Background
Human papillomavirus (HPV) is a major risk factor for cervical cancer.
Methods
We evaluated the clinical significance of the HPV DNA chip genotyping assay (MyHPV chip, Mygene Co.) compared with the Hybrid Capture 2 (HC2) chemiluminescent nucleic acid hybridization kit (Digene Corp.) in 867 patients.
Results
The concordance rate between the MyHPV chip and HC2 was 79.4% (kappa coefficient, κ = 0.55). The sensitivity and specificity of both HPV tests were very similar (approximately 85% and 50%, respectively). The addition of HPV result (either MyHPV chip or HC2) to cytology improved the sensitivity (95%, each) but reduced the specificity (approximately 30%, each) compared with the HPV test or cytology alone. Based on the MyHPV chip results, the odds ratio (OR) for ≥ high-grade squamous intraepithelial lesions (HSILs) was 9.9 in the HPV-16/18 (+) group and 3.7 in the non-16/18 high-risk (HR)-HPV (+) group. Based on the HC2 results, the OR for ≥ HSILs was 5.9 in the HR-HPV (+) group. When considering only patients with cytological diagnoses of “negative for intraepithelial lesion or malignancy” and “atypical squamous cell or atypical glandular cell,” based on the MyHPV chip results, the ORs for ≥ HSILs were 6.8 and 11.7, respectively, in the HPV-16/18 (+) group.
Conclusions
The sensitivity and specificity of the MyHPV chip test are similar to the HC2. Detecting HPV-16/18 with an HPV DNA chip test, which is commonly used in many Asian countries, is useful in assessing the risk of high-grade cervical lesions.

Abstract PDF

BACKGROUND
Human papillomavirus (HPV) infection can be detected by in situ hybridization (ISH), in which a punctate signal pattern indicates integrated HPV DNA and a diffuse pattern denotes the presence of episomal viral DNA. This study was conducted to evaluate the usefulness of an HPV ISH assay for invasive cervical cancer.
METHODS
The HPV ISH assay for high-risk HPV and immunohistochemical staining for p16(INK4a), p53, bcl-2, and Ki-67 were performed in a tissue microarray of 279 cervical cancers.
RESULTS
High-risk HPV ISH was positive in 194 (69.5%) of the samples. Punctate, diffuse, and mixed signal patterns were observed in 157 (56.3%), one (0.4%), and 36 cases (12.9%), respectively. Positive results in high-risk HPV ISH were associated with p16 and bcl-2 expression (p = 0.01 and p < 0.01, respectively). According to a Cox regression analysis, HPV infection and its surrogate immunohistochemical markers such as p16, bcl-2, and Ki-67 were not independent prognostic factors, but stage and grade were independent prognostic factors.
CONCLUSIONS
Our results confirm that an HPV ISH assay is reasonably sensitive for HPV infection and that it might be useful to identify integrated HPV DNA in formalin-fixed and paraffin-embedded specimens. Further study encompassing HPV type, E2/E6 ratio, and therapeutic modality is necessary to understand the clinical meaning of HPV status in cervical cancer.

Abstract PDF

This study was performed to compare the efficacy between a DNA chip method and a Hybrid-Capture II assay (HC-II) for detecting human papillomavirus in patients with intraepithelial lesions of the uterine cervix. From May, 2005, to June, 2006, 192 patients with abnormal colposcopic findings received cervical cytology, HC-II and HPV DNA chip tests, and colposcopic biopsy or conization. We compared the results of HC-II and HPV DNA chip in conjunction with liquid based cervical cytology (LBCC) and confirmed the results of biopsy or conization. The sensitivity of the HPV DNA chip test was higher than HC-II or LBCC. The HPV DNA chip in conjunction with LBCC showed higher sensitivity than any single method and higher sensitivity than HC-II with LBCC. We confirmed that the HPV DNA chip test was more sensitive for detecting HPV in cervical lesions than HC-II, and that it would provide more useful clinical information about HPV type and its multiple infections.

Abstract PDF: This study was performed to compare Surepath(TM) liquid-based smear and a conventional cervicovaginal smear with reference to a histological diagnosis. A hybrid capture test (HCII) was also performed and analyzed. We collected matched cases for cervicovaginal cytology- histology: 207 cases for conventional cytology (CC) and 199 cases for liquid-based cytology (LBC). HCII was performed in 254 patients. When a cytological diagnosis of ASCUS or above (ASCUS+) is classified as positive and a histological diagnosis of LSIL+ is classified as positive, the sensitivity and specificity for LBC was 91.7% and 75.9%, respectively and the sensitivity and specificity for CC was 62.6% and 96.1%, respectively. When a cytological and histological diagnosis of LSIL+ is classified as positive, the sensitivity and specificity for LBC was 77.5 and 96.6%, respectively and the sensitivity and specificity for CC was 49.7% and 100%, respectively. When a histological diagnosis of LSIL+ is classified as positive, the sensitivity and specificity for HCII was 78.9% and 78.1%, respectively. The concordance ratio between the cytological and histological diagnosis was 80.4% (kappa=76.0) for LBC and 56.5% (kappa=55.1) for CC. LBC is more sensitive and less specific then CC, as a cytological cutoff level of ASCUS, but more sensitive and equally specific, as a cytological cutoff level LSIL or HSIL. LBC is more reliable with a high concordance ratio between the cytological and histological diagnosis.

Abstract PDF: Restrictive dermopathy (RD) is a rare and lethal autosomal recessive skin disorder that presents with rigid and tense skin, multiple joint contractures and fixed facial expression. We report herein two siblings from consecutive pregnancies affected with RD. Both siblings died of respiratory insufficiency at a day after birth. An autopsy for the first baby and a skin necropsy for the second baby were performed. The gross findings of both were characterized by thin, translucent skin with prominent vessels, multiple joint contractures resulting in hyperflexed position, and a typical facial appearance with a fixed open mouth in the O-position. Such manifestations are typical features of RD. At the autopsy of the first baby, no internal organ abnormality was found. The histologic findings of the skin of the second baby revealed a thin dermis consisting of a flat dermal-epidermal junction, hypoplastic skin appendages and compactly arranged collagen bundles. Elastic tissue stain showed markedly decreased elastic fibers.
