Objective: The primary objective of this study was to identify the risk of metastasis to lymph nodes above the inferior mesenteric artery (IMA) in endometrioid-type endometrial cancer (EC) and the factors that influence metastasis.

Methods: The study included patients who had been operated on for endometrioid-type EC in three gynecological oncology centers between 2007 and 2023. The supramesenteric lymph node (SM-LN) is the region between the left renal vein and the IMA, whereas the inframesenteric lymph node (IM-LN) is the region between the IMA and the aortic bifurcation, as determined by the level of the IMA.

Oncogenic PIK3CA corrupts growth factor signaling specificity.

Mol Syst Biol

December 2024

Cell Signaling Laboratory, Department of Oncology, University College London Cancer Institute Paul O'Gorman Building, University College London, London, WC1E 6BT, UK.

Technical limitations have prevented understanding of how growth factor signals are encoded in distinct activity patterns of the phosphoinositide 3-kinase (PI3K)/AKT pathway, and how this is altered by oncogenic pathway mutations. We introduce a kinetic, single-cell framework for precise calculations of PI3K-specific information transfer for different growth factors. This features live-cell imaging of PI3K/AKT activity reporters and multiplexed CyTOF measurements of PI3K/AKT and RAS/ERK signaling markers over time.

Dysregulation of the expression levels and the activity of kinases/phosphatases is an intrinsic hallmark of tumor transformation and progression, as either as a primary cause or consequence. The myosin phosphatase (MP)/protein arginine methyltransferase 5 (PRMT5)/histone (H4) pathway is an oncogenic signaling pathway downregulating the gene expression of tumor suppressors. However, the upstream regulators of the pathway are unknown.

Aims: A significant proportion of locally advanced cervical cancer (LACC) patients experience disease progression post chemoradiotherapy (CRT). Currently existing clinical variables are suboptimal predictors of treatment response. This study reported a radiomics-based model leveraging information extracted from magnetic resonance (MR) T2-weighted image (T2WI) to predict the progression-free survival (PFS) for LACC following CRT.

Cervical cancer screening by biomarker-free Serum-SERS technique: A three-principal-substrate approach.

Biosens Bioelectron

December 2024

Key Laboratory of Advanced Materials (MOE), School of Materials Science and Engineering, Tsinghua University, Beijing, 100084, China. Electronic address:

The complexity of serum constituents and the lack of knowledge on biomarkers bring obstacles for reliable cancer screening with the limited information obtained by surface-enhanced Raman scattering (SERS) on a single substrate. We report here an extremely high-accurate approach for cancer screening by biomarker-free serum-SERS technique which employs three principal SERS substrates that are of specially designed surface properties. With three substrates rich information on serum can be obtained from SERS spectra, of which quadratic discriminant analysis (QDA) yields excellent classifications of serum samples independently.

Cancer Control

December 2024

Surveillance & Health Equity Science, American Cancer Society, Atlanta, USA.

Background: Cervical cancer (CCa) is the second most common type of cancer and a leading cause of death among adult women in Ethiopia. However, at the moment, there is a lack of evidence that can be generalizable as a whole to the country regarding the uptake of cervical cancer screening.

Objective: The aim of this review was to assess the pooled estimated uptake of CCa and to identify the major barriers to cervical cancer screening (CCS) uptake among adult women in Ethiopia.

Risk of High-Grade Cervical Dysplasia in Older Patients With a Positive Human Papillomavirus Cervical Screening Test.

J Low Genit Tract Dis

January 2025

Obstetrics and Gynaecology Department, Sunshine Hospital, Western Health, St Albans, Victoria, Australia.

Introduction: The Australian National Cervical Screening Program has mandated management algorithms that are uniform across all age groups, but evidence is emerging that perhaps the risk of high-grade squamous intraepithelial lesion (HSIL) may decrease in the postmenopausal period.

Objective: The aim of the study is to identify whether patients ≥50 years of age referred to a tertiary colposcopy service have a different risk of HSIL or greater (+).

Materials And Methods: This is a retrospective cohort study of 3239 referrals to a hospital colposcopy clinic with a positive human papillomavirus (HPV) cervical screening test between December 2017 and May 2023.

Objective: Endocervical curettage (ECC) is the gold standard for predicting the persistence of high-grade squamous intraepithelial lesions (HSIL) after cervical conization. However, ECC has a high rate of unsatisfactory samples and may be uncomfortable for women. Endocervical sampling with brush (ECB) has been proposed as an alternative to ECC, which, in addition to the cytological evaluation, allows performing HPV testing using the same sample.

Research has shown that the expression level of microRNA-155 (miRNA-155) is positively correlated with clinical stage and depth of invasion in patients with cervical cancer and cervical intraepithelial neoplasia and tends to be highly expressed. Therefore, it is very important to develop sensitive miRNA-155 analysis methods for the early diagnosis, treatment, and prognostic evaluation of cervical cancer. In this study, a near-infrared light-driven fluorescent biosensor based on the metal-enhanced fluorescence effect of polydopamine-coated upconversion nanoparticle (UP/Au) and two toehold-mediated strand displacement (TMSD) steps was constructed for the detection of miRNA-155.

Purpose: The immunosuppressive function of myeloid-derived suppressor cells (MDSCs) has been implicated in the regulation of immune responses against cancer and is associated with poor prognosis. Radiation treatment is known to alter immune cell populations within the tumor; however, whether this results in the recruitment of immunosuppressive MDSC populations is not well understood. Here we evaluate the response of circulating MDSC populations in patients treated per standard-of-care cisplatin chemoradiation therapy (CRT) for locally invasive cervical cancer.

Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC) is a biphasic epithelial tumor associated with HPV infection. This rare tumor primarily affects the nasal cavity and paranasal sinuses, with only two cases reported outside these locations to date-one in the breast and one in the vulva. This report presents a case of a tumor resembling an HMSC arising in the cervix.

Human papillomavirus (HPV) infections are sexually transmitted and contribute significantly to the spread of cancers in both men and women, including oropharyngeal and cervical cancers. The shortcomings of the current preventative strategies are becoming increasingly obvious, underscoring the need for new approaches, especially in the area of health education. Information accessibility, cultural appropriateness, proper management of information accuracy, and the spread of misinformation are emerging as critical focal points for improving the situation.

Laboratory of Molecular Translational Medicine, Center for Translational Medicine, Key Laboratory of Birth Defects and Related Diseases of Women and Children (Sichuan University), Ministry of Education, West China Second University Hospital, Sichuan University, Chengdu, Sichuan, 610041, P.R. China.

Background: Cervical cancer (CC) ranks as the fourth most common cancer and the fourth leading cause of cancer-related deaths among women globally, with declining incidence and mortality rates in recent decades. Previous studies have suggested that the transforming growth factor-beta (TGF-β) activated kinase 1 (TAK1) binding protein 2 (TAB2) can influence the stemness characteristics of squamous CC cells. However, the specific genetic impact of the TAB2 gene on CC remains unclear.
