Changes in human papillomavirus genotypes associated with cervical intraepithelial neoplasia grade 2 lesions in a cohort of young women (2013-2016).

Predicting regression of cervical intraepithelial neoplasia grade 2 in women under 25 years

Predicting regression of cervical intraepithelial neoplasia grade 2 in women under 25 years.

Objective s: To identify the variants of genotype HPV that most often found in ICC at Dr Soetomo Hospital Surabaya. Materials and Met h ods : This was an explorative study with cross sectional approach. Specimens used were 30 formalin fix parrafin embedded from squamous cell carcinoma (SCC), adenocarcinoma (AD) dan adenosquamous carcinoma (AS) cervival cancer parients at Dr Soetomo Hospital Surabaya around Januari-Desember 2013, then used for DNA virus extraction and continued for PCR and HPV genotyping. Result : The result of HPV genotyping showed 10 positives from SCC, 6 positives and 4 negatives from AD, and 9 positives and 1 negative from AS. HPV infections in SCC were single infection by HPV 16, 18, 45, 56, and multiple infection by HPV 16+45, in AD were single infection by HPV 16,18, anad multiple infection by HPVhr+hr 68b+72 and HPVlr+hr  6+18+45, and in AS were single infection by HPVhr 16, 18, 45 and mutiple infection by HPV lr+hr 6+59. Conclusion : Infections HPV in ICC were single infection by HPV16, 18, 45, 56 and mutiple infection by HPV16+45, 68b+72, 6+18+45, 6+59. HPV 18 has highest prevalence in ICC patient from Dr Soetomo Hospital, followed by HPV16, 6, 45, 56, 59.

Human papillomavirus (HPV) is the necessary cause of cervical cancer. Published data on the epidemiology of HPV in women with invasive cervical cancer (ICC) in New Zealand (NZ) are limited. This cross-sectional study investigated the distribution of high-risk and low-risk HPV types in cervical specimens collected from women throughout NZ who had been diagnosed with ICC between 2004 and 2010. Women aged ≥18 years, with ICC International Federation of Gynecology and Obstetrics stage Ib or greater were identified from the five tertiary public hospitals in NZ regularly treating women with ICC. Women were enrolled in the study only after obtaining informed consent. Stored, formalin fixed, paraffin-embedded cervical specimens were retrieved and histopathologically reviewed to confirm the diagnosis of ICC. Cervical specimens were tested for HPV using polymerase chain reaction-short fragment10; HPV DNA was detected using DNA enzyme immunoassay and typed by reverse hybridization line probe assay. 242 women were enrolled and ICC was histologically confirmed in 227 samples. HPV infection was detected in 88.5% (n = 201; 95% CI: 83.7–92.4) of women with ICC; high-risk HPV types were detected in 87.2% of women. The most commonly detected HPV types were HPV-16 (51.1%) and HPV-18 (20.7%), followed by HPV-31 (4.0%), HPV-45 and HPV-52 (3.1% each). Overall, HPV distribution was highest (94.3%) in women aged 30–39 years at diagnosis and a higher distribution of HPV-16 (68.8%) was observed in women younger than 30 years. The overall distribution of HPV types between Maori and non-Maori women were similar. HPV-positive women with ICC stage II or greater were less likely to be infected with HPV-16/18 (P = 0.002) or HPV-18 (P = 0.029) compared with the other high-risk types. Single type infection and multiple infections were detected in 93.5% and 5.5% of women, respectively. HPV-16, HPV-18, HPV-31, HPV-45 and HPV-52 were the most commonly detected high-risk HPV types. Findings from the study fill an important data gap on HPV type distribution from NZ which will help facilitate better understanding of the epidemiology of HPV in NZ women. NCT01328028
