  • Title: Chromosomal analysis and the classification of soft tissue sarcomas.
    Author: Molenaar WM, DeJong B, Buist J, Idenburg VJ, Seruca R, Vos AM, Hoekstra HJ.
    Journal: Lab Invest; 1989 Feb; 60(2):266-74. PubMed ID: 2536862.
    Abstract:
    Seventeen soft tissue sarcomas were karyotyped and the chromosomal findings were compared with those in the literature. Some cases were easily classified (immuno)histologically, whereas others defied classification. In four cases with unequivocal histology, a "characteristic" chromosomal abnormality was found. In one case a diagnosis that was doubtful on histologic grounds was supported by the chromosomal findings, whereas in three other cases, the chromosomal pattern led to reconsideration of the histologic diagnosis. The remaining cases either showed chromosomal abnormalities with hitherto undescribed breakpoints or breakpoints described in tumors with different histology. The results extend the knowledge of chromosomal abnormalities in soft tissue sarcomas. Most importantly, the present approach demonstrates that close collaboration between the surgical pathologist and the cytogeneticist may improve the classification of soft tissue sarcomas.
