SINGAPORE — Scientists at the Bioinformatics Institute (BII) and Genome Institute of Singapore (GIS) have made discoveries that could lead to new ways of diagnosing and treating breast cancer.
BII and GIS are research institutes under the Agency for Science, Technology and Research (A*STAR).
The scientists from both institutes used large-scale genomic data of breast cancers, demonstrating the use of computational techniques to increase understanding of diseases and improve patient treatments, a statement said.
Breast cancer is the most frequent cancer diagnosed amongst women, with an estimated 1.67 million new cancer cases worldwide in 2012.
In Singapore, more than 9,000 women were diagnosed with breast cancer between 2010 and 20142.
Breast cancer is also the leading cause of cancer death in females locally.
Dr Benjamin Seet, executive director of A*STAR’s Biomedical Research Council, said, “These findings advance our understanding of breast cancer, which is the most common cancer affecting women in Singapore.”
“More importantly, it allows us to develop precise and effective treatment strategies for these particular types of breast cancer, as well as to discover new drugs for the patients who do not get better,” he said in the statement.
BII scientists identified and characterised two new major classes of invasive ductal carcinoma (IDC), which comprise about 80 per cent of all breast cancers.
The increased knowledge of these genetically and clinically distinct classes will improve the diagnosis, prognosis and treatment of IDC, paving the way for personalised treatment with better patient outcomes.
In a separate study, scientists from GIS discovered a molecular mechanism that can be targeted to treat a more aggressive type of breast cancer, called triplenegative breast cancer (TNBC).
The researchers identified a crucial protein whose increased activity promotes breast cancer metastasis and resistance to paclitaxel, a first line chemotherapeutic agent to treat breast cancer.
Additionally, treating this pathway may also contribute to the prevention of tumour recurrence, which is the main reason for breast cancer patient mortality.
While increased awareness of the need for early detection has led to improved survival in breast cancer patients, the development of improved treatment strategies remains important to further reduce mortality rates. PNA/Bernama
