Synovial sarcoma a DNA flow cytometric study

Abstract

The relationship between DNA content, clinicopathologic findings, and patient survival in synovial sarcoma was investigated. Patient age at diagnosis (P less than 0.001), tumor size (P less than 0.001), and ploidy status (P less than 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.
