Use and impact of selective internal radiation therapy (SIRT) in routine care patients with metastatic colorectal cancer (mCRC).

Abstract

742 Background: The liver is the dominant site of metastasis in patients (pts) with mCRC. Radioembolisation is a potential option in the multidisciplinary management of these patients. Recently initial analysis of a randomised controlled trial (RCT) in the 1st line setting demonstrated no overall progression free survival (PFS) benefit from adding SIRT, but prolongation of liver PFS (HR 0.69, p=0.002) was seen. Methods: Consecutive pts with mCRC enrolled from January 2009 were identified from a prospective multi-site Australian registry. Characteristics and outcomes for pts selected for treatment with SIRT were analysed. Results: Of 1,694 pts with mCRC, 580 (34.2%) had liver only disease at..
