Hepatitis B vs. hepatitis C infection on viral hepatitis-associated hepatocellular carcinoma.

BACKGROUND: To determine clinical-pathologic variables in patients with a new diagnosis of hepatocellular carcinoma (HCC) and underlying hepatitis B vs. C infection. METHODS: Patients presenting to a single urban hospital with a new diagnosis of HCC were entered into a clinical database. Variables including number and size of tumors, presence of metastases, serum alpha-Fetoprotein, hepatitis serologies, severity of hepatic dysfunction, and presence of cirrhosis were evaluated in 127 patients. RESULTS: Patients with hepatitis B (HBV) were more likely to develop HCC at a younger age than patients with hepatitis C (HCV) (HBV-26% under age 40, HCV-0% under age 40; p < 0.001), with greater serum alpha-Fetoprotein production (median level: HBV-1000 ng/ml vs. HCV-37 ng/ml; p = 0.002), with larger tumors (HBV-78% >5 cm, HCV-28% >5 cm; p < 0.001), in the absence of cirrhosis (HBV-40%, HCV-0%; p < 0.001), and a decreased eligibility for curative treatment (HBV-14%, HCV-34%; p < 0.05). Conversely, patients with HCV were more likely to develop HCC in association with multiple co-morbidities, cirrhosis, and older age. CONCLUSIONS: Significant clinical-pathologic differences exist among HCC patients with underlying HBV vs. HCV. These differences impact eligibility for potentially-curative therapy and prognosis.

Diagnostic laparoscopy in the evaluation of the viral hepatitis patient with potentially resectable hepatocellular carcinoma.

BACKGROUND: Despite significant recent improvements in liver imaging, preoperative evaluation of the potentially resectable patient with viral Hepatitis and Hepatocellular Carcinoma (HCC) is often inaccurate. Diagnostic laparoscopy may change management for patients with under-appreciated nodular cirrhosis or intrahepatic metastases, preventing unnecessary open exploration. The purpose of this study is to determine the effectiveness of routine laparoscopy as a separate procedure prior to resection in the evaluation of patients with potentially resectable HCC. METHODS: Patients with potentially resectable HCC were evaluated preoperatively with routine blood tests and axial imaging. All study patients also underwent diagnostic laparoscopy with laparoscopic ultrasonography. Laparoscopy was performed in an inpatient hospital setting, with 23 hour stays in most cases. RESULTS: Among 65 patients evaluated with Hepatocellular Carcinoma between July 2001 and November 2003, 20 patients with potentially resectable disease were evaluated by diagnostic laparoscopy. All patients had viral Hepatitis: 16 with Hepatitis B and 4 with Hepatitis C. All study patients had cirrhosis; 18 classified as Child's-Pugh A and 2 as Child's-Pugh B. Diagnostic laparoscopy changed the management in 9/20 (45%) cases. Management was changed because of severe nodular cirrhosis in 4 cases, inaccurate assessment of intrahepatic metastases in 2 cases, inability to identify an HCC in 1 case, peritoneal carcinomatosis in 1 case, and inability to tolerate induction to general anesthesia in 1 case. DISCUSSION: Diagnostic laparoscopy is useful in the evaluation of the potentially resectable patient with HCC. Information obtained from laparoscopy may change the clinical management in up to 45% of cases.
