Table 2 Concordance between histological type of OPSCC and ancillary testing for high-risk HPV

From: Low prevalence of p16-positive HPV-related head-neck cancers in Thailand: tertiary referral center experience

Tumor type n p16+ ISH+ qPCR+a
Keratinizing 84 14 4 5/9
Non-keratinizing with maturation 18 10 4 5/8
Non-keratinizing 8 7 8 5/5
Total 110 31 16 15/22
  1. a only p16-positive cases with adequate DNA yield were tested by qPCR
  2. ISH DNA in situ hybridization, qPCR quantitative polymerase chain reaction
