Bone marrow cultures and prognosis in primary myelodysplastic syndromes.

Abstract Bone marrow cultures and survival time were studied in 39 patients with primary myelodysplastic syndromes. We divided the patients into two groups according to the CFU-GM numbers on day 10: type I with low colony (CFU-GM in vitro growth type II (5 months) than it was for patients with an in vitro growth type I (>36 months). No relation was found between growth types and FAB-type, Bournemouth score or initial karyotype. The initial bone marrow blast percentage correlated well with the in vitro growth number.
