head and neck squamous cell carcinoma

Tuesday 30 March 2010

head and neck squamous cell cancer (HNSCC); squamous cell carcinoma of the head and neck

Definition: Squamous cell carcinoma originating from the oral cavity, lip, larynx and pharynx are grouped under head and neck squamous cell carcinomas (HNSCC).

HNSCC-specific genetic alterations detection using saliva

Noninvasive identification of HNSCC-specific genetic alterations using saliva would have immense potential in early diagnosis and screening, particularly among high-risk patients.

Noninvasive high-throughput multiplex ligation-dependent probe amplification identified discrete gene signatures that differentiated HNSCC patients from normal controls providing proof-of-concept for noninvasive HNSCC detection.

Etiology - Tumorigenesis


  • In Africa, oncogenic HPV infection was found in 19.23% of HNSCCs, with genotype 16 predominating. HPV-related HNSCC tended to occur at younger age compared to non-HPV-related HNSCC. (25236828)


- Fanconi anemia (FA) and dyskeratosis congenita (DC) are rare inherited syndromes that cause head and neck squamous cell cancer (HNSCC).

  • Inactivation of FANCB may play a role in the pathogenesis of sporadic HNSCC.
