Moving Beyond the Momentum: Innovative Approaches to Clinical Trial Implementation.

Despite efforts to enhance enrollment and the merger of national cooperative groups, < 5% of patients with cancer will enroll into a clinical trial. Additionally, clinical trials are affected by a lack of diversity inclusive of minority patients, rural residents, or low-income individuals. COVID-19 further exacerbated known barriers of reduced physician-patient interaction, physician availability, trial activation and enrollment, financial resources, and capacity for conducting research. Based on the cumulative insight of academic and community clinical researchers, we have created a white paper identifying existing challenges in clinical trial conduct and have provided specific recommendations of sustainable modifications to improve efficiency in the activation and conduct of clinical trials with an overarching goal of providing improved access and care to our patients with cancer.

Severe first infusion reaction related to cetuximab in cancer patients in Arkansas.

INTRODUCTION: Cetuximab, a chimeric monoclonal antibody, is a commonly used anticancer drug that prevents binding of epidermal growth factor to epidermal growth factor receptor. It has been widely used in a variety of cancers since its initial approval by the FDA in 2004. Despite its efficacy, it has met with some genuine concerns especially regarding the anaphylactoid reactions occurring after first infusions. Cetuximab-related first infusion reaction has been found to be much more prevalent in the Southeastern United States with several studies from the southern United States supporting it. The purpose of our study was to determine the rate of first infusion reaction in the state of Arkansas and the factors that could predispose to first infusion reaction. METHODS AND RESULTS: We performed a retrospective chart review of consecutive patients who received cetuximab between January 2004 and December 2016 at the University of Arkansas for Medical Sciences. We included a total of 220 patients in our analysis out of which 32 (14.5%) developed cetuximab-related first infusion reaction. There was a statistically significant increased risk in males versus females (18.2% vs. 8.4%, P = 0.045) and trend toward significance for the difference between Caucasians and Blacks (16.5% vs. 7.1%, P = 0.054). CONCLUSION: There is increased incidence of cetuximab-related first infusion reaction in Arkansas which is much higher than the national average but comparable to the incidence in other neighboring states in the Southeastern United States. This increased incidence tends to cluster in Caucasian males. Safer alternatives should be preferred for treatment of cancers particularly in the Southeastern United States whenever possible.

Integrating Collaborative Learning and Competition in a Hematology/Oncology Training Program.

New educational methods and structures to improve medical education are needed to face the challenge of an exponential increase and complexity of medical knowledge. Collaborative learning has been increasingly used in education, but its use in medical training programs is in its infancy, and its impact is still unknown; the role of competition in education is more controversial. We introduced these pedagogical methods to the hematology/oncology fellowship program at the University of Arkansas for Medical Sciences to improve attendance and performance at didactic activities and different educational outcomes. One year after the adoption of these methods, the fellowship program has reached many of the expected goals from this intervention without the negative consequences of competition observed in younger learners. The most important conclusion of this project is that collaboration and cross-generational team work provide a healthy and effective learning environment and competition may not add further benefit. Analysis, interpretation, and discussion of our experience are provided. This study was approved by the University of Arkansas for Medical Sciences IRB as a low risk educational intervention not requiring a consent form.

High Relative Expression of Pannexin 3 (PANX3) in an Axillary Sweat Gland Carcinoma With Osteosarcomatous Transformation.

Primary cutaneous sweat gland carcinomas (SGCs) are rare tumors that commonly involve axillae, have a high local recurrence rate, and rarely show sarcomatoid transformation. A 68-year-old man presented with rapid enlargement of a previously stable, asymptomatic pea-sized nodule in the left axilla. Initial excision (with positive surgical margins) at another institution showed characteristic histologic features of a high-grade osteosarcoma and molecular analysis using a 92-gene real-time quantitative reverse transcription-polymerase chain reaction assay confirmed a diagnosis of osteosarcoma with 96% certainty. Notably, the molecular assay demonstrated consistently high relative expression of pannexin 3 (PANX3), a gene involved in normal osteoblast differentiation which, when highly expressed, strongly predicts osteosarcoma per the assay's algorithm. However, on further histologic review, the tumor also contained focal cystic areas, nests, and ducts composed of malignant epithelial cells reminiscent of SGC; these areas directly transitioned into the osteosarcomatous component and were strongly positive for pancytokeratin, CK7, and p63. Within 2 weeks, the lesion recurred and grew rapidly, prompting complete resection, histologic sections of which showed high-grade osteosarcoma without residual epithelial elements. This is the fifth report, to our knowledge, of osteosarcomatous transformation in a SGC, and the only report to date including molecular data. This case demonstrates that osteosarcoma arising from a SGC has a similar molecular profile to de novo primary osteosarcoma of bone. It also emphasizes the importance of histopathologic findings as the established diagnostic gold standard and the need to interpret molecular results within the clinical context.
