MicroRNA-4521 goals hepatoma up-regulated proteins (HURP) in order to hinder your dangerous continuing development of breast cancer.
In the two patients, both radiotracers provided high image quality and a similar range of detection for metastatic lesions.
A 65-year-old man with treated prostate adenocarcinoma underwent 68Ga-PSMA-11 PET/CT scan for restaging due to significantly increased serum PSA levels. PET/CT showed bilateral adrenal masses with high 68Ga-PSMA-11 uptake. There was no other lesion suspicious for metastasis. The laboratory and imaging findings were consisted with isolated bilateral adrenal metastases from prostate adenocarcinoma. The patient received docetaxel chemotherapy in combination with androgen deprivation therapy. PSA levels gradually decreased during chemotherapy. Follow-up MRI showed the bilateral adrenal masses significantly decreased in size. This case demonstrates the usefulness of 68Ga-PSMA-11 PET/CT in identifying atypical metastasis from prostate adenocarcinoma.

We aimed to evaluate the role of 18F-FDG PET/CT in predicting patient outcome following chimeric antigen receptor T (CAR T) cells infusion in aggressive B-cell lymphoma.

18F-FDG PET/CT data before leukapheresis, before CAR T-cell infusion and 1 month (M1) after CAR T-cell infusion, from 72 patients were retrospectively analyzed. SUVmax, total lesion glycolysis (TLG), metabolic tumor volume (MTV), and parameters describing tumor kinetics were calculated for each 18F-FDG PET/CT performed. The aim was to evaluate the prognostic value of 18F-FDG PET/CT metabolic parameters for predicting progression-free survival (PFS) and overall survival (OS) following CAR T-cell therapy.

Regarding PFS, ∆MTVpre-CAR and ∆TLGpre-CAR were found to be more discriminating compared with metabolic parameters at preinfusion. Median PFS in patients with a ∆MTVpre-CAR of less than 300% was 6.8 months (95% confidence interval [CI], 2.8 months to not reached) compared with 2.8 months (95% CI, 0.9-3.0 months) for those with a value of 300% or greater (P = 0.004). Likewise, median PFS in patients with ∆TLGpre-CAR of less than 420% was 6.8 months (95% CI, 2.8 months to not reached) compared with 2.7 months (95% CI, 1.3-3.0 months) for those with a value of 420% or greater (P = 0.0148). Regarding OS, metabolic parameters at M1 were strongly associated with subsequent outcome. SUVmax at M1 with a cutoff value of 14 was the most predictive parameter in multivariate analysis, outweighing other clinicobiological variables (P < 0.0001).

Disease metabolic volume kinetics before infusion of CAR T cells seems to be superior to initial tumor bulk itself for predicting PFS. For OS, SUVmax at M1 might adequately segregate patients with different prognosis.

Two patients with different amyotrophic lateral sclerosis (ALS) phenotypes underwent 18F-THK5351 PET to visualize lesions undergoing astrogliosis by measuring monoamine oxidase B activity. Patient 1 was a 57-year-old man with flail leg syndrome. Elevated uptake was observed inside the motor cortex, corresponding to the leg area in a cortical homunculus. Patient 2 was a 64-year-old man with ALS-frontotemporal dementia semantic variant. Elevated uptake was observed around the left anterior temporal lobe. Both core lesions were consistent with their respective neurological features. Hence, 18F-THK5351 PET is a useful technique to assess ALS pathophysiology by visualizing the core lesions.

A 59-year-old man with a parapharyngeal paraganglioma incidentally discovered on a cervical swelling was referred to our nuclear medicine department for a morpho-metabolic assessment. An 18F-FDG PET/CT was initially performed and found an intense hypermetabolism of the lesion and a hypermetabolism of the periadrenal brown fat evoking catecholamine secretion. An additional 68Ga-DOTATOC PET/CT was performed, showing an overexpression of the somatostatin receptors of this isolated paraganglioma. After multidisciplinary discussion, a peptide receptor radionuclide therapy with somatostatin analogs using 177Lu-DOTATATE as a compassionate measure was carried out.
