Manchester score

Overview
Manchester score is an indicator of prognosis in small cell lung cancer. It is calculated from a number of physical and biochemical markers.

A patient with small cell lung cancer scores one point for each of the following: -
 * Serum lactate dehydrogenase exceeds the upper limit of the reference range.
 * Serum sodium concentration less than 132 mmol/l.
 * Serum alkaline phosphatase over one-and-a-half times the upper limit of the reference range.
 * Serum bicarbonate less than 24.
 * Karnofsky performance status less than 60.
 * Extensive stage disease.
