The invention belongs to the technical field of
bioinformatics and medical detection, and particularly relates to a marker combination for
neuroblastoma (NB) noninvasive
risk level grading, a prediction model, a prediction method and application thereof. The marker combination is used for determining the sex, determining whether the month age is greater than 18 months, determining whether
plasma MYCN is amplified, determining whether tumors are metastatic, and determining the content of
neuron-specific
enolase and
lactic dehydrogenase; a
machine learning
algorithm is used for constructing an NB noninvasive risk degree grading prediction model, the comprehensive performance of the
random forest model is optimal, the area value under a subject working characteristic curve reaches 0.956, the sensitivity is 92.9%, the specificity is 82.1%, the accuracy rate is 87.5%, the Kappa value is 0.75, the F1
score is 0.881, and NB middle and low risk patients and NB
high risk patients can be effectively distinguished; the NB non-invasive
risk level grading prediction model constructed by the invention can quickly, accurately and non-invasively perform NB
risk level grading, and has a relatively good clinical application value.
