Cervical Biopsy, Smear Evaluation and Comparison of Human Papilloma Virus Subtypes Result

Objective: The aim of this study was to investigate the relationship between human papilloma virus (HPV) types which was worked with polymerase chain reaction (PCR) and immunohistochemistry methods and cvtology and biyopsy results. Materials and Methods: A total of 100 cases from hospital between 2010-2013 participitated in this study. Linear Array HPV genotyping test was worked with PCR, tissue biopsies was evaluated with light microscopy, HPV was detected with immunohistochemistry (IHK) method and results were compared evaluating of conventional smear preparations according to Bethesda. Results: While 61 cases included high risk (61%), 39 cases included low risk HPV (39%). HPV types with high risk such as HPV16, HPV6, HPV11, HPV18, HPV31 respectively detected in 24, 19, 9, 7, 2 cases. HPV types with low risk such as HPV66 detected in 7 cases. HPV16 was observed epithelial cell abnormality such as 9 ASCUS, 3 LSIL,1 ASC-H, 1 AGUS in 14/24 ratio (58%) and ILMAN was observed 10/24 ratio (42%). Between cytological diagnosis results and HPV types are significant relationship according to chi-square test (p=0.001). When the results of the biopsy tissue analyzed, 38 patients were diagnosed intraepithelial neoplasia and malignant, 62 cases were diagnosed inflammation and other benign featured. The relationship between tissue diagnosis and HPV types is significant according to chi-square test (p<0.001). HPV in tissue was positive in 44 cases. The relationship between HPV types and tissue HPV results are significant (p<0.001). The cytological tissue diagnosis of 19 patients with ASCUS has been reported as follows; 10 CIN1, 3 CIN2, 2 CIN3 and 4 inflammation. Negative and positive HPV results studied in tissue are not significant results with cytological diagnosis (p=0.02) and tissue diagnosis results (p=0.02). Conclusion: The important of HPV detection is obvious, but tissue changes as well as HPV detection are important. Thus combined use of testing, even in evaluation with the biopsy results may give more realistic results for all types of cancers worldwide.
