Abstract Background Volumetric‐modulated arc therapy (VMAT) represents a standard of care for head and neck cancer (HNC). However, treatment plan quality depends heavily on the planner's expertise, thereby challenging the standardization of treatment quality.

Online adaptive radiotherapy in stereotactic body radiotherapy for pancreatic cancer patients
Stereotactic radiation therapy (SBRT) has emerged as a promising treatment modality for locally advanced pancreatic cancer. The aim of this study is to assess the dosimetric efficacy of online adaptive radiotherapy (ART) in comparison to image-guided ...

Performance evaluation of a new type of commercial silicon detectors for photon beam dosimetry
Abstract Background Modern radiotherapy relies on advanced treatment techniques that utilize a large number of small fields, for which maintaining dosimetric accuracy is often challenging. Most vendors have introduced microdetectors suitable for small field dosimetry. Sun Nuclear has developed two silicon diodes with a sensitive volume of 0.35 mm3 that

Abstract Background Flattening filter‐free (FFF) beams are increasingly deployed for stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS). The Elekta Versa HD (VHD) and Varian TrueBeam (TB) are the two most widely used FFF‐capable platforms; however, no prior study has compared their 6 MV FFF commissioning parameters under fully ...

Abstract Background Cone‐beam computed tomography (CBCT) is widely used in image‐guided radiotherapy because it reflects the patient's anatomy immediately before treatment. However, CBCT images of the abdominal organs, including the pancreas, are often degraded by respiratory motion.

ABSTRACT Radiation therapy (RT) is a mainstay of treatment for a myriad of cancers, often utilized for tumors that are unable to be resected, as well as an adjunct to surgery and chemotherapy. Unfortunately, many cancers are resistant to RT‐induced damage and subsequent cell death.

A tailored non‐uniform PTV strategy (including PTVcrop and PTV_high/PTV_low) was used in SBRT for ultra‐central NSCLC to meet stringent OAR constraints. Notably, this SBRT strategy achieved favorable clinical outcomes, with an 84.6% 3‐year local control rate, a median PFS of 42.9 months. Additionally, treatment‐related toxicity was mild, with only 1.5%

Turning Cold Tumors Into Hot Tumors: Implications for Cancer Therapy
Barrier‐defined strategies for cold‐to‐hot tumor conversion. Cold tumors include immune‐desert and immune‐excluded states marked by poor antigen visibility, limited T‐cell priming, stromal or vascular exclusion, metabolic stress and suppressive immune programs.

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 ...

Abstract Background Tumor control probability (TCP) modeling for early‐stage non‐small cell lung cancer (NSCLC) is usually performed by one‐dimensional (1D) fitting that assumes error‐free dose and assigns all uncertainty to the local control (LC) axis.
