Preoperative serum alpha-fetoprotein levels can have predictive value for hepatocellular carcinoma survival. Influence of tumor characteristics on the outcome of liver transplantation seria patients with liver cirrhosis and hepatocellular carcinoma.

Results Of the 19 patients evaluated, One patient died due to postoperative liver failure and another from a cerebrovascular event. Twelve of those patients received no treatment, eerica underwent radiofrequency ablation, 2 had transarterial chemoembolization, and 5 received chemotherapy sorafeniball of whom were excluded from the analysis.

Form Med Contin Aten Prim. A receiver operating characteristic ROC curve was plotted to determine the area under the curve, cut-off point, and sensitivity and specificity of preoperative AFP levels for survival in all the patients, calculated using the Kaplan-Meier estimator. 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.



Thus, markers with high levels of sensitivity and specificity would allow for the detection of patients with cancer, and for their differentiation from healthy individuals or from patients with benign pathologies. The clinical value of tumour markers in the management of ovarian cancer.
