Article Abstract
Cervical cancer significantly affects women's health, while current preoperative imaging methods for predicting lymph node status are suboptimal. This study aims to evaluate the predictive value of CT attenuation (Hounsfield units) for lymph node metastasis (LNM) in cervical cancer patients and to develop a nomogram integrates clinical and imaging features to improve the accuracy of preoperative assessment. A retrospective analysis was conducted on 132 cervical cancer patients treated at the Second Affiliated Hospital of Dalian Medical University from January 2021 to August 2024. The cohort was divided into a training set (70%) and a validation set (30%) for constructing and evaluating the nomogram. CT attenuation was identified as robust predictors of LNM. Multivariate logistic regression showed that preoperative SCC levels, tumor histology, uterine corpus involvement, and lymphovascular space invasion were independent risk factors for LNM. The nomogram incorporating CT attenuation demonstrated excellent discrimination and calibration. This study presents a simple but robust nomogram that integrates clinical and imaging data to predict lymph node status in cervical cancer patients. The model exhibits high accuracy and reliability, highlighting the utility of CT imaging as a non-invasive preoperative tool for assessing LNM.

Purpose: Human papillomavirus (HPV) causes oral and anogenital cancers, the incidence of which is increasing. Late-stage diagnosis is associated with increased mortality. Neighborhood-level characteristics and distance to place of diagnosis may impact timely diagnosis.

Objectives: Treatment delay can adversely affect cancer prognosis and public health. However, previous studies have not examined the association between cancer treatment delay and 5-year mortality risk for various cancer types in a single study population.
Methods: We used retrospective cohort data from 21 740 patients diagnosed with common cancers between 2000 and 2017, with mortality follow-up to 2022, from the Philippines' Department of Health-Rizal Cancer Registry to understand how treatment delay of <30, 30-90, or >90 days was associated with 5-year all-cause mortality risk, by cancer type and stage at diagnosis.

Purpose: The fourth most common cause of cancer-related deaths in women is cervical cancer. Though treatment of early-stage cervical cancer is often effective, middle and advanced stage cervical cancer is hard to treat and prone to recurrence. We sought to explore the mechanism underlying cervical cancer progression to identify new therapeutic approaches.

Background: Metabolic reprogramming is an important hallmark of cervical cancer (CC), and extensive studies have provided important information for translational and clinical oncology. Here we sought to determine metabolic association with molecular aberrations, telomere maintenance and outcomes in CC.
Methods: RNA sequencing data from TCGA cohort of CC was analyzed for their metabolic gene expression profile and consensus clustering was then performed to classify tumors into different groups/subtypes.
