Abstract
Prostate cancer (PC) incidence and mortality are steadily increasing. Causation of PC is not clearly understood; in particular, role of human papillomaviruses (HPV) is still disputable. The review contains analysis of literature data on possible participation of HPV powerful biological carcinogens, in PC genesis. PC incidence increase in persons with immunodeficiency indicates involvement of some infectious agent in the disease etiology. Several research groups communicated HPV DNA finding including that of oncogenic types in PC specimens (transrectal biopsies). There are limited data on the occurrence of oncogenic HPV 16 oncoprotein E7 in such specimens and on its unfavorable effect on disease prognosis. The successful attempt is known to transfect normal human prostate cells with oncogenic HPVDNA in vitro. Epidemiological data on associations of PC with HPV are controversial. It may result from the considered in the present review certain technical peculiarities of these studies. Controlfor serum antibodies to HPV E6 and E7 oncoproteins recognized to indicate HPV-positive tumor growth in an organism has not been performed yet in PC patients. DNA of oncogenic HPV is rather commonly found in organs adjacent to prostate--urethra, rectum, urinary bladder. In the study held in Russia on a group of healthy men examined for sexually transmitted diseases genitourinary HPVinfection was found in every second person; 42% of them harbored oncogenic HPV. Possible participation of oncogenic HPV in PC genesis deserves close attention and further study.

Summary
Заболеваемость раком предстательной железы (РПЖ) и смертность от него неуклонно возрастают. Рак предстательной железы (РПЖ) занимает второе место в мировой структуре онкологической заболеваемости мужчин и шестое — в структуре смертности мужчин от онкопатологии. В большинстве стран, где проводят регистрацию заболеваемости РПЖ и смертности от этой формы рака, данные показатели в последние годы возрастают [1]. Заболеваемость РПЖ в разных странах варьирует в широких пределах, что обусловлено как генетическими факторами, так и различиями в образе жизни населения и принципах диагностики и лечения заболевания. There are limited data on the occurrence of oncogenic HPV 16 oncoprotein E7 in such specimens and on its unfavorable effect on disease prognosis. The successful attempt is known to transfect normal human prostate cells with oncogenic HPV DNA in vitro. Стандартизованный показатель смертности от РПЖ за этот период вырос на 35,2%, что особенно значимо на фоне общего снижения стандартизованного показателя смертности мужчин от всех злокачественных новообразований за тот же период (-10,5%) [5]
