Polymorphism of clinical manifestation of HPV infection in the genital mucosa - 3-year retrospective study.

Background: Human papillomaviruses (HPVs) are associated with a wide variety of cutaneous and mucosal infections and with malignancies in humans. More than 100 HPV types have been identified, some of which have affinity for skin and others for mucosal sites.

Aim: The purpose of this study came from our desire to support the "Stop Cervical Cancer" campaign, adopted as "Cervical Cancer Removed as a Public Health Problem", following the World Health Organization (WHO) initiative in 2019-2020. At European level, cervical cancer mortality has fallen by more than 30% over the past 30 years, through coherent, consistent and comprehensive prevention programs based on accurate and consistent public information. Romania is in an unfavorable situation with regard to incidence (32.8 new cases∕100 000 women) and cervical cancer mortality (10.9 deaths∕100 000 women). Free Babeş-Papanicolau (Pap) testing for early detection of cervical cancer was valid this year until March.

Patients, Materials And Methods: The study runs over a period of three years, between 2016-2018, in the "Elena Doamna" Hospital of Obstetrics and Gynecology, Iaşi, Romania. Of the 8500 patients hospitalized for various diseases (ovarian cysts, uterine fibroids, endometriosis, abnormal vaginal bleeding, dysmenorrhea, ectopic pregnancies, placenta praevia, spontaneous abortions and on demand, benign, malignant tumors), only 382 were present in the ambulatory for Pap test. For the other conditions, Pap test denied because the patients did not want this but to solve the condition for which they presented themselves.

Results: We retrospectively review 382 Pap tests of patients who presented themselves in the Ambulatory Service of the Hospital both at the advice of the gynecologist and due to the program initiated by the WHO and supported by the Department of Public Health, Iaşi: "Cervical cancer can be eliminated as a problem of public health". Lesions equal to or worse than high-grade squamous intraepithelial lesion (HSIL) equivalate with high-grade lesions including HSIL (cervical intraepithelial neoplasia - CIN1, CIN2). Endometrial lesions were excluded from the study. As seen of this campaign, the number of patients has increased in 2018 (242 cases), compared to 46 cases in 2017 and 94 cases in 2016.

Conclusions: Our study demonstrated that 35% (7/20) of HSIL-confirmed biopsies previously had negative HPV assays. Despite the previous negative HPV tests, a wide variety of HPV genotypes has been detected in most biopsies. In our case, we frequently identified the HPV 59 and 45 strains, 51 cases with HSIL lesions presented a first positive HPV test, 13 cases with low-grade squamous intraepithelial lesion (LSIL) showed three negative HPV tests. Prevention plays an important role in reducing the incidence of cervical cancer cases. The Pap test is now considered the primary prevention method, but consecutive vaccination significantly increases protection against high-risk HPV strains. Education plays an important role in the prophylaxis of HPV infection and cancer. It should be instituted in schools, from puberty age through partnerships or government programs with public health directorates and university hospitals or using European funds.
