Shoulder Arthroplasty Evolution: Comparing Reverse, Anatomic, And Hemiarthroplasty Trends And Outcomes In Key Demographics At A High-Volume Institution, James Fuchs Gannon, Mitchell Thomas Pfennig, Anthony Arveschoug, Betina Bremer Hinckel, J Michael Wiater, Leonardo M. Cavinatto

Conference Presentation Abstracts

The field of shoulder arthroplasty has changed markedly since the inception of the reverse total shoulder arthroplasty (RTSA) in 2004. With yearly gains of 32%, the RTSA now encompasses the largest portion of shoulder arthroplasty procedures. In contrast, the anatomic total shoulder arthroplasty (ATSA) and hemiarthroplasty (HA) have steadied or decreased in usage. Some have offered several explanations for these trends, such as expanding indications for the RTSA, in particular for pathologies traditionally treated with ATSA such as glenohumeral arthritis with an intact rotator cuff and no major bone loss/deformity. Others have cited superior postoperative outcomes of the RTSA over …

Effect Of Vitamin E Enhanced Highly Cross-Linked Polyethylene On Wear Rate And Particle Debris In Anatomic Total Shoulder Arthroplasty: A Biomechanical Comparison To Ultrahigh-Molecular-Weight Polyethylene, Adam Khan, Andrew Jawa, Matthew J. Smith, J Michael Wiater, Derek J. Cuff, Anand M. Murthi, Luke Stanford Austin

Conference Presentation Abstracts

INTRODUCTION: Particle-induced osteolysis resulting from polyethylene wear remains a source of implant failure in anatomic total shoulder designs. Modern polyethylene components are irradiated in an oxygen-free environment to induce polyethylene cross-linking, but an unfortunate byproduct of this process is free radical production. Melting or heat annealing is one method of reducing free radicals but can compromise the component’s mechanical properties. The antioxidant, Vitamin E, has been introduced as an alternative adjuvant to neutralize free radicals. Specifically, in anatomic shoulder arthroplasty with a ceramic head component, the vitamin E-enhanced polyethylene showed improved wear compared to the conventional highly-cross linked polyethylene. This …

Background: Pediatric molecular imaging requires a balance between administering an activity that will yield sufficient diagnostic image quality while maintaining patient radiation exposure at acceptable levels. In current clinical practice, this balance is arrived at by the current North American Consensus Guidelines in which patient weight is used to recommend the administered activity (AA).

Purpose: We have previously demonstrated that girth (waist circumference at the level of the kidneys) is better at equalizing image quality than patient weight for pediatric Tc-99m DMSA renal function imaging. However, the correlation between image quality (IQ), AA, and patient girth has not been rigorously …

Introduction

Genomic profiling is performed in patients with advanced or metastatic cancer, in order to direct cancer treatment, often sequencing tumor-only, without a matched germline comparator. However, because many of the genes analyzed on tumor profiling overlap with those known to be associated with hereditary cancer predisposition syndromes (HCPS), tumor-only profiling can unknowingly uncover germline pathogenic (P) and likely pathogenic variants (LPV). In this study, we evaluated the number of patients with P/LPVs identified in BRCA1 and BRCA2 (BRCA1/2) via tumor-only profiling, then determined the germline testing outcomes for those patients.

Methods

A retrospective chart review was performed …

Building on our prior work, we prospectively evaluated panobinostat and gemcitabine/busulfan/melphalan (GemBuMel) with ASCT in this population. Patients aged 18-65 years with relapsed/refractory or high-risk myeloma and adequate end-organ function were eligible. Treatment included panobinostat (20 mg/day, days -9 to -2) and GemBuMel (days -8 to -2). Patients were enrolled in 1st (ASCT-1) or 2nd ASCT (ASCT-2) cohorts. We compared their outcomes with all our other concurrent ASCT patients who met eligibility criteria but received melphalan or BuMel off study, matched for age, prior therapy lines, high-risk cytogenetics, and response …

Background & aims: There is a knowledge gap in understanding mechanisms of resistance to fibroblast growth factor receptor (FGFR) inhibitors (FGFRi) and a need for novel therapeutic strategies to overcome it. We investigated mechanisms of acquired resistance to FGFRi in patients with FGFR2-fusion-positive cholangiocarcinoma (CCA).

Methods: A retrospective analysis of patients who received FGFRi therapy and underwent tumor and/or cell-free DNA analysis, before and after treatment, was performed. Longitudinal circulating tumor DNA samples from a cohort of patients in the phase I trial of futibatinib (NCT02052778) were assessed. FGFR2-BICC1 fusion cell lines were developed and secondary acquired resistance …

OBJECTIVES: Cervical cancer has markedly declined due to widespread use of screening, but Hispanic women continue to bear a disproportionate amount of the cervical cancer burden due to under-screening. Previous studies have explored barriers to screening but have failed to identify targetable facilitators in this group. We aimed to assess facilitators to cervical cancer screening among a predominantly urban, Hispanic population who presented to a no-cost, community-based clinic.

METHODS: Patients completed demographic and health information, a validated social determinants of health (SDOH) screen, and a self-reported facilitators survey on factors which enabled them to present to clinic. Descriptive statistics were …

The detection of measurable residual disease (MRD) is the strongest predictor of relapse in acute lymphoblastic leukemia (ALL). Using inotuzumab ozogamicin in the setting of MRD may improve outcomes. Patients with ALL in first complete remission (CR1) or beyond (CR2+) with MRD ≥ 1 × 10-4 were enrolled in this phase 2 trial. Inotuzumab was administered at 0.6 mg/m2 on day 1 and 0.3 mg/m2 on day 8 of cycle 1, then at 0.3 mg/m2 on days 1 and 8 of cycles 2-6. Twenty-six consecutive patients with a median age of 46 years (range, 19-70 years) were treated. Nineteen (73%) …
