Factors Associated With Rectal Spacer Use in Prostate Cancer Patients Receiving Radiation Therapy

Cancer Medicine, Volume 15, Issue 5, May 2026.
ABSTRACT Background/Objective Prostate cancer is a leading cause of cancer‐related death among men in the United States. However, the influence of demographic, socioeconomic, regional, and treatment‐related factors on rectal spacer use among men treated with radiation therapy remains largely unexplored in the literature.

The Clinical Relevance of Lymph Node Ratio for Post‐Mastectomy Radiotherapy in Triple‐Negative Breast Cancer: A Real‐World Analysis With Propensity Score Matching Using SEER Database

Cancer Medicine, Volume 15, Issue 5, May 2026.
ABSTRACT Background To define the role of post‐mastectomy radiotherapy (PMRT) in triple‐negative breast cancer (TNBC), employing lymph node ratio (LNR, ratio of positive over excised lymph nodes) to offer personalized treatment strategies for this aggressively behaving cancer type. Methods The study included a total of 6474 women diagnosed with T1‐4 N1‐

Battery‐Free UV‐Dose Detector via Defect‐Engineered Ca2SnO4:RE (RE = Sm3+, Pr3+) Oxide Phosphors

Carbon Neutralization, Volume 5, Issue 3, May 2026.
Sm3+/Pr3+‐doped Ca2SnO4 (CSO:RE) phosphors exhibit orange/deep‐red 4f–4 f emissions and defect‐related luminescence. LPL, TL, and OSL measurements reveal thermally/optically addressable traps, with OSL signals retained after 504 h dark storage. Embedded in a polymer matrix, CSO:RE enables battery‐free UV‐dose logging under sunlight with optical readout,

Boost Approaches in Patients Undergoing Postoperative Radiotherapy

Journal of Surgical Oncology, Volume 133, Issue 6, Page 773-784, May 2026.
ABSTRACT The use of breast conservation surgery for early‐stage breast cancer is common, and adjuvant radiotherapy is often recommended to reduce the risk of ipsilateral breast tumor recurrence. Historical trials have used sequential boost techniques with favorable outcomes with reduction in local recurrence and acceptable cosmetic outcomes.

A preclinical setup for spatially fractionated radiation therapy with electrons

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Spatially fractionated radiation therapy (SFRT) has therapeutic potential as a priming therapy which boosts tumor control. However, the optimal delivery and spatial fractionation parameters have not been deciphered and the mechanisms at play are not yet fully understood.

Cenozoic Time Constraints on the Evolution of a Gleysol‐Ferralsol‐Podzol Toposequence, Northwest Amazon Basin, Brazil

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT Deciphering the time milestones of clay formation is crucial for modeling the evolution of major geological systems near the Earth's surface. In the present study, kaolinite samples collected along four vertical profiles within a Gleysol‐Ferralsol‐Podzol soil toposequence near São Gabriel da Cachoeira, NW Amazon Basin (Brazil) are dated using ...
