Proteinuria and Haematuria are Frequently Present in Patients with Lung Cancer

摘要

The aim of the study was to ascertain whether there is an increased occurrence of proteinuria and/or haematuria among lung cancer patients. As a control group we selected patients with bronchial asthma treated at the same hospital and during the same period as the lung cancer patients.The study comprised a retrospective part, where observations were made at two hosptials on 166 and 284 lung cancer patients. Proteinuria was observed in 9and 13and haematuria in 5and 9of these patients. The prevalences were significantly greater than among the asthmatic patients. This result prompted a prospective case-control study involving 150 consecutive patients with lung cancer and asthma, respectively. Twelve patients in the cancer group and one asthmatic patient had a daily urine protein excretion exceeding 100mg (P<0.004); haematuria was noted in 14 and one, respectively (P<0.002). We conclude that the occurrence of proteinuria and haematuria is unexpectedly increased among patients with lung cancer.
