Peptide receptor radionuclide therapy (PRRT) is an effective treatment for both oncological and hormone control and is a widely accepted standard of care treatment for patients with neuroendocrine neoplasms (NEN). Its use is anticipated to increase significantly, and this demands accurate tools and paradigms to assess treatment response post PRRT. This article outlines the current role and future developments of anatomical, molecular imaging and biomarkers for response assessment to PRRT, highlighting the challenges and provides perspectives for the need to focus on a multimodality, multidisciplinary and individualised approach for patients with this complex heterogeneous disease.

Digital twins (DTs) are emerging tools for simulating and optimizing therapeutic protocols in personalized nuclear medicine. In this paper, we present a modular pipeline for constructing patient-specific DTs aimed at assessing and improving dosimetry protocols in PRRT such as therapy. The pipeline integrates three components: (i) an anatomical DT, generated by registering patient CT scans with an anthropomorphic model; (ii) a functional DT, based on a physiologically-based pharmacokinetic (PBPK) model created in SimBiology; and (iii) a virtual clinical trial module using GATE to simulate particle transport, image simulation, and absorbed dose distribution.

This case report is focused on a patient (a 32-year-old previously healthy man) with a femoral bone tissue tumor. The case underscores the diagnostic complexity of Telangiectatic Osteosarcoma (TOS) with Aneurysmal Bone Cystic (ABC) lesion and the importance of maintaining special immunohistochemical markers for differential diagnosis between low-grade osteosarcoma, primary ABC, and suspected TOS, which is a true mimicker of ABC. On the other hand, this presentation describes some molecular rearrangements seen in ABC.

Vertebrates exhibit remarkable morphological diversity, with the head representing an exceptionally complex anatomical structure shaped by adaptations to feeding ecology, brain size, and sensory organ specialization. Proper fusion of facial prominences and the coordinated growth of the skull and brain are essential for normal craniofacial development in vertebrates, including humans. Disruptions in these processes, whether due to gene mutations or external factors, can result in craniofacial malformations.

Background And Purpose: To date, no consensus guidelines have been published that systematically guide delineation of primary and nodal Clinical Target Volumes (CTVs) in patients who require post-operative radiotherapy (PORT) for mucosal Head and Neck squamous cell carcinoma (HNSCC). As a result, significant individual, institutional and national variation exists in the way that CTVs are delineated in the post-operative setting, leading to considerable heterogeneity in radiotherapy treatment.
Methods: A multi-disciplinary group of experts convened by the European Society for Radiotherapy and Oncology (ESTRO) set-out principles for the multi-disciplinary management of oral cavity squamous cell carcinoma (OCSCC).
