Treatment of myxoid liposarcoma in pregnancy.

Abstract

Two cases of pregnancy associated with myxoid liposarcoma are presented. Both patients were treated with hyperthermoradiotherapy after the induced delivery of healthy infants and by surgical excision of the tumor 5 to 7 weeks after delivery. No local recurrence or distant metastasis occurred; the children have progressed normally for 4 and 5 years, respectively, after surgery. Because coexistence of pregnancy and sarcoma is rare, it is difficult for the clinician to develop an appropriate approach to the management of bone and soft tissue sarcoma during pregnancy. The literature was reviewed regarding the effect that pregnancy may have on the clinical behavior of sarcoma and the effect treatment for sarcoma may have on the fetus.
