Recent understanding of the periprostatic anatomy has led to an anatomical approach to radical prostatectomy, with reduced complications. Initially, a technique for management of the dorsal vein complex was developed that enabled the surgeon to perform a precise anatomic dissection at the apex of the prostate. Subsequently, the precise anatomy of the pelvic plexus and the branches that innervate the corpora cavernosa was studied. This led to the development of nerve-sparing radical prostatectomy. With the increasing chance of finding an early stage prostate cancer, radical prostatectomy has gained wide popularity even in Japan. On the other hand, the indications for radical prostatectomy are still controversial, especially for locally advanced (stages C) prostate cancer. Surgical staging is considered to be mandatory, because once pelvic lymph node metastases are identified, the prognosis is unfavorable irrespective of the mode of treatment. Minimally invasive approaches including laparoscopic pelvic lymphadenectomy have been developed for lymph node staging. The significance of the neoadjuvant hormonal treatment for locally advanced prostate cancer should be carefully discussed with regard to the long-term outcome.
近年来对前列腺周围解剖结构的认识促使人们采用解剖学方法进行根治性前列腺切除术,并发症有所减少。最初,开发了一种处理背静脉复合体的技术,使外科医生能够在前列腺尖部进行精确的解剖分离。随后,对盆腔神经丛及其支配海绵体的分支的精确解剖结构进行了研究。这促成了保留神经的根治性前列腺切除术的发展。随着发现早期前列腺癌的几率增加,根治性前列腺切除术即使在日本也广受欢迎。另一方面,根治性前列腺切除术的适应证仍存在争议,特别是对于局部晚期(C期)前列腺癌。手术分期被认为是必不可少的,因为一旦发现盆腔淋巴结转移,无论治疗方式如何,预后都不理想。包括腹腔镜盆腔淋巴结清扫术在内的微创方法已被用于淋巴结分期。对于局部晚期前列腺癌的新辅助激素治疗的意义,应就长期疗效进行仔细讨论。
