Background
Human papillomavirus (HPV) infection can be detected by using several molecular methods, including Hybrid-Capture II (HC2) assay and variable HPV DNA chip tests, although each method has different sensitivities and specificities. Methods: We performed HPV 9G DNA Chip (9G) and PANArray HPV Genotyping Chip (PANArray) tests on 118 cervicovaginal swabs and compared the results with HC2, cytology, histology, and direct sequencing results. Results: The overall and high-risk HPV (HR-HPV) positivity rates were 62.7% and 44.9% using 9G, and 61.0% and 30.5% using PANArray, respectively. The positivity rates for HR-HPV with these two chips were significantly lower than 55.1% when HC2 was used. The sensitivity of overall HPV positivity in detecting histologically confirmed low-grade cervical squamous intraepithelial lesions or higher was 88.7% for all three tests. The specificity was 58.5% for 9G and 61.5% for PANArray, which was significantly lower than the 72.3% for HC2. With the HR-HPV⁺ genotype threshold, the sensitivity decreased to 75.5% for 9G and 52.8% for PANArray, which was significantly lower than the 88.7% for HC2. Comparison of the two chips showed concordant results in 55.1% of the samples, compatible results in 16.9%, and discordant results in 28.0%, exhibiting poor agreement in detecting certain HPV genotypes. Compared with direct sequencing, 9G yielded no discordant results, whereas PANArray yielded 31 discordant results (26.7%). Conclusions: Compared with HC2, the HPV genotyping tests showed lower sensitivity in histologic correlation. When the two chips were compared, the 9G was more sensitive and accurate for detecting HR-HPV than the PANArray.

Abstract PDF

Multifocal papillary thyroid carcinoma (mPTC) comprises about 20-30% of PTC. In mPTC, individual tumor foci can be identical or frequently composed of different histological types including follicular, solid, tall-cell or conventional patterns. We report a case of mPTC consisting of one encapsulated follicular variant of papillary thyroid carcinoma (FVPTC) and three conventional PTCs in a 44-year-old woman. This case genetically demonstrates unique features including the simultaneous presence of the BRAF V600E (T1799A) mutation and the BRAF K601E (A1801G) mutation in conventional PTC and FVPTC, respectively.

Abstract PDF

BACKGROUND
Recently, liquid-based cytology (LBC) has been introduced as an alternative to the conventional smear (CS) technique in thyroid fine needle aspiration, due to its diagnostic convenience.
METHODS
We assessed 77 cases of thyroid fine needle aspiration using the SurePath(TM) method (SP) as LBC and CS via split-sample techniques. BRAF mutation tests were carried out via polymerase chain reaction and pyrosequencing immediately after diagnosis or a delay of more than one year.
RESULTS
In a comparison between SP and CS, the rate of concordance between SP and CS was as high as 84.4% (kappa value, 0.754). In comparison with histologic diagnosis, the overall sensitivity was 100% for both. The specificity was 62.5% for SP and 56.3% for CS. Relative to CS, papillary carcinomas on SP slides revealed more accentuated nuclear irregularities, nucleoli, and reduced nuclear size. In contrast to CS, the delayed BRAFV600E mutation test using SP slides after 1-2 years failed. The use of new primers amplifying shorter product size could help the delayed test achieve success.
CONCLUSIONS
Differences in the diagnostic efficacy of SP and CS were negligible. The failure of the delayed BRAF mutation test on the SP slides might be associated with DNA degradation.
