ABSTRACT
Objective To investigate the efficacy and safety of salvage radical prostatectomy for men with recurrent prostate cancer (PCa) after radiotherapy.Method Ten pathologically confirmed PCa patients who relapsed after radiotherapy from Jan.2008 to Dec.2013 were retrospectively reviewed.The mean age was (64.7 ±3.7) years,with range from 56 to 72 year.Local recurrence was confirmed by retransrectal biopsy.All patients had increased PSA and/or lower urinary tract symptoms.Pelvis MRI and bone scan were performed to detect lymph node involvement and bone metastasis.All patients received radical prostatectomy with standard pelvic lymphadenectomy.Seven received open surgery (open group),three patients underwent laparoscopic surgery (laparoscopic group).Postoperative complication and PSA level were compared.Results Salvage radical prostatectomies with lymph node dissection were performed in all patients without major complications.The mean operation time of open group versus laparoscopic group were (225 ± 57)min vs.(210 ± 80)min and the mean blood loss was (275 ± 49)ml vs.(260 ± 93) ml,both of which were with no significant difference (P ＞ 0.05).The average length of stay was (14 ± 4) vs.(8 ± 2) day with significant difference (P ＜ 0.05).No rectal injury was observed.Two (20％) patients were with positive margin,and three (30％) patients had postoperative complications,including one case of deep vein thrombosis,one case of incision infection and and one case of anastomotic leakage.After a mean of 20.6 months'follow-up,two patients (25％) reached biochemical recurrence.Conclusion Both open and laparoscopic salvage radical prostatectomies after radiotherapy failure were feasible.Largescaled prospective studies were needed to verify the long-term effectiveness.
ABSTRACT
Objective To explore the safty and feasibility of transrectal ultrasound guided transperineal seminal vesicle biopsy in the evaluation of clinical staging of prostate cancer.Methods Retrospectively study 57 suspected prostate cancer patients with seminal abnormality during 2010.7-2015.1,age ranged from 50 to 78 years,average 65 ±7 years,serum total prostate specific antigen (tPSA) 3.2-131.1 μg/L, average (23.7 ± 11.3) μg/L.Twenty-two cases had palpable prostate nodules through rectal examination.All the 57 patients underwent ultrasound and template guided transperineal prostate and seminal vesicle puncture biopsies.Results Forty-four cases out of 57 found prostate cancer cells in biopsies, and 32 cases had seminal vesicle invasion (positive group) while the other 12 were negative.Twenty cases had been performed prostatectomy in the positive group and their post-operative pathological examination all showed prostate cancer with seminal vesicle invasion.Eleven cases in the negative group had been performed prostatectomy ,and 2 cases showed seminal vesicle invasion.The clinical stages of all cases in the positive group were considered as T3b both pre-operatively and post-operatively.In the negative group however, 11 cases were considered as T2 stage pre-operatively,while 2 cases were increased to T3b stage post-operatively.The sensitivity of puncturing seminal vesicle was 91％ (20/22) ,specificity was 100.0％ (9/9).Positive predictive value was 100.0％ (20/20),while negative predictive value was 82％ (9/11).All the 57 cases did not present fever after puncture biopsies, while 23 cases presented hematuria (40％) ,20 cases presented hemospermia (35％) and 1 case presented urinary retention (2％).Conclusions Transrectal ultrasound-guided transperinealseminal vesicle puncture is safe and reliable, it helps to improve the accuracy of pre-operative staging.
