Sequential use of transarterial chemoembolization and percutaneous cryosurgery for hepatocellular carcinoma

Figure 1 Survival rate of HCC patients.

Figure 2 Biopsy showing a HCC mass (11 cm × 9 cm) in the right liver lobe. The sequential changes (A-D) of the mass were disappeared after sequential therapy.

Figure 3 Histology showing the HCC mass at 3 mo (A) and 28 mo (B) after sequential therapy. The cryoablated mass had cavitation formation. No cancer cells were identified by needle aspiration.

Figure 4 A biopsy-proved HCC a female. A: A space-occupying lesion in right lobe of the liver after TACE and prior to the cryosurgery; B: The cryoablated lesion at 3 mo and 3 years, respectively, after cryosurgery; C: Needle aspiration showing liquefaction of the cryoablated lesion and no cancer cells; D: PET-CT showing no metabolic activity in the cryoablated mass 5 years after therapy.
