The Relation of Clinical and Laboratory Findings to the Survival of Patients with Macroglobulinaemia

The relation of clinical and laboratory findings at the time clinical presentation to subsequent survival was investigated in 204 patients with macroglobulinaemia. It was found that the ten following clinical and laboratory parameters were of prognostic significance and a further twelve were not. The best prognoses were found amongst male patients, patients aged 50-69 years and those with serum IgM paraprotein concentrations of 20-39 g/1, type lambda paraproteins, no Bence-Jones proteinuria or cryoglobulinaemia, only one paraprotein, serum cold haemagglutinin activity, serum albumin above 40 g/1 and serum urea below 10 mmol/1.
