Provided is a method for analysing the expression of one or more biomarker RNA molecules, comprising (A) isolating RNA from circulating tumor cells obtained from a subject, determining the expression of at least one biomarker RNA molecule in the isolated RNA and providing an expression profile based on the results; (B) isolating RNA from extracellular vesicles obtained from the subject, determining the expression of at least one biomarker RNA molecule in the isolated RNA and providing an expression profile based on the results; and (C) using the expression profiles determined in (A) and determined in (B) for a combined analysis of the results. Such combined analysis of the CTC and EV expression profiles enhances the prognostic and predictive value of the obtained results and can provide valuable diagnostic, prognostic and/or predictive information. The present method can thus be used as improved diagnostic, prognostic and/or predictive aid in the management of cancer patients. It can be used to support the diagnosis, prognosis or to choose the most appropriate treatment for cancer patients.
