HL During Pregnancy
Since Hodgkin lymphoma affects primarily young adults, most oncologists will eventually face the dilemma of how to provide therapy to a pregnant woman while minimizing the risk to the fetus. Treatment choice must be individualized, taking into consideration the mother’s wishes, the severity and pace of the Hodgkin lymphoma (HL), and the length of the remaining pregnancy. Since general guidelines can never substitute for clinical judgment, oncologists should be prepared to alter the initial plans when necessary.
Stage Information for HL During Pregnancy
To avoid exposure to ionizing radiation, magnetic resonance imaging is the preferred tool for staging evaluation. The presenting stage, clinical behavior, prognosis, and histologic subtypes of HL during pregnancy do not differ from those of nonpregnant women during their childbearing years. See the Stage Information for Adult Hodgkin Lymphoma (HL) section for more information.
Treatment Option Overview for HL During Pregnancy
HL that is diagnosed in the first trimester of pregnancy does not constitute an absolute indication for therapeutic abortion. Each patient must be looked at individually to take into account the stage and rapidity of growth of the lymphoma and the patient's wishes. If the HL presents in early stage above the diaphragm and appears to be growing slowly, patients can be followed carefully with plans to induce delivery early and proceed with definitive therapy. Alternatively, these patients can receive radiation therapy with proper shielding.[5-8] Investigators at M.D. Anderson reported no congenital abnormalities in 16 babies delivered after the mothers had received supradiaphragmatic radiation while shielding the uterus with five half-value layers of lead. Because of theoretical risks that the fetus might develop future malignancies from even minimal scattered radiation doses outside the radiation field, radiation therapy should be postponed, if possible, until after delivery.
Chemotherapy that is administered in the first trimester has been associated with congenital abnormalities in as many as 33% of infants.[11,12] However, in one series, there were no adverse effects in 14 children of mothers who received a combination of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) or a combination of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) during gestation, five of whom began treatment during the first trimester. Consequently, some women may opt to continue the pregnancy and agree to radiation therapy or chemotherapy if immediate treatment is required.
In the second half of pregnancy, most patients can be followed carefully and can postpone therapy until induction of delivery at 32 to 36 weeks.[11,14,15] If chemotherapy is mandatory prior to delivery, such as for patients with symptomatic advanced stage disease, vinblastine alone (given at 6 mg/m² intravenously every 2 weeks until induction of delivery) may be considered because it has never been associated with fetal abnormalities in the second half of pregnancy.[14,15] Steroids are employed both for their antitumor effect and for hastening fetal pulmonary maturity. As an alternative, a short course of radiation therapy can be used prior to delivery in cases of respiratory compromise caused by the rapidly enlarging mediastinal mass. Combination chemotherapy with ABVD appears to be safe in the second half of pregnancy. If chemotherapy is required after the first trimester, many clinicians prefer the combination of drugs over single-agent drugs or radiation therapy.
In one study, the 20-year survival rate of pregnant women with HL did not differ from the 20-year survival rate of nonpregnant women who were matched for similar stage of disease, age at diagnosis, and calendric year of treatment. The long-term effects on progeny after chemotherapy in utero are unknown, though present evidence tends to be reassuring.[12-16]
