Purpose: Structural racism (SR) is a potential driver of health disparities, but research quantifying its impacts on cancer outcomes has been limited. We aimed to develop a multidimensional county-level SR measure and to examine the association of SR with breast cancer (BC) treatment delays among Black and White patients.

Methods: The cohort included 32,095 individuals from the North Carolina Central Cancer Registry with stage I to III BC diagnosed between 2004 and 2017 and linked to multipayer insurance claims from the Cancer Information and Population Health Resource.

Article Synopsis
  • * A total of 9,822 patients were analyzed, revealing that by 2018, nearly half of the second-line therapies (2LT) included newer agents, and overall survival improved when treatments were initiated in later years.
  • * While improvements in survival were noted, the costs of 2LT increased significantly, especially for regimens with newer agents, with costs rising markedly post-2012, indicating a growing financial burden in RRMM treatment.

Purpose: Financial toxicity is a contributor to the psychosocial burden of cancer care. There is no consensus measure of financial toxicity; however, recent studies have adopted the Comprehensive Score for Financial Toxicity (COST). Despite its growing popularity, data on the responsiveness to change of the COST instrument are lacking.

Purpose: Multiple myeloma (MM) is a prevalent hematologic malignancy in older adults, who often experience physical disability, increased health care usage, and reduced treatment tolerance. Home health (HH) services are frequently used by this group, but the relationship between disability, HH use, and MM treatment receipt is unclear. This study examines the connections between disability, treatment receipt, and survival outcomes in older adults with newly diagnosed MM using a nationwide data set.

Background: Inequities in guideline-concordant treatment receipt contribute to worse survival in Black patients with breast cancer. Inequity-reduction interventions (eg, navigation, bias training, tracking dashboards) can close such treatment gaps. We simulated the population-level impact of statewide implementation of inequity-reduction interventions on racial breast cancer inequities in North Carolina.

Background: Patients with blood cancer experience serious physical and emotional symptoms throughout their cancer journey.

Objective: Building on previous work, we aimed to develop an app designed to help patients with multiple myeloma and chronic lymphocytic leukemia self-manage symptoms and test it for acceptability and preliminary efficacy.

Methods: We developed our Blood Cancer Coach app with input from clinicians and patients.

Background: Treatment delays affect breast cancer survival and constitute poor-quality care. Black patients experience more treatment delay, but the relationship of geography to these disparities is poorly understood.

Methods: We studied a population-based, retrospective, observational cohort of patients with breast cancer in North Carolina between 2004 and 2017 from the Cancer Information and Population Health Resource, which links cancer registry and sociodemographic data to multipayer insurance claims.

Background: The plasma cell disorders (PCDs), multiple myeloma (MM), and light-chain amyloidosis (AL) are disproportionately diseases of older adults, whose care may be complicated by frailty associated with advancing age. We sought to evaluate the prevalence of functional deficits and symptoms in a cohort of persons with PCDs and associations of demographic, disease-related, functional, and psychosocial measures with quality of life (QoL).

Patients And Methods: Adults with PCDs were recruited into an observational registry in 2018-2020.

Background: The purpose of this manuscript is to describe health-related quality of life (HRQoL) outcomes in a United States (US)-based sample of multiple myeloma (MM) patients and identify characteristics associated with poor HRQoL.

Patients And Methods: MM patients identified through the Tumor Registry of a Southeastern US medical center were mailed surveys assessing patient characteristics and HRQoL outcomes. HRQoL outcomes were measured using PROMIS short form instruments which included measures of global health (global physical health and global mental health), physical function, and ability to participate in social roles and activities (social function).

This study describes the prevalence and persistence of fatigue among a cohort of long-term non-Hodgkin lymphoma (NHL) survivors. Mailed surveys assessed quality-of-life including fatigue (SF-36) at baseline and five years. Logistic regression was used to identify factors associated with prevalence of fatigue at baseline and persistence of fatigue across timepoints.

Purpose: To explore the ways in which multiple myeloma affects an individual's life in the modern treatment era.

Participants & Setting: 15 individuals with multiple myeloma and 10 clinicians were recruited from two academic medical centers in the southeastern United States.

Methodologic Approach: Semistructured interviews were conducted with individuals with multiple myeloma and clinicians to explore the effect of a multiple myeloma diagnosis and treatment on individuals' lives.

Purpose: Patients with relapsed and/or refractory multiple myeloma (RRMM) are living longer due in part to changing treatment patterns. It is important to understand how changing treatment patterns affect patients' lives beyond extending survival. Research suggests that direct patient report is the best way to capture information on how patients feel and function in response to their disease and its treatment.

Patients with cancer suffer greatly. Rehabilitation helps them suffer less, and yet very few patients with cancer get rehabilitation services of any kind. Oncology nurses are well positioned to see the toll that cancer and its treatment take on patients and to facilitate appropriate supportive care, including rehabilitation.
