HPV detection in cervical cancer patients in northern Poland

Comparison of HPV Testing and Colposcopy in Detecting Cervical Dysplasia in Patients With Cytological Abnormalities

“…In our study, the incidence of HPV 31 (18.2%), HPV 33 (11.1%) and 30 (11.1%) was surprisingly high compared with the incidence of the other genotypes. Our results were consistent with those from previous studies in Poland, in which HPV 16 was found to be the most common genotype and HPV 18 was less common (12)(13)(14). A similar HPV distribution has been reported in other European countries, including Italy, Greece, Denmark, Estonia and Latvia (31,(35)(36)(37)(38).…”

“…The prevalence of HPV genotypes depends on the geographic region and demographic factors (3,(8)(9)(10)(11). In the Polish population, HPV genotypes 16 and 18 are the most prevalent and are observed in more than 72.4% of women with cervical cancer (12)(13)(14). The incidence rate and mortality from cervical cancer vary depending on the existing screening program with regard to cytology, colposcopy or HPV testing.…”

Prevalence of human papillomavirus genotypes in cervical cancer in Maiduguri, Nigeria

“…Higher prevalence rates of HPV were reported in studies carried out in Croatia (92-7%) [11], USA (91.3%) [16], India (93.0%) [17], Thailand (94.8%) [18], Malawi (97.0%) [19], South Africa (92.1%) [20] and Ibadan Nigeria (90.7%) [21]. However, relatively low HPV prevalence rates were also observed in Poland (53.0%) [22], Khuzestan Iran (43.3%) [23] and Tehran Iran (49.0%) [24]. These differences in the reported prevalence rates of HPV in cervical cancer tissues could be attributed to several factors among which include geographical variations [10, 12, 13], quality and quantity of biological specimens [25-28], methods of DNA extraction and sensitivity [29], and specificity of HPV detection methods [27, 28, 30-32].…”

“…Se empleó el programa de 11,16,18, 31 y 33 mediante la acción de la enzima de restricción AFA1. Los casos positivos en los que no se pudo determinar el genotipo fueron catalogados como VPH-X (13) .…”

“…El VPH se clasifica en más de 189 genotipos según la secuencia de su ADN y 40 de estos son capaces de infectar el cuello uterino. Se subdividen en genotipos de bajo riesgo (BR) (VPH - 6,11,13,40,42,43,44,54,59, 61, 70, 72, 81) y alto riesgo (AR) (VPH - 16,18,31,33,35,39,45,51,52, 56 y 58) según su probabilidad de producir CCU. Un reciente estudio con 8977 especímenes de CCU VPH positivo encontró que los genotipos de AR son responsables de alrededor del 90% de los casos, y los genotipos 16/18 son responsables del 70% de los casos en el mundo (4) .…”
