Background: The purpose of this study was to describe the clinicopathological characteristics of breast DCIS in Chinese women and compare with that of patients in western countries.
Method: From December 2005 to December 2015, 617 women diagnosed with pure DCIS after surgery at our institution were enrolled, and the clinicopathological characteristics were described.
Results: In this study, the percentage of patients detected on screening, diagnosed at ≤50 years of age, with tumor size ≤2.0 cm, and with low-intermediate grade was 39.4%, 56.7%, 72.6%, and 77.4%, respectively, as compared to 50-80%, 20-30%, 70-90%, and 40-60% in published reports from western countries. The percentage of ER-positive patients was 76.3% in this study, which is similar to the mean expression rate of ER (mean: 68.7%, range: 49-96.6%) reported previously.
Conclusions: The clinicopathological characteristics of Chinese DCIS patients include less detection on screening, younger age at diagnosis, and more low-intermediate nuclear grade.

Purpose: Our study aims to evaluate the characteristics of serum soluble PD-1 (sPD-1) and soluble PD-L1 (sPD-L1) levels and their correlations with immune status and prognosis in advanced lung cancer patients.
Methods: Patients diagnosed with advanced lung cancer based on histology or cytology in Peking University People's Hospital from July 2020 to November 2021 were enrolled. Clinicopathological data were recorded and analyzed.
Clinical Value of Abnormal Prothrombin and Carbohydrate Antigen 125 in the Diagnosis of Patients With Gallbladder Cancer.

Department of Hepatobiliary and Pancreatic Surgery, East Hospital of Yantai Mountain Hospital, Yantai, China.
Objective: This study was aimed at ascertaining the application value of abnormal prothrombin (PIVKA-II) and carbohydrate antigen 125 (CA125) in gallbladder cancer (GBC) diagnosis.
Methods: A total of 70 GBC patients, 70 patients with benign gallbladder diseases (gallbladder stones and gallbladder polyps), and 70 normal health examination people were selected as the malignant, benign, and normal groups, respectively. The differences in serum levels and positive rates of PIVKA-II and CA125 were compared.
Clinicopathological Features and Prognoses of Patients With Splenic Metastases From Breast Cancer: A Single-Centre, Retrospective Study.
Cancer Control

Department of Medical Oncology, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital & Shenzhen Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Shenzhen, P.R. China.
Purpose: Splenic metastases (SM) from breast cancer (SMBC) are exceedingly rare. To date, the relevant literature is primarily based on pan-tumour species, with only a few studies exploring SM specifically in relation to breast cancer. As such, the present retrospective study explored the clinicopathological characteristics and prognoses of patients with SMBC at the breast care centre of the authors' hospital.

Background: To assess the effectiveness of tumor biomarkers in distinguishing epithelial ovarian tumors (EOTs) and guiding clinical decisions across each Ovarian-Adnexal Reporting and Data System (O-RADS) MRI risk category, the aim is to prevent unnecessary surgeries for benign lesions, avoid delays in treating malignancies, and benefit individuals requiring fertility preservation or those intolerant to over-extensive surgery.
Methods: A total of 54 benign, 104 borderline, and 203 malignant EOTs (BeEOTs, BEOTs and MEOTs) were enrolled and retrospectively assigned risk scores. The role of tumor biomarkers in diagnosing and managing EOTs within each risk category was evaluated by combining receiver operating characteristic (ROC) curves with clinicopathological characteristics.

Objective: Differentiated thyroid cancers tend to excellent long-term survival after surgery. However, Locally Advanced Papillary Thyroid Cancers (LAPTCs) have poor prognosis. This study was to investigate the clinicopathologic features of LAPTC and the risk factors that affect its postoperative recurrence.
