Evaluating synthetic CT from deformable registration in directed adaptive radiotherapy for head and neck cancer

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background and purposel Anatomical changes over the many weeks of radiotherapy for Head and Neck cancer patients can compromise the original treatment plan, potentially increase the risk of side effects and impact outcomes. It is difficult to decide, based on daily imaging alone, which patients will most benefit from adapted treatment plans ...

Synthetic CT artifacts in MR‐only brain radiotherapy: Clinical implementation experience

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Magnetic resonance imaging (MRI) provides superior soft tissue contrast compared with CT and is essential for delineation of targets and organs at risk in brain radiotherapy. Because CT is traditionally required for dose calculation in radiation therapy, synthetic CT (sCT) generation from MRI has enabled the development of MR‐only ...

Clinical implementation and performance evaluation of a motorized MR‐compatible OCTAVIUS 4D system for SBRT patient‐specific QA on a 1.5 T MR‐LINAC

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Magnetic resonance–guided radiotherapy using 1.5 T MR‐LINAC systems introduces specific constraints for patient‐specific quality assurance (PSQA), requiring MR‐compatible dosimetric devices capable of accurate three‐dimensional dose verification.

The Impact of the G8 Score on Survival Outcomes in Patients With Head and Neck Cancer Undergoing Concurrent Radiotherapy With Cetuximab due to Contraindications With Cisplatin

Cancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT Purpose Patients unable to receive cisplatin due to age, comorbidities, or reduced performance status are commonly treated with concurrent radiotherapy (RT) and cetuximab. This study evaluated the prognostic significance of the Geriatric 8 (G8) score and the Charlson Comorbidity Index (CCI) in predicting survival outcomes in this population ...

Different Pattern of Treatment Failure After Chemoradiation Between p16+ and p16− Patients Affected by Oropharyngeal Carcinoma

Head &Neck, Volume 48, Issue 8, Page 2048-2056, August 2026.
ABSTRACT Background Oropharyngeal cancer (OPC) exhibits distinct clinical behaviors according to HPV/p16 status and smoking exposure. While HPV‐positive OPC generally shows superior survival, differences in recurrence patterns remain unclear. Methods A retrospective multicenter analysis of 674 AJCC VII edition Stage III–IVa/b OPC patients treated with ...

Prognostic Value of Cranial Nerve Invasion in T4‐Stage Nasopharyngeal Carcinoma: A Retrospective Cohort Study With a Median Follow‐Up of 136 Months

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background The objective of this study was to evaluate the prognostic value of cranial nerve invasion (CNI) in T4‐stage nasopharyngeal carcinoma (NPC) patients with nonmetastatic. Methods We retrospectively analyzed 299 T4‐stage NPC patients with nonmetastatic disease in the Cancer Hospital of Shantou University Medical College.

A modality‐agnostic coronary artery habitat model for cardiac sparing in radiotherapy

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Emerging evidence suggests that the risk of cardiotoxicity increases with increased radiation dose to coronary arteries (CAs). However, robust tools to evaluate this increased burden for cancer patients are not available due to current limitations in imaging for radiotherapy treatment planning.

Photon minibeam‐based LATTICE radiotherapy for small and medium‐sized tumors: A dosimetric planning study

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Lattice radiotherapy (LRT) is a spatially fractionated technique that delivers three‐dimensional high‐dose vertices within tumors. However, conventional LRT is constrained by geometric limitations when applied to small and medium‐sized tumor volumes, primarily due to the large beam sizes that restrict optimal lattice pattern ...

HyperSight CBCT dose calculation accuracy for adaptive head and neck radiotherapy: Results from a prospective clinical trial

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Head and neck (H&N) patients frequently undergo anatomical changes such as weight loss and tumour shrinkage during treatment, requiring repeat imaging and replanning to maintain accurate dose delivery. On‐board cone‐beam CT (CBCT) systems could support these workflows, however they have historically been limited by reduced ...
