Background: Although racially and ethnically minoritized populations are less likely to participate in cancer trials, it is unknown whether social determinants of health (SDOH) explain these inequities. Here we identify SDOH factors that contribute to racial and ethnic inequities in clinical trial participation among patients with 22 common cancers.

Methods: This retrospective cohort study used electronic health record data (2011-2023) linked to neighborhood (US Census tract) data from multiple sources.

Importance: There is increasing recognition from regulatory agencies that racial and ethnic representation in clinical trials is inadequate and linked to health inequities. The extent of racial inequities in clinical trial participation is unclear because prior studies have synthesized enrollment data from published trials, which often do not report participant race and ethnicity.

Objective: To evaluate racial and ethnic inequities in oncology clinical trial participation in a contemporary cohort of patients with cancer before and during the COVID-19 pandemic.

Regulatory agencies are increasingly considering real-world evidence (RWE) to support label expansions of approved medicines. We conducted a comparative effectiveness study to emulate a proposed randomized trial of romiplostim vs. standard-of-care (SOC) therapy among patients with recently diagnosed (≤12 months) immune thrombocytopenia (ITP), that could support expansion of the romiplostim label.

Background: Patients with immune thrombocytopenia (ITP) are at risk of bleeding and, paradoxically, thromboembolic events (TEEs), irrespective of thrombocytopenia. The risk of thrombosis is increased by advanced age, obesity, and prothrombotic comorbidities: cancer, hyperlipidemia, diabetes, hypertension, coronary artery disease, and chronic kidney disease, among others. Certain ITP treatments further increase the risk of TEE, especially splenectomy and thrombopoietin receptor agonists.

Background: Inflation-adjusted cancer costs in the United States have increased 40% in the last decade, leading to increasing financial burden on both payers and patients. Patients under 65 show substantial increases in utilization of expensive targeted therapy anticancer agents; however, patients aged 65+ account for the majority of new malignancies. Utilization and cost trends for these emerging agents have not been examined in detail in the Medicare population.

Purpose: Patients with cancer are at risk for substantial treatment-related costs; however, little is known about patients' willingness to sacrifice to receive cancer care and how their attitudes and burden may change with time.

Patients And Methods: We conducted a longitudinal survey of insured patients with solid tumor cancers receiving chemotherapy or hormonal therapy. Patients were surveyed at two time points about their willingness to make financial sacrifices and their actual sacrifices, including out-of-pocket costs.

Rectal adenocarcinoma is an important cause of cancer-related deaths worldwide, and key anatomic differences between the rectum and the colon have significant implications for management of rectal cancer, especially in the curative setting. For stage II and III rectal cancers, combined chemoradiotherapy offers the lowest rates of local and distant relapse, and is delivered neoadjuvantly to improve tolerability and optimize surgical outcomes, particularly when sphincter-sparing surgery is an endpoint. We review both pivotal trial data that has shaped the current standard of care, fluoropyrimidine-based chemoradiotherapy, while also presenting results from more recent studies, which aim to outperform this standard.
