Survival of patients with early hepatocellular carcinoma treated by percutaneous alcohol injection

Summary Background Once small (10 to ≤20 mm (n = 142, group B) and >20 to ≤30 mm (n = 272, group C). Overall and tumour‐free survivals were estimated by Kaplan–Meier method. Results In groups A, B and C, mean follow‐up was 33 ± 26, 34 ± 22 and 35 ± 25 months (P = 0.89), mean survival time was 63 ± 54, 57 ± 48 and 62 ± 66 months (P = 0.69) and mean tumour‐free survival was 44 ± 47, 46 ± 58 and 41 ± 68 months (P = 0.51), respectively. When patients were sorted by Child status, mean survival time was 76 ± 82 and 38 ± 29 months in Child A and B (P
