Figure 1.

Disease-Free Survival (DFS): The delay of disease-free survival was calculated by the date of surgery until the date of revealing of a progress or until the date of death, or until the date of last news. The median duration of survival without progress is presented as well as the median follow-up and the rate of survival without progress in two years. N = 14 (12 events); Survival median: 5.7 months; Survival probability at two years: 28%
