Referrals for surgical therapy in patients with hepatocellular carcinoma: a community experience.
The treatment of hepatocellular carcinoma (HCC) is notoriously difficult. Either because of oncogenic behavior or the frequent association of cirrhosis, successful therapy is elusive, particularly in cirrhotic patients. Surgical removal has been the only modality that has produced long-term, disease-free survival. In a large series of patients from specialty institutions, median survival in those who underwent resection of HCC lesions has ranged from 30 to 70 months. Similarly, liver transplantation has been shown to be an effective treatment when HCC is favorable (limited in size and number), producing long-term survival in greater than 70% of patients. However, less information is known about community-based treatment of HCC. Reports from referral centers may not accurately reflect the community experience. We have retrospectively reviewed patients with HCC seen in surgical referral from three teaching hospitals in a medium-size urban community from 1995 to 2004 who were not felt to be candidates for liver transplantation and who were not sent to referral centers. We sought to examine their suitability for operation and resection. The study group comprised 61 patients, whose ages ranged from 35 to 83 years old. There were 44 patients (72%) with cirrhosis (Childs A, B, and C in 27, 15, and 2 patients, respectively), 21 from hepatitic C virus (HCV) infection. Three recognized staging systems were used that incorporated the estimation of hepatic reserve and tumor burden. Seven patients (11%) were deemed nonoperable (five advanced disease by imaging, two comorbidities). Of the 54 patients who underwent surgical procedures, 32 underwent resection (28 patients) or cryoablation (4 patients). The reasons for unresectability were unrecognized multifocality (ten patients), poor risk for major hepatectomy (five patients), portal vein/hepatic vein involvement (three patients), metastatic disease (two patients), and excessive blood loss prior to hepatectomy (two patients). Eleven of 17 (65%) noncirrhotic patients and 21 of 44 (48%) cirrhotic patients were resectable or ablatable. There were ten postoperative deaths: six following resection, two following cryoablation, and two following exploratory celiotomy. All deaths were in cirrhotic patients (Childs A in four patients, B in five patients, and C in one patient), 10 of 44 patients (23%); 3 of 11 (27%) patients died following segmentectomy and 3 of 9 (33%) following major hepatectomy. Seven deaths that occurred were in patients with HCV; (P = NS). From this series, the difficulty in surgically treating cirrhotic patients in an urban practice is evident. From 39 to 73% of patients had advanced local disease. Less than half were resectable and, for cirrhotic patients, the postoperative mortality was high, even after "minor" hepatectomies. Noncirrhotic patients fared somewhat better. While HCC in community practice can be treated surgically in the majority of noncirrhotic patients, cirrhotic patients are less likely candidates, and surgical treatment is associated with significant postoperative mortality. This frequently reflected advanced disease and HCV but may be associated with access to preventative and surveillance measures. Only those with optimum hepatic reserve and small tumor burden should be considered for surgical resection.
