Pregnancy outcome among long-term survivors with acute leukemia.

: By means of a mail questionnaire, we evaluated the influence of treatment for acute leukemia on offspring of long-term survivors and determined whether the outcome of pregnancy in patients (or spouses) induced relapse of acute leukemia. In 322 replies from the 445 institutions where a questionnaire was sent, there were 1136 adult long-term survivors. We analyzed the 43 adults who had become pregnant or become a father after postremission therapy. The mean age at the leukemia onset was 26.4 and 21.6 years for males and females. Forty-six normal children (26 boys and 20 girls) were born of long-term survivors including 7 pairs of siblings and a pair of twin sisters. There were no malformed babies. There were five abortions. The average duration until delivery was 79 months after diagnosis, and 49 months after the final postremission therapy. Four of 38 parents of live offspring died (3 relapse, 1 other disease), and the other 34 parents of live offspring were in complete remission at the point of this survey. The adverse effect of treatment on the offspring of long-term survivors could not be clarified in this survey. Additional lifetime follow-up of long-term survivors with acute leukemia and their offspring may be necessary.
