Article Synopsis
  • The study examines the effectiveness of ESTRO-EANO guidelines for RT-planning in glioblastomas using [F]DOPA-PET, comparing their target definition thresholds (1.6-1.8) with traditional biological-tumor-volume (BTV) thresholds derived from the striatum. !* -
  • An analysis of 50 glioma patients found that the striatum SUVmax threshold often resulted in smaller and less accurate tumor volumes, with significant discrepancies noted in many cases. !* -
  • The research concludes that the ESTRO-EANO thresholds for defining tumor volume are compatible with [F]DOPA-PET scans, while using the striatal SUV

Metastasis-directed therapy (MDT) has been tested in clinical trials as a treatment option for oligorecurrent prostate cancer (PCa). However, there is an ongoing debate regarding the impact of using different imaging techniques interchangeably for defining lesions and guiding MDT within clinical trials. We retrospectively identified oligorecurrent PCa patients who had 5 or fewer nodal, bone, or visceral metastases detected by choline or prostate-specific membrane antigen (PSMA) PET/CT and who underwent MDT stereotactic body radiotherapy with or without systemic therapy in 8 tertiary-level cancer centers.

Article Synopsis
  • The study aimed to validate the effectiveness of autoplanning in whole breast irradiation across various clinical practices and complex cases, involving 24 centers and 240 patients.
  • Results showed equivalent target dosimetry between autoplans and manually generated plans, with significant reductions in doses to critical organs, leading to clinician preferences for autoplans in more cases.
  • The findings suggest that while autoplanning reduces the manual workload and improves outcomes, adjustments may be needed in some cases to increase clinician satisfaction with the automated plans.

Novelty in total body irradiation (TBI) as part of pre-transplant conditioning regimens lacked until recently, despite the developments in the field of allogeneic stem cell transplants. Long-term toxicities have been one of the major concerns associated with TBI in this setting, although the impact of TBI is not so easy to discriminate from that of chemotherapy, especially in the adult population. More recently, lower-intensity TBI and different approaches to irradiation (namely, total marrow irradiation, TMI, and total marrow and lymphoid irradiation, TMLI) were implemented to keep the benefits of irradiation and limit potential harm.

Brain metastases (BMs) represent the most frequent metastatic event in the course of lung cancer patients, occurring in approximately 50% of patients with non-small-cell lung cancer (NSCLC) and in up to 70% in patients with small-cell lung cancer (SCLC). Thus far, many advances have been made in the diagnostic and therapeutic procedures, allowing improvements in the prognosis of these patients. The modern approach relies on the integration of several factors, such as accurate histological and molecular profiling, comprehensive assessment of clinical parameters and precise definition of the extent of intracranial and extracranial disease involvement.
