Abstract

Objective A kidney transplant is a suitable surgical management for end-stage renal disease patients; however, posttransplantation malignancy is an unwanted outcome. In Taiwan, hepatocellular carcinoma (HCC) is a major malignancy not only among the general population but also in the post-kidney transplant group. Therefore, regular imaging studies for posttransplantation follow-up are necessary. We examined the imaging characteristics and the efficacy of radiologic diagnostic criteria and the American Joint Committee on Cancer (AJCC) staging system in post-kidney transplantation HCC. Patients and Methods We retrospectively reviewed 15 patients with post-transplantation HCC among 554 hospital-based kidney transplant recipients. From 1988 to 2008 we analyzed the patient profiles, imaging studies, histopathologic diagnosis, treatment methods, and outcomes. The 6th-edition AJCC radiologic staging system was applied for validation in this study. Results Using the AJCC staging system, all 15 patients with histopathologically confirmed HCC were enrolled as stage I (n = 7), stage II (n = 2), stage IIIA (n = 5), or stage IV (n = 1) cases. The 5-year survival rates were 71.4% in stage I, 50% in stage II, 20% in stage IIIA, and 0% in stage IV. Over one-half of post-kidney transplantation HCC were sized 2.5-6.0 cm in diameter with mixed echogenicity. The positive diagnostic rate for radiologic criteria was 83.3%. Conclusions The AJCC staging system and the radiologic diagnostic criteria were validated in post-kidney transplantation HCC. Surgical resection and transcatheter arterial embolization for early-stage HCC in kidney transplant recipients showed satisfactory outcomes. A noncirrhotic liver in a kidney transplant recipient makes surgical resection the treatment of choice because of the better prognosis.
