BACKGROUND 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. CT urography (CT-U) is an established method, which allows assessment of urological malignancies. The study pres...

BACKGROUND AND PURPOSE We investigated the role of 68Ga-PSMA-PET (PSMA) to determine the location of disease recurrence in those with a rising PSA following definitive external beam radiation treatment (EBRT). MATERIALS AND METHODS 538men were treated with image guided EBRT to a dose of 78 or 82Gy between 2007 and 2014. Patients at least 24months post EBRT with biochemical failure (nadir+2) u...

relapse at low PSA values <1 ng ml−1, the obtained detection rates of 99mTc-labeled PSMA-SPECT/CT are lower than those reported by 68Ga-PSMA PET/CT imaging.1 This is in line with our experiences in early recurrent prostate cancer patients and low PSA values investigated with PSMA tracers for SPECT/CT imaging.3 Although very useful for PSMA-radioguided surgery,4,5 111 In-labeled PSMA I&T (or 99m...

Prostate-specific membrane antigen (PSMA) is a promising target in prostate cancer. Recently, we started the first-in-human treatment with an α-radionuclide-labeled PSMA ligand. Although the case series is still ongoing, we here report in advance about two patients in highly challenging clinical situations who showed a complete response to 225Ac-PSMA-617 therapy. METHODS 68Ga-PSMA-11 PET/CT v...

The management of patients with biochemical recurrence (BCR) after definitive treatment for prostate cancer remains controversial. Our aim was to determine survival rates and complications of salvage lymph node dissection (sLND) in patients with recurrent prostate cancer after radical prostatectomy, while evaluating biochemical response (BR) with two different positron emission tomography/compu...

BACKGROUND In this study, we prospectively evaluate the diagnostic potential of a gallium-68 (68Ga) prostate-specific membrane antigen (PSMA)-binding ligand and positron emission tomography (PET) in detecting metastatic lesions in patients with renal tumour. The secondary aim was to determine whether the findings would result in the alteration of patient management. RESULTS Ten patients with ...

Prostate-specific membrane antigen (PSMA) is a promising target in prostate cancer. Recently, we started the first-in-human treatment with an α-radionuclide–labeled PSMA ligand. Although the case series is still ongoing, we here report in advance about two patients in highly challenging clinical situations who showed a complete response to 225AcPSMA-617 therapy. Methods: 68Ga-PSMA-11 PET/CT val...

AIM To evaluate 68Ga-PSMA ligand positron-emission tomography-computed tomography (PET/CT)-based radiotherapy for lymph node metastases of prostate cancer after primary therapy. PATIENTS AND METHODS Twenty-three patients received radiotherapy for PSMA ligand-positive lymph node metastases. RESULTS The median follow-up time was 12.4 (range=6.0-28.5) months. The median pre-treatment prostate-...

BACKGROUND The aim of this study was to evaluate the diagnostic value of the asphericity (ASP) as a novel quantitative parameter, reflecting the spatial heterogeneity of tracer uptake, in the staging process of patients with 68Ga-PSMA-HBED-CC positron emission tomography (PET)-positive prostate cancer (PC). In this study, 37 patients (median age 72 years, range 52-82 years) with newly diagnosed...

Objectives: Clinical approach of prostate cancer (PCa) biochemical recurrence (BCR) is an ever-changing topic. Prostate-specific membrane antigen positron emission tomography ([68Ga]Ga-PSMA-11 PET-CTPSMA PET-CT) has shown good potential in this field. The aim to evaluate PSMA PET-CT detection rate PCa BCR and assess its impact on clinical outcome. Material methods: Out 319 patients with who und...
