Schwangerschaftsverlauf bei Patientinnen mit Malignomen

There is a low incidence of pregnancy associated with malignancy. We performed a retrospective analysis of patients of 16 to 35 years of age with malignancies, who had given birth to children in Freiburg 1980-1989. 170 patients were included. 118 patients became pregnant before a malignancy was diagnosed. Malignancy was diagnosed during pregnancy in 24 patients, and 28 patients became pregnant after diagnosis of and therapy for neoplasm. The frequency of preterm delivery, growth retardation and performance of Caesarean section was markedly increased only in patients with concurrent pregnancy and malignancy. 59 children were born after their mother had been treated for a malignancy. Treatment was started during pregnancy in 19 cases. 40 children were born to mothers who became pregnant after treatment. Malformations and abnormalities with respect to the development of the children were observed in similar frequency in both groups and occurred more frequently compared to the group of children, who were born before the treatment of the mother. These results were supported by an analysis of 16 siblings. We conclude, that there is a demand for national and international registries for all pregnancies associated with malignancies. Long-time observation of the children born to mothers, who had been treated for malignancy are necessary.
