Submitting a Sample
The Oncotype DX® Colon Recurrence Score requires either one tumor block OR 15 unstained slides (5 micron tissue sections). Unused portions of the tumor block will be returned. When submitting a sample for the Oncotype DX Colon Recurrence Score, please choose the one block with both the greatest amount/area of invasive colon carcinoma/associated stroma.
All specimens must be labeled with S barcode labels from the Oncotype DX Colon Recurrence Score Specimen Collection and Transportation Kit Box for that patient.
The pathology requirements for the Oncotype DX Colon Recurrence Score and MMR testing are the same: at least 2 mm of invasive adenocarcinoma or mucinous carcinoma that is formalin fixed and embedded in a paraffin block.
For specimen criteria and specimen preparation instructions, call 866-ONCOTYPE (866-662-6897). If indicated on the Oncotype DX Colon Recurrence Score Requisition Form, Genomic Health® will request the retrieval of the appropriate specimen on your behalf.
