Different results: Metastasis arises from primary, the former being clonal and the primary, polyclonal. What spreads to a site such as liver or lung can only grow within that parenchyma and never spread elsewhere. The primary has multiple clones each only capable of spreading to a local site and growing there. Thus primary should always be removed and met focal disease treated later for best survival.
