RESUMO
Objective Cervical cancer (CC) is one of the leading causes of deaths from cancer among women worldwide. Viral infections is now one of the known risk factors for CC. The aim of this study was to investigate the presence of herpes simplex virus type 2 (HSV-2), human papilloma virus types 16 (HPV-16) and human papilloma virus types 18 (HPV-18) in Iranian patients with CC using the polymerase chain reaction (PCR). Materials and methods This case-control study was conducted on a total of 45 patients with CC from Khatam-Al-Anbiya Hospital, Hamadan, Iran during 2014, and 30 samples from healthy subjects as controls. The presence of HSV-2 and HPV-16/18 DNA sequences was detected by PCR. Results Eight of CC patients (17.77%) had HPV-16/18 DNA and only one patient (2.22%) with HSV-2 was identified. These viruses were not detected in control cases. Among HPV-16/18 positive patients, 62.5% and 37.5% biopsies were positive for HPV-16 and HPV-18, respectively. On the other hand, only one case (2.22%) was positive for HPV-16/18, but HSV-2 and this co-infection was not detected in the control group. Conclusion Our results demonstrate that there was no direct molecular evidence to support a cofactor relationship between HSV-2 and HPV-16/18 in cervical malignancies. However, the results about HPV-16/18 was in accordance with previous studies.
