    161 Discussion
    162 Since life expectancy is on steady rise in most developed countries, a decrease in OCM would
    163 also be expected in PCa patients (7). However, only one European institutional analysis
    164 examined OCM in clinically localized PCa patients treated with RP (8). Unfortunately, no
    165 EBRT patients were assessed. Moreover, to the best of our knowledge, no North-American
    166 population-based analysis reported on OCM rates in clinically localized PCa patients treated
    167 with RP or EBRT. Based on this Vaborbactam void, we examined the time trends of OCM rates in clinically
    168 localized PCa patients. We hypothesized that OCM rates decreased in more contemporary
    169 patients relative to their more historical counterparts. We also postulated that the decrease
    170 might be stronger in older than in younger patients. Our analyses yielded several noteworthy
    173 significant and clinically meaningful fashion. The decrease was recorded in the overall cohort
    176 pronounced decrease was recorded in EBRT (slope: -0.29%/year) compared Vaborbactam to RP patients
    178 represented the double of the value recorded in RP patients, even with age adjustment. In
    179 consequence, contemporary EBRT patients still represent very important targets for
    180 improving patient selection based on OCM considerations, even when the general selection of
    181 patients with respect to the competing effect of OCM improved over the past 25 years in a
    182 highly meaningful fashion. To the best of our knowledge, we are the first to demonstrate this
    183 phenomenon in a large North-American cohort of patients. A smaller scale institutional
    184 European study showed the same phenomenon exhibiting a decrease in OCM rates over time

    186 Second, we identified important differences in the magnitude of OCM reduction over time
    187 according to patient age. Specifically, the most pronounced OCM reduction over time was
    188 recorded in oldest patients (≥75 years). Conversely, a much lower albeit non-zero percent
    189 reduction was recorded in the youngest patients. These observations indicate that the prime
    190 targets for improving patient selection criteria for definitive therapy are the oldest and older
    191 patients. Nonetheless, potential benefits in OCM rate reduction may even be expected in
    192 younger individuals. However, the absolute rate of OCM decrease in the youngest category of
    194 translate into meaningful differences in nationwide initiatives, but may not be detectable at
    195 institutional level.
    196 Third, important differences in OCM were also recorded according to ethnicity. Highest
    197 baseline 5-year OCM rate was recorded in African-American patients (11%), followed by
    199 decreased in all three ethnic groups over time. The most significant decrease was recorded in
    202 particularly important, since recently Dess et al. reported that after adjustment for non-
