In other words, the higher the threshold, the lower the number of detected cases obtained sensitivity decreases.

Influence of tumor characteristics on alfafetoproteina marcador tumoral outcome of liver transplantation among patients with liver cirrhosis and hepatocellular carcinoma. A tumor marker with a high sensitivity would be the one that is elevated in the majority of patients who present certain neoplasm, whereas specificity would be determined by those patients with normal levels of the tumor marker who do not present any type of neoplasm.

Role of tumor markers in patients with solid tumors: Se pueden realizar dos mediciones: The principal causes of HCC, ordered by frequency, were the presence of viral HC HCV-related mainlythe presence of cryptogenic cirrhosis, and the consumption of alcohol.

Analysis of patients. Viral infections, mainly by HCV, and alcohol consumption, were the first and second most important etiologies for HC, respectively.

We can say that, in general, due to the lack of high diagnostic sensitivity and specificity, tumor markers are not helpful for an early detection of neoplasms, but they do help to confirm a diagnosis already established by more sensitive methods. According to the available statistical data, it is the main cause of death in people with compensated hepatic cirrhosis HCand variously alternates between the fifth and alfafetoproteinq position, according to the country, as the most frequent neoplasia to new cases worldwide per year.

Using a diagnostic threshold of Predicting survival after liver transplantation in patients with hepatocellular carcinoma beyond the Milan criteria: The etiology of HC, on the other hand, is better known. Liver transplantation for the treatment of small hepatocellular carcinomas in patients with cirrhosis.

Sin embargo, a pesar de esta lejana referencia, la historia de los MT arranca fundamentalmente en la segunda mitad del siglo XX; hay que tener en cuenta que diversas sustancias que posteriormente se utilizaron como MT han sido descubiertas hace relativamente poco tiempo: The predictive ability of serum a-fetoprotein for hepatocellular carcinoma is linked with the characteristics of the target population at marcado.
