Resection And Reconstruction Of Ewing Sarcoma Of The Cuboid Utilizing Vascularized Fibular Autograft: A Case Report, Brandon Cunha, Alexandre Arkader

Rowan-Virtua Research Day

Ewing Sarcoma (EWS) rarely presents in the bones of the foot, and particularly in the cuboid, making it an exceedingly rare occurrence. We present the case of a 7-year-old female diagnosed with EWS of the right cuboid, detailing the management and outcomes of this rare presentation. The patient, now almost 5 years post-initial local control, exhibits restored foot function, a normalized gait, and no evidence of disease recurrence. This case underscores the potential for preserving lower extremity function and improving postoperative quality of life in rare presentations of EWS through innovative reconstruction strategies.

The circadian system, a vital temporal regulator influencing physiological processes, has implications for cancer development and treatment response. Our study assessed circadian timing’s impact on whole-brain radiotherapy outcomes in brain metastases for personalized cancer therapy insights. The aim of the study was to evaluate circadian influence on radiation treatment timing and its correlation with clinical outcomes and to identify patient populations benefiting from interventions synchronizing circadian rhythms, considering subgroup differences and potential disparities. An IRB-approved retrospective analysis of 237 patients undergoing whole-brain radiotherapy for brain metastases (2017–2021), receiving over 80% of treatments in the morning or afternoon, was performed. Survival …

Flash Radiation Ultra-High Dose Rate Radiation With Potential For Sensitization By Platinum, Abigail A. Jaczkowski, Stephen Brown Ph.D.

Medical Student Research Symposium

External beam radiation therapy, a cornerstone in cancer treatment for 50% of patients, poses challenges due to its toxicity to both cancer and healthy cells. Seeking to mitigate side effects, the emerging FLASH radiation technology employs ultra-high dose rates, promising quicker treatments with reduced impact on surrounding normal tissue. Platinum, recognized as a radiation sensitizer, enhances the effectiveness of radiation therapy by increasing sensitization at higher energy levels through pair-production.

This study explores the hypothesis that Cisplatin, a platinum-based chemotherapy agent, will exhibit a synergistic effect when combined with FLASH radiation. Using A549 cells from non-small cell lung cancer, the …
