Granulosa cell tumor - Different faces of one neoplasm. A case series.

Introduction: Granulosa cell tumor (GCT) accounts for 3-5 % of all ovarian malignancies, being the most common among those originating from the sex cords and ovarian stroma. GCTs can be divided into juvenile and adult types, with the latter occurring mostly in perimenopausal women. These hormonally active tumors present diverse clinical manifestations, primarily related to elevated estrogen levels.

Baseline data on distribution of human papillomavirus (HPV) genotypes in cervical samples of gynecological patients before implementation of population-based HPV vaccination program in Poland.

Objectives: Free-of-charge vaccination against human papillomavirus (HPV) of 12-13-year-old teenagers was introduced on the 1st of June 2023 in Poland. Data on baseline HPV genotype cervical distribution are crucial to evaluate potential changes after full implementation of the vaccination program. We aimed at evaluating the status of HPV infection and distribution of HPV genotypes in cervical cytology of gynecological patients tested in one of the largest HPV laboratories in Poland.

Effect of Ureaplasma/Mycoplasma genital tract infection on preterm labor.

Objectives: Genitourinary tract infections in pregnant women are one of the causes of abnormal pregnancy development including miscarriages, premature labor or premature rupture of membranes (PPROM). Atypical bacteria responsible for reproductive tract infections include Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum and Ureaplasma parvum. Identification of pathogens and appropriately selected therapy can improve obstetric outcomes in patients with symptoms of threatened miscarriage or threatened preterm labor.

Knowledge of HPV and HPV Vaccination among Polish Students from Medical and Non-Medical Universities.

Human papillomavirus (HPV) is a common sexually transmitted infection that can cause both benign and malignant lesions. HPV vaccines, preferably administered before the onset of sexual activity, have demonstrated remarkable efficacy in preventing HPV-related cancers. The impact of a healthcare provider's recommendation on HPV vaccine acceptance is substantial.

Effect of HPV Vaccination on Virus Disappearance in Cervical Samples of a Cohort of HPV-Positive Polish Patients.

The introduction of human papillomavirus vaccines revolutionized cervical cancer prevention. Our research hypothesis is that HPV vaccination affects the remission of HPV in cervical swabs. We provide a prospective, ongoing, 24-month, non-randomized study in HPV-positive women.

Clinical use of the Onclarity test with extended HPV genotyping and phenotyping in patients with suspected squamous intraepithelial lesions.

Objectives: Human papillomavirus (HPV) is the most widespread virus with oncogenic potential that infects humans and there is a need to look for the most effective screening method among the population. Understanding the role of HPV in cervical dysplasia and viruses typing increased the usage of HPV-based cervical cancer screening tests using genotyping.

Material And Methods: We aim to assess the usefulness the Onclarity Test with extended genotyping and phenotyping of HPV in detecting cervical squamous intraepithelial lesions in 695 subjects who registered for regular cervical screening or due to abnormal LBC result or positive HPV results.

Epithelial Ovarian Cancer-Varied Treatment Results.

Ovarian cancer (OC) is the eighth most common cancer worldwide and is usually diagnosed in advanced stages. Despite many available data, no treatment results have been reviewed in Poland. This study enrolled 289 first-time patients treated between 2018 and 2021 by the Department of Oncology of the Poznań University of Medical Sciences (SKPP).

Uterine sarcoma - time is worth its weight in gold.

Leiomyosarcoma is one of the most common types of soft tissue sarcoma in adults, and it can occur in almost any part of the body. Uterine leiomyosarcoma constitutes 1% of all gynaecological tumours. Most diagnosed sarcomas are not even suspected before surgery.

Prevalence of HPV and Assessing Type-Specific HPV Testing in Cervical High-Grade Squamous Intraepithelial Lesions in Poland.

The prevalence and distribution of oncogenic human papillomavirus (HPV) genotypes in women who underwent screening for cervical cancer in the Wielkopolska region, Poland, were assessed, and the correlation of genotypes with the histological results was evaluated. Cervical samples were collected from 2969 women for cervical cancer screening. Participants were screened by liquid-based cytology and HPV genotyping ( = 1654) and referred to colposcopy and punch biopsy ( = 616) if recommended.

Expression of E4 Protein and HPV Major Capsid Protein (L1) as A Novel Combination in Squamous Intraepithelial Lesions.

We aim to describe the relationship between the immunohistochemical expression patterns of HPV E4 markers and the presence of HPV major capsid protein (L1) in cervical tissues obtained by biopsy of patients with abnormal liquid-based cytology (LBC) results, HR HPV infections, or clinically suspicious cervix. A novel HPV-encoded marker, SILgrade-E4 (XR-E4-1), and an HPV (clone K1H8) antibody were used to demonstrate the expression in terminally differentiated epithelial cells with a productive HPV infection in the material. A semiquantitative analysis was performed based on light microscope images.

Histopathological discrepancies between colposcopy-directed biopsy and LEEP-conization observed during SARS-CoV-2 pandemic.

Objectives: Long-term exposure to the human papillomavirus (HPV) is a known cause of squamous intraepithelial lesions that lead to cervical cancer. The loop electrosurgical excision procedure (LEEP) conization is an established treatment method. According to the latest recommendations, we present a paper to evaluate the effectiveness of various diagnostic methods of squamous intraepithelial lesions.

Immunity after HPV Vaccination in Patients after Sexual Initiation.

Vaccinations against human papillomavirus (HPV) are included in the primary prevention of precancerous intraepithelial lesions and HPV-related cancers. Despite the undeniable effectiveness of vaccination in the juvenile population, there is still little research on the effect in patients after sexual initiation. Our study aims to assess anti-HPV (L1 HPV) antibodies in healthy patients and diagnosed cervical pathology after 9-valent vaccination.

Human papillomavirus genotyping in high-grade squamous intraepithelial lesion.

Objectives: Human papillomavirus infection is one of the most common sexually transmitted infections. Long-term exposure to the HPV leads to high-grade squamous intraepithelial lesions affecting cervical cancer. Knowledge about the distribution of HPV genotypes is crucial to guide the introduction of prophylactic vaccines.

Human papillomavirus genotyping in low-grade squamous intraepithelial lesions.

Objectives: Human papillomavirus infection is one of the most common sexually transmitted infections. Histological LSIL in 70-80% of cases will regress spontaneously, while a subset is associated with residual risk for a future precancerous lesion. This study evaluates the performance of HPV genotypes for LSIL preceded by normal or mildly abnormal Pap smear.

Remission of HPV infection after LEEP-conization - a retrospective study.

Objectives: Human papillomavirus (HPV) infection is one of the most common sexually transmitted diseases. Long-term exposure to the HPV is a known cause of squamous intraepithelial lesions that consequently lead to cervical cancer development. The loop electrosurgical excision procedure (LEEP) conization is an established early cervical cancer treatment method.

Genotyping of human papillomavirus DNA in Wielkopolska region.

Objectives: Human papillomavirus infection is one of the most common sexually transmitted diseases. Long-term exposure to the HPV leads to development of high-grade squamous intraepithelial lesions that can eventually transform into cervical cancer. The aim of the study was to assess the HPV genotype distribution in patients with abnormal pap smear and provide prospective study.
