Figure 2. Cytolytic activity of T cells measured by adenylate kinase (AK) release assay. AK release was quantifi ed by luminescence and expressed as RLU. A significant difference between patients with recurrence of malignancy and patients with disease-free survival is shown after 12 months (P < 0.05) only. Shown are mean ± SD. RFA: radiofrequency ablation; RLU: relative luminescence units
