To Evaluate the Safety and Efficacy of Microwave Ablation Therapy in Patients With Primary Liver Cancer

Not Applicable
Conditions
Hepatocellular Carcinoma
Interventions
Device: microwave ablation
Registration Number
NCT04520906
Lead Sponsor
Suzhou Hengruihongyuan Medical Technology Co. LTD
Brief Summary

Through the implementation of prospective, multi-center, single-group target value research to verify the safety and effectiveness of the microwave ablation treatment system for the ablation treatment of primary liver cancer.

Detailed Description

The safety and effectiveness of the microwave ablation treatment system produced by Suzhou Hengrui Hongyuan Medical Technology Co., Ltd. for the ablation treatment of primary liver cancer is verified through the implementation of prospective, multi-center, single-group target value research. According to the requirements of the trial, 139 patients who were diagnosed with primary liver cancer before surgery and met the inclusion criteria without any exclusion criteria were selected for treatment of their liver cancer with a microwave ablation treatment system, 1 month, 3 months and 6 months after surgery Carry out clinical and imaging follow-up to evaluate the safety of the operation and the effect of tumor ablation.

Inclusion Criteria
  • Pathological and/or clinical diagnosis confirmed as primary liver cancer (hepatocellular carcinoma).
  • Single tumor with maximum diameter ≤ 5cm ; or tumors number ≤ 3 with maximum diameter ≤ 3cm.
  • No invasion of blood vessels, gallbladder, adjacent organs and distant metastasis.
  • Child-Pugh class A or B classification, or meet the standard after treatment.

  • Uncorrectable coagulation dysfunction (after corrective treatment, the PT exceeds the normal control value by more than 3s).
  • PLT <50x109/L.
  • Intractable massive ascites.
  • Cachexia.
  • MRI examination is contraindicated or the investigator judges it is not suitable for MRI examination.

Primary Outcome Measures
NameTimeMethod
Complete tumor ablation rate1 month after surgery

the percentage of complete ablation subjects for all subjects undergoing ablation surgery.

Complete ablation: Follow up by MRI scan 1 month after surgery, the area where the tumor is located is in the low-density arterial phase without enhancement; if the tumor is followed up by MRI scan 1 month after surgery, there is enhancement in the local arterial phase within the tumor lesion, which suggests that the tumor remains. The tumor could be treated by re-ablation; if there is still residual tumor in MRI scan 1 month after the second ablation, it is judged as incomplete ablation.

Secondary Outcome Measures
NameTimeMethod
First complete tumor ablation rate1 month after surgery

the percentage of subjects who did not undergo the second one month after the operation accounted for all the ablation trials.

Complete ablation rate of lesions1 month after surgery

the percentage of lesions that are completely ablated to all lesions undergoing ablation.
