RESUMO

As clinical trials have become more complex, with increasing numbers of required procedures and clinic visits, gaining access to promising new treatments has become even more challenging for many individuals. To address these barriers, we implemented a financial reimbursement and outreach program designed to increase the number and diversity of participants in cancer clinical trials at centers in Dallas, Houston, and Philadelphia. As endorsed by U.S. Food and Drug Administration (FDA) and the Texas and Pennsylvania State Legislatures, the program provides financial reimbursement for non-clinical costs (e.g., travel, lodging) to patients on cancer clinical trials with household income up to 700% the Federal poverty rate. The research study described here, centered at the Dallas site, evaluates program impact by assessing (1) numbers and diversity of patients enrolled to cancer clinical trials before and after program implementation; (2) characteristics of patients offered participation in the program who do versus do not enroll; (3) characteristics of patients enrolled in the program who do versus do not complete the reimbursement process. To evaluate perceived barriers and facilitators of program participation, we will conduct semi-structured interviews and administer the Comprehensive Score for Financial Toxicity Patient Reported Outcome Measure (COST PROM) and the Short Assessment of Health Literacy (SAHL). This program will examine how reimbursement of non-clinical costs can improve access to cancer clinical trials, with the eventual goal of increasing trial enrollment, diversity, representativeness, and generalizability.

RESUMO

Pathological estimation of tumor necrosis after chemotherapy is essential for patients with osteosarcoma. This study reports the first fully automated tool to assess viable and necrotic tumor in osteosarcoma, employing advances in histopathology digitization and automated learning. We selected 40 digitized whole slide images representing the heterogeneity of osteosarcoma and chemotherapy response. With the goal of labeling the diverse regions of the digitized tissue into viable tumor, necrotic tumor, and non-tumor, we trained 13 machine-learning models and selected the top performing one (a Support Vector Machine) based on reported accuracy. We also developed a deep-learning architecture and trained it on the same data set. We computed the receiver-operator characteristic for discrimination of non-tumor from tumor followed by conditional discrimination of necrotic from viable tumor and found our models performing exceptionally well. We then used the trained models to identify regions of interest on image-tiles generated from test whole slide images. The classification output is visualized as a tumor-prediction map, displaying the extent of viable and necrotic tumor in the slide image. Thus, we lay the foundation for a complete tumor assessment pipeline from original histology images to tumor-prediction map generation. The proposed pipeline can also be adopted for other types of tumor.

RESUMO

The American Society of Pediatric Hematology/Oncology (ASPHO) recognized recent changes in medical practice and the potential impact on pediatric hematology-oncology (PHO) workforce. ASPHO surveyed society members and PHO Division Directors between 2010 and 2016 and studied PHO workforce data collected by the American Board of Pediatrics and the American Medical Association to characterize the current state of the PHO workforce. The analysis of this information has led to a comprehensive description of PHO physicians, professional activities, and workplace. It is important to continue to collect data to identify changes in composition and needs of the PHO workforce.

RESUMO

PURPOSE: The Accreditation Council for Graduate Medical Education (ACGME) has established communication as a core competency for physicians in training. However, data suggest that most pediatric residents perceive inadequate training in the delivery of bad news and the majority of former trainees in pediatric oncology received no formal training in the delivery of bad news during fellowship. The study examines communication training in ACGME accredited US pediatric hematology-oncology (PHO) fellowship programs. METHODS: An online survey was distributed to 315 PHO fellows in training via the American Society of Pediatric Hematology/Oncology (ASPHO) fellow email registry. Each fellow received an initial request to participate and 2 reminders, while participation was encouraged through a random incentive drawing. RESULTS: One hundred and ten fellows (35%) responded. Eighty percent of respondents perceived communication training to be important to fellow education, however only 32% reported receiving communication training (other than direct observation). The most common reported teaching method of fellowship communication training was formal lecture (42%). Twenty-three percent of respondents reported neither communication training nor frequent feedback on their communication skills from faculty observation. This same group was the least satisfied with their programs' approach to teaching communication (P < 0.001). CONCLUSIONS: There is limited communication training in PHO fellowships despite ACGME requirements and fellows' interest in this training. Didactic learning remains the most frequently described training method, yet educational theory identifies the limitation of didactic lectures alone. Communication training employing novel teaching methods and emphasizing communication challenges identified by fellows should be developed and evaluated.
