Introduction: In the majority of patients transplanted for unresectable liver metastases, long-term results are disappointing because of early tumor recurrence. Due to its biologically less aggressive nature, neuroendocrine metastases (NM) may represent a good indication for liver transplantation (LT)., Patients and Methods: Between January 1996 and May 2000, five patients with NM were transplanted. The primary tumors were located in the pancreas (n=4) and the small bowel (n=1). In three cases there were symptoms related to hormone production: two carcinoids, and one gastrinoma. The management of primary tumors was sequential in three patients with the tumor being resected before LT (one Whipple procedure and two left pancreatectomies). In two patients the resections of the primary tumors and the LT were simultaneous namely one bowel resection and one left pancreatectomy. All patients were treated with chemotherapy., Results: Two patients developed recurrent disease succumbing at 15 months (nonfunctioning NE pancreatic head tumor) and 17 months (carcinoid of the pancreatic tail) post-LT. Another patient died at 3 months post-LT due to technical complications. The other two patients are alive and free of recurrence., Conclusion: Despite the promising results obtained with LT for NM, our experience indicates that patients must be carefully selected. Perhaps the use of more aggressive chemotherapeutic protocols combined with an individualized approach will improve the results.

Introduction: Due to the scarcity of donors and the fact that size is the main prognostic factor, Milan criteria have been used since 1996 to select hepatocellular carcinoma (HCC) patients for liver transplantation. In 2001 UCSF criteria showed that including layer tumors did not reduce the survival results. The objective of this paper was to evaluate whether HCC tumor sizes exceeding the Milan criteria adversely influence survival rates., Patients and Methods: Between May 1988 and July 2001, 53 patients were transplanted due to HCC and cirrhosis. The etiology of cirrhosis was HCV in 23 cases and HBV in 6. In 11 cases the HCC were incidental by discovered namely, a mean/ diameter of 1.8 cm (versus 2.6 cm in nonincidental HCC). Sixty-two percent of tumors met the Milan criteria, and 68% the USCF criteria., Results: The actuarial survival was 79% at 1 year and 62% at 5 years. The survival of patients with incidental HCC was 82% at 1 year and 82% at 5 years, which is better than the survival of those with nonincidental HCC (78% at 1 year and 57% at 5 years, P<.05). According to Milan criteria, the survival patients with early tumors was 82% at 1 year and 68% at 5 years, and for advanced tumors (NS), 75% and 54%, respectively. Comparison of early versus advanced tumors according to UCSF criteria showed survivals of 84% versus 64% at 1 year (P<.05) and 67% versus 48% at 5 years (P<.05), respectively., Conclusion: Increasing the HCC size among LT according to the California criteria did not reduce survival rates compared with the Milan criteria.
