This code generates the results and figures reported in the paper:
Benzekry, S., Sentis, C., Coze, C., Tessonnier, L., & André, N. (2020). Development and Validation of a Prediction Model of Overall Survival in High-Risk Neuroblastoma Using Mechanistic Modeling of Metastasis. JCO: Clinical Cancer Informatics, Vol 5, pp. 81-90.
https://ascopubs.org/doi/full/10.1200/CCI.20.00092
Specifically, the code is composed of python and matlab scripts and jupyter notebooks (in python and R) and performs:
- Statistical analysis of prognosis factors of overall and progression-free survival (Kaplan-Meier, log-rank, Cox regression)
code/statistical_analysis.ipynb
with results exported in statistical_analysis/
- Simulation of a mechanistic model of metastasis
code/main_simulate.m
- Calibration of the model parameters from quantitative clinical data at diagnosis: primary tumor size, lactate dehydrogenase (LDH) and SIOPEN score from nuclear imaging
code/mechanistic.ipynb
with results exported in mechanistic/
- Assessment of the predictive power of patient-specific Cox regression-based models for overall survival
code/mechanistic.ipynb
and
code/cox_r_calibration_plot.ipynb
with results exported in cox_regression
(clinical data alone) and mechanistic/cox_regression
(clinical data + mathematical parameters).
The data used for the analysis is available in data/
The files generating figures and supplementary are available in manuscript/
