Abstract

Oxaliplatin-based chemotherapy plays an important role in the treatment of colorectal liver metastases. Oxaliplatin, however, causes sinusoidal obstruction syndrome (SOS), which is characterized by portal hypertension, splenomegaly, thrombocytopenia, and liver dysfunction. SOS is diagnosed histopathologically by disruption of the sinusoidal endothelium, collagen deposition, fibrosis especially around zone 3, dilatation of the sinusoidal space and congestion. This study assessed the characteristics of a rat model of SOS. SOS was induced in rats by administration of monocrotaline (MCT). Blood chemistries and macroscopic and microscopic findings were compared in rats administered MCT and vehicle (control group). Levels of expression in the liver of CD41, P‑selectin, rat endothelial cell antigen‑1, CD34, and cleaved caspase‑3 were analyzed immunohistochemically. Moreover, livers of these rats were analyzed by electron microscopy. Macroscopically, MCT‑treated rats showed accumulation of bloody ascites and blue liver and were diagnosed with SOS histologically. Serum concentrations of aspartate aminotransferase (P=0.003), alanine aminotransferase (P=0.008), total‑bilirubin (P=0.012), direct‑bilirubin (P=0.007), indirect‑bilirubin (P=0.003), lactate dehydrogenase (P<0.001) and hyaluronic acid (P=0.016) were significantly higher, and platelet counts significantly lower (P=0.004), in MCT‑treated than in control rats. The livers of MCT‑treated rats were immunohistochemically positive for CD41 and P‑selectin, suggesting platelet aggregates; for rat endothelial cell antigen‑1 and CD34, suggesting sinusoidal endothelial disorder; and for cleaved caspase‑3, suggesting hepatocyte apoptosis. Electron microscopic findings revealed platelet aggregation in the space of Disse in the MCT group. Extravasated platelet aggregation in Disse's space may be involved in the development of SOS.
