Core Tip

Core tip: Drug induced hepatic steatosis is a rare form of liver injury. Although hepatic steatosis has been observed in some patients with pancreatic cancer who were administered S-1, the ability of 5-fluorouracil alone to induce hepatic steatosis has not been evaluated systematically. The purpose of our study was to determine whether S-1 induces hepatic steatosis in patients being treated for pancreatic cancer. After analyzing a total of 22 patients, we found that S-1 chemotherapy induced hepatic steatosis in some patients with pancreatic cancer within three months and the correlation between the development of hepatic steatosis and liver function was weak in these patients.
