Objective: MicroRNAs (miRNAs) play critical roles in cervical carcinogenesis. Common single nucleotide polymorphisms (SNPs) in pre/pri-miRNAs may change their property through altering miRNAs expression and/or maturation. Here we aimed to investigate the influence of three common SNPs in pre/pri-miRNAs (pri-miR-26a-1 rs7372209, pre-miR-27a rs895819 and pri-miR-100 rs1834306) on individual susceptibility to cervical cancer.
Methods: We genotyped these three polymorphisms in 103 cervical cancer cases and 417 cancer-free female subjects using polymerase chain reaction-ligation detection reaction (PCR-LDR) method. Unconditional logistic regression analysis was utilized to estimate the association between these polymorphisms and the risk of cervical cancer.
Results: In a logistic regression analysis, we found that the rs895819 polymorphism in pre-miR-27a exhibited a significant effect on cervical cancer risk; T allele (OR = 0.68, 95% CI = 0.49-0.95, P = 0.025), and CT (OR = 0.33, 95% CI = 0.15-0.74, P = 0.007) or TT (OR = 0.33, 95% C I= 0.15-0.72, P = 0.006) genotype were associated with the decreased risk, compared to C and CC respectively. As we used further genotype association models, we found a similar trend of the association in additive (OR = 0.70, P = 0.041) and recessive model (OR = 0.33, P = 0.004). We did not detect any association of the other two SNPs in pri-miR-26a-1 (rs7372209) and pri-miR-100 (rs1834306) with cervical cancer risk.
Conclusion: Our study provides the first evidence that the miR-27a rs895819 polymorphism is associated with a decreased risk of cervical cancer in southern Chinese women.

This study examined the relationship between the vaginal microbiome, HPV infection, and cervical intraepithelial neoplasia (CIN) in 173 women. Subjects were grouped by HPV status and cervical lesion severity, ranging from HPV-negative to CIN Grade 2 or higher. Using VALENCIA classification, the study identified different community state types (CSTs) of vaginal microbiota, with CST IV subtypes (Staphylococcus dominated) showing high diversity and increased pathogenic bacteria.

Incorporating molecular testing for human papillomavirus (HPV) into the screening of cervical specimens can improve risk stratification and, in turn, patient management. Infection with a high-risk (HR) HPV genotype is associated with greater risk for persistent infection, viral integration, and progression of cervical neoplasia. Current guidelines consider HPV 16 or HPV 18 clinically actionable with referral to colposcopy; however, 12 Other HR HPV genotypes have been associated with cervical cancer risk, suggesting a benefit of extended genotyping.

Although breast, cervical, endometrial, and ovarian cancers account for more than 43% of new cases in 2023 in Brazilian women, no national studies were found on the incidence, risk factors, and prevention of breast and gynecological neoplasms in lesbian women, causing the health needs of non-heterosexual women to go unnoticed by professionals. This study aims to identify and analyze the search for healthcare related to the prevention of breast/gynecological cancer among Brazilian lesbian cisgender women who have not had the disease. Seven lesbian women participated in this qualitative study.

Objective: The goal of this study was to better understand the epidemiology, clinical characteristics, and treatment outcomes of head and neck sarcomas using real-world data from Japan.
Methods: Using the Japanese Head and Neck Cancer Registry, we identified 438 patients who were pathologically diagnosed with head and neck sarcoma between 2011 and 2020. We compared epidemiological, clinical, and prognostic data for the different histological types of sarcoma.

Purpose: Daily online adaptive radiotherapy (ART) improves dose metrics for gynecological cancer patients, but the on-treatment process is resource-intensive requiring longer appointments and additional time from the entire adaptive team. To optimize resource allocation, we propose a model to identify high-priority patients.
Methods: For 49 retrospective cervical and endometrial cancer patients, we calculated two initial plans: the treated standard-of-care (Initial) and a reduced margin initial plan (Initial) for adapting with the Ethos treatment planning system.
