Treatment related myelodysplasia (t-MDS) or acute myeloid leukaemias (t-AML)


The study included 9 cases; t-MDS with progression to AML accounted for 1 of 9 cases, and t-AML for the remaining 8 cases; no case of acute lymphoblastic leukaemia


t(8;16)(p11;p13) was found in 2% of t-MDS/t-AML; sex ratio: 5M/4F


Age at diagnosis of the primary disease 33 yrs (range 6-70); age at diagnosis of the t-MDS/t-AML: 41 yrs (range 7-71). Median interval was 17 mths (range: 13-202). Primary disease was a solid tumor in 9 of 9 cases; treatment was radiotherapy in 1 case, chemotherapy in 2 of 9 cases, or both (6/9). Treatment included topoisomerase II inhibitors in 6 of 8 cases and alkylating agents in 7/8.


Median survival was very poor: 5 mths, with 39% of patients surviving at 1 yr, and none at 2 yrs.

This data is extracted from a very large study from an International Workshop on treatment related leukemias - restricted to balanced chromosome aberrations (i.e.: -5/del(5q)and -7/del(7q) not taken into account per see), published in Genes,Chromosomes and Cancer in 2002.
