A: Tumor size was 3.5 cm × 3.2 cm before radiofrequency ablation (RFA) (2001-11); B: Tumor size was 3.2 cm × 3.1 cm at 12 mo after RFA (2002-12); C: Tumor size was 3.1 cm × 3.0 cm at 2 years after RFA (2003-11); D: Tumor size was 2.8 cm × 2.5 cm at 3 years after RFA (2005-1); E: Tumor size was 2.4 cm × 2.2 cm at 4 years after RFA (2005-11); F: Tumor size was 2.1 cm × 2.0 cm at 5 years after RFA (2006-09); G: Tumor size was 1.9 cm × 1.6 cm at 6 years after RFA (2007-11); H: Tumor size was 1.7 cm × 1.5 cm at 7 years after RFA (2008-11); I: Tumor size was 6.0 cm × 4.8 cm at 8 years after RFA (2009-12).
