The prevalence of HPV infection among oropharyngeal squamous cell carcinomas patients in India is comparatively lower to that of the same worldwide.</p><p><bold> Aim.</bold> To find out the prevalence of HPV infection among oropharyngeal squamous cell carcinomas patients who presented in our hospital.</p><p><bold>Settings and design</bold>. Retrospective cross-sectional study.</p><p><bold>Materials and methods</bold>. Tissue block of 60 patients with biopsy-proven oropharyngeal squamous cell carcinomas were subjected to immunohistochemistry for evaluating p16 expression. The p16 expression pattern was correlated with the demographic details. Data was entered in Microsoft Excel and Statistical Analysis was done with the help of SPSS version 22 (IBM Corp. Released, 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp.).</p><p><bold>Results</bold>. Prevalence of HPV infection in our study was found to be 11.7 %. 85.8 % of all p16-positive patients had moderate-well differentiated disease. 6 out of 7 p16-positive patients had higher T stage (T3–4). All the patients who were p16+ were found to have a higher Nodal stage (N2–3). 100 % of all p16+ patients were found to have stage IV disease.</p><p><bold>Conclusion. </bold>Prevalence of HPV infection was found to be similar to that of previous studies conducted in India. These patients also presented with advanced nodal disease at presentation and thereby, an advanced overall stage.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Орофарингеальная плоскоклеточная карцинома часто связана с заражением вирусом папилломы человека (ВпЧ). Распространенность инфекции ВпЧ среди пациентов с данной патологией в Индии сравнительно ниже, чем в других странах.</p><p><bold>Цель исследования </bold>– определить распространенность инфекции ВпЧ среди пациентов с орофарингеальной плоскоклеточной карциномой, получавших лечение в нашей больнице.</p><p><bold>Дизайн исследования. </bold>Ретроспективное одномоментное исследование.</p><p><bold>Материалы и методы</bold>. Образцы тканей 60 пациентов с подтвержденным биопсией диагнозом «орофарингеальная плоскоклеточная карцинома» были исследованы иммуногистохимически на экспрессию p16. Было проведено сравнение профиля экспрессии p16 с демографическими данными. полученные результаты оценены с помощью программы Microsoft Excel. Статистический анализ выполнен с использованием программного обеспечения SPSS version 22 (IBM Corp. Released, 2013. IBM SPSS Statistics для Windows, версия 22.0, Армонк, Нью-Йорк: IBM Corp.).</p><p><bold>Результаты.</bold> Частота встречаемости ВпЧ в нашем исследовании составила 11,7 %. Среднеи высокодифференцированное заболевание наблюдалось у 85,8 % пациентов с положительной экспрессией p16. Шесть из 7 больных с такой экспрессией p16 имели более высокую T-стадию (T3–4), а все больные с таким показателем – высокую N-стадию (N2–3). У всех пациентов с положительной экспрессией p16 наблюдалось заболевание стадии IV.</p><p><bold>Заключение. </bold>Распространенность инфекции ВпЧ была близкой к значениям, полученным в других исследованиях в Индии. Для пациентов с этой инфекцией также были характерны вовлеченность лимфатических узлов (N-стадия) в патологический процесс и более высокая общая стадия заболевания.</p></trans-abstract><kwd-group xml:lang="en"><kwd>human papillomavirus infection</kwd><kwd>oropharyngeal cancers</kwd><kwd>prevalence of infection</kwd><kwd>Indian subpopulation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>инфицирование вирусом папилломы человека</kwd><kwd>орофарингеальный рак</kwd><kwd>распространенность инфекции</kwd><kwd>индийская субпопуляция</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sung H., Ferlay J., Siegel R.L. et al.
