BACKGROUND: Cancer-related acute disseminated intravascular coagulation (DIC) is uncommon, but it is a severe complication resulting in a very dismal prognosis. Choosing the appropriate chemotherapy agents to treat the underlying cancer and stop the acute DIC process effectively, while avoiding chemotherapy-induced myelosuppression which may contribute to bleeding-related mortality, is difficult. Acute DIC in breast cancer is a rare condition and is not well studied. Therefore, we designed this study to determine the clinical characteristics and effective treatment for breast cancer patients with acute DIC. PATIENTS AND METHODS: From March 1996 to November 2008, patients with histologically proven breast cancer who presented with acute DIC at National Taiwan University Hospital were retrospectively analyzed. RESULTS: Sixteen patients were included in the study. Thirteen patients with breast cancer-related acute DIC were treated with various kinds of chemotherapy, one with tamoxifen, and two with supportive care only. Four patients responded to treatment; three of the responders received vinorelbine with high-dose 5-fluorouracil and leucovorin (HDFL), the other received vinorelbine with cisplatin. The median survival of the responders and non-responders was 13 months and 0.5 month (p<0.001). There were no grade 3 or 4 hematologic or non-hematologic toxicities in the patients receiving vinorelbine-HDFL. CONCLUSION: Vinorelbine plus HDFL is considered a safe and effective palliative treatment of choice for breast cancer patients with acute DIC. Further prospective study is warranted.
