Abstract
Racial Disparities in Receipt of Lung Cancer Treatment in
Southwest Georgia
Background: Previous studies have revealed existing racial
disparities in the receipt of
treatment among different groups of lung cancer patients in large
urban settings. This study
aims at evaluating lung cancer treatment patterns in a primarily
rural region - Southwest
Georgia (SWGA).
Methods: This population-based retrospective cohort study
included 976 black and white
lung cancer patients who resided in SWGA and were diagnosed from
2001 to 2003. Cases
were identified through Georgia Cancer Registry (GCR).
Patient-/disease-related
characteristics, and treatment relevant data were obtained directly
from medical records. We
used logistic regression modeling to calculated crude and adjusted
odds ratios (ORs) and the
corresponding 95% confidence intervals (CIs) reflecting the
association between various
patient- and disease-related characteristics and receipt of
treatment for lung cancer (surgery,
radiation, chemotherapy). A separate analysis was conducted to
evaluate determinants of
receiving no treatment at al .
Results: No statistically significant associations were
observed between race (Black versus
White) and treatment receipt among SWGA lung cancer patients with
OR of 0.64 (95% CI:
0.39-1.06) for surgery, OR=0.84 (95% CI: 0.62-1.14) for radiation,
OR=0.64 (95% CI: 0.43-
0.96) for chemotherapy. Older patients had a statistically
significantly lower likelihood of
receiving treatment in al analyses. Married individuals were more
likely to receive any kind
of treatment compared with those not married (single, separated,
divorced, or widowed).
Patients with earlier stage of lung cancer were also more likely to
receive surgery but were
less likely to receive radiation and chemotherapy or have no
treatment at al .
Conclusion: Our findings confirmed previous reports
indicating that marital status and age
are important determinants of treatment receipt among lung cancer
patients. No racial
differences were observed in this largely rural region, which is
consistent with our earlier
observations in the SWGA population. Further investigations are
needed in both SWGA
and other rural areas of the country to extend the analysis beyond
treatment receipt, and to
evaluate predictors of treatment completion and survival among lung
cancer patients.
