Oxaliplatin is a third-generation platinum compound that is commonly used for the treatment of colorectal cancer (CRC) both in the adjuvant and metastatic disease settings. Oxaliplatin-based chemotherapy is presently limited by cumulative dose-dependent neurotoxicity. We had previously reported on 2 patients who developed oxaliplatin-induced immune thrombocytopenia (OITP) during their tenth and seventeenth FOLFOX (5-fluorouracil/leucovorin/ oxaliplatin) cycles. Herein, we report on a third patient who developed severe thrombocytopenia after 28 cycles of modified FOLFOX6 (mFOLFOX) chemotherapy. A 60-year-old white woman with metastatic CRC, who had partial sigmoidectomy and colostomy, presented with bleeding from stoma site, on cycle 28, day 1 of mFOLFOX6, 7.5 hours after completion of the oxaliplatin infusion. Laboratory data revealed marked thrombocytopenia with a nadir platelet count of zero. Due to concern for OITP, the patient's serum was sent to BloodCenter of Wisconsin, Inc. (Diagnostic Laboratories; Milwaukee, WI). Serologic testing for oxaliplatin-dependent platelet antibodies was performed using flow cytometry in the presence of various concentrations of oxaliplatin. Laboratory tests for autoimmune hemolysis and disseminated intravascular coagulation (DIC) were negative. Oxaliplatin-dependent platelet reactive antibodies were detected in the patient's serum, confirming the diagnosis of OITP. The diagnosis of OITP should be entertained in patients receiving oxaliplatin for prolonged periods of time even though there are other more common causes of thrombocytopenia in these patients, including chemotherapy-induced myelosuppression, bone marrow involvement with tumor, and DIC.

Oxaliplatin in combination with a fluoropyrimide is a treatment option for colorectal cancer patients in the adjuvant and metastatic settings. Very few hematological emergencies have been reported associated with Oxaliplatin. These include autoimmune hemolytic anemia, thrombocytopenia and pancytopenia. We present a case report of a patient who developed hematuria and disseminated intravascular coagulation while receiving the second cycle of FOLFOX and bevacizumab for metastatic colon cancer.

Oxaliplatin is one of the most commonly used drugs for patients with colorectal cancer. It has rarely been associated with disseminated intravascular coagulation (DIC) with only 3 previously reported cases. In all those instances, the patients had started receiving oxaliplatin, developed evidence of DIC during the course of planned treatment, and recovered with supportive care. We report a case of a 71-year-old man with colorectal cancer treated successfully with an oxaliplatin-based regimen who had disease relapse after 3 years. When treated again with oxaliplatin, he developed signs of an acute hypersensitivity reaction, and eventually had signs and symptoms consistent with DIC despite appropriate management. This case is unique in that a DIC reaction evolving from a hypersensitivity reaction occurred after the patient had already tolerated the drug years earlier. It suggests a possible immune-mediated etiology to this rare occurrence that should be kept in mind while utilizing this commonly employed drug.
