Hematologic neoplasms diagnosed during pregnancy, present significant
difficulties in patient management. Besides the strictly medical facts
, moral, ethical and religious issues shoud be strongly considered. Fo
r the optimal management of individual situations an integrated multid
isciplinary approach is mandatory. Hodgkin's disease, acute leukemias,
non Hodgkin's lymphoma and less frequently chronic myelogenous leukem
ia have been reported in pregnant women. Curative treatment for most o
f these diseases include intensive chemotherapy regimens. Potential da
mage to the fetus is a major concern, due to the teratogenic effects o
f antimetabolites, alkylating agents and radiation therapy. Effect of
pregnancy in each of these neoplasms is discussed. Although some rules
of management exist, dangerous generalizations should be avoided. Par
ticular obstetric considerations such as timing of delivery, and thera
peutic abortion should be carried out on an individual basis. The emot
ional impact of the situation must not be underestimated.
