The present study aimed to investigate the clinicopathological implications of histological mapping in radical prostatectomy specimens. The results showed significant correlations between positive surgical margin (PSM) and the largest tumor dimension, tumor volume, tumor surface area, and proportion of the tumor in the histological mappings. These histological parameters can be useful for interpreting PSM after radical prostatectomy.
Objective: The present study aims to elucidate the clinicopathological implications of histological mapping in radical prostatectomy specimens.Methods: This study included 76 prostatic cancers with histological mapping. The examined characteristics from the histological mappings were the largest tumor dimension, distance from the tumor core to resection margin, tumor dimension from the apex to base, tumor volume, tumor surface area, and proportion of the tumor. In addition, these histological parameters from the histological mapping were compared between patients with positive surgical margin (PSM) and negative surgical margin (NSM).Results: Patients with PSM were significantly correlated with a higher Gleason score and pT stage than those with NSM. Among the histological characteristics from mappings, there were significant correlations between PSM and the largest tumor dimension, tumor volume, tumor surface area, and proportion of tumor (P < 0.001, P < 0.001, P < 0.001, and P = 0.017, respectively). The distance from the tumor core to the resection margin was significantly longer with PSM than with NSM (P = 0.024). According to the linear regression test, the tumor volume, tumor surface area, and largest tumor dimension were significantly correlated with Gleason score and grade (P = 0.019, P = 0.036, and P = 0.016, respectively). There were no significant differences in the histo-logical factors between the apical and non-apical involved subgroups.Conclusion: Various clinicopathological characteristics assessed from the histological mappings, such as the tumor volume, tumor surface area, and proportion of the tumor, can be useful for interpreting PSM after radical prostatectomy.
