[A case of liver failure associated with liver damage due to mFOLFOX 6 after resection for multiple liver metastases from colorectal cancer].

A case of colorectal cancer in a 60-year-old man became resectable after downstaging was achieved with mFOLFOX 6 for multiple liver metastases from colorectal cancer. The patient received 8 cycles of mFOLFOX 6 on the basis of a diagnosis of multiple liver metastases in the right and left lobes and a single metastasis in the right lung. After chemotherapy, the liver metastases showed partial response, and the lung metastasis stable disease. Because the lung metastasis was controlled and radical cure of the liver metastases was thought possible by resection, we performed right lobectomy of the liver. Postoperative progress was good, and we then planned a staged partial resection of the lung. However,on postoperative day 28, the patient was hospitalized again with liver dysfunction, which evolved into liver failure, in spite of conservative treatment. The patient died on postoperative day 95. The needle biopsy specimens of the liver taken on readmission showed bile duct occlusion, portal hypertension, and perisinusoidal fibrosis, and histopathology of the surgical non-tumoral liver specimen showed the same findings. We think that liver failure was triggered by resection of the liver which had been damaged by mFOLFOX 6. Recently, liver damage due to oxaliplatin was reported, and evaluation of liver injury is considered important before liver resection for colorectal liver metastases with neoadjuvant FOLFOX.
