Abstract: The present invention relates to a test support method which is a means for predicting whether or not pathological complete response (pCR) will be attained when a preoperative chemotherapy with an anticancer drug is performed, the method using a sample (breast cancer tissue section) collected from a breast cancer patient to be subjected to the preoperative chemotherapy. The test support method includes: [1] the step of acquiring a fluorescence image of a breast cancer tissue section, which fluorescence image shows bright spots of fluorescent nanoparticles labeling one or more kinds of breast cancer-related proteins; [2] the step of acquiring at least one index relating to the expression level(s) of the breast cancer-related protein(s) on the basis of the bright spots of the fluorescence image; and [3] the step of acquiring information for predicting pCR by performing an analysis using the above-described at least one index.
