In a retrospective study investigating primary glioma,seven patients developed delayed, treatment-relatedmyelodysplastic syndrome (tMDS) or acute myeloidleukaemia (tAML), after receiving treatment withlomustine, procarbazine, temozolomide and/or vincristine.
Four men and three women aged 34 to 69 years [seetable] underwent resective surgery, and all but onereceived radiotherapy, for a range of primary gliomas. Fiveof the patients subsequently received temozolomide indosages ranging from 6000–28 000 mg/m2, on a 5 dayschedule every 28 days. One received procarbazine[dosage not stated], and one received lomustine (total dose600 mg/m2)*, temozolomide and vincristine [dosage notstated](CTV regimen) followed by lomustine andtemozolomide (CT regimen). Primary glioma recurred in allbut one patient, and salvage therapy was undertaken in fiveusing temozolomide and procarbazine [dosages notstated]. Treatment continued for between 12 and36 months, and all patients recovered. Between 3 and31 months after the last chemotherapy exposure, tMDSwas diagnosed in all seven patients. There was complete orpartial loss of chromosomes 5 and 7, consistent withtMDS. In addition, three patients were diagnosed withtAML: one presenting within a week of confirmation oftMDS, and the other two presented 3 and 8 months afterthe diagnosis of tMDS. The syndrome manifested asanaemia (six patients), thrombocytopenia (four patients)and neutropenia (three patients).
Two of the patients with tMDS underwent bone marrowtransplantation; the remaining four received onlysupportive care. One patient died within a week ofdiagnosis because of cardiac complications of tAML,confirmed on autopsy. Follow-up ranged from 2 to12 weeks. Over that time, five patients died: two becauseof recurrent brain tumour, one as a complication oftransplantation (sepsis), and two as a result of tAML. At lastfollow-up, the remaining two patients were alive: one hadundergone transplantation and one had receivedsupportive care only.
Author comment: "[T]he present series serves to illustratea potential morbid adverse effect in treating glioma patientswith extended schedules of alkylator-based chemotherapyi.e., tMDS, tAML."
