ABSTRACT
Objective:To explore the quality differences of systemic biopsy specimens from different regions in prostate biopsy.Methods:The data of 806 patients who underwent transperineal prostate biopsy from May 2013 to December 2020 in Northern Jiangsu People’s Hospital were retrospectively reviewed. The median age of the patients was 72 (66, 77) years old, median PSA was 18.4 (10.3, 34.2) ng/ml, and prostate volume was 43 (32, 56) ml. Tissue quality were graded from low to high as follows. One score means multiple fragments with fragmented tissue ≤5 mm. Two scores means at least one fragment >5 mm and ≤10 mm. Three scores means at least one fragment >10 mm. The prostate specimens fragmentation scores and the length of the specimens in different regions of the prostate were collected to analyze.Results:A total of 806 patients were included in our study. The number of tissues was 8 866, and the mean length of tissues was 1.2 (1.0, 1.5) cm. The tissues of different region were scored according to the scoring criteria, of which 618 (7.0%) prostate tissues were scored as 1 score, 2 720 (30.7%) tissues were scored as 2 scores, and 5 528 (62.4%) tissues were scored as 3 scores. In the prostate apex, tissue quality of 1 score accounted for 11.7%(94/806), 2 scores accounted for 34.7%(280/806), and 3 scores accounted for 53.6%(432/806). While in the prostate base, tissue quality of 1 score accounted for 6.5%(524/8 060), 2 scores accounted for 30.3%(2 449/8 060), and 3 scores accounted for 63.2%(5 096/8 060)( H=35.850, P<0.05). The mean length of the prostate apical tissue was 1.0 (0.8, 1.3) cm, which was significantly shorter than prostate basal tissue of 1.2(1.0, 1.5) cm ( Z=-11.353, P<0.05). Conclusions:In transperineal prostate biopsy, the apical tissue was more fragmented and shorter, prostate apex should be concerned.
ABSTRACT
Objective:To investigate the effect of local anesthesia in patients with a PI-RADS score of 5 and ECOG score ≥2 for prostate puncture.Methods:Retrospective analysis of case data of 33 patients admitted to the Subei People's Hospital for prostate puncture from April 2020 to April 2022. Age (82.5±3.6) years. There were 18 cases with hypertensive disease, 8 cases with diabetes mellitus, and 6 cases with both diabetes mellitus and hypertensive disease. Body mass index (25.2±3.5) kg/m 2. prostate-specific antigen (PSA)(131.5±69.7) ng/ml. prostate volume (38.5±21.4) ml. all patients had a PI-RADS score of 5 on multiparametric magnetic resonance (mpMRI) and an Eastern Cooperative Oncology Group (ECOG) score ≥2. All 33 cases in this group underwent trans-perineal targeted prostate puncture using local anesthesia at the tip of the prostate. The visual analog score (VAS) and visual numeric score (VNS) were applied by the same surgeon to assess the patient's pain level and satisfaction at the time of puncture (VAS-1 and VNS-1) and 30 min after puncture (VAS-2 and VNS-2), and to record the duration of the procedure and the occurrence of postoperative complications. Results:In this group of 33 cases, the VAS-1 score was (1.9±0.3) and the VAS-2 score was (0.1±0.2); the VNS-1 score was (2.9±0.2) and the VNS-2 score was (3.9±0.1). Postoperative pathological results indicated that one of the 33 patients had a negative puncture result (pathology report indicating interstitial inflammation), while the rest of the patients had a positive puncture pathology report (puncture pathology report indicating prostate cancer), with a positive rate of 97%. One case of postoperative carnal haematuria occurred, which gradually improved after the patient was advised to drink water and take alpha-blockers. No perineal hematoma occurred, and all patients did not suffer complications such as urinary tract infection, urinary retention, azoospermia, vagal reaction, and infectious shock.Conclusion:In patients with a PI-RADS score of 5 and ECOG score ≥2, the use of single-hole local anesthesia for performing trans-perineal targeted puncture biopsy has the advantages of good paroxysmal pain and high safety.
ABSTRACT
Objective:To explore the feasibility and safety of the clinical application of the diagnosis and treatment mode combining rapid frozen pathological examination of prostate biopsy tissue with radical prostatectomy.Methods:Suspected prostate cancer patients with PSA>10 ng/ml and PI-RADS score ≥4 in, Northern Jiangsu People's Hospital from April to September 2021 were collected. The included patients underwent mpMRI/TRUS image fusion-guided transperineal prostate targeted biopsy with 16G biopsy needle, 2-3 needles for biopsy, and rapid frozen pathological examination. Robot-assisted laparoscopic radical prostatectomy (RALP) was performed immediately for patients with prostate cancer with rapid freezing pathology. For undiagnosed prostate cancer, 18G biopsy needle for prostate targeted + systematic biopsy were used, 18-22 needles for systematic biopsy, and routine pathological examination. The baseline data, frozen pathological results, perioperative conditions, pathological results and follow-up data of all patients were collected.Results:Eleven patients were included in the study, the mean age of the patients was 69.9(66-73) years, the mean BMI was 22.8(19-26) kg/m 2, the mean PSA was 23.2(14.25-32.00), the mean prostate volume was 45(32-52) ml, mean PSAD 0.54(0.33-0.75). PI-RADS score was 4 in 3 cases and 5 in 8 cases; digital rectal examination was positive in 5 cases. All 11 cases underwent rapid freezing and the pathological results showed that: 9 cases were prostate adenocarcinoma, and RALP was performed immediately. The operation time was 111.5(96-126) min, the intraoperative blood loss was 78.9(55-105) ml, and the postoperative extubation time was 4.3(3.5-5.0) days, postoperative hospital stay 5.8(5.0-6.5) days. Postoperative pathology showed that Gleason score 3+ 4=7 in 1 case, 4+ 3=7 in 3 cases, 8 points in 4 cases, and 10 points in 1 case; 3 cases had positive resection margins, and 1 case had seminal vesicle invasion, the average number of dissected lymph nodes was 10.9 (8.5-14.0), and there was no tumor metastasis. Pathological T staging included 2 cases of T 2b stage, 5 cases of T 2c stage, 1 case of T 3a stage, and 1 case of T 3b stage. Two patients were undiagnosed by rapid freezing pathology, of which one was prostate adenocarcinoma with a Gleason score of 4+ 3=7, and then received RALP; the other one was prostate inflammation. 11 patients were followed up; the postoperative follow-up time was 3-7 months, with an average of 5.2 months. Among the 10 patients who underwent RALP, 8 patients recovered urinary continence 2 weeks after surgery, and all recovered within 2 months after surgery. Three patients with positive surgical margins were given regular androgen deprivation therapy in the second week after surgery. PSA did not drop below 0.1 ng/ml in patients with positive margins and seminal vesicle invasion 3 months after surgery. No complications of Clavien grade Ⅰ or higher occurred after operation and during follow-up. Conclusions:For patients with high suspicion of prostate cancer, rapid frozen pathological examination of prostate biopsy tissue is performed. RALP is performed immediately for patients with prostate cancer. The results show that this diagnosis and treatment model could be safe and feasible.
ABSTRACT
The present study retrospectively analyzed the clinical data of 137 patients who underwent prostate in North Jiangsu People's Hospital from June 2020 to May 2021. All patients underwent peripheral prostatic nerve block anesthesia (PPNB). The observation group received 1% ropivacaine 32 ml local, and the control group received the same dose of lidocaine. There was no significant difference in general data before puncture between the two groups ( P>0.05). All 137 cases were performed by the same surgeon. The number of puncture needles in the observation group and the control group was (20.2±2.8) and (20.2±2.9), respectively, and the difference was not statistically significant ( P>0.05). The visual analogue scores (VAS-1) of pain during puncture in the observation group and the control group were (2.62±0.74) and (2.48±0.79) points, respectively. The visual numeric score (VNS-1) was (3.03±0.88) points and (3.15±0.80) points, respectively, and there was no significant difference ( P>0.05). 30 min after puncture, VAS-2 was (0.48±0.53) points and (0.30±0.47) points, VNS-2 was (3.31±0.48) points and (3.55±0.71) points, respectively.The differences were statistically significant ( P<0.05). There was no significant difference in overall complication rate between the two groups ( P=0.661).
ABSTRACT
Objective:To analyze the risk of missed diagnosis in patients with PI-RADS score>3 and negative prostate initial biopsy and to explore its risk factors.Methods:The clinical data of 268 patients with negative prostate biopsy in Northern Jiangsu People's Hospital from May 2013 to December 2018 were retrospectively analyzed. The patients were divided into observation group (PI-RADS score>3) and control group (PI-RADS score≤ 3) according to different PI-RADS scores. There were insignificant differences in age [(67.4(60.0, 74.0)years and 65.6(66.5, 72.0)years], prostate volume of initial biopsy [62.4(40.0, 72.0)ml and 60.8(38.0, 77.0)ml], biopsy cores [ 20.6(18.0, 22.0)cores and 20.4(18.0, 22.0)cores] between the observation group (n=124) and the control group(n=144)(all P>0.05). But there were significant differences in PSA [17.5(6.5, 23.0)ng/ml and 11.5(6.3, 12.0)ng/ml], PSAD[0.316(0.128, 0.363)ng/ml 2 and 0.211(0.106, 0.256)ng/ml 2], prostate inflammation of the initial biopsy [70 (56.5%) and 32 (22.2%)] between the observation group and the control group(all P<0.05). According to the follow-up results after the initial biopsy, the two groups of repeated biopsy were compared.Furthermore, Logistic regression was used to conduct univariate and multivariate analysis to explore the risk factors of patients with PI-RADS>3 for positive repeated biopsy. At the same time, the receiver operating characteristic curve (ROC curve) was used to analyze the accuracy of the risk factors. Results:There were significant differences in repeated biopsy rate [ 27.4%(34/124)and 14.6%(21/144)], CsPCa detection rate[ 41.4%(14/34) and 4.8%(1/21)]between the observation group and the control group(all P<0.05). The positive rate of repeated biopsy in the observation group (41.1%) was higher than that in the control group (23.8%), but there was no statistical difference ( P=0.248). The risk of positive repeated biopsies in the observation group was 2.24 times than that in the control group. Univariate analysis found repeated biopsy PSA ( P =0.02, OR=1.438, 95% CI 1.161-1.896), PSA ratio (repeated biopsy PSA/initial biopsy PSA) ( P=0.011, OR=10.087, 95% CI 1.714-59.36) were risk factors for positive of repeated biopsy in patients with PI-RADS score >3. Multivariate analysis also found that repeated biopsy PSA ( P=0.017, OR=1.15, 95% CI 1.076-2.123), PSA ratio ( P=0.032, OR=10.2, 95% CI 0.883-116.168) were risk factors for positive repeated biopsy. ROC curve analysis, the accuracy of repeated biopsy PSA (AUC=0.971, P<0.001, 95% CI 0.926-1.000), PSA ratio (AUC=0.839, P=0.001, 95% CI0.707-0.971) to predict positive of repeated biopsy were high. The cut-off values were 21.3 ng/ml and 1.4, respectively. The accuracy was higher when combines repeated biopsy PSA with PSA ratio (AUC=0.993, P<0.001, 95% CI 0.974-1.000). Conclusions:Patients with negative PI-RADS score > 3 have a higher risk of missed diagnosis of CsPCa than those with PI-RADS score≤3. When PSA>21.3 ng/ml and PSA ratio>1.4 during follow-up, the possibility of missed diagnosis in the initial biopsy is high.
ABSTRACT
Objective@#To investigate the clinical value of modified transperineal template-guided prostate biopsy (mTTPB) in the detection of prostate cancer.@*Methods@#A total of 217 patients were enrolled in this study. All the patients were randomly divided into 2 groups. The control group (n=112) underwent transperineal template-guided prostate biopsy (TTPB) which was traditional transperineal template-guided 11-region biopsy. On the basis of the control group, the apex of prostate was divided into four areas for biopsy in the observation group (mTTPB). The positive rate of apex and the incidence of complications were analyzed. The prostatic specimens from the radical prostatectomy underwent whole mount sections examination. The prostate biopsy results were compared with the postoperative pathological results.@*Results@#The average age of the control group and the observation group were (68.5±7.9) years and (67.3±8.5) years, PSA were (31.2±18.9) ng/ml and (29.7±19.5) ng/ml, prostate volume were (44.6±15.2) ml and (41.3±17.3) ml, respectively. In the control group, the positive rates of prostate cancer in 1-10 region were 24.1% (27/112), 27.7%(31/112), 23.2% (26/112), 28.6% (32/112), 26.8% (30/112), 25.0% (28/112), 26.8% (30/112), 19.6% (22/112), 25.9% (29/112), 25.0% (28/112), respectively, with an average of 25.3%. In the observation group, the positive rates in 1-10 region were 27.6% (29/105), 28.6% (30/105), 22.9% (24/105), 26.7% (28/105), 25.7% (27/105), 24.8% (26/105), 27.6% (29/105), 21.9% (23/105), 27.6% (29/105), 26.7% (28/105), respectively, with an average of 26.0%. There was no statistical difference between the two groups (P=0.904). The positive rate of apical prostate cancer in the control group and observation group was 37.5% (42/112) and 44.8% (47/105), respectively, and there was no statistical difference between the two groups (P=0.277). Patients were grouped according to PSA>20 ng/ml and PSA≤20 ng/ml. When PSA>20 ng/ml, the positive rate of apex was 58.6% (34/58) and 56.6% (30/53) respectively in the control group and the observation group, and there was no statistical difference between the two groups (P=0.830). When PSA≤20 ng/ml, the positive rate of apex was 14.8% (8/54) in the control group and 32.7% (17/52) in the observation group, with statistically significant differences (P=0.030). Before radical prostatectomy, 12 cases (57.1%) in the control group and 19 cases (73.1%) in the observation group showed apical invasion by biopsy. Results of whole mount sections examination in the control group showed that there were 19 cases (90.5%) with apical invasion, which was statistically different from that before surgery (P=0.035). The results of whole mount sections examination in the observation group showed that there were 23 cases (88.5%) with apex invasion, which had no statistical difference compared with that before surgery (P=0.291). There were no significant differences in the incidence of hematuria, fever, urinary retention and perineal discomfort between the observation group and the control group (all P>0.05).@*Conclusions@#mTTPB can significantly improve the detection rate of apical prostate cancer without increasing the incidence of complications, especially for patients with PSA≤20 ng/ml. Hence is safe and efficacious.

ABSTRACT
Objective@#To evaluate the effect of multimodal analgesia using periprostatic nerve block anesthesia (PNB) combined with flurbiprofen in patients undergoing transperineal template-guided prostate biopsy (TTPB).@*Methods@#Totally 166 patients (aged (68.2±9.1) years, range: 47 to 81 years) who received TTPB from October 2017 to June 2018 at Department of Urology, Northern Jiangsu People′s Hospital Affiliated to Yangzhou University were enrolled prospectively. All the patients were randomly divided into 2 groups. The observation group (n=79) was given flurbiprofen axetil 1 mg/kg intravenously for half an hour before operation and lidocaine was used for PNB before the biopsy. The control group (n=87) was given normal saline combined with PNB. A visual analog scale (VAS) and visual numeric scale (VNS) were used to assess the patients′ pain and quantify their satisfaction at two time points: VAS-1 and VNS-1: during biopsy procedure, VAS-2 and VNS-2: 30 min after the procedure. The date were compared by t test, χ2 test, Fisher exact test and two-way repeated measures anova analysis between the 2 groups.@*Results@#The age, total prostate volume, serum prostate-specific antigen and the number of cores were comparable among the 2 groups (P>0.05). The VAS-1 scores of the control group and the observation group were 2.8±1.7, 1.9±1.2, respectively, and the VNS-1 were 3.1±0.7, 3.4±0.3, respectively. The VAS-1 were significantly lower in observation group than in control group (F=3.904, P=0.000). Conversely, the VNS-1 were higher in observation group (F=3.526, P=0.000). At 30-minute postoperative, the VAS-2 and VNS-2 were 0.7±0.4 and 3.7±0.2 in the control group, respectively. The VAS-2 and VNS-2 were 0.6±0.5 and 3.8±0.1 in the observation group, respectively. There were no significant differences in the pain scores or the satisfaction scores between the 2 groups (F=1.429, 2.825; P=0.136, 0.083). The incidence of overall complications was 26.4% (23/87) in the control group and 25.3% (20/79) in the observation group, with no statistical difference between the 2 groups (χ2=0.027, P=0.869). And the complications had no statistically significant difference among the 2 groups including hematuria, urinary retention, infection, hematospermia, vascular and neurological reactions, nausea, vomiting, dizziness, headache, and respiratory depression (P>0.05).@*Conclusion@#The multimodal analgesia induced by PNB and flurbiprofen could effectively relieve the pain for patients who received TTPB.
ABSTRACT
Objective To investigate the influence factors of periprostatic nerve block (PNB) anaesthesia.Methods A total of 375 patients who underwent prostate biopsy under PNB were analyzed retrospectively from July 2014 to February 2018.It was evaluated the correlation of the anesthetic efficacy of PNB with age,prostate volume,PSA,body mass index,spouse,degree of education,occupation,diabetes history,operation time,number of cores and clinical stage.A visual analog scale (VAS) were used to assess pain of the patients.Univariate analysis was performed for each factor.Factors found to be significantly different that were further analyzed using multiple linear regression analysis.Results The average VAS score of all patients was 2.5 ± 1.4.Univariate analysis showed that the following factors were associated with the anesthetic efficacy of PNB:age (F =2.262,P =0.029),prostate volume (F =2.529,P =0.011),occupation (F =2.203,P =0.042),operation time (F =2.233,P =0.033),number of cores (F =2.401,P =0.016) and diabetes history (F =2.271,P =0.027).Multiple linear regression analysis showed that prostate volume (t =3.742,P ＜ 0.001),number of cores (t =4.252,P ＜ 0.001) and diabetes history (t =-2.242,P =0.032) were independent factors.The VAS score of patients with large volume prostate was higher than that of small volume prostate.The number of cores was high,and the VAS score was higher.However,diabetic patients had lower VAS score.Conclusions The anesthetic efficacy of PNB was poor in patients with larger prostate volume and more number of cores.However,patients with chronic diabetes had better pain tolerance.

Androgen deprivation treatment (ADT) is the gold standard of care for patients with locally advanced or metastatic hormone-sensitive prostate cancer.However,most of these patients have developed to the castration-resistant prostate cancer (CRPC) after months or years through a series of different molecular mechanisms during ADT.So far,CRPC is still incurable and deadly,therefore,it is very important for researchers to study different molecular mechanism in the occurrence and development of CRPC,which may provide some new directions for targeted therapy.
ABSTRACT
Objective To evaluate the erectile function following transperineal template-guided prostate saturation biopsy (TFPSB).Methods From June 2013 to October 2015,patients underwent prostate biopsy.All patients were indicated for biopsy according to the criteria of "Guidance on diagnosis and treatment of urology in China".Exclusion criteria include medical history of PCa,severe urinary tract infection,severe cardiovascular and cerebrovascular diseases or abnormal blood coagulation.All patients were divided into observation group (TT'PSB) or control group (traditional trans-perineal template-guided prostate biopsy,TTPB) according to patients' condition,pubic anatomy,PSA abnormality,rectal examination,imaging examination and pain tolerance,etc.Patients were evaluated for pre-biopsy erectile function with the international index of erectile function (IIEF-5).All pathology confirmed prostate cancer patients were excluded.Concomitant systemic diseases and medications that would interfere with erectile function were recorded.Patients who withdrew from the trial or used the drugs such 5-phosphodiesterase inhibitors for sexual activity improvement were excluded.Ninety-seven patients in observation group and 84 patients in control group underwent further evaluation with the IIEF-5 questionnaire at 1,3 and 6 months post-biopsy.Results The average age of the observation group and the control group were (64.1 ± 7.9) years and (61.8 ±8.9) years,PSA were (7.2 ± 3.7) ng/ml and (6.7 ± 3.4) ng/ml,prostate volume were (47.8 ±21.5)ml and (49.2 ±22.2) ml,and the BMI were (21.4 ±3.1) kg/m2 and (20.6 ±3.4) kg/m2,respectively.There was no significant difference between the two groups (P ＞ 0.05) in term of above patients' characteristics.The pre-biopsy IIEF-5 score of the observation group and the control group were 19.1 ±4.5 and 19.7 ±4.3,which had no significant difference (t =-0.890,P=0.375).One month after biopsy,the IIEF-5 of two groups were 17.4 ±4.8 and 18.2 ±4.5 respectively and both group had statistically significant difference when compared with pre-biopsy (both P ＜ 0.05),however,there was no statistical significance at 3 and 6 months after biopsy.Besides,no significant difference of the IIEF-5 score was detected between two groups in 1,3 and 6 months.Conclusions Although TTPSB may resulted in temporary (1 month) post-biopsy erection dysfunction,the erectile function recovered to pre-biopsy level at 3-6 months post-biopsy.TTPSB did not increase the risk of ED compared with traditional TTPB.

ABSTRACT
Objective To evaluate the efficacy of case management care practice on the self-care ability of the elderly patients with prostate cancer during the endocrine therapy. Methods About 84 patients were divided into two groups by drawing lots. About 41 cases in the control group continued their treatment after discharge and consulted the nurses or doctors by phone call in case of problems. The 43 cases in the observation group was treated with case management for 3 months. The self-care ability was compared between the groups before and after the intervention. Result After the intervention, the ESCA total score of the observation group, self-care skills, self protection responsibility and health knowledge level were significantly higher than that of the observation group before intervention and that of the control group (P<0.05). Conclusion Implementation of the case management can improve the self-care ability, health knowledge level, self-care skill and sense of responsibility of the elderly patients with prostate cancer during the endocrine therapy, eventually improving the patient's ability in self care.
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.
ABSTRACT
Objective To evaluate the clinical safety and efficiency of applying 125I permanent-implant prostate brachytherapy (BRT) in elderly prostate cancer patient treatment.Methods From Jan.2007 to Dec.2011,23 elderly patients (age ≥75 years) with a diagnosis of localized prostate cancer were treated at our institution and then were evaluated retrospectively.The average age was 79.7 (ranged from 75-87) years.The average prostate volume was 52 (ranged from 35-78) ml.PSA level was 6.2±1.5 (ranged from 3.3 to 9.8) μg/L.Seven cases were in T1cN0M0,sixteen cases were in T2aN0M0.Five cases were with Gleason score of 4,two cases were with Gleason score of 5,sixteen cases were with Gleason score of 6.All patients received a single 125I permanent-implant brachytherapy with a total dosage of 145 Gy.Patients were stratified according to biochemical recurrence-free survival (bDFS),overall survival rate (OS) and complications.All the patients had not accepted anti-androgen therapy or external radiotherapy.Results The average followed up were 50 (ranged from 4 to 77) mon.After 3 months,the average serum PSA was 2.4±0.4(ranged from 0.9-3.8) μg/L,there was significant difference compared with that before treatment (P=0.003).After 1 years,the average serum PSA was 0.2-2.7 μg/L and 87％ (20/23) patient's PSA was less than 1 μg/L.2 cases had biochemical recurrence (bNED rate,91％).4 patients died,among them 1 patients died of prostate cancer.The overall survival rate was 83％,and the cancer-specific survival rate was 96％.Of the patients with urethral adverse effects,0-V adverse effect rates were 34.8％,43.5％,17.4％,4.3％,0 and 0.No serious complication such as rectal fistula occurred.Conclusions BRT is an effective and safe monotherapy in elderly prostate cancer patients.
ABSTRACT
Objective To evaluate the anestheisa efficacy of periprostatic nerve block in transrectal ultrasound (TRUS) guided biopsy of the prostate.Methods A total of 223 patients received prostate biopsy in our hospital from July 2010 to December 2013 were retrospectively studied,and were divided randomly into two groups.One hundred and sixteen cases in nerve block group accepted local anesthesia of prostate capsule and periprostatic nerve block after local perineal skin anesthetia,and 107 cases in local anesthesia group only accepted local perineal skin anesthetia and local anesthesia of prostate capsule.Patients in the 2 groups underwent prostate biopsy successfully.The visual analogue scale (VAS) and complications were recorded.Results The age,serum PSA level before biopsy,prostate volume and the number of puncture needles had no significant differences between the 2 groups (P＞0.05).The average VAS score was 2.3± 1.1,and 4.9±2.3 in the 2 groups.The VAS had significant difference between the 2 groups (P＜0.05).The incidences of hematuria,hemospermia and urinary retention were 37.1％ (43/116),3.4％ (4/116) and 1.7％ (2/116) in nerve block group,and 39.3％ (42/107),4.7％ (5/107) and 1.9％ (2/107) in local anesthesia group.The difference was not significant (P＞0.05).Conclusion Periprostatic nerve block for TRUS guided biopsy of the prostate could be safe with good analgesic effect.
ABSTRACT
Objective To assess the safety and efficiency of systematic transperineal ultrasound guided template positioning biopsy for the high-risk population of prostate cancer.Methods From January 2010 to January 2012 a total of 42 high-risk men of prostate cancer underwent systematic ultrasound guided biopsy using the transperineal template positioning technique.All patients got at least one previous biopsy,and all the patients showed negative results,including prostatic intraepithelial neoplasia,and/or atypical small cell acinar proliferation.During the follow-up,all the patients still had high prostate specific antigen (PSA) velocity (＞ 0.75 μg/L) or high PSA level (＞ 10 μg/L).Results A mean of 18.7 biopsy cores had been obtained.Cancer was identified in 19 of the 42 men (44％).The mean Gleason score was 6 (from 4 to 9).Mean prostate volume in the positive and negative biopsy groups was 44 and 71 ml.The only significant independent influence factor for positive biopsy was prostate volume (P ＜ 0.05).The positive rate showed no statistic difference in term of presence of PIN,AHH,the number of biopsy sites,or PSA value (P ＞0.05).Adenocarcinoma was found in transition zone in 14 of 19 cases (74％),and 5 (36％) was positive only in the transition zone.Complications were rare and self-limiting,including hematuria (29％)and urinary retention (0.9％).Conclusions Systematic transperineal template positioning biopsy of the prostate is a safe and precise biopsy technique in patients who remain at high-risk for prostate adenocarcinoma.
