As genetic tests of breast cancer tissue, HER2 tests, one-step nucleic acid amplification (OSNA), Oncotype Dx, and MammaPrint are available. HER2 tests, comprising immunohistochemistry and fluorescence in situ hybridization (FISH), are used for the decision of indication of trastuzumab therapy. OSNA is an intraoperative molecular diagnosis to detect lymph node metastasis of breast cancer. HER2 tests and OSNA are used in routine diagnostic platform in Japan. Oncotype Dx and MammaPrint are genetic testing to determine the indication of adjuvant chemotherapy by identifying cancer recurrence risk in the patients with hormone receptor-positive breast cancer. In clinical trials overseas, there are data showing the effectiveness of Oncotype Dx and MammaPrint, and these tests are expected to be introduced in routine diagnosis in the future.
