Abstract
PURPOSE OF REVIEW Lung cancer remains the leading cause of cancer mortality worldwide. Health disparities have long been noted in lung cancer incidence and survival and persist across the continuum of care. Understanding the gaps in care that arise from disparities in lung cancer risk, screening, treatment, and survivorship are essential to guiding efforts to achieve equitable care. RECENT FINDINGS Recent literature continues to show that Black people, women, and people who experience socioeconomic disadvantage or live in rural areas experience disparities throughout the spectrum of lung cancer care. Contributing factors include structural racism, lower education level and health literacy, insurance type, healthcare facility accessibility, inhaled carcinogen exposure, and unmet social needs. Promising strategies to improve lung cancer care equity include policy to reduce exposure to tobacco smoke and harmful pollutants, more inclusive lung cancer screening eligibility criteria, improved access and patient navigation in lung cancer screening, diagnosis and treatment, more deliberate offering of appropriate surgical and medical treatments, and improved availability of survivorship and palliative care. SUMMARY Given ongoing disparities in lung cancer care, research to determine best practices for narrowing these gaps and to guide policy change are an essential focus of future lung cancer research.

Roberts EK, Luo L, Mondul AM, Banerjee M, Veenstra CM, Mariotto AB, Schipper MJ, He K, Taylor JMG, Brouwer AF. Time-varying associations of patient and tumor characteristics with cancer survival: an analysis of SEER data across 14 cancer sites, 2004-2017. Cancer Causes Control 2024:10.1007/s10552-024-01888-y. [PMID: 38811511 DOI: 10.1007/s10552-024-01888-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Accepted: 05/13/2024] [Indexed: 05/31/2024]
Abstract
PURPOSE Surveillance, Epidemiology, and End Results (SEER) cancer registries provides information about survival duration and cause of death for cancer patients. Baseline demographic and tumor characteristics such as age, sex, race, year of diagnosis, and tumor stage can inform the expected survival time of patients, but their associations with survival may not be constant over the post-diagnosis period. METHODS Using SEER data, we examined if there were time-varying associations of patient and tumor characteristics on survival, and we assessed how these relationships differed across 14 cancer sites. Standard Cox proportional hazards models were extended to allow for time-varying associations and incorporated into a competing-risks framework, separately modeling cancer-specific and other-cause deaths. For each cancer site and for each of the five factors, we estimated the relative hazard ratio and absolute hazard over time in the presence of competing risks. RESULTS Our comprehensive consideration of patient and tumor characteristics when estimating time-varying hazards showed that the associations of age, tumor stage at diagnosis, and race/ethnicity with risk of death (cancer-specific and other-cause) change over time for many cancers; characteristics of sex and year of diagnosis exhibit some time-varying patterns as well. Stage at diagnosis had the largest associations with survival. CONCLUSION These findings suggest that proportional hazards assumptions are often violated when examining patient characteristics on cancer survival post-diagnosis. We discuss several interesting results where the relative hazards are time-varying and suggest possible interpretations. Based on the time-varying associations of several important covariates on survival after cancer diagnosis using a pan-cancer approach, the likelihood of the proportional hazards assumption being met or corresponding interpretation should be considered in survival analyses, as flawed inference may have implications for cancer care and policy.

Abstract
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.

J Racial Ethn Health Disparities 2023:10.1007/s40615-023-01723-1. [PMID: 37540304 DOI: 10.1007/s40615-023-01723-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 06/08/2023] [Accepted: 07/06/2023] [Indexed: 08/05/2023]
Abstract
Lung cancer (LC) is the leading cause of cancer death among Asian-Americans. However, there are differences in LC incidence and mortality among Asian racial subgroups. The objective of this study was to describe LC burden and disparities among race/ethnic groups (White, Black, Asian, and Hispanic) across US census tracts (CT) in Philadelphia using the Pennsylvania Cancer Registry dataset (N=11,865). ArcGIS Pro was used to geocode patient addresses to the CT level for linkage to US Census data. Despite being diagnosed more frequently with advanced-stage lung cancer compared with other race and ethnic groups in Philadelphia, Asian patients were most likely to be alive at the time of data receipt. Among Asian subgroups, Korean patients were the oldest (median age 75, p=0.024). Although not statistically different, distant stage disease was the most prevalent among Asian Indian (77.8%) and Korean (73.7%) and the least prevalent among Chinese patients (49.5%). LC was the cause of death for 77.8% of Asian Indian, 63.2% of Korean, 52.9% of other Asian, 48.5% of Chinese, and 47.5% of Vietnamese patients. CTs where Asian individuals were concentrated had lower socioeconomic status and greater tobacco retailer density compared to the entire city. Compared to all of Philadelphia, heavily Asian CTs experienced a greater age-standardized LC incidence (1.48 vs. 1.42) but lower age-standardized LC mortality (1.13 vs. 1.22). Our study suggests that LC disparities exist among Asian subgroups, with Asian Indian and Korean Philadelphians most likely to present with advanced disease. Additional studies are needed to investigate LC among high-risk racial and ethnic groups, including Asian subgroups.

[PMID: 36882139 DOI: 10.1016/j.annonc.2023.01.010] [Citation(s) in RCA: 24] [Impact Index Per Article: 24.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Revised: 01/07/2023] [Accepted: 01/19/2023] [Indexed: 03/07/2023] Open
Abstract
BACKGROUND We aimed to predict cancer mortality figures for 2023 for the European Union (EU-27), its five most populous countries, and the UK. We focused on mortality from lung cancer. MATERIALS AND METHODS Using cancer death certifications and population data from the World Health Organization and EUROSTAT databases for 1970-2018 we predicted numbers of deaths and age-standardized rates (ASR) for 2023 for all cancers combined and the ten most common cancer sites. We investigated the changes in trends over the observed period. The number of avoided deaths over the period 1989-2023 were estimated for all cancers as well as lung cancer. RESULTS We predicted 1,261,990 cancer deaths for 2023 in the EU-27, corresponding to ASRs of 123.8/100,000 men (-6.5% vs 2018) and 79.3 for women (-3.7%). Over 1989-2023, about 5,862,600 million cancer deaths were avoided in the EU-27 compared with peak rates in 1988. Most cancers displayed favourable predicted rates, with the exceptions of pancreatic cancer, that was stable in EU men (8.2/100,000) and rose 3.4% in EU women (5.9/100,000), and female lung cancer which however tends to level off (13.6/100,000). Steady declines are predicted for colorectal, breast prostate, leukemia, stomach in both sexes and male bladder cancers. The focus on lung cancer showed falls in mortality for all age groups in men. Female lung cancer mortality declined in the young -35.8% (ASR 0.8/100,000) and middle aged (-7%, ASR: 31.2/100,000) but still increased 10% in the elderly (65+ years). CONCLUSION The advancements in tobacco control are reflected in favorable lung cancer trends, and should be pushed further. Greater efforts on the control of overweight and obesity, alcohol consumption, infection and related neoplasms, together with improvements in screening, early diagnosis and treatments may achieve a further 35% reduction on cancer mortality in the EU by 2035.

Clinical Characterization of the Expression of Insulin-Like Growth Factor Binding Protein 1 and Tumor Immunosuppression Caused by Ferroptosis of Neutrophils in Non-Small Cell Lung Cancer. Int J Gen Med 2023; 16:997-1015. [PMID: 36974063 PMCID: PMC10039630 DOI: 10.2147/ijgm.s401225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Accepted: 02/28/2023] [Indexed: 03/29/2023] Open
Abstract
Purpose The efficacy of immunotherapy for non-small cell lung cancer (NSCLC) is limited owing to cold tumors and drug resistance. Therefore, it is important to identify the molecular mechanisms underlying immune evasion in NSCLC. Spontaneous ferroptosis of neutrophils has been suggested as a key mechanism of immunosuppression in cancer. Insulin-like growth factor binding protein 1 (IGFBP1) plays an important role in immune infiltration in several cancers. However, the role of IGFBP1 in NSCLC is unknown. Therefore, in this study, we aimed to investigate the association of IGFBP1 mRNA expression with infiltration of myeloid-derived suppressor cells and prognosis in NSCLC. Patients and Methods Retrospective RNA-seq data from 990 patients in the Cancer Genome Atlas (TCGA) database were analyzed in relation to patient clinical characteristics. The Timer2 database was used to assess immune infiltration, and the FerrDb V2 database was used to obtain ferroptosis-related genes. Finally, the results were validated by the proteomic analysis of serum samples collected from six patients with NSCLC and six healthy individuals. Results IGFBP1 expression was enriched in lung adenocarcinoma samples and positively correlated with the pathological grade of NSCLC. IGFBP1 expression was an independent prognostic factor for the overall survival of patients with NSCLC. In addition, IGFBP1 expression correlated with myeloid-derived suppressor cell infiltration. Notably, Gene Ontology analysis of IGFBP1-related genes revealed that the major molecular functions of their protein products were related to NADP+ 1-oxidoreductase activity. Furthermore, expression levels of multiple ferroptosis suppressor genes positively correlated with IGFBP1 expression. Conclusion High IGFBP1 expression indicates a poor prognosis in patients with NSCLC, which may be related to tumor immunosuppression caused by neutrophil ferroptosis.
