Microalbuminuria in Patients with Lung Cancer

Abstract In a prospective study of 102 outpatients with histologically proven lung cancer, the prevalence and prognostic significance of microalbuminuria (urinary albumin excretion > 20 μg/min) were analysed. 65 consecutive outpatients with benign lung disorders served as controls. An immunoturbidimetric assay, sensitive at low concentrations, was used to quantify the albumin excretion rate in timed overnight urine samples. Patients with malignancies had a significantly higher frequency of microalbuminuria (32.4% compared with controls, 13.8%, P P P
