Trans-arterial chemo-embolization is safe and effective for very elderly patients with hepatocellular carcinoma

Figure 1 Survival curves comparing the age groups. Kaplan-Meier survival curves presenting the proportion of patients alive since hepatocellular diagnosis, stratified by age groups: < 65, 65-75 and ≥ 75 years. The survival curves are not statistically different (log-rank P = 0.19).

Figure 2 Laboratory results before and after trans-arterial chemoembolization procedures. A: Alkaline phosphatase (ALKP); B: Gamma-glutamyl transferase (GGT); C: Creatinine; D: Aspartate aminotransferase (AST); E: Alanine aminotransferase (ALT). Values before trans-arterial chemo-embolization (TACE) are in the x-axis, values after TACE are in the y-axis. In panels A, B, D and E, the vertical axis is in a logarithmic scale. In all panels the thick line represents y = x, the dashed line represents y = 2 × x and the thin line represents y = 3 × x. In all panels patients aged < 65 years are represented in circles, patients aged 65-75 years are presented with squares and patients aged ≥ 75 years are represented with triangles.
