RESUMO
PURPOSE: Treatment-related pancreatitis (TRP) is a serious complication occurring in children with acute lymphoblastic leukemia (ALL). Those affected are at high risk for severe organ toxicity and treatment delays that can impact outcomes. TRP is associated with asparaginase, a standard therapeutic agent in childhood ALL. Native American ancestry, older age, high-risk leukemia, and increased use of asparaginase are linked to pancreatitis risk. However, dedicated genetic studies evaluating pancreatitis in childhood ALL include few Hispanics. Thus, the genetic basis for higher risk of pancreatitis among Hispanic children with ALL remains unknown. METHODS: Cases of children with ALL treated in from 1994 through 2013 were reviewed and identified 14, all Hispanic, who developed pancreatitis related to asparaginase therapy. Forty-six controls consisting of Hispanic children treated on the same regimens without pancreatitis were selected for comparison. Total DNA isolated from whole blood was used for targeted DNA sequencing of 23 selected genes, including genes associated with pancreatitis without ALL and genes involved in asparagine metabolism. RESULTS: Non-synonymous polymorphisms and frameshift deletions were detected in 15 genes. Most children with TRP had variants in ABAT, ASNS, and CFTR. Notably, children with TRP harbored many more CFTR variants (71.4%) compared with controls (39.1%). Among these, V470M (rs213950) was most frequent (OR 4.27, p = 0.025). CONCLUSIONS: This is the first study of genetic factors in treatment-related pancreatitis in Hispanic children with ALL. Identifying correlative variants in ethnically vulnerable populations may improve screening to identify which patients with ALL are at greatest risk for pancreatitis.

Despite the recognized need for clinical nurses to engage in the conduct of research, little is known about their research experiences. This article describes the experiences of nurses who delivered the communication intervention in a behavioral oncology clinical trial for parents of adolescents and young adults (AYAs) with cancer. A qualitative thematic analysis was conducted of nurse interveners' (NIs') reflections on their experiences delivering the communication intervention. Ten data-generating questions were developed to guide NIs' reflections. Twelve NIs responded via verbal discussions. Six of these also provided written responses. Overall, nurses' experiences as interveners were powerful and positive, and included time and space to be fully present with patients and families. Nurse interveners identified barriers to their involvement in research related to time constraints, administrative support, physical space to privately conduct the intervention, and difficulties maintaining expertise with the intervention. The importance of ongoing collaboration between nurses, unit staff, leaders, and study teams was corroborated. An unexpected finding was the importance of reflective clinical research.
