Successful treatment of primary extramedullary leukemia (EML) of the uterus with radical surgery, chemotherapy, autologous bone marrow transplantation (BMT) and prophylactic local irradiation.
Extramedullary myeloid cell tumors are rare manifestations of acute nonlymphocytic leukemia (ANLL). While many advances in diagnosis have been made, dilemmas remain concerning the treatment of this disease. In primary extramedullary leukemia (EML) most reports agree upon a local therapy followed by systemic chemotherapy such as is used for ANLL. However, further prophylactic local or systemic therapy with stem cell support remains controversial. A 20-year-old patient was diagnosed as having granulocytic sarcoma (GS) of the uterus without evidence of ANLL in 1991. After resection of the tumor at the uterine cervix and chemotherapy with daunorubicin 50 mg/m2 (days 1-3) and cytosine-arabinoside 200 mg/m2 (days 1-7) in September 1991, complete remission was achieved. In October 1991 cytosine-arabinoside 1000 mg/m2 every 12 h from day 1 to day 6 and amsacrine 200 mg from day 5 to day 7 were given as consolidation. Two years later relapse occurred in the adnexae. After radical hysterectomy, the same induction and consolidation chemotherapy was administrated. Subsequently, cytoxane 60 mg/m2 and fractionated total body irradiation (6 x 200 cGy) were given as conditioning and the previously cryopreserved bone marrow was reinfused. Finally, after hematopoietic engraftment, prophylactic local irradiation (4500 cGy) to the pelvis was given resulting in a disease-free long-term survival of more than 36 months after relapse. Although this experience is confined to one patient, it may contribute to the design of prospective therapeutic studies in patients with primary EML.
