Trial summary

As the most common subtype of liver cancer (85% ~ 90%), HCC is highly malignant; thus, one of the crucial issues in HCC management is an effective therapy for tumors at an early stage, which is vital for improving the prognosis of patients. Read more about this study

About this study

Official title: Microwave Ablation Versus Laparoscopic Hepatectomy for 3-5cm Hepatocellular Carcinoma: a Multicentre Retrospective Study

As the most common subtype of liver cancer (85% ~ 90%), HCC is highly malignant; thus, one of the crucial issues in HCC management is an effective therapy for tumors at an early stage, which is vital for improving the prognosis of patients. For ≤3cm HCC, ablation has been recommended by international guidelines as a first-line or alternative treatment because of similar survival outcomes and milder liver function injury with liver resection (LR). However, the appropriate treatment options for 3-5cm HCC remain controversial. Thus, none of the international guidelines recommend ablation as a first-line treatment for 3-5cm HCC. In the past few decades, treatment for HCC has tended to be less invasive, have fewer complications, and have higher cost-effectiveness. Compared with LR, laparoscopic Hepatectomy (LH) demonstrates the advancement of minimal invasion. As another minimally invasive technique for HCC, Microwave Ablation (MWA) has the potential to eradicate larger HCCs with larger coagulation areas and is less affected by the heat sink effect caused by vessels around the tumor. Many studies have identified the potential advantages of MWA over other ablation techniques. However, to date, no clinical studies have compared the efficacy of LH and MWA therapies for 3-5cm HCC with periodic progression.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Microwave AblationProcedure or surgery

    Also called Laparoscopic Hepatectomy

    Microwave Ablation: A minimally invasive technique for HCC, MWA has the potential to eradicate larger HCCs with larger coagulation areas and is less affected by the heat sink effect caused by vessels around the tumor.

    Laparoscopic Hepatectomy: The technique has been widely promoted worldwide with technical progress. In patients with cirrhosis, LLR has the potential advantage of reducing the risk of postoperative liver decompensation

Study groupRoleWhat they receive
Microwave AblationActive comparatorAccording to the shape, size and location of each patient's tumor, as well as the adjacent relationship with the surrounding organs, the individual MWA scheme was pre-established. Contrast-enhanced CT (CE-CT) or contrast-enhanced magnetic resonance imaging (CE-MRI) was used to evaluate complete ablation within 3 to 5 days after ablation. If radiography suggested incomplete ablation, supplementary ablation was performed as soon as the patient's condition permitted. A cooled-shaft MW system (KY-2000, Kangyou Medical, China) was used in the procedure.
Receives: Procedure: Microwave Ablation
Laparoscopic HepatectomyActive comparatorThe optimal surgical procedure for each patient depends on the characteristics of the tumor. Patients were placed in French position and a laparoscopic-assisted partial hepatectomy was performed under CO2 pneumoperitoneum pressure 12-14 mmHg (1 mmHg =0.133 kPa). In most cases, a 4-well or 5-well method was used under general anesthesia.
Receives: Procedure: Microwave Ablation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall survival

    OS was defined as death related to any cause and was indexed from the date of ablation or surgery until last contact or death

    Measured: More than 3 years

  2. Progession-free survival

    DFS was defined as the time interval between first treatment and recurrence or death, whichever occurred earlier.

    Measured: More than 3 years

Questions about this trial

What is this clinical trial studying?

A study testing Microwave Ablation in people with Overall Survival and Progression-free Survival, run by Chinese PLA General Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall survival (time frame: More than 3 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05796700, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Apr 2023.
