Table 8

PFS and OS according to ATRX + DAXX and RB1 expression.

	ATRX + DAXX
	Negative ()	Positive ()
Median PFS (95% CI) (months)	6 (6-NE)	3 (2-NE)
Median OS (95% CI) (months)	6 (5-NE)	11 (5-NE)
	RB1
	Negative ()	Positive ()
Median PFS (95% CI) (months)	7 (2-NE)	3 (3-NE)
Median OS (95% CI) (months)	11 (6-NE)	6 (5-NE)

PFS: progression-free survival; OS: overall survival; CI: confidence interval; NE: not estimated.
