Is 2045 the best we can do? Mitigating the HPV-related oropharyngeal cancer epidemic

Breaking barriers: why including boys and men is key to HPV prevention

Despite the common belief that human papillomavirus (HPV) primarily affects women, it is imperative to recognize and address the impact of HPV on boys and men. Overlooking the health implications for males is a notable gap, as efforts have predominantly focused on preventing HPV-related infections in women. This commentary aims to emphasize the importance of HPV awareness and vaccination for boys and men by highlighting the prevalence and consequences of HPV infection, elaborating on the associated health risks, elucidating the benefits of vaccination, and urging readers to recognize the necessity of protecting males from HPV. In addition, the increase in HPV-related cancers in men underscores the urgent need for increased awareness and vaccination. Although specific testing for HPV in men is not available, the inclusion of men and boys in gender-neutral vaccination programs can help reduce the harmful effects of this virus in both genders.

Perceptions of the role of dentists in human papillomavirus and COVID-19 vaccinations: Results of a cross-sectional validated survey of adults

BACKGROUND

Human papillomavirus (HPV) and COVID-19 are contagious diseases for which effective vaccines exist. Dental care professionals' involvement in vaccination campaigns for these conditions has been proposed, but there is a lack of understanding of dentists' roles in vaccination, specifically assessing patients' attitudes around dentists as vaccinators for HPV and COVID-19.

METHODS

Using a cross-sectional design and convenience sampling, a 12-item validated survey was distributed to community members to determine perceptions about dentists' roles in vaccination for HPV and COVID-19. Demographic characteristics, vaccination status, knowledge of the diseases, vaccination intentions, and willingness to receive education about, recommendations for, and administration of vaccine from a dentist were assessed. Responses were analyzed using bivariate and multivariate analysis.

RESULTS

Of 618 participants, most were vaccinated previously against HPV and COVID-19 (n = 462 [75.6%] and n = 371 [61.0%], respectively). Participants responded more favorably to dentist involvement in educating, discussing, and administering COVID-19 vaccines than HPV vaccines (P < .05). Participants' knowledge of HPV was found to be low compared with that of COVID-19. There were significant differences across demographic groups, with race most frequently associated with differences in responses to COVID-19 and HPV-related questions.

CONCLUSIONS

Formative data to develop interventions to support dentists' participation in vaccination campaigns are provided. Participants' acceptance of COVID-19 vaccination over HPV vaccination may reflect the public awareness of COVID-19 vs HPV due to daily relevance of this disease, or the lack of knowledge about HPV, particularly its oropharyngeal impacts.

PRACTICAL IMPLICATIONS

The authors provide evidence to support dentists' involvement in vaccine education and distribution, expanding previous literature into evaluation of a new disease context (COVID-19). Lack of knowledge of HPV may affect willingness to receive the HPV vaccine, presenting an opportunity for education.

Salvage transoral robotic surgery in recurrent oropharyngeal carcinoma: a single-center retrospective study

PURPOSE

Salvage surgery is still the best therapeutic option for resectable recurrent oropharyngeal squamous cell carcinoma (rOPSCC). Transoral robotic surgery may potentially reduce the morbidity of standard open approaches. The aim of the study is to present oncological and functional outcomes of a monocentric experience in salvage transoral robotic surgery.

METHODS

We performed a single-center retrospective analysis of patients submitted to transoral robotic salvage surgery with or without neck dissection for cT1-3 rOPSCC. We investigated complication rate, survival outcomes (Overall Survival, Disease Specific Survival, Loco-Regional Recurrence Free Survival) and functional outcomes (tracheal tube and/or gastrostomy dependence).

RESULTS

Sixty-one patients were included in the analysis. No major complications or perioperative deaths were recorded. The estimated 2-year OS was 76.7%, DSS 81.8% and LRRFS 50.5%. In multivariable analysis rpT, PNI (perineural infiltration) and HPV-positivity were significantly associated with LRRFS (Hazard Ratios: T3 vs T1 6.43, PNI yes vs no 4.19, HPV+ yes vs no 2.63). At last follow up, 97% of patients were tracheal tube-free, while 93% were gastrostomy-free.

CONCLUSION

Transoral robotic salvage surgery is a successful treatment in selected patients affected by rOPSCC because it grants good oncologic and functional outcomes.

Combining the radiomics signature and HPV status for the risk stratification of patients with OPC

OBJECTIVE

The objective was to perform risk stratification of oropharyngeal cancer (OPC) for treatment de-escalation based on the radiomics analysis and human papillomavirus (HPV) status.

METHODS

A total of 265 patients with OPC who underwent baseline contrast-enhanced computed tomography were analyzed, and the patients were grouped into the training (n = 133) and test (n = 132) cohorts at a ratio of 1:1. Intratumoral and peritumoral radiomics features were extracted, and the radiomics signature (Rscore) was calculated using least absolute shrinkage and selection operator regression (LASSO) and Cox regression analyses.

RESULTS

Twelve features were selected to establish the radiomics signature (Rscore) of intratumoral regions +10-mm peritumoral regions, which yielded maximum AUCs of 0.835, 0.798, and 0.784 in the training, test, and validation cohorts, respectively. Patients with OPC were divided into the high-risk group, intermediate-risk group, and low-risk group based on the Rscore and HPV status and had different prognoses. Patients in the low-risk group benefit from radiotherapy alone, and patients in the intermediate-risk group only benefitted from chemoradiotherapy.

CONCLUSION

The radiomics signature appears to improve the predictive performance of clinical characteristics for oropharyngeal cancer. The combined stratification of the radiomics signature and HPV status might be preferred to select patients for de-escalated treatment.

Oral healthcare providers play a vital role in vaccination efforts: Patient perspectives

OBJECTIVES

Human papillomavirus (HPV) is associated with 70% of oropharyngeal squamous cell carcinomas. Coronavirus disease 2019 (COVID-19) is the infectious cause of a global pandemic that killed millions worldwide. Effective vaccinations exist against both diseases, but patient acceptance remains a challenge. The objective of this study was to assess patients' attitudes toward oral healthcare providers' (OHCPs) roles in HPV and COVID-19 vaccinations.

METHODS

A cross-sectional survey of young adult patients was distributed in Philadelphia, PA, between April and June 2021. The survey assessed knowledge and attitudes around OHCPs serving various roles in COVID-19 and HPV vaccination.

RESULTS

Nearly 70% of 163 respondents would accept the recommendation for a COVID-19 vaccine from an OHCP, while 56% would for HPV. Those previously vaccinated against COVID-19 were more comfortable discussing COVID-19 vaccines (92%, p < .001) or HPV vaccines (76%, p < .001) with OHCPs compared to those who were unvaccinated against COVID-19. African American/Black patients were less comfortable discussing vaccines, irrespective of vaccination status.

CONCLUSIONS

OHCP can play a vital role in increasing the overall COVID-19 and HPV vaccination status of the public, as demonstrated by the high acceptance of dental involvement in both vaccine campaigns. Racial disparity in vaccination attitude is a public health challenge that needs to be addressed.

Assessing the capacity of methylated DNA markers of cervical squamous cell carcinoma to discriminate oropharyngeal squamous cell carcinoma in human papillomavirus mediated disease

OBJECTIVE

Early identification of human papillomavirus associated oropharyngeal squamous cell carcinoma (HPV(+)OPSCC) is challenging and novel biomarkers are needed. We hypothesized that a panel of methylated DNA markers (MDMs) found in HPV(+) cervical squamous cell carcinoma (CSCC) will have similar discrimination in HPV(+)OPSCC tissues.

MATERIALS AND METHODS

Formalin-fixed, paraffin-embedded tissues were obtained from patients with primary HPV(+)OPSCC or HPV(+)CSCC; control tissues included normal oropharynx palatine tonsil (NOP) and cervix (NCS). Using a methylation-specific polymerase chain reaction, 21 previously validated cervical MDMs were evaluated on tissue-extracted DNA. Discrimination between case and control cervical and oropharynx tissue was assessed using area under the curve (AUC).

RESULTS

34 HPV(+)OPSCC, 36 HPV(+)CSCC, 26 NOP, and 24 NCS patients met inclusion criteria. Within HPV(+)CSCC, 18/21 (86%) of MDMs achieved an AUC ≥ 0.9 and all MDMs exhibited better than chance classifications relative to control cervical tissue (all p < 0.001). In contrast, within HPV(+)OPSCC only 5/21 (24%) MDMs achieved an AUC ≥ 0.90 but 19/21 (90%) exhibited better than chance classifications relative to control tonsil tissue (all p < 0.001). Overall, 13/21 MDMs had statistically significant lower AUCs in the oropharyngeal cohort compared to the cervical cohort, and only 1 MDM exhibited a statistically significant increase in AUC.

CONCLUSIONS

Previously validated MDMs exhibited robust performance in independent HPV(+)CSCC patients. However, most of these MDMs exhibited higher discrimination for HPV(+)CSCC than for HPV(+)OPSCC. This suggests that each SCC subtype requires a unique set of MDMs for optimal discrimination. Future studies are necessary to establish an MDM panel for HPV(+)OPSCC.
