Financial Hardship by Age at Diagnosis Including in Young Adulthood among African American Cancer Survivors.

Background: Financial hardship is most common among cancer survivors with the fewest financial resources at diagnosis; however, little is known about the financial outcomes of young adult (YA) survivors (ages 20-39 at diagnosis), despite their having fewer financial reserves than older adults.

Methods: We utilized data from 3,888 participants in the population-based Detroit Research on Cancer Survivors cohort. Participants self-reported several forms of material and behavioral financial hardship (MFH and BFH, respectively).

Smoking and genetic risk variation across populations of European, Asian, and African American ancestry--a meta-analysis of chromosome 15q25.

Recent meta-analyses of European ancestry subjects show strong evidence for association between smoking quantity and multiple genetic variants on chromosome 15q25. This meta-analysis extends the examination of association between distinct genes in the CHRNA5-CHRNA3-CHRNB4 region and smoking quantity to Asian and African American populations to confirm and refine specific reported associations. Association results for a dichotomized cigarettes smoked per day phenotype in 27 datasets (European ancestry (N = 14,786), Asian (N = 6,889), and African American (N = 10,912) for a total of 32,587 smokers) were meta-analyzed by population and results were compared across all three populations.

The relationship between chronic obstructive pulmonary disease and lung cancer in African American patients.

Rationale: Airflow obstruction and/or emphysema have been associated with lung cancer risk; however, this relationship and the joint occurrence of these conditions are not well studied in the African American population

Objective: To describe the prevalence of airflow obstruction and/or emphysema in African Americans with lung cancer and to evaluate their impact on the management and outcome of lung cancer.

Methods: Medical records of 114 African Americans who had participated in population-based case-control studies of lung cancer and who sought medical care at the Karmanos Cancer Center in Detroit, Michigan, were reviewed. The medical records of these patients were reviewed for demographics, type and stage of lung cancer, spirometry, treatment, and outcome.

Cytokine and cytokine receptor single-nucleotide polymorphisms predict risk for non-small cell lung cancer among women.

Studies on the relationships between inflammatory pathway genes and lung cancer risk have not included African-Americans and have only included a handful of genes. In a population-based case-control study on 198 African-American and 744 Caucasian women, we examined the association between 70 cytokine and cytokine receptor single-nucleotide polymorphisms (SNPs) and risk of non-small cell lung cancer (NSCLC). Unconditional logistic regression was used to estimate odds ratios and 95% confidence intervals in a dominant model adjusting for major risk factors for lung cancer.

Cytokine SNPs: Comparison of allele frequencies by race and implications for future studies.

The role of inflammation is being considered in chronic diseases. Previous studies have examined SNPs in a few key inflammatory genes and have included small numbers of African American participants. Variation in the frequencies of inflammatory pathway SNPs may help to explain racial disparities in disease risk.

COX-2/EGFR expression and survival among women with adenocarcinoma of the lung.

Previous studies suggest that cyclooxygenase-2 (COX-2) expression may predict survival among patients with non-small cell lung cancer. COX-2 may interact with epidermal growth factor receptor (EGFR), suggesting that combined COX-2/EGFR expression may provide predictive value. The extent to which their independent or combined expression is associated with prognosis in women with adenocarcinoma of the lung is unknown.

Regular adult aspirin use decreases the risk of non-small cell lung cancer among women.

Background: Prior studies indicate that use of aspirin or other nonsteroidal anti-inflammatory drugs (NSAID) is associated with a decreased risk of non-small cell lung cancer (NSCLC); however, results have been contradictory in part because of variation in study design. Few studies have examined the use of aspirin or other NSAIDs on risk of NSCLC in women.

Methods: Through a case-control study of African American and Caucasian women with and without NSCLC, we examined the relationship between use of aspirin, NSAIDs, and acetaminophen and risk of NSCLC.
