RESUMO
Oral uracil and tegafur plus Leucovorin(UFT/LV)therapy is one of the standard adjuvant chemotherapies for colorectal cancer, and is widely used without any serious adverse events. Herein, we describe a case of UFT/LV-induced acute liver failure in a 75-year-old woman who underwent laparoscopic sigmoidectomy for sigmoid colon cancer. She was diagnosed with advanced colon cancer and lymph node metastasis by postoperative histopathological analysis, and adjuvant chemotherapy was initiated. After 30 days of commencing the therapy, the patient visited our hospital with complaints of severe diarrhea and difficulty in food intake. The apparent cause of these symptoms was unclear on computed tomography(CT), and mild liver damage was revealed in blood test results. The hepatic disorder gradually progressed after the hospitalization, and the condition was diagnosed as acute hepatic insufficiency. Additionally, obvious atrophy of the liver parenchyma and significant ascites were confirmed on CT. Two months later, the platelet count decreased markedly, but fortunately, no bleeding occurred. There has been no recurrence since 2 years after the surgery without any additional adjuvant therapy.

BACKGROUND/PURPOSE: Malnutrition and metabolic disorder of patients undergoing living donor liver transplantation (LDLT) can affect post-transplant prognosis. The aim of this study was to establish whether perioperative usage of branched-chain amino-acid (BCAA)-enriched nutrients improve metabolic abnormalities of patients undergoing LDLT. METHODS: We designed a randomized pilot study (UMIN registration number; 000004323). Twenty-five consecutive adult elective LDLT recipients were enroled and divided into two groups: the BCAA group (BCAA-enriched nutrients, n = 12) and the control group (standard diet, n = 13). Metabolic and nutritional parameters, including BCAA-to-tyrosine ratio (BTR), retinol binding protein (RBP), and prealbumin were regularly measured from 1 week before to 4 weeks after LDLT. Non-protein respiratory quotient (npRQ) was measured before and 4 weeks after LDLT. RESULTS: BTR and RBP improved considerably in the BCAA group compared with the controls. npRQ significantly increased from 1 week before LDLT to 4 weeks after LDLT in the BCAA group (0.77 ± 0.05 to 0.84 ± 0.06, P = 0.002), but not in the control group (0.78 ± 0.04 to 0.81 ± 0.05). CONCLUSIONS: Supplementation with BCAA-enriched nutrients might improve persistent nutritional and metabolic disorders associated with end-stage liver disease in the early post-transplant period, and consequently shorten the post-transplant catabolic phase after LDLT. A larger multicenter trial is needed to confirm these findings.
