Purpose: To investigate if imaging biomarkers derived from 3-Tesla dual-tracer [(18)F]fluoromethylcholine (FMC) and [Ga]Ga-PSMA conjugate 11 (PSMA)-positron emission tomography can adequately predict clinically significant prostate cancer (csPC).

Methods: We assessed 77 biopsy-proven PC patients who underwent 3T dual-tracer PET/mpMRI followed by radical prostatectomy (RP) between 2014 and 2017. We performed a retrospective lesion-based analysis of all cancer foci and compared it to whole-mount histopathology of the RP specimen.

Article Synopsis
  • Androgen deprivation therapy (ADT) is a common treatment for prostate cancer (PCa), but many cases eventually become resistant to this approach.
  • Research has indicated that thyroid hormones, particularly thyroxine (T4) and triiodo-L-thyronine (T3), may also play a role in PCa progression.
  • Low levels of the thyroid hormone binding protein μ-Crystallin (CRYM) in PCa patients are linked to worse outcomes, suggesting CRYM may help regulate PCa growth by counteracting thyroid and androgen signaling.

(1) Background: Lymphoepithelial carcinoma of the hypopharynx and larynx is a rare tumor with fewer than 50 cases in the published literature. We present a literature review to discuss the clinical findings, viral or genetic associations, diagnostic challenges, histopathological findings and therapeutic aspects of the disease. (2) Methods: A comprehensive literature review was performed through MEDLINE/PubMed from 1968 to 2018.

Purpose: Primary staging of prostate cancer relies on modalities, which are limited. We evaluate simultaneous [Ga]Ga-PSMA-11 PET (PSMA-PET)/MRI as a new diagnostic method for primary tumor-node-metastasis staging compared with histology and its impact on therapeutic decisions.

Experimental Design: We investigated 122 patients with PSMA-PET/MRI prior to planned radical prostatectomy (RP).

Purpose: Medullary thyroid carcinoma (MTC) is characterized by a high rate of metastasis. In this study we evaluated the ability of [F]DOPA PET/ceCT to stage MTC in patients with suspicious thyroid nodules and pathologically elevated serum calcitonin (Ctn) levels prior to total thyroidectomy and lymph node (LN) dissection.

Methods: A group of 32 patients with sonographically suspicious thyroid nodules and pathologically elevated basal Ctn (bCtn) and stimulated Ctn (sCtn) levels underwent DOPA PET/ceCT prior to surgery.

Aim: The aim of this study was to retrospectively analyze the prognostic value of combined Tc-macroaggregated albumin (MAA) SPECT/CT and [F]-fluoroethylcholine (FEC) PET/CT before radioembolization for survival of patients with intermediate-stage hepatocellular carcinoma.

Methods: Twenty-four patients with known hepatocellular carcinoma Barcelona Clinic Liver Cancer stage B were eligible for this analysis. All patients were scheduled for radioembolization and received a pretherapeutic [F]FEC PET/CT scan as well as Tc-MAA SPECT/CT for hepatopulmonary shunting.

Unlabelled: The aim of this study was to evaluate (18)F-fluoroethylcholine PET/CT as a metabolic imaging technique for the assessment of treatment response to (90)Y radioembolization in patients with locally advanced hepatocellular carcinoma (HCC).

Methods: Thirty-four HCC patients undergoing 78 (18)F-fluoroethylcholine PET/CT scans were identified for this study. Patients with initial or follow-up metastastic disease (n = 9) were excluded at the time point of the metastatic occurrence as well as patients with negative α-fetoprotein (AFP; n = 1), resulting in 24 patients and 57 scans that were eligible.

Purpose: The aim of this study is to non-invasively assess early, irradiation-induced normal tissue alterations via metabolic imaging with 3'-deoxy-3'-[(18) F]fluorothymidine ([(18) F]FLT).

Procedures: Twenty-nine male C57BL/6 mice were investigated by [(18) F]FLT positron emission tomography for 7 days after total body irradiation (1, 4, and 8 Gy) versus 'sham' irradiation (0 Gy). Target/background ratios were determined.

Purpose: The pretherapeutic assessment of prostate cancer is challenging and still holds the risk of over- or undertreatment. This prospective trial investigates positron emission tomography (PET) with [(18)F]fluoroethylcholine (FEC) combined with endorectal magnetic resonance imaging (MRI) for the assessment of primary prostate cancer.

Experimental Design: Patients with prostate cancer based on needle biopsy findings, scheduled for radical prostatectomy, were assessed by FEC-PET and MRI in identical positioning.
