Racial Differences in Survival Among Advanced-stage Non-small-Cell Lung Cancer Patients Who Received Immunotherapy: An Analysis of the US National Cancer Database (NCDB)

Race-inclusive and equitable access to immune checkpoint inhibitor therapy: What are the biggest hurdles?

A real‐world data analysis evaluating the clinical outcomes of consolidation durvalumab after concurrent chemoradiation in Black versus non‐Black patients with unresectable stage III non–small cell lung cancer demonstrates that there was no overall difference in survival or toxicity between the two groups. The study addresses the important issue of race‐ and ethnicity‐related disparities in clinical trial accruals that limit the generalizability of the results across the patient population. Larger multi‐institutional prospective studies evaluating racially underrepresented populations are warranted to evaluate the contribution of individual factors, optimize treatment strategies, and narrow the disparities in cancer care.

Impact of Race on Outcomes of Advanced Stage Non-Small Cell Lung Cancer Patients Receiving Immunotherapy

BACKGROUND

The impact of race in advanced stage non-small cell lung cancer (NSCLC) patients treated with immune checkpoint inhibitors (ICIs) is conflicting. Our study sought to examine racial disparities in time to treatment initiation (TTI), overall survival (OS), and progression-free survival (PFS) using a population that was almost equally black and white.

METHODS

This was a retrospective cohort study of stage IV NSCLC patients > 18 years receiving immunotherapy at our center between 2014 and 2021. Kaplan-Meier curves and the multivariate Cox proportional hazards model determined the predictors of OS and PFS. Analyses were undertaken using IBM PSAW (SPSS v.28).

RESULTS

Out of 194 patients who met the inclusion criteria, 42.3% were black (n = 82). In the multivariate analysis, there was no difference in PFS (HR: 0.96; 95% CI: 0.66,1.40; p = 0.846) or OS (HR: 0.99; 95% CI: 0.66, 1.48; p = 0.966). No difference in treatment selection was observed between white and black patients (p = 0.363), nor was there a difference observed in median time to overall treatment initiation (p = 0.201).

CONCLUSIONS

No difference was observed in OS and PFS in black and white patients. Black patients' reception of timelier immunotherapy was an unanticipated finding. Future studies are necessary to better understand how race impacts patient outcomes.

A biopsychosocial model to understand racial disparities in the era of cancer immunotherapy

The approval and wide uptake of immune checkpoint inhibitors (ICIs) in oncology practice raise the concerns of possibly worsened racial disparities in cancer treatment due to biological and psychosocial reasons. We propose a multilevel biopsychosocial model to understand the opportunities and challenges to racial disparities in the era of cancer immunotherapy.

Navigating financial toxicity in patients with cancer: A multidisciplinary management approach

Approximately one-half of individuals with cancer face personal economic burdens associated with the disease and its treatment, a problem known as financial toxicity (FT). FT more frequently affects socioeconomically vulnerable individuals and leads to subsequent adverse economic and health outcomes. Whereas multilevel systemic factors at the policy, payer, and provider levels drive FT, there are also accompanying intervenable patient-level factors that exacerbate FT in the setting of clinical care delivery. The primary strategy to intervene on FT at the patient level is financial navigation. Financial navigation uses comprehensive assessment of patients' risk factors for FT, guidance toward support resources, and referrals to assist patient financial needs during cancer care. Social workers or nurse navigators most frequently lead financial navigation. Oncologists and clinical provider teams are multidisciplinary partners who can support optimal FT management in the context of their clinical roles. Oncologists and clinical provider teams can proactively assess patient concerns about the financial hardship and employment effects of disease and treatment. They can respond by streamlining clinical treatment and care delivery planning and incorporating FT concerns into comprehensive goals of care discussions and coordinated symptom and psychosocial care. By understanding how age and life stage, socioeconomic, and cultural factors modify FT trajectory, oncologists and multidisciplinary health care teams can be engaged and informative in patient-centered, tailored FT management. The case presentations in this report provide a practical context to summarize authors' recommendations for patient-level FT management, supported by a review of key supporting evidence and a discussion of challenges to mitigating FT in oncology care.
