Access to allogeneic and autologous hematopoietic stem cell transplantation (SCT) remains inadequate despite its curative potential across hematologic malignancies. In 2015, Hartford HealthCare (HHC) and the Memorial Sloan Kettering Cancer Center (MSK) established the Shared Care Model (SCM) with a primary aim of enhancing SCT access for HHC patients. The SCM comprises several components: an SCT-dedicated nurse-navigator, a health-information exchange for record sharing, telemedicine, and ongoing training of HHC clinicians in transplant patient selection and management.

Article Synopsis
  • COVID-19 severely impacts cancer patients, particularly those with metastatic cancer, and this study explored the relationship between cancer metastasis and COVID-19 outcomes.
  • Using data from the CCC19 registry, researchers analyzed over 10,000 cancer patients with COVID-19 to assess hospitalization rates and mortality based on the presence and site of metastasis.
  • Findings showed that patients with metastases had higher hospitalization rates (59% vs. 49%) and 30-day mortality (18% vs. 9%), with those having lung metastases experiencing the highest risk of death in that timeframe.

Article Synopsis
  • The COVID-19 pandemic has affected cancer patients differently across various regions in the U.S., showing that these patients are at a higher risk for severe COVID-19 complications.
  • This study tracked and analyzed COVID-19 outcomes among cancer patients diagnosed between March and November 2020 across different U.S. census divisions, focusing on factors that may influence their health outcomes.
  • Results indicated significant variability in 30-day mortality rates among cancer patients in different centers, ranging from 5.2% to 26.6%, suggesting that geographic location and healthcare center characteristics play a crucial role in these outcomes.

Anti-epidermal growth factor receptor (EGFR) antibodies and anti-programmed cell death 1 protein (PD-1) antibodies have been used separately to treat metastatic cutaneous squamous cell carcinoma (cSCC). While two anti-EGFR antibodies have similar clinical activity, cetuximab is administered weekly, whereas panitumumab is administered every two weeks. This report details findings using panitumumab in combination with anti-PD-1 antibody in patients with relapsed refractory cSCC.

Article Synopsis
  • A study investigated the impact of convalescent plasma treatment on 30-day mortality rates among hospitalized patients with hematologic cancers and COVID-19, as this group is known to have poor outcomes.
  • The research utilized a retrospective cohort design, analyzing data from the COVID-19 and Cancer Consortium registry, focusing on patients admitted between March 2020 and January 2021.
  • Results indicated that convalescent plasma treatment significantly improved 30-day mortality (HR, 0.60), with the benefit persisting even after accounting for potential confounding factors (HR, 0.52).

Background: Data on patients with COVID-19 who have cancer are lacking. Here we characterise the outcomes of a cohort of patients with cancer and COVID-19 and identify potential prognostic factors for mortality and severe illness.

Methods: In this cohort study, we collected de-identified data on patients with active or previous malignancy, aged 18 years and older, with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection from the USA, Canada, and Spain from the COVID-19 and Cancer Consortium (CCC19) database for whom baseline data were added between March 17 and April 16, 2020.

Purpose: Brain drain is the migration of educated and skilled individuals from a less developed region or country to a more economically established one. The Trump administration proposed a merit-based immigration plan. This article addresses its potential impact on health care delivery in low- and middle-income countries (LMICs) and their preparedness to deal with it.

Advances in the immunotherapy of cancer have prolonged survival for cancer patients, but the clinical and financial impact of treatments must be considered in determining the overall clinical utility and economic value of therapeutic agents. Quality-adjusted life years and incremental cost-effectiveness ratios are clinical and economic metrics that can be used to evaluate the value of immune checkpoint inhibitors. This Commentary provides perspective on the limitations, benefits, and potential enhancement of this approach to support value-based medicine.

Value-based health systems encompass a range of care-delivery models from small independent practices to large integrated delivery systems and academic medical centers. In addition, public and private payers, federal and state agencies, professional societies, and not-for-profit organizations collect and analyze data for quality and value improvement in health care-delivery outcomes. In this article, we review the multidimensional aspects of data collection, aggregation, analysis, and use for and by value-based health systems.

Next-generation sequencing (NGS)-based technology has lowered the cost of cancer testing for genomic alterations and is now commercially available from a growing number of diagnostic laboratories. However, laboratories vary in the methodologies underlying their tests, the types and numbers of genomic alterations covered by the test, and the clinical annotation of the sequencing findings. Determining the value of NGS tests is dependent on whether it is used to support clinical trials or as a part of routine clinical care at a time when both the investigational drug pipeline and the list of U.

At the ASCO Data Standards and Interoperability Summit held in May 2016, it was unanimously decided that four areas of current oncology clinical practice have serious, unmet health information technology needs. The following areas of need were identified: 1) omics and precision oncology, 2) advancing interoperability, 3) patient engagement, and 4) value-based oncology. To begin to address these issues, ASCO convened two complementary workshops: the Omics and Precision Oncology Workshop in October 2016 and the Advancing Interoperability Workshop in December 2016.

Cancer has become one of the leading causes of morbidity and mortality in low- and middle-income countries (LMICs), where 60% of the world's total new cases are diagnosed. The challenge for effective control of cancer is multifaceted. It mandates integration of effective cancer prevention, encouraging early detection, and utilization of resource-adapted therapeutic and supportive interventions.

Objective: Using electronic health records (EHRs) and biomolecular data, we sought to discover drug pairs with synergistic repurposing potential. EHRs provide real-world treatment and outcome patterns, while complementary biomolecular data, including disease-specific gene expression and drug-protein interactions, provide mechanistic understanding.

Method: We applied Group Lasso INTERaction NETwork (glinternet), an overlap group lasso penalty on a logistic regression model, with pairwise interactions to identify variables and interacting drug pairs associated with reduced 5-year mortality using EHRs of 9945 breast cancer patients.

Oncology patients often find themselves facing an incurable disease with limited treatment options and increasing patient fragility. The importance of patient preferences and values increases in shared decision making especially when the cost of cancer care is continuing its steep rise. As our understanding of cancer systems biology increases, we are justifiably optimistic about therapeutic improvements but recognize that this has complicated the traditional Food and Drug Administration approval of drug indications based on organ-specific cancer for a particular drug.

Purpose: The 21-gene recurrence score (RS) identifies patients with breast cancer who derive little benefit from chemotherapy; it may reduce unwarranted variability in the use of chemotherapy. We tested whether the use of RS seems to guide chemotherapy receipt across different cancer care settings.

Methods: We developed a retrospective cohort of patients with breast cancer by using electronic medical record data from Stanford University (hereafter University) and Palo Alto Medical Foundation (hereafter Community) linked with demographic and staging data from the California Cancer Registry and RS results from the testing laboratory (Genomic Health Inc.
