Objective. To evaluate the performance of high-risk human papillomavirus (HPV) DNA testing in urine samples compared to that of cervical sample testing in Northern Thailand. Methods. Paired urine and cervical samples were collected during the follow-up of women with a previous positive HPV test. HPV testing was performed using the Cobas 4800 HPV Test. Linear Array assay was used for genotyping in selected cases. Results. Paired urine and cervical samples were obtained from 168 women. Of 123 paired samples with valid results, agreement in the detection of high-risk HPV DNA was present in 106 cases (86.2%), with a kappa statistic of 0.65 (substantial agreement). Using the cervical HPV results as a reference, the sensitivity of urine HPV testing was 68.6% (24/35) and the specificity 93.2% (82/88). For the detection of histologic high-grade squamous intraepithelial lesion or worse (HSIL+), the sensitivity of urine HPV testing was 80.0% (4/5) and the specificity 78.0% (92/118). Conclusion. Although urine HPV testing had a rather low sensitivity for HPV detection, its sensitivity for histologic HSIL+ detection was high. For clinical use of urine HPV testing, standardization of specimen collection and processing techniques or application of a more sensitive test, especially in the detection of HPV52 and HPV58, is necessary.

To examine the utility of human papillomavirus (HPV) DNA testing for the screening of cervical cancer and its precursors, a prospective cohort study was performed in which a total of 8156 women with a median age of 36 years were enrolled. Two smear samples scraped from the uterine cervix were served for Papanicolaou test and HPV DNA testing (Hybrid Capture-II system). HPV-positive samples were further examined for HPV subtype using a DNA microarry chip. Women with cytologic abnormality or those with high-risk HPV DNA were further examined by colposcopy to determine histologic diagnosis. High-risk HPV DNA was detected in 11% of the general population, with higher prevalence of specific types, including 52, 16, 58, 51, 56, and 18. As expected, younger women were likely to have increased frequency of HPV infection. Notably, HPV DNA testing detected all 45 cases of cervical intraepithelial neoplasia (CIN) 3, while cytologic findings were negative in 6 of these cases. It is of particular interest that CIN was commonly associated with multiple HPV types, while invasive cancers had a single type of HPV. In terms of both sensitivity and positive predictive value in detecting the CIN, HPV DNA testing is superior to cytology. However, most importantly, HPV DNA testing in combination with cytology significantly improved the efficacy to CIN screening.

Objective: Immunochemical detection of the protein p16INK4a in cervical cytology is used in combination with Ki-67. Cells positive for both proteins are certain to have been transformed by high-risk HPV. p16/Ki-67 immunocytochemistry provides a significant improvement in specificity over cytology and HPV DNA testing. However, p16/Ki-67 immunocytochemistry also has its limitations. Study Design: The research is based on the follow-up of 1,131 patients for whom p16/Ki-67 immunocytochemistry was performed with cytology. Dependencies on the age of patients with LSIL, number of p16/Ki-67-positive cells, and different results during repeated examinations were analyzed. Results: In LSIL, positive p16/Ki-67 is less specific for ≥CIN2/HSIL for patients younger than 30 years compared to patients aged 30 years or older (61.1 vs. 75.7%, p < 0.013). Using a score of 10 p16/Ki-67-marked cells as a positive result instead of 1 led to significantly higher specificity (89.0 vs. 70.2%, p < 0.001). This modified threshold offers better risk assessment in LSIL. In repeated immunocytochemical investigations, 28.4% of the results deviated from the first examination. Conclusion: The abovementioned discrepancies can be interpreted as hints about the molecular biological causes of suboptimal performance of p16/Ki-67. An efficient and reliable application of p16/Ki-67 immunocytochemistry requires knowledge of its methodological limitations.
