It is widely accepted that HPV infection precedes the occurrence of neoplastic disease in a varying time frame, and HPV testing can detect 30-100% more cervical precancers than conventional cytology and 20-50% more precancers than liquid-based cytology. Low-grade squamous intraepithelial lesions include the categories of mild dysplasia, respectively cervical intraepithelial neoplasia grade 1, and complementary, various descriptors indicating the presence of Human papilloma virus, such as koilocytotic atypia or condilomatous dysplasia. High-grade squamous intraepithelial lesions cytologically consist of moderate and severe dysplasia, respectively cervical intraepithelial neoplasia grade 2, 3 and carcinoma in situ. The purpose of our paper is to analyze the cytological and colposcopic characteristics in low-grade squamous intraepithelial lesions and high-grade squamous intraepithelial lesions cervical lesions and to accomplish histological and immunohistochemical correlations in these cervical intraepithelial lesions. Systematic three-step colposcopic evaluation using successively, normal saline with or without green filter, acetic acid and Lugol staining provides enhanced efficiency to the colposcopic examination and allows a more individualized and targeted surgical, medical or expectant management. Special microscopic techniques are very important in diagnosing and grading cervical intraepithelial neoplasia.

This study aimed to describe Human Papilloma Virus (HPV) genotypes and women with cervical intraepithelial neoplasia (CIN) sociodemographic characteristics at the oncology reference centers. A secondary data of 325 records on women with CIN were analyzed from a cohort study database conducted in two public institutions in the oncological service in the Northeast of Brazil, from July 2014 to February 2016. The HPV genotype analysis was carried out on 142 through viral DNA sequence after amplifying PCR technique and compared the sequences identified in the GenBank databases. The women were predominantly 25 to 39 years old. The 325 biopsies revealed 17.6% low-grade of cervical intraepithelial lesion (CIN1) and 82.4% high-grade of cervical intraepithelial lesion (CIN2 or CIN3). Among the 142 HPV genotypes the most prevalent was HPV-16 (51.7%), followed by HPV-35 (6.9%) and HPV-45 (6.2%). HPV-18 was in only 2.1%. There was an association between HPV-16 and high-grade lesions (CIN2 or CIN3) (p=0.008). Although HPV-16 was the predominant genotype in cervical intraepithelial lesions, especially high-grade lesions (CIN2 or CIN3), HPV-35 was the second most frequent in high-grade lesions in this population. This suggests that other HPVs may be as prevalent as those commonly known in some regions.

Recently, there has been a steady growth of cervical cancer all over the world, especially in Russia. Patients with cervical cancer have become much younger. At the same time, the human papillomavirus is not only the main factor in the neoplastic process, but it is also one of the most common sexually transmitted infections in the world. The aim of the paper is to assess the prevalence and characteristics of human papillomavirus genotypes in patients with cervical intraepithelial neoplasia. Materials and Methods. During the periodic screening we examined 213 women of a reproductive age with HPV infection. All patients underwent liquid-based cytology and human papillomavirus genotyping by polymerase chain reaction. Results. We revealed that the prevalence of cervical intraepithelial neoplasia among women with papillomavirus infection was 80.3 % (n=171). According to human papillomavirus genotyping, HPV 16 (38 %) and HPV 33 (32 %) prevailed. We also observed positive high correlation between high-grade squamous intraepithelial lesions (HSIL) and HPV 18 (r=+0.759, p=0.001), a negative mean correlation between HPV 45 and low-grade squamous intraepithelial lesions (LSIL) (r=-0.643, p=0.002). A cohort of patients with severe intraepithelial cervical lesions demonstrated high viral load rates. Conclusion. According to the results obtained, we established the dominance of HPV 16 and HPV 33 genotypes in cervical intraepithelial neoplasia. There were significant differences between HSIL and LSIL patients with HPV 18 and HPV 45. There was also a correlation between an increase in the viral load with the severity of the pathological process. Keywords: human papillomavirus, intraepithelial cervical neoplasms, cervical cancer. В последние годы в мире, особенно в России, наблюдается неуклонный рост и «омолаживание» рака шейки матки. При этом вирус папилломы человека является не только основным фактором прогрессирования неопластического процесса, но и одной из наиболее распространенных инфекций, предаваемых половым путем, в мире. Цель. Оценить распространенность и характеристику генотипов папилломавирусной инфекции у пациенток с цервикальными интраэпителиальными неоплазиями. Материалы и методы. Проведено обследование 213 пациенток репродуктивного возраста с ВПЧ-инфекцией, пришедших на профилактический осмотр. Всем женщинам было выполнено цитологическое исследование жидкостным методом и генотипирование вируса папилломы человека методом полимеразной цепной реакции. Результаты. Распространенность цервикальных интраэпителиальных неоплазий среди женщин с папилломавирусной инфекцией составила 80,3 % (171 пациентка). Согласно данным генотипирования вируса папилломы человека превалировал 16-й (38 %) и 33-й типы (32 %). Выявлена положительная высокая корреляционная связь между цервикальными неоплазиями высокой степени онкогенного риска (HSIL) и 18-м типом ВПЧ-инфекции (r=+0,759 при р=0,001), отрицательная средняя корреляционная связь 45-го типа ВПЧ с низкой степенью онкогенного риска (LSIL) (r=-0,643 при р=0,002). Продемонстрированы высокие показатели вирусной нагрузки в когорте пациенток с тяжелыми внутриэпителиальными цервикальными поражениями. Выводы. По результатам полученных данных установлено доминирование 16-го и 33-го генотипов ВПЧ при цервикальных интраэпителиальных неоплазиях с наличием значимых различий между пациентами с HSIL и LSIL в отношении 18-го и 45-го типов, а также связь роста уровня вирусной нагрузки с увеличением степени тяжести патологического процесса. Ключевые слова: вирус папилломы человека, интраэпителиальные новообразования шейки матки, рак шейки матки.
