![]() Knowing the shape of an object allows you to choose the proper formula and make the necessary measurements to calculate the volume. What is clinically significant prostate cancer (csPCA)?Ĭlinically significant cancer is usually defined as a Gleason Score of more than or equal to 7 on biopsy.Determine the shape of your object. To avoid unnecessary biopsies, the PSA density cutoff value of 0.18 would be recommendable for determining a prostate biopsy for Japanese males with a serum total PSA level of 4.1-10.0 ng/ml.” In another study, Sasaki et.al conclude: “PSA density was significantly more accurate than other variables in predicting PCa. This readily available parameter can potentially identify men who do not have PCa but have an elevated PSA secondary to benign conditions.” PSA density rather than PSA should be used to evaluate patients at risk of prostate cancer who may need additional testing or prostate biopsy. The optimal cutoffs of PSA density to diagnose csPCa and rule out the presence of prostatic inflammation in patients with an elevated PSA (>4 ng/ml) were 0.10 ng/ml2 in biopsy naïve patients and 0.15 ng/ml2 in patients with a previous negative biopsy. al: “At multivariable analysis adjusting for age, biopsy history, DRE and prostate volume, PSA density emerged as a strong predictor of clinically significant prostate cancer (csPCA) but was not associated with prostatic inflammation. PSA density is preferred over PSA alone as the latter can be elevated in inflammation and in a larger prostate gland.Īs per a study by Bruno et. ![]() Should we use PSA or PSA density to prognosticate prostate cancers? This causes urinary symptoms due to indentation on the posterior bladder wall.
