How do you approach pathologic review and genomic testing, if indicated, of a spindle cell neoplasm?  

For example, if a biopsy reads: lesion comprised of spindle cells arranged in a fascicular pattern, elongated, hyperchromatic nuclei, focally positive for SMA, negative for WT1, ALK 1, EMA, BCL-2, CD34, desmin. MIB-1 labeling 2 to 3%.  

Do you obtain next-generation sequencing on all sarcomas outside of a clinical trial? If so, how do you utilize them for management, if at all?
