Predictors of cancer disease progression improve patient selection for metastasis-directed therapy

Tumor metastasis, the ability of cancer cells to migrate from their tissue of origin and colonize elsewhere in the body, accounts for over 90% of cancer deaths. When patients die from cancer, it is usually caused by distant ...
