OBJECTIVE: To develop a new platform for genotyping human papillomavirus (HPV) and to investigate its effect in clinical application. METHODS: A pair of common primers of 18 HPV subtypes for PCR, was designed in HPV conservative L1 region. Genotyping probes for detecting 15 high-risk HPV subtypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 and 68, together with 3 low-risk HPV 6, 11 and 42 were selected respectively from Genbank and fixed on membrane to make DNA chip. PCR amplification and DNA chip technology were optimized. 100 clinical samples were used to investigate the effect of HPV genotyping DNA chip. Veracity of the genotyping results was verified by sequencing. RESULTS: From the 100 clinical samples, 30 were found to be HPV positive, including high-risk HPV subtypes 16, 18, 33, 45, 51, 58, and 66, and low-risk HPV 6, 11 and 42. The sensitivity tested by standard samples was up to 10 copies of HPV DNA. CONCLUSION: The HPV genotyping system developed here with DNA chip showed high sensitivity and specificity, suitable to be applied in clinical practice for HPV diagnosis and investigation on the prevalence of HPV sub-types.
Young-age sexual activity, multiple sexual partners, number of pregnancies, smoking and human papilliomavirus (HPV) infections are factors commonly considered as promoters of cervical tumorogenesis. Cervical carcinoma patients' prognosis correlates significantly with staging (according to FIGO classification). In early stages lymph-node involvement is considered as the most important prognostic factor. Other factors are: initial volume of the lesion, lymphatic and blood vessels involvement, depth of cervical invasion. Also parametrium involvement seems to decrease the rate of 5-year survival. The aim of the research was to estimate correlation between HPV DNA lymph node presence and pathologic parameters of primary tumour in surgically treated cervical carcinoma patients. We analysed DNA isolated from lymph nodes sampled intra-operatively from 134 patients, surgically treated for cervical cancer with PCR. We confirmed the presence of HPV DNA sequences in lymph nodes in 81 (60.5%) cases. Lymph node presence of HPV DNA rate was significantly higher in: advanced tumours, cases with initial lesion volume exceeding 10 cm3, cases with uterus and vaginal involvement and with initial tumour invasion deeper than 10 mm.
