Current treatment of lymphoma in pregnancy

Mediastinal Mass Discovered in the Second Trimester, a Rare Presentation of Hodgkin's Lymphoma in Pregnancy

Newly diagnosed malignancy during pregnancy is rare affecting approximately 1 in 1,000 pregnancies. Breast followed by hematologic malignancies are most common. Hodgkin's lymphoma (HL) is a lymphoid neoplasm which can present with lymphadenopathy or mediastinal mass and represents 6% of all malignancies diagnosed during pregnancy. Treatment involves a combination of chemotherapy with or without adjuvant radiation which poses significant challenges when diagnosed antepartum. We highlight a 28-year-old primigravida at 26 weeks gestation who presented to the emergency department in Japan with cough, dyspnea, and sore throat for 3-5 days. Initial chest radiography demonstrated a large perihilar mass with mediastinal shift. Follow-up CT chest revealed an anterior mediastinal mass measuring 8 cm × 19 cm × 16 cm with features concerning for aggressive lymphoma. The patient was subsequently transferred to a stateside tertiary care center for expedited workup. She underwent two core needle biopsies, both of which were non-diagnostic. Cardiothoracic surgery performed a cervical mediastinoscopy with excision of the enlarged right supraclavicular lymph node. Pathologic analysis revealed classical HL, nodular sclerosis subtype. Treatment was initiated with adriamycin, bleomycin, vinblastine, and dacarbazine with two cycles planned antepartum followed by additional cycles postpartum. The patient had an uncomplicated vaginal delivery at 38 weeks gestation. Diagnosis of HL in pregnancy is rare, and expedited diagnosis can be challenging as multiple diagnostic and treatment modalities may impact pregnancy. Management in pregnancy requires a multidisciplinary approach, and decisions regarding treatment and delivery timing should be weighed against risk to the fetus.

Lymphomas in pregnancy

Lymphoma in pregnancy is an uncommon occurrence. This diagnosis is challenging, and a multidisciplinary team of specialists in obstetrics, anesthesiology, neonatology, hematology psychology should participate in the management of this condition. The choice of treatment regimen depends on the histotype and the gestational age. In Hodgkin lymphoma, ABVD is safe if administered after the thirteenth week of pregnancy. In indolent non-Hodgkin Lymphomas (NHL) a watchful waiting approach is reasonable; in case of aggressive NHLs, if the diagnosis occurs in the first gestational weeks, a termination of the pregnancy might be considered or if it occurs after the thirteenth week of pregnancy, a standard R-CHOP regimen is safe. Regarding new anti-lymphoma drugs, available data on the potential fetotoxicity of these agents are limited. Data collection regarding the use of new drugs in pregnant patients is mandatory in order to learn more about their safety and facilitating clinical decision making in this setting of patients.

Imaging evaluation of lymphoma in pregnancy with review of clinical assessment and treatment options

Lymphoma-related malignancies can be categorized as Hodgkin's lymphoma (HL) or non-Hodgkin's lymphoma (NHL) based on histologic characteristics. Although quite rare during pregnancy, HL and NHL are the fourth and fifth most common malignancies during the pregnancy period, respectively. Given the rarity of lymphoma among pregnant patients, radiologists are usually unfamiliar with the modifications required for staging and treatment of this population, even those who work at centers with busy obstetrical services. Therefore, this manuscript serves to not only review the abdominopelvic imaging features of lymphoma in pregnancy, but it also discusses topics including birthing parent and fetal lymphoma-related prognosis, both antenatal and postpartum, current concepts in the management of pregnancy-related lymphoma, as well as the current considerations regarding birthing parent onco-fertility.

Unusual Presentation of Hodgkin's Lymphoma in Pregnancy: A Case Report and Systematic Review of Literature

Diseases occurring during pregnancy create a dilemma of managing the patient without causing harm to the unborn child. Three percent of the peak incidence of Hodgkin lymphoma (HL) is congruent with the reproductive period, particularly with pregnancy. Pregnant patients with HL always require a team of medical experts ranging from a medical oncologist, high-risk obstetrician, and neonatologist. Effective communication with both the patient and family is also necessary. The treatment goal for these patients should focus on achieving complete remission for the mother while permitting the delivery of a healthy child. Pregnant patients diagnosed with HL should undergo similar clinical investigations as other non-pregnant patients with accurate disease staging and appropriate non-radiation imaging such as ultrasound while avoiding invasive procedures.

Novel agents for the treatment of lymphomas during pregnancy: A comprehensive literature review

Lymphoproliferative diseases occurring during pregnancy present unique diagnostic and therapeutic challenges aiming to achieve maternal cure without impairing fetal health, growth, and survival. These goals are further complicated by the fast-paced emergence of novel therapies and their introduction as standard of care, even in newly diagnosed patients. Due to the rarity of hematological malignancies in pregnancy and the exclusion of pregnancy in almost all clinical trials, available data on the fetal effects of novel drugs are limited to animal models and case reports. The current review addresses the entire multidisciplinary team involved in treating pregnant patients with lymphoproliferative diseases. We describe novel agents according to their mechanism of action, and summarize our knowledge of their effects during the gestational period, particularly those associated with fetotoxicity. Therapeutic dilemmas associated with the employment of these new agents are also discussed.

Supportive medication in cancer during pregnancy

While pregnancy-related malignancies are quite rare, their incidence is increasing and thus affecting more and more women nowadays. Their management, however, with both chemotherapy and supportive agents remains quite challenging and it seems crucial to define the optimal treatment for this special population. Concerning supportive medication, it is clinically significant to determine whether commonly used agents, including Granulocyte Colony-Stimulating Factors, Erythropoiesis-stimulating agents, Bisphosphonates, Anticoagulation agents, Antiemetics and Glucocorticoids are indeed effective in ameliorating chemotherapy side effects. Meanwhile, it is of great importance that the administration of any of these agents is safe for both mother and fetus. This review aims to provide a précis of the current literature regarding both safety and efficacy of all categories of supportive medication during pregnancy.
