 Five-year survival rate measures survival at 5 years after diagnosis.In cancer research, various types of survival rate can be relevant, depending on the cancer type and stage.These include the disease-free survival (DFS) (the period after curative treatment [disease eliminated] when no disease can be detected), the progression-free survival (PFS) (the period after treatment when disease [which could not be eliminated] remains stable, that is, does not progress), and the metastasis-free survival (MFS) or distant metastasis–free survival (DMFS) (the period until metastasis is detected).
