title: [Port-Site Metastasis of Prostate Cancer after Robot-Assisted Laparoscopic Prostatectomy : A Case Report].
abstract: The incidence of port-site metastasis in urologic laparoscopic surgery is low, especially in prostate cancer, with 4 reported cases to date. A 65-year-old man was introduced to our hospital presenting with gross hematuria and dysuria. His prostate-specific antigen (PSA) level was 3.1 ng/ml. He was diagnosed with poorly differentiated adenocarcinoma of the prostate, Gleason 9 (5＋4), cT3aN0M0 with non-invasive urothelial cancer of bladder (pTaN0M0, low grade). Robot-assisted laparoscopic prostatectomy was performed. Histopathological examination revealed adenocarcinoma, Gleason 9 (5＋4), pT3bN0, and surgical margins were positive. Eighteen weeks postoperatively, local recurrence, lymph node metastases, and a port-site metastasis were observed. Androgen deprivation therapy with 4 courses of induction docetaxel chemotherapy achieved a complete response on imaging study, 2 years postoperatively.
