Abstract
Background and objectivesThe extent and survival benefits of lymph node dissection (LND) in radical prostatectomy (RP) for pN1M0 prostate cancer (PCa) patients remained unclear and were controversial. This study aimed to determine the survival benefit of different lymph node yields in RP for pN1M0 PCa patients.MethodspN1M0 PCa patients who received RP and LND were identified in Surveillance Epidemiology and End Results (SEER) (2010–2015). Patients were divided into two groups in SEER based on the removal of one to three regional lymph nodes (LND1 group) or four or more regional lymph nodes (LND4 group). Kaplan–Meier methods were used to calculate cancer-specific survival (CSS) and overall survival (OS).ResultsIn total, 2,200 patients were identified; 264 patients received LND1 and 1,936 patients received LND4. CSS had no significant difference between the LND4 and LND1 groups (101mon vs. 98mon, p = 0.064), and OS was higher in LND4 patients compared with LND1 patients (97mon vs. 93mon, p = 0.024); for patients with Gleason score = 9 or 10 and T3b or T4, 5-year OS was higher in patients undergoing LND4 (80.9%; 95% CI, 79.0–82.8) compared with those undergoing LND1 (67.5%; 95% CI, 60.8–74.2) (p = 0.009).ConclusionMore lymph node yield provided better survival for patients with Gleason score = 9 or 10 and T3b or T4, but not for other pN1M0 PCa patients. The extent of LND would be determined after a comprehensive evaluation including Gleason score, tumor stage, and the general condition of the patient.

[PMID: 35246070 PMCID: PMC8896158 DOI: 10.1186/s12885-022-09331-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Accepted: 02/24/2022] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Biochemical recurrence (BCR) after initial treatment, such as radical prostatectomy, is the most frequently adopted prognostic factor for patients who suffer from prostate cancer (PCa). In this study, we aimed to construct a prognostic model consisting of gene expression profiles to predict BCR-free survival. METHODS We analyzed 70 metabolic pathways in 152 normal prostate samples and 494 PCa samples from the UCSC Xena dataset (training set) via gene set enrichment analysis (GSEA) to select BCR-related genes and constructed a BCR-related gene risk score (RS) model. We tested the power of our model using Kaplan-Meier (K-M) plots and receiver operator characteristic (ROC) curves. We performed univariate and multivariate analyses of RS using other clinicopathological features and established a nomogram model, which has stronger prediction ability. We used GSE70770 and DFKZ 2018 datasets to validate the results. Finally, we performed differential expression and quantitative real-time polymerase chain reaction analyses of the UCSC data for further verification of the findings. RESULTS A total of 194 core enriched genes were obtained through GSEA, among which 16 BCR-related genes were selected and a three-gene RS model based on the expression levels of CA14, LRAT, and MGAT5B was constructed. The outcomes of the K-M plots and ROC curves verified the accuracy of the RS model. We identified the Gleason score, pathologic T stage, and RS model as independent predictors through univariate and multivariate Cox analyses and constructed a nomogram model that presented better predictability than the RS model. The outcomes of the validation set were consistent with those of the training set. Finally, the results of differential expression analyses support the effectiveness of our model. CONCLUSION We constructed an RS model based on metabolic genes that could predict the prognosis of PCa patients. The model can be easily used in clinical applications and provide important insights into future research on the underlying mechanism of PCa.

Abstract
Clinically node-positive prostate cancer is often found at the time of diagnosis by cross-sectional imaging and remains poorly understood. Advanced imaging modalities such as magnetic resonance imaging nanoparticles or positron emission tomography-based molecular imaging stand to rapidly change the field and hopefully will bring better diagnostic clarity. This will allow for prospective clinical trials using radiographic, clinical, or molecular parameters to establish who may benefit from both localized and systemic treatment intensification and who may avoid overtreatment. Recent advances in metastatic hormone-sensitive disease may offer clues, but direct studies for nodal disease patients remain.

Abstract
OBJECTIVES To evaluate whether indocyanine green guidance can improve the quality of extended pelvic lymph node dissection in patients undergoing radical prostatectomy. METHODS A total of 214 patients underwent laparoscopic radical prostatectomy with indocyanine green-guided lymph node dissection plus extended pelvic lymph node dissection. These patients (group A) were matched 1:1 for clinical risk groups according to the National Comprehensive Cancer Network classification with patients who underwent the same procedure without fluorescence guidance (group B). Biochemical recurrence was defined as two consecutive prostate-specific antigen rises of at least 0.2 ng/mL. The Kaplan-Meier method and Cox regression models were used to identify predictors of biochemical recurrence. RESULTS The median number of retrieved nodes was significantly higher in group A (22 vs 14, P < 0.001). The rate of lymph node metastases was higher in group A (65.9% vs 34.1%, P = 0.01). Increasing the yield of lymph node dissection was independently and negatively correlated with the biochemical recurrence risk in both overall and pN-positive patients (hazard ratio 0.97, P = 0.03; and hazard ratio 0.95, P = 0.02). The 5-year biochemical recurrence-free survival rates were (75.8% vs 65.9, P = 0.09) and (54.1% vs 24.9%, P = 0.023) for group A and group B in the overall cohort and pN-positive cohort, respectively. CONCLUSION Indocyanine green-guided lymph node dissection plus extended pelvic lymph node dissection improves identification of lymphatic drainage, resulting in a higher number of lymph nodes and retrieved lymph node metastases, and allowing a more accurate local staging and a prolonged biochemical recurrence-free survival.

Management of Patients with Node-positive Prostate Cancer at Radical Prostatectomy and Pelvic Lymph Node Dissection: A Systematic Review. Eur Urol Oncol 2020; 3:565-581. [PMID: 32933887 DOI: 10.1016/j.euo.2020.08.005] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 07/07/2020] [Accepted: 08/11/2020] [Indexed: 12/16/2022]
Abstract
CONTEXT Optimal management of prostate cancer (PCa) patients with lymph node invasion at radical prostatectomy and pelvic lymph node dissection still remains unclear. OBJECTIVE To assess the effectiveness of postoperative treatment strategies for pathologically node-positive PCa patients. The secondary aim was to identify the most relevant prognostic factors to guide the management of pN1 patients. EVIDENCE ACQUISITION A systematic review was performed in January 2020 using Medline, Embase, and other databases. A total of 5063 articles were screened, and 26 studies including 12 537 men were selected for data synthesis and included in the current review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) recommendations. EVIDENCE SYNTHESIS Ten-year biochemical recurrence (BCR)-free, clinical recurrence-free, cancer-specific (CSS), and overall (OS) survival rates ranged from 28% to 56%, 70% to 92%, 72% to 98%, and 60% to 87.6%, respectively. A total of seven, five, and six studies assessed the oncological outcomes of observation, adjuvant radiotherapy (aRT), or adjuvant androgen deprivation therapy (ADT), respectively. Initial observation followed by salvage therapies at the time of recurrence represents a safe option in selected patients with a low disease burden. The use of aRT with or without ADT might improve survival in men with locally advanced disease and a higher number of positive nodes. Risk stratification according to pathological Gleason score, number of positive nodes, pathological stage, and surgical margins status is the key to risk stratification and selection of the optimal postoperative therapy. Limitations of this systematic review are the retrospective design of the studies included and the lack of data on adverse events. CONCLUSIONS While the majority of men with pN1 disease would experience BCR after surgery, long-term disease-free survival has been reported in selected patients. Management options to improve oncological outcomes include observation versus adjuvant therapies such as aRT and/or ADT. Disease characteristics should be used to select the optimal postoperative management for pN1 PCa patients. PATIENT SUMMARY Finding node-positive prostate cancer after a radical prostatectomy often leads to high postoperative prostate-specific antigen levels and is overall a poor prognostic factor. However, this does not necessarily translate into poor survival for all men. Management can be tailored to the severity of disease and options include observation, androgen deprivation therapy, and/or radiotherapy.

Abstract
BACKGROUND The value of pelvic lymphadenectomy during radical prostatectomy (RP) remains controversial. This study aims to test the effects of the number of removed lymph nodes (RLN), positive nodes (pLN), and pLN ratio (pLNR) on cancer-specific survival (CSS) in patients with node-positive prostate cancer (PCa). METHODS A total of 2458 patients with a greater than 5% probability of lymph node invasion according to the updated Briganti nomogram who harboured pathologically confirmed positive nodes in the Surveillance, Epidemiology, and End Results database between 2004 and 2015 were identified. Multivariable Cox regression with forward stepwise selection was performed to identify independent risk factors for CSS. Maximally selected rank statistics were used to determine the most informative cut-off value for pLN and pLNR. RESULTS The median pLN counts and RLN in the study were two (interquartile range [IQR] 1- 3) and 18 (IQR 15-23), respectively. The RLN counts could not predict CSS, while the higher pLN and pLNR were associated with worse CSS (hazard ratio [HR], 1.11; p < 0.001 and HR, 1.01; p < 0.001, respectively). Patients with ≤ 2 pLN or pLNR ≤ 20% had significantly better CSS than those with pLN > 2 or pLNR > 20% (HR, 1.38 (1.08-1.77); p = 0.009; HR, 1.77 (1.41-2.22); p < 0.001, respectively). CONCLUSIONS In patients with node-positive PCa, pelvic lymphadenectomy provides important information for staging, prognosis, and guiding after RP therapy; however, it does not play a therapeutic role. The pLN counts and pLNR were independent predictors of CSS.

Abstract
Background Some historic breakthroughs have been made in immunotherapy of advanced cancer. However, there is still little research on immunotherapy in prostate cancer. We explored the relationship between immune cell infiltration and prostate cancer recurrence and tried to provide new ideas for the treatment of prostate cancer. Methods Prostate cancer RNA-seq data and clinical information were downloaded from the TCGA database and GEO database. The infiltration of 24 immune cells in tissues was quantified by ssGSEA. Univariate Cox regression analysis was used to screen for immune cell types associated with tumor recurrence, weighted gene co-expression network analysis (WGCNA) and LASSO were used to identify hub genes which regulate prognosis in patients through immune infiltration. Then, the nomogram was constructed based on the hub gene to predict the recurrence of prostate cancer, and the decision curve analysis (DCA) was used to compare the accuracy with the PSA and Gleason prediction models. Result Analysis showed that Th2 cells and Tcm related to prostate cancer recurrence after radical prostatectomy, and they are independent protective factors for recurrence. Through WGCNA and Lasso, we identified that NDUFA13, UQCR11, and USP34 involved in the infiltration of Th2 cells and Tcm in tumor tissues, and the expression of genes is related to the recurrence of patients. Based on the above findings, we constructed a clinical prediction model and mapped a nomogram, which has better sensitivity and specificity for prostate cancer recurrence prediction, and performed better in comparison with PSA and Gleason’s predictions. Conclusion The immune cells Th2 cells and Tcm are associated with recurrence of PCa. Moreover, the genes NDUFA13, UQCR11, and USP34 may affect the recurrence of PCa by affecting the infiltration of Th2 cells and Tcm. Moreover, nomogram can make prediction effectively.

Abstract
PURPOSE To demonstrate the benefits of fluorescence-supported extended pelvic lymph node dissection (ePLND) compared to regular ePLND in robot-assisted radical prostatectomy. METHODS 120 patients with intermediate- or high-risk prostate cancer were prospectively randomized (1:1): in the intervention group, indocyanine green (ICG) was injected transrectally into the prostate before docking of the robot. In both groups, ePLND was performed including additional dissection of fluorescent lymph nodes (LN) in the ICG group. RESULTS After drop-out of two patients, 59 patients were allocated to the control (A) and intervention group (B) with a median PSA of 8,6 ng/ml. Median console time was 159 (A) vs. 168 (B) min (p = 0.20) with a longer time for ICG-ePLND: 43 (A) vs. 55 min (B) (p = 0.001). 2609 LN were found with significantly more LN after ICG-supported ePLND with a median of 25 vs. 17 LN in A (p < 0.001). Nodal metastases were detected in 6 patients in A (25 cancerous LN) vs. 9 patients in B (62 positive LN) (p = 0.40). In seven of nine patients, ICG-ePLND identified at least one cancer-positive LN (sensitivity 78%), 27 of 62 cancerous LN were fluorescent. Symptomatic lymphocele occurred in one patient in a and in three patients in b (p = 0.62). After a median follow-up of 22.9 months, PSA levels were similar. CONCLUSIONS While ICG-ePLND seems to be beneficial for a better understanding of the lymphatic drainage and a more meticulous diagnostic approach, the sensitivity is not sufficient to recommend stand-alone ICG lymph node dissection.
