Pain preceding recurrent head and neck cancer

Area of Science:

• Oncology
• Pain Medicine
• Head and Neck Surgery

Background:

• Recurrence of primary head and neck cancers poses a significant clinical challenge.
• Identifying early indicators of cancer recurrence is critical for timely intervention and improved patient prognosis.
• Orofacial pain is a common symptom, but its association with cancer recurrence requires further investigation.

Purpose of the Study:

• To investigate the relationship between severe orofacial pain and the recurrence of primary head and neck cancers.
• To determine the temporal association and clinical characteristics of orofacial pain preceding cancer recurrence.
• To assess the diagnostic utility of standard imaging techniques in detecting early recurrence when accompanied by orofacial pain.

Main Methods:

• Retrospective analysis of 12 patients diagnosed with primary head and neck cancer recurrence over a 7-year period.
• Detailed review of patient records focusing on the onset, progression, and characteristics of orofacial pain.
• Evaluation of diagnostic methods employed, including clinical examination, plain radiography, magnetic resonance imaging (MRI), and computed tomography (CT).

Main Results:

• Twelve patients experienced head and neck cancer recurrence preceded by severe orofacial pain.
• In 10 of 12 patients, pain began within 6 months post-treatment; it was progressive in 11 of 12.
• Despite severe pain, standard diagnostic evaluations (clinical, radiographic, MRI, CT) often failed to reveal malignancy, with pain frequently misattributed to denture irritation.

Conclusions:

• Severe orofacial pain can be an early, albeit often overlooked, symptom of head and neck cancer recurrence.
• The absence of clear pathological findings on standard imaging should not preclude consideration of malignancy in patients with persistent orofacial pain.
• Further research is warranted to develop more sensitive diagnostic markers for cancer recurrence presenting with orofacial pain.
