The Kaplan–Meier analysis based on the GEO data of individuals with NDMM (GSE2658) indicated that a high level of CCL3 significantly correlated with shorter overall survival in patients with myeloma (56.05 months vs. unreached, HR = 1.943, p = 0.0034; Fig. 6D). This evidence concerns the gene CCL3 and plasma cell myeloma.
