Inducing Accelerated Lung Toxicity In Mice Using A Partial Arc Sbrt Technique, Andrew Gerry, Charita Kunta, Noelle Francois, Tiziana Deangelis, Anuradha Shastri, Nicole Simone, Reza Taleei

Department of Radiation Oncology Posters

Background

• Radiation-induced pulmonary fibrosis (RIPF) is a frequent outcome of thoracic radiation therapy, constraining safe tumor radiation dosage. Various animal models, such as mice, rats, and pigs, have been devised to study RIPF
• Current methods for inducing lung fibrosis in mice involve whole lung irradiation with doses between 2-20 Gy. These methods used fixed anterior and posterior (AP/PA) x-ray beams at 0º and 180º with analysis typically commencing 24 to 52 weeks post-radiation
• Current methods are unrepresentative of modern radiation therapy techniques and are limited by the associated long latency of RIPF

Influence Of Pretreatment Magnetic Resonance Imaging On Local Therapy Decisions For Intermediate-Risk Prostate Cancer Patients, Christian Skowronski, Andrew Shanholtzer, Brent Yelton, Muayad Almahariq, Daniel Krauss

Prostate cancer has the third highest incidence rate and is the second leading cause of cancer death for men in the United States. Magnetic resonance imaging (MRI) provides superior soft tissue delineation serving as a valuable tool for both diagnosis and treatment planning. With minimal data regarding utility on diagnosis and treatment planning for intermediate-risk prostate cancer, the National Comprehensive Cancer Network’s guidelines indicate MRI as optional in intermediate-risk prostate cancer evaluation. This project aims to elucidate whether MRI affects radiation treatment decisions for intermediate-risk prostate cancer.

Outcomes Of Locally Advanced Lung Cancer Patients Treated With 60 Gy Vs. 70 Gy, Batoul Nasser, Muyad Almahariq, Inga Grills

Posters

The standard form of treatment for locally advanced lung cancer is to prescribe the conventional dose of 60 Gy radiation therapy (RT) concurrently with chemotherapy. However, five-year overall survival is still less than 20%. These outcomes remain poor due to both distant and local regional recurrence. The literature suggests that local regional control and overall survival is strongly associated with doses of radiotherapy that are higher than 60 Gy. However, when escalating radiation dose was prescribed exceeding 70 Gy, the overall survival rates plateaued. The primary goal of this study is to determine if there is a marked difference in …

Dose To The Left Anterior Descending Artery Correlates With Cardiac Events After Irradiation For Breast Cancer, Brittany Silverman, Andrew Zureick, Vincent Grzywacz, Muayad Almahariq, Aleksander Vayntraub, Joshua Dilworth

Posters

Although global heart dose has been associated with late cardiac toxic effects in patients who received radiation therapy for breast cancer, data detailing the clinical significance of cardiac substructure dosimetry are limited. We investigated whether dose to the left anterior descending artery (LAD) correlates with adverse cardiac events.

Tumor Locations Impact On Cardiac Toxicity In Women That Received Partial Breast Irradiation, Sara Diltz, Muayad Almahariq, Joshua Dilworth

Posters

Accelerated partial breast irradiation (APBI) is an appropriate modality for select women with low-risk breast cancer. While APBI delivers radiation dose to a smaller volume of breast tissue compared to whole breast irradiation, dose to the heart and coronary vessels may be relatively high, depending on the proximity of the treatment device to these structures. The primary goal of this study is to determine if the risk of adverse cardiac events depends on tumor location in women receiving APBI.

High Dose Rate Brachytherapy Monotherapy Versus External Beam Radiotherapy With Hdr Brachytherapy Boost For Unfavorable Intermediate Prostate Cancer Patients, Doyle Lang, Benjamin Willen, Daniel J. Krauss, Sirisha R. Nandalur

Posters

Prostate cancer is the most common male malignancy by incidence in the world. Treatment differs by the patient’s risk stratification. For the treatment of unfavorable intermediate-risk prostate cancer, external beam radiotherapy with high-dose-rate brachytherapy boost was the accepted treatment but high-dose-rate brachytherapy as monotherapy has been proposed as a potentially viable treatment option. External beam radiotherapy treatment involves shooting high-energy photons or particle radiation through normal healthy tissue to hit the tumor directly. High-dose-rate brachytherapy involves inserting radioactive seeds into the tumor. Studies are needed to compare toxicity profiles and relative outcomes between the two treatment options.

Imaging-Based Modules For Musculoskeletal Anatomy & Pathology In Preclinical Medical Education, Ameen Suhrawardy, Tarek Almsaddi, Sarah Fried, Sayf Al-Katib, Drew Moore, Malli Barremkala

Posters

Many medical students report a lack of adequate orthopedic and musculoskeletal (MSK) teaching in the preclinical medical curriculum. As gross anatomy is emphasized in pre-clinical education, students may feel a disconnect from clinical anatomy proficiency. This project assesses the efficacy of a preclinical image-based module to teach MSK anatomy and pathology concepts to preclinical medical students.

Impact Of Structured Reporting Template On The Quality Of Hrct Radiology Reports For Interstitial Lung Disease, Han G. Ngo, Girish B. Nair, Sayf Al-Katib

This QI study compared the completeness of HRCT radiology reports before and after the implementation of a disease-specific structured reporting template for suspected cases of interstitial lung disease (ILD).
