Purpose: Adolescent and young adult (AYA) patients with cancer frequently receive intensive measures at the end of life; many also express care goals that align with a palliative approach. We sought to understand the extent to which AYAs are referred to palliative care before death, the timing of referrals, and associations between referral timing and end-of-life care outcomes.

Methods: Review of electronic health data and medical records for 1,918 AYAs age 12-39 years who died after receiving care at one of the three sites between 2003 and 2019.

Importance: Adolescent and young adult (AYA) patients with advanced cancer often die in hospital settings. Data characterizing the degree to which this pattern of care is concordant with patient goals are sparse.

Objective: To evaluate the extent of concordance between the preferred and actual location of death among AYA patients with cancer.

Importance: Little is known about the nature of change in goals of care (GOC) over time among adolescents and younger adult (AYA) patients aged 12 to 39 years with cancer near the end of life. Understanding how GOC evolve may guide clinicians in supporting AYA patients in making end-of-life decisions.

Objective: To assess frequency, timing, and evolution of documented GOC among AYA patients with cancer in the last 90 days of life.

Poverty-exposed children with cancer are more likely to experience adverse outcomes. Supplemental Nutrition Assistance Program (SNAP) benefits improve food insecurity and child health outcomes, and could be used to mitigate disparities. We conducted a secondary analysis of parent-reported data collected in a frontline pediatric leukemia trial (NCT03020030) to assess SNAP eligibility (proxied by other means-tested program participation) and participation.

Clinical ethics consultation services (CECS) can be particularly complex in oncology, and widespread misconceptions exist about their nature. As a result, visibility and accessibility of information regarding CECS is critical. We investigated the availability and content of information regarding CECS on websites of NCI-designated comprehensive cancer centers and cancer centers (CCs).

Patient Reported Outcomes (PROs) are widely used in quality of life (QOL) studies, health outcomes research, and clinical trials. The importance of PRO has been advocated by health authorities. We propose this R shiny web application, PROpwr, that estimates power for two-arm clinical trials with PRO measures as endpoints using Item Response Theory (GRM: Graded Response Model) and simulations.

Importance: Greenhouse gas (GHG) emissions from health care are substantial and disproportionately harm persons with cancer. Emissions from a central component of oncology care, outpatient clinician visits, are not well described, nor are the reductions in emissions and human harms that could be obtained through decentralizing this aspect of cancer care (ie, telemedicine and local clinician care when possible).

Objective: To assess potential reductions in GHG emissions and downstream health harms associated with telemedicine and fully decentralized cancer care.

Article Synopsis
  • A study investigated how adolescents and young adults with cancer received different types of cancer treatments, such as chemotherapy, targeted therapy, and immunotherapy, in their last 90 days of life between 2009 and 2019.
  • Out of 1,836 patients, 35% received chemotherapy, while 24% got targeted therapy, 7% immunotherapy, and 5% investigational drugs, showing a trend toward increased use of these therapies over time.
  • Over 50% of the patients received at least one form of systemic cancer-directed therapy in their last three months, highlighting the need to align treatment decisions with the patients' preferences during advanced illness.

Inequitable uptake of novel therapies (NT) in non-cancer settings are known for patients with lower socioeconomic status (SES), People of Color (POC), and older adults. NT uptake equity in acute myeloid leukemia (AML) is not well known. We performed a retrospective cohort study (1/2014-8/2022) of the United States nationwide Flatiron Health electronic health record-derived, de-identified database.

Introduction: Dementia increases the risk of polypharmacy. Timely detection and optimal care can stabilize or delay the progression of dementia symptoms, which may in turn reduce polypharmacy. We aimed to evaluate the change in polypharmacy use among memory clinic patients living with dementia who participated in a dementia care program compared to those who did not.

Purpose: Adolescents and young adults (AYAs) with cancer receive high rates of medically intensive measures at the end of life. This study aimed to characterize the prevalence and timing of conversations about goals of care and advance care planning among AYAs at the end of life as one potential influence on care received.

Methods: This was a review of electronic health data and medical records for 1,929 AYAs age 12-39 years who died after receiving care at one of three sites between 2003 and 2019, including documented conversations about goals of care and advance care planning, and care received.

There is a paucity of data regarding the impact of liver fibrosis on patients with stage D heart failure (HF). We conducted a retrospective study (January 1, 2017 to December 12, 2020) in patients with stage D HF who underwent liver biopsy as part of their advanced HF therapy evaluation. Baseline characteristics and 1-year outcomes were compared between no- or mild-to-moderate-fibrosis (grade 0 to 2) and advanced-fibrosis (grade 3 to 4) groups.

Objectives: The number of publications of prospective surgical residents has steadily increased over the past decade as the emphasis on research output has become paramount. However, the reported data from the National Resident Matching Program (NRMP) does not discriminate amongst impact, author position, and region of matched residents. This study aimed to evaluate categorical general surgery postgraduate year 1 (PGY-1) residents' research productivity by programs' research impact and region of the United States and support the need for additional public data on research metrics of accepted applicants.

Facioscapulohumeral muscular dystrophy (FSHD) is one of the most prevalent muscular dystrophies characterized by considerable variability in severity, rates of progression and functional outcomes. Few studies follow FSHD cohorts long enough to understand predictors of disease progression and functional outcomes, creating gaps in our understanding, which impacts clinical care and the design of clinical trials. Efforts to identify molecularly targeted therapies create a need to better understand disease characteristics with predictive value to help refine clinical trial strategies and understand trial outcomes.

The primary goal for any clinical trial after it receives a funding notification is to receive regulatory approval and initiate the trial for recruitment. Every trial must go through documentation and regulatory process before it can start recruiting participants and collecting data; this initial process of review and approval is known as the study start-up process (SSU). We evaluated the average time taken for studies to receive approvals.

One measure of research productivity within the University of Kansas Cancer Center (KU Cancer Center) is peer-reviewed publications. Considerable effort goes into searching, capturing, reviewing, storing, and reporting cancer-relevant publications. Traditionally, the method of gathering relevant information to the publications is done manually.

We examined the relationship between the daily rate of change of cancer antigen 19-9 (CA19-9) over the first 90 days of treatment (DRC90) and the pretreatment levels of neutrophils, lymphocytes, and platelets with the overall survival (OS) and progression-free survival (PFS) in patients with stage IV pancreatic ductal adenocarcinoma (PDA) who received chemotherapy. We retrospectively evaluated 102 locally advanced and metastatic PDA patients treated at the University of Kansas Cancer Center (KUCC) between January 2011 and September 2019. We compared the ratio of the pretreatment absolute neutrophil count to the pretreatment absolute lymphocyte count (NLR) and the ratio between the pretreatment platelet count to the pretreatment absolute lymphocyte count (PLR) with the OS and PFS.

Background: An investigational pharmacy is responsible for all tasks related to receiving, storing, and dispensing of any investigational drugs. Traditional methods of inventory and protocol tracking on paper binders are very tedious and could be error-prone. To evaluate the utilization of the IDS to efficiently manage the inventory within an investigational Pharmacy.
