ABSTRACT
We report the data on 15 women who presented with Ph-negative acute lymphoblastic leukemia (ALL) between Jan 2009 until Dec 2016 and who were treated on the prospective multicenter RALL-2009 clinical trial. A comparison of their outcome was made with 129 non-pregnant females who entered the study and were treated by the same schedule. 10-years OS for pregnant and non-pregnant women was 58.6 % (29.6 %-85.0 %) and 43.3 % (32.1 %-58.8 %), DFS was 46 % (15.2 %-78.8 %) and 51 % (39.7 %-64.6 %); probability of relapse was 49 % (16.6 %-83.3 %) and 40.3 % (27.3 %-53.4 %), respectively. Twelve born during the study children are well and alive with a median age 5 years 2 months (2 years - 9 years). Though small, our study has shown some specific features of ALL diagnosed during pregnancy (more T-cell ALL, higher initial WBC, later responses) and has shown that the long-term outcome of women with ALL treated while pregnant is equivalent to female control patients treated on the same protocol.
