stage migration

A term referring to the 'improved' survival of patients with cancer or other disease by either reclassifying them into different prognostic groups, recognising more subtle disease manifestations, or by using diagnostic modalities that allow the disease to be diagnosed at an earlier stage. The Will Rogers phenomenon results in a ‘zero-time shift’ and improved prognosis without affecting actual survival

Tumour-node-metastasis (TNM) staging, as well as pathological nuclear (Fuhrman) grading system, has been identified as a reliable and accurate prognosticator in RCC.[sup.6]-[sup.8] There have been reports of a shift towards smaller renal tumours with an associated downwards stage migration,[sup.9]-[sup.11] with an associated improved cancer-specific survival.[sup.12] This stage migration towards smaller lower stage tumours, however, was not observed in an Australian series; an upward histological migration was demonstrated.[sup.13]
