Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Numerous studies find that anesthetic methods may influence the recurrence of tumor and the overall survival of patients after primary cancer surgery. Radiofrequency (RF) ablation is now widely used in the clinic for treatment of hepatocellular carcinoma (HCC). Currently, diverse anesthetic methods, including general anesthesia (GA), epidural anesthesia and local anesthesia (LA), are used for RF ablation surgery. Using serum from HCC surgery patients randomized to receive either GA or LA during surgery, we will investigate the effects of anesthetic methods on cellular invasion, migration and proliferation of HepG2 hepatic cancer cells in vitro. The expression levels of inflammatory cytokines in the serum from patients of both groups will also be analyzed.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients diagnosed with hepatocellular carcinoma (HCC) undergoing elective radiofrequency (RF) ablation surgery will be randomly allocated to general anesthesia(GA) group or local anesthesia(LA) group.

Patients from GA group will receive anesthesia induced with 0.05-0.1mg/kg intravenous midazolam, 3-6ug/kg fentanyl, 1.0-2.5mg/kg propofol and 0.1-0.2mg/kg atracurium. Laryngeal mask will be used to maintain ventilation. Anesthesia will be maintained with 4-8mg/kg/h propofol and 0.1-0.3ug/kg/min remifentanil, and additional non-depolarizing muscle relaxant when necessary. In patients from LA group, analgesia will be provided by a subcutaneous injection of 2% lidocaine by the surgeons before insertion of the needles.

Serum will be collected from patients of both groups at before induction and 1h post-surgery. The HepG2 hepatic cancer cell line will be treated with patient serum from both groups. The effects of anesthetic methods on cellular invasion, migration, proliferation will be measured. The expression levels of inflammatory cytokines in the serum from patients of both groups will also be analyzed.
