- In this study we evaluated the safety of expectant approach in the patients with low risk prostate cancer in the reality of community based out-patients clinics. 48 men were enrolled into the study. The inclusion criteria were age ranged from 60 to 75 years and the Epstein criteria for low risk prostate cancer. Patients were managed expectantly while curative treatment was offered when indicated. Initial and final Charlson comorbidity index (CCI) and BMI were assessed for all men. Patients' median follow-up was 81.1 ± 29.1 years. During this study 41.7% of the patients chose active forms of treatment. Cancer was found in 20.8% (n-10) of our patients. Two first sessions of re-biopsy diagnosed 92% of T1c upgrading. Six men with CCI ≥2 died from concomitant disease and no one died from PCa. Significant correlation was found between BMI and final CCI ≥2 (p-0.001). Expectant approach can be considered as self alternative to active treatment model in selected group of patients with well differentiated PCa, however 20.8% of these patients are still at risk of having aggressive form of cancer. Expectant approach is particular beneficial for the patients with CCI 1-2 and high BMI.
