Planned Pregnancy in Female Patients with Chronic Myeloid Leukemia Receiving Tyrosine Kinase Inhibitor Therapy

Conclusion.Planned pregnancy might be pragmatic in female patients with CML on TKIs. Achieving deep molecular response and, importantly, MMR duration ≥3.5 years were significantly associated with maintaining MMR during pregnancy.Implications for Practice.Female patients with chronic myeloid leukemia on tyrosine kinase inhibitors (TKIs) wishing to conceive are currently advised to discontinue TKIs before conception. However, the ideal degree and duration of response before stopping TKI, in addition to whether there will be any adverse effect caused by a short exposure of TKI, is unknown. Data of 17 female patients, who achieved at least a major molecular response (MMR) before TKI interruption, was revised, and it was found that achieving deep molecular response and MMR duration ≥3.5 years was significantly associated with maintaining MMR during pregnancy. This provides direct evidence for a planned pregnancy strategy, and stopping TKI immediately after determination of pregnancy in female patients might be pragmatic.

Abstract When breeding females compete for limited resources, the intensity of this reproductive conflict can determine whether the fitness benefits of current reproductive effort exceed the potential costs to survival and future fertility. In group-living species, reproductive competition can occur through post-natal competition among the offspring of co-breeding females. Spontaneous abortion could be a response to such competition, allowing females to curtail reproductive expenditure on offspring that are unlikely to survive and to conserve resources for future breeding opportunities. We tested this hypothesis u...

BackgroundChronic myeloid leukemia (CML) diagnosed during pregnancy is a rare situation with no standard treatment schemes. If a pregnancy is prolonged weighting the risks/benefits of therapy or observation without therapy is a complicated task. If a pregnancy is terminated a possibility of a further childbirth has to be judged. The course of the disease, treatment options and possible outcomes need to be known in these patients (pts) in the era of tyrosine kinase inhibitors (TKIs).Aim To describe pregnancy outcomes, therapy and follow-up in women with CML diagnosed during pregnancy in the era of TKIsMethodsWe made a searc...

Conclusions: Overall, a review of the available experience with bosutinib in pregnancy did not identify any safety signals. However, adverse effects of bosutinib exposure at conception or during pregnancy in humans cannot be ruled out, particularly if therapy is not interrupted upon recognition of pregnancy. Bosutinib is not recommended for use during pregnancy, and patients on bosutinib treatment should use effective contraception.DisclosuresCortes: Astellas Pharma: Consultancy, Research Funding; Novartis: Consultancy, Research Funding; Daiichi Sankyo: Consultancy, Research Funding; Pfizer: Consultancy, Research Funding; ...
