Survival probabilities from the time of diagnosis depending on the age: (A) Patients < 55 years: the median survival time of the 18 patients with 11q deletion was 64 months compared to 209 months in the 53 patients without 11q deletion. The difference between the two curves was highly significant (P < .001). (B) Patients ≥ 55 years: the median survival time of the 25 patients with 11q deletion was 94 months compared to 111 months in the 118 patients without 11q deletion (P = .82).
