Description

Technical Field

[0001] The present invention belongs to the technical field of hematopoietic stem cell transplantation, and in particular relates to a CART-based personalized hematopoietic stem cell transplantation preprocessing information data method and system. Background Art

[0002] Hematopoietic stem cell transplantation is the process of transplanting healthy hematopoietic stem cells into the patient's body in a specific way to help the patient rebuild a normal blood system. These stem cells have extremely strong self-renewal and multiple differentiation potentials, and can differentiate into a variety of blood cells, including red blood cells, white blood cells and platelets. Hematopoietic stem cell transplantation can be classified in different ways. According to the source, it can be divided into autologous hematopoietic stem cell transplantation and allogeneic (also known as allogeneic) hematopoietic stem cell transplantation. Allogeneic hematopoietic stem cell transplantation can be divided into blood-related donor hematopoietic stem cell transplantation and unrelated donor hematopoietic stem cell transplantation (i.e., unrelated transplantation) according to whether the donor has a blood relationship with the patient. In addition, it is divided into peripheral blood hematopoietic stem cell transplantation, bone marrow transplantation and umbilical cord blood hematopoietic stem cell transplantation according to the type of transplant. The current hematopoietic stem cell transplantation pretreatment regimen is not personalized enough, resulting in an increase in adverse reactions in patients and a decrease in the success rate of transplantation. The drug toxicity and dosage in the pretreatment regimen are difficult to accurately control, affecting the patient's tolerance and transplantation effect.

[0053] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0054] The working principle of the CART-based personalized hematopoietic stem cell transplantation pretreatment information data method provided by the present invention can be summarized into the following steps:

[0055] First, data collection steps

[0056] Through the data collection module, the system collects detailed clinical and laboratory data of patients. These data include at least the patient's basic information (such as age, gender, etc.), medical history, genomic information, and current immune status. The collection of this information is to establish a comprehensive patient portrait and provide a basis for subsequent data analysis and the formulation of pretreatment plans.

[0057] Second, preprocessing model construction steps

[0058] 1. Using machine learning algorithms and CART technology, the collected data is deeply analyzed through the pre-processing model building module. The purpose of this step is to build a personalized pre-processing model based on the individual characteristics of the patient.

[0059] 2. The model will comprehensively consider the patient's various physiological parameters and disease status to predict the effects of different conditioning regimens. In this way, doctors can optimize the conditioning regimen before hematopoietic stem cell transplantation based on this model.

[0060] Third, solution optimization steps

[0061] 1. The CART optimization module will generate an optimized pretreatment plan based on the personalized pretreatment model established previously and the patient's specific conditions (such as age, physical condition, tolerance to drugs, etc.).

[0062] 2. This optimization plan will list in detail key parameters such as drug selection, dosage adjustment, and administration time. These parameters are determined based on the individual characteristics of the patient and the prediction results of the model to ensure that the conditioning regimen can maximize the success rate of hematopoietic stem cell transplantation and reduce the occurrence of adverse reactions.

[0063] Fourth, monitoring and feedback steps

[0064] 1. During the pretreatment process, the monitoring feedback module will monitor the patient's response to the pretreatment regimen in real time. This includes observing changes in the patient's physiological indicators, drug tolerance, and any adverse reactions.

[0065] 2. Based on the monitoring results, the system will dynamically adjust the pretreatment plan. If the dose of a certain drug is too high and causes discomfort to the patient, the system will recommend reducing the dose or changing the drug; if a certain drug is not effective, the system will recommend other more effective drugs.

[0066] 3. This dynamic adjustment mechanism ensures the safety and effectiveness of the pretreatment process, and also makes the entire pretreatment plan more in line with the actual needs of patients.

[0067] In general, this method uses CART technology, machine learning algorithms and real-time monitoring feedback mechanisms to tailor a personalized hematopoietic stem cell transplantation pretreatment program for patients. This not only improves the success rate of transplantation, but also reduces the risk of adverse reactions, bringing better treatment effects and quality of life to patients.

[0068] The following is a specific implementation example of a CART-based personalized hematopoietic stem cell transplantation pretreatment information data method:

[0069] Patient Information:

[0071] * Age: 45

[0072] * Gender: Male

[0073] *Medical History: Acute Myeloid Leukemia (AML)

[0074] *Genomic information: FLT3 gene mutation is present

[0075] *Immune status: Low

[0076] 1. Data Collection

[0077] The system automatically collects the clinical data of patient P001 through the hospital's information system and laboratory equipment, including blood routine, biochemical indicators, immunophenotyping, gene mutation analysis results, etc.

[0083] Select characteristics related to the conditioning effect of hematopoietic stem cell transplantation, such as age, gender, medical history, gene mutation, immune status, etc.

[0084] Use methods such as principal component analysis (PCA) to reduce feature dimensionality to simplify the model and improve computational efficiency.

[0085] 3. Model training:

[0086] Historical patient data was used as the training set, which included various pretreatment regimens and their corresponding effects (such as transplant success rate, incidence of adverse reactions, etc.).

[0091] 2. Generate optimization plan:

[0092] Based on the input patient characteristics, the model predicts the most suitable pretreatment regimen for patient P001. The regimen includes the type, dose, administration time and cycle of specific chemotherapy drugs.

[0093] For example, the model recommends the use of the FLAG regimen (fludarabine, cytarabine, and granulocyte colony-stimulating factor) for pretreatment and provides specific drug doses and schedules.

[0094] 4. Monitoring Feedback

[0095] 1. Real-time monitoring:

[0097] 2. Plan adjustment:

[0098] According to the monitoring results, if it is found that the patient does not respond well to a certain drug or has adverse reactions, the system will adjust the pretreatment plan in time, for example, reducing the drug dosage, changing the drug or adjusting the administration time.

[0099] The adjusted regimen will be evaluated and optimized again using the CART model to ensure the safety and effectiveness of pretreatment.

[0100] 5. Result output and recording

[0101] The system will output the finalized personalized pretreatment plan to the doctor for reference and execution.

[0215] Genomic information: The patient's genomic data is obtained through gene sequencing technology to analyze genetic mutations related to transplantation.

[0216] Immune status: Assess the patient's immune status, including the types and number of immune cells, antibody levels, etc.

[0217] Step 2: Preprocessing model building

[0218] 1. Data preprocessing:

[0219] Data cleaning: remove noise data and outliers, and fill in missing values.

[0220] Feature extraction: Extract key features from the collected raw data as input variables.

[0221] Feature selection: Through correlation analysis and feature importance evaluation, the most representative features are selected to input into the model.

[0222] 2. Machine Learning Algorithms:

[0223] Select appropriate machine learning algorithms (such as decision trees, random forests, etc.) to build preliminary models.

[0224] 3.CART technology:

[0225] Classification tree: used to classify different characteristics of patients and generate personalized pretreatment strategies.

[0226] Regression trees: used to predict patient response to conditioning regimens and optimize drug selection, dose adjustment, and administration schedule.

[0227] Step 3: CART Optimization

[0228] 1. Personalized preprocessing model:

[0229] Generate personalized preprocessing schemes based on the constructed classification trees and regression trees.

[0230] Drug selection: Select the most appropriate pretreatment drug based on the patient's genomic information and clinical data.

[0231] Dosage adjustment: Adjust the drug dosage according to the patient's weight, liver and kidney function and other physiological indicators.

[0232] Administration time: Optimize the administration time according to the patient's physiological cycle and drug metabolism characteristics.

[0233] 2. Model optimization:

[0238] 2. Dynamic adjustment:

[0239] Based on the real-time monitoring results, the pretreatment plan is dynamically adjusted through the feedback mechanism.

[0240] If adverse reactions are monitored or the expected effects are not satisfactory, adjust the type of drug, dosage and administration time in a timely manner.

[0241] Algorithms and models:

[0242] 1. Data collection and preprocessing:

[0243] Use Pandas and NumPy for data cleaning and feature extraction.

[0244] Feature selection and preliminary model building were performed via Scikit-learn.

[0245] 2. Machine Learning Model:

[0247] The CART model recursively segments the data set and establishes classification and regression rules.

[0248] 3. Model optimization:

[0249] Use Grid Search and Cross-Validation to optimize model parameters and select the best model.

[0250] 4. Real-time monitoring and feedback:

[0251] Data is collected and analyzed in real time through sensors and laboratory testing equipment.

[0252] Use control algorithms (such as PID control) to achieve dynamic adjustment of the pretreatment scheme.

[0253] Through the above steps, the present invention can realize a personalized and dynamically optimized hematopoietic stem cell transplantation pretreatment program, improve the treatment effect, and reduce the risk of complications.

[0254] This implementation scheme uses Python programming language, combined with commonly used machine learning libraries (such as Scikit-learn) and data processing libraries (such as Pandas and NumPy) to implement a personalized hematopoietic stem cell transplantation pretreatment information data method based on CART. The specific steps are as follows:

[0255] Step 1: Data Collection

[0256] ```Python

[0257] import pandas as pd

[0258] import numpy as np

[0259] #Assume that data is read from a database or file

[0260] data=pd.read_csv('patient_data.csv')

[0261] # Display data structure

[0262] print(data.head())

[0263] Step 2: Data Preprocessing

[0264] ```Python

[0265] from sklearn.model_selection import train_test_split

[0266] from sklearn.preprocessing import StandardScaler

[0267] from sklearn.impute import SimpleImputer

[0268] #Data cleaning: Filling missing values

[0269] imputer=SimpleImputer(strategy='mean')

[0270] data_imputed=imputer.fit_transform(data)

[0271] #Feature extraction and selection (assuming all columns are selected as features)

[0272] X = data_imputed[:,:-1] #all feature columns

[0273] y = data_imputed[:,-1] # target column (assuming the last column is the target variable)

[0274] #Data Standardization

[0275] scaler = StandardScaler()

[0276] X_scaled=scaler.fit_transform(X)

[0277] #Dataset Splitting

[0278] X_train,X_test,y_train,y_test=train_test_split(X_scaled,y,test_size=0.2,random_state=42) Step 3: Build CART model

[0279] ```Python

[0280] from sklearn.tree import DecisionTreeRegressor

[0281] from sklearn.ensemble import RandomForestRegressor

[0282] from sklearn.metrics import mean_squared_error

[0283] #Decision tree model

[0284] cart_model=DecisionTreeRegressor(random_state=42)

[0285] cart_model.fit(X_train,y_train)

[0286] # Random Forest Model

[0287] rf_model=RandomForestRegressor(n_estimators=100,random_state=42)

[0288] rf_model.fit(X_train,y_train)

[0289] #Prediction and Evaluation

[0290] y_pred_cart=cart_model.predict(X_test)

[0291] y_pred_rf=rf_model.predict(X_test)

[0292] mse_cart=mean_squared_error(y_test,y_pred_cart)

[0293] mse_rf=mean_squared_error(y_test,y_pred_rf)

[0294] print(f'Mean square error of CART model: {mse_cart}')

[0295] print(f'Mean square error of random forest model: {mse_rf}')

[0296] ```

[0297] Step 4: Generate a personalized pretreatment plan

[0298] ```Python

[0299] defgenerate_treatment_plan(model,patient_data):

[0300] #Generate personalized solutions based on model prediction results

[0301] predicted_response=model.predict(patient_data)

[0302] #Generate specific plans based on the prediction results (drug selection, dosage adjustment, administration time, etc.)

[0303] treatment_plan = {

[0304] 'Drug selection':'Drug A'ifpredicted_response[0]>0.5else'Drug B',

[0305] 'Dose adjustment':'10mg'ifpredicted_response[0]>0.5else'5mg',

[0306] 'Administration time': 'Morning' if predicted_response[0]>0.5 else 'Evening'

[0307] }

[0308] return treatment_plan

[0309] #Assume there is new patient data

[0310] new_patient_data = np.array([patient_info]).reshape(1,-1) #Convert to the input format accepted by the model new_patient_data_scaled = scaler.transform(new_patient_data) #Data standardization treatment_plan = generate_treatment_plan(cart_model,new_patient_data_scaled)

[0311] print(f'Personalized pretreatment plan:{treatment_plan}')

[0312] ```

[0313] Step 5: Monitor feedback and adjust dynamically

[0314] ```Python

[0315] defmonitor_and_adjust(treatment_plan,feedback_data):

[0316] #Assume that the feedback data is the patient response data monitored in real time

[0317] iffeedback_data['reaction']=='negative':

[0318] treatment_plan['dose adjustment'] = 'reduce dose' # adjust dose based on feedback

[0319] eliffeedback_data['reaction']=='positive':

[0320] treatment_plan['dose adjustment'] = 'maintain dose'

[0321] return treatment_plan

[0322] #Assume there is feedback data

[0323] feedback_data={'reaction':'negative'}

[0324] adjusted_treatment_plan=monitor_and_adjust(treatment_plan,feedback_data)

[0325] print(f'Adjusted pretreatment plan: {adjusted_treatment_plan}')

[0326] ```
