Core Tip

Core tip: Different histological growth patterns (HGPs) of colorectal carcinoma (CRC) liver metastasis are associated with patients’ prognosis and response to antiangiogenic therapy. The aim of our study was to assess whether certain clinicopathological and genomic features of primary CRC could predict the HGPs of liver metastasis. We found that the HGPs, tumor budding score, and Crohn’s disease-like response of primary CRC as well as the presence of specific genetic mutations such as those in PIK3CA could be used to predict the HGPs of liver metastasis, response to therapy, and patients’ prognosis.
