About this study

The purpose of this study is to assess the efficacy of Radiofrequency ablation (RFA) and percutaneous acetic acid ablation (PAI) in the management of small hepatocellular carcinoma (HCC) in patients of cirrhosis of liver.

Read the detailed description

Setting The study would be conducted at the All India Institute of Medical Sciences, New Delhi, a tertiary care teaching hospital, in the departments of Gastroenetrology and Radiodiagnosis.

Sample size Taking RFA as a standard procedure with an estimated success rate of 95%, a sample size of minimum 27 for each arm is required to detect an equivalence difference of 10%, assuming that PAI has a success rate of 85%. This sample size is expected to provide a power of 80%.

Randomization

  • Stratified randomization of Child A and B will be done.
  • Randomization into A (Acetic acid) and B (Radiofrequency ablation) will be done.

Diagnostic criteria

  • Cirrhosis of liver- Diagnosis will be founded on the basis of clinical, biochemical, imaging and endoscopy findings.

Hepatocellular carcinoma- when any one of the following is present

  1. Two imaging modalities (dual phase CT (DPCT)/ contrast enhanced Magnetic Resonance Imaging (MRI)) showing arterialization of the hepatic mass
  2. AFP more than 400ng/ml along with arterialisation on one imaging modality (DPCT/ contrast enhanced MRI)
  3. Fine needle aspiration cytology (FNAC)

Definitions

  1. Local recurrence : When the Triple phase CT shows-
  • An area of nodular enhancement that abuts or surrounds the ablation defect or protrudes into the low attenuating necrotic tissue (may sometimes be seen only on arterial phase of CT)
  • Recurrent soft tissue causing distortion of the otherwise smooth interphase with the adjoining liver parenchyma.
  1. Fresh lesion- When a new lesion is seen in the liver at a site other than the primary site of the treated lesion with normal liver parenchyma intervening in between will be considered as a fresh lesion.
  2. Residual disease or incomplete ablation When the follow up Triple phase CT shows-
  • Residual nodular enhancement that abuts or surrounds the low attenuating ablation defect or protrudes into the low attenuating necrotic tissue (may sometimes be seen only on arterial phase of CT)
  • Residual soft tissue causing distortion of the otherwise smooth interphase with the adjoining liver parenchyma.
  • Concenteric hyperemia around the low attenuating defect showing area of focal nodularity or asymmetric thickness.
  1. End point of ablation When the Triple phase CT shows-
  • A homogenous, well defined, uniformly low attenuating defect larger than the pretreatment size.
  • No residual soft tissue seen within or at the periphery of the low attenuating defect
  • Concentric hyperemia around the low attenuating defect of uniform thickness with no focal nodularity.

Follow up

  1. Clinical follow up
  • All patients would be followed up in the Liver clinic monthly unless their clinical condition warrants earlier follow up
  • Liver function tests/ complete blood count would also be done at each visit and Alfafetoprotein (AFP) every six months
  • Patient tolerance, child's status would be estimated.
  1. Imaging follow up
  • At one month, a dual phase CT would be done to ascertain the local response to therapy and the need to repeat the procedure. After achieving the end point after ablation (PAI and RFA, the DPCT would be done at 3 and 6 monthly intervals.

Duration of follow up - Since more than 80% recurrence occurs in 2 years therefore the duration of follow up would be 2 years after ablation.

What participants receive

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

  • PAIProcedure or surgery

    Under local anaesthesia, taking proper aseptic precautions, 40% acetic acid (total dose not exceeding 3 times the diameter of the mass, (not more than 2ml in one sitting), will be injected into the mass through the percutaneous route

  • RFAProcedure or surgery

    Under aseptic conditions and local anesthesia, the needle electrode would be introduced percutaneously into the tumor under ultrasound guidance.

What is being measured

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

  1. Local tumor response

    Measured: 2 years

Secondary outcomes (3)
  1. Survival rate

    Measured: 2 years

  2. Number of patients with complications

    Number of patients developing any complications during and after procedure will be noted.

    Measured: 2 years

  3. Change from baseline in Child status at 1 year

    Child status is calculated from the following 5 parameters

    1. Bilirubin < 2: 1, 2-3: 2 and > 3 : 3 points
    2. Albumin: > 3.5: 1, 2.8-3.5 : 2 and <2.8: 3 points
    3. Prothrombin time( seconds over control): 1-3: 1, 4-6: 2 and > 6: 3
    4. Encephalopathy: None: 1, (grade 1 and 2): 2 and (grade 3 and 4): 3
    5. Ascites: Absent: 1, slight: 2 and moderate: 3

    Child A: score 5-6, Child B: 7-9 and Child C: 10 or more

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing PAI and RFA in people with Hepatocellular Carcinoma, run by All India Institute of Medical Sciences at 1 site in India.

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 7 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 13 Jul 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in India. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Contact Subrat K Acharya, DM (01126594934, subratacharya2004@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Local tumor response (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 Jul 2012.
