This study demonstrates, for the first time, that TA enables a CFS of 12.2 months that extended to 20.9 months in patients who presented with lung-only metastases. TA is a viable option for a pause in the therapy of mCRCs.

Although rare, such an unusual pattern of liver metastasis may mimick acute cirrhosis and cause rapid hepatic failure in patients, despite possible apparent tumor regression on imaging. The etiology of this pathology is unclear, and may involve multiple pathogenic factors. Direct or indirect vascular injury plays an important role in the development of HLC.
