Nottingham prognostic index

an index based on a combination of three prognostic factors: tumour size (cm x 0.2); lymph node stage (1 = node negative, 2 = 13 metastatic nodes 3 = ³ 4 metastatic nodes;) and histological grade (13, good, moderate, poor). Alternatively, lymph nodes can be classified according to level of involvement. A prognostic index < 3.4 implies a good prognosis, 3.45.4 a moderately good prognosis and over 5.4 a poor prognosis.
