DISCUSSION
The presented data show that microwave ablation of HCC in selected octogenarians can be performed with
low morbidity and with results that are equal to those for septuagenarians, which was the primary aim of
the study.

This is well in line with previous findings by Shen et al. and Zhang et al. offering a potentially curative
treatment for octogenarians not deemed fit for surgical resection or as a first-line therapy.
