Embodiment 1

[0091] Example 1 The study included patients with baseline characteristics and survival analysis

[0092] Retrospective consecutive incorporated in January 2008 to December 2016 to Capital Medical University, Beijing Ditan Hospital first diagnosed 2890 cases of patients with hepatitis B associated primary liver cancer. In this study, the Ditan hospital ethics committee approval.

[0093] Inclusion criteria: (1) patients diagnosed with primary liver cancer; (2) the age of 18-75 years old; (3) hepatitis B surface antigen positive> 6 months. Excluded: (1) patients with cholangiocarcinoma (n = 196); a patient (4) of the lost (n; (2) patients with metastatic liver cancer (n = 85); (3) combined with other types of tumors (n = 59) = 139); (5) associated with other patients with chronic liver disease (n = 172); (6) clinical data were incomplete (n = 122). The final included 2117 cases of patients. Asia-Pacific liver cancer diagnostic criteria in line with standard clinical guidelines for l...

Embodiment 2

[0101] Example 2 Construction of progression-free survival in patients with hepatocellular carcinoma independent risk factor screening and ANN model

[0102] Literature review and summarize the clinical experiences, identify factors associated with survival of patients with liver cancer include: tumor characteristics, focused on the size of the tumor, invasion, metastasis vessels, satellite nodules; liver function include: albumin, total bilirubin, glutamyl peptidase (r-GGT) and the like. But these indicators with little regard to immune function and inflammatory markers in patients with liver cancer death. Therefore, in this study, a comprehensive collection of clinical data, including:

[0103] (1) demographic characteristics: age, sex, smoking history, drinking history, family history of liver cancer;

[0104] (2) The combined history: diabetes mellitus, hypertension, coronary heart disease, hyperlipidemia, cirrhosis of the liver;

[0105] (3) HBV-related features: HBeAg, HBV-...

Embodiment 3

[0133] Example 3 Comparative discrimination ANN model, the calibration of the model and other

[0134] ANN model constructed using Example 2 1-year progression-free patient training and validation sets to predict survival.

[0135] As a result, in the training concentration, ANN predicted that the underlying PFS probability of PFS probability (AUC) was 0.866 (95% CI 0.848-0.884); C-index was 0.782 (95% Ci 0.767-0.797). In validation concentration, ANN predicts that the underlying PFS of PFS in patients with liver cancer is 0.730 (95% CI 0.690-0.770); the C-index is 0.704 (95% CI 0.675-0.732) (Table 3).

Abstract

The invention provides a device for judging prognosis conditions of liver cancer patients based on an artificial neural network model. The device comprises: (1) an input module configured to input tumor feature information of a to-be-discriminated liver cancer patient; (2) a prognosis discrimination module which is set to comprise an artificial neural network model used for calculating the prognosis condition of the to-be-discriminated liver cancer patient based on the input information; and (3) an output module, wherein the output module is set to output the obtained prognosis condition. Theinvention also provides a method for grouping prognosis conditions of liver cancer patients by adopting the device.

Description

Technical field [0001] The present invention relates to the field of medical, and Background technique [0002] Statistics show that the death caused by liver cancer in the globe accounted for the fourth place in all tumors. Despite the discovery of multiple early monitoring indicators and regular imaging inspections, liver cancer can be diagnosed early, and the treatment level of liver cancer is gradually improved, but due to population growth and aging, the number of liver cancer caused by 2016, the number of people lived in all tumors The third growth in 2006 has grown to the second, and there is research forecast to 2040, the number will continue to rise, more than 69.6%. China's new and death cases account for more than 50% of the world, most of which are caused by HBV infection. [0003] A variety of treatment methods have been seen for liver cancer for different periods, but the recurrence and metastasis of patients after treatment remains the severe problem facing clinica...
