[A Case of Disseminated Bone Marrow Carcinomatosis Arising from Breast Cancer for Which Paclitaxel and Bevacizumab Treatment Was Effective].

A 42-year-old woman visited our hospital with high fever and general malaise. A CT examination revealed that she had carcinoma of the left breast with axillary lymph node metastases and multiple bone metastases. A blood test showed anemia, thrombopenia and the existence of blast-like cells. Adenocarcinoma cells were detected in a bone marrow aspiration specimen, and the patient was diagnosed with disseminated carcinomatosis of the bone marrow. Systemic chemotherapy with paclitaxel plus bevacizumab was initiated while a blood transfusion was performed. Her symptoms improved, and the blood test results normalized. Disseminated carcinomatosis of the bone marrow is reported to have a poor prognosis, but paclitaxel plus bevacizumab is a possible effective chemotherapy.
