Del (9q) is a recurrent cytogenetic abnormality in acute myeloid leukaemia (AML). We report an analysis of 81 patients with del(9q) as a diagnostic karyotypic abnormality entered into the Medical Research Council AML trials 10, 11 and 12. Patients were divided into three groups: (i) Sole del (9q), 21 patients; (ii) Del(9q) in association with t(8;21), 29 patients; (iii) Del(9q) in association with other cytogenetic abnormalities, 31 patients. Sole del(9q) was associated with a characteristic bone marrow phenotype at diagnosis: a single Auer rod was found in all cases examined. There was also an association with erythroid dysplasia (74%) and granylocytic lineage vacuolation (90%). The incidence of all three of these features was significantly higher (P < 0.05) in the sole del(9q) group compared with control cases lacking del(9q). The overall survival (OS) of all 81 patients was compared with a control group of 1738 patients with normal cytogenetics entered in the same trials over the period of investigation. The 5-year OS for patients with del(9q) was 45%, compared with 35% for the control group (P = 0.09). Patients with del(9q) in association with t(8;21) had a 5-year OS of 75%, which was significantly better than the groups with either sole del(9q) (40%) and del(9q) with other abnormalities (26%; P = 0.008). Karyotyping indicated a common area of deletion in the region 9q21-22, which was present in 94% of cases. It is likely that the deletion of single or multiple tumour suppressor genes located in this region may underlie the pathogenesis of del (9q) AML.
