Abstract

The invention provides a method for constructing a nomogram of multiple myeloma based on ten gene characteristics, serum [beta]2 microglobulin and LDH. The method comprises the following steps: S1, obtaining a gene expression profile GSE24080 of an MM patient from a GEO database, and pre-treating genes in the gene expression profile GSE24080 to obtain the first 25% of the 5413 genes with the largest variance in expression values; S2, subjecting the 5413 genes to WGCNA gene co-expression network analysis to identify function modules of co-expression; S3, evaluating the correlation between the functional modules and clinical information by Pearson correlation test to determine the most significant module; S4, performing univariate survival analysis on the genes in the most significant modules using a Cox proportional hazard model, and screening a score model consisting of 10 best genes by LASSO regression; and S5, establishing a novel nomogram based on the scoring model, serum [beta]2M and high LDH to predict 3-year OS and 5-year OS of newly diagnosed MM patients.

Description

technical field

[0001] The invention relates to a multiple myeloma nomogram construction method based on ten gene characteristics, serum Ξ²2-microglobulin and LDH. Background technique

[0002] Multiple myeloma (MM) is a malignant plasma cell disease in which tumor cells originate from plasma cells in the bone marrow, which are cells that develop to the final functional stage of B lymphocytes. At present, the heterogeneity of multiple myeloma has been paid more and more attention. However, no effective and simple MM prognostic model has been established in the world. Contents of the invention

[0003] The present invention provides a multiple myeloma nomogram construction method based on ten gene characteristics, serum Ξ²2-microglobulin and LDH, which can effectively solve the above problems.

[0004] The present invention is achieved like this:

[0005] A method for constructing a multiple myeloma nomogram based on ten gene signatures, serum Ξ²2-microglobulin and LDH, comp...
