Most patients present with intermediate or advanced disease that is not amenable to curative treatment, and the median survival in this group is 6-8 months (2). Several studies and well- designed randomized trials have shown a positive effect of transcatheter arterial chemoembolization (TACE) on patient outcome and survival (3-8). As nicely described in the present article from Wring et al., assessment of tumor response is of extreme importance in patients undergoing locoregional treatments of liver cancer (9). Early assessment of the effectiveness of TACE and monitoring of tumor response are paramount to the identification of treatment failure, guidance of future therapy, and determination of the interval for repeat treatment.展开更多

Unfortunately, a large percentage of patients present with metastasis at the time of diagnosis or relapse after a few months. The complex molecular heterogeneity of this disease is not completely understood; to date, there is a lack of predictive biomarkers that can be used to select subsets of patients who may respond to target drugs. Only the RAS-mutation status is used to predict resistance to anti-epidermal growth factor receptor agents in patients with m CRC. In this review, we describe approved targeted therapies for the management of metastatic m CRC and discuss new candidate targets on the horizon.展开更多
