Conference Presentation Abstracts

Purpose: To assess the efficiency improvement of SPArc compared to IMPT in proton clinical operation.Methods: A random clinical operation day at a proton therapy center with a two room system. Aa total of 10 Head & Neck cancer cases treated on Jan 6th, 2021were selected and SPArc plans were generated for all the cases with similar target coverage and dose constraints of organ at risk (OARs). 3% range uncertainties and 3mm setup uncertainties were applied for robust optimization. The log files of clinical IMPT were exported to calculate true treatment delivery time. The machine-specific delivery sequence model was utilized to …

Reliability Of Surgical Margin Labels Using 3d Radiographic Software, Heather Ross, Raphael Banoub, Md, Brian Swendseid, Md, Joseph Curry, Md

Phase 1

Introduction: Surgical resection is a primary treatment for head and neck cancers that improves prognosis and quality of life for patients. Margin assessment is a critical component in this process as positive margins are associated with poor clinical outcomes. However, there is a lack of consensus on how surgical margins should be labeled for accurate origin identification. The objective of this project is to determine the difference in interpretation of surgical margin labels between and within Thomas Jefferson otolaryngologists and pathologists.

Methods: Adults with head and neck cancer who underwent surgical resection were identified. Pre-operative head and neck CT DICOM …

Malnutrition is highly prevalent in patients with foregut tumors comprising head and neck (HNC) and esophageal (EC) cancers, negatively impacting outcomes. International evidence-based guidelines (EBGs) for nutrition care exist; however, translation of research evidence into practice commonly presents considerable challenges and consequently lags. This study aimed to describe and evaluate current international nutrition care practices compared with the best-available evidence for patients with foregut tumors who are at high risk of malnutrition. A multi-centre prospective cohort study enrolled 170 patients commencing treatment of curative intent for HNC (n = 119) or EC (n = 51) in 11 cancer …
