Use of a high-risk human papillomavirus DNA test as the primary test in a cervical cancer screening programme: a population-based cohort study.

OBJECTIVE: To present the results of the first 2 years of a human papillomavirus (HPV) test-based screening programme outside the research context. DESIGN: Population-based cohort study. SETTING: A cervical service screening programme in Italy. POPULATION: Women aged 25-64 years invited to screening from April 2009 to April 2011. METHODS: Eligible women were invited to undergo an HPV test: those with a negative HPV test went on to the next screening episode; those with a positive HPV went on to triage with a Pap smear. Women with positive cytology (i.e. positive for atypical squamous cells of undetermined significance or worse, ASC-US+) were referred to colposcopy, whereas those with negative cytology were referred to repeat HPV testing 1 year later. MAIN OUTCOME MEASURES: Participation rate, positivity at HPV and at triage, referral rate to colposcopy, positive predictive value for cervical intraepithelial neoplasia grade 2+ (CIN2+) at colposcopy, and detection rate for CIN2+. RESULTS: Participation increased compared with the previous Pap programme (60.6 versus 43.9%). The HPV positivity rate was 7.0; 39.6% of Pap smears were scored as positive, and therefore 2.8% of the women screened were referred for immediate colposcopy. The compliance of women who scored positive for HPV and negative for Pap for repeat HPV testing at 12 months was 78.6%, and the HPV positivity rate was 56.6%. The overall referral rate to colposcopy was 4.6%. The overall detection rate for CIN2+ was 4.5 versus 1.5% of the Pap programme (25-34 years, 8.2%; 35+ years, 3.6%). CONCLUSIONS: Compared with the traditional Pap test, the HPV programme recorded a higher response to invitation and an increased DR for CIN2+. The most critical aspects were the reading of cytology in women that were positive for HPV and the increased workload at colposcopy.

Extensive anal condylomatosis: prognosis in relation to viral and host factors.

OBJECTIVE: To evaluate the clinical course of extensive anal condylomatosis in relation to treatment modalities, patient comorbidity and immune function, and associated papillomavirus (HPV) sequences. METHOD: Clinical data, treatment modalities and follow-up were recorded and analysed in relation to host and viral type. Histology, immunohistochemistry and molecular analyses for HPV search and typing were performed on formalin-fixed paraffin-embedded samples. RESULTS: Sixteen patients [14 males, median age 41.8 years (range 19-66)] affected by extensive anal condylomatosis [10 Buschke-Lowenstein Tumors (BLT) and 6 condylomatosis] treated in three different Italian institutions were included. There was associated preoperative anal intraepithelial neoplasia grade 3 (AIN3) in one and invasive carcinoma in three patients. After radical resection (n = 16) recurrence occurred in 4/10 (40%) BLT patients. Malignancy before or after treatment developed in 5/16 (31.25%) patients. HPV sequences were present in all the samples of 15 evaluable patients (types 6 or 11, 9 patients; type 16, 6 patients). A statistically significant association was found between presence of HPV type 16 and both malignancy and recurrence. Viral variant L83V was present in 3/4 HPV 16 positive recurrent cases. CONCLUSION: Radical resection resulted in a favourable clinical course. Typing of HPV sequences in the management of patients affected by extensive anal condylomatosis may be useful.
