Abstract

OBJECTIVE

The purpose of this research was to investigate how different types of immune cells impact the outlook of individuals with breast cancer, as well as identify the essential genes associated with immune cell subtype enrichment.

METHODS

The Cancer Genome Atlas (TCGA) database and Gene Expression Omnibus (GEO) database were used to obtain global transcriptome sequencing data sets of breast tissue. The study utilized the CIBERSORT algorithm to determine the presence of 22 different types of immune cells in both breast cancer tissue and normal breast tissue.Immune cell infiltration content was utilized to conduct univariate COX analysis in order to identify risk factors linked to breast cancer prognosis.

RESULTS

Univariate COX analysis indicates that Macrophages M1 and B cells naive are beneficial factors for the outlook of individuals with breast cancer (P < 0.05), while Macrophages M2 and Monocytes are detrimental factors for the prognosis of breast cancer patients (P < 0.05). The high infiltration group of macrophage M2 had a poorer prognosis compared to the low infiltration group (P < 0.001); Conversely, the high infiltration group of macrophage M1 had a better prognosis than the low infiltration group (P = 0.002).

CONCLUSION

The study provided an overview of immune cell infiltration in breast cancer tissues, identifying macrophage M1 and macrophage M2 as potential factors in breast cancer development and progression. Additionally, genes associated with macrophage phenotype were analyzed, offering insights into macrophage polarization mechanisms.

摘要

目的

本研究旨在探讨不同类型的免疫细胞如何影响乳腺癌患者的预后，并确定与免疫细胞亚型富集相关的关键基因。

方法

利用癌症基因组图谱（TCGA）数据库和基因表达综合数据库（GEO）获取乳腺组织的全转录组测序数据集。本研究采用CIBERSORT算法来确定乳腺癌组织和正常乳腺组织中22种不同类型免疫细胞的存在情况。利用免疫细胞浸润含量进行单因素COX分析，以确定与乳腺癌预后相关的危险因素。

结果

单因素COX分析表明，M1型巨噬细胞和幼稚B细胞是乳腺癌患者预后的有利因素（P < 0.05），而M2型巨噬细胞和单核细胞是乳腺癌患者预后的不利因素（P < 0.05）。M2型巨噬细胞高浸润组的预后比低浸润组差（P < 0.001）；相反，M1型巨噬细胞高浸润组的预后比低浸润组好（P = 0.002）。
