Local tumor progression after radiofrequency ablation of liver tumors: analysis of morphologic pattern and site of recurrence.
OBJECTIVE
The purpose of our study was to assess the morphologic pattern and exact site of local tumor progression with relation to various risk factors after radiofrequency ablation of liver tumors.


CONCLUSIONS
Local tumor progression after radiofrequency ablation shows mostly the peripheral nodular type. The site of local tumor progression shows a higher concordance rate with insufficient ablative margin than contiguous vessel and subcapsular location.
