Lateral cystic neck masses in adults: a ten-year series and comparative analysis of diagnostic modalities

BACKGROUND

In adults, the solitary lateral cystic neck mass remains a diagnostic challenge with little solid material to target for cytology and few clues on imaging modalities to suggest underlying malignancy.

METHOD

This study was a retrospective review of patients presenting with a lateral cystic neck mass to a tertiary academic head and neck centre over a 10-year period.

RESULTS

A total of 25 of 157 cystic lesions were subsequently malignant on paraffin section histopathology, with the youngest patient being 42 years. In the age cohort over 40 years, 30 per cent of males and 10 per cent of females were diagnosed with malignancy. The ipsilateral palatine tonsil was the most common primary site (50 per cent). A total of 85 per cent of cases demonstrated integrated human papillomavirus infection. Age, male sex and alcohol were significant risk factors on univariate analysis. Ultrasound-guided fine needle aspiration cytology and magnetic resonance imaging represented the most accurate pre-open biopsy tests.

CONCLUSION

The authors of this study advocate for a risk-stratified, evidence-based workup in patients with solitary lateral cystic neck mass in order to optimise timely diagnosis.

The potential role of imaging techniques in avoiding neck dissection during salvage surgery after head and neck carcinoma treated with bioradiotherapy

OBJECTIVE

This study aimed to evaluate the effectiveness of computed tomography and positron emission tomography-computed tomography prior to salvage surgery after head and neck carcinoma treated with bioradiotherapy and to look at the role of neck dissection in this setting.

METHOD

This study was a retrospective chart review of a series of consecutive patients with locally advanced head and neck squamous cell carcinoma treated with bioradiotherapy. Radiological and pathological stages were compared to evaluate the accuracy of computed tomography and positron emission tomography-computed tomography in detecting occult neck metastasis in the context of recurrence of primary tumour. In order to assess the impact of neck dissection on survival, Kaplan-Meier survival curves after salvage surgery with and without neck dissection were derived.

RESULTS

A total of 268 patients were identified, of which 22 underwent salvage surgery. The negative predictive value of computed tomography and positron emission tomography-computed tomography was excellent. Neck dissection did not represent an improvement on overall, disease specific and regional recurrence free survival (p = 0.67, p = 0.91 and p = 0.62, respectively) amongst clinically and radiologically negative necks.

CONCLUSION

Conservative treatment of the neck should be considered when dealing with patients with primary site recurrence or persistent disease after bioradiotherapy without evidence of neck disease.

North East London coronavirus disease 2019 protocol for diagnostics in two-week wait head and neck cancer patients

Background

The coronavirus disease 2019 pandemic requires urgent modification to existing head and neck cancer diagnosis and management practices. A protocol was established that utilises risk stratification, early investigation prior to clinical review and a reduction in aerosol generating procedures to lessen the risk of coronavirus disease 2019 spread.

Methods

Two-week wait referrals were stratified into low, intermediate and high risk. Low risk patients were referred back to primary care with advice; intermediate and high risk patients underwent investigation. Clinical encounters and aerosol generating procedures were minimised. A combined diagnostic and therapeutic surgical approach was undertaken where possible.

Results

Forty-one patients were used to assess feasibility. Thirty-one per cent were low risk, 35 per cent were intermediate and 33 per cent were high risk. Thirty-three per cent were discharged with no imaging.

Conclusion

Implementing this protocol reduces the future burden on tertiary services, by empowering primary care physicians to re-refer low risk patients. The protocol is applicable across the UK and avoids diagnostic delay.

Head and neck squamous cell cancer associated with lymphoproliferative malignancies is aggressive

BACKGROUND

Patients with non-Hodgkin's lymphoma and chronic lymphocytic leukaemia are at an elevated risk of further malignancy. Head and neck squamous cell carcinoma often presents with cervical lymph node metastasis, and can pose a diagnostic challenge in patients with non-Hodgkin's lymphoma or chronic lymphocytic leukaemia who may have pre-existing palpable neck nodes.

METHODS

A retrospective case review of a health board was conducted to identify patients with head and neck squamous cell carcinoma with a previous diagnosis of non-Hodgkin's lymphoma or chronic lymphocytic leukaemia.

RESULTS

Four patients with head and neck squamous cell carcinoma that developed after non-Hodgkin's lymphoma or chronic lymphocytic leukaemia were identified. Two patients had a background of non-Hodgkin's lymphoma treated with chemotherapy. The remaining two patients had a background of chronic lymphocytic leukaemia under active surveillance. Three out of the four patients died within 30 months of diagnosis.

CONCLUSION

Head and neck squamous cell carcinoma following non-Hodgkin's lymphoma or chronic lymphocytic leukaemia is aggressive. A heightened clinical suspicion is essential to facilitate early diagnosis and treatment of head and neck squamous cell carcinoma in patients with dual pathology.

The 100 most cited manuscripts in head and neck cancer: a bibliometric analysis

OBJECTIVE

This study aimed to highlight the key studies that have led to the current understanding and treatment of head and neck cancer.

METHOD

The Thomson Reuters Web of Science database was used to identify relevant manuscripts. The results were ranked according to the number of citations. The 100 most cited papers were analysed.

RESULTS

A total of 63 538 eligible papers were returned. The median number of citations was 626. The most cited paper compared radiotherapy with and without cetuximab (3205 citations). The New England Journal of Medicine had the most citations (23 514), and the USA had the greatest number of publications (n = 66). The most common topics of publication were the treatment (n = 45) and basic science (n = 19) of head and neck cancer, followed by the role of human papillomavirus (n = 16).

CONCLUSION

This analysis highlighted key articles that influenced head and neck cancer research and treatment. It serves as a guide as to what makes a 'citable' paper in this field.
