Abstract

The present invention provides a method for constructing a multiple myeloma nomogram based on ten gene characteristics, serum β2-microglobulin and LDH, comprising the following steps: S1, obtaining the gene expression profile GSE24080 of MM patients from the GEO database, and Preprocessing the genes in the gene expression profile GSE24080 to obtain the top 25% of the 5413 genes with the largest variance in expression values; S2, performing WGCNA gene co-expression network analysis on the 5413 genes to identify co-expression functions modules; S3, the correlation between the functional modules and clinical information was evaluated by Pearson correlation test to identify the most significant modules; S4, the genes in the most significant modules were univariately evaluated using Cox proportional hazards model Survival analysis, and a scoring model consisting of the 10 best genes was screened by LASSO regression; S5, a novel nomogram based on the scoring model, serum β2M and high LDH was established to predict the 3-year OS and 5 years OS.

Description

technical field [0001] The invention relates to a multiple myeloma nomogram construction method based on ten gene characteristics, serum β2-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 β2-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 β2-microglobulin and LDH, comp...
