Liver cancer early the liver cancer estimate system and its control method for diagnosing (LIVERCANCERPREDICTIONSYSTEMFOREARLYDETECTIONANDCONTROLMETHODTHEREOF)

摘要

The present invention relates to a liver cancer prediction system for early detection and control method thereof, which can perform hierarchical classification relating to a risk group for hepatocellular carcinoma, through an estimation of the incidence rate for the hepatocellular carcinoma and a relative risk of the incidence of hepatocellular carcinoma, both of which are found on an individual basis. General information on a patient, information depending on an ultrasonic test performed, clinical information including information on findings upon a first registration of a patient and information on findings upon a diagnosis of liver cancer, and information on a risk group, are stored in a database. A regression count which is an attributable ratio corresponding to each of risk factors is calculated based on the clinical information and risk group information stored in the database. An odds ratio of the incidence of liver cancer is measured by calculating risk probability of the incidence of liver cancer through a given operation process using the calculated regression count. It is thus possible to prevent the incidence of liver cancer per person depending on prediction of the incidence of liver cancer. Also hierarchical classification relating to a risk group for hepatocellular carcinomas is performed through the incidence rate for hepatocellular carcinoma and a relative risk of the incidence of liver cancer that are calculated on an individual basis. Therefore, a tailored model for prediction the incidence of liver cancer can be constructed.
