title: Prevalence, concentration, and prognostic importance of proteinuria in patients with malignancies.
abstract: Protein was found significantly more frequently in single urine samples from 504 patients with malignancy (290; 58%) than in 529 controls (119; 22%) (p less than 0.01). Median protein concentration was greater (p less than 0.001) in patients with neoplasia (0.14 g/l) than in controls (0.07 g/l). Actuarial analysis showed a median survival of 4.5 months in patients with proteinuria compared with 10 months in those without (p less than 0.001). The association between proteinuria and shorter survival was statistically significant for patients with gut tumours, lung tumours, and tumours at other sites analysed as a group. Patients with myeloma or urinary tract tumours were not studied. In many patients with malignancy the presence of proteinuria may be associated with a substantially reduced survival time.
