We present a 60-year-old man with known prostate cancer treated with robot-assisted radical prostatectomy. Prostate-specific antigen levels did not decline accordingly, and a second Ga-PSMA PET/CT demonstrated a new focus with high Ga-PSMA uptake in the pancreatic tail. A subsequent CT scan did not display the lesion as a typical pancreatic tumor, and a spleen scintigraphy was also negative excluding an ectopic intrapancreatic accessory spleen. Ga-DOTATOC PET/CT showed uptake in the same area of the pancreatic tail consistent with a neuroendocrine tumor. This case illustrates that neuroendocrine tumors can be important pitfalls in Ga-PSMA PET/CT performed in prostate cancer patients.

We present 2 cases of pancreatic neuroendocrine tumor with diffuse involvement of the entire pancreas. One case with G2 pancreatic neuroendocrine tumor showed nearly normal pancreatic shape and signal...
An 81-year-old man with prostate adenocarcinoma (Gleason 4 + 3 = 7) treated with brachytherapy and intermittent androgen deprivation therapy was referred for serial Ga-prostate-specific membrane antig...
Prostate-specific membrane antigen (PSMA) is a transmembrane enzyme also known as folate hydrolase 1 highly expressed by prostate cancer (PCa) cells. However, PSMA overexpression by tumor-associated n...
99mTc-MIP-1404 SPECT/CT for Patients With Metastatic Prostate Cancer: Interobserver and Intraobserver Variability in Treatment-Related Longitudinal Tracer Uptake Assessments of Prostate-Specific Membrane Antigen-Positive Lesions.
Tc-MIP-1404 is a SPECT-suitable prostate-specific membrane antigen (PSMA) ligand for detection of prostate cancer. In patients with metastatic prostate cancer, there are no data as yet on interobserve...
Single-centre, prospective, diagnostic trial to evaluate the Prostate-Specific Membrane Antigen (PSMA-antigen) over-expression in metastatic castration resistant prostate cancer (mCRPC) an...
This phase I trial studies the impact of monosodium glutamate (MSG) on 68GA-PSMA-11 PET/CT in decreasing the salivary glands uptake in patients with prostate cancer. Prostate specific memb...
The purpose of this study is to determine if Prostate-Specific Membrane Antigen (PSMA) positron emission tomography (PET) scans used in this study accurate and better at imaging participan...
As choline transport and phosphorylation are upregulated in most cancers, including prostate cancer, positron emission tomography (PET) with choline tracers has found widespread use to det...
This phase I trial studies the side effects of 68GA-PSMA-11 PET imaging in patients with prostate cancer that has come back (recurrent). Gallium (68Ga) is a radiotracer that binds to a mol...
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
Proteins found in SEMEN. Major seminal plasma proteins are secretory proteins from the male sex accessory glands, such as the SEMINAL VESICLES and the PROSTATE. They include the seminal vesicle-specific antigen, an ejaculate clotting protein; and the PROSTATE-SPECIFIC ANTIGEN, a protease and an esterase.
Extracts prepared from pancreatic tissue that may contain the pancreatic enzymes or other specific uncharacterized factors or proteins with specific activities. PANCREATIN is a specific extract containing digestive enzymes and used to treat pancreatic insufficiency.
A family of trypsin-like SERINE ENDOPEPTIDASES that are expressed in a variety of cell types including human prostate epithelial cells. They are formed from tissue prokallikrein by action with TRYPSIN. They are highly similar to PROSTATE-SPECIFIC ANTIGEN. EC 188.8.131.52.
Benign Prostatic Hyperplasia (BPH)
An enlarged prostate (benign prostatic enlargement (BPE) or benign prostatic hyperplasia (BPH)) is common in men after the age of about 50. Having an enlarged prostate does not mean you have cancer. In some cases, an enlarged prostate can cause the ...
The pancreas secretes a number of important hormones into the digestive tract and the blood stream. Cancers are most commonly exocrine than endocrine (neuroendocrine) tumors. Functional tumors secrete hormones; Insulinoma, Gastrinoma, Somatostatinoma, VI...
Prostate cancer (cancer de prostata) Prostate cancer (cancer de prostata) is a form of cancer that develops in the prostate, a gland in the male reproductive system. Most prostate cancers are slow growing; however, there are cases of aggressive prostat...
