Pan-American prevalence of smokeless tobacco use and association with oral potentially malignant disorders and head and neck cancer: a systematic review and meta-analysis

OBJECTIVES

To determine the prevalence of smokeless tobacco (SLT) use and its association with oral potentially malignant disorders (OPMDs) and head and neck cancer (HNC) in the Pan-American Health Organization (PAHO) region.

STUDY DESIGN

A literature search was conducted across 9 databases and other sources. The eligibility criteria were pediatric (0-18 years old) and adult (19 years and older) populations consuming any type of SLT. Meta-analysis was performed to determine the prevalence of SLT and the association between its use and OPMDs/HNC in the PAHO region; the Grading of Recommendations Assessment, Development, and Evaluation tool was used to verify the certainty of evidence.

RESULTS

Fifty-nine studies from 6 PAHO countries were included, of which 51 were also subjected to quantitative analysis. The pooled SLT prevalence of use was 15% (95%CI: 11.93-18.69) overall, 17% (95%CI: 13.25-22.65) in adults, and 11% (95%CI: 8.54-14.78) in the pediatric population. The highest reported SLT prevalence of use was 33.4% (95%CI: 27.17-39.93) in Venezuela. HNC was positively associated with SLT use (OR = 1.98, 95%CI: 1.54-2.55), with a moderate certainty of evidence. Among OPMDs, only leukoplakia reported a positive association with SLT use (OR = 8.38; 95%CI: 1.05-67.25). However, the quality of the evidence was very low.

CONCLUSION

A high consumption of SLT use, chewing tobacco and snuff, is reported among the adult population residing in the PAHO region with a positive association with the development of oral leukoplakia and HNC.

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.

Sexual health at 5 years after diagnosis of head and neck cancer

PURPOSE

Sexual health (SH) is an emerging concern in the assessment of quality of life in patients surviving head and neck cancer (HNC). Using data from the French National Prospective VICAN Survey, this study aimed to assess SH deterioration five years after HNC diagnosis and related factors.

METHODS

Using univariate and multivariate analyses were performed in the 241 HNC survivors. We studied the factors associated between the sexuality and intimate life of these patients with demographic and medical data from the national epidemiological survey VICAN 5.

RESULTS

Sexuality and body image were altered in 78.8% for men and 79.2% for women. This alteration in sexual quality of life affects both men and women. Dissatisfaction with the frequency of sexual intercourse was associated with being treated with radiotherapy (p=0.024), as well as decrease of sexual desire in patients treated with chemotherapy (p=0.044). Fatigue (p=0.002), impaired physical health (p=0.049), and high disease stage (p=0.001) remained significantly associated, after multivariate analysis, with decreased sexual desire. Among these 3 factors negatively influencing sexual quality of life, two are treatable with appropriate management.

CONCLUSION

Five years after the diagnosis of HNC, a decrease in sexuality and body image are frequent and significantly impact the quality of life of survivors. These observations imply an adaptation of the management of the professionals involved.

Patient delay and its clinical significance among head and neck cancer patients in Hungary

Introduction: Head and neck cancers represent a major health problem in Hungary. With their high incidence and mortality rates, Hungary is one of the world leaders in these indicators. The length of patient delay, defined as time from onset of symptoms to first medical consultation, is unknown in Hungarian patients with head and neck cancer. We aimed to use a representative sample of the Hungarian head and neck cancer patient population to determine patient delay according to disease localization and stage and to identify correlations with other clinical parameters. Methods: In our retrospective study, we reviewed patient documentation. For the inclusion, the patients had to be diagnosed with malignant tumors of the oral cavity, oropharynx, hypopharynx or larynx at the Department Head and Neck Surgery of Semmelweis University between 2012 and 2017. Results: We identified 236 patients who met the inclusion criteria. The median delay was 9.5 weeks (range 0-209 weeks) and the mean delay of patients was 17.57 weeks (SD 23.67). There was a significant difference in patient delay data by location. Among glottic cancers, the most common diagnosis was an early stage (67%), compared with other localizations, including most commonly the oropharynx (81%) and hypopharynx (80%), where a locoregionally advanced stage was more frequent. Discussion: Compared to data from different countries, the delay of Hungarian patients with head and neck cancer is significantly longer, which may contribute to the high mortality in Hungary. Screening and patient education in high-risk groups could contribute to earlier diagnosis and thus improve prognosis.

Awareness of head and neck cancer among patients attended at a regional referral hospital in Tanzania

BACKGROUND

Head and neck cancers (HNCs) are considered to be lethal and about 50% of the cases are diagnosed at advanced stages and are associated with poor prognosis. Despite the high disease burden globally, there are scarce studies on awareness of HNCs and this is the first study to explore such awareness in Tanzania. The study aimed at determining awareness of head and neck cancer among patients attended at a regional referral hospital in Tanzania.

METHODS

A hospital based cross sectional study was conducted at Geita Regional Referral Hospital from April to May 2022 where 315 respondents were recruited. Simple random sampling technique was utilized and data was collected using structured questionnaires and analyzed using Statistical Package for Social Sciences (SPSS) version 23. Chi-square test was performed to establish the relationship between the selected independent and dependent variables. P-value < 0.05 was considered to be statistically significant.

RESULTS

More than half (54.9%) of the respondents considered themselves to be somewhat knowledgeable on head neck cancer. In the same study, 56.2% of the respondents didn't know anatomical sites of head and neck cancer and over half (65.9%) of the respondents didn't know signs and symptoms of head and neck cancer. Cigarette smoking (73.7%) and alcohol consumption (65.1%) were the most correctly identified risk factors for HNCs. Regarding treatment options and preventive measures, 75.2% of the respondents knew cessation of cigarette smoking as a preventive measure for HNCs and surgery (91.7%) was the most known treatment option for head and neck. Similarly, a significant association was found between awareness on HNCs and some of the socio-demographic characteristics of the respondents.

CONCLUSIONS

Although majority of respondents considered themselves to be somewhat knowledgeable on HNCs, awareness by patients on anatomical sites, clinical features, risk factors, preventive measures and curability of head and neck cancer at the Regional Referral Hospital was minimal.

Missed cancer in the Danish head and neck cancer fast-track program: results from a tertiary cancer center

BACKGROUND

The Danish head and neck cancer fast-track program is a national standardized pathway aiming to reduce waiting time and improve survival for patients suspected of cancer in the head and neck (HNC). Until now, the frequency of missed cancer in the fast-track program has not been addressed. A missed cancer leads to treatment delay and may cause disease progression and worsening of prognosis. The study objective was to estimate the frequency of patients with missed cancers in the Danish HNC fast-track program and to evaluate the accuracy of the program.

MATERIALS AND METHODS

Patients who were rejected from the HNC fast-track program because cancer was not found between 1 July 2012 and 31 December 2018 at Odense University Hospital, Denmark were included and followed for three years. Patients were categorized into groups depending on the diagnostic evaluation. Group 1 included patients evaluated with standard clinical work-up without imaging and biopsy. Group 2 included patients evaluated with imaging and/or biopsy in addition to the standard clinical work-up. The local cancer database and electronic patient records were reviewed to determine if a missed cancer had occurred within the follow-up period.

RESULTS

A total of 8345 HNC fast-track courses were initiated during the study period. 1499 were patients suspected of recurrent cancer and were excluded leaving 6846 patients to be assessed for eligibility. Of these, 3752 patients were rejected because cancer was not found. Ten patients were subsequently diagnosed with cancer within the follow-up period resulting in an overall frequency of 0.15%. For group 1 and 2, the frequency was 0.04% and 0.10%, respectively. The sensitivity of the fast-track program was 99.67% and the negative predictive value was 99.73%.

CONCLUSION

The frequency of missed cancer in a tertiary HNC center following the Danish fast track program is low.

Examining the effect of Medicaid expansion on early detection of head and neck cancer of the oral cavity and pharynx by HPV-type and generosity of dental benefits

BACKGROUND

Over a decade of evidence supports the claim that increased access to insurance through Medicaid expansions improves early detection of cancer. Yet, evidence linking Medicaid expansions to early detection of head and neck cancers (HNC) of the oral cavity and pharynx, specifically, may be limited by the lack of attention to Human Papillomavirus (HPV) etiology, generosity of dental coverage, and valid inference analyzing state cancer registry data.

AIMS

This study reexamined the effect of Medicaid expansion on early detection of HPV+/- HNC in states offering extensive dental benefits.

MATERIALS AND METHODS

Specialized data from the Surveillance, Epidemiology, and End Results (SEER) program was analyzed to account for, previously unmeasurable, differential detection patterns of HNCs associated with HPV. Then, to identify the effect of increasing Medicaid eligibility on staging patterns in states offering extensive benefits amidst potentially non-common trends between states, a "Triple Differences" design identifies the differential effect of Medicaid Expansion (with dental coverage) on HPV-negative HNCs relative to the change in HPV-positive HNCs. For valid inference analyzing a small number of state clusters (12) in cancer registry data, each regression model applies a Wild Cluster Bootstrap.

RESULTS

Expanding Medicaid eligibility was found to be associated with a decrease in the proportion of distant-stage diagnoses of HPV(-) HNCs, but only among states which increased Medicaid dental generosity at the time of Medicaid expansion.

CONCLUSIONS

These results suggest that adding extensive Medicaid dental benefits was the primary mechanism impacting HNC detection. This study highlights the potential positive spillover effects of policies which increase access to public dental coverage for low-income adults, while also showing the limitation of access to dental services for improving early detection of HPV+ HNCs.

Awareness about Tobacco Causing Head and Neck Cancers via Mass Media: A Case-Control Study from India

OBJECTIVE

This study aimed to assess the awareness of people about the adverse effects of tobacco (smoking and chewing) consumption causing head and neck cancers (HNCs) via mass media channels like television, cinema, radio and newspapers or magazines, wall painting or billboards / hoardings, public transportation and packets of chewing tobacco, bidis or cigarettes.

METHODS

Hospital-based case-control was conducted in Pune, Maharashtra, India. Face to face interviews were conducted for the purpose of data collection on 225 cases and 240 controls. The relationship between two categorical variables were estimated using chi-square test with a  2-tailed P value of <.05.  SPSS software was used for data analysis.

RESULTS

Controls as compared to cases had good awareness scores for chewing (59.9%) and smoking tobacco (63.7%), P<0.001. The most common form of mass media was television where the cases (60.4%) and controls (77.9%) had heard messages about tobacco in chewing and smoking form causing HNCs. Level of awareness of tobacco causing HNCs amongst tobacco users, stratified by their status (cases versus controls) showed that cases were 1.68 times less likely than controls to have heard or seen messages about the association between chewing tobacco and HNCs via radio. Males (61.3% and 61.0%) had significantly (P<0.001) more awareness as compared to females (46.9% and 43.5%) about chewing and smoking tobacco as a causal factor for  HNCs.

CONCLUSION

Mass media needs to create a social environment which discourages tobacco consumption and promotes oral health at the population level. Additionally, there should be easy access to the availability of support services like Quitline and other community support services.

Epidemiology and demographics of head and neck cancer in Africa: A scoping review

BACKGROUND

Low- to middle-income countries account for 70% of global cancer deaths. Evidence of the changing prevalence of head and neck cancer in Africa in terms of gender, race and epidemiology will inform future research and health planning.

AIM

To synthesise epidemiological literature for head and neck cancer in Africa from 2010 to 2020.

METHOD

A scoping review was completed. The Joanna Briggs Institute Population, context and concept framework confirmed the inclusion criteria. Studies from Africa that included participant demographics, the types, stages, signs and symptoms of head and neck cancer were selected. Five databases were used. Descriptive statistics was completed.

RESULTS

The Preferred Reporting Items for Systematic Reviews and MetaAnalysis guided the reporting of the findings. Of the 1891 articles downloaded, 66 were included in the final review. Nigeria produced the most studies and oral cancer at 74% was most prevalent. Substance abuse was the most prevalent cause. Diagnosis of head and neck cancers were in the late stage (stage IV) when signs and symptoms were severe. Males of lower socioeconomic status tended to have less health seeking behaviour.

CONCLUSION

Countries from North Africa produce the most research outputs on head and neck cancers. Gender differences were noted and may be linked to lifestyle choices. A range of head and neck cancers (HNCs) are prevalent however late diagnosis and severe symptomatology impact treatment options.Contribution: Earlier diagnosis and intervention to prevent late-stage diagnosis is necessary. Awareness campaigns linked to evidence on causes, habits and lifestyle choices, signs and symptoms are needed.

Risk of Cardiovascular Events Among Patients With Head and Neck Cancer

Importance

Cardiovascular (CV) disease is a substantial cause of morbidity and mortality in cancer due to shared risk factors and exposure to potentially cardiotoxic cancer therapy. However, our understanding of CV risk in patients with head and neck squamous cell carcinoma (HNSCC) is limited.

Objective

To define CV risk profiles, incident stroke, myocardial infarction (MI), and mortality in patients with HNSCC.

Design, Setting, and Participants

This retrospective, population-based cohort study included 35 897 US veterans with newly diagnosed HNSCC from January 1, 2000, to December 31, 2020. Data were analyzed from May 2022 to January 2023.

Exposures

Demographic, cancer-specific, and treatment characteristics.

Main Outcomes

Prevalence of CV risk factors, medication use, and control at HNSCC diagnosis; cumulative incidence of stroke and MI; and all-cause death.

Results

Of 35 857 US veterans with HNSCC (median [IQR] age, 63 [58-69] years; 176 [0.5%] American Indian or Alaska Native, 57 [0.2%] Asian, 5321 [16.6%] Black, 207 [0.6%] Native Hawaiian or Other Pacific Islander, and 26 277 [82.0%] White individuals), there were high rates of former or current smoking (16 341 [83%]), hypertension (24 023 [67%]), diabetes (7988 [22%]), and hyperlipidemia (18 421 [51%]). Although most patients were taking risk-lowering medications, 15 941 (47%) had at least 1 uncontrolled CV risk factor. Black race was associated with increased risk of having uncontrolled CV risk factor(s) (relative risk, 1.06; 95% CI, 1.03-1.09), and patients with larynx cancer had higher rates of prevalent and uncontrolled risk factors compared with other cancer subsites. Considering death as a competing risk, the 10-year cumulative incidence of stroke and MI was 12.5% and 8.3%, respectively. In cause-specific hazards models, hypertension, diabetes, carotid artery stenosis, coronary artery disease, and presence of uncontrolled CV risk factor(s) were significantly associated with stroke and MI. In extended Cox models, incident stroke and MI were associated with a 47% (95% CI, 41%-54%) and 71% (95% CI, 63%-81%) increased risk of all-cause death, respectively.

Conclusion

The results of this cohort study suggest that in HNSCC, the burden of suboptimally controlled CV risk factors and incident risk of stroke and MI are substantial. Modifiable CV risk factors are associated with risk of adverse CV events, and these events are associated with a higher risk of death. These findings identify populations at risk and potentially underscore the importance of modifiable CV risk factor control and motivate strategies to reduce CV risk in HNSCC survivorship care.

Pattern of metastasis of head and neck cancer in Nigeria: A 10 year review

Introduction

Head and neck cancer is a common and aggressive malignancy with a high morbidity and mortality profile that occur in several anatomical sites in the head and neck region. They constitute the tenth most common cancer in the world. Metastatic head and neck cancers are associated with severe morbidities and its treatment is mainly palliative. This study examined the patterns of metastases of head and neck cancer in patients in a tertiary hospital in Nigeria.

Method

The data extraction form was used to obtain information from the Radiotherapy treatments records and the case notes of patients with histological diagnosis of Head and Neck Cancers between 2002 and 2011 at the Radiotherapy department, University College Hospital, Ibadan. Analyses was done using statistical Package for Social Sciences (SPSS) Version 20.0.

Results

A total of 481 patients were seen in this study. The age of the patients ranged from 11 years to 80 years with mean age of 42 years. The male to female ratio was 2:1. The peak age of incidence was between 40-49 years. Most patients presented with stage III and IV. Nasopharyngeal carcinoma had the highest proportion of occurrence 205 (42.6%) followed by paranasal sinuses. Lung had the commonest site of metastasis followed by bones.

Conclusion

More than half of the patients presented late with the commonest cancer being nasopharyngeal carcinoma. Lung was the commonest site of distant metastasis with nasopharyngeal carcinoma having the highest proportion of metastasis to the lungs at two years follow up.

Oral Premalignant and Malignant Lesions in Fanconi Anemia Patients

OBJECTIVE

There is a lack of data supporting cancer surveillance in pediatric Fanconi Anemia patients. We sought to describe the rates of upper aerodigestive lesions and malignancy in this population to augment current management guidelines.

METHODS

A retrospective cohort study of patients with Fanconi Anemia from a quaternary referral center between 2007-2021 was completed for head and neck cancer risk.

RESULTS

One hundred and five FA patients were reviewed. Average age at presentation was 11.3 years old and 90.5% of patients underwent hematopoietic stem cell transplant (HSCT). A total of 8.6% of patients had leukoplakia or erythroplakia and 3.8% developed malignancy. The standardized incidence ratio of head and neck malignancy was 483.8. Patients presented with leukoplakia and malignancy at an average age of 14.6 and 25.1 years old, respectively. Malignancies were aggressive and marked by recurrence. There were no premalignant or malignant lesions found on flexible laryngoscopy. This series represents the largest longitudinal series of pediatric FA head and neck lesions.

CONCLUSIONS

Fanconi Anemia patients should begin screening for head and neck cancer at age 10 or after HSCT.

LEVEL OF EVIDENCE

Level 4 Laryngoscope, 133:1745-1748, 2023.

Quad-shot-immunotherapy: quad-shot radiotherapy with pembrolizumab for advanced/recurrent head and neck cancer

Effective treatments for advanced/recurrent head and neck squamous-cell carcinoma are limited. For cases not curable by conventional local therapies, the immune checkpoint inhibitor pembrolizumab shows modest response rates. Quad-shot, a hypofractionated palliative radiotherapy regimen (14.8 Gy in four twice-daily fractions), can provide symptomatic relief, contributes to local control and may potentiate the effects of immune checkpoint inhibitors. In this study, 15 patients with advanced/recurrent head and neck squamous-cell carcinoma will be treated with pembrolizumab combined with up to three administrations of quad-shot before cycles four, eight and 13. Outcomes include disease response, survival and treatment toxicity. Correlative multiomics analysis of blood and saliva will identify molecular biomarkers of response to immune checkpoint inhibitor and the immune-related impact of quad-shot. Clinical trial registration: This study (WFBCCC 60320) is registered on NCT04454489 (ClinicalTrials.gov).

A nationwide study on cancer recurrences, second primary tumours, distant metastases and survival after treatment for primary head and neck cancer in the Netherlands

INTRODUCTION

There is no consensus on the optimal duration of post-treatment follow-up after head and neck cancer (HNC). To generate site-specific input for follow-up guidelines, this study describes the incidence and timing of manifestations of disease during five years of follow-up.

METHODS

All patients diagnosed with HNC in the Netherlands in 2015 were selected from the Netherlands Cancer Registry. The follow-up events local recurrence (LR), regional recurrence (RR), second primary tumour (SPT), distant metastasis (DM) and death were studied per follow-up-year. The cumulative incidence of these events was calculated using competing risk analyses, with LR, RR and SPT of the head and neck (SPHNC) as events and SPT outside the head-neck (SPOHN), DM and death as competing events. Analyses were performed for oral cavity-, oropharynx-, larynx- and hypopharynx squamous cell carcinoma (SCC), and all HNC patients.

RESULTS

The 1-, 1.5-, and 2-year cumulative incidence of an event (LR, RR, SPHNC) were 10% (95%CI 8-13), 12% (95%CI 10-15), and 13% (95%CI 10-16) for oral cavity SCC; 6% (95%CI 4-9), 10% (95%CI 7-14), and 11% (95%CI 8-15) for oropharynx SCC; 7% (95%CI 5-10), 11% (95%CI 9-15), and 13% (95%CI 10-16) for larynx SCC and 11% (95%CI 6-19), 19% (95%CI 12-27), and 19% (95%CI 12-27) for hypopharynx SCC.

CONCLUSIONS

One year of follow-up for oral cavity SCC, and 1.5 years for oropharynx-, larynx-, and hypopharynx SCC suffices for the goal of detecting disease manifestations after treatment. More research into other aspects of follow-up care should be performed to determine the optimal follow-up regimen.

Health behaviors among head and neck cancer survivors

PURPOSE

To determine to what extent head and neck cancer (HNC) survivors participate in health behaviors (HBs) recommended by the National Cancer Center Network (NCCN®).

METHODS

Participants identified through the tumor registries at the Abramson Cancer Center (ACC), University of Pennsylvania and affiliated sites. Eligibility: (a) diagnosis and treatment HNC; (b) aged 18 to 70 years; (c) ≥ 1-year post-diagnosis; (d) human papillomavirus (HPV) status confirmed; (e) ability to understand written English. Potential participants received an explanation of the study, informed consent, self-reported questionnaire, and self-addressed stamped envelope.

RESULTS

451 individuals eligible, 102 (23%) agreed to participate, HPV positive (74%). Current smoking rare (7%), historical use common (48%). Current alcohol use common (65%), average 2.1 drinks/day, 12 days/month. 22% binge drank with an average of 3.5 binge-drinking sessions per month. Nutritional behavior mean 7.1 (range 0-16), lower scores indicating better nutrition. Body mass index (BMI) 59% overweight/obese. Adequate aerobic exercise 59%, adequate strength and flexibility 64%. Leisure time activity, 18% sedentary, 19% moderately active, 64% active. All participants reported having a primary care physician, 92% seen in the previous 12 months.

CONCLUSIONS

Most HNC survivors participated in some HBs. Current smoking rarely reported, binge drinking and high BMI most common negative HBs. Opportunities remain to improve dietary and exercise behaviors.

IMPLICATIONS FOR CANCER SURVIVORS

The NCCN® has outlined HBs that decrease likelihood of cancer survivors developing comorbidities that could impact overall survival. It is incumbent on healthcare providers to educate and encourage cancer survivors to participate in these HBs.

Risk factors for head and neck cancer in more and less developed countries: Analysis from the INHANCE consortium

OBJECTIVE

We analyzed the pooled case-control data from the International Head and Neck Cancer Epidemiology (INHANCE) consortium to compare cigarette smoking and alcohol consumption risk factors for head and neck cancer between less developed and more developed countries.

SUBJECTS AND METHODS

The location of each study was categorized as either a less developed or more developed country. We compared the risk of overall head and neck cancer and cancer of specific anatomic subsites associated with cigarette smoking and alcohol consumption. Additionally, age and sex distribution between categories was compared.

RESULTS

The odds ratios for head and neck cancer sites associated with smoking duration differed between less developed and more developed countries. Smoking greater than 20 years conferred a higher risk for oral cavity and laryngeal cancer in more developed countries, whereas the risk was greater for oropharynx and hypopharynx cancer in less developed countries. Alcohol consumed for more than 20 years conferred a higher risk for oropharynx, hypopharynx, and larynx cancer in less developed countries. The proportion of cases that were young (<45 years) or female differed by country type for some HNC subsites.

CONCLUSION

These findings suggest the degree of industrialization and economic development affects the relationship between smoking and alcohol with head and neck cancer.

Primary diffuse large B-cell lymphoma of the head and neck in a Brazilian single-center study

OBJECTIVES

Lymphomas represent around 10% of head and neck neoplasms, among which the diffuse large B-cell lymphoma (DLBCL) is the most common histologic subtype. In the present study, we characterized demographic parameters, anatomical sites, and survival rates of patients in a Brazilian cancer center.

MATERIALS AND METHODS

Single-center retrospective epidemiological study of 243 head and neck DLBCL patients. Demographic characteristics, tumor localization, HIV status, lactate dehydrogenase (LDH) activity, and treatment modality were obtained from electronic medical records.

RESULTS

The most common primary head and neck tumor location in patients with DLBCL was Waldeyer's ring. Interestingly, age above 80 years, male gender, high LDH levels, and HIV positivity were significantly associated with shorter overall survival (OS) rates and increased risk of death. We further demonstrated that treatment had a protective effect, improving OS, and reducing risk of death. Notably, we found no benefit of combination of chemotherapy and radiotherapy versus isolated treatment modalities.

CONCLUSION

The study showed that primary head and neck DLBCL is more incident in middle age and elderly patients with a small male patients' majority in a Brazilian population. Moreover, we observed a 3-year OS rate of almost 60% and multivariate analysis showed that treatment was the only protective factor.

Early detection of mandible osteoradionecrosis risk in a high comorbidity veteran population

OBJECTIVE

Osteoradionecrosis (ORN) of the mandible is a devastating complication of external beam radiation therapy (EBRT) for head and neck squamous cell carcinoma (HNSCC). We sought to ascertain ORN risk in a Veteran HNSCC population treatment with definitive or adjuvant EBRT and followed prospectively.

STUDY DESIGN

Retrospective analysis of prospective cohort.

SETTING

Tertiary care Veterans Health Administration (VHA) medical center.

METHODS

Patients with HNSCC who initiated treatment at the Michael E. DeBakey Veterans Affairs Medical Center (MEDVAMC) are prospectively tracked for quality of care purposes through the end of the cancer surveillance period (5 years post treatment completion). We retrospectively analyzed this patient cohort and extracted clinical and pathologic data for 164 patients with SCC of the oral cavity, oropharynx, larynx, and hypopharynx who received definitive or adjuvant EBRT (2016-2020).

RESULTS

Most patients were dentate and 80 % underwent dental extractions prior to EBRT of which 16 (16 %) had complications. The rate of ORN was 3.7 % for oral cavity SCC patients and 8.1 % for oropharyngeal SCC patients. Median time to ORN development was 156 days and the earliest case was detected at 127 days post EBRT completion. All ORN patients were dentate and underwent extraction prior to EBRT start.

CONCLUSION

ORN development can occur early following EBRT in a Veteran population with significant comorbid conditions but overall rates are in line with the general population. Prospective tracking of HNSCC patients throughout the post-treatment surveillance period is critical to early detection of this devastating EBRT complication.

Impact of the COVID-19 pandemic on head and neck cancer patients: systematic review and meta-analysis

OBJECTIVES

This manuscript presents a systematic review of the impact of the COVID-19 pandemic on head and neck cancer (HNC) patients. A meta-analysis was made to compare the number of treated/operated HNC patients in pre-COVID-19 era (PCE) versus COVID-19 era (CE). This investigation is based on previous reports showing a delay in the diagnosis and treatment of new cases of cancer during the pandemic. Worsening in cancer prognosis would be expected as a result of the delayed treatments.

METHOD AND MATERIALS

An electronic search was conducted using the PubMed/MEDLINE, Embase, Web of Science, Scopus and The Cochrane Library databases. Relevant articles were selected based on specific inclusion criteria.

RESULTS

A total of 8942 HNC patients were included. A higher prevalence in male (1873) in comparison to female (1695) was observed considering 3568 patients. Regarding staging, the majority of cases were stage III-IV. The treatment type more frequently described was surgery. Positive diagnosis for COVID-19 in the pre oncologic treatment was reported for 242 patients, and for post oncologic treatment in 119 patients. Mortality by COVID-19 was reported for 27 HNC patients. The meta-analysis revealed a significantly smaller number of surgeries/oncologic treatments of HNC patients performed (2666) in the CE when compared to PCE (3163) (M-H OR = 0.81, 95% CI = 0.65 to 1, P = 0.05).

CONCLUSION

The impact of the COVID-19 pandemic on HNC patients occurred mainly in the number of surgeries/oncologic treatments, showing a significantly smaller number of surgeries/oncologic treatments performed in the CE rather than the PCE.

Differences in risk factors for head and neck cancer among men and women in Nepal: A case-control study

BACKGROUND

Head and neck cancer (HNC) is a major cause of cancer morbidity and mortality in Nepal. The study aims to investigate differences in risk factors for head and neck cancer by sex in Nepal.

METHODS

A hospital-based case-control study was conducted at the B.P. Koirala Memorial Cancer Hospital in Nepal from 2016 to 2018. A semi-structured questionnaire consisting of socio-demographic characteristics, dietary habits, reproductive factors, household air pollution, tobacco use (smoking and chewing), alcohol consumption, and second-hand smoking was used to collect the data. Odds ratios (OR) and 95 % confidence intervals (CI) were estimated using unconditional logistic regression adjusting for potential confounders.

RESULTS

A total of 549 HNC cases (438 men and 111 women) and 601 age-matched healthy controls (479 men and 122 women) were recruited in this study. An increased risk of HNC for low education level and family income were observed among men (adjusted odds ratio (AOR) for 3rd grade and less= 1.58, 95 % CI= 1.14-2.18; AOR for family monthly income < 5000 Rupees = 1.64, 95 % CI 1.20-2.24). The AORs among women were higher than the men for known risk factors (AOR for smoking 1.34 (95 % CI 0.96-1.86) for men, 2.94 (95 % CI 1.31-6.69) for women; AOR for tobacco chewing 1.76 (95 % CI 1.27-2.46) for men, 10.22 (95 % CI 4.53-23.03) for women).

CONCLUSION

Our results point to an effect modification by sex for HNC risk factors with high AORs observed among women.

Oral microbiome and risk of incident head and neck cancer: A nested case-control study

OBJECTIVES

This nested case-control study in the NIH-AARP Diet and Health Study was carried out to prospectively investigate the relationship of oral microbiome with head and neck cancer (HNC).

MATERIALS AND METHODS

56 incident HNC cases were identified, and 112 controls were incidence-density matched to cases. DNA extracted from pre-diagnostic oral wash samples was whole-genome shotgun metagenomic sequenced to measure the overall oral microbiome. ITS2 gene qPCR was used to measure the presence of fungi. ITS2 gene sequencing was performed on ITS2 gene qPCR positive samples. We computed taxonomic and functional alpha-diversity and beta-diversity metrics. The presence and relative abundance of groups of red-complex (e.g., Porphyromonas gingivalis) and/or orange-complex (e.g., Fusobacterium nucleatum) periodontal pathogens were compared between cases and controls using conditional logistic regression models and MiRKAT.

RESULTS

Participants with higher taxonomic microbial alpha-diversity had a non-statistically significant decreased risk of HNC. No case-control differences were found for beta diversity by MiRKAT model (all p > 0.05). A greater relative abundance of red-complex periodontal pathogens (OR = 0.51, 95 % CI = 0.26-1.00), orange-complex (OR = 0.38, 95 % CI = 0.18-0.83), and both complexes' pathogens (OR = 0.32, 95 % CI = 0.14-0.75), were associated with reduced risk of HNC. The presence of oral fungi was also strongly associated with reduced risk of HNC compared with controls (OR = 0.39, 95 % CI = 0.17-0.92).

CONCLUSION

Greater taxonomic alpha-diversity, the presence of oral fungi, and the presence or relative abundance of multiple microbial species, including the red- and orange-complex periodontal pathogens, were associated with reduced risk of HNC. Future studies with larger sample sizes are needed to evaluate these associations.

Assessment of Social Vulnerability in Pediatric Head and Neck Cancer Care and Prognosis in the United States

IMPORTANCE

Prior investigations in social determinants of health (SDoH) in pediatric head and neck cancer (HNC) have only considered a narrow scope of HNCs, SDoH, and geography while lacking inquiry into the interrelational association of SDoH with disparities in clinical pediatric HNC.

OBJECTIVES

To evaluate the association of SDoH with disparities in HNC among children and adolescents and to assess which specific aspects of SDoH are most associated with disparities in dynamic and regional sociodemographic contexts.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study included data about patients (aged ≤19 years) with pediatric HNC who were diagnosed from 1975 to 2017 from the Surveillance, Epidemiology, and End Results Program (SEER) database. Data were analyzed from October 2021 to October 2022.

EXPOSURES

Overall social vulnerability and its subcomponent contributions from 15 SDoH variables, grouped into socioeconomic status (SES; poverty, unemployment, income level, and high school diploma status), minority and language status (ML; minoritized racial and ethnic group and proficiency with English), household composition (HH; household members aged ≥65 and ≤17 years, disability status, single-parent status), and housing and transportation (HT; multiunit structure, mobile homes, crowding, no vehicle, group quarters). These were ranked and scored across all US counties.

MAIN OUTCOMES AND MEASURES

Regression trends were performed in continuous measures of surveillance and survival period and in discrete measures of advanced staging and surgery receipt.

RESULTS

A total of 37 043 patients (20 729 [55.9%] aged 10-19 years; 18 603 [50.2%] male patients; 22 430 [60.6%] White patients) with 30 different HNCs in SEER had significant relative decreases in the surveillance period, ranging from 23.9% for malignant melanomas (mean [SD] duration, lowest vs highest vulnerability: 170 [128] months to 129 [88] months) to 41.9% for non-Hodgkin lymphomas (mean [SD] duration, lowest vs highest vulnerability: 216 [142] months vs 127 [94] months). SES followed by ML and HT vulnerabilities were associated with these overall trends per relative-difference magnitudes (eg, SES for ependymomas and choroid plexus tumors: mean [SD] duration, lowest vs highest vulnerability: 114 [113] months vs 86 [84] months; P < .001). Differences in mean survival time were observed with increasing social vulnerability, ranging from 11.3% for ependymomas and choroid plexus tumors (mean [SD] survival, lowest vs highest vulnerability: 46 [46] months to 41 [48] months; P = .43) to 61.4% for gliomas not otherwise specified (NOS) (mean [SD] survival, lowest vs highest vulnerability: 44 [84] months to 17 [28] months; P < .001), with ML vulnerability followed by SES, HH, and HT being significantly associated with decreased survival (eg, ML for gliomas NOS: mean [SD] survival, lowest vs highest vulnerability: 42 [84] months vs 19 [35] months; P < .001). Increased odds of advanced staging with non-Hodgkin lymphoma (OR, 1.21; 95% CI, 1.02-1.45) and retinoblastomas (OR, 1.31; 95% CI, 1.14-1.50) and decreased odds of surgery receipt for melanomas (OR, 0.79; 95% CI, 0.69-0.91) and rhabdomyosarcomas (OR, 0.90; 95% CI, 0.83-0.98) were associated with increasing overall social vulnerability.

CONCLUSIONS AND RELEVANCE

In this cohort study of patients with pediatric HNC, significant decreases in receipt of care and survival time were observed with increasing SDoH vulnerability.

Selected trends in head and neck cancer epidemiology in Slovakia - an international comparison

BACKGROUND

Head-and-neck malignant neoplasms (diagnosis group C00-C14, according to ICD-10) form a heterogeneous group of diseases with close anatomical localization. The incidence is twice to three times higher in men than in women and is increasing worldwide.

OBJECTIVE

The aim of our analysis was to estimate changes of incidence and mortality rates of head-and-neck malignancies associated with anatomical topographic regions over the time as well as to compare these indicators in different selected countries of the world. Secondary endpoints included the assessment of patients' age distribution, clinical stages of newly diagnosed cases, and point prevalence of the disease in the Slovak Republic (SR).

MATERIAL AND METHODS

The data base for the calculations was obtained from national databases and outputs of the National Cancer Registry (NCR) of the SR (with summary data available from the National Epidemiological Portal of Malignant Tumors, which analyzed data from 1984-2003 and was available until 2009, the remaining data were obtained from annual analyses of the NCR of the SR and the National Centre for Health Information (NCZI)), from the Statistical Office of the SR, and from the IARC WHO global database outputs on incidence, mortality, prevalence and survival of the patients. Incidence and mortality data in the SR were available up to 2012 (including) and up to 2021 (including), respectively. A log-linear joinpoint regression model was used to analyze the development of incidence and mortality rates over time by using Joinpoint Regression Program software. To achieve maximum precision in the estimated total surviving population of patients with head and neck malignant neoplasms, a model was developed to calculate the point (overall) prevalence based on absolute numbers of long-term registered national counts of newly diagnosed patients, mortality from the disease, overall mortality, and survival probability. The representation of clinical stages of head and neck carcinoma in the SR was compiled from available national data (2000-2012) and from predictions and does not consider changes in TNM classifications over the time.

RESULTS

The age-adjusted (to the world standard population, ASR-W) incidence rate and the age-adjusted (ASR-W) mortality rate of head-and-neck malignant tumors in the SR have shown a significantly decreasing tendency in men since 1990; however, in women both of these indicators have shown a significant increasing tendency, especially the significantly growing incidence since 2004. In 2012, the overall age-adjusted incidence and mortality rate of head-and-neck cancers in the SR were significantly higher in males (ASR-W incidence 22.6/100,000 and ASR-W mortality 15.26/100,000) compared to females (ASR-W incidence 4.21/100,000 and ASR-W mortality 1.52/100,000). More than 75% of newly diagnosed cases are already in advanced and metastatic clinical stages, which is the most unfavourable survival factor. The absolute prevalence of these patients in the SR was estimated to be N = 9,395 in the year 2021.

CONCLUSION

It is necessary to get a current and well evaluated epidemiological overviews to be able to plan preventive and intervention programs in oncology.
