To see whether or not there is an association between the cause of cirrhosis and the number of hepatocellular carcinoma (HCC) nodules, we analyzed 178 consecutive patients in whom HCC was detected during a prospective screening by abdominal ultrasound (US). The relevant information was obtained from the database of the screening programs operating at four hospitals in the Milan area. One hundred twenty-nine (72%) patients had a single tumor nodule detected by US and 49 (28%) patients had multinodular disease. Ninety-eight (55%) patients had normal serum values of ␣-fetoprotein (AFP). Tumor staging with biphasic computed tomography (CT) scan or hepatic arteriography with lipiodol revealed that 101 (57%) patients had single tumor nodules and 77 (43%) patients had more than one HCC nodule. After staging, multinodular HCC was more common in patients with multiple risk factors than in the hepatitis C virus (HCV) carriers (56% vs. 38%, P ؍ .05). Interestingly, single tumors were as common in the 126 patients undergoing 6-month interval screening as in the 52 patients who were studied at yearly intervals. The former patients, however, had more small tumors than the latter ones (91% vs. 74%, P ϭ .04). The 22 patients who were alcohol abusers had normal levels of serum AFP more often than the hepatitis B virus (HBV) or HCV carriers or those with multiple risk factors (86% vs. 57%, P F .04; vs. 47%, P F .002; vs. 52%, P F .006, respectively). We concluded that multinodular HCC was underdetected by real time US; it prevailed among patients with multiple risk factors. In these patients, screening with US exams every 6 months may be inadequate for early detection of liver cancer. (HEPATOLOGY 1999;29:1704-1707

Aims: Hepatocellular carcinoma (HCC) represents O90% of primary liver neoplasms and develops mainly in patients with liver cirrhosis. Risk factor identification for the development of HCC in patients with cirrhosis possesses great clinical relevance due to its high incidence and poor prognosis when detected at advanced stages. The aim of this study was to identify HCC development-associated risk factors in a cohort of patients with hepatitis virus-related chronic liver disease and cirrhosis. Materials and methods: Patients with a diagnosis of hepatitis virus-related cirrhosis between January 1980 and January 2000 were included. Patients were followed with an abdominal ultrasound and the determination of alpha-fetoprotein levels, a physical examination, and routine biochemical tests every 3e6 months. The end point of the study was defined as the development of HCC. Liver histology was evaluated according to the French METAVIR Cooperative Study Group (METAVIR) score. Results: Two hundred and eighty-two patients met the inclusion criteria; most of these (86%) had a serologic diagnosis of hepatitis C virus, and only 14% had hepatitis B virus at the time of the diagnosis of cirrhosis, whereas 56 and 37% were classified as Child A and B, respectively, and only 7% as Child C. Histological activity was mild in 59% of patients, and moderate and severe in 41%. The mean annual incidence was 1.87%, and 22 and 35% of patients developed HCC at 10 and 15 years of follow-up, respectively. The diagnosis of HCC was made by histopathology in 37% and by tumoural lesionassociated alpha-fetoprotein elevation confirmed by imaging studies in 63%. In multivariate analysis, we found three variables associated with HCC: moderate to severe histological activity; a platelet count !105 3 10 3 /mm 3 , and alphafetoprotein O5 ng/ml. The patients were divided into two groups according to regression coefficient: low and high risk; patients assigned to the low-risk group showed 5-, 10-and 15-year HCC incidences of 3.4, 6.4 and 6.4%, respectively, in contrast to patients from the high-risk group, who showed incidences of 17.8, 33.5 and 56.8%, respectively. Conclusions: We found three HCC-associated variables: histological activity, platelet count and alpha-fetoprotein levels. Patients considered as high risk for developing HCC must be considered candidates for closer follow-up. Rodríguez-Díaz,
Hepatocellular Carcinoma: Risk Factors, Diagnosis, Staging and Treatment in a Referral Centre
Journal of Cancer Therapy, 2013
Introduction: Hepatocellular carcinoma is the most common primary neoplasm of the liver and a significant cause of mortality in patients with cirrhosis. A retrospective cross-sectional study was performed to analyze epidemiological aspects related to risk factors, diagnosis, staging and first-line treatment in a closed population. Methods: The medical records of patients seen between November 1998 and May 2011 were revisited. Results: Of the 272 patients included in this study, 229 (84.2%) were male and the average age was 57.1 years (standard deviation 10.9 years). The most common etiology was hepatitis C virus infection in 145 (55.1%) patients, with this being the single cause in 88 (33.4%) patients. The largest masses ranged from 6 mm to 260 mm in diameter with a mean of 61.4 mm (standard deviation 41.5 mm). Only one mass was found in 145 (64.2%) cases, two masses in 26 (11.5%), three masses in 9 (4%) and 46 patients (20.3%) had multifocal disease. Early stage disease was diagnosed in 47 patients (22.0%), advanced stage in 65 (30.4%) and terminal stage in 32 (14.9%). Hepatocellular carcinoma was found by chance in 11%. Diagnosis was by means of imaging in 175 (68.1%) cases. The level of alpha-fetoprotein was measured in 209 patients, with 29.2% having levels lower than 20 ng/mL and 34.9% having levels above 400 ng/mL. Specific treatment was administered in 236 patients (86.8%) with hepatic chemoembolization in 127 (46.7%) and liver transplantation in 72 (26.5%); of these 33 (45.8%) received hepatic chemoembolization as a bridge to transplantation. Thirty-four patients (12.5%) received only supportive therapy. Conclusions: Patients are chiefly male and disease involvement generally occurs in the 5th decade of life. Cirrhosis was present in most patients and hepatitis C virus infection was the commonest etiologic agent. Only one imaging examination was required for diagnosis in most patients. The measurement of alpha-fetoprotein levels did not prove to be a good tool in the diagnosis of hepatocellular carcinoma. Intermediate, advanced and terminal stages predominated compared to early stages. Treatment was based on non-curative therapies.

AIM: To compare the clinical outcome and pathologic features of non-alcoholic steatohepatitis (NASH) patients with hepatocellular carcinoma (HCC) and hepatitic C virus (HCV) patients with HCC (another group in which HCC is commonly seen) undergoing liver transplantation. METHODS: Patients transplanted for HCV and NASH at our institution from January 2000 to April 2011 were analyzed. All explanted liver histology and pre-transplant liver biopsies were examined by two specialist liver histopathologists. Patient demographics, disease free survival, explant liver characteristics and HCC features (tumour number, cumulative tumour size, vascular invasion and differentiation) were compared between HCV and NASH liver transplant recipients. RESULTS: A total of 102 patients with NASH and 283 patients with HCV were transplanted. The incidence of HCC in NASH transplant recipients was 16.7% (17/102). The incidence of HCC in HCV transplant recipients was 22.6% (64/283). Patients with NASH-HCC were statistically older than HCV-HCC patients (P < 0.001). A significantly higher proportion of HCV-HCC patients had vascular invasion (23.4% vs 6.4%, P = 0.002) and poorly differentiated HCC (4.7% vs 0%, P < 0.001) compared to the NASH-HCC group. A trend of poorer recurrence free survival at 5 years was seen in HCV-HCC patients compared to NASH-HCC who underwent a Liver transplantation (P = 0.11). CONCLUSION: Patients transplanted for NASH-HCC appear to have less aggressive tumour features compared to those with HCV-HCC, which likely in part accounts for their improved recurrence free survival.

More than one and half of current cases of hepatocellular carcinoma in the US, Europe, and Japan are attributable to hepatitis C virus (HCV) infection. HCV is also the primary cause of death in patients with HCV-related cirrhosis, with annual incidences of 0.5%-5% in Europe and 4%-10% in Asia. Screening is based on serum alpha-fetoprotein determination and liver ultrasound scan, but the sensitivity of the former is far less than optimal, and screening intervals are still poorly defined for the latter. Risk factors related to the host or environment, or both, appear to be more relevant than viral factors, such as HCV genotype, in determining disease progression to cirrhosis and cancer, and include age, male gender, severity of liver disease at presentation, coinfection with hepatitis B virus or human immunodeficiency virus, and alcohol abuse. Early liver transplantation in selected cases can be curative, but most patients are not eligible for liver grafting and are treated with locoregional ablative therapies, after which recurrence is common. Recently, orally available inhibitors of the vascular endothelial growth factor receptor have shown a significant, albeit modest, increment of survival in patients with advanced hepatocellular carcinoma, thus paving the way for modern molecular approaches to treatment of this highly malignant tumor.

The efficacy of orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC) associated with hepatitis C virus (HCV) is not well defined. This study examines the variables that may determine the outcome of OLT for HCC in HCV patients. From 1990 to 1999, 463 OLTs were performed for HCV cirrhosis. Of these patients, 67 with concurrent HCC were included in the study. Univariate and multivariate analyses considered the following variables: gender, pTNM stage, tumor size, number of nodules, vascular invasion, incidental tumors, adjuvant chemotherapy, preoperative chemoembolization, alphafetoprotein (AFP) tumor marker, lobar distribution, and histological grade. Overall OLT survival of HCV patients diagnosed with concomitant HCC was significantly lower when compared to patients who underwent OLT for HCV alone at 1, 3, and 5 years (75%, 71%, and 55% versus 84%, 76%, and 75%, respectively; P < 0.01). Overall survival of patients with stage I HCC was significantly better than patients with stage II, III, or IV (P < .05).
Hepatitis C and hepatocellular carcinoma
Current Treatment Options in Oncology, 2001
Chronic hepatitis C infection (HCV) accounts for approximately 50% of the cases of hepatocellular carcinoma (HCC) in the United States. Cirrhosis or an advanced stage of fibrosis is the major risk factor of HCC; patients with cirrhosis are recommended to undergo surveillance with alpha-fetoprotein and ultrasound. Alpha interferon (IFN-α) is associated with a reduced risk of HCC in patients with chronic infection but insufficient data exist to recommend treatment of patients with cirrhosis and HCV for this reason alone. Resection and liver transplantation are the only ”curative” therapies available. Advanced fibrosis or cirrhosis in patients with HCC limits the number of patients for whom resection is applicable. Moreover, the remaining liver is at high risk of developing a second primary tumor. Partial hepatic resection for hepatocellular carcinoma should be restricted to patients with well-compensated cirrhosis (Child’s A class). Acceptable parameters include a single lesion not exceeding 5 cm, normal levels of bilirubin, and absence of portal hypertension. Liver transplantation is the best definitive treatment for HCV-infected patients who have small, localized HCC (solitary lesion not greater than 5 cm, or no more than 3 lesions, none of which are greater than 3 cm). Limitations of liver transplantation as a therapy for HCC are the scarcity of donor organs and the prolonged waiting time during which continued tumor growth occurs. Living donors can reduce waiting time and increase the number of patients treatable by transplantation. Chemoembolization and local ablation therapies have not been shown to confer survival benefits as primary treatments for HCC. The potential benefit of these procedures in controlling tumor growth to “bridge” patients to liver transplantation must be further investigated. Similarly, systemic chemotherapy and hormonal therapy do not generally produce a survival advantage. However, recent studies that used octreotide and combination doxorubicin/cisplatin/ 5-FU/interferon appear to be promising.
