Abstract
BACKGROUND An increasing trend of oropharyngeal cancer (OPC) has been reported in several countries with different demographic characteristics, and often attributed to increases in human papillomavirus (HPV) infection. The survival of patients with OPC has steadily improved, especially for those with positive HPV status. This study assessed the incidence, trends, and survival of OPC in Aotearoa New Zealand (NZ) by age at diagnosis, sex and ethnicity. METHODS The study included all 2109 patients resident in NZ with a primary diagnosis of oropharyngeal squamous cell carcinoma from 2006 to 2020, identified from the National Cancer Registry. We assessed age-standardised incidence rate (ASR), annual percent change (APC) and overall and relative survival rates. RESULTS The average annual incidence of OPC was 2.2 per 100,000 population. There was a steady increase of 4.9% per year over 15 years. Although the incidence rates were higher in males over the study period, the overall rate of increase was similar in males (4.9%) and in females (4.3%). The incidence was highest in the 50-69-year group (8.8/100,000 population). This age group had an incidence that increased by 7.5% per year to 2018, and then declined. The main increase in rates was seen between the birth cohort of 1946-50 and that of 1956-60. The increase in incidence was seen in Māori and Pākehā/European populations, but no increase was seen in Pacific or Asian populations. The 5-year overall relative survival rate improved from 69% in 2006-13 to 78% in 2014-20. Survival rates were lower in older patients, females, and Māori patients. CONCLUSION This study confirmed a substantial increase in OPC incidence in NZ, with some evidence to suggest a recent slowing in this increase. Māori and Pākehā/European had the highest incidence, while Pacific and Asian populations showed the lowest rates and no increase over the study period. Survival rates have improved over time, but remained lower in some demographic groups.

Update on the Epidemiological Features and Clinical Implications of Human Papillomavirus Infection (HPV) and Human Immunodeficiency Virus (HIV) Coinfection. Microorganisms 2022; 10:microorganisms10051047. [PMID: 35630489 PMCID: PMC9147826 DOI: 10.3390/microorganisms10051047] [Citation(s) in RCA: 26] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 05/12/2022] [Accepted: 05/17/2022] [Indexed: 12/01/2022] Open
Abstract
Human papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) worldwide. Although most HPV infections will spontaneously resolve, a considerable proportion of them will persist, increasing the risk of anogenital dysplasia, especially within certain populations, such as patients infected with human immunodeficiency virus (HIV). Furthermore, high-risk oncogenic HPV types (HR-HPV) are the main cause of cervix and other anogenital cancers, such as cancer of the vagina, vulva, penis, or anus. HIV and HPV coinfection is common among people living with HIV (PLWH) but disproportionally affects men who have sex with men (MSM) for whom the rate of persistent HPV infection and reinfection is noteworthy. The molecular interactions between HIV and HPV, as well as the interplay between both viruses and the immune system, are increasingly being understood. The immune dysfunction induced by HIV infection impairs the rate of HPV clearance and increases its oncogenic risk. Despite the availability of effective antiretroviral therapy (ART), the incidence of several HPV-related cancers is higher in PLWH, and the burden of persistent HPV-related disease has become a significant concern in an aging HIV population. Several public health strategies have been developed to reduce the transmission of HIV and HPV and mitigate the consequences of this type of coinfection. Universal HPV vaccination is the most effective preventive tool to reduce the incidence of HPV disease. In addition, screening programs for HPV-related cervical and vulvovaginal diseases in women are well-recognized strategies to prevent cervical cancer. Similarly, anal dysplasia screening programs are being implemented worldwide for the prevention of anal cancer among PLWH. Herein, the main epidemiological features and clinical implications of HIV and HPV coinfection are reviewed, focusing mainly on the relationship between HIV immune status and HPV-related diseases and the current strategies used to reduce the burden of HPV-related disease.

Abstract
Incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing globally and the human papillomavirus (HPV) has been linked to this increase. This study aimed to present a comprehensive overview of OPSCC trends in incidence rates by age group and investigate differences in risk factors profile. Netherlands Cancer Registry data from 1989-2018 were analyzed to calculate the annual percentage change (APC) over European standardized incidence rates by gender and age group using joinpoint regression software. Smoking, alcohol drinking and HPV-status were available for 2015-2018. During 1989-2018, 13 048 cases of OPSCC were reported with a male-to-female ratio of 2.1:1. The overall incidence rate increased by 5.4% (APC) annually from 1989 to 1996 but slowed thereafter by 1.2%. Significant declines were found in patients of 35-44 years (APCs -3.7%). Adults aged 45-59 years displayed significant increases from 1989 to 2001, followed by a significant decline. In patients ≥60 years, the incidence rates increased overall, with APC for women being consistently higher than men. The data on HPV status was available for 69% of the patients, of whom 47% were HPV+. Smoking and alcohol consumption were more prevalent, that is 75 and 76 % respectively. The declining trends of OPSCC for Dutch people aged 35-44 years from 1989 to 2018 and for those aged 45-59 years from 2002 onwards are inconsistent to trends reported elsewhere in the developed countries. The prevalence of smoking and drinking alcohol was quite high in all age groups, whereas the proportion of HPV-positivity was relatively low.

Abstract
The aim of this study was to investigate the occurrence, type and severity of anemia at the time of diagnosis of oral cancer, and its potential association with the degree of tumor cell differentiation. This case-control study used 366 medical records of patients treated at two referral centers for oral cancer diagnosis, specifically: cases (n=70) with a histopathological diagnosis of oral squamous cell carcinoma (OSCC) of the oral cavity, and controls (n=296) with benign oral lesions. Sociodemographic, behavioral, and clinical variables of both groups, as well as complete blood count values, were analyzed by descriptive statistics and crude/adjusted logistic regression. Anemia was detected in 15.7% of the cases and 11.8% of the controls. The presence of anemia had an OR=1.64 (odds ratio) (95%CI 0.54-5.00) for OSCC, with no significantly statistical association. Normocytic anemia was the most prevalent form of anemia when oral cancer was diagnosed (91.4% of the controls and 72.7% of the cases), and moderate to severely low hemoglobin levels were associated with OSCC diagnosis (OR 6.49; 95%CI 1.18-35.24), albeit data on hematological examinations were missing.

Abstract
INTRODUCTION Several independent studies report an alarming increase in patients younger than 40 being diagnosed with squamous cell carcinoma. There is currently a lack of available data clearly tracking changes in the age distribution of head and neck cancer (HNC) within the United States. This study attempts to elucidate any trends in oral cavity, oropharynx, larynx and hypopharynx cancer age distribution in the United States population from 1975 to 2016. Unlike previous studies, this paper does not track incidence but rather reports proportional changes of prevalence within age cohorts over time. METHODS This is a retrospective chart review centred on data from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute (NCI). Each decade interval from 1975 to 2016 displays the proportion of HNC patients, classified by primary tumour subsite, within each age cohort. RESULTS Mean age at diagnosis increased for all subsites except oropharynx. Oropharyngeal cancer was the only subsite to show a decrease in the mean age at diagnosis. In addition, oropharyngeal cancer was the only subsite to demonstrate an overall increase in proportional prevalence, largely due to increased incidence in middle-age (40-59 years) patients. Cancers of the oral cavity were the only subset to show a true increase in the proportion of young (0-39 years) patients, but its mean age at diagnosis still increased. When stratifying by gender, the proportion of young patients in female HNC cases is higher than the young male proportion. CONCLUSION Overall, this study demonstrates an increased proportion of older HNC patients that is consistent with the ageing population. Oral cavity cancer demonstrated a true increase in the proportion of young patients, likely due to the increased incidence of young women diagnosed with this cancer. Oropharyngeal cancer was the only subsite to show a decrease in the mean age at diagnosis. The increased proportion of middle-age patients with oropharyngeal cancer likely reflects the increase in HPV-related cancers.

Global incidence trends in head and neck cancer for HPV-related and -unrelated subsites: A systematic review of population-based studies. Oral Oncol 2021; 115:105177.

Abstract
In head and neck cancer (HNC), some subsites are associated with human papillomavirus (HPV) infection, whereas others are unrelated. Although studies have demonstrated the heterogeneity of HPV prevalence worldwide, its impacts on incidence trends in HNC are unknown. This systematic review examined the incidence trends for HPV-related HNC subsites, exploring patterns by geographic region, age group, sex, and race/ethnicity. We searched for publications on PubMed, Embase, and Scopus. Eligible articles included population-based studies that analyzed incidence trends for subsites classified as a proxy for HPV infection in HNC (hereafter referred to as HPV-related subsites). We retrieved 3,948 non-duplicate records, of which 31 were eligible articles, representing 18 countries and spanning almost fifty years. Overall, the incidence of HPV-related HNC subsites rose, while most of the HPV-unrelated subsites declined or remained stable. For HPV-related HNC subsites, incidence trends increased regardless of age group, highlighting a distinct global pattern between sexes. Also, similar peaks in increased risk were observed in recent cohorts from both Australia and the United States. There is a dramatic shift in the global trends of HNCs, characterized by the emerging burden in HNC for HPV-related subsites.

Abstract
BACKGROUND Cancer is one of the diseases causing society's fears as a stigma of death and pain. Head and Neck Squamous Cell Carcinoma (HNSCC) is a group of malignant neoplasms of different locations in this region of the human body. It is one of the leading causes of morbidity and mortality in Brazil, because these malignant neoplasias, in most cases, are diagnosed in late phases. Surgical excision, chemotherapy and radiotherapy encompass the forefront of antineoplastic therapy; however, the numerous side effects associated with these therapeutic modalities are well known. Some treatments present enough potential to help or replace conventional treatments, such as Magnetic Hyperthermia and Photodynamic Therapy. Such approaches require the development of new materials at the nanoscale, able to carry out the loading of their active components while presenting characteristics of biocompatibility mandatory for biomedical applications. OBJECTIVE This work aims to make a bibliographical review of HNSCC treatments. Recent techniques proven effective in other types of cancer were highlighted and raised discussion and reflections on current methods and possibilities of enhancing the treatment of HNSCC. METHOD The study was based on a bibliometric research between the years 2008 and 2019 using the following keywords: Cancer, Head and Neck Cancer, Chemotherapy, Radiotherapy, Photodynamic Therapy, and Hyperthermia. RESULTS A total of 5.151.725 articles were found, 3.712.670 about cancer, 175.470 on Head and Neck Cancer, 398.736 on Radiotherapy, 760.497 on Chemotherapy, 53.830 on Hyperthermia, and 50.522 on Photodynamic Therapy. CONCLUSION The analysis shows that there is still much room for expanding research, especially for alternative therapies since most of the studies still focus on conventional treatments and on the quest to overcome their side effects. The scientific community needs to keep looking for more effective therapies generating fewer side effects for the patient. Currently, the so-called alternative therapies are being used in combination with the conventional ones, but the association of these new therapies shows great potential, in other types of cancer, to improve the treatment efficacy.

Abstract
Simple Summary While previous studies have suggested that HPV-associated head and neck cancer (HNC) is mostly in the younger population, we found that in the last 40 years, the mean age at diagnosis of oropharyngeal cancer has been 60.3 years. We found that after an initially decrease leading up to the early 2000s, there has been a steady increase in age at diagnosis of oropharyngeal cancer since 2002. For non-oropharyngeal HNC, mean age at diagnosis has steadily increased throughout the last four decades. Finally, we found that age at diagnosis of HNC is higher among females in general, and lowest among blacks. Abstract The emergence of the human papillomavirus (HPV) as the primary etiology of oropharyngeal cancer has changed head and neck cancer (HNC) epidemiology. This study described change in the age at diagnosis of oropharyngeal and non-oropharyngeal HNC in the United States in the last four decades. Using a retrospective cohort analysis, the Surveillance, Epidemiology, and End Results dataset from 1975 to 2016 was queried for eligible adult cases of HNC, grouped as oropharyngeal (n = 31,702) versus non-oropharyngeal (n = 87,108). Age at diagnosis was compared by gender (female, male) using independent t-test, and by race/ethnicity (Hispanic, non-Hispanic black, non-Hispanic white, non-Hispanic other) using analysis of variance. Joinpoint regression estimated yearly increases/decreases in age of diagnosis by sex and race/ethnicity through annual percent changes (APC), which were summarized with average annual percent changes (AAPC). Mean age at diagnosis for oropharyngeal cancer was 60.3 years. While there was initially a decrease in age at diagnosis, a 0.37% annual increase occurred from 2002 to 2016 (APC = 0.37, 95% confidence interval (CI) 0.28, 0.45). For non-oropharyngeal cancer, mean age at diagnosis was 63.2 years, with a continuous increase in age at diagnosis throughout the study period (1975–2016 AAPC = 0.08, 95% CI 0.04, 0.12). Females had higher average age at diagnosis than males for both sites, while blacks (57.4 years for oropharyngeal cancer; 59.0 years for non-oropharyngeal) had the lowest age at diagnosis of all races/ethnicity. Age at diagnosis of oropharyngeal cancer has increased significantly since 2002, while non-oropharyngeal HNC has increased significantly in the last four decades.

Abstract
OBJECTIVES We investigated how tonsillectomy during childhood may influence the distribution of human papillomavirus (HPV) positive cancer of the tonsils in adult life using p16 as a surrogate marker for HPV infection. STUDY DESIGN Retrospective observational study. METHODS A total of 280 patients diagnosed with oropharyngeal squamous cell carcinoma (OPSCC) and known p16 status were eligible for this study. Each participant was called to obtain the childhood tonsillectomy history. Respondents were subgrouped by p16 status and the primary tumor location. Patient demographic and clinical information was analyzed for association with Fisher's exact and Wilcoxon rank sum tests. Location of tumor was modeled using univariate (UVA) and multivariate (MVA) logistic regression with associated odds ratios (OR) and 95% confidence intervals. RESULTS Of the 280 patients, 115 (41%) were respondents: 104 (90.4%) were p16 positive and 11 (9.6%) were p16 negative. For p16 positive patients, we observed a majority (93%) of intact tonsils in those with tonsil cancer, compared to 45% of intact tonsils in patients with p16 positive cancer elsewhere in the oropharynx (P < .001). MVA logistic regression showed that female gender (OR = 4.16, P = .0675), prior smoking history (OR = 2.6, P = .0367), and intact tonsils (OR = 15.2, P < .0001) were associated with tonsillar OPSCC. CONCLUSION We found that patients with p16 positive OPSCC at a non-tonsil site were much more likely to have had prior tonsillectomy vs those with p16 positive OPSCC arising within the tonsil. Nevertheless, we do not advocate tonsillectomies as a public health policy to reduce HPV-related OPSCC. LEVEL OF EVIDENCE 6.
