General Surgery, East Africa

Sub-Saharan Africa (SSA) remains significantly underrepresented in global cancer clinical trials, despite having the largest population of individuals of African descent, an essential demographic for ensuring diversity in clinical research. This study, developed from the 2024 African Organization for Research and Training in Cancer (AORTIC)-ASCO stakeholder meeting, addresses the critical need to involve SSA in cancer trials to improve global trial diversity and patient outcomes. Although globalization of trials has shifted research sites to regions like Eastern Europe and Asia, < 1% occur in Africa. This report highlights emerging solutions such as regional alliances, decentralized trial models, capacity-building initiatives, and public-private partnerships. The role of AORTIC and its Clinical Trial Special Interest Group in advancing training, infrastructure development, and international collaboration is discussed, with notable clinical trial networks, such as HypoAfrica, ARETTA, African Research Group for Oncology, and regional consortia, illustrating growing momentum and capability. This study advocates for a coordinated strategy to integrate SSA into global trials, ensuring more inclusive, effective, and equitable cancer treatment outcomes.

Faculty, Staff and Students Publications

Background: The preferred treatment for hypogonadism, testosterone replacement therapy (TRT), has a varying efficacy that is currently not fully understood. This observation may be explained by polymorphism of the androgen receptor (AR), a ligand-binding transcription factor whose polyglutamine tract length affects various health conditions and androgen sensitivity. It has been theorized that this polymorphism may also affect the severity of hypogonadism. This study sought to determine a correlation between hypogonadism severity, TRT efficacy, and number of CAG trinucleotide repeats in the AR gene.

Methods: One hundred sixty-two males presenting to a single institution with symptoms of hypogonadism were recruited for …

Objectives: Oral cavity head and neck squamous cell carcinoma (HNSCC) represents a major global health burden, with over 40,000 new cases annually in the United States and >500,000 worldwide. Despite advances in surgery, radiation therapy, chemotherapy, and immunotherapy, overall survival rates have remained largely stagnant over the past three decades, and over half of patients ultimately die from the disease. Although immune checkpoint inhibitors (ICIs) have improved outcomes for a subset of patients with recurrent or metastatic HNSCC, the majority gain limited benefit. Thus, novel therapeutic strategies that enhance responses to immunotherapy are urgently needed. The ATR-CHK1 signaling pathway has …

Eraso, Paul J. Dimuzio, Dario Pitocco, Massimo Massetti, Antonio Gasbarrini, Andrea Flex

Department of Surgery Faculty Papers

BACKGROUND: Patients with type 2 diabetes mellitus (T2DM) and chronic limb-threatening ischemia (CLTI) undergoing lower extremity revascularization (LER) face high risks of major adverse cardiovascular events (MACE) and major adverse limb events (MALE), despite guideline-directed lipid-lowering therapy. Apolipoprotein B100 (ApoB100), reflecting total atherogenic particle number, may identify residual risk beyond LDL-cholesterol (LDL-C). Therefore, we investigated whether baseline ApoB100 levels independently predict MACE and MALE beyond conventional risk factors in this high-risk population.

METHODS: In this prospective cohort study, 167 T2DM patients with CLTI undergoing LER were followed for 12 months with visits at 1, 3, 6, and 12 months post-procedure. …

Inactivating NOTCH1 mutations in head and neck squamous cell carcinoma (HNSCC) were described over a decade ago, suggesting a tumor suppressor function - unlike its oncogenic role in other tumors. Today, much debate persists regarding a putative oncogenic role in HNSCC as well, with reports that NOTCH1 signaling drives tumor growth and a cancer stem cell (CSC) phenotype. In this work, comprehensive experiments unequivocally demonstrate that NOTCH1 is a tumor suppressor in HNSCC regardless of mutation or activation status and that it reduces CSC frequency. We developed a signature of NOTCH1 activation showing the pathway is associated with very early …

Outcomes In Single Versus Two-Stage Surgical Stabilization Of Complex Bilateral Chest Wall Injury: A Single-Center Experience., Alexis A Schweibinz, Jaya S Varre, Anna Graham, William B Devoe

Surgery Articles

INTRODUCTION: Surgical stabilization of rib fractures (SSRF) continues to show benefit for severe chest wall injury (CWI) with improvement in morbidity and mortality following stabilization. Complex bilateral injuries pose a clinical and technical challenge. Currently, there is no formal recommendation for an approach to repair such injuries, whether that be bilateral SSRF within the index case or staged repair. We sought to describe our institutional experience with this subset of patients, identify factors that may influence the decision to pursue single- versus two-stage procedures, and assess the potential benefit of combined bilateral SSRF during the index operation.

METHODS: A retrospective, …

Objective: Obesity is a chronic disease linked to high mortality and morbidity after cardiac procedures, but its relationship to outcomes after total aortic arch replacement (TAR) remains unclear. We examined TAR data to determine whether obesity is associated with greater perioperative risk.

Methods: Among 787 TARs performed from 1990 to 2023, we excluded patients who lacked body mass index (BMI) data, had nonelective or nonstandard repairs, or were underweight (BMI < 18.5 kg/m2). The remaining 521 patients did not have obesity (18.5 ≤BMI < 30; n = 389) or did (BMI ≥30; n = 132). Patients with obesity were class 1 (30 ≤ BMI < 35), class 2 (35 ≤ BMI < 40), or class 3 (BMI ≥40). We compared preoperative and perioperative variables for BMI ≥30 (obesity) versus BMI < 30. Adverse events were operative mortality, persistent stroke, spinal cord deficit, and renal failure. We performed multivariable logistic regression and Kaplan-Meier survival analysis.

Results: Patients with obesity had greater rates of obstructive sleep apnea, transient spinal cord deficit, and acute renal dysfunction than patients with normal weight. During repair, the use of antegrade …

BACKGROUND: The risk of malignant transformation and recurrence of Sacrococcygeal Teratoma (SCT) is relatively high, while it is possibly lower in cases associated with Currarino Syndrome (CS). However, the existing literature gives contradictory results. We aimed to examine the risk of malignant transformation in a large cohort of SCT and CS patients.

METHODS: In a global retrospective cohort study, data of consecutive SCT patients and CS patients with presacral teratoma was obtained from 132 institutes in 62 countries. Malignant transformation, defined as malignancy at initial resection, malignant recurrence, or death due to malignancy was analysed for SCT and CS patients. …

INTRODUCTION: Revision anterior cruciate ligament (ACL) procedures are becoming more prevalent. Variable grafts for ACL reconstruction are available, including autograft, allograft, and synthetic graft options. Various augmentation techniques are also available and typically consist of synthetic material such as Artelon graft. This type of synthetic material has been used and shown to produce safe and reliable augmentation in ligament injuries. The purpose of this study was to describe our unique revision ACL reconstruction technique utilizing Artelon graft augmentation and report our short-term results.

MATERIALS AND METHODS: We retrospectively reviewed patients undergoing revision ACL reconstruction with Artelon graft augmentation, a Flexband …

Importance: Current lung cancer guidelines recommend lymph node sampling (LNS) with the 3 + 1 rule, which recommends station-based sampling with at least 3 N2 (mediastinal) and 1 N1 (hilar) nodal stations. Although there is oncologic benefit to rigorous LNS, potential negative impacts on surgical outcomes have not been well investigated. As adoption of the 3 + 1 rule increases given its formalization as guideline-concordant care, associations with adverse outcomes are crucial to characterize.

Objective: To evaluate whether satisfying the 3 + 1 rule is associated with increased postoperative complications.

Design, setting, and participants: This retrospective cohort study used the …
