The treatment of Hodgkin's and non-Hodgkin's lymphoma in pregnancy.
OBJECTIVE
Lymphoma is the fourth most frequent malignancy diagnosed during pregnancy, occurring in approximately 1 over 6000 deliveries.


METHODS
Its occurrence may increase due to the current trend to postpone pregnancy until later in life and the evidence suggested high incidence of AIDS-related non-Hodgkin's lymphoma in developing countries. The relatively rare occurrence of pregnancy-associated lymphoma precludes the conduction of large, prospective studies to examine diagnostic, management and outcome issues.


RESULTS
Chemotherapy and radiotherapy during the first trimester are associated with increased risk of congenital malformations and this risk diminishes as pregnancy advances. In the vast majority of cases, when lymphoma is diagnosed during the first trimester, treatment with a standard chemotherapy regimen, following pregnancy termination should be recommended. In the rare patients at low risk, such as those with stage 1 Hodgkin's lymphoma or indolent non-Hodgkins lymphoma, therapy can be delayed until the end of the first trimester and of embryogenesis while keeping the patients under close observation.


CONCLUSIONS
When lymphoma is diagnosed during the second and third trimesters, evidence exists suggesting that full-dose chemotherapy can be administered safely without apparent increased risk of severe adverse fetal outcome.
