| Abstract: | Objective: Multiple human papillomavirus (HPV) infection of the uterine cervix has been suggested as a risk factor for persistent HPV infection, resulting in the development of invasive cervical cancer. The aim of this study was to reveal the actual state of multiple HPV infection in Japanese patients with invasive cervical cancer. Methods: Freshly-frozen 60 invasive cervical cancer tissues were examined for genotyping of HPV. The presence of HPV genotypes in the cancer tissues was determined by an HPV-DNA array, which can discriminate 25 different HPV genotypes with high sensitivity and specificity. Results: Among 60 samples, 59 (96.7%) were positive for HPV. The three common genotypes were HPV-16 (83.3%), HPV-18 (45.0%) and HPV-52 (28.3%). Multiple HPV infection was observed in 47 of 60 samples (78.3%), in which 42 cases were infected with more than one high-risk genotypes (70.0%). The multiple high-risk HPV infection was significantly more prevalent in patients below 40 years old (14/15, 93.3%) than in patients 40 years and over (28/45, 62.2%). Conclusion: The HPV-DNA array is the preferable method to detect HPV genotypes. Multiple HPV infection in Japanese patients with invasive cervical cancer seemed to be more frequent than reported in the literature. |
