Background: Microangiopathic hemolytic anemia (MAHA) and disseminated intra
vasal coagulation (DIC) as initial paraneoplastic symptoms of a solid tumor
present a rare clinical situation.
Case report: In 1998 a female patient was admitted due to multiple thrombos
is, thrombocytopenia and fever. The initial diagnostic procedures revealed
peri-aortic lymphomas and a tumor bulk (7 x 8 cm) in the upper abdomen. Gas
troscopy revealed a 2 cm ulcer at the back side of the gastric corpus. Hist
ologically, a signet-ring cell carcinoma was diagnosed. Final diagnosis sta
ted a multilocular metastasising gastric cancer with infiltration of bone,
peritoneum and dura and signet-cell infiltration of the bone marrow. Hemato
logic investigation in view of multiple paraneoplastic thrombosis revealed
a microangiopathic hemolytic anemia associated with disseminated intravasal
coagulation. Parallel to initial symptomatic therapy of coagulopathy, syst
emic cytostatic therapy with CDDP and VP-16 was initiated. In addition, rad
iotherapy of the brain was performed. After histologic confirmation of the
diagnosis, weekly therapy with 5-FU (2600 mg/m(2)) and folinic acid (500 mg
/m(2)) according to the Ardalan protocol was performed. After first signs o
f moderate response, oxaliplatin (60 mg/m(2), day 1) was added. Although th
e chemotherapy dose had to be reduced due to prolonged neutropenia, the dis
turbances of hemostasis resolved completely resulting in reduced substituti
on rates with fresh frozen plasma (FFP) and platelets. Unfortunately, the p
atient died at home due to pulmonary embolism.
Conclusion: Tumor-asssociated hemostaseologic alteration requires immediate
substitution of FFP and platelets. However, it should be followed by speci
fic therapy of malignancy, since tumor-induced metabolites (e.g. mucin) mai
ntain the alteration of hemostasis. Chemotherapy may therefore be the best
strategy to prevent complications such as MAHA and DIG.
