Collaborative Stage

Note 1: Multigene signatures or classifiers are assays of a panel of genes from a tumor specimen, intended to provide a quantitative assessment of the likelihood of response to chemotherapy and to evaluate prognosis or distant recurrence. Oncotype DX and MammaPrint (also called MammoPrint) are two commercially available genomic tests.
Note 2: Code the type of test performed. The same test should be used to record information in CS Site-Specific Factors 22 and 23.
Note 3: This information may not be available at diagnosis and may require follow-up with the physician.
