Symptomatology of metastatic prostate cancer: prognostic significance

Abstract

Objective: To identify the various presenting symptoms in patients with metastatic prostate cancer, quantify the metastatic load for each symptom group and compare their case-specific survival.

Patients and methods: A prospective and consecutive series of 279 men with metastatic cancer of the prostate was analysed. Based on the symptom at presentation, six different groups were identified: bladder outflow obstruction, bone pain, anaemia, weight loss, paraplegia and alteration of bowel habit.

Results: Significant variations were observed in their metastatic load (Kruskal-Wallis test, P = 0.0035) and in case-specific survival (log-rank test, P = 0.0038).

Conclusion: Bladder outflow obstruction, bone pain and anaemia not only dictate treatment selection but we provide evidence that each of these symptoms has considerable prognostic significance in patients with metastatic cancer of the prostate.
