It can be speculated that the elevation of the RDW is due to the inflammation in the prostate already leading to an enlargement of the gland. Thus, the RDW to IPSS relationship is lost after the prostate volume enlargement. In this study, patients treated with surgery also had higher RDW values than patients preferring medical therapy. Before the RDW can be incorporated into clinical practice, it must be confirmed in multiple datasets evaluating broad populations FK506 mouse with BPH to definitively establish validity and generalizability. Future studies that carefully evaluate the RDW in the context of a more complete evaluation of iron metabolism and markers

of inflammation in BPH patients may provide further insight into the mechanisms of

the interaction between the hematologic system PCI-32765 research buy and BPH. A limitation of the present study is that only a few types of parameters were assessed; therefore, the mechanisms that underlie the association of the RDW with BPH remain to be determined by a large-scale study. Another significant limitation of this study is its single-centered character, which makes extrapolation of the results difficult. These limitations notwithstanding, this analysis has several strengths. None of the patients had hematologic pathology or a disorder that may affect the RDW and all of the patients had normal ferritin and vitamin B12. The adjustment for important confounding factors, such as hemoglobin and age, ensured an unbiased estimate for the relationship between the RDW and BPH. The finding of a strong, graded association of the RDW with elevated prostate volume may have important clinical implications. The increase in the RDW may be a consequence of various underlying pathologic processes, for example, inflammatory stress, and may contribute to disease progression in prostate enlargement. Prostate specific antigen and RDW were the significant predictors of treatment type. In this study,

RDW had a stronger association with surgical treatment than PSA. Elucidating how and why an elevated RDW is associated with the risk of surgery better than Epothilone B (EPO906, Patupilone) PSA (Table 4) in BPH treatment may provide an increased understanding of the pathophysiology and improve the targeting of therapies. If confirmed by future studies, the association between the easy, inexpensive RDW and inflammatory markers may, in fact, provide a rational basis to include the RDW in algorithms for surgery risk prediction. This study should prompt further investigation into the association between the RDW and BPH to improve the understanding of pathophysiology.
