Pleomorphic adenoma is a benign salivary tumor that may recur multifocally. In case series, the benefit of radiation therapy (RT) for recurrent pleomorphic adenoma remains unclear. We hypothesized ...that the combination of surgery and adjuvant RT reduces risk of subsequent recurrence compared with surgery alone for recurrent pleomorphic adenoma.
Patients who received diagnoses of recurrent pleomorphic adenoma between 1980 and 2016 were identified using an institutional pathology database. Medical records were retrospectively reviewed to determine clinical, operative, pathologic, and imaging characteristics. Kaplan-Meier methods were used to estimate local control after surgery, stratified by completeness of resection and receipt of adjuvant RT. The association of variables with risk of subsequent local recurrence was analyzed using Cox proportional hazards model, and variance estimates were calculated to account for multiple recurrences in the same patient. Toxicities were prospectively recorded in a departmental database.
A total of 49 patients presented with at least 1 recurrence, of which 28 were managed with surgery alone, and 21 were treated with surgery and RT. The median follow-up time after the initial recurrence was 48 months (range, 6-531 months). There were 35 subsequent recurrences; 34 after surgery alone and only 1 after surgery with RT. On multivariate analysis, adjuvant RT was associated with decreased risk of recurrence (hazard ratio, 0.09; 95% confidence interval, 0.02-0.41, P = .002), whereas increasing number of prior recurrences was associated with increased risk (hazard ratio, 1.23; 95% confidence interval, 1.13-1.35, P < .001). Common toxicities of RT included dermatitis, xerostomia, and mucositis.
For patients with recurrent pleomorphic adenoma, the addition of adjuvant RT after surgery is associated with a significant decrease in risk of subsequent tumor recurrence.

Objective
To evaluate the concerns and needs of patients and survivors of head and neck cancer (HNC) in the COVID-19 era.
Study Design
Prospective cross-sectional survey.
Setting
Contact lists of 5 ...North American HNC advocacy groups.
Methods
A 14-question survey was distributed to the contact lists of 5 HNC advocacy groups evaluating patient and survivor needs and concerns related to their cancer care and COVID-19.
Results
There were 171 respondents, with 75% in the posttreatment period. The most common concern was contraction of COVID-19 (49%). More patients in active treatment preferred in-person visits than those in the early (≤5 years) and late (>5) survivorship period (72% vs 61% vs 40%, P < .001). A higher percentage of late survivors preferred virtual visits (38% vs 28%, P = .001). In total, 91 (53.2%) respondents sought emotional support outside of immediate family and friends. This included cancer support groups (36.2%), the medical team (29.7%), and other sources outside of these (34.1%), including faith-based organizations and online communities. A higher proportion of women than men (62% vs 41%, P = .001) were seeking emotional support outside of immediate family and friends.
Conclusions
During the early stages of the COVID-19 pandemic, patients with HNC who were actively undergoing treatment had increased need for support resources and preferred in-person provider visits. Alternatively, a higher percentage of patients >5 years from treatment preferred virtual visits. Emotional support outside of family and friends was sought out by a majority of respondents. Further research is needed to determine what support and educational resources are needed to best aid these various populations.
Oropharynx cancer (OPC) incidence has increased for several decades in the US. It is unclear when and how this trend will be affected by current HPV vaccination trends.
To assess the association of ...HPV vaccination with future OPC incidence in the US.
This population-based age-period-cohort analysis obtained OPC incidence data from the Surveillance, Epidemiology, and End Results program from 69 562 patients 34 to 83 years of age diagnosed with OPC. The HPV vaccination data were obtained from the National Immunization Survey-Teen (60 124 participants) and National Health Interview Survey (16 904 participants). Data were collected from January 1, 1992, to December 31, 2017. Age-period-cohort forecasting models projected expected 2018 to 2045 OPC incidence under a counterfactual scenario of no HPV vaccination and current levels of HPV vaccination, stratifying by sex. Data analyses were completed by December 2020.
Age- and sex-specific cumulative prevalence of HPV vaccination in 2016 to 2017 projected forward.
Projected OPC incidence and number of OPC cases expected to be prevented by HPV vaccination.
Under current HPV vaccination rates, between 2018 and 2045, OPC incidence is projected to decrease in younger individuals (36-45 years of age: from 1.4 to 0.8 per 100 000 population; 46-55 years of age: from 8.7 to 7.2 per 100 000 population) but continue to increase among older individuals (70-83 years of age: from 16.8 to 29.0 per 100 000 population). The association of HPV vaccination with overall OPC incidence through 2045 will remain modest (no vaccination vs vaccination: 14.3 vs 13.8 per 100 000 population in 2045). By 2045 HPV vaccination is projected to reduce OPC incidence among individuals 36 to 45 years of age (men: 48.1%; women: 42.5%) and 46 to 55 years of age (men: 9.0%; women: 22.6%), but among those 56 years or older, rates are not meaningfully reduced. Between 2018 and 2045, a total of 6334 OPC cases will be prevented by HPV vaccination, of which 88.8% of such cases occur in younger age (≤55 years) groups.
According to the projections of this population-based age-period-cohort study, current HPV vaccination rates will have a limited association with overall OPC incidence through 2045 because older individuals who have not yet been vaccinated remain at high risk for OPC. However, reductions in OPC incidence should occur among young and middle-aged adults, the group at lowest risk of diagnosis. These findings forecast a continued shift in the landscape of OPC to an older population.
ABSTRACT
Objective
To review recent literature on human papillomavirus‐related (HPV‐positive) oropharyngeal squamous cell carcinoma (OPC) and focus on implications of recurrent and metastatic ...disease.
Methods
Primary articles from 1990 to 2016 indexed in MEDLINE (1) pertaining to the epidemiology of HPV‐positive OPC and (2) providing clinical insight into recurrent and metastatic OPC.
Results
The incidence of HPV‐positive OPC is increasing globally. HPV‐positive OPC is a subtype with distinct molecular and clinical features including enhanced treatment response and improved overall survival. While disease recurrence is less common in patients with HPV‐positive OPC, up to 36% of patients experience treatment failure within eight years. Recurrent and metastatic OPC has historically signified poor prognosis, however recent data are challenging this dogma. Here, we discuss recurrent and metastatic OPC in the context of HPV tumor status.
Conclusion
HPV‐positive OPC exhibits distinct genetic, cellular, epidemiological, and clinical features from HPV‐negative OPC. HPV tumor status is emerging as a marker indicative of improved prognosis after disease progression in both locoregionally recurrent and distant metastatic OPC.

Summary Human papillomavirus (HPV) is responsible for a rising proportion of oropharyngeal squamous cell cancers (OSCCs). HPV-positive OSCCs (HPV-OSCCs) are associated with oral HPV infection and ...sexual behavior. Patient questions regarding risk factors, prognosis and implications for past, present and future relationships often arise. This manuscript addresses frequently asked questions by patients with HPV-OSCC and their families. A framework for clinicians to address these conversations and the limitations of our present knowledge base is also presented.
•Comprehensive review of data regarding treatment de-escalation for HPV-OPSCC.•Two phase III studies have demonstrated inferiority of cetuximab compared to cisplatin.•Phase II data suggest that ...reduced chemoradiation strategies may be feasible.•Several phase II/III treatment de-escalation trials are currently underway.•Treatment de-escalation should be pursued in clinical trials with appropriate patient selection.
Human papillomavirus (HPV)-related oropharyngeal squamous cell cancer (OPSCC) has emerged as a distinct clinical entity of head and neck cancer with expected high survival. This recognition has led to the investigation of whether a population of patients can be identified who can safely undergo treatment de-escalation, in an effort to minimize long-term treatment toxicity while maintaining excellent survival. The purpose of this review is to describe the rationale for treatment deintensification for HPV-related OPSCC, summarize available results from published clinical trials, explore the methods by which risk groups are assigned, and provide context for the multitude of clinical trials that are currently underway.
This perspective highlights a study that reports an increasing proportion of human papillomavirus-positive oropharyngeal cancer among blacks in recent calendar periods. The results are discussed in ...the context of other studies which evaluated racial differences in the distribution of human papillomavirus-positive oropharyngeal cancer and survival.
Highlights • We examine the role of survival bias in relating HPV and timing of recurrence. • A stratified analysis shows how late survivorship is associated with late recurrence. • Late survivors, ...independent of HPV tumor status, may experience late recurrences.
Infections with human papillomavirus (HPV) are common and transmitted by direct contact. Although the great majority of infections resolve within 2 years, 13 phylogenetically related, sexually ...transmitted HPV genotypes, notably HPV16, cause - if not controlled immunologically or by screening - virtually all cervical cancers worldwide, a large fraction of other anogenital cancers and an increasing proportion of oropharyngeal cancers. The carcinogenicity of these HPV types results primarily from the activity of the oncoproteins E6 and E7, which impair growth regulatory pathways. Persistent high-risk HPVs can transition from a productive (virion-producing) to an abortive or transforming infection, after which cancer can result after typically slow accumulation of host genetic mutations. However, which precancerous lesions progress and which do not is unclear; the majority of screening-detected precancers are treated, leading to overtreatment. The discovery of HPV as a carcinogen led to the development of effective preventive vaccines and sensitive HPV DNA and RNA tests. Together, vaccination programmes (the ultimate long-term preventive strategy) and screening using HPV tests could dramatically alter the landscape of HPV-related cancers. HPV testing will probably replace cytology-based cervical screening owing to greater reassurance when the test is negative. However, the effective implementation of HPV vaccination and screening globally remains a challenge.
