  • Conclusions
    • Peri-operative chemotherapy with FOLFOX4 improved PFS in patients with resectable liver metastases, and even more in patients whose metastases were actually resected, and was safe.
    • This treatment should be proposed as the new standard for these patients, and should be delivered by a multidisciplinary team.

  • Overall Survival for patients with mCRC treated at MDACC and Mayo Clinic by year of diagnosis 2470 patients included in the registry in two highly specialized Centers In the last decade, overall survival in mCRC patients improved substantially Kopetz S et al, J Clin Onc 2009;27:3677-3683
  • Liver resection improved long term survival in specialized centers
    • OS by landmark analysis of those patients alive after 12 months following diagnosis
    70% of population included Liver resection dramatically improves long term survival and offers real chances for cure Kopetz S et al, J Clin Onc 2009;27:3677-3683 Median OS (m) OS at 5 years Resected pts 65.3 55% Non resected pts 26.7 19,5% HR 0.35
