Pap Cytology and Human Papillomavirus (HPV) Genotypes in Western Romania: A Retrospective Analysis.

Background and objective Vigorous proactive measures are needed to combat cervical cancer, linked to the human papillomavirus (HPV). HPV genotyping aids in identifying high-risk strains, enabling targeted screening and risk assessment. This informs treatment decisions, reducing cervical cancer cases. In light of this, we conducted a retrospective analysis of Pap cytology and HPV genotypes to assess western Romania's new screening program. Understanding HPV prevalence, genotype correlations, and risk factors will help refine risk stratification models and enhance public health strategies. Methodology This retrospective study analyzed Pap smears from 195 patients with a mean age of 40 years [standard deviation (SD): 12 years], with a peak of incidence between 25 and 30 years. The patient cohort, with equal representation from urban and rural areas, comprised sexually active women of reproductive age presenting to the Gynaecology Ambulatory of the Municipal Emergency Clinical Hospital Timișoara over two years. Patients not sexually active and those in menopause were excluded. HPV genotyping was done on 67 patients. Data were analyzed using JASP, employing descriptive statistics, frequency tables, contingency tables, chi-squared test, odds ratio, and Fisher's exact test. Results Among 195 patients undergoing Pap smear tests, the most prevalent finding was negative (77.95%), indicating no abnormal cells detected. A smaller proportion of patients exhibited low-grade squamous intraepithelial lesions (LSIL, 11.28%) or atypical squamous cells of undetermined significance (ASC-US, 8.72%) findings. High-grade lesions (HSIL, ASC-H) were rare. For cytology grading, Category II (CII) was the most prevalent (75.90%), followed by Category III (CIII, 24.10%). HPV genotyping was performed on a subset of patients (n=67). Among them, Type 16 was the most frequent (28.36%), followed by Other high-risk types (20.89%), Type 16 (28.35%), and Type 18 (13.43%). HPV testing was not performed for 65.64% of the patients. Overall, the study suggests that a significant majority of the patients had normal Pap smears. However, a small proportion did have abnormal findings, including HPV infection. These findings highlight the importance of Pap smear screening for early detection of cervical abnormalities. Conclusions Our study from western Romania highlights the importance of HPV testing and Pap cytology in cervical cancer prevention. HPV testing is a potent tool for identifying high-risk women, and when combined with Pap cytology, it provides a more comprehensive screening strategy. Our research also revealed a diverse HPV genotype distribution, suggesting the need for broader-spectrum vaccines like the nonavalent vaccine. Despite our study's limitations, our findings underscore the need for including HPV testing in national screening guidelines. Future research should focus on larger studies and the cost-effectiveness of broader-spectrum vaccines. Implementing policies based on these findings could lead to more effective cervical cancer prevention in western Romania.
