177Lu-Prostate-Specific Membrane Antigen Super Scan and Good Response Even After 1 Cycle of Radioligand Therapy.

A 76-year-old man with castration-resistant prostate cancer and widespread skeletal metastases underwent 2 cycles of Lu-prostate-specific membrane antigen (PSMA) 617 therapy in our department. Whole-body Lu-PSMA scan after the first cycle showed diffuse skeletal PSMA-avid lesions, whereas no PSMA uptake was evident in the kidneys with minimal PSMA uptake by salivary glands (super scan). After 6 weeks, he received the second dose of Lu-PSMA and whole-body scan after the treatment showed remarkable resolution...


Prostate Cancer Lytic Bone Metastases Imaged With 18F-Fluorocholine PET/CT.

A 76-year-old man with metastatic prostate cancer and back pain was referred for palliative radiotherapy. Staging F-fluorocholine PET/CT scan revealed fluorocholine-avid prostate mass, extensive lymphadenopathy, lung nodules, and extensive osteolytic lesions throughout the axial skeleton. Prostate cancer bone metastases are predominantly sclerotic in nature. We present F-fluorocholine PET/CT imaging of prostate cancer with very rare lytic bone metastases.

What is the best timing of repeated CT scan in mild head trauma with an initial positive CT scan?

Mild traumatic brain injury (MTBI) is among the most common causes of A&E admission. Current Guidelines have clearly evidenced risk factors and neurological signs that should suggest a head CT scan at admission and indications to the first repeated scan. However, the role and frequency of further repeated CT scans after an initial positive scan is still unclear.


Reporting and Handling of Indeterminate Bone Scan Results in the Staging of Prostate Cancer: A Systematic Review.

Bone scintigraphy is key in imaging skeletal metastases in newly diagnosed prostate cancer. Unfortunately, a notable proportion of scans are not readily classified as positive or negative but deemed indeterminate. The extent of reporting of indeterminate bone scans and how such scans are handled in clinical trials are not known. A systematic review was conducted using electronic databases up to October 2016. The main outcome of interest was the reporting of indeterminate bone scans, analyses of how such sca...

A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical pra...

To Scan or Not to Scan: Horses and Zebras.

Incidental Detection of Meningioma by 18F-FMAU PET/CT in a Patient With Suspected Prostate Cancer.

We report on an incidental detection of a meningioma on [F]-2'-fluoro-5-methyl-1-beta-D-arabinofuranosyluracil (F-FMAU) PET/CT scan that was performed during a prospective investigation of F-FMAU PET/CT for targeted biopsy of potential sites of tumor in men with suspected prostate cancer based on elevated prostate-specific antigen level. Neither prostate multiparamteric MRI nor F-FMAU PET/CT localized small volume Gleason 3 + 3 tumor deposits. However, an incidental focal high accumulation of F-FMAU was obs...

Subtle excess in lifetime cancer risk related to CT scanning in Spanish young people.

CT scan is a life-saving medical diagnostic tool, entailing higher levels of ionising radiation exposure than conventional radiography, which may result in an increase in cancer risk, particularly in children. Information about the use and potential health effects of CT scan imaging among young people in Spain is scarce.

Is endoscopic surveillance necessary for patients who undergo total gastrectomy for gastric cancer?

There have been only a few reports investigating the clinical efficacy of follow-up endoscopy for detection of recurrent gastric cancer after total gastrectomy (TG). We reviewed the records of 747 patients undergoing TG from 2003 to 2012 and enrolled 267 patients (70 with early gastric cancer (EGC) and 197 with advanced gastric cancer (AGC)), who received one or more follow-up endoscopy and contrast abdominal computed tomography (CT) scan. We found no tumor recurrence in the 70 EGC patients during the mean ...

Addressing Survivorship in Cancer Care.

As a disease, cancer can affect an individual's well-being, from physical to psychological, social, and even spiritual wellness. The cancer survivor population must navigate a complex, constantly evolving field, with the assistance of their care team, to conquer the disease. To address the unmet needs of the cancer survivorship community, NCCN conducted an environmental scan of existing and emerging aspects of survivorship cancer care through stakeholder meetings with survivors and patient advocacy groups t...

68Ga-Prostate-Specific Membrane Antigen PET/CT in Triple-Negative Breast Cancer.

The prostate-specific membrane antigen (PSMA) is a transmembrane protein with elevated expression in prostate cancer cells. Breast cancer also shows PSMA expression. We present the case of a 30-year-old woman with triple-negative bilateral breast carcinoma who underwent bilateral mastectomy, chemotherapy, and radiotherapy. She developed a left chest wall and liver recurrence after primary therapy. Her recurrent disease was also triple-negative. In view of the known poor prognosis and very limited therapeuti...

Whole body bone SPET/CT can successfully replace the conventional bone scan in breast cancer patients. A prospective study of 257 patients.

Single photon emission tomography/computed tomography (SPET/CT) is usually recommended after ambiguous whole body bone scan (WBS) findings. We investigated the value of routine 2-field ("near" whole-body) SPET/CT application in breast cancer (BC) patients.

Schmorl's Node: Confusion Still Persists in 68Ga-Prostate-Specific Membrane Antigen Ligand PET/CT.

Ga-prostate-specific membrane antigen (PSMA) ligand PET/CT is commonly believed to be prostate specific as the name itself suggests. However, PSMA-expressing nonprostatic cancers as well as benign lesions are continuously being added to the list. We reported PSMA-expressing Schmorl's node in L1 vertebra of a 74-year-old man with prostate cancer. Prostate-specific membrane antigen expression in the vertebral lesion raised a metastatic suspicion. However, on analysis of previous CT scan done 2 years before, t...

More accurate than MRI measurement of tumor size in breast cancer by using the peri-tumoral halo uptake layer method of the F-FDG PET/CT scan.

To evaluate the reliability of a method using the peri-tumoral halo layer (PHL) for assessing tumor size in breast cancer patients on the fluorine-18-fluorodeoxy glucose positron emission tomography/computed tomography (F-FDG PET/CT) scan compared to MRI and pathology.

Dual scan CT image recovery from truncated projections.

There are computerized tomography (CT) scanners available commercially for imaging small objects and they are often categorized as mini-CT X-ray machines. One major limitation of these machines is their inability to scan large objects with good image quality because of the truncation of projection data. An algorithm is proposed in this work which enables such machines to scan large objects while maintaining the quality of the recovered image.

Gemstone spectral imaging in lung cancer: A preliminary study.

The present study aimed to evaluate the application of gemstone spectral imaging (GSI) for multi-parameter quantitative measurement in lung cancer.The study retrospectively enrolled 30 patients with lung cancer who underwent chest contrast enhanced CT scan with GSI mode. The GSI viewer was used for image display and data analysis. Optimal energy value, CT values at 40 keV, 70 keV and optimal energy level, spectral curve slope, effective atomic number (Zeff), iodine concentration (IC), and water concentratio...

Radioligand therapy of metastatic castration-resistant prostate cancer: current approaches.

Prostate Cancer is the forth most common type of cancer. Prostate-specific membrane antigen (PSMA) is anchored in the cell membrane of prostate epithelial cells. PSMA is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer. Therefore it is an appropriate target for diagnostic and therapy of prostate cancer and its metastases. This article discusses several articles on radionuclide treatments in prostate cancer and the results on PSMA therapy with either beta or alpha em...

Impact of long-term androgen deprivation therapy on PSMA ligand PET/CT in patients with castration-sensitive prostate cancer.

Since the introduction of PSMA PET/CT with Ga-PSMA-11, this modality for imaging prostate cancer (PC) has spread worldwide. Preclinical studies have demonstrated that short-term androgen deprivation therapy (ADT) can significantly increase PSMA expression on PC cells. Additionally, retrospective clinical data in large patient cohorts suggest a positive association between ongoing ADT and a pathological PSMA PET/CT scan. The present evaluation was conducted to further analyse the influence of long-term ADT o...

Developing new age-specific prostate-specific antigen thresholds for testing for prostate cancer.

To examine whether age-related reference ranges for "normal" prostate-specific antigen (PSA) change (determined in men without prostate cancer) can be used to identify men at high risk of having prostate cancer.

The Role of Testosterone Therapy in the Setting of Prostate Cancer.

The role of testosterone in the development of prostate cancer and the safety of testosterone therapy (TTh) after prostate cancer treatment, or in the setting of active surveillance, remains controversial. There are many concerns about using TTh in men, particularly those with a history of prostate cancer, ranging from a possible increased risk of cardiovascular disease to cancer progression or recurrence. With many prostate cancer patients living longer, and hypogonadism having significant morbidity, much ...

Modelling human prostate cancer: Rat models.

Prostate cancer is the second most common cancer in men, affecting approximately 1.1 million men worldwide. In this way, the study of prostate cancer biopathology and the study of new potential therapies is of paramount importance. Several rat models were developed over the years to study prostate cancer, namely spontaneous models, chemically-induced models, implantation of cancer cell lines and genetically-engineered models. This manuscript aimed to provide the readers with an overview of the rat models of...

Scan-rescan reproducibility of diastolic left ventricular kinetic energy, viscous energy loss and vorticity assessment using 4D flow MRI: analysis in healthy subjects.

The aim of the current study was to assess the scan-rescan reproducibility of left ventricular (LV) kinetic energy (KE), viscous energy loss (EL) and vorticity during diastole from four-dimensional flow magnetic resonance imaging (4D flow MRI) in healthy subjects. Twelve volunteers (age 27 ± 3 years) underwent whole-heart 4D flow MRI twice in one session. In-scan consistency was evaluated by correlation between KE and EL. ELindex was computed to measure the amount of EL relative to KE over diastole. ...

68Ga-Labeled Prostate-Specific Membrane Antigen Uptake in Pheochromocytoma: An Incidental Finding in PET/CT Scan.

We report a case of adenocarcinoma prostate treated previously with radical prostatectomy and hormonal therapy who underwent Ga-labeled prostate-specific membrane antigen PET/CT for recurrence evaluation. In addition to radiotracer uptake in the prostate bed, unusual intense prostate-specific membrane antigen uptake was also noted in the left adrenal gland. With a clinical suspicion of pheochromocytoma, Ga-DOTANOC PET/CT was done, which revealed tracer-avid left adrenal lesion.

Quantitation of the anticancer drug abiraterone and its metabolite Δ(4)-abiraterone in human plasma using high-resolution mass spectrometry.

Abiraterone acetate is administered as a prodrug to patients with metastatic, castration-resistant prostate cancer (mCRPC) and is readily metabolized into the potent 17a-hydroxylase/17,20-lyase (CYP17) enzyme inhibitor and androgen receptor inhibitor abiraterone and Δ(4)-abiraterone (D4A), respectively. To investigate pharmacokinetic variability in abiraterone acetate metabolism we developed highly sensitive liquid chromatography/mass spectrometry (LC/MS) assays for the simultaneous quantitation of abirate...
