Impact of the COVID-19 pandemic on stage and incidence of head and neck cancer: A rapid review and meta-analysis.

OBJECTIVES: This rapid review aims to evaluate the impact of the COVID-19 pandemic on incidence of head and neck cancer (HNC) and stage distribution at diagnosis. DESIGN: Rapid review and meta-analysis. PARTICIPANTS: Comparative data for new HNC patients between a pre-pandemic cohort (before March 2020) and a pandemic cohort (after March 2020 during the lockdown period). MAIN OUTCOMES MEASURED: Data on tumour stage, incidence, referral pathway (number of new patient referrals), or workload levels (number of HNC treatments). Data on stage were summarised as odds ratios (OR) with 95% confidence intervals (CI), and data related to changes in numbers of diagnoses, referrals, and workload levels were summarised as a narrative synthesis. RESULTS: A total of 31 reports were included in this review. Individually 16 out of 23 studies did not show a significant impact on stage relative to the pre-pandemic period. However, the meta-analysis revealed that patients diagnosed with HNC during the pandemic were 16% more likely to have nodal involvement (OR = 1.16; 95% CI 1.00-1.35), 17% more likely to have a late overall stage (OR = 1.17; 95% CI 1.01-1.36), and 32% more likely to present with advanced tumour extent (T3 and T4 stage) (OR = 1.32; 95% CI 1.08-1.62). Data on incidence was extremely limited and not currently sufficient to assess trends in burden of disease. CONCLUSIONS: This review indicates that during the COVID-19 pandemic, there was upstaging of HNC at diagnosis, suggesting the provision of care to HNC patients was significantly affected.

The COVID-19 pandemic has not changed stage at presentation nor treatment patterns of head and neck cancer: A retrospective cohort study.

OBJECTIVES: To evaluate the impact of the COVID-19 lockdown measures on HNC, by comparing the stage at presentation and treatment of HNC before and after the most severe COVID-19 restrictions. DESIGN: A retrospective cohort study. SETTING: A regional cancer network serving a patient population of 2.4 million. PARTICIPANTS: Newly diagnosed patients with HNC between June and October 2019 (pre-pandemic) and June and October 2021 (post-pandemic). MAIN OUTCOME MEASURES: Symptom duration before diagnosis, stage at diagnosis, patient performance status (PS) and intent of treatment delivered (palliative vs. curative). RESULTS: Five hundred forty-five patients were evaluated-250 in the 2019 and 295 in the 2021 cohort. There were no significant differences in symptom duration between the cohorts (p = .359) or patient PS (p = .821). There were no increased odds of presenting with a late (Stage III or IV) AJCC cancer stage in 2021 compared with 2019 (odds ratio [OR] = 0.90; 95% confidence interval [CI]: 0.76-1.08); nor increased odds of receiving palliative rather than curative treatment in 2021 compared with 2019 (OR = 0.68; 95% CI: 0.45-1.03). CONCLUSION: The predicted stage shift to more advanced disease at the time of diagnosis of HNC due to the COVID-19 pandemic has not been realised in the longer term. In keeping with this, there was no difference in symptom duration, patient PS, or treatment patterns between the 2019 and 2021 cohorts.

Head and neck cancer incidence is rising but the sociodemographic profile is unchanging: a population epidemiological study (2001-2020).

Background: Increasing incidence of head and neck cancers (HNCs), driven by rising rates of oropharynx cancer (OPC), has been recorded around the world. This study examined trends in HNC and subsites (oral cavity, oropharynx, and larynx cancers) in Scotland focusing on assessing whether the sociodemographic profile has changed over the past 20 years. Methods: Scottish Cancer Registry data (2001-2020) including European Age Standardised Rates of HNC and subsites were analysed in multivariate Poisson regression by age, sex, area-based socioeconomic status, and year of diagnosis (with interaction tests). Results: Overall HNC and oral cavity cancer (OCC) incidence remained relatively stable. OPC incidence rates increased by 78%, while larynx cancer incidence declined by 27%. Over time, there were marginal shifts to a slightly older age profile for HNC (p = 0.001) and OCC (p = 0.001), but no changes in OPC (p = 0.86) and larynx cancer (p = 0.29). No shift in the sex profile of HNC was observed except for minor increases in female OCC rates (p = 0.001), and the socioeconomic distribution remained unchanged across all HNC subsites. Conclusions: There have been no significant changes in the sociodemographic profile of HNC in Scotland over the last 20 years, despite the changing trends in HNCs with dramatically increasing incidence rates in OPC and reducing larynx cancer. This information can be used to target or stratify HNC prevention and control.
