Design outcomes

Primary

MeasureTime frameDescription
Progression-free Survivalwithin 36 monthsKaplan Meier estimates of median progression-free survival according to the metastatic line of treatment, for a median follow-up of 18, 15 and 13 months, respectively

Secondary

MeasureTime frameDescription
Overall SurvivalUp to 36 monthsOverall Survival (OS) was defined as the time between the treatment start (date of the first infusion of bevacizumab) and death from any cause. Kaplan Meier estimates of median overall survival were calculated for the metastatic lines of treatment, with a median follow-up of 18, 15 and 13 months, respectively.
Quality of Life - Global Health StatusBaseline, 6 and 12 monthsParticipants rated their quality of life (global health status) on the European Organization for Research and Treatment of Cancer 30-item Core Quality of Life Questionnaire (EORTC QLQ C-30), with total scores ranging from 0 (worst) to 100 (best).
