Clinical presentation: Worsening fatigue associated with abdominal discomfort

Hospital course:
The patient, [Name], was admitted to the hospital at 36 weeks of gestation due to worsening fatigue associated with abdominal discomfort. The patient had a history of an uncomplicated cesarean delivery of a first child six years prior and was diagnosed with chronic myeloid leukemia (CML) one year ago. Despite initial treatment with imatinib 400 mg per day during the first and second trimester and interferon-α in the later half of pregnancy, the patient was found to have a palpable spleen and leukocytosis at 245,000WBC/mm3 including 32% blast cells.

Upon bone marrow aspiration, the patient was diagnosed with CML in acute phase with a karyotype of 46,XX,t(9,22)(q34;q11.2) in 100% of the analyzed cells. Due to the significant deterioration and urgent need for chemotherapy, a cesarean delivery was planned at the end of 36 weeks, which was uneventful under general anesthesia. Postoperatively, the patient received a multimodal analgesia and thromboprophylaxis.

Following the delivery, the patient was started on treatment with imatinib, 800 mg daily, without any satisfactory response. Palliative treatment with hydroxyurea was initiated due to disease progression resulting in partial response.
