“AimThe aim of this study was to evaluate the clinical performance of the Amplicor HPV test, which detects 13 high-risk human papillomaviruses (HR-HPV), and to determine the association between consistent HR-HPV infection and progression of cervical intraepithelial neoplasia (CIN) 2 to CIN3.

Material and MethodsThis multi-institutional prospective study enrolled 122 women diagnosed with CIN2 by central pathological review. Subjects were tested at study entry and every 6 months over a 24-month period by cytology, Amplicor HPV test and colposcopy. Central pathological review was performed

at the end of the study or if CIN progression was suspected.

ResultsNinety-three of the 122 participants completed all tests in the study and were included in the analysis. HR-HPV

was detected in 87/93 (93.5%) participants at study entry. Twenty-four of the 87 HR-HPV-positive participants progressed to CIN3, compared with none of the six participants who were HR-HPV-negative at study entry. The positive predictive value, negative predictive value, sensitivity and specificity of the Amplicor HPV test at study entry for predicting CIN3 progression were 27.6%, 100%, GSK1210151A 100% and 8.7%, respectively. Sixty-two participants were HR-HPV-positive from study entry through to study completion, 24 of whom progressed to CIN3. None of 31 participants without continuous HR-HPV detection progressed to CIN3. For continuous HR-HPV detection, the positive predictive value, negative predictive value, sensitivity and specificity of the Amplicor HPV test were 38.7%, 100%, 100% and 44.9%, respectively.

ConclusionsAll participants who progressed to CIN3 were continuously HR-HPV-positive. The Amplicor HPV test thus demonstrated a good performance for predicting CIN3 progression.”
“In recent years there has been Selleck AZD2014 a dramatic increase in the prevalence of skin cancer worldwide. There has been a huge amount of research literature on skin

cancer especially in the last 10-15 years. There is no doubt that this is in direct relation to the increases in prevalence of the disease on a worldwide basis. Australian and American research has led in the field and again it is probable that this has been due to the increase in rates of skin cancer in those countries. This paper provides a comprehensive review of the existing international literature in the area. (c) 2008 Elsevier Ltd. All rights reserved.”
