We report a case of bone marrow carcinomatosis with disseminated intravascular coagulation (DIC) originating from metastatic breast cancer that was treated with paclitaxel plus bevacizumab. A woman in her 30s was diagnosed with bone marrow carcinomatosis arising from metastatic breast cancer 2 years previously. Pathologically, estrogen receptor (ER) and progesterone receptor (PgR) -positive and human epidermal growth factor receptor 2 (HER2/neu) -negative scirrhous carcinoma was diagnosed. She improved after treatment with paclitaxel plus bevacizumab and zoledronic acid. Subsequently, she was treated with hormonal therapy (tamoxifen plus luteinizing-hormone-releasing hormone [LH-RH] agonist) for 7 months. because progressive bone metastasis was identified and tumor markers increased, the patient was administered paclitaxel plus bevacizumab again. Fifteen days after chemotherapy was initiated, DIC developed. Chemotherapy was continued without decreasing the dose, and recombinant human soluble thrombomodulin (rTM) was added. The DIC resolved in 5 days. After 6 courses of paclitaxel plus bevacizumab, improvement of tumor markers and bone metastasis was observed. Paclitaxel plus bevacizumab can be effective for treatment of bone marrow carcinomatosis with DIC originating from metastatic breast cancer.
