Abstract: The present invention relates to methods, kits, systems and uses thereof for prediction of the response or resistance to and/or benefit from a cancer immunotherapy of a subject suffering from or being at risk of developing a neoplastic disease, in particular breast cancer, based on the measurement(s) of expression level(s) of at least one marker in samples of said subject. Equally, the present invention relates to methods, kits, systems and uses thereof for predicting the outcome from the cancer immunotherapy treatment in said subject based on the measurement(s) of the expression level(s) of the at least one marker in samples of said subject. Further, the present invention relates to the cancer immunotherapy for use in the treatment of the neoplastic disease, in particular breast cancer, in the subject and to methods for cancer immunotherapy treatment by using the cancer immunotherapy according to the methods of the present invention.

Abstract: The invention provides novel compositions, methods and uses, for the prediction, diagnosis, prognosis, prevention and treatment of malignant neoplasia and breast cancer. The invention further relates to genes that are differentially expressed in breast tissue of breast cancer patients versus those of normal “healthy” tissue. Differentially expressed genes for the identification of patients which are likely to respond to chemotherapy are also provided.
