The detection of human papillomavirus type-16 and -6b was performed in 28 cases of hypopharyngeal squamous cell carcinomas by polymerase chain reaction. Human papillomavirus (HPV) DNAs extracted from paraffin-embedded metastatic lymph node tissue were used for polymerase chain reaction with amplification of the E1 region of HPV genotype 6b and the E6 region of HPV genotype 16. HPV type 6b sequences were detected in three cases; positive amplification of type 16 sequences was also seen in three cases. These findings suggest that HPV infection might be closely associated with the development of some hypopharyngeal carcinomas as it is with laryngeal and uterine cervical carcinogenesis.

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

D027383	Papillomaviridae	A family of small, non-enveloped DNA viruses infecting birds and most mammals, especially humans. They are grouped into multiple genera, but the viruses are highly host-species specific and tissue-restricted. They are commonly divided into hundreds of papillomavirus "types", each with specific gene function and gene control regions, despite sequence homology. Human papillomaviruses are found in the genera ALPHAPAPILLOMAVIRUS; BETAPAPILLOMAVIRUS; GAMMAPAPILLOMAVIRUS; and MUPAPILLOMAVIRUS.
