INTRODUCTION: cervical cancer is a health concern worldwide. The South Kivu Province in the Eastern DR Congo is facing many cases of this disease but poorly screened and reported. The objective of this was to determine the prevalence of cell abnormalities at cervical cytology in a tertiary teaching hospital in Bukavu and their association with common risk factors of cervical cancer. METHODS: a cross-sectional study was conducted on 142 women attending the Provincial Referral Hospital of Bukavu (HPGRB) from February to December 2021...

The main risk factor involved in CIN2+ recurrence after treatment is the HPV persistent infection. The dysregulation of the immune system permits only HR-HPVs to become persistent infections, to promote cancer development and to increase the risk of recurrence after treatment. Therefore, there is a shift to a Th2-type cytokine pattern during the carcinogenesis pathway; for this reason, the neutrophil-lymphocytes ratio (NLR) could be a marker of this immunological change. The study aims to analyse the predictive role of NLR in the recurrence of High-grade CIN (CIN2+) after excisional treatment in a real-world life setting of patients treated for CIN2+ Design: cross-sectional study Participants/Materials, Setting, Methods: We examined a retrospective database of 444 patients, who attended the Colposcopy Service of our Department from 2011 to 2020 due to an abnormal screening pap smear and we compared the clinical characteristics to NLR performed at the time of diagnosis...

Cervical cancer (CC) is the fourth most common cause of cancer-related deaths amongst women worldwide. CC represents a major global healthcare issue, and Romania ranks the worst in mortality rates amongst EU countries. However, the early detection of CC can be lifesaving. To understand the testing process undergone by women in Romania, we performed a retrospective study, and investigated a cohort of 83 785 cervical cases from Romanian women aged 15-70, obtained in private-based opportunistic screening...

A next-generation sequencing (NGS)-based Ezplex HPV NGS kit (SML Genetree, Seoul, Korea) was used for human papillomavirus (HPV) screening. Of 885 cervical swab samples, HPV was detected in 162 samples. High-risk HPVs were detected in 82 samples, and other types of HPV were detected in 13 samples (HPV86, 71, 102, 91, and 114). At the read depth ≥ 500, NGS results exhibited 100 % agreement among repeated tests. HPV NGS results were compared with those of real-time PCR assays, Anyplex HPV28 (Seegene, Seoul, Korea) (n = 383) and Cobas HPV (Roche, Mannheim, Germany) (n = 64); concordances were 92...

OBJECTIVES: This study compares the follow-up rates of non-normal cervical screening samples between Denmark and Flanders (Belgium) to illuminate whether organizational differences between the health systems might affect the follow-up rates, e.g. sending of reminders in Denmark since 2012 compared to Flanders with no such system in place. METHODS: The study population included 48,082 Danish women and 22,271 Flemish women who received abnormal or inadequate primary screening results from 2014 to 2016...

BACKGROUND: The human papillomavirus (HPV) infection may affect the miRNA expression pattern during cervical cancer (CC) development. To demonstrate the association between high-risk HPVs and the development of cervix dysplasia, we examined the expression patterns of hsa-miR-194-5p and hsa-miR-195-5p in Pap smear samples from southeast Iranian women. We compared samples that were HPV-positive but showed no abnormality in the cytological examination to samples that were HPV-positive and had severe dysplasia...

INTRODUCTION: Liquid based cytology (LBC) has replaced conventional smear (CS) in the world. In this study, through a series with a large number of cases, we aim to make a comparison and general evaluation in all groups, primarily epithelial abnormalities, according to LBS and CS methods. This study was carried out in a private pathology laboratory located in a metropolitan city, where cytological materials sent from many clinics were examined. MATERIAL AND METHODS: There were 165,915 cases whose smears were examined between 2012 and 2020, most of them conventional (131,224 CS, 34,691 LBC)...

INTRODUCTION: Carcinoma cervix is the second most common cause of death in women worldwide and the most common cause in developing countries. Cervical cancer is considered a preventable gynaecological problem as it has a long premalignant stage which can be detected by exfoliative cytology like papanicolaou smear test. The papanicolaou smear test is a simple, safe, non-invasive, and low-cost effective method for screening cervical cancer in developing countries like Nepal. The aim of the study was to find out the prevalence of cervical papanicolaou smear test screening among patients visiting the Outpatient Department of Gynaecology of a tertiary care centre...

CONTEXT: SARS-CoV-2 virus causes COVID-19 by infecting nasal and oral cavities primarily by attaching its spike proteins to ACE 2 receptors expressed in epithelial cells. AIM: This study was done to evaluate the micronucleated cell count, metanuclear abnormalities, and genotoxic factor in exfoliated buccal mucosal cell among the COVID-19 suspected patients. SETTINGS AND DESIGN: This cross-sectional study was conducted at AIIMS, Mangalagiri, between August and October 2022...

It is thought that numerous genotypes of human papillomavirus (HPV) are associated with various atypical cells, such as multinucleated cells, koilocytes, binucleated cells, parakeratotic cells, and giant cells, in the cervix. We previously showed the specificity of HPV genotypes for koilocytes and multinucleated cells. Therefore, in this study, we analyzed the association among HPV genotypes and binucleated cells, parakeratotic cells, and giant cells in Papanicolaou (Pap) smears. We detected HPV genotypes and atypical cells in 651 cases of liquid-based cytology with an abnormal Pap smear...

BACKGROUND: Cervical cancer is a global public health problem with high mortality. Advances in screening programs for cervical cancer are considered key to eliminate cervical cancer. We aimed to examine the contribution of cell block analysis to the detection of epithelial cell abnormalities in cervical smear samples. METHODS: A total of 559 patients with suspected cervical pathology were examined, and their samples were analyzed by both liquid-based cytology (LBC) and cell blocks...

OBJECTIVE: Human Papillomavirus (HPV) persistence is considered the main risk factor for neoplastic progression, and evidence suggests that regulatory T cells play an important role in the failure of viral elimination. Regulatory T cells may be involved in maintaining a microenvironment favorable for viral persistence and neoplasticity, through a deregulation of the local immune response. The association between altered immune function and the development of chronic infections, cancer (solid and hematological), and autoimmune diseases is documented in the literature...

Pap smear screening is a widespread technique used to detect premalignant lesions of cervical cancer (CC); however, it lacks sensitivity, leading to identifying biomarkers that improve early diagnosis sensitivity. A characteristic of cancer is the aberrant sialylation that involves the abnormal expression of α2,6 sialic acid, a specific carbohydrate linked to glycoproteins and glycolipids on the cell surface, which has been reported in premalignant CC lesions. This work aimed to develop a method to differentiate CC cell lines and primary fibroblasts using a novel lectin-based biosensor to detect α2,6 sialic acid based on attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and chemometric...

Cervical cancer (CC) is the most prevalent gynecological malignancy and a leading cause of death among women. It is primarily caused by human papillomavirus (HPV) infection, with 99.7% of cases showing high-risk HPV genotypes. This study sheds light on HPV dynamics as well as the discrepancies of different CC screening modalities results while highlighting factors that may have contributed to such a scenario. Moreover, we underscore the importance of the non-viral etiology of CC as well. We examined the current trends of HPV infection and its effects on cervical health in women treated at a tertiary care center in Belgrade, Serbia...

OBJECTIVE: This study aims to investigate the implementation rate and influencing factors of confirmatory tests for women with abnormal cervical cytology results in the Korean nationwide cervical cancer screening program. METHODS: The National Health Insurance Service (NHIS) database was utilized to identify all Korean women who have participated in the Korean nationwide cervical cancer screening program from January 2011 and December 2021 using the NHIS database...

Cervical cancer is one of the leading health burdens globally with a huge incidence in developing countries like India. Cervical cancer has an extended premalignant stage known as cervical dysplasia or cervical intraepithelial neoplasia (CIN). CIN can be grade 1, 2, or 3 depending on its severity. One of the most effective methods of cervical cancer screening and prevention is detecting these premalignant lesions by cervical cytology. Pioneered by Dr. George Nicholas Papanicolaou, the Papanicolaou (Pap) stain became an important advent for the microscopic evaluation of the exfoliated cervical cells...

BACKGROUND: Endometrial aspiration (EA) is an economic, painless technique on an outpatient basis. Present study aimed at cytological evaluation of EA for (a) cellular yield and morphology and (b) utility of cell block (CB) and cytocentrifuge (CC) techniques. MATERIALS AND METHODS: EA samples were divided into two aliquots. Colorless samples were processed (1000 rpm × 6 min) for conventional smear (CS) and CC, both stained by Papanicolaou. Hemorrhagic samples were processed for CS and CB (paraffin embedding, hematoxylin-eosin stain)...

CONTEXT: The performance parameters of cervical cytology in any accredited cytology laboratory requires implementation of quality control exercise, which ensures acceptable performance by a laboratory. This study aims to assess the analytical aspect of quality control measures by evaluating the frequency and accuracy of epithelial abnormalities as detected in cervical Pap smears using histopathologic diagnosis as the gold standard. METHODS: A retrospective diagnostic test study from 2018 to 2020 was conducted...

Cervical cancer is the second most commonly seen cancer in women. It affects the cervix portion of the vagina. The most preferred diagnostic test required for screening for cervical cancer is the pap smear test. Pap smear is a time-consuming test as it requires detailed analysis by expert cytologists. Cytologists can screen around 100 to 1000 slides depending upon the availability of advanced equipment. It requires substantial time and effort to carefully examine each slide, identify and classify cells, and make accurate diagnoses...

Late diagnosis and the lack of screening methods for early detection define high-grade serous ovarian cancer (HGSOC) as the gynecological malignancy with the highest mortality rate. In the work presented here, we investigated a retrospective and multicentric cohort of 250 archival Papanicolaou (Pap) test smears collected during routine gynecological screening. Samples were taken at different time points (from 1 month to 13.5 years before diagnosis) from 113 presymptomatic women who were subsequently diagnosed with HGSOC (pre-HGSOC) and from 77 healthy women...
