Embodiment 1
[0042] Such as figure 1 As shown, this embodiment provides a method for predicting the prognosis of gastric cancer metabolic genes, comprising the following steps:
[0043] S1: Obtain the sample to be tested, and detect the RNA expression levels of multiple genes, including DYNC1I1 gene, GPER1 gene, MFAP2 gene, ARRB1 gene, C3 gene and GLI1 gene;
[0044] S2: Calculate the gastric cancer prognosis risk score according to the detected expression levels of multiple genes.
[0045] Most preferably, the calculation expression of the gastric cancer prognosis risk score is:
[0046] RiskScore 6 =0.38585*exp DYNC1I1 +0.10411*exp GPER1 +0.04476*exp MFAP2 -0.70386*exp ARRB1 +0.09187*exp C3 +0.21797*exp GLI1
[0047] In the formula, RiskScore 6 is the prognostic risk score for gastric cancer, exp DYNC1I1 is the expression level result of DYNC1I1 gene based on the natural constant e, exp GPER1 is the expression level result of GPER1 gene based on the natural constant e, exp M...
Embodiment approach
[0048] As an optional implementation, the method further includes: loading the detected expression levels of multiple genes into a pre-established and trained classifier, calculating the gastric cancer prognostic risk score, and calculating the gastric cancer prognostic risk score greater than the preset The samples to be tested at the risk threshold are divided into a high-risk group, otherwise they are divided into a low-risk group.
[0049] As a preferred embodiment, the method also includes:
[0050] In this example, calculate the RiskScore 6 After that, the RiskScore 6 Perform Z-score transformation into Risk Score (data standardization), and divide samples with Risk Score greater than zero into the high-risk group, and samples less than zero into the low-risk group.
[0051] This embodiment also provides a gastric cancer metabolic gene prognosis prediction device, including:
[0052] The data acquisition module is configured to: acquire the expression levels of multip...
