Severe brainstem necrosis followed standard proton CSI in 22q11.2 deletion syndrome
A patient with 22q11.2 deletion developed refractory brainstem necrosis nine months after guideline-concordant proton craniospinal irradiation.

Voxel-wise cumulative EQD2 review prompted reoptimization in 25.5% of proton reirradiation courses and exposed frequent registration problems.
Modern proton techniques reduce cardiopulmonary dose and can control skin exposure, while randomized cardiac and cancer-control endpoints remain pending.
CT-guided iodine-125 implantation achieved 60.7% one-year response without grade ≥3 pneumonitis in patients with severe pulmonary dysfunction.
Responsive rectal tumors showed greater cytotoxic immune infiltration, while poor responders were enriched for stromal, EMT and oncogenic pathways.
Five-year survival was 74.9% versus 90.2% for patients living in food-insecure versus other areas despite similar cancer treatment.
Adding parotid–target overlap shape features improved moderate-to-severe xerostomia prediction from AUC 0.66 to 0.78.
External validation achieved AUC 0.986, while modeled risk-adapted surveillance reduced visits by 90.0–98.5% and identified every observed failure.
Recurrent NPC with GTV LETd99 ≥39.4 keV/μm had 94.4% versus 65.3% two-year local control after carbon-ion reirradiation.
A 2D antiscatter grid reduced soft-tissue CT-number error from 169 to 38 HU at unchanged imaging dose.
Three Quad Shot cycles caused limited high-grade toxicity, no systemic-therapy delays and frequent thoracic symptom improvement.
Adding SNP data increased arm-lymphedema prediction AUC from 0.78 to 0.93 in the multicenter REQUITE cohort.
A circulation-based model predicted post-SBRT lymphocyte trajectories and linked a higher predicted lymphocyte nadir with better survival.
Daily surface changes shifted proton beam depth by up to 17.4 mm and reduced accumulated target D99 by up to 24.3%.
Protons, SRS and IMRT produced 98% overall local control without grade 3–5 toxicity in 54 paragangliomas.
