Primary Outcome Measures:
  • Response rate, defined as rate of patients without detectable metastases (after 1st-line treatment with or without surgery) [ Time Frame: approximately 4 years ]

Secondary Outcome Measures:
  • Clinical characteristics (diagnosis, treatments, comorbidities) of patients initiated on Avastin treatment [ Time Frame: approximately 18 months ]
  • Response (no detectable metastases after 1st-line treatment with or without surgery) according to clinical characteristics (number of cycles, chemotherapy, comorbidity) [ Time Frame: approximately 4 years ]
  • Progression-free survival [ Time Frame: approximately 4 years ]
  • Relapse-free survival after surgery [ Time Frame: approximately 4 years ]
  • Overall survival [ Time Frame: approximately 4 years ]
  • Histo-pathologic response (assessed at surgery) [ Time Frame: approximately 4 years ]
  • Treatment schedules (dosage, intervals, number of cycles) [ Time Frame: approximately 4 years ]
  • Safety: Incidence of adverse events [ Time Frame: approximately 4 years ]
