Abstract :

Breast cancer is the leading cause of cancer-related death in women with the age and sex-standardized incidence rate of ~47.8% as per GLOBOCAN 2020. Additionally, there is about 0.5% increase in the incidence rate per year globally despite decrease in death rates, which is associated with improved awareness and screening resulting in early detection as per American Cancer Society. About 30% of patients with apparent clinical remission present with disease recurrence in course of time as observed up to 24 years’ follow-up studies. In fact, often the actual statistics of patients showing clinical remission remains only an estimate since a majority presents for the initial detection at a considerably late age with a median age of diagnosis about 62 years while the global life expectancy itself is about 73 years. Therefore, considering most of the time the minor initial symptoms being ignored by the patients, a cost-effective and simple detection system seems extremely necessary, which can be incorporated into yearly check-up. Our study was initially based on understanding the role of stemless factors in regulation of AURKA, the highly overexpressed serine-threonine kinase in 94% of breast cancer cases. However, recently a phase III clinical trial of Aliserib as a single agent, reported no better prognosis in a 960-day timeframe compared to the comparator arm consisting of Gemcitabine/Pralatrexate/Romidepsin in relapsed or refractory peripheral T-cell lymphoma proving that AURKA expression may be dispensable during dissemination of the breast cancer stem cells (BCSCs). Factually, despite AURKA was found to be induced in Oct4/Sox2-high cells in breast cancer tissues, the same cells were found to restrain AURKA expression designating entry into an apparently quiescent AURKA-free G0 phase in circulation. These cells were found to be expressing the EMT markers, indicating the progenitors to be directed towards acquisition of mesenchymal phenotype thereby suggesting appropriate intervention(s).
