AI Article Synopsis
- Preoperative prediction of lymphovascular space invasion (LVSI) in cervical cancer is vital for improving patient outcomes, and this study evaluates the effectiveness of combining amide proton transfer (APT) imaging with serum CA125 levels.
- The study included 80 cervical cancer patients, finding that the APT imaging had an AUC of 0.889 and CA125 levels had an AUC of 0.687 in predicting LVSI.
- The combination of APT and CA125 showed high diagnostic efficacy, with a sensitivity of 82.7% and specificity of 100%, indicating that this method is a valuable tool for predicting LVSI preoperatively in this patient population.*
Article Abstract
Background: Preoperative prediction of lymphovascular space invasion (LVSI) is crucial for improving the prognosis of patients with cervical cancer.
Purpose: To evaluate the value of preoperative amide proton transfer (APT) imaging combined with serum CA125 levels for predicting LVSI in cervical cancer.
Material And Methods: This retrospective study included 80 patients with cervical cancer who underwent preoperative magnetic resonance imaging, including APT imaging. Serum CA125 levels were measured using a fully automated immunoassay analyzer and chemiluminescence method. The presence of LVSI was determined based on the pathological results after surgery.
Results: Among the 40 patients who met the requirements, 29 had postoperative pathological confirmation of LVSI, while 11 did not. The areas under the receiver operating characteristic curves (AUC) of preoperative APT and CA125 levels predicting LVSI were 0.889 and 0.687, respectively. When the APT value was 2.9%, the corresponding Youden index was the highest (0.702), with a sensitivity of 79.3% and specificity of 90.9%. When the critical value of the preoperative serum CA15 level was 25.3 u/mL, the corresponding Youden index was the highest (0.508), with a sensitivity of 69.0% and a specificity of 81.8%. The sensitivity and specificity of preoperative APT imaging combined with serum CA125 in predicting LVSI were 82.7% and 100%, respectively, with a Youden's index of 0.828 and an AUC of 0.923.
Conclusion: The combination of preoperative APT imaging and serum CA125 levels is valuable for predicting LVSI in cervical cancer. Diagnostic efficacy is highest when the APT value is >2.9% and the serum CA125 level is >25.3 u/mL.

BACKGROUND Subchorionic hematoma (SCH) can lead to blood accumulation and potentially affect pregnancy outcomes. Despite being a relatively common finding in early pregnancy, the effects of SCH on pregnancy outcomes such as miscarriage, stillbirth, and preterm birth remain debated. This study aims to address these gaps by systematically evaluating the influence of SCH-related clinical factors on pregnancy outcomes using robust analytical techniques.

Introduction And Importance: Ovarian atypical proliferative mucinous tumor (APMT) is a low-malignant or borderline tumor that originates from the ovary's surface epithelium. This tumor can grow to a massive size, causing abdominal distention, which can result in a variety of compression symptoms if it is not discovered early.
Case Presentation: A 23-year-old female presented with a chronic, gradually developing abdominal distention that had been persistent for a year.

Aim: To establish a meaningful standard for diagnosing ocular metastasis (OM) in menopausal breast cancer (BC) women, and explore the relationship between CA-153, CA-125, apolipoprotein A, and OM.
Methods: A total of 1362 menopausal female BC patients with OM volunteered to take part in this study between July 2012 and July 2022. Women with BC who are menopausal were found to have an OM incidence of 1.

We aimed to detect the levels of T-lympho-cyte subsets and serum tumour markers in patients with non-small cell lung cancer (NSCLC) before chemotherapy, and to investigate the predictive value of their combined detection for the prognosis of NSCLC patients undergoing chemotherapy. The clinical data of 110 NSCLC patients treated with chemotherapy from January 2019 to February 2021 were analysed retrospectively. All patients were followed up for one year and divided into good prognosis group (surviving cases) and poor prognosis group (deceased cases).
