Successful chemotherapy management of disseminated intravascular coagulation presenting with metastatic clear cell renal carcinoma: a case report and review of the literature

BACKGROUND: Disseminated intravascular coagulation is a critical complication of advanced clear cell renal cell carcinoma, despite the rarity of the occurrence of disseminated intravascular coagulation in such tumors. The diagnosis of cancer-related disseminated intravascular coagulation is mostly based on clinical bleeding and laboratory test; available data suggest that treating the primary cancer also treats the disseminated intravascular coagulation. Among three reported cases of renal cell carcinoma-related disseminated intravascular coagulation in the literature, this is the first patient whose disseminated intravascular coagulation was successfully treated, in particular, with chemotherapy without any anti-disseminated intravascular coagulation therapies. CASE PRESENTATION: /L) without clinical bleeding. His past medical history and family history were unremarkable. An open-biopsy was performed and the definitive diagnosis was bone metastatic clear cell renal cell carcinoma based on immunohistochemistry. Two weeks after admission, the diagnosis of disseminated intravascular coagulation was confirmed according to the International Society on Thrombosis and Haemostasis. Immediately, he was treated with a paclitaxel plus carboplatin regimen and disseminated intravascular coagulation completely disappeared after one cycle of systemic chemotherapy. Until recently, 11 months subsequent to the diagnosis of disseminated intravascular coagulation, he had been being undergoing maintenance therapy for metastatic clear cell renal cell carcinoma. CONCLUSIONS: First, an early detection of overt disseminated intravascular coagulation is essential, although disseminated intravascular coagulation in cancer presents as a chronic or even subclinical process with unique thrombocytopenia. Second, making a decision of systemic chemotherapy without delay at the time of disseminated intravascular coagulation diagnosis is the key to successful cancer-related disseminated intravascular coagulation treatment.
