Histologic features relating to prognosis in synovial sarcoma.
Although the American Joint Commission has classified all synovial sarcomas as "high grade," histologic subtypes can be identified. By histologically subclassifying synovial sarcoma tumors according to percent glandularity and mitotic rates, the authors were able to define high-risk and low-risk patients. Charts and original pathologic slides were reviewed on 45 synovial sarcoma patients. With a 41-month median follow-up, the low-risk patients showed 100% survival, whereas the high-risk patients showed 37% survival.
