Oxaliplatin-Induced Immune Thrombocytopenia in a Patient with Pancreatic Cancer.

UNLABELLED: Oxaliplatin-induced immune thrombocytopenia is a rare but potentially serious complication of chemotherapy. We present the case of a 55-year-old man with stage 4 pancreatic carcinoma who developed immune thrombocytopenia during the 18th cycle of folinic acid, fluorouracil, irinotecan, and oxaliplatin (FOLFIRINOX) chemotherapy, immediately after oxaliplatin infusion. Despite treatment with methylprednisolone and platelet infusion, the patient's platelet count remained low. Subsequent plasmapheresis and continued steroid therapy resulted in a gradual improvement in platelet count and resolution of symptoms. This case highlights the importance of considering immune thrombocytopenia in patients receiving oxaliplatin-based chemotherapy, and the potential role of plasmapheresis in refractory cases. Further research is needed to elucidate the optimal management of this rare complication.

LEARNING POINTS: Oxaliplatin-induced immune thrombocytopenia is a rare but potentially life-threatening side effect of chemotherapy.Management of drug-induced immune thrombocytopenia involves discontinuation of the offending drug and the use of steroids.Monitoring and follow-up are crucial in patients receiving oxaliplatin-based chemotherapy to promptly detect and manage potential hematologic emergencies, including immune thrombocytopenia.
