The invention relates to the technical field of prognosis analysis, in particular to a
pancreatic cancer prognosis analysis
system based on
big data mining, which comprises a jump
trend extraction module, an index grade mapping module, a
sample stability screening module, a path node offset identification module and a prognosis
stage classification module. According to the method, a change
rate difference value and a third-order response sequence are constructed for continuous three-stage
pancreatic cancer biological index sequences, jump trend feature points are extracted, and a risk grade transition sequence is formed in combination with grade span and direction judgment; multi-dimensional normalized parameters of a variable coefficient, a survival
score difference value and an
organ function score standard deviation are introduced to perform stable sample screening, interference of data disturbance on a path judgment result is reduced, and path
mutation node positions are screened in combination with a
path stability threshold value; precise classification and marking of high-risk variation stages in prognosis paths of
pancreatic cancer patients are realized, stage reference is provided for individualized intervention strategies, and
risk identification sensitivity and layered intervention scientificity are improved.
