Arm Intervention/treatment
Active Comparator: Percutaneous acetic acid Procedure: PAI
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

Active Comparator: Radiofrequency ablation Procedure: RFA
Under aseptic conditions and local anesthesia, the needle electrode would be introduced percutaneously into the tumor under ultrasound guidance.

Primary Outcome Measures :
  1. Local tumor response [ Time Frame: 2 years ]

Secondary Outcome Measures :
  1. Survival rate [ Time Frame: 2 years ]
  2. Number of patients with complications [ Time Frame: 2 years ]
    Number of patients developing any complications during and after procedure will be noted.

  3. Change from baseline in Child status at 1 year [ Time Frame: 2 years ]

    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
