Background

Head and neck cancer (HNC) incidence is on the rise in the UK and globally, with up to a 16% increase in the past decade.1There is evidence to suggest that these cancers have relatively higher upstaging risk due to shorter volume doubling time.2 The COVID-19 pandemic has caused immeasurable tragedy to all and especially those with malignancies. Patients with non-resolving oral lesions were unable to access adequate primary care and those with previous HNC were not adequately followed-up in secondary care due to the global pandemic, which made its first appearance in January 2020 in the UK.3 Various preventative methods were introduced to triage patients and avoid delayed diagnoses and treatment to patients at risk of developing HNC.4

Methods

Our dedicated maxillofacial emergency database provided data related to patients attending the emergency department (ED). We retrospectively collected data from the period between March 2020 and October 2021, which coincided with the different peaks and phases of the COVID-19 pandemic in the UK. We included only proven malignant lesions, excluding patients who attended with, and formally diagnosed with, benign entities. The data were referenced with available histopathology records and electronic patient records to confirm diagnoses and outcomes.

Results

A total of 2,774 patients were recorded on the maxillofacial emergency database of our North London teaching hospital (Table 1). In total, 34 patients presented with oral ulceration and non-odontogenic neck swellings and nine patients were subsequently diagnosed to have HNC. More than two-thirds of the patients were men (67%) and their ages ranged between 41-89 years (average: 64.22 years; median 63.61 years). More than half of the cohort were white and the rest comprised of people of Asian, Romanian and Bulgarian descent. Eight patients presented with persistent or non-resolving oral 'swellings' and one patient presented with a painful neck swelling.

All patients underwent diagnostic biopsies between 0-17 days (average seven days) after first review in ED. None of the patients were delayed as per the recommended waiting targets for the suspicious head and neck cancer pathway. All patients were graded to have stage IV cancers and only one patient had ablative surgery which is standard treatment for oral cancers.5 One-third of patients (n = 3) had recurrent or progressive disease and two patients died due to the destructive disease.

Discussion

The UK NHS EDs noted a significant drop in patients during the lockdown period by about 50%.6 Of those patients attending ED, the majority were due to severe COVID-19-related symptoms. The lockdown also meant that many patients were asked to self-isolate and quarantine away from their families and consequently received reduced access to help and medical services. There was significant collateral damage to other patient groups, including patients with new malignancies or previous HNC. Referrals via the two-week wait pathway for suspicious HNCs reduced by 84% during the initial lockdown period.7

A total of 54 patients were diagnosed with HNC in our unit during the period between March 2020 and October 2021 and 17% (n = 9) of these patients attended via the ED. Although the cohort is small, the staging and extent of disease is alarming. It is therefore inferred that the lack of access to essential/urgent care services during the COVID-19 pandemic and consequent reduction in referrals via the two-week wait clinics were likely causes of this presentation in the emergency department. It is also understood that there was inherent fear among patients to venture out or seek help, even when problems or symptoms occurred.

Metzger et al. noted higher pathological tumour staging in newly diagnosed cancer patients during the COVID-19 pandemic.8 Similar findings were noted in patients presenting sinonasal malignancies during this period.9 Although our cohort is small, it represents the trends noted in other countries and institutions dealing with similar patients and entities.

Conclusion

We have presented our findings related to oral/oropharyngeal malignancies presenting as maxillofacial emergencies during these unprecedented times. Our aim is to promote safe, robust triaging and early assessment by providing all possible means of support to this vulnerable cohort, especially in this unpredictable climate.
