Abstract
OBJECTIVES To investigate whether patients with suspected pelvic lymph node metastases (molecular imaging [mi] N1) on staging prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) had a different oncological outcome compared to those in whom the PSMA PET/CT did not reveal any pelvic lymph node metastases (miN0). PATIENTS AND METHODS All patients with pelvic lymph node metastatic (pN1) disease after robot-assisted radical prostatectomy (RARP) and extended pelvic lymph node dissection (ePLND) between January 2017 and December 2020 were included. To assess predictors of biochemical progression of disease after RARP, a multivariable Cox regression analysis was performed, including number of tumour-positive lymph nodes, diameter of the largest nodal metastasis, and extranodal extension. RESULTS In total, 145 patients were diagnosed with pN1 disease after ePLND. The median biochemical progression-free survival in patients with miN0 on PSMA PET/CT was 13.7 months, compared to 7.9 months in patients with miN1 disease (P = 0.006). On multivariable Cox regression analysis, both number of tumour-positive lymph nodes (>2 vs 1-2: hazard ratio [HR] 1.97; P = 0.005) and diameter of the largest nodal metastasis (HR 1.12; P < 0.001) were significant independent predictors of biochemical progression of disease. CONCLUSION Patients in whom pelvic lymph node metastases were suspected on preoperative PSMA imaging (miN1), patients diagnosed with >2 tumour-positive lymph nodes, and patients with a larger diameter of the largest nodal metastasis had a significantly increased risk of biochemical disease progression after surgery.

Oncologic outcomes of patients with lymph node invasion at prostatectomy and post-prostatectomy biochemical persistence. Urol Oncol 2023; 41:105.e19-105.e23. [PMID: 36435708 PMCID: PMC10391319 DOI: 10.1016/j.urolonc.2022.10.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 08/30/2022] [Accepted: 10/20/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND Pathologic nodal invasion at prostatectomy is frequently associated with persistently elevated prostate-specific antigen (PSA) and with increased risk of disease recurrence. Management strategies for these patients are poorly defined. We aimed to explore the long-term oncologic outcomes and patterns of disease progression. METHODS We included men treated between 2000 and 2017 who had lymph node invasion at radical prostatectomy and persistently detectable prostate-specific antigen post-prostatectomy. Postoperative imaging and management strategies were collated. Patterns of recurrence and probability of metastasis-free survival, prostate cancer-specific survival, and overall survival (OS) were assessed. RESULTS Among our cohort of 253 patients, 126 developed metastasis. Twenty-five had a positive scan within 6 months of surgery; of these, 15 (60%) had a nodal metastasis, 10 (40%) had a bone metastasis, and 4 (16%) had local recurrence. For metastasis-free survival, 5- and 10-year probabilities were 52% (95% CI 45%, 58%) and 37% (95% CI 28%, 46%), respectively. For prostate cancer-specific survival, 5- and 10-year probabilities were 89% (95% CI 84%, 93%) and 67% (95% CI 57%, 76%), respectively. A total of 221 patients proceeded to hormonal deprivation treatment alone. Ten patients received postoperative radiotherapy. CONCLUSIONS Biochemical persistence in patients with lymph node invasion is associated with high risk of disease progression and reduced prostate cancer-specific survival. Management was hindered by the limitation of imaging modalities utilized during the study period in accurately detecting residual disease. Novel molecular imaging may improve staging and help design a therapeutic strategy adapted to patients' specific needs.

Early results of PRO-EPI: PROspective multicenter observational study on elective pelvic nodes irradiation in patients with intermediate/high/very high-risk non-metastatic prostate cancer submitted to radical, adjuvant, or salvage radiotherapy with or without concomitant androgen deprivation therapy. Front Oncol 2022; 12:951220. [PMID: 36408148 PMCID: PMC9666761 DOI: 10.3389/fonc.2022.951220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 09/29/2022] [Indexed: 11/30/2022] Open
Abstract
Simple Summary: Although radiotherapy plays a fundamental role in the management of intermediate/high/very high-risk non-metastatic prostatic cancer (IHR-nmPca), there is still no consensus on the optimal treatment strategy in this setting. Remarkably, the role of elective nodal irradiation (ENI) is still highly controversial. The PROspective multicenter observational study on Elective Pelvic nodes Irradiation (PRO-EPI) was designed to provide "real life" data regarding the patterns of care for IHR-nmPca. Forty-three Italian Radiation Oncology centers participated in the PROspective multicenter observational study on Elective Pelvic nodes Irradiation (PRO-EPI) project, with 1029 patients enrolled. In this preliminary analysis, we longitudinally evaluated the impact of Elective Nodal Irradiation (ENI) and radiotherapy features on toxicity and quality of life (QoL). Six months follow-up data were available for 913 patients and 12 months data for 762 patients. Elective Nodal Irradiation was given to 506 patients (48.9%). Volumetric Intensity-Modulated Radiation Therapy (IMRT) was adopted in more than 77% of patients and Image-Guided Radiation Therapy (IGRT) in 84.4%. Androgen deprivation therapy (ADT) was administered to the majority of patients (68.3%), and it was associated to ENI in 408 cases (81.1%). Toxicity was mostly mild and reversible and IGRT resulted in a significant reduction of rectal toxicity, although a non-significant trend toward increased urinary toxicity was observed. No statistically significant differences in QoL and toxicity were seen in patients treated with or without ENI. The adoption of IGRT is widespread and increasing and could reduce treatment toxicity. ENI is not yet the standard treatment, but it is performed in a growing fraction of cases and not resulting into an increase in toxicity or in a deterioration of QoL. Further analyses are needed to clarify the long-term toxicity profile and the impact of ENI on survival.

Prostate Cancer Prostatic Dis 2022:10.1038/s41391-022-00508-7. [PMID: 35169274 DOI: 10.1038/s41391-022-00508-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 01/18/2022] [Accepted: 02/01/2022] [Indexed: 11/09/2022]
Abstract
Socioeconomic status (SES), race and geographical factors are known to impact prostate cancer management and outcomes. We aimed to assess these factors with regard to access to novel imaging in prostate cancer. Using the Prostate Cancer Outcomes Registry of Victoria (PCOR-Vic) we identified 5256 men diagnosed with prostate cancer via biopsy. Following the introduction of government rebate, the access to MRI improved with respect to SES. Access to PET imaging remains poor with respect to SES and geographical location in the absence of Federal funding. Further improvements for men with low SES and regional areas to access PET staging.
