Key result
Biphasic Synovial Sarcoma demonstrated a better 5-year survivorship (65%) compared to spindle-cell synovial sarcoma (56%, P<0.031) and Synovial Sarcoma, NOS (52%, P<0.001).

Histologic subtyping may refine synovial sarcoma prognosis; extends national data but leaves open therapeutic implications.

Absolute Event Rate: 65% vs 56%

This large national database study provides unprecedented demographic and survival data for 34 distinct soft tissue sarcomas, reflecting true overall prognosis in the USA.
Corey et al. (2014) conducted a cohort in Soft tissue sarcomas (n=63,714). Biphasic Synovial Sarcoma vs. Spindle-cell synovial sarcoma was evaluated on 5-year survivorship (p=<0.031). Biphasic Synovial Sarcoma demonstrated a better 5-year survivorship (65%) compared to spindle-cell synovial sarcoma (56%, P<0.031) and Synovial Sarcoma, NOS (52%, P<0.001).
