Determining Cancer Aggressiveness, Prognosis and Responsiveness to Treatment

摘要

The invention provides methods of determining the aggressiveness, prognosis and response to therapy for particular cancers, which include comparing the expression levels of one or a plurality of differentially expressed genes from one or more 5 functional metagenes, including a Carbohydrate/Lipid Metabolism metagene, a Cell Signalling metagene, a Cellular Development metagene, a Cellular Growth metagene, a Chromosome Segregation metagene, a DNA Replication/Recombination metagene, an Immune system metagene, a Metabolic Disease metagene, a Nucleic Acid Metabolism metagene, a Post-Translational Modification metagene, a Protein 10 Synthesis/Modification metagene and a Multiple Networks metagene. The method disclosed herein may be particularly suitable as a companion diagnostic for cancer therapies.

主权项

1. A method of determining the aggressiveness of a cancer in a mammal, said method including the step of comparing an expression level of one or a plurality of overexpressed genes and/or an expression level of one or a plurality of underexpressed genes in one or a plurality of cancer cells, tissues or organs of the mammal, wherein the overexpressed genes and the underexpressed genes are from one or a plurality of metagenes selected from the group consisting of a Carbohydrate/Lipid Metabolism metagene, a Cell Signalling metagene, a Cellular Development metagene, a Cellular Growth metagene, a Chromosome Segregation metagene, a DNA Replication/Recombination metagene, an Immune System metagene, a Metabolic Disease metagene, a Nucleic Acid Metabolism metagene, a Post-Translational Modification metagene, a Protein Synthesis/Modification metagene and a Multiple Networks metagene, wherein: a higher relative expression level of the one or plurality of overexpressed genes compared to the one or plurality of underexpressed genes indicates or correlates with higher aggressiveness of the cancer; and/or a lower relative expression level of the one or plurality of overexpressed genes compared to the one or plurality of underexpressed genes indicates or correlates with lower aggressiveness of the cancer compared to a mammal having a higher expression level.
