- BACKGROUND/AIMS: Hepatobiliary malignancies are frequently seen in primary sclerosing cholangitis (PSC) and they complicate the evaluation of patients and timing of liver transplantation. METHODS: Data from all Nordic PSC patients listed for liver transplantation during 1990-2001 were recorded prospectively. Predictors of hepatobiliary malignancy and patient survival rates have been analysed. RESULTS: Hepatobiliary malignancy was found in 52/255 (20%) patients accepted to the waiting list. Recent diagnosis of PSC, no ursodeoxycholic acid (UDCA) treatment, clinical suspicion and previous colorectal-cancer were predictors of malignancy. Among 89 patients with a strong suspicion of malignancy prior to acceptance, 35 (39%) had confirmed malignancy. A clinical suspicion had been raised in 35/52 (67%) patients with malignancy. Malignancy was found in 31/223 patients who received a liver allograft. The 1-, 3- and 5-year patient survival rates following transplantation for patients with PSC and cholangiocarcinoma were 65, 35 and 35%, respectively. CONCLUSIONS: Hepatobiliary malignancy is suspected in 1/3 of the PSC patients and found in 1/5. Although cholangiocarcinoma is regarded as a contraindication to liver transplantation (LTX), PSC patients with cholangiocarcinoma had a 35% 5-year survival following transplantation.

- Atypical hemolytic uremic syndrome (aHUS) is a thrombotic microangiopathy often caused by mutations in complement factor H (CFH), the main regulator of alternative complement pathway. Because CFH is produced mainly by the liver, combined liver-kidney transplantation is a reasonable option in treatment of patients with severe aHUS. We studied complement activation by monitoring activation markers during liver transplantation in two aHUS patients treated extensively with plasma exchange and nine other liver transplantation patients. After the reperfusion, a clear increase in all the activation markers except C4d was observed indicating that the activation occurs mainly through the alternative pathway. Concentration of SC5b-9 was higher in the hepatic than the portal vein indicating complement activation in the graft. Preoperatively and early during the operation, the aHUS patients showed highest C3d concentrations but otherwise their activation markers were similar to the other patients. In the other patients, correlation was found between perioperative SC5b-9 concentration and postoperative alanine aminotransferase and histological changes. This study explains why supply of normal CFH by extensive plasma exchange is beneficial before combined liver-kidney transplantation of aHUS patients. Also the results suggest that perioperative inhibition of the terminal complement cascade might be beneficial if enhanced complement activation is expected.

- The role of adjuvant systemic chemotherapy in liver transplantation (LT) for hepatocellular carcinoma (HCC) is controversial. Here, we report the results of a Nordic prospective, randomized, multi-centre trial of systemic low-dose doxorubicin in patients with HCC. Between February 1996 and April 2004, 46 patients were randomized to receive either neoadjuvant doxorubicin in combination with LT (chemo group; n = 19) or LT alone (control group; n = 27). In the chemo group, doxorubicin was administered intravenously, 10 mg/m(2) weekly, starting from acceptance onto the waiting list for LT. One intraoperative dose of 15 mg/m(2) was given, and postoperatively doxorubicin was given weekly at a dose of 10 mg/m(2), depending on the clinical course, up to a cumulative dose of 400 mg/m(2). Actuarial, 3-year overall survival (OS) and disease-free survival (DFS) in the control group were 70% and 50%, respectively. In the chemo group, both OS and DFS were 63%. Freedom from recurrence at 3 years was 55% in the control group and 74% in the chemo group. None of the differences was statistically significant. Neoadjuvant treatment with systemic low-dose doxorubicin seems not to improve either survival or freedom from recurrence in patients with HCC undergoing LT.
