KLK3 and posterior cortical atrophy: Our current study firstly demonstrated the locations of PSM and investigated the correlation between clinicopathological parameters and PSM in PCa patients who underwent LRP with and without NHT, and demonstrated that BMI, PSA, ISUP grade after LRP, pT and pN were independent risk factors affecting PSM for patients without NHT, while pT, pN, and LVI were independent risk factors affecting PSM for patients with NHT.
