Varying strategies have been evaluated to diagnose and predict risk of prostate cancer more optimally. The presence of local or systemic inflammation has been postulated to be associated with increased risk of the presence and aggressiveness of prostate cancer. Complete blood counts with differential white counts are routinely obtained, and the ratio of platelets to lymphocytes (PLR), neutrophils to lymphocytes (NLR), and monocytes to lymphocytes (MLR) have been proposed as markers of inflammation. In the study by Lee et al., the authors evaluated whether the PLR was associated with benign prostate disease, clinically insignificant prostate cancer (Gleason 6 or lower), or clinically significant prostate cancer (Gleason 7 or higher) in patients undergoing prostate biopsy. In a cohort of 1652 who underwent biopsy, the only significant finding was a lower PLR in patients with clinically significant prostate cancer and a PSA < 10 ng/mL compared with patients having benign disease or clinically insignificant disease.
Rundle et al evaluated whether NLR or MLR in the setting of cancer varied by race, as African American and Black men are at higher risk for prostate cancer than White men. In this case-control study that included 822 cases of prostate cancer and 573 controls, there were no significant differences in the trajectories of NLR or MLR over time between cases or controls in the entire cohort. The NLR and MLR were higher over time for White men without prostate cancer compared with White men with prostate cancer; however, no such difference was identified when comparing Black men with or without prostate cancer. Thus, while there may be some association between inflammation and prostate cancer diagnoses or risk of aggressiveness, the use of PLR, NLR, or MLR requires much more study to fully determine the usefulness of these ratios.
A slightly different approach to improve diagnostic strategies has been to utilize prostate MRI to identify areas of the prostate suggestive of cancer. Eklund et al evaluated the use of MRI in the setting of an organized prostate screening program. The use of MRI with targeted and standard biopsy was noninferior to standard biopsy alone in detecting clinically significant prostate cancer while fewer clinically insignificant prostate cancers were identified in the MRI with targeted and standard biopsy group compared with the standard biopsy group. This study further supports the increasing utilization of MRI as part of a biopsy approach in men at risk for prostate cancer.
