Influence of Cytogenetics on the Outcome of Patients With High-Risk Myelodysplastic Syndrome Including Deletion 5q Treated With Azacitidine With or Without Lenalidomide.

ABSTRACT: In myelodysplastic syndromes (MDS), cytogenetic characteristics of the malignant bone marrow cells influence the clinical course. The aim of this study was to evaluate whether cytogenetics is useful to predict outcome and response in patients with del(5q) under azacitidine (AZA) ± lenalidomide (LEN) therapy. We therefore performed comprehensive cytogenetic analyses in MDS patients with del(5q) treated within the randomized phase II trial NMDSG10B. Seventy-two patients were enrolled in the study and 46 patients (64%) had sufficient cytogenetics at inclusion and response evaluation. Karyotyping was significantly more sensitive during follow-up to detect del(5q) compared to FISH, 34 patients (97%) versus 27 patients (77%) (p = 0.027). The overall response rate (ORR) did not differ between the
