Should we abstain from Gleason score 2-4 in the diagnosis of prostate cancer?
The present study shows an independent prognostic impact of GS in biopsy samples classified according to the previous classification. The elimination of GS 2-4 by the ISUP 2005 results in a considerable loss of pretherapeutic prognostic information and therefore should be questioned in particular with regard to the increasing demand for active surveillance regimens.
Knowledge of the predictive factors that are associated with prolonged LOS should identify those patients who may require prompt and efficient discharge planning, early consultation with a home care nurse, or transfer to a convalescent facility. This approach may significantly improve the utilization of hospital resources.
