Abstract
It is difficult to determine the cause of high fever in patients with advanced cancer, because they tend to have both neoplastic fever and concomitant bacterial infections with elevated white blood cells and C-reactive protein levels. Procalcitonin has been reported to be a valuable marker for bacterial infections in a wide range of clinical scenarios. However, there have been no studies regarding the usefulness of procalcitonin to differentiate between febrile episodes caused by bacterial infections and neoplastic fever in patients with advanced urological cancer. In the present study, 37 febrile episodes were retrospectively analyzed. Although there were no differences in white blood cell number, C-reactive protein level or body temperature between bacterial infections and non-bacterial infections, procalcitonin levels were significantly higher in the former than the latter. Our findings suggest that measurement of procalcitonin might be valuable to determine the cause of febrile episodes in patients with advanced urological cancer, and can help clinicians to make appropriate decisions for treatment.
