Head & neck cancers: What you’ll see, how to proceed

What is the diagnostic strategy? Oral cancers present with a lesion, often ulcerative, that should be examined by palpation with a gloved finger to describe the presence, color, and number of lesions; any tenderness; tissue consistency (soft, firm, hard); and fixation to underlying structures.¹⁵ The oropharynx should be examined without protrusion of the tongue, which obscures the oropharynx and can make it harder to depress the posterior part of the tongue.

A finding of leukoplakia (white plaques) and erythroplakia (red plaques) of the oropharynx might reflect benign hyperkeratosis or premalignant lesions; the plaques do not wipe off on examination. Referral to a dentist or otorhinolaryngologist for biopsy is indicated for all erythroplakia and leukoplakia, and for ulcers that persist longer than 2 weeks.¹⁶

(Note: Evidence is insufficient to support screening asymptomatic patients for oral and oropharyngeal cancers by physical examination. There is no US Food and Drug Administration-approved screening test for oral HPV infection.¹⁷)

How is it treated? A diagnosis of moderate dysplasia or carcinoma in situ should be treated with surgical excision to clear margins followed by routine monitoring every 3 to 6 months, for life.¹⁸ Topical medication, electrocautery, laser ablation, and cryosurgery are management options for less severe dysplasia.

Sinonasal cancer

What you need to know. Worldwide, sinonasal cancer accounts for approximately 0.7% of all new cancers but demonstrates strong genetic and regional associations, particularly among the Cantonese population of southern China.¹⁹ One-half of new sinonasal malignancies are SCC; the rest are adenocarcinoma, lymphoepithelial carcinoma, and rare subtypes.²⁰
