Kaplan-Meier curves showing the expected survival in comparison to the observed LuTx-free (A) and observed overall (LuTx censored) (B) survival from the time of diagnosis. Patients at risk were n = 50, n = 47, n = 41, n = 32, n = 21, n = 16 and n = 14 at diagnosis, 12, 24, 36, 48, 60 and 72 months after diagnosis (observed survival). Level of significance: LuTx-free survival vs. expected survival: p = 0.15. Overall survival vs. expected survival: p < 0.01. |: censored patients.
