Utility of tumor-informed circulating tumor DNA in the clinical management of gastrointestinal malignancies.

Background: Gastrointestinal (GI) malignancies represent a heterogeneous group of diseases. Traditional tumor markers, though part of standard-of-care, lack sensitivity and specificity. Tumor-informed circulating tumor DNA (ctDNA) assay-based molecular residual disease assessment as well as recurrence and treatment response monitoring can serve as a robust tool in patients with wide range of GI malignancies and ethnicities.

Challenges in Pathology Specimen Processing in the New Era of Precision Medicine.

Context.—: Precision therapies for patients with driver mutations can offer deep and durable responses that correlate with diagnosis, metastasis prognosis, and improvement in survival. The use of such targeted therapies will continue to increase, pushing us to change our traditional approaches.

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.
