Abstract
Breast cancer is the most prevalent neoplasm in women. ER+ (Luminal subtype), representing over 70% of breast tumors, is a genetically diverse group. Structural and Numerical-Chromosomal instability initiates tumor development and is recognized as the primary driver of genetic alteration in luminal breast tumors. Genomic instability refers to the increased tendency of cancer cells to accumulate genomic alterations during cell proliferation. The cell cycle check-point response to constant and stable genomic alterations in tumor cells drives this process. The impact of CNV patterns and aneuploidies in cell cycle and proliferation perturbation has recently been highlighted by scientists in Luminal breast tumors. The impact of chromosomal instability on cancer therapy and prognosis is not a new concept. Still, the degree of emerging genomic instability leads to prognosis alteration following cell cycle deregulation by chromosomal instability could be predicted by CNVs-based reclassification of breast tumors. In this review, we try to explain the effect of CIN in the cell cycle that ended with genomic instability and altered prognosis and the impact of CIN in decision-making for a therapy strategy for patients with luminal breast cancer.
期刊介绍:
Oncology Reviews is a quarterly peer-reviewed, international journal that publishes authoritative state-of-the-art reviews on preclinical and clinical aspects of oncology. The journal will provide up-to-date information on the latest achievements in different fields of oncology for both practising clinicians and basic researchers. Oncology Reviews aims at being international in scope and readership, as reflected also by its Editorial Board, gathering the world leading experts in both pre-clinical research and everyday clinical practice. The journal is open for publication of supplements, monothematic issues and for publishing abstracts of scientific meetings; conditions can be obtained from the Editor-in-Chief or the publisher.
