translate into better long-term outcome and longer survival
of patients with primary and secondary liver tumors, but
it is indubitable that the technical improvement of MCT
systems is already ongoing. According to the conclusion
[1]
of the interesting review of Guan, we believe that MCT is
leaving its infancy and is running up to a quite rosy future.
