It is a re-resection specimen. The BCRs pathologists reviewed the TSS frozen top slide, the 3 BCR frozen top slides, and the 25 diagnostic FFPE slides from the initial resection. The initial resection contained myxofibrosarcoma. The frozen top slides of the TCGA tumor do not show any tumor, only reactive tissue. |
