The object of the study was therefore to assess whether the presence of meEGFR biomarker, when found in CTCs, is predictive of an adverse duration of progression-free survival (PFS) amongst this treatment group. \n \nThe results show that in a prospective study of 47 metastatic colorectal cancer patients, researchers were able to use the Parsortix system to harvest circulating tumour cells (CTCs) and were able to analyse these cells for the presence or absence of meEGFR. \n \nThe total number of CTCs was not correlated to PFS but the proportion of those CTCs that were positive for the meEGFR marker was found to be predictive: patients whose CTCs harvested by Parsortix had a higher proportion of meEGFR positive CTCs, had significantly shorter PFS compared to those patients whose CTCs had lower levels.\n \nThis study is a further demonstration of the effectiveness of Parsortix in enabling liquid biopsy analysis of patients' cancer through a simple blood test with the potential to provide clinically relevant information to advise treatment decisions. \n \n \nDr Scott Kopetz, Associate Professor, Department of Gastrointestinal (GI) Medical Oncology, Division o...
