Hepatocellular carcinoma is one of the leading causes of cancer related death in the world. Biannual surveillance for the disease in patients with cirrhosis and in high risk carriers of hepatitis B virus allows early stage cancer detection and treatment with good long term outcomes. Liver ultrasonography and serum α fetoprotein are the most commonly used surveillance tests. If suspicious results are found on the surveillance test, multiphasic computed tomography or magnetic resonance imaging should be undertaken to confirm the diagnosis of hepatocellular carcinoma. If radiologic tests show inconclusive results, liver biopsy or repeat imaging could be considered for confirmation of hepatocellular carcinoma. Management of the disease is complex. Patients should be evaluated by a multidisciplinary team, and the selection of treatment should consider factors such as tumor burden, severity of liver dysfunction, medical comorbidities, local expertise, and preference of patients. Early stage hepatocellular carcinoma is best managed by curative treatment, which includes resection, ablation, or transplantation. Patients with intermediate stage disease often receive locoregional treatment. Systemic treatment is reserved for patients with advanced disease. Several positive, phase III, randomized controlled trials have expanded the systemic treatment options for advanced hepatocellular carcinoma with promising long term outcomes, especially trials using combination treatments, which could also have eventual implications for the treatment of earlier stage disease.

Obesity is increasingly common before and after liver transplantation (LT), yet optimal management remains unclear. Our aim was to analyze the effectiveness of a multidisciplinary protocol for obese patients requiring LT, including a noninvasive pretransplant weight loss program, and a combined LT plus sleeve gastrectomy (SG) for obese patients who failed to lose weight prior to LT. Since 2006, all patients referred LT with a BMI > 35 were enrolled. There were 37 patients who achieved weight loss and underwent LT alone, and 7 who underwent LT combined with SG. In those who received LT alone, weight gain to BMI > 35 was seen in 21/34, post-LT diabetes (DM) in 12/34, steatosis in 7/34, with 3 deaths plus 3 grafts losses. In patients undergoing the combined procedure, there were no deaths or graft losses. One patient developed a leak from the gastric staple line, and one had excess weight loss. No patients developed post-LT DM or steatosis, and all had substantial weight loss (mean BMI = 29). Noninvasive pretransplant weight loss was achieved by a majority, though weight gain post-LT was common. Combined LT plus SG resulted in effective weight loss and was associated with fewer post-LT metabolic complications. Long-term follow-up is needed.

Background. Sixty-five patients with unresectable hilar cholangiocarcinoma (CCA) have undergone orthotopic liver transplantation (OLT) after neoadjuvant chemoradiotherapy per a clinical care protocol developed in 1993. We reviewed our experience with the aim to identify clinicopathological predictors of disease recurrence. Methods. All patients with CCA that underwent OLT at our institution between 1993 and January 1, 2006 were treated in accord with our published protocol. We analyzed multiple clinical and explant pathologic factors using Cox regression analysis. Results. Sixty-five patients with CCA underwent OLT. Four patients died within six months due to postoperative complications. At last follow-up, 11 patients (17%) had developed recurrence seven to 64 months after OLT. Mean time to recurrence was 29 months, and eight patients had died from recurrent disease. Patient and disease-free survival were 76% and 60% five years after OLT. Predictors of recurrence were older age, pretransplant cancer antigen (CA) 19-9 >100 U/ml, prior cholecystectomy, mass on cross-sectional imaging, residual tumor in explant >2 cm, tumor grade and perineural invasion in explant. Underlying primary sclerosing cholangitis, percutaneous biliary intubation, gender, and other time points for CA 19-9 were not associated with recurrence. Prolonged staging-to-OLT intervals for patients transplanted after implementation of model for end-stage liver disease (MELD) showed a trend toward increased recurrence. Conclusions. Older patients and those with high CA-19.9 levels, and larger tumors are more likely to develop recurrent disease. Prolonged waiting time may emerge as a significant risk factor with longer follow-up. These findings may guide patient selection, applicability of live donor transplantation and MELD score exceptions for this aggressive protocol.
