In this hypothesis-generating study, we explore the prognostic relevance of <i>CCNE1</i> amplification, focusing on its role in shaping the tumor microenvironment (TME). We conducted an <i>in silico</i> analysis utilizing exome sequencing, clinical, and transcriptome data from HGSOC patients available in The Cancer Genome Atlas. <i>CCNE1</i> amplification correlates with significantly reduced overall and disease-free survival in HGSOC patients. Differential gene expression and pathway analyses predicted that <i>CCNE1</i>-amplified tumors associate with replication stress, elevated mitotic activity, and increased chromosomal instability. Importantly, these tumors showed a predicted reprogrammed immune landscape, characterized by elevated stromal content, increased infiltration of M2 macrophages, myeloid-derived suppressor cells, and cancer-associated fibroblasts, alongside reduced expression of antigen-presenting machinery, particularly Human Leukocyte Antigen (HLA) class II genes. Further analysis highlighted a strong association between replication stress and upregulation of Transforming Growth Factor-beta (TGF-β) signaling pathways, which likely contribute to the observed immunosuppressive microenvironment. Together, our data suggested that <i>CCNE1</i> amplification is associated with tumor progression not only through enhanced proliferation but also by adopting an immune-suppressive TME.
