  1. Overall survival was modeled in weeks. A positive (negative) value of the estimate indicates that an increase (decrease) in the value of this variable is associated with favorable (unfavorable) overall survival outcome. The p value was obtained by Wald test (χ2). BTS baseline tumor size at randomization, TTG time to tumor regrowth
