Biochemical Recurrence Articles

The role of 18F-fluorocholine positron emission tomography/computed tomography (18F-Choline PET/CT) in different clinical situations remains controversial and current practices are very heterogeneous.

To evaluate the diagnostic performance of [(68)Ga]Ga-PSMA(HBED-CC) conjugate 11 positron emission tomography (PSMA-PET) in the early detection of metastases in patients with biochemical recurrence (BCR) after radical prostatectomy (RP) for clinically non-metastatic prostate cancer, to compare it to CT/MRI alone and to assess its impact on further therapeutic decisions.

(68)Ga prostate specific membrane antigen (PSMA) positron emission tomography (PET)/computer tomography (CT) is a new method to detect early nodal metastases in patients with biochemical relapse of prostate cancer (PCa).

Localization of prostate cancer recurrence, particularly in the bones, is a major challenge with standard of care imaging in patients with biochemical recurrence following curatively intended treatment.

Aim: To assess the impact of (68)Ga-Prostate Specific Membrane Antigen (PSMA) Positron Emission Tomography/ Computed Tomography (PET/CT) on management of prostate cancer in patients with biochemical recurrence (BCR).

BACKGROUND - [-2]proPSA and its derivatives have an higher diagnostic accuracy than PSA in predicting prostate cancer (PCa). In alternative to PSA, ultrasensitive PSA (uPSA) and [-2]proPSA could be potentially useful in recurrent disease detection.

The influence of the delay between prostate biopsy and radical prostatectomy for patients with localized prostate cancer is controversial. The objective of this study was to establish a time limit between prostate biopsy and radical prostatectomy beyond which the risks of upgradging and biochemical recurrence (BCR) are increased.

Phosphodiesterase type 5 (PDE-5) inhibitors are widely used for penile rehabilitation and treatment of erectile dysfunction after radical prostatectomy. Recently, Michl et al. showed in a monocentric, retrospective and non-randomized analysis that PDE-5 inhibitors may cause higher biochemical recurrence rates after radical prostatectomy.

To identify markers for predicting aggressive forms of prostate cancer.

The study retrospectively evaluated expression of angiotensin II type 2 receptors (AT2-R) in prostate needle biopsy tissue from patients with and without biochemical recurrence after combined hormone and radiation therapy.

18F-labelled prostate-specific membrane antigen (PSMA) positron emission tomography (PET) tracers are increasingly used in preference to 68Ga-PSMA-11 for restaging biochemical recurrence (BCR) of prostate cancer.

We aimed to report on multiparametric MRI (mpMRI) characteristics of post-primary focal cryosurgery (PFC) patients suspected of biochemical recurrence (BCR) by the Phoenix criteria.

We retrospectively reviewed all patients at our institution who had undergone PFC.

68Ga-labelled prostate specific membrane antigen (PSMA) ligand PET/CT is a promising modality in primary staging (PS) and biochemical relapse (BCR) of prostate cancer (PC). However, pelvic nodes or local recurrences can be difficult to differentiate from radioactive urine.

The early and accurate detection of prostate cancer is important to ensure timely management and appropriate individualized treatment. Currently, conventional imaging has limitations particularly in the early detection of metastases and at prostate-specific antigen (PSA) levels < 2.

The aim of this study was to prospectively compare the detection rate of 68Ga-PSMA versus 11C-Choline in men with prostate cancer with biochemical recurrence and to demonstrate the added value of a tri-modality PET/CT-MRI system.

The primary aim of this retrospective, single-centre analysis was to assess the performance of 68Ga-PSMA-11 PET/CT in prostate cancer (PCa) patients in early PSA failure after radical prostatectomy (RP).

To test the agreement between high-grade PCa at RP and TMA, and the ability of TMA to predict BCR. Validation of concordance between tissue microarray (TMA) and radical prostatectomy (RP) high-grade prostate cancer (PCa) is crucial because latter determines the treated natural history of PCa.

Within five to ten years after radical prostatectomy (RP), approximately 15-34% of prostate cancer (PCa) patients experience biochemical recurrence (BCR), which is defined as recurrence of serum levels of prostate-specific antigen >0.

18F-DCFPyL, a prostate specific membrane antigen targeting radiotracer, has shown promise as a prostate cancer imaging radiotracer. We evaluated the safety, sensitivity and impact on patient management of 18F-DCFPyL in the settings of biochemical recurrence of prostate cancer.

In patients treated for prostate cancer, a rising serum prostate-specific antigen (PSA) level is a first sign of relapse, but imaging is needed to determine the localization of the recurrence, which may be local, in lymph nodes, and/or metastatic.

The objective of the systematic review and meta-analysis was to evaluate whether the choice between two radiotracers, (11)C-choline ((11)C-cho) and (18)F-fluorocholine ((18)F-FCH) for PET/CT, and different acquisition protocols contributed to detect metastases for patients with biochemical recurrence of prostate cancer after radical prostatectomy or radiotherapy.

The purpose of active surveillance (AS) is to reduce overtreatment of men with localized prostate cancer (PCa) without compromising survival. The objective of this study was to update a large Scandinavian single-center AS cohort.

Purpose: In this prospective survey of referring physicians, we investigated whether and how Gallium-68 Prostate Specific Membrane Antigen Positron Emission Tomography/Computed Tomography (PSMA-11 PET/CT) affects the actually implemented management of prostate cancer patients wih biochemical recurrence (BCR).

To examine the characteristics and management of earlier (within 5 years) vs later (after 5 years) biochemical recurrence (BCR) after radical prostatectomy (RP).

Between October 2000 and October 2009, 1597 men underwent open retropubic RP.

Prostate cancer can be treated with several different modalities, including radiation treatment. Various prognostic tools have been developed to aid decision making by providing estimates of the probability of different outcomes.

According to the novel prostate cancer (PCa) grade grouping, men with Gleason score 8 should be included in the grade group 4 regardless of primary and secondary scores. We aimed at evaluating the effect of Gleason patterns on the risk of recurrence in men with grade group 4 PCa.

Immunosuppressive cytokines have the potential to promote prostate cancer progression. Assessing their longitudinal changes may implicate mechanisms of progression, treatment resistance, and suggest new therapeutic targets.

We aimed to investigate the predictive factor of erectile dysfunction (ED) in prostate cancer (PCa) patients who underwent low-dose permanent I(125) seed implant brachytherapy and to investigate if ED could represent a patient's reported outcome measures (PROMs) of efficacy of BT and indirectly associated with biochemical recurrence free survival (BRFS).

BACKGROUND: Cigarette smoking seems to be associated with prostate cancer (PCa) incidence and mortality.

The aim of the present study was to investigate the prognostic role of metallothionein-2A (MT-2A), E-cadherin, interleukin-6 (IL-6), cyclin-E, proliferating cell nuclear antigen (PCNA) and B cell lymphoma (Bcl)-2 in the biochemical recurrence of prostate cancer (PCa) using tissue microarray immunostaining.

Biochemical recurrence (BCR) after primary treatment of localized prostate cancer does not necessarily lead to clinically apparent progressive disease. To aid in prognostication, the European Association of Urology prostate cancer guidelines panel undertook a systematic review and successfully developed a novel BCR risk stratification system (groups with a low risk or high risk of BCR) based on disease and prostate-specific antigen characteristics.

INTRODUCTION - High and very high-risk prostate cancers are tumors that display great variation in their progression, making their behaviour and consequent prognosis difficult to predict. We analyse preoperative and postoperative risk factors that could influence biochemical recurrence of these tumors.

The aim of this study was to investigate the effect of positive surgical margin (PSM) without extraprostatic extension after robot-assisted radical prostatectomy (RARP).

The fast-increasing use of positron emission tomography (PET) with prostate-specific membrane antigen (PSMA) ligand for the imaging of prostate cancer (PCA) biochemical recurrence has led to a rapid change in treatment concepts.

To evaluate whether prediction of biochemical recurrence (BCR) after radical prostatectomy (RP) is enhanced by any of six parameters: prostate volume, total tumor volume (TV), high grade TV, ratio of high grade TV to TV, ratio of TV to prostate volume and/or ratio of high grade TV to prostate volume.

OBJECTIVE - To compare the short-term oncological and HRQOL outcomes between open (ORP) and robotic-assisted (RARP) radical prostatectomy in the population-based Victorian Prostate Cancer Registry (PCR).

PATIENTS AND METHODS - This is a prospective cohort of prostate cancer patients who had RP (1117 ORP and 885 RARP) between January 2009 and June 2012.

To compare a standard radio-oncological and a surgical biochemical failure definition after combined-modality radiation therapy (CRT) in men with intermediate- and high-risk prostate cancer.

425 men were treated with external beam radiotherapy (59.

The aim of the present study was to assess the cost-effectiveness of extended pelvic lymph node dissection (ePLND) compared to neoadjuvant chemohormonal therapy using gonadotropin-releasing hormone agonist/antagonist and estramustine.

Intermediate clinical endpoints (ICEs) might aid in trial design and potentially expedite study results. However, little is known about the most informative ICE for patients receiving salvage radiation therapy (sRT) after radical prostatectomy.

Recently, prostate-specific membrane antigen (PSMA) targeted PET-imaging has emerged as new method of staging and restaging of prostate cancer. Most published studies have investigated the diagnostic potential of 68Ga-labeled PSMA-agents which are excreted renally.

After primary treatment, biochemical relapse (BCR) occurs in a substantial number of patients with prostate cancer (PCa). PET/CT imaging with prostate-specific membrane antigen based tracers (68Ga-PSMA) has shown promising results for BCR patients.

Biochemical recurrence (BCR), or an elevation in prostate-specific antigen in men after treatment for localized prostate cancer, is an early indication of clinical progression, distant metastases, and mortality.

Prostate cancer (PC) is the most frequent solid tumor in men and the third most common cause of cancer mortality among men in developed countries. Current imaging modalities like ultrasound (US), computerized tomography (CT), magnetic resonance imaging (MRI) and choline based positron emission (PET) tracing have disappointing sensitivity for detection of nodal metastasis and small tumor recurrence.

Positive surgical margin (PSM) extension reported as focal or non-focal/extensive is an important pathologic prognostic parameter after radical prostatectomy. Likewise, there is limited or no agreement on how to measure and what the best cut-off points to be used in practice are.

To identify new biomarkers for the biochemical recurrence (BCR) of prostate adenocarcinoma.

Clinical information of 500 prostate adenocarcinoma patients and their 152 RNA-sequencing and protein-array data from The Cancer Genome Atlas (TCGA) were separated into a discovery-set and a validation-set.

The present study evaluated the incidence and prognostic value of second primary cancers in patients with prostate cancer (PCa) who had undergone radical prostatectomy (RP).

From 2003 to 2013, 1915 patients who had undergone RP were included in the present analysis.

African-American (AA) men have the greatest incidence of and disease-specific mortality from prostate cancer of any racial group. Although encouraging oncologic and functional outcomes have been reported with prostate cancer cryotherapy, little is known about how ethnicity can potentially affect the oncologic outcomes of primary cryotherapy.

We sought to explore the impact of surgical wait time (SWT) to robot-assisted radical prostatectomy (RARP) on biochemical recurrence (BCR).

PET/CT with (68)Ga-labelled prostate-specific membrane antigen (PSMA)-ligands has been proven to establish a promising imaging modality in the work-up of prostate cancer (PC) patients with biochemical relapse.

Whether men with Gleason 3+4 prostate cancer are appropriate active surveillance (AS) candidates remains a matter of debate.

to evaluate the effects of initial Gleason grade 3+3 or 3+4 on clinical outcomes during AS.

The aim of this study was to evaluate the biochemical recurrence (BCR) in patients with high-risk prostate cancer (PCa) treated with radical prostatectomy (RP) or radiotherapy (RT) plus androgen deprivation therapy (ADT).
