- W2590019071 abstract "8051 Background: Steatohepatits, otherwise known as fatty liver, has been associated with a number of chemotherapy agents, in particular the fluoropyrimidines. Chemotherapy Associated Steatohepatitis (CASH) can cause a number of clinical problems including misinterpretation of fatty liver for tumor progression and increased morbidity and mortality post liver resection (Kooby et al J Gastrointest Surg 2003). There has been no formal evaluation of the relative incidence of CASH with modern chemotherapy agents although a recent report suggests that oxaliplatin may be associated with hepatic sinusoidal obstruction (Rubbia-Brandt et al Ann Oncol 2004). Methods: We randomly identified 75 chemonaive patients from our institution that were treated with at least 2 months of either 5-fluorouracil and leucovorin (FU/LV) (n=25), irinotecan + FU/LV (n=25), or oxaliplatin + FU/LV (n=25) for advanced colorectal carcinoma (CRC). A quantitative assessment of CASH was performed by measuring Hounsfield units in 3 separate areas on the liver, spleen and paraspinal muscles respectively on pre and post chemotherapy computed tomography (CT) scans in each patient. Results: Attenuation measurements were performed on all 75 patients at a number of levels in the right lobe of the liver and at the closest corresponding levels of the spleen and muscle, immediately prior to and after administration of chemotherapy. Mean liver-spleen attenuation difference values were compared and those values which reduced by more than a predefined threshold value post chemotherapy were considered fatty. The results show 6 of 25 (24%) of the 5FU group, 12 of 25 (48%) of the CPT11 group, and 7 of 25 (28%) of the FOLFOX treated group showed attenuation differences consistent with interval development of diffuse fatty change in the liver. Conclusions: CASH can occur with modern chemotherapy agents. Verification of these results are necessary using more accurate measures of steatohepatitis such as non-contrast CT scans. With the increasing utilization of these agents for neoadjuvant therapy for advanced CRC, clinicopatholoigical studies are required to further characterize CASH and its potential complications.
