Abstract 3684: Socioeconomic and clinical predictors of survival in patients with squamous cell tonsillar cancer

Shama D. Karanth, Pamela Sandow, Mihika M. Shinde, Nimish R. Valvi et autres

Abstract Background: Tonsillar cancer represents a distinct and understudied subset of head and neck malignancies with rising incidence, largely driven by human papillomavirus (HPV), associated oropharyngeal cancer. Understanding the roles of clinical characteristics and socioeconomic factors is critical for optimizing early detection …

Neoadjuvant Therapy for Localized Pancreatic Cancer

Jordan A. McKean, Patrick W. Underwood, Abdul Qahar K. Yasinzai, Thomas J. George et autres

BACKGROUND/OBJECTIVES: Pancreatic ductal adenocarcinoma is an aggressive malignancy with poor long-term survival. While surgical resection followed by adjuvant chemotherapy remains the standard of care for resectable disease, a substantial proportion of patients fail to receive postoperative therapy. Neoadjuvant treatment has emerged as …

Neighborhood Disadvantage and Cardiovascular Mortality Among Colorectal Cancer Survivors

Nimish R. Valvi, Matthew R. Groenewold, Krista P. Terracina, Himanshi Verma et autres

Background: Cardiovascular disease (CVD) is a common cause of death among colorectal cancer (CRC) patients. We examined whether neighborhood disadvantage is associated with CVD mortality in CRC patients. Methods: Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) program for …

Alliance A022101/NRG-GI009: A pragmatic randomized phase III trial evaluating total ablative therapy for patients with limited metastatic colorectal cancer—Evaluating radiation, ablation, and surgery (ERASur).

Eric D. Miller, Kathryn Hitchcock, Qian Shi, Jesse G. Dixon et autres

TPS3634 Background: For patients with oligometastatic colorectal cancer (CRC), aggressive local therapy of isolated metastases, particularly in the liver, has been associated with long-term progression-free and overall survival (OS) primarily based on retrospective evidence. However, in patients with limited metastatic CRC that …

Impact of year-end holidays on delayed cancer diagnoses and survival implications: A population-based study.

Abdul Qahar Khan Yasinzai, Paul L. Crispen, Devika Das, Stephanie A. S. Staras et autres

e13793 Background: Timely diagnosis and treatment initiation are critical for optimizing cancer survival outcomes. However, periods of reduced healthcare accessibility and shifts in patients' routines, such as during holidays, may contribute to delays. This study aims to assess whether end-of-year holiday schedules …

Patient setup variation on Elekta Unity and its impact on adaptive planning

Erika Kollitz, Sheng‐Hsuan Sun, Kathryn Hitchcock, Alexandra De Leo et autres

PURPOSE: The unique design of the MR-linac may restrict the use of effective immobilization devices, resulting in significant patient setup variations (PSVs). The purpose of this study is to analyze the PSVs on the Elekta Unity system and investigate their impact on …

Paul B. Romesser, Eric D. Miller, Qian Shi, Jesse G. Dixon et autres

TPS309 Background: Patients with oligometastatic colorectal cancer (CRC) often experience long-term progression-free survival and overall survival (OS) following aggressive local treatment of isolated metastases, especially in the liver. However, the effectiveness of local ablative therapies, such as microwave ablation (MWA) and stereotactic …

Least significant change with repeat bioelectrical impedance analysis measurements in children with metabolic dysfunction–associated steatotic liver disease: A descriptive cohort study

Alexandria Speakman, Kathryn Hitchcock, Emily Romantic, Venancio Quiambao et autres

Abstract Background Bioelectrical impedance is used clinically to assess body composition. To determine true (rather than chance/measurement error) change in bioelectrical impedance analysis measurements over time, it is necessary to know their least significant change. Least significant change represents values exceeding the …
