Аннотация
INTRODUCTION: Thrombotic microangiopathy (TMA) regroups the hemolytic and uremic syndrome (HUS) and thrombocytopenic thrombotic purpura (TTP). The TMA associated with cancer can be secondary to cancer, hence similar to TTP, or to chemotherapy, creating an HUS. Gemcitabine, used in the treatment of pulmonary, pancreatic and urothelial carcinomas, is generally well tolerated, but has recently been implied in the occurrence of TMA.
OBSERVATION: In a patient treated for a metastatic urothelial carcinoma, HUS developed after 8 cues of gemcitabine used alone. After symptomatic treatment and withdrawal of gemcitabine, the hematological abnormalities disappeared and renal function returned to preceding values.
DISCUSSION: The incidence of TMA is of around 5 to 6% of metastatic carcinomas. Gemcitabine-induced TMA are of recent occurrence and some twelve cases have been reported. Their occurrence is delayed with regard to the initiation of gemcitabine. They lead to HUS with good prognosis since, on withdrawal of gemcitabine the renal abnormalities regress. Search for TMA should therefore be proposed after more than 10 cycles of treatment with gemcitabine.
