Effects of sigmoidoscopy screening (including colonoscopy) on colorectal cancer: A -analysis based on randomized controlled trials.

Background: This study aimed to investigate the role of endoscopy screening in colorectal cancer (CRC).

Methods: Up to January 2023, databases were searched for studies related to sigmoidoscopy and colonoscopy screening. The incidence of CRC, and/or CRC mortality were the main observation outcomes.

High-intensity focused ultrasound alone or combined with transcatheter arterial chemoembolization for the treatment of hepatocellular carcinoma with unsuitable indications for hepatectomy and radiofrequency ablation: a phase II clinical trial.

Objectives: This study aims to evaluate the efficacy and safety of high-intensity focused ultrasound (HIFU) alone or combined with transcatheter arterial chemoembolization (TACE) for patients with hepatocellular carcinoma (HCC) but were contraindicated for hepatectomy and radiofrequency ablation (RFA).

Methods: Patients between 20 and 80 years of age with 1-3 foci of HCC were selected. Included patients have had primary or recurrent liver lesions with no evidence of extra-hepatic metastasis prior to the study.
