Owen D, Harmsen W, Ahmed S, Petersen I, Haddock M, Ma D, et al.
Pract Radiat Oncol
. 2024 Dec;
PMID: 39725127
Objectives: Spatially fractionated radiation therapy (SFRT) intentionally delivers a heterogeneous dose distribution characterized by alternating regions of high and low doses throughout a tumor. This modality may enhance response to...

Brachytherapy
. 2024 Oct;
23(6):676-686.
PMID: 39368901
Purpose: To design, construct, and evaluate a system for image-guided placement of brachytherapy applicators using electromagnetic tracking (EMT) technology for improved procedure quality and efficiency. The system, named EMVision, provides...

Curr Oncol
. 2024 Sep;
31(9):5384-5398.
PMID: 39330026
Background: Liposarcoma, one of the most prevalent sarcoma histologies, is recognized for its tendency for extra-pulmonary metastases. While oligometastatic cardiac disease is rarely reported, it poses a unique challenge as...

J Natl Cancer Inst
. 2024 Sep;
117(1):103-111.
PMID: 39254630
Background: NRG Oncology NSABP B-39/RTOG 0413 compared whole-breast irradiation (WBI) to accelerated partial-breast irradiation (APBI). APBI was not equivalent to WBI in local tumor control. Secondary outcome was quality of...

Adv Radiat Oncol
. 2024 Apr;
9(6):101485.
PMID: 38681890
Purpose: Myxofibrosarcoma (MFS) is a subtype of soft tissue sarcoma with a highly infiltrative growth pattern that leads to a higher risk of inadvertent positive surgical margins and local relapse....

Adv Radiat Oncol
. 2024 Mar;
9(3):101401.
PMID: 38495033
Purpose: Spatially fractionated radiation therapy (SFRT) is a recognized technique for enhancing tumor response in radioresistant and bulky tumors. We analyzed clinical and treatment outcomes in patients with bone and...
