Evaluating the Utility of 18F-FDG PET/CT in Cancer of Unknown Primary
18F-FDG PET/CT plays a complementary role in CUP diagnostic work-up and was able to determine the likely primary site in 41% of cases. OS is improved with primary site identification, demonstrating the value of access to diagnostic 18F-FDG PET/CT for CUP patients.

The LUTADOSE trial: tumour dosimetry after the first administration predicts PFS in GEP NET patients treated with 177Lu-DOTATATE
Patients with a mean tumour absorbed dose lower than the best cut-off value of 10.6 Gy after first cycle had a significantly shorter median PFS (HR 8.6, 95% CI: 2–37).

Prognostic significance of a negative PSMA PET/CT in biochemical recurrence of prostate cancer
Salvage RT is associated with delayed clinical progression in patients with post radical prostatectomy biochemical recurrence and negative PSMA PET/CT (HR: 0.2, p=0.03). Median follow-up was 39 months.
pubmed.ncbi.nlm.nih.govEmission of internal conversion electrons rather than Auger electrons increased the nucleus-absorbed dose for 161Tb compared with 177Lu
161Tb-labeled DOTATATE and DOTA-LM3 delivered 3.6 and 3.8 times higher doses to the cell nucleus, respectively, than their 177Lu-labeled counterparts. This increased nucleus-absorbed dose was mainly due to the additional emission of IC and not Auger electrons by 161Tb.

Pediatric Papillary Thyroid Carcinoma: Outcomes After Surgery Without Adjuvant Radioactive Iodine
Pediatric PTC patients, including those with LN metastases, may achieve excellent long-term outcomes without RAI.
academic.oup.comQuantitative PSMA PET and Clinical Outcomes in mCRPC Following 177Lu-PSMA-617 (VISION Trial)
Baseline tumor SUVmean from PSMA PET is the strongest predictor of treatment efficacy with 177Lu-PSMA-617 in mCRPC, with higher SUVmean values correlating with improved outcomes in the VISION trial.
pubs.rsna.orgMay the Nuclear Medicine be with you! Neuroendocrine tumours and the return of nuclear medicine
Authors discuss the advancements in NET management, likening radioligands to "midi-chlorians" from the Star Wars series, and emphasize the potential of novel imaging and therapeutic agents in improving personalized care.

Enhancing 177Lu-DOTA-TATE efficacy by combining it with metronomic chemotherapeutics
Hydroxyurea, gemcitabine and triapine all increased cell size, SSTR2A expression, and 177Lu-DOTA-TATE uptake, whilst reducing cell metabolic viability in U2OS + SSTR2A cells when compared to 177Lu-DOTA-TATE monotherapy.

PRRT with 90Y-DOTATOC and 177Lu-DOTATATE demonstrated a 57% disease control rate in meningioma patients with radiologic recurrence after standard therapies. Median PFS and OS were 16 and 36 months, respectively. PRRT was well tolerated and shows potential as a retreatment option.
