major points
 Bevacizumab provides significant/superior PFS when
added to oxaliplatin-based chemotherapy regimens
 Treatment until progression is crucial to demonstrate
full potential of bevacizumab
 Analyses of withdrawal data and PFS on treatment
show excellent efficacy for bevacizumab
 IRC analysis clearly demonstrates superior PFS for
bevacizumab in all treatment groups

Surgery with curative intent in patients
receiving bevacizumab is feasible
 With appropriate management, bevacizumab can be used
in combination with chemotherapy with minimal risk of
bleeding/wound-healing complications in patients with
mCRC undergoing resection of metastases
 Data suggest that bevacizumab can be administered until
5 weeks prior to liver resection without any wound healing/
bleeding complications
 Liver generation following resection does not appear to be
affected in patients receiving bevacizumab in combination
with chemotherapy

Conclusions
 Bevacizumab combined with standard therapies is an
effective first-line treatment strategy for mCRC
 Bevacizumab is generally well tolerated
 Efficacy and safety outcomes in clinical evaluation
studies are similar to those reported in clinical trials
 Capecitabine is effectively replacing 5-FU in mCRC
 Data suggest that metastasectomy is feasible in
patients with mCRC treated with bevacizumab
plus chemotherapy
