PURPOSE: We implemented a statewide intervention to improve imaging utilization for staging of men with newly diagnosed prostate cancer patients. MATERIALS AND METHODS: The Michigan Urological Surgery Improvement Collaborative, a quality improvement collaborative comprised of 42 diverse practices representing approximately 85% of the urologists in Michigan, has developed imaging appropriateness criteria (PSA > 20, Gleason score 7 or higher, clinical stage T3 or higher) that minimize unnecessary imaging with bone scan and computed tomography...

(99m)Tc-MDP whole-body bone scintigraphy is a highly sensitive imaging method that has been used for decades to evaluate prostate cancer bone metastasis based on its availability and low cost; however, because of accumulation of this radiotracer in degenerative, traumatic, and inflammatory lesions, it suffers from noncomparable specificity. The modality is also used to monitor response to therapy and to predict patients' prognosis. As planar imaging may not give enough information for lesion detection or anatomical localization, it can be supplemented with SPECT to increase image contrast particularly in the evaluation of small and complex skeleton...

AIM: Castrate-resistant prostate cancer (CRPC) often shows histological evidence of neuroendocrine differentiation (NED). To evaluate the extent of NED in patients with CRPC, we used PET/CT with Ga-[DOTA-Tyr]-octreotate (Ga-DOTA-TATE), a somatostatin analog that binds somatostatin receptor 2 with high affinity. This radiotracer is used in imaging of neuroendocrine tumors. METHODS: Twelve patients (mean age, 65 [SD, 12] years) with CRPC were studied. Their mean prostate-specific antigen level at scanning was 85...

In prostate cancer patients, if bone scan demonstrates a solitary lesion in atypical area, this is possibly an indication of metastatic disease. Therefore, biopsy confirmation is required to determine the nature of the abnormality and therefore dictates further staging investigations and treatment options.

Radiochemical studies and biological evaluation in animal models have shown superior radiochemical properties and better clearance pattern for Lu-DOTMP compared with Lu-EDTMP, an agent recently proven to be efficacious and safe for metastatic bone pain palliation. This prompted us to initiate the clinical evaluation of Lu-DOTMP. The images represent the whole-body scans of a prostate cancer patient (man, 67 years) with skeletal metastases recorded after administering 3.7 GBq (100 mCi) of Lu-DOTMP.

Paget disease is a chronic disorder resulting in enlarged and misshapen bones, and is caused by disorganized bone remodeling. We present the case of an 85-year-old man with prostatic adenocarcinoma and known Paget disease of the right iliac bone who underwent Ga-prostate-specific membrane antigen ligand, C-acetate, and F-fluoride PET/CT for restaging of cancer. On all PET scans, increased tracer accumulation was observed in Paget disease of bone. Besides that Paget disease may mimic metastases on PET/CT using various radiotracers, including Ga-prostate-specific membrane antigen ligands and C-acetate, this case highlights the potential of multiparametric disease characterization on PET...

PURPOSE: We retrospectively evaluated the utility of (68)Ga-PSMA-11 PET for planning (223)RaCl2 therapy of patients with metastatic prostate cancer and its impact on the therapeutic response as determined by PSA and ALP, as well as the correlation of PSA changes with the results of PSMA-PET, follow-up scans. METHODS: Sixty-three patients with a median age of 73 years who underwent a total of 307 cycles of therapy with (223)RaCl2 were analyzed. In thirty-one patients bone scans and radiological imaging was performed for pre therapeutic imaging (group 1)...

This article shall describe the role of (18)F-Sodium Fluoride ((18)F-NaF) PET/CT bone scanning in the staging of breast and prostate cancer. (18)F-NaF PET was initially utilised as a bone scanning agent in the 1960s and early 1970s, however its usage was restricted by the then available gamma cameras. The advent of hybrid PET/CT cameras in the late 1990s has shown a resurgence of interest in its usage and role. After a brief introduction, this paper will describe the radiopharmaceutical properties, dosimetry, pharmacokinetics, and mechanism of uptake of (18)F-NaF...

BACKGROUND: Meeting quality of care standards in oncology is recognized as important by physicians, professional organizations, and payers. Data from a population-based cohort of patients with prostate cancer were used to examine whether receipt of care was consistent with published consensus metrics and whether receiving high-quality care was associated with less patient-reported treatment decisional regret. METHODS: Patients with incident prostate cancer were enrolled in collaboration with the North Carolina Central Cancer Registry, with an oversampling of minority patients...

Antiandrogen withdrawal syndrome (AWS) is a well-established phenomenon in prostate cancer treated with combined androgen blockade (CAB). AWS is generally defined as subjective and/or objective improvement following discontinuation of an antiandrogen. However, the duration of the AWS response is usually limited. In addition, a complete response is quite rare. We herein present the case of a patient who achieved complete response from AWS, with the duration of this response lasting for >6 years. A 72-year-old man with metastatic prostate cancer received CAB with a luteinizing hormone-releasing hormone analog and bicalutamide...

: In the absence of data from randomized trials, the role of local treatment in metastatic prostate cancer (PCa) is gaining interest. Our study aimed to assess perioperative and long-term oncologic outcomes of radical prostatectomy (RP) in a selected cohort of 11 patients with oligometastatic disease treated with RP and extended pelvic lymph node dissection between 2006 and 2011. Oligometastatic disease was defined as the presence of five or fewer bone lesions at bone scan with or without suspicious pelvic or retroperitoneal nodal involvement at preoperative imaging...

65-year-old man with left-sided pelvic pain on evaluation was found to have features suggestive of either Paget disease or prostatic bone metastasis of the left hemipelvis based on Tc-MDP bone scan and MRI. Ga-PSMA PET/CT to assess the possibility of primary prostate cancer and if present to stage it helped to rule out prostate cancer because of absence of focal abnormal increased tracer uptake in the prostate gland. However, false-positive tracer uptake was noted in the left hemipelvis, which was subject to biopsy and histopathologically proven to be Paget disease involvement...

OBJECTIVE: In Japan, flutamide had been commonly used as second-line alternative antiandrogen hormonal therapy for metastatic castration-resistant prostate cancer that relapses after initial hormone therapy before new androgen pathway inhibitors became available. In this study, we attempted to identify predictive factors for efficacy of alternative antiandrogen as second-line hormone therapy. METHODS: We identified consecutive 65 patients with metastatic castration-resistant prostate cancer who were treated with alternative antiandrogen as second-line hormonal therapy (bicalutamide to flutamide)...

BACKGROUND: There is an increasing concern in the role of microRNA (miRNA) in the pathogenesis of bone metastasis (BM) secondary to prostate cancer (CaP). In this exploratory study, we hypothesized that the expression of vinculin (VCL) and chemokine X3C ligand 1 (CX3CL1) might be downregulated in clinical samples, most likely due to the posttranscriptional modification by microRNAs. Targeted genes would be upregulated upon transfection of the bone metastatic prostate cancer cell line, PC3, with specific microRNA inhibitors...

BACKGROUND: Although race is associated with prostate cancer progression in early stage disease, once men have advanced disease, it is unclear whether race continues to predict a poor outcome. The authors hypothesized that, in an equal-access setting among patients with castration-resistant prostate cancer (CRPC) and no known metastases (M0/Mx), black men would receive imaging tests at similar rates as nonblack men (ie, there would be an equal opportunity to detect metastases) but would have a higher risk of metastatic disease...
