Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Hepatocellular carcinoma is a major histological subtype of liver cancer, and can account for over 90% of primary liver cancer. After the chronic liver disease patient finishes treatment in the hospital, the hospital can acquire the longitudinal follow-up case information with time sequence characteristics of the patient at different time points in a follow-up mode, and timely obtain relevant feedback of the patient condition change. Some patients may have multiple diseases, and the follow-up mode can also help doctors to track and observe information data of other diseases of the patients to a certain extent. Good prognosis of hepatocellular carcinoma depends in large part on early diagnosis and disease stage of hepatocellular carcinoma. The average survival time of early/very early liver cancer patients after surgical excision, ablation surgery and liver transplantation is more than 5 years.
If the monitoring of the hepatocellular carcinoma can be more accurately carried out, the patients with high risk of the hepatocellular carcinoma can be identified early, the method is helpful for guiding clinicians to select and implement more accurate treatment measures for the patients, and the patients can be subjected to intervention and treatment as early as possible, so that better operation effects are obtained, the prognosis of the patients is improved, and the method is one of key measures capable of remarkably improving the survival rate of the hepatocellular carcinoma.
Currently, there are a variety of hepatocellular carcinoma predictive models for hepatocellular carcinoma monitoring clinically, but due to the lack of multi-etiology, multi-clinical feature construction and verification queues, and the current complex clinical trends of more and more chronic liver disease patients with more complications, metabolic disorders, antiviral treatment effects, the application of the hepatocellular carcinoma predictive model is limited and the efficacy of the hepatocellular carcinoma predictive model in the population needs to be further evaluated. Because only single follow-up data is based on baseline clinical data, the traditional COX or Logistic regression model and other hepatocellular carcinoma prediction models ignore the characteristic that the hepatocellular carcinoma risk/recurrence risk is progressed/resolved in the follow-up time, namely the characteristic of continuous change, and the efficacy of the hepatocellular carcinoma prediction model is obviously reduced in the population of patients suffering from chronic liver diseases such as liver cirrhosis. Clinically, the problems of unreasonable monitoring and management of the hepatocellular carcinoma, untimely treatment and management, and communication between doctors and patients are also easy to cause.
The follow-up visit refers to an observation method for a hospital to regularly know the change of the illness state of a patient and guide the rehabilitation of the patient in a communication or other modes for the patient who has been in the visit, the service level before and after the hospital can be improved through the follow-up visit, meanwhile, a doctor can conveniently track and observe the patient, and the first hand data is mastered to carry out statistical analysis and accumulated experience, so that the patient can be better served.
In order to solve the above-mentioned problems, as shown in fig. 1, fig. 1 is a flow chart of a modeling method of a hepatocellular carcinoma monitoring model based on longitudinal multidimensional data provided in the present embodiment. The modeling method of the embodiment of the invention can be used in electronic equipment. As shown in fig. 1, the modeling method includes the steps of:
s10, longitudinal follow-up case information of the sample patient is obtained, the longitudinal follow-up case information is processed, and sample evaluation information of the sample patient is extracted from the longitudinal follow-up case information. The machine direction may characterize the chronological order, i.e. the time sequence. The longitudinal follow-up case information characterizes demographic characteristics, clinical characteristics, laboratory examination indicators, and medical and medication history of the sample patient at various time points of the follow-up process with time series characteristics.
Longitudinal follow-up case information for a sample patient may be obtained by way of follow-up. The longitudinal follow-up case information can be stored in a database of a medical and health system of a hospital, and can also be text information and image information which are fed back by a sample patient independently, and can also be obtained after medical staff records the text information and the image information which are fed back by the sample patient, for example, the relevant information recorded on a case book. The method for acquiring the longitudinal follow-up case information is not limited at all, and only the longitudinal follow-up case information can be acquired.
Since the longitudinal follow-up case information may be unstructured data, in step S10, the unstructured data in the longitudinal follow-up case information is also structured, so that sample evaluation information of the evaluator can be extracted therefrom. It should be noted that not all the structured longitudinal follow-up case information is sample evaluation information, and the sample evaluation information is related data/features for subsequent model modeling, which are obtained after screening from the structured longitudinal follow-up case information.
In the embodiment of the invention, the sample evaluation information of the sample patient is clinical data of the sample patient, including gender, age, liver index information and the like, and the liver index information can be obtained by a medical physical examination mode and the like, and comprises the following information:
Alpha Fetoprotein (AFP), albumin (ALB), total Bilirubin (TBIL), and platelet count (PLT) in sample patients.
S20, determining first sample characteristic information from sample evaluation information of a sample patient, and constructing a first model based on the first sample characteristic information of the sample patient, wherein the first model is used for predicting a first prediction score, and the first prediction score is used for representing a hepatocellular carcinoma monitoring condition corresponding to the sample patient.
In the embodiment of the invention, the first prediction score is obtained based on a first model, wherein the first model adopts an aMAP score model, and the first model is an aMAP (age-Male-ALBI-Platelets) model.
In practical application, the input data of the first model is evaluation information extracted from current follow-up case information generated by follow-up of the to-be-evaluated person, and the evaluation information is used for obtaining a first prediction score of the to-be-evaluated person.
The first sample characteristic information includes part of information in sex, age, and liver index information of the sample patient. More specifically, the aamap model computes a corresponding first predictive score based on the gender, age, albumin, total bilirubin, and platelet count of the sample patient in liver index information, i.e., the first sample characteristic information includes age, gender, albumin, total bilirubin, and platelet count.
That is, the first model contains only three common clinical test indexes, namely Albumin (ALB), total Bilirubin (TBIL) and platelet count (PLT), besides age and gender, so that the risk prediction model and the method based on the risk prediction model can be well popularized in primary hospitals, and the aap score can obtain better evaluation performance in patients in liver inflammation activity period because the index of liver inflammation is not involved.
In an embodiment of the invention, the first model is modeled by:
a10, determining the first sample characteristic information.
The determining process of the first sample characteristic information can be seen in detail in step S20 shown in fig. 1, and will not be described in detail herein.
a20, determining an initial evaluation factor corresponding to the first sample characteristic information.
a30, adjusting the initial evaluation factor to obtain a first evaluation factor.
a40, constructing a first model based on the first sample characteristic information and the first evaluation factor.
The calculation mode of the finally obtained first prediction score is as follows:
aMAP= ({ 0.06×age+0.89×gender (male: 1; female: 0) +0.48× [ (log) 10 TBIL× 0.66) + (ALB × -0.085)] -0.01 ×PLT)} + 7.4)/14.77 × 100
It is understood that 0.06, 0.89, 0.48, 0.66, -0.085, 0.01, 7.4, 14.77 and 100 in the above formula are all the corresponding first evaluation factors of the aap scoring model.
S30, inputting sample evaluation information of the sample patient into the constructed first model to obtain a first prediction score corresponding to the sample patient output by the first model.
Specifically, step S30 includes: sample evaluation information of the sample patient is input into a first model, and the sample evaluation information is processed based on first sample characteristic information and a first evaluation factor corresponding to the first model to obtain a first prediction score output by the first model.
S40, determining second sample characteristic information from the first prediction scores and the sample evaluation information of the sample patients, and constructing a second model based on the second sample characteristic information and the first prediction scores of the sample patients, wherein the second model is used for predicting second prediction scores, and the second prediction scores are also used for representing the hepatocellular carcinoma monitoring conditions corresponding to the sample patients.
In the embodiment of the invention, the second prediction score is obtained based on a second model, and the second model also utilizes an aMAP score model, and the second model is an aMAP-2 model.
In practical application, the input data of the second model is evaluation information and a first prediction score extracted from longitudinal follow-up case information generated by the follow-up of the person to be evaluated at the time of the follow-up and the previous follow-up, and the second model is used for obtaining a second prediction score of the person to be evaluated.
The second sample characteristic information includes part of information in liver index information of the sample patient. More specifically, the aap-2 model calculates a corresponding second predictive score based on the first predictive score of the sample patient, alpha fetoprotein in the liver index information, i.e., the second sample characteristic information includes the first predictive score and alpha fetoprotein.
In an embodiment of the invention, the second model is modeled by the following steps:
b10, grouping the sample patients to obtain a sample patient of a diseased group (hepatocellular carcinoma group patient) and a sample patient of a non-diseased group (non-hepatocellular carcinoma group patient).
b20, fitting sample evaluation information of sample patients in the diseased group and the non-diseased group and a first prediction score generated during the follow-up and the previous follow-up based on an initial longitudinal model to obtain a first group average contour of the diseased group and a second group average contour of the non-diseased group respectively, wherein the initial longitudinal model adopts a multi-element linear mixed effect model (Multivariate Linear Mixed Effect Models, MLMM).

sample patients who have participated in the second model modeling enter a training library, and each time a new sample patient and its sample evaluation information are acquired, the longitudinal profile of the new sample patient is calculated by using the sample evaluation information, and compared with the first group average profile and the second group average profile to give a group prediction probability that the sample patient is classified as a hepatocellular carcinoma group, namely, a second prediction score (aMAP-2 score), which is used for continuing training the second model. The range of values for the second predictive score is 0-1, the closer the second predictive score is to 1, the greater the probability that the sample patient is classified as a group of hepatocellular carcinoma.
In the embodiment of the invention, the grouping prediction probability is obtained based on a marginal prediction method, namely, the aMAP-2 score is obtained based on the marginal prediction method, and a specific calculation formula is as follows:

For each bayesian MCMC simulation, two chains of sufficient length were used (6000 iterations total, the first 3000 iterations burned out) and the convergence between the two MCMC chains was evaluated by the trajectory graph, all bayesian MCMC simulations using no information priors generated by the algorithm.
Dynamic changes in hepatocellular carcinoma risk during patient follow-up are demonstrated by the changed aap-2 score that will be generated for each follow-up, and the average time difference between the time that a hepatocellular carcinoma patient is predicted to be a high risk outcome by an aap-2 score and its clinical diagnosis can be represented by the average prediction period (MLT). MLT results of aMAP-2 scores show that hepatocellular carcinoma patients can be early warned for the first time to be at high risk of hepatocellular carcinoma, so that monitoring of the hepatocellular carcinoma is enhanced in time and intervention is performed in time.
S50, sequentially processing the constructed first model and the constructed second model to construct a third model. The third model is used for predicting a third prediction score, and the third prediction score is also used for representing the corresponding hepatocellular carcinoma monitoring condition of the sample patient.
In the embodiment of the invention, the third prediction score is obtained based on a third model, and the third model is an aamap aMAP-2 model because the third model is obtained based on sequential application of the constructed first model and the second model. Specifically, during actual application of the third model, sequential application of the first model and the second model means that a first prediction score of the to-be-evaluated person is obtained by using the first model, and when the first prediction score corresponding to the first follow-up visit of the to-be-evaluated person exceeds the first score, a second prediction score of the to-be-evaluated person is obtained by using the second model, and a third prediction score of the to-be-evaluated person is obtained according to the previous first prediction score and the second prediction score; and when the first predictive score corresponding to the first follow-up visit of the to-be-evaluated person does not exceed the first score, obtaining a third predictive score directly according to the first predictive score.
Therefore, the third predictive score obtained based on the third model has higher hepatocellular carcinoma monitoring precision and good layering monitoring effect on hepatocellular carcinoma, and can guide doctors to develop better treatment schemes for patients.
According to the modeling method of the hepatocellular carcinoma monitoring model, the sample evaluation information of which the longitudinal data type comprises the serological markers is extracted from the longitudinal follow-up case information of the sample patient, the first model is constructed based on the sample evaluation information, the second model is constructed based on the sample evaluation information and the first prediction score output by the first model, and finally the final third model is obtained based on the first model and the second model by sequential application, so that the method has higher hepatocellular carcinoma monitoring precision and good layering monitoring effect of the hepatocellular carcinoma under the condition of not increasing extra economic burden, and the third prediction score output by the third model can guide doctors to formulate better treatment schemes for patients.

Longitudinal follow-up case information for a sample patient may be obtained by way of follow-up. The longitudinal follow-up case information can be stored in a database of a medical and health system of a hospital, and can also be text information and image information which are fed back by a sample patient independently, and can also be obtained after medical staff records the text information and the image information which are fed back by the sample patient, for example, the relevant information recorded on a case book. The method for acquiring the longitudinal follow-up case information is not limited at all, and only the longitudinal follow-up case information can be acquired.
Since the longitudinal follow-up case information may be unstructured data, the unstructured data in the longitudinal follow-up case information is also structured in the first building module 20, so that sample evaluation information of the evaluator can be extracted therefrom. It should be noted that not all the structured longitudinal follow-up case information is sample evaluation information, and the sample evaluation information is related data/features for subsequent model modeling, which are obtained after screening from the structured longitudinal follow-up case information.
In the embodiment of the invention, the sample evaluation information of the sample patient is clinical data of the sample patient, including gender, age, liver index information and the like, and the liver index information can be obtained by medical physical examination and the like, and the liver index information comprises Alpha Fetoprotein (AFP), albumin (ALB), total Bilirubin (TBIL) and platelet count (PLT) of the sample patient.

The first sample characteristic information includes a portion of information training in gender, age, and liver index information of the sample patient. More specifically, the aamap model computes a corresponding first predictive score based on the gender, age, albumin, total bilirubin, and platelet count of the sample patient in liver index information, i.e., the first sample characteristic information includes gender, age, albumin, total bilirubin, and platelet count.
That is, the first model contains only three common clinical test indexes, namely Albumin (ALB), total Bilirubin (TBIL) and platelet count (PLT), except for age and gender, so that the risk prediction model and the device based on the risk prediction model can be well popularized in primary hospitals, and the aap score can obtain better evaluation performance in patients in liver inflammation activity period because the index of liver inflammation is not involved.
The prediction evaluation module 30 is configured to input sample evaluation information of a sample patient into the constructed first model, and obtain a first prediction score corresponding to the sample patient output by the first model.

The third model is used for predicting a third prediction score, and the third prediction score is also used for representing the corresponding hepatocellular carcinoma monitoring condition of the sample patient.
In the embodiment of the present invention, the third prediction score is obtained based on a third model, and since the third model is obtained based on a constructed first risk prediction model and a constructed second model which are sequentially applied, the third model is an aamap-2 model. Specifically, during actual application of the third model, sequential application of the first model and the second model means that a first prediction score of the to-be-evaluated person is obtained by using the first model, and when the first prediction score corresponding to the first follow-up visit of the to-be-evaluated person exceeds the first score, a second prediction score of the to-be-evaluated person is obtained by using the second model, and a third prediction score of the to-be-evaluated person is obtained according to the previous first prediction score and the second prediction score; and when the first predictive score corresponding to the to-be-evaluated person does not exceed the first score, obtaining a third predictive score directly according to the first predictive score.
Therefore, the third predictive score obtained based on the third model has higher hepatocellular carcinoma monitoring precision and good layering monitoring effect on hepatocellular carcinoma, and can guide doctors to develop better treatment schemes for patients.
