Abstract Context.—In contrast to previous studies about the association of oral squamous cell carcinoma with human papillomavirus (HPV) 16/18, the associations between nonmalignant oral lesions (chronic inflammation, submucous fibrosis, leukoplakia, and squamous papilloma) and HPV are much less well understood. Objective.—We conducted this study using an in situ polymerase chain reaction in situ hybridization assay, which is one of the most sensitive methods for in situ viral detection. Other known oral cancer risk factors, including betel quid chewing and cigarette smoking, were also analyzed. Design.—Oral specimens from 23 patients with submucous fibrosis, 36 patients with leukoplakia, 22 patients with squamous papilloma, and 21 patients without significant lesions were analyzed for the presence of HPV DNA. Their betel quid chewing and cigarette smoking histories were reviewed. Results.—HPV-16 and HPV-18 were frequently identified in all 3 oral lesions (61.5% and 42.1%), while HPV-6 and HPV-11 were seen only in squamous papilloma (21.1% and 5.0%). HPV-18, betel quid chewing, and smoking were significantly associated with leukoplakia and squamous papilloma, while only betel quid chewing and smoking were significantly associated with submucous fibrosis. Multivariate analysis showed that the betel quid chewing habit remained an independent factor for leukoplakia and squamous papilloma. Conclusions.—Our data indicated that betel quid chewing and smoking habits are 2 important risk factors for these nonmalignant or premalignant oral lesions, while for high-risk HPV, only HPV-18—not HPV-16—is a significant risk factor for leukoplakia and squamous papilloma.

Objetivo: determinar a frequência da persistência do HPV em mulheres tratadas para o adenocarcinoma cervical. Método: trata-se de um estudo quantitativo, descritivo, retrospectivo, do tipo coorte, com 77 mulheres genotipadas para o HPV antes do tratamento e com adenocarcinoma cervical. Coletou-se novo material de secreção cervical após o tratamento para a realização da detecção do DNA do HPV por reação de cadeia da polimerase. Utilizou-se o programa estatístico Epi Info 7.1.4. para a análise dos dados. Resultados: observou-se que, das 77 pacientes, foi possível determinar a genotipagem do HPV após o tratamento em 30 mulheres e, destas, 7 (23,3%) apresentaram o HPV detectável. Encontraram-se os tipos de HPV dos quais quatro pacientes (57,1%) estavam com o HPV 31, sendo que, em uma paciente, estava associado ao HPV 18; o 33 em duas mulheres (28,6%), sendo que em uma estava associado ao HPV 16 e uma apresentou os HPV 11 e 56 associados (14,2%). Conclusão: detectou-se o HPV na secreção cervical em 23,3% das mulheres após o tratamento para o adenocarcinoma de colo uterino, sendo o HPV 31 o tipo mais frequente.

Our aim was to determine the prevalence of human papillomavirus (HPV) types 16 and 18 in cervical adenocarcinoma (and its precursors) in Scottish patients. Nucleic acid was extracted from paraffin-embedded, formalin-fixed tissues. We examined 119 cases of invasive adenocarcinoma, 20 cases of adenocarcinoma in situ, and 16 cases of normal glandular epithelium. HPV DNA was detected by polymerase chain reaction using type-specific primers for the E6 and E7 genes of HPV-16 and HPV-18 with conformation of HPV genotype by subsequent restriction fragment length polymorphism. HPV DNA was identified in 87 (62.6%) cases, with HPV-16 being detectable in 65 (47%) cases and HPV-18 in 41 (29%) cases. All the cases of normal tissue tested negative for HPV-16 and/or HPV-18. No significant relation between infecting HPV type (16 or 18) and subtypes of disease (within the invasive category and between the preinvasive and the invasive categories) was noted. Our findings support that HPV-16, along with HPV-18, are likely to play a significant role in the pathogenesis of cervical adenocarcinomas and that cervical cancer screening strategies that incorporate oncogenic HPV testing, and prophylactic vaccines that target these types, will be beneficial for the reduction of adenocarcinoma and associated glandular precursors.

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.
