Synovial sarcoma a DNA flow cytometric study

The relationship between DNA content, clinicopathologic findings, and patient survival in synovial sarcoma was investigated. Patient age at diagnosis (P < 0.001), tumor size (P < 0.001), and ploidy status (P < 0.003) correlated significantly with patient survival. A marginally significant correlation between mitotic count and patient survival was also observed (P = 0.04). Histologic subtypes (monophasic) versus biphasic), mitotic count, and S-phase by flow cytometry had no significant influence on the clinical outcome of patients with synovial sarcoma in this study. The authors conclude that DNA ploidy analysis is a significant objective probe in the prognostication of patients with synovial sarcoma.
