Prognostic factors in patients with acute liver failure undergoing live donor liver transplantation.

Mortality from acute liver failure (ALF) is high. Live donor liver transplantation (LDLT) is the treatment of choice for ALF in Asia, because cadaveric donors are rare. We sought to review our results in ALF patients with undergoing LDLT at our center. One hundred two LDLTs were performed at our center from April 2002 to November 2007, 15 (14%) because of ALF. Mean (SEM; median, range) follow-up was 1,065 (189; 1400; 3-2046) days. Nine patients (60%) had acute exacerbation of chronic hepatitis B; and 6 (40%) had drug-induced liver injury. Age was 47 (3; 50; 27-65) years. Ten patients (67%) were men. At transplantation, laboratory values were included bilirubin, 449 (35) micromol/L; creatinine concentration, 182 (32) mmol/L. The international normalized ratio was 2.4 (0.2). The Model for End-Stage Liver Disease (MELD) score was 34 (2). Both inpatient and long-term mortality was 20% 3 of 15 patients died. The 5-year survival was 80%. Compared with survivors, patients who died had a significantly higher creatinine concentration 289 vs 155 micromol/L, international normalized ratio (3.4 vs 2.1), MELD score (47 vs 32). We conclude that despite being sick with median and mean MELD scores of 32 and 34, 80% of patients with ALF can achieve good long-term survival after LDLT.

Experience of the transplant team is an important factor for posttransplant survival in patients with hepatocellular carcinoma undergoing living-donor liver transplantation.

Living-donor liver transplantation (LDLT) is an effective treatment for patients with unresectable hepatocellular carcinoma (HCC). However, it remains controversial whether expanded listing criteria can be used for LDLT. We aimed to review results of LDLT for patients with HCC at our center. Patients with HCC were accepted for LDLT if there was no extrahepatic spread on computed tomography (CT) and positron emission tomography CT scan. Transarterial chemoembolization was performed before LDLT to control the tumors. Sirolimus or everolimus was used as part of the immunosuppressive protocol for all patients. Over the last 6 years, 35 of the 102 (34%) LDLT were performed at our center for HCC. Age (mean +/- SEM) was 55.3 +/- 1.3 years; 28 patients (80%) were men. Eight (23%) had LDLT performed in 2002 or 2003 (period 1), and 27 (77%) in 2004 to 2007 (period 2). Eleven (31%) were within and 23 (69%) were outside the Milan criteria. After 583 +/- 76 days follow-up, nine (25%) died, three of recurrent HCC. Three-year survival was significantly better in period 2 than in period 1 (90% vs 13%; P < .001). Although the 3-year survival for those within Milan criteria was better than those outside Milan criteria, the difference did not reach statistical significance (86% vs 57%; P = .26). Six (17%) had HCC recurrence, of whom five died. We concluded that reasonable medium-term survival can be obtained for patients with HCC. The experience level of the transplant team seemed to be the most important predictor of patient outcome.

Follicular dendritic cell tumour of tonsil - is it an under-diagnosed entity?

Neoplasms of follicular dendritic cells are uncommon and while majority of them occur in lymph nodes, they are increasingly recognized at varied sites such as abdominal viscera. Tonsil is the most common extra nodal site for occurrence of FDCT in the head and neck region. We describe three cases of follicular dendritic cell tumour occurring in the tonsil.
