ANTI-EGFR ANTIBODY THERAPY BASED ON AN INCREASED COPY NUMBER OF THE EGFR GENE IN TUMOR TISSUES

摘要

The invention relates to an individualized and personalized diagnosis and therapy of cancer based on specific molecular alterations which occur in specific tumor tissue of specific tumor patient populations. The therapy and diagnostic is based on the findings that proliferation and tumor growth of specific EGFR bearing tumor tissue expressing an amplified EGFR gene copy number may be abolished by anti-EGFR antibodies, while other individual molecular alterations such as mutations occurring in tumor tissues are unaffected by the same anti-EGFR antibody treatment.
