A bioinformatics method for determining a risk score that indicates a risk that a subject, in particular a human, will experience a negative clinical event within a certain period of time. The risk score is based on a unique combination of activities of two or more cellular signaling pathways in a subject, wherein the selected cellular signaling pathways are the TGF-β pathway and one or more of a PI3K pathway, a Wnt pathway, an ER pathway, and an HH pathway. The invention includes an apparatus with a digital processor configured to perform such a method, a non-transitory storage medium storing instructions that are executable by a digital processing device to perform such a method, and a computer program comprising program code means for causing a digital processing device to perform such a method. The bioinformatics invention allows for more accurate prognosis of specific negative clinical events in a patient with, for example, a tumor or cancer, such as disease progression, recurrence, development of metastasis, or even death.
