Kim M, Yoo D, Pyo J, Cho W. Clinicopathological Significances of Positive Surgical Resection Margin after Radical Prostatectomy for Prostatic Cancers: A Meta-Analysis. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58091251. [PMID: 36143928 PMCID: PMC9500731 DOI: 10.3390/medicina58091251] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 08/12/2022] [Accepted: 08/26/2022] [Indexed: 12/24/2022]
Abstract
Background and Objectives: This study aims to elucidate the positive rate and the clinicopathological significance of surgical margin after radical prostatectomy (RP) through a meta-analysis. Materials and Methods: This meta-analysis finally used 59 studies, including the information about the positive surgical margin (PSM) and those clinicopathological significances after RP. The subgroup analysis for the estimated rates of PSM was evaluated based on types of surgery, grade groups, and pathological tumor (pT) stages. We compared the clinicopathological correlations between positive and negative surgical margins (NSM). Results: The estimated PSM rate was 25.3% after RP (95% confidence interval [CI] 21.9-29.0%). The PSM rates were 26.0% (95% CI 21.5-31.1%) 28.0% (95% CI 20.2-37.5%) in robot-assisted RP and nerve-sparing RP, respectively. The PSM rate was significantly higher in high-grade groups than in low-grade groups. In addition, the higher pT stage subgroup had a high PSM rate compared to the lower pT stage subgroups. Patients with PSM showed significantly high PSA levels, frequent lymphovascular invasion, lymph node metastasis, and extraprostatic extension. Biochemical recurrences (BCRs) were 28.5% (95% CI 21.4-36.9%) and 11.8% (95% CI 8.1-16.9%) in PSM and NSM subgroups, respectively. Patients with PSM showed worse BCR-free survival than those with NSM (hazard ratio 2.368, 95% CI 2.043-2.744%). Conclusions: Our results showed that PSM was significantly correlated with worse clinicopathological characteristics and biochemical recurrence-free survival. Among the results in preoperative evaluations, grade group and tumor stage are useful for the prediction of PSM.

Li H, Chang X, Du Y. Perineural invasion detected in prostate biopsy is a predictor of positive surgical margin of radical prostatectomy specimen: A meta-analysis. Andrologia 2022; 54:e14395. [PMID: 35233813 DOI: 10.1111/and.14395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Revised: 01/26/2022] [Accepted: 01/30/2022] [Indexed: 11/27/2022] Open
Abstract
The role of perineural invasion detected by puncture biopsy of prostate cancer remains controversial. We performed a meta-analysis to assess the relationship between positive perineural invasion at prostate biopsy and positive surgical margins (PSM) after radical prostatectomy. We searched a number of relevant electronic databases including Web of Science, Medline, PubMed, Embase, and the Cochrane Library until 31 March 2021. STATA 15.1 software was used to analyse all data for this article. The quality of these studies was assessed by the Newcastle-Ottawa Scale (ranged from 0 to 9 stars). Finally, we selected 13 high-quality studies in our meta-analysis, which contain 8283 patients. Overall pooled analysis proposed that biopsy perineural invasion was related to a higher risk of the positive surgical margins after radical prostatectomy in prostate cancer (RR: 1.73; 95% CI: 1.56-1.92; z = 10.30, p = 0.000). Moreover, the outcomes of the publication bias checkout testified that without significant bias arose (Egger's test: 0.086 > 0.05; Begg's test: 0.59 > 0.05). The existing evidence indicates that higher incidence of positive surgical margins in patients who had perineural invasion was detected in prostate biopsy.

Abstract
BACKGROUND Pre-operative staging of pancreatic adenocarcinoma guides clinical decision making. Limited data indicate that metastasis to celiac ganglia (CG) correlates with poor prognosis. We investigated feasibility and safety of endoscopic ultrasound fine needle aspiration (EUS-FNA) detection of CG metastasis and its impact upon tumor stage, resectability, and survival in pancreatic ductal adenocarcinoma (PDAC). PATIENTS We reviewed our prospectively maintained EUS and cytopathology databases to identify patients with FNA proven CG metastasis in patients with PDAC from 2004 to 2017. Clinical demographics, EUS, CT, MRI, cytopathology, cancer stage, and resectability data were analyzed. Survival of PDAC patients with CG metastasis was compared to the expected survival of PDAC patients of similar stage as reported by the United States National Cancer Database. RESULTS Twenty-one patients with PDAC [median age 73 (IQR63-78); 14 (67%) female)], had CG metastasis confirmed by cytopathologic assessment. CG metastasis resulted in tumor upstaging relative to other EUS findings and cross sectional imaging findings in 12 (57%) and 15 (71%) patients, and converted cancers from resectable to unresectable relative to EUS and cross sectional imaging in 7 (37%) and 7 (37%) patients, respectively. In patients with PDAC, the survival of patients with CG metastasis was not significantly different from the overall survival (hazard ratio 0.71; 95% confidence interval 0.44, 1.13; p = 0.15). CONCLUSIONS EUS-FNA may safely identify CG metastases. While CG metastasis upstaged and altered the resectability status among this cohort of patients with PDAC, the survival data with regard to PDAC suggest that this may be misguided.

Abstract
Objectives: To investigate the association between biopsy perineural invasion (PNI) and oncological outcomes of prostate cancer (PCa) after radical prostatectomy (RP).Materials and methods: A systematic literature search was performed using PubMed, EMBASE and Web of Science up to December 2018 to identify the eligible studies that included localized PCa patients who underwent biopsy and subsequently RP as well as follow-up information. Meta-analyses were conducted using available hazard ratios (HRs) of biopsy PNI from both univariate and multivariate analyses.Results: Eighteen studies including 14,855 patients with treatment follow-up information were included in the current systematic review. The rate of biopsy PNI varied between 7.0% and 33.0%. Seven out of the 18 studies that demonstrated biopsy PNI were associated with adverse pathologic features. Thirteen out of the 18 studies showed biopsy PNI correlated significantly with higher rates of biochemical recurrence (BCR)/cancer progression status or worse prognostic outcomes. With pooled data based on four studies with available univariate analysis results and four studies with multivariate analysis, statistically significant associations were found between biopsy PNI and BCR with univariate analysis (HR = 2.05; 95% CI = 1.57-2.68; p < 0.001) and with multivariate analysis (HR = 1.57; 95% CI = 1.28-1.93; p < 0.001).Conclusion: Evidence from the included observational studies indicated that biopsy PNI was not only correlated with adverse pathologic characteristics but also with worse BCR prognosis of local PCa after RP. The status of biopsy PNI could serve as a promising risk-stratification factor to help the decision-making process, considering active surveillance (AS) or further treatment for PCa patients.

Abstract
Background Prostate cancer is the second most common malignancy among men worldwide and the sixth cause of cancer-related death. Some authors have reported a relationship between perineural invasion (PNI), Gleason score, and the invasion of peripheral organs during prostatectomy. However, it is not yet clear whether pathological evidence of PNI is necessary for risk stratification in selecting treatment type. Objectives The clinical and pathological stages of prostate cancer are compared in patients under radical prostatectomy and in patients without perineural invasion. Patients and Methods This cross-sectional study was conducted using a sample of 109 patients who attended a tertiary health care center from 2008 to 2013. The selection criteria were PNI in prostate biopsy with Gleason scores less than six, seven, and eight to ten. The participants were enrolled in a census manner, and they underwent clinical staging. After radical prostatectomy, the rates of pathological staging were compared. The under-staging and over-staging rates among those with and without perineural invasion in biopsy samples were compared. Results The concordance between Gleason scores according to biopsy and pathology was 36.7% (40 subjects). The concordance rate was 46.4% and 33.3% among those with and without PNI, respectively. The concordance rates were significantly varied in different subclasses of Gleason scores in patients without PNI (P = 0.003); the highest concordance rate was a Gleason score of 7 (63.6%) and the lowest was a Gleason score of eight to ten (25%). However, there were no significant differences in patients with PNI (P > 0.05). Conclusions Although the presence of PNI in prostate biopsy is accompanied by higher surgical stages, PNI is not an appropriate independent factor in risk stratification.

Perineural invasion in prostate biopsy specimens is associated with increased bone metastasis in prostate cancer. Prostate 2015; 75:1783-9. [PMID: 26286637 DOI: 10.1002/pros.23067] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2015] [Accepted: 08/06/2015] [Indexed: 11/07/2022]
Abstract
BACKGROUND We aimed to evaluate the relationship between perineural invasion (PNI) and bone metastasis in prostate cancer (PCa). METHODS We retrospectively reviewed the data of 633 PCas who had whole-body bone scan (WBBS) between 2008 and 2014. We recorded the age, clinical T-stage, total PSA (tPSA) prior to biopsy, Gleason sum (GS), and PNI in transrectal ultrasound guided biopsy (TRUS-Bx) and digital rectal examination findings. Bone metastases were assessed with WBBS and magnetic resonance image if WBBS was suspicious. We divided the patients into two groups according to NCCN criteria: (Group 1) bone scan not indicated, (Group 2) bone scan indicated. RESULTS There were 262 patients in Group 1 and 371 in 2. There is not significant relationship between PNI and bone metastasis in Group 1. However, there is very limited number of metastatic patients (n = 12) in this group. There is a strong relationship between PNI and bone metastasis in Group 2 (P = 0.001). Sensitivity, specificity and positive predictive value of PNI for bone metastasis were 72.4%, 81.7%, and 77.7%, respectively. In this group, tPSA, GS, positive DRE, and PNI were significant covariates for prediction of bone metastasis in univariate and multivariate analysis (except age). The most powerful predictor was PNI, and it increased the risk of bone metastasis 11-fold. CONCLUSIONS PNI in the TRUS-Bx specimens is the most powerful predictive histopathological feature for bone metastasis, by increasing the risk of bone metastasis 11-fold in NCCN bone scan indicated patients (Group 2).

Abstract
Perineural invasion is a symbiotic relationship between cancer cells and nerves and is most frequently seen in "neurotropic" cancers such as prostate cancer. It results in increased perineural space cancer cell growth and decreased apoptosis and induces nerve growth. Tissue microarrays were constructed from 640 radical prostatectomy specimens with prostate cancer. The perineural diameter was measured as previously described. Multiple biomarkers have been previously performed on this tissue microarray cohort, and all data were kept in the same database. The biomarker results database was queried for correlations between perineural invasion diameter and tissue biomarkers. Increased perineural invasion diameter correlated with increased proliferation of prostate cancer cells and with apoptosis. It also correlated with proteins involved in survival pathways such as nuclear factor κB, c-Myc, phosphorylated AKT, and its downstream effector FHKR, but not with GSK. Unlike nerve density, it did not correlate with decreased PTEN expression. Increased perineural invasion diameter was associated with higher levels of hormonal receptors such as androgen receptor, but not estrogen receptor. Also associated with perineural invasion diameter were coregulators and corepressors including SRC1 and TIF2. Perineural invasion diameter had the strongest correlation with tumor volume (ρ = 0.579, P = .000), not identified with nerve density. These data demonstrate that perineural invasion has the same biologic correlations as neural density. However, we found a distinct and very strong correlation with increased tumor volume. These data confirm that perineural invasion is the ultimate and most successful interaction between cancer cells and nerve fibers, resulting in increased tumor growth.

Abstract
A systematic review of the literature was performed to assess the relationship between the presence of perineural invasion (PNI) at prostate biopsy and extraprostatic extension (EPE) of prostate cancer. In August 2012, Medline, Embase, Scopus and Web of Science databases were searched. A "free-text" protocol using the terms "perineural invasion prostate cancer" was applied. Studies published only as abstracts and reports from meetings were not included in this review. In total, 341 records were retrieved from Medline, 507 from Embase, 374 from Scopus and 65 from the Web of Science database. The records were reviewed to identify studies correlating the presence of PNI with that of EPE. A cumulative analysis was conducted using Review Manager software v. 5.1 (Cochrane Collaboration, Oxford, UK). In univariate analysis, PNI showed a statistically significant association with pT3 tumours (p < 0.00001), which could be observed for both pT3a (p < 0.0001) and pT3b (p < 0.0001). In conclusion, the cumulative analysis shows a statistically significant higher incidence of EPE in patients who had PNI at needle biopsy. The main limitation of the analysis was that it was not possible to perform a multivariate analysis. Further attempts to build a nomogram for the prediction of EPE could include the presence of PNI at needle biopsy.

Abstract
BACKGROUND The objective is to provide surgical and pathological guidelines for radical prostatectomy (RP) with or without concurrent pelvic lymph node dissection (PLND) to achieve optimal benefit for patients, with minimal risk of harm. METHODS For surgical questions, a literature search of MEDLINE, EMBASE and the Cochrane database was performed. A literature search for the pathological questions was not conducted since the protocol for invasive carcinomas of the prostate gland developed by the College of American Pathologists (CAP) was endorsed. Urologists and pathologists were consulted for their assessment of the surgical and pathological recommendations. RESULTS Limited high-quality evidence from 95 primary studies was available and, therefore, the expert panel developed recommendations on the basis of a consensus of the expert opinion of the working group and through a consultation with urologists and pathologists. In addition to the CAP protocol, some technical recommendations related to the handling and processing of the specimen were made. CONCLUSION Radical prostatectomy is recommended for the surgical treatment of prostate cancer, depending on a patient's preoperative risk profile. The panel unanimously determined that the goals for RP are to attain a positive margin rate of <25% for pT2 disease, a mortality rate of <1%, rates of rectal injury of <1% and blood transfusion rates of <10% in non-anemic patients. Standard PLND should be mandatory in high-risk patients, should be recommended for intermediate-risk patients and should be optional for low-risk patients. The quality and effectiveness of this treatment and of subsequent patient care depend on good management, effective communication and reporting between surgeons and pathologists working together as part of a multidisciplinary team. The complete guideline document is posted on the Cancer Care Ontario website (www.cancercare.on.ca); search in their Toolbox, Quality Guidelines & Standards, Clinical Program category under "surgery."

Abstract
INTRODUCTION Despite tumour cell dissemination through the intraprostatic nervous system being considered as a prostate cancer progression mechanism, the significance of perineural invasion in prostate biopsies to predict extraprostatic extension and its use as a potential prognosis factor is controversial. MATERIALS AND METHODS Retrospective study carried out at an institution on 208 patients treated with radical prostatectomy (January 2007 - July 2010) in which the presence of perineural invasion and the Gleason score in the preoperative biopsy were determined, as well as the clinical stage and the pre-surgery PSA. We classified the patients in risk groups in accordance with the D'Amico classification. We performed bivariate and multivariate statistical analyses to establish the correlations between the different variables. RESULTS We objectified PNI in 18.3% of the prostate biopsies. 71% of the prostatectomy specimens with perineural invasion presented extraprostatic extension in the previous biopsy against 23.1% when this was not found (p<0.0001) and 47% of the cases showed positive margins with PNI, against 18.3% without perineural invasion (p<0.0001). In fact, in the multivariate analysis, perineural invasion proved to be an independent risk factor in the presentation of extraprostatic extension and positive margins in the prostatectomy specimen. CONCLUSIONS The presence of perineural invasion is a useful prognostic factor for predicting extraprostatic extension and the involvement of surgical margin in the radical prostatectomy specimen. We believe that determining it may be a useful tool for improving preoperative diagnosis and planning treatment.

Abstract
PURPOSE Perineural invasion (PNI) in prostate biopsies is associated with increased risk of higher Gleason score and worse pathologic stage. We report the influence of PNI in biochemical no evidence of disease (bNED) survival after (125)I prostate brachytherapy (BT). METHODS AND MATERIALS Pathology reports of 700 men with localized prostate cancer who underwent (125)I prostate BT in 1999-2008 were reviewed. The presence or absence of PNI in the biopsy was documented in 339 men. Clinical, treatment, and dosimetric parameters, along with PNI status, were evaluated for bNED survival, defined by "nadir+2" definition. RESULTS Of the 339 patients, 87% had favorable risk and 13% intermediate risk. PNI was present in 89 patients (26%). After a median followup of 32 months, there were five biochemical failures (4: +PNI and 1: -PNI), of which one was local failure (+PNI). Actuarial 5-year bNED survival for the entire group was 97.0% (92.9% for +PNI; 99.2% for -PNI). In univariate analysis age, pretreatment prostate-specific antigen, Gleason score 7, and intermediate risk group predicted for worse biochemical outcome, whereas the presence of PNI showed a trend toward significance (p=0.06). Some of the regression algorithms failed to converge because of low event rates. CONCLUSIONS We report excellent biochemical control in 339 men treated with (125)I prostate BT. The presence of PNI showed a trend toward significance in predicting 5-year bNED survival but did not impact on local control and should not influence the decision to recommend BT for localized prostate cancer.

Abstract
The prognostic significance of perineural invasion by prostate cancer is debated. We have evaluated the association between biochemical failure and measurements of perineural invasion in radical prostatectomy specimens. Perineural invasion was identified in sections using S-100 protein immunostaining. For nerves showing invasion, the involved nerve closest to the edge of the prostate and to the surgical excision margin, as well as the diameter of these nerves, the largest nerve showing perineural invasion and its proximity to the excision margin, and the percentage of nerves showing perineural invasion up to 1.75 mm from the excision margin was determined and tested against time to prostate-specific antigen failure, along with preoperative prostate-specific antigen levels, highest Gleason primary grade, Gleason score and TNM T category. Perineural invasion was present in 90% of cases, with extraprostatic perineural invasion in 25% of tumors. Diameter of nerves showing perineural invasion ranged from 11 to 680 microm and the shortest distance to the surgical excision margin ranged from 33 to 2.57 mm. Perineural invasion density ranged from 6 to 96%. Gleason scores were six in 58 cases, seven in 43 cases, eight in three cases and nine in one case. Clinical T categories were T1c in 75 cases, T2a in 22 cases, T2b in five cases, T2c in two cases, T3 in one case. During a follow-up period of 11 to 55 months (median 26 months), 27 patients showed prostate-specific antigen failure. On univariate analysis only presence of extraprostatic perineural invasion, among parameters of perineural invasion, showed a weak correlation with outcome, while on multivariate analysis this lost significance and preoperative prostate-specific antigen levels, Gleason score and excision margin status were independently associated with biochemical failure. We conclude that the investigated parameters of perineural invasion do not predict prostate-specific antigen recurrence in radical prostatectomy specimens.

Abstract
The presence of positive surgical margins on radical prostatectomy specimen is an adverse prognostic factor. Parameters supposed to influence surgical margin status includes pathology method analysis, surgical technique, tumoral and non tumoral patient parameters, and neoadjuvant hormonal therapy. Regarding the surgical technique, surgeon's experience and neuro-vascular bundles preservation are the most important factors of margin status, whereas surgical approach, bladder neck conservation, intraoperative frozen analysis, and bleeding are minor factors. Non tumoural patient parameters influencing surgical margin status include patient's age and weight, and prostate gland weight. For tumoural parameters, pathological stage and tumour volume are more important factors than the tumor grade and PSA. Five preoperative tumoral risk factors of positive surgical margins are particularly important, including abnormal digital rectal examination, preoperative PSA 10 ng/mL, biopsy Gleason score >7, number of positive biopsy cores > or = 2, and suspicion of extraprostatic extension on radical prostatectomy specimen.

Perineural invasion associated with increased cancer-specific mortality after external beam radiation therapy for men with low- and intermediate-risk prostate cancer. Int J Radiat Oncol Biol Phys 2006; 66:403-7. [PMID: 16765530 DOI: 10.1016/j.ijrobp.2006.03.033] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2005] [Revised: 03/30/2006] [Accepted: 03/31/2006] [Indexed: 10/24/2022]
Abstract
PURPOSE To identify an association between perineural invasion (PNI) and cancer-specific survival in patients with prostate cancer after standard-dose external beam radiation therapy (RT). METHODS AND MATERIALS A total of 517 consecutive patients who underwent RT (median dose, 70.5 Gy) between 1989 and 2003 for low-risk or intermediate-risk prostate cancer were studied. A genitourinary pathologist (AAR) scored presence or absence of PNI on all prostate needle-biopsy specimens. A Cox regression multivariable analysis was performed to assess whether the presence of PNI was associated with risk of prostate cancer-specific mortality after RT when the recognized risk-group variables were factored into the model. Estimates of cancer-specific mortality were made using a cumulative incidence method. Comparisons of survival were made using a two-tailed log-rank test. RESULTS At a median follow-up of 4.5 years, 84 patients (16%) have died, 15 of 84 (18%) from prostate cancer. PNI was the only significant predictor of prostate cancer-specific mortality after RT (p=0.012). The estimated prostate cancer-specific mortality was 14% at 8 years for PNI+ patients vs. 5% for PNI- patients (p=0.0008). CONCLUSIONS Patients with low- or intermediate-risk prostate cancer who have PNI on prostate needle biopsy have a significantly higher rate of prostate cancer-specific mortality after standard-dose radiation therapy than patients without PNI. Although this analysis is retrospective, this association argues for consideration of the use of more aggressive therapy, such as hormonal therapy with RT or dose escalation, in these select patients.

Abstract
PURPOSE To determine if the presence of perineural invasion (PNI) predicts biochemical recurrence in patients who underwent low-dose-rate brachytherapy for the treatment of localized prostate cancer. METHODS AND MATERIALS A retrospective case control matching study was performed. The records of 651 patients treated with brachytherapy between 1996 and 2003 were reviewed. Sixty-three of these patients developed biochemical failure. These sixty-three patients were then matched in a one-to-one ratio to patients without biochemical failure, controlling for biopsy Gleason score, clinical stage, initial prostate-specific antigen, age, and the use of androgen deprivation. The pathology of the entire cohort was then reviewed for evidence of perineural invasion on initial prostate biopsy specimens. The biochemical relapse free survival rates for these two groups were compared. RESULTS Cases and controls were well matched, and there were no significant differences between the two groups in age, Gleason grade, clinical stage, initial prostate-specific antigen, and the use of androgen deprivation. PNI was found in 19 (17%) patients. There was no significant difference in the rates of PNI between cases and controls, 19.6% and 14.3% respectively (p = 0.45). PNI did not correlate with biochemical relapse free survival (p = 0.40). CONCLUSION Perineural invasion is not a significant predictor of biochemical recurrence in patients undergoing brachytherapy for prostate cancer.
