BACKGROUND AND OBJECTIVES: There is limited information regarding the outcome of patients treated for leukemia during pregnancy. This study was performed on all cases of leukemia during pregnancy identified in our institution leukemia database. PATIENTS AND METHODS: It is a retrospective study from our existing database. Thirty two cases were identified among the cohort of patients treated for acute and chronic leukemia between January 1991 and July 2003. RESULTS: Among the acute leukemia patients (n=21), 10 patients (47.6%) received chemotherapy during pregnancy, seven had live birth and three had spontaneous abortion. No teratogenicity or congenital malformations or postnatal complication were reported. The remaining 11 (52.4%) were not given chemotherapy while pregnant; three patients presented after 34 weeks of gestation ending in normal live births and then received chemotherapy and eight patients had abortion before starting chemotherapy. Among the chronic myeloid leukemia (CML) patients (n=11), nine patients received hydroxyurea, one patient received alfa-interferon and one patient was treated with leukapheresis. Eight patients had normal live births and three patients had abortion. Out of the 32 patients, 18 patients (56.2%) subsequently underwent HLA matched sibling allogeneic stem cell transplantation, seven for acute myeloid leukemia (AML), two for acute lymphocytic leukemia (ALL) and nine for CML. After a median follow up of 16 years, five patients (15.6%) are alive in remission (one from chemotherapy group and four from SCT group). CONCLUSIONS: Our report lends credence to the safety and feasibility of administering anti-leukemic therapy in acute and chronic leukemias during pregnancy although acute leukemia patients had possibly a poor long term outcome compared to non-pregnant patients.
