SUN-289 Childhood-Onset, Adamantinomatous Craniopharyngioma and Successful Pregnancy: Results of Kraniopharyngeom 2000/2007

Background: Hypopituitarism is associated with an increased risk of pregnancy complications, such as abortion, anemia, pregnancy-induced hypertension, placental abruption, premature birth, and postpartum hemorrhage. The advance of assisted reproductive techniques makes it possible to improve the pregnancy rate in hypopituitary patients. Data on female fertility, pregnancy, and outcome of offspring after childhood-onset, adamantinomatous craniopharyngioma (CP) are rare. Study design: Observational study on pregnancy rate and outcome of offspring after childhood-onset CP in adult, female patients recruited in KRANIOPHARYNGEOM 2000/2007. Patient cohorts: Since 2000, 451 CP patients (223 f / 228 m) have been recruited with high grade of completeness. 263 CP patients (128 f / 135 m) have reached adult age. 6 of 128 adult, female CP patients (5%) reported on 9 pregnancies giving birth to 10 healthy newborns. Results: The median age at time of CP diagnosis was 14.9 years. Complete surgical CP resections were achieved in 3 patients. No patient underwent postoperative irradiation. 5 natural pregnancies occurred in 3 CP patients presenting with postoperative normal pituitary function. 4 pregnancies were achieved in 3 CP with hypopituitarism under assisted reproductive techniques (after in median 4.5 cycles, range: 3-6 cycles). Median maternal age at pregnancy was 30 years, ranging from 22 to 41 years. 6 of 10 babies were delivered by caesarean section. Gestational age at delivery was in median 38 weeks, ranging from 34 to 43 weeks; median birth weight was 2,920 gram (range: 2,270-3,520 gram), the rate of preterm delivery (<38 weeks of gestation) was 33%. The rate of breastfeeding was 56%. Enlargements of CP cysts occurred in 2 women during pregnancy. Other severe complications during pregnancy, delivery and postnatal period were not observed. Conclusions: Pregnancies after CP are rare (5%) and almost half of the patients (45%) achieved pregnancies after assisted reproductive techniques, which are effective and safe in CP patients. With regard to existing deficiencies of hypothalamic-pituitary axes, close monitoring and care by an experienced reproductive physician is necessary. Furthermore, MRI monitoring especially of CP cysts is recommended during pregnancy. Severe perinatal complications, birth defects, and postnatal morbidity of the mothers and their offspring were not observed. Most CP patients complained about their initial lack of information on potential fertility under assisted reproductive techniques.
