Background: As a commonly used biomarker in rectal cancer (RC), the prognostic value of carcinoembryonic antigen (CEA) remains underexplored. This study aims to evaluate the prognostic value of pretreatment CEA/tumor volume in RC.
Methods: This retrospective study included patients who underwent pretreatment magnetic resonance imaging (MRI) with histologically confirmed primary rectal adenocarcinoma from November 2012 to April 2018. Patients were divided into high-risk and low-risk groups according to the median values of CEA/Dia (CEA to pathological diameter), CEA/Dia (CEA to MRI tumor diameter), and CEA/Vol (CEA to MRI tumor volume). Cox regression analysis was utilized to determine the prognostic value of CEA, CEA/Dia, CEA/Dia, and CEA/Vol. Stepwise regression was used to establish nomograms for predicting disease-free survival (DFS) and overall survival (OS). Predictive performance was estimated by using the concordance index (C-index) and area under curve receiver operating characteristic (AUC).
Results: A total of 343 patients [median age 58.99 years, 206 (60.06%) males] were included. After adjusting for patient-related and tumor-related factors, CEA/Vol was superior to CEA, CEA/Dia, and CEA/Dia in distinguishing high-risk from low-risk patients in terms of DFS [hazard ratio (HR) =1.83; P=0.010] and OS (HR =1.67; P=0.048). Subanalysis revealed that CEA/Vol stratified high death risk in CEA-negative individuals (HR =2.50; P=0.038), and also stratified low recurrence risk in CEA-positive individuals (HR =2.06; P=0.024). In the subanalysis of stage II or III cases, the highest HRs and the smallest P values were observed in distinguishing high-risk from low-risk patients according to CEA/Vol in terms of DFS (HR =2.44; P=0.046 or HR =2.41; P=0.001) and OS (HR =1.96; P=0.130 or HR =2.22; P=0.008). The nomograms incorporating CEA/Vol showed good performance, with a C-index of 0.72 [95% confidence interval (CI): 0.68-0.79] for DFS and 0.73 (95% CI: 0.68-0.80) for OS.
Conclusions: Higher CEA/Vol was associated with worse DFS and OS. CEA/Vol was superior to CEA, CEA/Dia, and CEA/Dia in predicting DFS and OS. Pretreatment CEA/Vol may facilitate risk stratification and treatment decision-making.

Objective: The aim of this study is to evaluate the prognostic performance of a nomogram integrating clinical parameters with deep learning radiomics (DLRN) features derived from ultrasound and multi-sequence magnetic resonance imaging (MRI) for predicting survival, recurrence, and metastasis in patients diagnosed with triple-negative breast cancer (TNBC) undergoing neoadjuvant chemotherapy (NAC).
Methods: This retrospective, multicenter study included 103 patients with histopathologically confirmed TNBC across four institutions. The training group comprised 72 cases from the First People's Hospital of Lianyungang, while the validation group included 31 cases from three external centers.

Objective: To investigate the clinicopathological features, diagnostic value, risk model and prognostic significance of epithelioid hemangioendothelioma (EHE) in a retrospective cohort of 115 cases.
Methods: A total of 115 cases of EHE diagnosed in the Cancer Hospital of the Chinese Academy of Medical Sciences (NCC) from 2011 to 2023 were collected. The clinical and pathological features of EHE were reviewed by Fluorescence hybridization (FISH) and Immunohistochemistry (IHC).

This systematic review evaluates the comparative effectiveness of bariatric surgery versus medical therapy in managing obese patients with type 2 diabetes mellitus (T2DM). A decade-long literature search from January 2014 to January 2024 identified 10 randomized controlled trials (RCTs) involving diverse populations, interventions, and outcomes. The analysis demonstrates that bariatric procedures, such as Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and metabolic surgery, consistently outperform medical interventions, including GLP-1 receptor agonists, SGLT2 inhibitors, and intensive lifestyle modifications, in achieving superior glycemic control, weight reduction, and metabolic improvement.

Unlabelled: By integrating single-cell and bulk RNA-sequencing data for esophageal cancer (ESCA), we developed and validated a seven-macrophage-gene prognostic signature (FCN1, SCARB2, ATF5, PHLDA2, GLIPR1, CHORDC1, and BCKDK). This signature effectively stratified patients into high- and low-risk groups with significantly different overall survival, achieving area under the curve (AUC) values greater than 0.7 for 1-, 2-, and 3-year survival prediction.

Background: Hepatocellular carcinoma (HCC) prognosis continues to be challenging due to tumor heterogeneity and dynamic immunosuppressive microenvironments. Although pyroptosis plays a critical role in tumor-immune interactions, its prognostic significance in HCC at single-cell resolution has not been systematically investigated.
Methods: We analyzed a publicly available single-cell RNA sequencing (scRNA-seq) data from 10 HCC tumors and paired adjacent tissue samples (60,496 cells) to elucidate pyroptosis-related gene (PRG) profiles.
