[Risk factors analysis and nomogram model construction of postoperative pathological upgrade of prostate cancer patients with single core positive biopsy].

In patients with single core positive biopsy, if the prostate volume is small or the proportion of tumor in positive core is small, clinicians should be alert to the possibility of postoperative pathology upgrading, preoperative risk stratification should be carefully considered for patients with possible pathological upgrading. This model can be used to predict the pathological upgrade of patients with single core positive biopsy.
