A collaboration between National Cancer Centre Singapore (NCCS) and Clearbridge BioMedics, in partnership with the Pathology Department at Singapore General Hospital (SGH) has resulted in the establishment of the region's first Circulating Tumour Cell Centre of Research Excellence (CTC CoRE). This new Centre facilitates the use of circulating tumour cells (CTCs) in clinical diagnostics, in order for new technologies to be applied by healthcare institutions.
The CTC CoRE is a key enabler in Singapore's efforts to advance the development of personalised medicine, which is the customised healthcare of an individual patient. The research being undertaken at the CTC CoRE aims to understand the genetic make-up of a patient's cancer cells, which can evolve over time.
To determine the effectiveness of treatment, blood samples will be drawn from the patient pre- and post-treatment. The blood samples are sent to the Cytology Lab at SGH and put through the ClearCell- FX system to separate the cancer cells from other blood components. Using a cytogenetic test, the number of cancer cells are counted and documented. If there is no significant reduction in the number of cancer cells, the oncologist may decide to modify the treatment regime to best combat the cancer. Not only does this result in a dramatic effectiveness in cancer therapy management, it also leads to reduced side effects and significant cost savings.
The CTC CoRE is located at the newly-opened Academia, within SGH's 12,000 sqm Pathology Department. This allows researchers at the CTC CoRE to have access to the cytology, immunohistochemistry, cytogenetics and molecular capabilities at the Department.
The CTC CoRE will focus on a number of research programmes and clinical trials at NCCS and SGH, with support from Clearbridge BioMedics. These include the pilot use of the ClearCell- FX system, which is Clearbridge BioMedics' novel label-free enrichment system for CTCs, first invented at the National University of Singapore. The CTC CoRE will also be developing novel CTC diagnostic assays for personalised medicine that will enable clinicians to tailor therapies to individual patients' unique genetic make-up. It is envisioned that these diagnostic assays will eventually be adopted as part of routine clinical service, enabling clinicians to obtain real-time feedback on therapeutic effectiveness, in order to improve cancer management and patient outcomes.
