BACKGROUND: Multiple primary lung cancer (MPLC) is becoming increasingly common in clinical practice. Imaging examination is sometimes difficult to differentiate from intrapulmonary metastasis (IM) or single primary lung cancer (SPLC) before surgery. There is a lack of effective blood biomarkers as an auxiliary diagnostic method. PARTICIPANTS AND METHODS: A total of 179 patients who were hospitalized and operated in our department from January to June 2019 were collected, and they were divided into SPLC with 136 patients, MPLC with 24 patients, and IM with 19 patients...

BACKGROUND: The efficacy of intersphincteric resection (ISR) surgery for patients with lower rectal cancer remains unclear compared to abdominoperineal resection (APR). The aim of this study is to compare the oncologic outcomes for lower rectal cancer patients after ISR and APR through a systematic review and meta-analysis. MATERIALS AND METHODS: A systematic electronic search of the Cochrane Library, PubMed, EMBASE, and MEDLINE was performed through January 12, 2022...

BACKGROUND: Obesity is associated with a significant predisposition towards cardiovascular events and acts as an important risk factor for mortality. Herein, we conducted a comprehensive meta-analysis to estimate the protective effect of bariatric surgery on disease-specific mortality and major adverse cardiovascular events (MACEs) in patients with severe obesity. METHODS: PubMed and Embase were searched from inception to 4 June 2022. Eligible studies were age, sex, and BMI-matched cohort studies...

OBJECTIVE: A prospective, multicenter, randomized controlled trial was conducted to explore the short-term effect of a new robotic-assisted total knee arthroplasty (TKA) system, and the clinical and radiographic effectiveness between the robotic-assisted system and conventional TKA were compared and analyzed. MATERIALS AND METHODS: Overall, 144 patients were randomly divided into two groups, wherein 72 patients underwent TKA using the robotic‑assisted system and 72 underwent conventional TKA...

BACKGROUND: Although the surgical treatment strategy for rectal cancer (RC) is usually based on the preoperative diagnosis of lymph node metastasis (LNM), the accurate diagnosis of LNM has been a clinical challenge. In this study, we developed machine learning (ML) models to predict the LNM status before surgery based on a privacy-preserving computing platform (PPCP) and created a web tool to help clinicians with treatment-based decision-making in RC patients. PATIENTS AND METHODS: A total of 6578 RC patients were enrolled in this study...
