resection rate, complete resection rate, adverse events, and rates of local recurrence. Pooled rates with 95% confidence intervals (CI) for all outcomes were calculated using random-effect model. Heterogeneity was assessed by I statistic. We assessed publication bias by using funnel plots and Egger's test. We conducted meta-regression analysis to explore heterogeneity in analyses.
RESULTS
Ten studies were included in analyses. All studies were from Asia. Pooled rates (95% CI) for en bloc resection and complete resection were 94% (87%, 97%) and 72% (62%, 80%), respectively. The pooled rates (95% CI) for adverse events and local recurrence were 10% (5%, 17%) and 1.9% (0.9%, 4%), respectively. Most of the analyses were limited by substantial heterogeneity. On meta-regression analysis, the heterogeneity was explained by size of tumor and histology. Funnel plots and Egger's test showed no evidence of publication bias.
CONCLUSIONS
This meta-analysis including studies from Asian countries demonstrated that ESD is an efficacious and safe option in the management of superficial pharyngeal cancers. More studies and studies from Western countries are needed to further validate these findings.

Review
A systematic review on the molecular and clinical association between Human Papillomavirus and Human Immunodeficiency Virus co-infection in Head, Neck and Oral squamous cell carcinoma.
Head and neck cancer, one of the most commonly prevalent malignancies globally is a complex category of tumours that comprises cancers of the oral cavity, pharynx, and larynx. A specific subgroup of such cancers has been found with some unique chromosomal, therapeutic, and epidemiologic traits with the possibility of affecting via co-infection. About 25% of all head and neck cancers in the population are human papillomavirus infection (HPV)-associated, typically developing in the oropharynx, which comprises the tonsils. In the period of efficient combined antiviral treatment, HPV-positive oral cancers are also becoming a significant contributor to illness and fatality for Human Immunodeficiency Virus (HIV)-infected persons. Although the prevalence and historical background of oral HPV transmission are not thoroughly understood, it seems likely that oral HPV transmission is relatively frequent in HIV-infected people when compared to the overall population. Therefore, there is a need to understand the mechanisms leading to this co-infection, as there is very little research related to that. Hence, this study mainly focus on the therapeutical and biomedical analysis of HPV and HIV co-infection in the above-mentioned cancer, including oral squamous cell carcinoma.

PURPOSE
Given the central role that radiation has in the management of head and neck squamous cell carcinoma of unknown primary origin, it is imperative to review how treatment paradigms have been refined and continue to evolve in the modern era.
METHODS AND MATERIALS
This study was designed based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) statement. A literature search of peer-reviewed publications was undertaken to identify works pertaining to the use of radiation for squamous cell carcinoma of unknown primary origin presenting as cervical lymph node metastases. Articles published from January 2002 to January 2023 with full text available on PubMed and restricted to the English language and human subjects were included. The full bibliographies of identified articles were reviewed and irrelevant studies were removed.
RESULTS
While such breakthroughs as intensity-modulated radiotherapy, positron emission tomography, biomarker testing with immune-histochemistry, and minimally invasive surgical techniques such as transoral robotic surgery have fundamentally changed the approach to this disease in recent decades, controversies still exist with respect to the manner in which radiation is delivered. Although the incidence of head and neck unknown primary cancer is relatively low, questions regarding the necessity of comprehensive radiation using the age-old standard method of targeting the bilateral necks and entire pharyngeal axis to encompass all putative sites of mucosal disease persist.
CONCLUSIONS
Prospective evidence is lacking, and the available studies have been complicated by such factors as the relatively limited sample sizes, as well as the variability in work-up, treatment, inclusion criteria, and follow-up. Regardless, advances in science and technology have ushered in more precise approaches with a high degree of customization, particularly given the increased proportion of patients presenting with human papillomavirus-related disease.

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
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.

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.
