    Background: Recent publications have questioned the role of orthotopic liver transplantation (OLT) in treating advanced or unresectable peripheral cholangiocarcinoma (Ch-Ca). Study Design: We reviewed our experience with Ch- Ca to determine survival rates, recurrence patterns, and risk factors in 54 patients who underwent either hepatic resection or OLT between 1981 and 1994. Liver transplantation was performed in patients with unresectable tumors (n = 12) and in those with advanced cirrhosis (n = 8). There were 33 women (61%) and 21 men (39%), with a mean age of 54.3 years. The median followup period was 6.8 years. Prognostic risk factors were analyzed by univariate and multivariate analyses. Results: Mortality within 30 days was 7.4%. Overall patient and tumor-free survival rates were 64% and 57% at 1 year, 34% and 34% at 3 years, and 26% and 27% at 5 years after operation. Thirty-two patients (59.3%) experienced tumor recurrence. Univariate analysis revealed that multiple tumors, bilobar tumor distribution, regional lymph node involvement, presence of metastasis, positive surgical margins, and advanced pTNM stages were significant negative predictors of both tumor-free and patient survival. Multivariate analysis revealed that positive margins, multiple tumors, and lymph node involvement were independently associated with poor prognosis. When patients with these three negative predictors were excluded, the patient survivals at 1, 3, and 5 years were 74%, 64%, and 62%, respectively. Conclusions: Both hepatic resection and OLT are effective therapies for Ch- Ca when the tumor can be removed with adequate margins, the lesion is singular, and lymph nodes are not involved

    PURPOSE: Between September 20, 1995 and September 20, 1996, 120 patients were entered into a prospective, randomized trial comparing tacrolimus and prednisone with (61) and without (59) 2 gm. mycophenolate mofetil daily to determine whether mycophenolate mofetil was associated with a lower incidence of rejection. MATERIALS AND METHODS: Mean recipient age plus or minus standard deviation was 50.8+/-14.1 years (range 18.8 to 84.1). Mean donor age was 34.3+/-21.7 years (range 0.01 to 76). Of the donors 18 (15%) were older than 60 years. Mean cold ischemia time was 30.9+/-8.4 hours (range 14.2 to 49). Median followup was 8.6+/-0.5 months. RESULTS: The 6-month actuarial patient survival was 95%, 92% in the double therapy group and 98% in the triple therapy group (not significant). The 6-month actuarial graft survival was 88%, 84% in the double therapy group and 92% in the triple therapy group (not significant). The overall incidence of rejection and steroid resistant rejection was 34.2 and 4.2%, respectively. There was a strong trend toward less rejection in the mycophenolate mofetil group than in the double therapy group (26.2 versus 42.4%). Crossover was common, and was 42.6% from triple to double therapy and 18.6% from double to triple therapy. The reasons for discontinuation of mycophenolate mofetil were gastrointestinal toxicity, primarily diarrhea, or less commonly hematological toxicity, primarily neutropenia or thrombocytopenia. Gastrointestinal toxicity was ameliorated by separating the doses of tacrolimus and mycophenolate mofetil by 2 to 4 hours, and reducing the dose to 1 gm. daily. CONCLUSIONS: Mycophenolate mofetil appears to be a useful third agent with tacrolimus in patients undergoing renal transplantation, and is associated with a reduction in the rate of rejection and a low incidence of steroid resistant rejection. There is a high incidence of gastrointestinal toxicity associated with the 2 gm. daily dose but this complication is relatively straightforward to manage

    Hepatic Sarcoidosis Mimicking Hilar Cholangiocarcinoma: Case Report and Review of the Literature

    Sarcoidosis is a multisystemic granulomatous disease of unknown etiology. Hepatic involvement was reported in about 11% of patients with sarcoidosis. However, cases of sarcoidosis in which the granuloma is solitary and limited in the liver are very rare. A 51-year-old woman with tumors in the liver underwent extended left lobectomy with caudate lobectomy and bile duct resection. The tumor was located between segment 4 and the hilar region. Some daughter nodules were found in the left lobe, which were regarded as intrahepatic metastasis. Our case displayed clinical and radiologically distinct findings, which are very similar to those of hilar cholangiocarcinoma restricted to the liver. This report demonstrates that sarcoidosis can show solitary hepatic involvement in the absence of thoracic lymphadenopathy. In such a case, it is difficult to distinguish the diagnosis from other malignant neoplasms. In conclusion, the diagnosis of hepatic sarcoidosis has to be made through prudent and comprehensive investigations that include a full clinical history of sarcoidosis in other organs. Despite utilizing several detailed diagnostic modalities, the definitive diagnosis of cases of solitary sarcoidosis may remain difficult. In these cases, surgical treatment including liver resection should be considered in order to avoid missing a suitable opportunity for treatment
