Key clinical point: This analysis of more than 400 conceptions revealed that the rate of malformations was 2.5% in offsprings of fathers who did not discontinue tyrosine kinase inhibitors (TKIs) before conception, comparable to that measured in the general population.
Major finding: A total of 428 pregnancies from 374 fathers conceived without treatment discontinuation, 400 of which (93.5%) ended up in a live birth. Malformation was reported in 10 offsprings (2.5% of total live births): 6 with imatinib (1.9% of 313 live births), 2 with nilotinib (7.7% of 26 live births), 1 with dasatinib (2.3% of 43 live births), and none with bosutinib (0% of 12 live births).
Study details: A systematic review of 27 nonoverlapping cohorts of patients or case studies.
Disclosures: Study costs were covered by the Economic Development and Innovation Operative Programme Grant; Human Resources Development Operational Programme Grants; and the New National Excellence Programme, Ministry of Human Capacities. The authors declared no conflicts of interest.
