Transplacental and Other Routes of Cancer Transmission Between Individuals

Abstract

Cancer in pregnancy is not rare, and the possibility of transmission of malignancy from mother to child, while infrequent, represents a clinical challenge for the primary pediatric hematologist-oncologist. The authors summarize all reported cases of vertically transmitted cancer and review other reported cases of person-to-person transfer of malignancy. As these cases represent a unique physiologic model of tumor transplantation, the biology of cancer transmission is discussed and provisional guidelines are given for the screening of infants born to women with cancer.
