6 months' follow-up in 16 (50%) patients, while at 12 months' follow-up this response decreased to 13 (40%) tumours. 6 (18%), patients showed approximately 60-90% reduction of arterialization, while only in 2 (0.06%) patients no response was observed and in one patient disease progression was observed at three months followup. Conclusions: In terms of the effect on the tumour response, combined TACE + PEI therapy was an effective in controlling the disease process.
