Computed tomography radiomics showed exploratory recurrence signals in mandibular osteoradionecrosis
In 24 surgically confirmed cases, three radiomic features differed nominally between pure osteoradionecrosis and osteoradionecrosis with recurrence.

High lactate dehydrogenase-5 and low lymphocyte infiltration identified higher relapse risk after prostate radiotherapy
Combined high lactate dehydrogenase-5 expression and low tumor-infiltrating lymphocyte density independently identified higher biochemical relapse risk after prostate radiotherapy.
Percussive ventilation enabled imaging and lung stereotactic ablative radiotherapy within one breath-hold
Three of four patients completed final imaging and lung stereotactic ablative radiotherapy within one assisted breath-hold, with only grade 1 adverse events.
Five-fraction partial breast irradiation with helical tomotherapy showed favorable dosimetry and mild toxicity
Five-fraction helical tomotherapy achieved favorable organ sparing, while the planning target volume-to-breast ratio was associated with higher ipsilateral breast dose.
Early stereotactic radiotherapy was associated with longer progression-free survival in pancreatic cancer
Adding early stereotactic body radiotherapy to neoadjuvant chemoimmunotherapy was associated with median progression-free survival of 12.5 versus 6.6 months.
Regional lymph node irradiation altered immune responses after sinonasal stereotactic radiotherapy in dogs
Regional lymph node irradiation was linked to attenuated local cytokine shifts and nodal damage and cell-death signatures after sinonasal stereotactic radiotherapy.
Oxygen ions produced greater pancreatic cancer cell killing than carbon ions and photons
Oxygen-ion irradiation showed higher biological effectiveness and more persistent DNA damage than carbon ions or photons in pancreatic cancer cells.
Split inhale–exhale planning reduced rib dose in lung stereotactic body radiotherapy
Splitting eight fractions between inhale and exhale breath-holds reduced maximum rib dose from 67.9 to 33.5 Gy without compromising target coverage.
Early diffusion changes precede brain lesions after proton therapy for low-grade glioma
Regional diffusion changes distinguished patients who developed contrast-enhancing brain lesions as early as six months after proton therapy.
Body composition adds little to radiotherapy toxicity prediction
Computed tomography-derived muscle measures ranked highly for toxicity and quality of life, but added little predictive value beyond established clinical factors.
Radiotherapy primes PDL1-targeted radionuclide therapy but splenic uptake limits efficacy
Radiotherapy increased tumor uptake of PDL1-targeted radionuclide therapy, while antibody co-dosing reduced splenic trapping and restored antitumor efficacy in mice.
Convergent 60 keV photons show cell-dependent biological effectiveness
Convergent 60 keV photons matched orthovoltage radiation and showed comparable or greater biological effectiveness than 6 MV photons, depending on cell type.
Dose de-escalation improved patient-reported outcomes in early p16-positive oropharyngeal cancer
Reducing radiotherapy from 70 Gy to 60 Gy was associated with better one-year swallowing outcomes and lower acute toxicity in selected patients.
Glutathione S-transferase mu 3 limits testicular injury after ultrahigh dose-rate irradiation
In mice, ultrahigh dose-rate X-rays caused less early testicular damage than conventional irradiation, with protection linked to ferroptosis suppression.
Risk-adapted esophagus sparing reduces dose with low severe esophagitis in lung cancer
Risk-adapted esophagus-sparing radiotherapy maintained target coverage, with grade 3 esophagitis in only 1.25% of high-risk patients.
