Postoperative high-dose RT achieved strong local control in lacrimal gland adenoid cystic carcinoma
After surgery plus 66–70 Gy, only one of six patients recurred locally, while half developed distant metastases.

VMAT
Simulation-free VMAT preserved delivered dose for palliative bone radiotherapy
Diagnostic CT-based VMAT preserved PTV D95 at 99.6% of planned dose across 30 palliative bone RT plans.
VMAT with a custom 3D bolus treated nasal BCC with low early toxicity
Seven patients completed 60 Gy with no recurrences, grade ≥3 skin toxicity, fibrosis, cartilage necrosis, or nasal contour deformation at early follow-up.
Postoperative VMAT was feasible after aortic-allograft tracheal reconstruction for adenoid cystic carcinoma
Four patients completed 54 Gy after airway reconstruction without graft-related toxicity or local recurrence during early follow-up.
Single-arc VMAT remained comparable to double-arc planning with bilateral hip prostheses
Double-arc VMAT was slightly more robust, but single-arc planning achieved clinically comparable dosimetry with simulated bilateral hip prostheses.
Jaw-partitioned VMAT increased peak-to-valley dose separation in spatially fractionated radiotherapy
Jaw-partitioned VMAT improved dose gradients and peak-to-valley separation in GRID and lattice plans, but approximately doubled monitor units.
Bladder-only radiotherapy substantially irradiated adjacent pelvic nodes regardless of IMRT technique
Obturator nodes received about 75% of the prescribed bladder dose incidentally, with similar regional exposure from VMAT and fixed-field IMRT.
Aperture-restricted VMAT substantially reduced heart dose during left-sided regional nodal irradiation
Restricting deep VMAT apertures reduced heart and ipsilateral lung exposure across three linacs while maintaining comprehensive breast and nodal coverage.
VMAT exposed less circulating blood than IMRT in glioma simulations
VMAT exposed less circulating blood than IMRT, but modeled immune-cell depletion differed by only one percentage point after 30 fractions.
VMAT-based pediatric TBI achieved organ sparing with acceptable early clinical outcomes
VMAT-TBI achieved 96.6% mean PTV D95 while keeping mean lung and kidney doses below 9 Gy.
3D-printed oral stents were associated with less toxicity after nasopharyngeal radiotherapy
Patient-specific stents improved tongue and parotid stability and were associated with substantially less hearing loss, dysphagia and dysgeusia.
uTPS produced deliverable Halcyon VMAT plans comparable with Eclipse
uTPS generated Halcyon VMAT plans with generally comparable dosimetry to Eclipse and greater than 97% gamma passing rates.
VMAT lattice radiotherapy produced 65% median shrinkage in bulky hepatocellular carcinoma
Twelve VMAT lattice courses produced 65% median tumor shrinkage and no local progression during short follow-up in bulky hepatocellular carcinoma.
VMAT lattice radiotherapy on standard linacs provided early palliation in bulky tumors
In eight bulky tumor sites, flattening-filter VMAT lattice radiotherapy produced 75% symptom relief with no grade 3 or higher acute toxicity.
AI-assisted VMAT planning shortened workflow but required manual hotspot correction
AI-assisted planning cut average planning time from about two hours to 30 minutes, but three of 12 plans required manual hotspot correction.
