We describe a relapsed AML patient who had two prior severe reactions to clofarabine involving rigors, emesis, tachycardia, hypotension, and acute kidney injury. Given previous prolonged remission achieved with clofarabine and cytarabine therapy years prior, rechallenge was undertaken upon discovery of AML relapse. We designed a desensitization protocol performed with the first dose of clofarab...

Acute myeloid leukemia (AML) remains a challenging disease to treat and urgently requires new therapies to improve its treatment outcome. In this study, we investigated the molecular mechanisms underlying the cooperative antileukemic activities of panobinostat and cytarabine or daunorubicin (DNR) in AML cell lines and diagnostic blast samples in vitro and in vivo. Panobinostat suppressed expres...

Primary cardiac lymphoma (PCL) is a rare subset of non-Hodgkin's lymphoma involving the heart and/or pericardium with no or minimal evidence of extracardiac involvement at presentation. Distant relapses have infrequently been observed. We report two cases of this disorder that showed isolated central nervous system (CNS) relapse. Diagnosis by endomyocardial biopsy was consistent with diffuse la...

Despite the apparent clinical benefits of high-dose cytarabine (Ara-C) over lower dose Ara-C in acute myeloid leukemia (AML) therapy, the mechanism behind high-dose Ara-C therapy remains uncertain. In this study, a LC-MS-based method was carried out to investigate the metabolic alteration of ribonucleotide and deoxyribonucleotide in human promyelocytic leukemia cells (HL-60) after treatment wit...

introduction : methotrexate (mtx) is an anti folate drug that used in malignant and non malignant patients. the usage of high dose methotrexate was limited to patients with: osteogenic sarcoma, ewing sarcoma and lymphoma. the aim this study was to determine the toxicity or side effects of very high dose methotrexate (8-10 gr/m 2 /cycle). this study is the first study in iranian patients and one...

We report a 31-year-old female with t(8;21)(q22;q22) acute myeloid leukemia (AML), M2 in the FAB classification. Complete remission was achieved with daunorubicin and cytarabine induction therapy followed by three courses of high-dose cytarabine consolidation. Only 3 months later, the patient relapsed with granulocytic sarcomas (GSs) in her rhinopharynx, external acoustic meatus, and bone marro...

Acute cerebellar syndrome can be caused by high doses of cytarabine, but it has not been described in patients with acute lymphoblastic leukemia (ALL) who received hyper-CVAD chemotherapy. Herein, we report two cases with histories of positive Philadelphia chromosome B-cell ALL who developed acute cerebellar syndrome after the exposure to relatively low doses of cytarabine in the second cycle o...

We read with interest the article presented by Mercadal et al. [1], a prospective trial of high-dose CHOP/E-SHAP (cyclophosphamide, vincristine, doxorubicin and prednisone/ etoposide, methylprednisolone, cytarabine and cisplatin) regimen followed by autologous stem-cell transplantation (ASCT) in high-risk peripheral T-cell lymphoma (PTCL), where the authors express their doubts about the contri...

BACKGROUND Cytarabine use during pregnancy carries a 5-7% risk of neonatal cytopenia. We report two cases of fetal myelosuppression following high-dose cytarabine administration for acute myeloid leukemia (AML). CASE 1 A 36-year-old G9P6 diagnosed with AML at 21 weeks was monitored for fetal anemia weekly and growth monthly. At 33 weeks (after 2 cycles), BPP was 2/10 and MCA PSV was elevated ...

We performed a retrospective analysis of 9 patients with acute myeloid leukemia (AML) treated with gemtuzumab ozogamicin (GO) plus cytarabine as a salvage regimen (GO reinduction) for patients who did not achieve complete remission (CR) after the first cycle of induction chemotherapy or at first relapse. Cases of AML secondary to myelodysplastic syndrome or myeloproliferative disorder were incl...
