Radiation treatment has been the cornerstone in cancer management. However, long term treatment-related morbidity always accompanies tumor control which has significant impact on quality of life of the patient who has survived the cancer. Spatially fractionated radiation has the potential to achieve both cure and to avoid dreaded long term sequelae. The first ever randomized study of mini-beam radiation treatment (MBRT) of canine brain tumor has clearly shown the ability to achieve this goal. Dogs have gyrencephalic brains functionally akin to human brain. We here report long term follow-up and final outcome of the dogs, revealing both tumor control and side effects on normal brain. The results augur potential for conducting human studies with MBRT.

Background: Salvage surgery (SS) is one of the best treatment options for recurrent oropharyngeal squamous cell carcinoma (OPSCC) after prior definitive radiation.
Methods: A Medline literature search of articles on open (OSS) and transoral robotic surgery (TORS) for the treatment of recurrent OPSCC was performed. Surgical, functional, and oncological outcomes were analyzed and compared.

We focused on a paper titled "Radiation with immunotherapy may be a double-edged sword-how can we learn from recent negative clinical trials?", which was published in recently. Herein, we initially provided three complementary viewpoints from biological perspectives involved in the dynamic alterations of the tumor microenvironment, which may contribute to a more comprehensive understanding of the superiority of stereotactic body radiation therapy (SBRT).

Cell senescence is a state of stable proliferation arrest characterized by morphological changes and high senescence-associated β-galactosidase (SA-β-gal) activity. Inducing senescence in cancer cells is beneficial for cancer therapy due to proliferation arrest, however, the mechanisms underlying this process remain insufficiently understood. Therefore, the present study investigated the mechanisms of radiation-induced cellular senescence in A549 human lung cancer cells, focusing on the DNA damage response and cell cycle regulation.

Purpose: To evaluate the impact of an optimized online adaptive radiation therapy workflow on physician involvement.
Methods And Materials: Data from a prospective phase 2 trial involving 34 prostate cancer patients treated with cone beam computed tomography (CBCT)-based online adaptive radiation therapy (62 Gy in 20 fractions) were analyzed. Manual interventions were required for 2 steps in the workflow: radiation therapy technologist review and adjustment of automatically segmented organs, guiding target segmentation, so-called "influencer," while physicians reviewed and refined the targets.

Digital twins (DTs) are emerging tools for simulating and optimizing therapeutic protocols in personalized nuclear medicine. In this paper, we present a modular pipeline for constructing patient-specific DTs aimed at assessing and improving dosimetry protocols in PRRT such as therapy. The pipeline integrates three components: (i) an anatomical DT, generated by registering patient CT scans with an anthropomorphic model; (ii) a functional DT, based on a physiologically-based pharmacokinetic (PBPK) model created in SimBiology; and (iii) a virtual clinical trial module using GATE to simulate particle transport, image simulation, and absorbed dose distribution.
