Median duration of follow-up was 37.6 months (range 0.0-134.6 months) with a median OS from first cycle of PRRT 48.4 months (95% confidence interval 42.5-57.3 months). Patients with advanced NEN/NET or other somatostatin receptor-positive malignancies treated with 177Lu-DOTATATE at our centre had improved hr-QoL following iPRRT, with comparable toxicity and OS to other centres.

[203Pb]Pb-VMT-α-NET appears to be a safe and effective SPECT/CT tracer for imaging NETs larger than 1 cm and for normal organ and tumor radiation dosimetry. The chemically matched 203/212Pb theranostic pair offers the potential for a dosimetry-driven personalized treatment paradigm.

The standard management remains surgical resection, with tyrosine kinase inhibitors (TKIs) in RET mutation-positive or RET mutation-negative metastatic cases and/or Lutathera peptide receptor radionuclide therapy (PRRT) used in disseminated disease, and external beam radiotherapy for locally aggressive or infiltrative retaining a limited role...Of the 80 MTC patients reviewed, this case series highlights 10 atypical presentations in nine cases : 3 unusual tumors along with MTC, namely chondrosarcoma, carcinoma prostrate, and ectopic Cushing's syndrome; 4 unusual associations or presenting manifestations: pneumoconiosis masquerading as lung metastasis, Marfanoid habitus in MEN-2A and VHL spectrum disease, 1 with skull metastasis, and 2 cases with TKI-related complications in the form of glomerulonephritis and one patient displayed Marfanoid habitus with a RET mutation but without MEN2B or fibrillin gene mutation, while another developed bowel perforation secondary to lenvatinib therapy emphasizing diagnostic and therapeutic challenges and rare tumor associations...Management of MTC remains complex due to therapy-related complications and resistance. Molecular diagnostics enable better risk stratification and personalized care.

In this prematurely closed phase II study, 177Lu-Dotatate/capecitabine did not improve ORR or prolong PFS and OS in advanced NET patients compared to 177Lu-Dotatate alone and was associated with reduced QALYs.

Considering that SSTR expression is also present in various other tumors-including pheochromocytomas, paragangliomas, meningiomas, and medullary thyroid carcinomas-there is increasing interest in expanding the use of PRRT to other SSTR-positive malignancies. This review aimed to present evidence, explore ongoing clinical research, and highlight emerging directions for 177Lu-DOTATATE therapy beyond gastroenteropancreatic NETs.
