Purpose
We evaluated the influence of age and comorbidity (Charlson score assessment) on localized prostate cancer therapeutic management and the risk of prostate cancer over- and under-treatment.
Methods
Among the 2571 prostate cancer cases diagnosed in 2011, a subset of 633 patients was randomly selected from the prospectively accrued cohort of the Regional Cancer Registry, among the 17 participating institutions. Treatment distributions were examined for patients at each individual prostate cancer risk, age and comorbidity level and analyzed by multivariate logistic regression analysis.
Results
Treatments with curative intent were observed less often when age increased (p < 0.001). We found no impact of the Charlson score on the selection of a curative treatment [HR 0.89, 95 % CI (0.70–1.15)]. A 20 % overtreatment rate was reported in low-risk prostate cancer patients. For younger patients (65–75 years) with high comorbidity score, a 14 % overtreatment rate was observed. Conversely, a 16 % undertreatment rate was reported in older patients >75 years without any significant comorbidity.
Conclusion
A better consideration of comorbidities could significantly reduce overtreatment in patients <75 year and promote curative treatment in aggressive prostate cancer for older patients without any significant comorbidity.
