To conduct this study, the authors queried the retrospective SEARCH database using American Society of Anesthesiology (ASA) score at the time of prostatectomy as a surrogate for comorbidity (ASA 1-2 vs 3-4). There were 3,102 men who underwent radical prostatectomy between 1992 and 2015, including 54% men with ASA score 3-4. These men tended to be older, had more recent radical prostatectomy, higher BMI, and higher biopsy Gleason score when compared to men with ASA 1-2. Not surprisingly, men in the higher ASA group had an increased risk of all-cause mortality compared to men in the lower ASA group (HR 1.59, p<0.001). Importantly, there was no increased risk of biochemical recurrence (p=0.23), metastasis (p=0.22), or prostate cancer specific mortality (p=0.83). The strength of this study is the large sample size with long follow-up and granular variable details to allow analyses of long-term prostate cancer specific outcomes.
In summary, men who underwent radical prostatectomy for prostate cancer with worse baseline health had a higher risk of all-cause mortality but did not have higher risk of the adverse prostate cancer specific outcomes of biochemical recurrence, metastasis, or death from prostate cancer. This work is important and further highlights that a life-expectancy calculation/discussion is necessary when discussing potential treatment options with newly diagnosed prostate cancer patients.
