  • One month after treatment, complete necrosis was obtained in 95.7 % of the lesions < 2,5 cm, 76 % of the lesions ranging from 2.5 to 3.5 cm, and 54 % of the lesions > 3-5 cm (maximum 9 cm). Margins of necrosis were irregular but well delineated. Repeat treatment was performed when partial necrosis was achieved or when local recurrence or new lesions were observed. Major complications occurred in 7 patients with HCC: 3 liver abscess (with one death) and 4 seedings, one in patient with metastases.224 LIVER TUMORS (170 patients) Follow-up: 30 days after RFA
