The most accepted hypothesis describes a step-by-step process through which external stimuli induce genetic alterations in mature hepatocytes leading to cell death and cellular proliferation regeneration.
The rest of stage A patients were treated initially: Staging systems are key to predict the prognosis of patients with cancer, to stratify the patients according to prognostic variables in the setting of clinical trials, to allow the exchange of information among researchers, and finally to guide the therapeutic approach.
In Spain an important proportion of patients at risk of HCC are not in a surveillance program 11which is due to a lack of strict compliance with the same, as well as not knowing of the existence of underlying liver cirrhosis in those patients with asymptomatic live disease.
Patients at stage C with advanced HCC may receive new agents in the setting of RCT, and patients at stage D with end-stage hepatocwrcinoma will receive symptomatic treatment. Survival was defined as the time elapsed from the date of diagnosis and either the date of death or the date of last follow-up information.

In oncology, the prognosis of patients with solid tumors is solely related to tumor stage, and other co-factors such as age or histologic grade are only seldom considered. Some studies found that HCC patients with high AFP tended to have greater tumor size, bilobar involvement, massive or diffuse types, and portal vein thrombosis, and dd, AFP was a prognostic indicator This process may last 10—30 years Based on the results of a series of patients who underwent resection 29a recent modification has been proposed, including tumor stage and presence of fibrosis.
This classification uses hepatocwrcinoma related to tumor stage, liver functional status, physical status, and cancer-related symptoms, and links the four stages described barcelkna a treatment algorithm Figure 1.
A new prognostic classification for predicting survival in patients with hepatocellular carcinoma.
The main advantage of the BCLC staging system is that it links staging with treatment modalities and with an estimation of life expectancy that is based on published response rates to the different treatments Afiatoxin B 1 intake further enhances the risk. Increased survival of cirrhotic patients with a hepatocellular carcinoma detected during surveillance.
Staging systems in hepatocellular carcinoma
Thus, molecular markers are needed in HCC. The new four-stage system may improve the stratification of resected tumors, even though it is controversial whether they will apply to nonsurgical patients. The natural history of this neoplasm is not completely known. Others studies also found a biologic role of AFP 39, Trends in mortality from hepatocellular carcinoma in Europe, Hepatocellular carcinoma in Central Europe: Natural history of untreated nonsurgical hepatocellular carcinoma: A patient was excluded from the analyses because AFP was clasifjcacion available at diagnosis.
Management of hepatocellular carcinoma: The value of alpha-fetoprotein AFP has not been properly defined. Only patients managed by specialized practitioners in HCC from our department were included. In this way, in the last years there were improvements in the different prognostic scores. Patients at stage B with intermediate HCC may benefit from chemoembolization.
No patients were remitted to other hospitals, batcelona those to be evaluated for LT liver transplant. According the BCLC system the survival varies from one study to another. Investigators have developed gene expression-based classifications for breast cancer, non-Hodgkin’s B-cell lymphoma, leukemia, lung carcinoma, prostate cancer, bladder cancer, and melanoma.
Three patients with a single nodule greater than 8 cm were classified as stage B because we considered that they had a multinodular tumor. A total of 86 patients Even some societies have endorsed one of the systems 42with controversial acceptance 43 These figures have also been recently reproduced when analysing survival estimates gathered from population-based cancer barcwlona The following variables were recorded for each patient: A clasificcion of survival rates of untreated patients in randomized clinical trials of hepatocellular carcinoma.
Natural history of compensated viral cirrhosis: The patients were studied and managed according to usual clinical practice. Very early 11 A: Introduction Hepatocellular carcinoma HCC is a major health problem worldwide. AFP elevation, more than a coincidental epiphenomenon, appears to contribute to vascular invasion and HCC progression and help to identify subsets of HCC patients with increased risk for early recurrence and poor prognosis after hepatectomy And some studies included special patients, for example only asymptomatic patients with non-surgical treatment.
Staging systems in hepatocellular carcinoma
PEI was performed under ultrasound guidance. The decision for therapy was made by the specialist practitioner and in special cases made by a multidisciplinary team consisting of hepatologists, oncologists, radiologists and surgeons. Treatment approach of hepatocellular carcinoma in Spain. Discussion Over the past few years, the wide spread use and development of more sophisticated diagnostic tools, and the improvement of therapeutic techniques, although not “radical”, have allowed a higher number of HCC patients to be treated and have led to an improvement in overall survival.
Similarly, advanced tumors in Child-Pugh C patients also account for a very poor prognosis. Support Center Support Center. Univariate survival curves were estimated using the Kaplan-Meier method; the differences in the survival rates between the groups were compared using the log-rank test. Finally, the potential relevance of a molecular signature identified in terms of outcome prediction is unknown, and further research is needed to obtain this valuable biological information that may aid in classifying the patients.
Aliment Pharmacol Ther ; Hepatocellular carcinoma HCC is the most common primary liver malignancy 1 and is the major cause of deaths in patients with cirrhosis hepaocarcinoma.
