Management of metastatic colorectal cancer (mCRC) of the liver presents a complex challenge to oncologists and multidisciplinary treatment teams.

Selective internal radiation therapy (SIRT) with SIR-Spheres^® Y-90 resin microspheres administered by interventional radiologists is an approved local therapy for the management of mCRC liver tumors.

• Approximately 92,000 doses have been administered in more than 1,230 treatment centres worldwide.
• New data from an array of large, multi-centre, international studies support expanded use of SIR-Spheres Y-90 resin microspheres in appropriate patients.

In First Line Treatment of mCRC:

• A post hoc analysis from two RCTs, SIRFLOX and FOXFIRE Global, indicates that the addition of SIR-Spheres Y-90 resin microspheres to chemotherapy in patients with the primary tumour originating from the right-side of the colon, significantly increases the overall survival (OS). These data were presented at European Society for Medical Oncology (ESMO) World Congress on Gastrointestinal Cancer (WCGIC), 2017.
• A retrospective analysis (REsect) of data from the first-line SIRFLOX study demonstrated a significant increase in potential resection of liver metastases when SIR-Spheres Y-90 resin microspheres were added to chemotherapy. The data from the REsect study were presented at the 12th International Congress of the European-African Hepato-Pancreato-Biliary Association (E-AHPBA), May 2017.
• Clinical studies in refractory mCRC have shown that SIR-Spheres Y-90 resin microspheres increase the time to progression and prolong overall survival.^1-3 In first-line treatment in mCRC, adding SIR-Spheres Y-90 resin microspheres to FOLFOX-based chemotherapy did not diminish patients' quality of life.^4,5

Beyond First Line Treatment in mCRC:

• Radioembolisation with SIR-Spheres Y-90 resin microspheres has demonstrated a clinically significant benefit in overall survival in multiple clinical studies, leading to the recommendation of SIRT with SIR-Spheres Y-90 resin microspheres by the ESMO and the NCCN clinical practice guidelines for colon cancer.
