Comparative Study
BACKGROUND
Trans-oral robotic surgery (TORS) and primary radiotherapy are the two modalities used to treat early T stage oropharyngeal squamous cell carcinoma(OPSCC). Prior literature including a recent randomized controlled trial have not shown the superiority of one modality over the other. When the modalities have similar outcomes, cost-effectiveness have an important role in deciding on the appropriate treatment. There are economic evaluations comparing the two modality with contradicting conclusions. The purpose of this review is to synthesise the evidence.
METHODS
This is a systematic review of economic evaluations on the treatment modalities for OPSCC, namely TORS versus radiotherapy. The main outcome measures were the Cost-utility results reported as the effectiveness and costs separately and as part of the Incremental Cost-Effectiveness Ratio.
RESULTS
Literature search identified five articles reporting cost-utility analysis, eligible for the review. A strategy is considered to be dominant when the effectiveness achieved was more at a lower cost, compared to the comparator. At the willingness to pay (WTP) threshold of 50,000 to 100,000 USD per Quality Adjusted Life-Year (QALY), three studies showed dominance of strategies in the base case analysis (TORS in two and Primary Chemoradiotherapy in one). Two of the articles studied node negative patients, one of them favored TORS. Three articles had node positive patients and two of them favored TORS and one favored chemoradiotherapy in the base case analysis. On sensitivity analysis, adjuvant treatment was found to be the detrimental factor affecting the cost-effectiveness.
CONCLUSIONS
TORS can be considered a cost-effective strategy in early T stage OPSCC, if the addition of adjuvant therapy involving radiotherapy can be avoided. Literature have shown that around 70% of the early cancers would require adjuvant treatment. This implies the importance of case selection while considering TORS as the initial treatment modality.

Meta-Analysis Review
BACKGROUND
There is a well documented racial disparity in overall survival for oropharyngeal squamous cell carcinoma (OPSCC); however, it is unknown to what extent this disparity varies by HPV-status.
METHODS
A literature search was conducted through December 2019 using Ovid Medline, Cochrane Library, Embase, Scopus, and Clinicaltrials.gov. PRISMA guidelines were followed. A meta-analysis was conducted using random effects models to obtain pooled hazard ratios (HRs).
RESULTS
Of 649 studies initially identified, 20 studies met criteria for the narrative review. There were four studies evaluating survival by race in HPV-positive OPSCC and five studies in HPV-negative OPSCC suitable for pooling. The pooled HR associated with black race was 1.10 (95% CI 0.96-1.23) among patients with HPV-positive (n = 23 608) and 1.50 (95% CI 1.12-1.88) among patients with HPV-negative (n = 12 112). There was notable heterogeneity (I = 83%) and publication bias among the HPV-negative OPSCC studies.
CONCLUSIONS
The racial disparity in OPSCC survival persists for HPV-negative disease and is nonsignificant for HPV-positive disease. Unmeasured differences in socioeconomic status and access to care may contribute to this disparity.

Review
Oropharyngeal cancer is a multifactorial disease. Alcohol and tobacco are the main risk factors. Radon is a human carcinogen linked to lung cancer risk, but its influence in other cancers is not well known. We aim to assess the effect of radon exposure on the risk of oral and pharyngeal cancer through a systematic review of the scientific literature. This review performs a qualitative analysis of the available studies. 13 cohort studies were included, most of them mortality studies, which analysed the relationship between occupational or residential radon exposure with oropharyngeal cancer mortality or incidence. Most of the included studies found no association between radon exposure and oral and pharyngeal cancer. This lack of effect was observed in miners studies and in general population studies. Further research is necessary to quantify if this association really exists and its magnitude, specially performing studies in general population, preferably living in areas with high radon levels.

No study has systematically reviewed the evidence on presentation of oropharyngeal dysphagia and swallowing rehabilitation following esophagectomy. The purposes of this systematic review are to 1) qualitatively synthesize the current findings on oropharyngeal swallowing abnormalities identified by instrumental swallowing evaluations, 2) describe the reported health-related outcomes in relation to swallowing abnormality following esophagectomy, and 3) examine the efficacy of reported rehabilitative interventions for oropharyngeal dysphagia in patients who underwent esophagectomy. Publications were searched using five electronic databases. No language or publication date restrictions were imposed. Two authors performed a blind review for published or unpublished studies that reported swallowing biomechanics and dysphagic symptoms using instrumental evaluation of swallowing, specifically the videofluoroscopic swallowing study and fiberoptic endoscopic evaluation of swallowing, and/or health-related outcomes in relation to swallowing abnormalities, and/or therapeutic interventions for oropharyngeal dysphagia following esophagectomy. Twelve studies out of 2,193 studies including 458 patients met the inclusion criteria. Reported abnormal swallowing biomechanics included vocal fold immobility, delayed onset of swallowing, reduced hyolaryngeal elevation, and reduced opening of the upper esophageal sphincter. Aspiration (0-81%) and pharyngeal residue (22-100%) were prevalent. Those abnormal swallowing biomechanics and swallowing symptoms were commonly reported following both transhiatal and transthoracic esophagectomy. Pneumonia presented in 5-25% of the study patients. One quasi-experimental study examined the effectiveness of swallowing exercises for postoperative oropharyngeal dysphagia; three case series reported a benefit of the chin-tuck maneuver in reducing aspiration and residue. This review revealed distinct swallowing impairments and increased pneumonia risks following esophagectomy. This review also found that evidence on the efficacy of therapeutic interventions was limited. Future studies are warranted to develop effective rehabilitative interventions for postesophagectomy patients with oropharyngeal dysphagia.

Meta-Analysis Review
Human papillomavirus (HPV)-associated oropharyngeal cancer (OPC) is rapidly increasing in incidence and has a favourable prognosis compared with HPV-negative disease. Current combined therapies include significant risks of morbidity for the growing group of survivors. This systematic review and meta-analysis investigates how treatment affects quality of life (QoL) in survivors of oropharyngeal cancer. PubMed, EMBASE and the Cochrane Library were systematically searched for all studies reporting patient-assessed QoL at least 1 year after treatment for OPC. In a meta-analysis, weighted average QoL scores from the four most commonly utilised QoL instruments were compared with baseline and reference group scores using the concept of minimal clinically important difference. The meta-analysis included data from 1366 patients from 25 studies and 12 countries. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30) was answered by 704 patients, 644 patients answered the EORTC QLQ Head and Neck-35 (H&N-35), 474 patients answered the University of Washington Quality of Life Questionnaire, and 381 patients answered the M. D. Anderson Dysphagia Inventory. Moderate to large clinically important deteriorations in QoL were found in the domains dry mouth and sticky saliva for the EORTC QLQ-H&N35, saliva, chewing, swallowing, speech, taste, appearance and shoulder for the University of Washington Quality of Life Questionnaire, and the global, physical and emotional subscales for the M. D. Anderson Dysphagia Inventory. In conclusion, survivors of OPC face clinically important deteriorations in QoL that most markedly centre on xerostomia, dysphagia and chewing. These ailments indicate a potential for improvement in patient management.

Comparative Study Meta-Analysis Review
Efficacy, outcomes, and complication rates of different surgical and nonsurgical treatment modalities for recurrent/residual oropharyngeal carcinoma: A systematic review and meta-analysis.
BACKGROUND
Treatment of recurrent oropharyngeal cancer is widely thought to have poor outcomes. Justification for treatment, especially in advanced cases, can be difficult.
METHODS
A systematic search of MEDLINE, Embase, and Cochrane databases was conducted. Included studies reported specific recurrent oropharyngeal cancer survival data.
RESULTS
Twenty-two retrospective studies were included. Pooled 3-year overall survival (OS) was 26% (95% confidence interval [CI] = 22% to 29%; I squared = 40.7%; p = .057). Pooled 5-year OS was 23% (95% CI = 20% to 27%; I squared = 73.9%; p = .000). Surgical treatment was superior to radiation (5-year OS 26% vs 16%, respectively; p < .001). The 5-year OS improved over time: 18% in the pre-2000 cohort; 35% in the mixed pre-2000 and post-2000 group; and 51% in the post-2000 cohort (p < .001).
CONCLUSION
Outcomes have improved considerably over the last 2 decades, resulting in approximately 50% overall 5-year survival. Human papillomavirus (HPV) status, patient selection, and improvements in care may explain this. © 2016 The Authors Head & Neck Published by Wiley Periodicals, Inc.

Meta-Analysis Review
OBJECTIVE
Studies have demonstrated that tonsillectomy may alter the risk of oropharyngeal cancer (OPC). We systematically reviewed the evidence and pooled data to examine such an association.
METHODS
PubMed, Embase, and Scopus were searched up to 25 April 2023. Studies reporting an association between tonsillectomy and oropharyngeal cancer risk at any site were included.
RESULTS
Five studies were eligible. All examined the risk of tonsillar and base of the tongue (BOT) cancer with prior history of tonsillectomy. On meta-analysis of the data, prior history of tonsillectomy was associated with a significantly decreased risk of tonsillar cancer. The second meta-analysis showed that history of tonsillectomy did not significantly alter the risk of BOT cancer. However, after exclusion of one study, the results showed an increased risk of BOT cancer with a history of tonsillectomy.
CONCLUSIONS
The scarce data available in the literature suggests that tonsillectomy may reduce the risk of tonsillar cancer but does not alter the risk of BOT cancer. Further studies are needed to explore the association between tonsillectomy and the risk of OPC.

Meta-Analysis Review
PURPOSE
The objectives of this study were (1) to systematically review current definitions of head and neck squamous cell carcinoma (HNSCC) recurrence and (2) to propose a definition of locally recurrent HNSCC.
METHODS
A systematic literature review was performed according to the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' statement in Medline, Embase, and Cochrane databases guided by the study question "What is the definition of local recurrence for patients with HN:SCC?". All retrieved studies were reviewed and qualitatively analyzed.
RESULTS
The systematic literature search resulted in 3467 publications after removal of duplicates. Forty studies were examined as full text, and a total of five were found suitable for inclusion. All five included studies dealt with definitions of second primary HNSCC and were based on the Warren and Gates Criteria; (1) each of the tumors are malignant, (2) each must be distinct, and (3) the probability of one being a metastasis of the other must be excluded. Each of the included studies added specific anatomical and/or temporal separation measures to the criteria of second primary HNSCC. We propose the definition of locally recurrent HNSCC to be: (1) Same anatomical subsite or adjacent subsite within 3 cm of the primary lesion, (2) time-interval no more than 3 years (from completed treatment of the primary lesion), and (3) same p16-status for oropharyngeal carcinomas.
CONCLUSIONS
No uniform definition of locally recurrent HNSCC currently exists. We propose the Odense-Birmingham definition based on the anatomical subsite combined with a specific measurable distance and a temporal separation of three years.

Meta-Analysis
This work examined published papers of patients affected by human papillomavirus-related head and neck adenosquamous carcinoma. Demographic data, tumor site and sub-site, TNM stage, HPV status (positive VS negative) and the technique used for its identification, the treatments performed, follow-up time and patient's status at follow-up were assessed. Three papers including 26 patients resulted eligible for the study. The incidence of HPV-positive Adenosquamous Carcinomas located in the oropharynx was significantly higher than HPV-negative tumors (p = 0.01), especially if the origin of primary unknown tumors was considered within this anatomical site (p < 0.0001). HPV-positive Adenosquamous Carcinomas had a higher incidence of small primary tumor (Tx + T1) (p = 0.03) and bulky cervical lymph node metastasis (N2) at presentation (p = 0.02). HPV-positive and HPV-negative tumors had similar OS and DFS. Head & Neck HPV-positive Adenosquamous Carcinoma seems to act like HPV-positive conventional Squamous Cell Carcinoma, thus we suggest to determine the HPV status of Adenosquamous Carcinoma during the diagnostic phase.

Review
INTRODUCTION
This systematic review aims to evaluate the role of biopsies in non-oropharyngeal subsites in patients with cervical metastasis from head and neck squamous cell carcinoma of unknown primary (HNSCCUP).
METHODS
This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Articles that encompassed non-oropharyngeal biopsies in HNSCCUP as part of the diagnostic work-up were selected and analysed.
RESULTS
A comprehensive search strategy was used to search relevant literature in PubMed from inception to October 2021. Eleven articles out of 860 were included, comprising 990 patients. There are no randomised control trials comparing the outcomes of survival and or locoregional control between patients who have or have not undergone non-targeted biopsies of non-oropharyngeal sub-sites for HNSCCUP. Several retrospective studies which showed an extremely low yield from random biopsies (range of yield, 0%-9%) of non-oropharyngeal subsites. Even targeted biopsies showed a low yield (range of yield, 0.6%-16.6%) from non-oropharyngeal subsites. The primary site identified for Epstein-Barr virus (EBV) positive cervical lymph nodes with an unknown primary is mainly the nasopharynx (51.7%). Narrow band imaging (NBI) (sensitivity range, 64%-91%) helps in the detection of primaries to target biopsies in non-oropharyngeal subsites.
CONCLUSIONS
On the basis of this systematic review, it is not appropriate to offer biopsies of clinically and radiologically normal upper aerodigestive tract mucosa at non-oropharyngeal sites. Offer nasopharyngeal biopsies when the cervical node sampling reveals EBV-positive metastasis. Where available, NBI should be used to help detect and target biopsies in non-oropharyngeal subsites.
