Myelodysplastic syndrome and acute myeloidleukaemia: 4 case reports
In a retrospective study of 210 patients with chroniclymphocytic leukaemia, four patients were identified afterthey developed therapy-related myelodysplastic syndromeand acute myeloid leukaemia (t-MDS/AML) followingtreatment with antineoplastics [some dosages and routesnot stated].
Three men and one woman, aged 49–71 years, receivedsix cycles of FC chemotherapy, consisting of IV fludarabine25 mg/m2 and IV cyclophosphamide 200 mg/m2 for threeconsecutive days in each 28-day cycle. One man hadpreviously received two cycles of CHOP chemotherapy,consisting of cyclophosphamide, doxorubicin, vincristineand prednisolone, and four cycles of FND chemotherapy,consisting of fludarabine, mitoxantrone anddexamethasone. The female patient had received first-linetreatment with six cycles of CHOP chemotherapy. Theremaining two patients received FC chemotherapy as first-line treatment. At 7–56 months after completing FCtreatment, a diagnosis of t-MDS/AML was suspected in allfour patients. Morphological FAB types were M5b, M2,M4 and RAEB2. Two patients had trilineagemyelodysplasia, while three patients had complexkaryotypes and chromosome 5 abnormalities.
Three patients received intensive chemotherapy withdaunorubicin and cytarabine, while the remaining patient,with FAB type RAEB2, received low-dose cytarabine.Patient survival following t-MDS/AML diagnosis was1–8 months [outcomes not clearly stated].
Author comment: "[T]wo patients had received otherchemotherapeutic agents before FC – FND and CHOP in oneand CHOP in the other. Mitoxantrone . . . may contribute tothe DNA damaging effects of FC as suggested previously.Also, t-MDS/AML may occur after CHOP therapy, which ispotentially a confounding factor in both our patients treatedwith CHOP prior to FC."Colovic M, et al. Therapy-related myelodysplastic syndrome and acute myeloidleukemia in patients with chronic lymphocytic leukemia treated with fludarabineand cyclophosphamide.
