Advanced-Stage Melanoma At Presentation Following The Peak Of The Pandemic: A Covid-19 Cancer Canary In A Coal Mine, Ryan Lamm, Md, Walker Lyons, Md, Winnie So, Rn, Alliric I. Willis, Md, Facs, Msph

Department of Surgery Faculty Papers

Background: For melanoma patients, timely identification and tumor thickness are directly correlated with outcomes. COVID-19 impacted both patients' ability and desire to see physicians. We sought to identify whether the pandemic correlated with changes in melanoma thickness at presentation and subsequent treatment timeline.

Methods: Retrospective chart review was performed on patients who underwent surgery for melanoma in an academic center surgical oncology practice from May 2019 to September 2021. Patients were split into two cohorts: "pre-pandemic" from May 2019 to May 2020 and "pandemic," after May 2020, representing when these patients received their initial diagnostic biopsy. Demographic and melanoma-specific variables …

Non-alcoholic steatohepatitis (NASH)-related hepatocellular carcinoma (HCC) has become the second leading cause of HCC-related liver transplantation in the United States. This study investigated post-transplant recurrence and survival for patients transplanted for NASH-related HCC compared to non-NASH HCC etiologies. Retrospective review of the United Network for Organ Sharing (UNOS) Organ Procurement and Transplantation Network (OPTN) database identified 7,461 patients with HCC—1,405 with underlying NASH and 6,086 with non-NASH underlying diseases. After propensity score matching (PSM) to account for patient- and tumor-related confounders 1,175 remained in each group. Primary outcomes assessed were recurrence rate and recurrence-free survival. Recurrent malignancy at 5 years …

Socioeconomic Status And Gastric Cancer Surgical Outcomes: A National Cancer Database Study., Ryan Lamm, D Brock Hewitt, Michael Li, Adam C Powell, Adam C Berger

Department of Surgery Faculty Papers

INTRODUCTION: Gastric cancer (GC) is the third leading cause of cancer-related death worldwide. Surgical resection is the gold standard of treatment. In the United States, race and socioeconomic status are associated with the diagnosis of GC; however, no studies have examined these as independent risk factors for surgical outcomes. Our study sought to investigate socioeconomic factors and GC surgical outcomes using a national cancer registry.

METHODS: GC patients between 2004 and 2016 were identified using the National Cancer Database. Univariate and multivariate logistic regression was used to analyze associations between socioeconomic factors and 30-d mortality, 90-d mortality, and unplanned readmission …
