Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Disease-free Survival (DFS)	Disease-free survival is defined as the time between date of surgery and first date of recurrence or death, whichever occurs first.Recurrence is defined as the appearance of one or more new lesions, which can be local, regional, or distant in location from the primary resected site ( assessed by imaging or pathology). All deaths without prior recurrence are considered as DFS events.	up to approximately 46 months
Secondary	Overall survival (OS)	Overall survival is defined as the time from date of surgery to date of death from any cause. For subjects that are alive, their survival time was censored at the date of last contact date (or "last known alive date").	up to approximately 46 months
Secondary	Overall Survival Rate	Overall survival rate is defined as the percentage of participants who are alive at 1, 2 and 3 years following surgery	From date of surgery to 1, 2 and 3 years later
