Introduction: Chemotherapy-related cognitive impairment (CRCI) remains poorly understood in terms of the mechanisms of cognitive decline. Neural hyperactivity has been reported on average in cancer survivors, but it is unclear which patients demonstrate this neurophenotype, limiting precision medicine in this population.

Methods: We evaluated a retrospective sample of 80 breast cancer survivors and 80 non-cancer controls, aged 35-73, for which we had previously identified and validated three data-driven, biological subgroups (biotypes) of CRCI.

Background: Preventing central line-associated bloodstream infections (CLABSIs) remains a critical national focus for health care facilities. This notion is particularly true for patients undergoing hemodialysis (HD), where the associated mortality rates for HD-CLABSI range from 12% to 25%. Studies show that the use of central venous catheter (CVC) end caps coated with antiseptic agents, such as chlorhexidine gluconate (CHG) on HD-CVCs, can reduce the incidence of CLABSIs.

Article Synopsis
  • Researchers investigated how to improve serious illness conversations between clinicians and cancer patients at high risk of short-term mortality by using a machine learning model and trained care coaches.
  • In a study involving oncologists, patients with less than two years of predicted survival were prioritized for discussions, and automated reminders were sent to providers to document prognosis.
  • Results showed a significant increase in both prognosis and advance care planning documentation in visits where the intervention was applied compared to control visits, highlighting the effectiveness of the approach.

Purpose: Patients with well-differentiated, low-grade metastatic neuroendocrine neoplasms (NENs) usually have a long median survival and require complex, expensive care over many years at multidisciplinary centers. The cost burden for patients and institutions serves as a barrier to care. Understanding the drivers of these costs and whether intense monitoring adds value will help to optimize value-based care.

Background: Prophylactic growth-factor therapy with granulocyte colony-stimulating factor (G-CSF) reduces the risk of febrile neutropenia (FN) in patients with breast cancer initiating myelosuppressive chemotherapy. However, little is known about the protective benefit early in the chemotherapy cycle.

Methods: To assess the relationship between G-CSF prophylaxis and incidence of FN/infection in week 1 versus beyond week 1 of the first chemotherapy cycle, a retrospective study was conducted using Medicare claims from 2005 through 2020 among patients with breast cancer initiating high-risk chemotherapy.

When patients with cancer develop depression, it is often left untreated. We developed a prediction model for depression risk within the first month after starting cancer treatment using machine learning and Natural Language Processing (NLP) models. The LASSO logistic regression model based on structured data performed well, whereas the NLP model based on only clinician notes did poorly.

Purpose: Acute care use (ACU) is a major driver of oncologic costs and is penalized by a Centers for Medicare & Medicaid Services quality measure, OP-35. Targeted interventions reduce preventable ACU; however, identifying which patients might benefit remains challenging. Prior predictive models have made use of a limited subset of the data in the electronic health record (EHR).

This report from ASCO's International Quality Steering Group summarizes early learnings on how the COVID-19 pandemic and its stresses have disproportionately affected cancer care delivery and its delivery systems across the world. This article shares perspectives from eight different countries, including Austria, Brazil, Ghana, Honduras, Ireland, the Philippines, South Africa, and the United Arab Emirates, which provide insight to their unique issues, challenges, and barriers to quality improvement in cancer care during the pandemic. These perspectives shed light on some key recommendations applicable on a global scale and focus on access to care, importance of expanding and developing new treatments for both COVID-19 and cancer, access to telemedicine, collecting and using COVID-19 and cancer registry data, establishing measures and guidelines to further enhance quality of care, and expanding communication among governments, health care systems, and health care providers.

At the onset of the COVID-19 (coronavirus disease 2019) pandemic, telemedicine was rapidly implemented to protect patients and healthcare providers from infection. It is unlikely that care delivery will fully return to the pre-COVID form. Telemedicine offers many opportunities to improve care efficiency, accessibility, and patient outcomes, but many challenges exist related to technology interoperability, the digital divide, and usability.

Purpose: Large-scale analysis of real-world evidence is often limited to structured data fields that do not contain reliable information on recurrence status and disease sites. In this report, we describe a natural language processing (NLP) framework that uses data from free-text, unstructured reports to classify recurrence status and sites of recurrence for patients with breast and hepatocellular carcinomas (HCC).

Methods: Using two cohorts of breast cancer and HCC cases, we validated the ability of a previously developed NLP model to distinguish between no recurrence, local recurrence, and distant recurrence, based on clinician notes, radiology reports, and pathology reports compared with manual curation.
