Updated guidelines recommend HR\u2010HPV\u2013specific polymerase chain reaction (PCR) analysis over p16 immunohistochemistry on FNA specimens because p16 performs poorly on cytology material. PCR\u2010based assays on liquid cytology material have demonstrated excellent analytic performance; however, the diagnostic utility of a positive HR\u2010HPV PCR result in specimens with indeterminate cytomorphology remains uncharacterized.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The authors retrospectively identified 279 head and neck FNA specimens that had paired HR\u2010HPV PCR testing on residual liquid cytology material over a 5\u2010year period. The positive predictive value for histopathologically confirmed squamous cell carcinoma on surgical follow\u2010up was calculated within each cytologic interpretive category.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The HR\u2010HPV PCR results were positive in 50.2% of specimens, negative in 40.9%, and indeterminate in 9.0%. The HR\u2010HPV positivity rate ranged from 0% in specimens categorized as negative for malignancy to 57.3% in cytologically positive specimens, with 19.0%, 41.2%, and 50.0% positivity in the atypical, suspicious, and nondiagnostic categories, respectively.

Blinded slide review additionally identified 15 cytologically positive specimens in which the definitive malignant interpretation depended substantially on HR\u2010HPV positivity; all 15 were confirmed as squamous cell carcinoma.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A positive HR\u2010HPV PCR result on liquid cytology material carries a positive predictive value of 100% for malignancy in cytologically indeterminate head\u00a0and neck FNA specimens. These findings support integrating HR\u2010HPV PCR analysis into routine cytologic interpretation with the potential to upgrade some indeterminate specimens to malignant when HR\u2010HPV is detected, expediting definitive treatment and sparing patients additional, invasive sampling.<\/jats:p>\n
