Abstract

BACKGROUND: Studies examining the impact of lower socioeconomic status (SES) on the outcomes of patients with nonsmall cell lung cancer (NSCLC) are inconsistent. The objective of this study was to clearly elucidate the association between SES, education, and clinical outcomes among patients with NSCLC. METHODS: The study population was derived from a consecutive, retrospective cohort of patients with NSCLC who received treatment within the Duke Health System between 1995 and 2007. SES determinants were based on the individual's census tract and corresponding 2000 Census data. Determinants included the percentage of the population living below poverty, the median household income, and the percentages of residents with at least a high school diploma and at least a bachelor's degree. The SES and educational variables were divided into quartiles. Statistical comparisons were performed using the 25th and 75th percentiles. RESULTS: Individuals who resided in areas with a low median household income or in which a high percentage of residents were living below the poverty line had a shorter cancer‐specific 6‐year survival than individuals who resided in converse areas (P = .0167 and P = .0067, respectively). Those living in areas in which a higher percentage of residents achieved a high school diploma had improved disease outcomes compared with those living in areas in which a lower percentage attained a high school diploma (P = .0033). A survival advantage also was observed for inhabitants of areas in which a higher percentage of residents attained a bachelor's degree (P = .0455). CONCLUSIONS: Low SES was identified as an independent prognostic factor for poor survival in patients with both early and advanced stage NSCLC. Patients who lived in areas with high poverty levels, low median incomes, and low education levels had worse mortality. Cancer 2012. © 2012 American Cancer Society.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Disparities in race, sex, socioeconomic status, level of education, residence, and insurance status, among other factors, continue to be associated with outcomes such as mortality, incidence, stage at diagnosis, and timely receipt of recommended treatment for patients with NSCLC.

    “The results show that disparities in race,128–131 sex,132 socioeconomic status,132–135 level of education,136 residence,128,136 and insurance status,137–139 among other factors, continue to be associated with outcomes such as mortality,128,140 incidence,137,140 stage at diagnosis, and timely receipt of recommended treatment129,131 for patients with NSCLC.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
