ConclusionsThese results suggest that compared with PI-RADS v2, PI-RADS v2.1 could be preferable for evaluating TZ lesions.

Authors: De Luca S, Fiori C, Bollito E, Garrou D, Aimar R, Cattaneo G, De Cillis S, Manfredi M, Tota D, Massa F, Passera R, Porpiglia F Abstract BACKGROUND: To evaluate if multiparametric magnetic resonance (mpMRI)- transrectal ultrasound (TRUS) fusion targeted biopsy (TBx) versus untargeted standard biopsy (SBx) may decrease the rate of pathological upgrading of Gleason score (GS) 3+4 prostate cancer (PCa) at radical prostatectomy (RP). We also evaluated the impact of percent pattern 4 and cribriform glands at biopsy in the risk of GS 3 + 4 = 7 upgrading. METHODS: 301 patients with GS 3+4 PCa on biopsy (159 SB...

ConclusionThis survey was an informative trial to understand the verification status of patient-specific IMRT QA measurements for prostate cancer. In most institutions, the point dose measurement and dose distribution differences met the desired criteria.

Authors: Abrahamyan L, Huszti E, Bremner KE, Pechlivanoglou P, Mitsakakis N, Krahn M Abstract The epidemiology of prostate cancer (PC) continues to change. We evaluated the changes in incidence, in average age at diagnosis, and in survival from 1992 to 2015 in Ontario. We compared the cumulative incidence of PC-specific and non PC-specific mortality using two algorithms for cause of death: Method 1 assigned deaths from 'other cancers' to non PC-specific causes, and Method 2 assigned these cases to PC-specific mortality. There were 188,714 cases diagnosed with PC between 1992-2015 in Ontario. The average age at diag...

We present images of 177Lu-DOTATATE scan and 68Ga-DOTATATE PET/CT scan conducted on a 65-year-old man with prostate cancer with neuroendocrine differentiation, whose disease progressed despite conventional treatment and 177Lu-PSMA radioligand therapy; however, an extraordinary radiographic tumor remission, biochemical response, and improvement of clinical symptoms were observed after the patient underwent 177Lu-DOTATATE peptide receptor radionuclide therapy.

A 63-year-old man, recently diagnosed with carcinoma of the prostate (Gleason’s score 4+4), with serum prostate-specific antigen 189.2 ng/mL, underwent 68Ga PSMA PET/CT scan for pretreatment staging. The study revealed abnormal tracer uptake in the prostatic bed region, the pelvic, abdominal, and mediastinal lymph nodes and diffuse metastases to the bilateral lungs. The lung metastasis was proved to be metastatic adenocarcinoma from analysis of bronchoalveolar lavage.

In a patient with recently diagnosed intermediate-risk prostate cancer, 68Ga-prostate-specific-membrane-antigen (PSMA) PET/CT for primary staging discovered increased 68Ga-PSMA uptake in spondylodiscitis in the thoracic spine. The bacteria Escherichia coli was found both in blood cultures and bone biopsies from the thoracic lesion. This case presents spondylodiscitis as a potential benign pitfall to be aware of when interpreting PSMA PET/CT in prostate cancer patients.

Primary retroperitoneal liposarcoma is an extremely rare malignant tumor. Herein, we report a case with an incidentally detected giant retroperitoneal liposarcoma on 68Ga-PSMA PET/CT during primary staging for prostate cancer.

We present a rare case of fluciclovine uptake in Paget disease in a 58-year-old man with suspected recurrent prostate cancer and asymmetric increased left hemipelvic uptake on imaging.

Conclusion SCG, similar to other sympathetic ganglia, show 68Ga-PSMA-11 uptake. SCG avidity may be of significance, especially in view of frequently occurring SCG oval or longitudinal shape, and moderate to high diffusion restriction in visual assessment, potentially suggesting malignancy on transverse MR plane. Diagnostic imaging specialists and clinicians should be aware of the above.
