Abstract:
1. An assay for selecting a subject with invasive or metastatic cancer to be treated with a Hsp90 inhibitor treatment, wherein the Hsp90 inhibitor treatment is an anti-Hsp90 antibody or fragment thereof which binds to human extracellular Hsp90, the assay comprising: a. subjecting a biopsy sample from the subject to immunohistological staining with an antibody or antibody fragment that binds to human extracellular Hsp90 b. measuring the binding of the antibody or antibody fragment to human extracellular Hsp90 on the surface of cells in the biopsy sample; and c. selecting the subject with invasive or metastatic cancer to be treated with the Hsp90 inhibitor treatment where the immunohistological staining shows localization of the antibody or antibody fragment that binds to human extracellular Hsp90 on the surface of cells in the biopsy sample.
