The clinical effects of ultrasound-guided microwave ablation in the treatment of primary hepatic carcinoma: Protocol for a retrospective clinical observation

INSTRUCTION: Despite the continuous advancement of liver cancer diagnosis technology and level, there are still nearly two-thirds of patients with primary liver cancer that are already advanced at the time of diagnosis. Ultrasound-guided microwave ablation, as a palliative treatment for intermediate and advanced liver cancer, is currently recognized internationally Standard treatment for patients with unresectable hepatocellular carcinoma. However, recently, some scholars hold that ultrasound-guided microwave ablation does not guarantee complete inactivation of tumor lesions. METHODS/DESIGN: This study will evaluate the safety and effectiveness of ultrasound-guided microwave ablation in patients with advanced hepatocellular carcinoma through retrospective analysis. This study will follow a clinical research method with consecutive enrollment. The overall survival rate, objective tumor remission rate, serum indices and incidence of adverse effects after treatment will be counted for patients. DISCUSSION: At present, there are no good treatment options for intermediate and advanced hepatocellular carcinoma. Therefore, there is a strong demand to explore the individualized multidisciplinary combined treatment model based on ultrasound-guided microwave ablation.
