levoleucovorin and Hemorrhagic-Disorders

We report on a 65-year-old female patient with a recent diagnosis of adenocarcinoma of the sigmoid colon and massive hematochezia in the context of a general bleeding disorder.. Disseminated malignant disease with hepatic metastases as well as bone marrow involvement was demonstrated. Moreover, circulating tumor cells were demonstrated by flow cytometry. The patient had right lower quadrant abdominal pain due to a spontaneous psoas intramuscular hematoma.. At the time of admission to our hospital, the patient displayed microangiopathic hemolytic anemia and secondary hyperfibrinolysis with a pronounced bleeding tendency. Moreover, there was an acute renal failure which improved with fluid resuscitation. With immediate chemotherapy consisting of 5-fluorouracil, folinic acid and oxaliplatin (FOLFOX regimen) and cetuximab initiated with the second course, plasmatic coagulation could be stabilized. Consequently, treatment with tranexamic acid, fibrinogen, fresh frozen plasma as well as red blood cell and platelet infusions could be stopped. Continuation of chemotherapy was possible on an outpatient basis and the further course was associated with a good quality of life until her near end. The patient died at home 7 months after initial diagnosis of her colon cancer due to progressive disease with CNS metastases.. Disseminated intravascular coagulation with microangiopathic hemolysis and secondary hyperfibrinolysis is a rare albeit possible event in disseminated colorectal cancer, especially when the bone marrow is involved. Treatment of the underlying cause is the most important therapeutic measure.

Microangiopathic hemolytic anemia (MAHA) and disseminated intravasal coagulation (DIC) as initial paraneoplastic symptoms of a solid tumor present a rare clinical situation.. In 1998 a female patient was admitted due to multiple thrombosis, thrombocytopenia and fever. The initial diagnostic procedures revealed peri-aortic lymphomas and a tumor bulk (7 x 8 cm) in the upper abdomen. Gastroscopy revealed a 2 cm ulcer at the back side of the gastric corpus. Histologically, a signet-ring cell carcinoma was diagnosed. Final diagnosis stated a multilocular metastasising gastric cancer with infiltration of bone, peritoneum and dura and signet-cell infiltration of the bone marrow. Hematologic investigation in view of multiple paraneoplastic thrombosis revealed a microangiopathic hemolytic anemia associated with disseminated intravasal coagulation. Parallel to initial symptomatic therapy of coagulopathy, systemic cytostatic therapy with CDDP and VP-16 was initiated. In addition, radiotherapy of the brain was performed. After histologic confirmation of the diagnosis, weekly therapy with 5-FU (2600 mg/m2) and folinic acid (500 mg/m2) according to the Ardalan protocol was performed. After first signs of moderate response, oxaliplatin (60 mg/m2, day 1) was added. Although the chemotherapy dose had to be reduced due to prolonged neutropenia, the disturbances of hemostasis resolved completely resulting in reduced substitution rates with fresh frozen plasma (FFP) and platelets. Unfortunately, the patient died at home due to pulmonary embolism.. Tumor-associated hemostaseologic alteration requires immediate substitution of FFP and platelets. However, it should be followed by specific therapy of malignancy, since tumor-induced metabolites (e.g. mucin) maintain the alteration of hemostasis. Chemotherapy may therefore be the best strategy to prevent complications such as MAHA and DIC.
