OBJECTIVE: Neuroblastoma has one of the lowest survival rates of all childhood cancers, despite the use of intensive treatment regimens. Preclinical models of neuroblastoma are essential for testing new multimodality protocols, including those that involve...
Over 60% of cancer patients worldwide will receive radiotherapy as a part of their overall treatment plan. Recently, stereotactic body radiation therapy (SBRT) has been recognized as a favorable treatment option for those cancer types that remain inoperable. SBRT administers very high doses of radiation in a small number of fractions, and has been shown to achieve 3-year control rates of roughly 90% in stage 1 NSCLC’s.
Pancreatic ductal adenocarcinoma (PDAC) is characteristically radioresistant tumor type with roughly 25% of patients requiring radiotherapy as form of treatment. With poor clinical outcomes (5-year survival of 7%) new and innovative treatments are required to improve patient outcome. Due to the lack of an effective treatment in the clinic for PDAC, translational research yielding clinically relevant results is necessary to develop new and effective treatment.
Purpose To implement clinical stereotactic body radiation therapy (SBRT) using a small animal radiation research platform (SARRP) in a genetically engineered mouse model of lung cancer. Methods and Materials A murine model of multinodular Kras-driven spontaneous lung...
Purpose: Local tumor growth is a major cause of morbidity and mortality in nearly 30% of patients with pancreatic ductal adenocarcinoma (PDAC). Radiotherapy (RT) is commonly used for local disease control in PDAC, but efficacy is limited. We studied the impact of...
A new paper titled “Bioluminescence Tomography – Guided Radiation Therapy for Preclinical Research” has been published in the International Journal of Radiation Oncology. The Xstrahl SARRP system was used for the research conducted in the published paper, the study details how Bioluminescence has enabled researchers to precisely visualize their tumors in vivo.
In preclinical radiation research, it is challenging to localize soft tissue targets based on cone beam computed tomography (CBCT) guidance. As a more effective method to localize soft tissue targets, we developed an online bioluminescence tomography (BLT) system for small-animal radiation research platform (SARRP). We demonstrated BLT-guided radiation therapy and validated targeting accuracy based on a newly developed reconstruction algorithm.

Computed tomography (CT) is the standard imaging modality in radiation therapy treatment planning (RTP). However, magnetic resonance (MR) imaging provides superior soft tissue contrast, increasing the precision of target volume selection. We present MR-only based RTP...
