Treatment of Aggressive Non-Hodgkin’s Lymphomas in Pregnancy

Background. The management of aggressive lymphomas in pregnancy depends on the time of diagnosis and immunomorphological variant of tumor. The rarity of aggressive lymphomas in pregnant women, the absence of consistent approaches to the treatment of such patients, the lack of data on physical growth of children as well as the incidence of newborns’ congenital and acquired pathology make this subject of vital importance.

Aim. To analyze the treatment results in patients with newly diagnosed aggressive lymphoma at different stages of pregnancy.

Materials & Methods. From 1993 to 2020 at the National Research Center for Hematology 74 pregnant women with lymphomas were treated. Aggressive tumors were detected in 17 (23 %) of them: primary mediastinal (thymic) large B-cell lymphoma (n = 14), anaplastic large-cell lymphoma ALK+ (n = 1), high-grade B-cell lymphoma, unspecified (n = 1), and diffuse large B-cell lymphoma (n = 1). The median age of patients was 30 years (range 21–37 years). The median pregnancy stage on the diagnosis of aggressive lymphoma was 21 weeks (range 11–32 weeks).

Results. In 1 case on the diagnosis of aggressive lymphoma at 11 weeks gestation dexamethasone 8 mg daily was administered up to the second trimester of pregnancy, afterwards the patient received polychemotherapy. On the diagnosis of aggressive lymphoma in the second (n = 13) and third (n = 2) trimesters of pregnancy the patients received polychemotherapy followed by delivery. In the third trimester of pregnancy delivery was performed with subsequent polychemotherapy in 1 patient. There were born 18 babies (1 pregnancy was multifetal): 8 girls and 10 boys.

Conclusion. As a result of the chosen tactics and the work of interdisciplinary team of doctors all patients, who completed the treatment, are followed-up in complete remission. All born babies, despite chemotherapy and perinatal complications, are alive and develop without abnormalities.
