Pregnancy in Women with Metastatic Sarcomas

Successful pregnancy in women with metastatic cancer is rare in the published literature. We report here on four women with sarcoma who started and conducted their first pregnancies while in metastatic disease. All four pregnancies were first pregnancies, and all four women are long‐term survivors from 20 to 248 months after pregnancy. One patient had three pregnancies. All four women stopped systemic cancer treatment during their pregnancies, and two had RECIST progression during treatment interruption. Three patients still have unresectable metastatic disease, whereas one is in complete remission. In selected metastatic sarcomas with indolent courses, successful pregnancies are possible with no or minor impact on cancer progression and with prolonged life duration after pregnancy. As metastatic cancer becomes more often a chronic disease, this possibility opens important practical and ethical questions on how to best to advise women of childbearing age with metastatic cancers who are long‐term survivors.
