RESUMO
A 27-year-old woman with newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia received induction therapy with dasatinib and prednisolone. From the time of diagnosis, oocyte storage was planned in accordance with the patient's wishes. After progesterone administration for suppression of menstruation, and blood cell recovery, ovarian stimulation was performed and a sufficient number of eggs was collected. The patient was considered at high risk for ovarian stimulation syndrome (OHSS) and received cabergoline and letrozole. However, ovarian enlargement and ascites were observed on ultrasonography 2 days after egg collection, and a diagnosis of moderate OHSS was made. Circulatory management was performed and low-molecular-weight heparin was administered. Dasatinib was discontinued due to the appearance of pleural effusion. Fluid retention improved after menstruation resumed, and the patient was able to continue consolidation with dasatinib and cord blood transplantation. Although tyrosine kinase inhibitors are expected to simplify planning of oocyte storage, the risk of complicating OHSS should be noted.
