A report in the August issue of the Journal of Clinical Oncology indicates that a simple nomogram using age and comorbidity predicts 10-year life expectancy in prostate cancer patients who are considering radical prostatectomy or radiotherapy, according to Reuters.

Pierre I. Karakiewicz, MD, of the University of Montreal and colleagues devised a tool for prediction of 10-year life expectancy after radical prostatectomy or external beam radiation therapy (EBRT) in a large grouping of prostate cancer patients who did not receive secondary treatment.

With each one-year age increase, a 10 percent increase was associated with the overall mortality during 10 years of follow-up, and each one-unit increase in the Charlson comorbidity index was associated with a 40 percent increase in overall mortality.

According to the findings, the nomogram and comorbidity demonstrated 84.3 percent accuracy in predicting the individual probability of 10-year life expectancy after either radical prostatectomy or definitive EBRT, as Reuters reported from the journal.
