摘要:

目的： 探讨前列腺穿刺活检标本中神经周围侵犯（PNI）对根治性前列腺切除术患者预后的影响。方法： 回顾性分析经耻骨后根治性前列腺切除术或腹腔镜根治性前列腺切除术的160例局限性前列腺癌患者的临床资料，所有患者术前均进行前列腺穿刺活检并进行常规石蜡切片后行苏木精-伊红染色，以肿瘤细胞浸润神经束或神经束膜判定为PNI阳性。分析标本中PNI与前列腺癌临床病理特征以及根治性前列腺切除术预后的关系。结果： 160例前列腺癌患者中PNI阳性27例（16.9%）。PNI与前列腺穿刺活检Gleason评分、前列腺癌临床分期、手术切缘阳性有关（P<0.05）。PNI阳性组患者在根治性前列腺切除术后无生化复发生存期为（75.79±6.38）个月，明显短于PNI阴性组的（88.46±2.41）个月（P<0.05）。PNI阳性组患者的总生存期为（84.32±2.96）月，而非PNI组总生存期为（94.50±2.38）个月（P<0.05）。结论： 前列腺穿刺标本中PNI可作为判断前列腺癌患者根治性前列腺切除术后不良预后的指标。

Abstract:

Objective ： To investigate the relationship between perineural invasion (PNI) in prostate biopsy and radical prostatectomy outcomes. Methods: One hundred and sixty patients undergoing radical prostatectomy were analyzed retrospectively. Paraffin sections of the specimens from all patients who underwent prostate biopsy were stained with HE. PNI-positive was defined as infiltration of carcinoma cell into the perineurium or neural fascia. The association of PNI with clinicopathologic features of prostate cancer and radical prostatectomy outcomes were analyzed. Results：PNI was positive in 16.9%(27/160) of the patients. The prostate biopsy Gleason score，clinical staging of prostate cancer，surgical margin were significantly associated with PNI (P<0.05). The biochemical-recurrence-free survival time of PNI-positive patients after radical prostatectomy was shorter than that of the PNI-negative patients [(75.79+6.38) months vs (88.46+2.41) months, P<0.05]. Furthermore, the overall survival time of PNI-positive patients was shorter than that of the PNI-negative [(84.32+2.96) months vs (94.50+2.38) months, P<0.05]. Conclusion： PNI in prostate biopsy can be used as one of the indicators to predict adverse prostatectomy outcomes.
