| Popis: | Objective: To determine the rates and types of human papilloma virus (HPV) infection in cervical cancer specimens from Saudi patients. Methods: One hundred specimens were randomly selected and retrieved from the achieved samples stored in the pathology department accessioned under the diagnosis of cervical cancer and carcinoma in situ between the years 1997 and 2007. Human papilloma virus in the clinical samples was detected using polymerase chain reaction amplification methods. Two primer systems are commonly used: the MY09-MY11 primers and the GP5+-GP6+ that amplify a wide range of HPV genotypes. Human papilloma virus isolates were genotyped using DNA sequencing and reverse line blot hybridization assay to identify the high-risk HPV genotypes. Results: Ninety cases fulfilled the diagnostic criteria and were analyzed. The rate of HPV genotype detection among cervical cancer samples was 95.5%. The most common HPV genotype detected by both methods was HPV-16 (63.4%), followed by HPV-18 (11.1%), HPV-45 (4.5%), HPV-33 (3.3%), and HPV-31, HPV-52, HPV-53, HPV-58, HPV-59, and HPV-66 with 2.2% prevalence rate each. Conclusions: Prevalence of HPV genotypes among patients with cervical cancer in Saudi Arabia is comparable to the international rates. The use of the reverse line blot hybridization assay genotyping method could be useful for classifying oncogenic HPV-positive women. It is relatively inexpensive and reliable and can be performed in routine practice or epidemiological study compared with the available standard commercial kits. |
