Does “Conversion Chemotherapy” Really Improve Survival in Metastatic Colorectal Cancer Patients with Liver-Limited Disease?

Background The clinical benefits of conversion chemotherapy followed by liver resection for initially unresectable colorectal liver metastases are still controversial. The criteria for unresectability vary from one team to another. To clarify this issue, we retrospectively assessed the survival and characteristics of metastatic colorectal cancer (mCRC) patients with liver-limited disease (LLD) who underwent conversion therapy.
