title: [Tumor progression and metastasis].
abstract: The heterogeneity of cells capable of metastasation has proved to be the greatest obstacle to successful treatment or to prevention of metastatic diseases. This variety appears to be attributable to processes of selection. Cytobiological investigations which are helpful in casting some light at selective mechanisms of metastasation may, perhaps, make substantive contributions to cancer therapy.
