Are survival rates comparable after radiofrequency ablation or surgery in patients with small hepatocellular carcinomas?
Patients with small HCCs have a higher rate of tumor recurrence following RFA than surgery, but overall survival rates are comparable between therapies. RFA is as effective as surgery in patients with BCLC stage 0 HCC.
These findings suggested that poorer survival among African-American patients with adenocarcinomas of the colon may not be attributable to an advanced pathologic stage of disease at diagnosis, but instead may be due to aggressive biologic features like high tumor grades.
