MIAMI, Oct. 6 (UPI) — Race itself does not predict overall survival among African-American patients with lung cancer, U.S. researchers say.
Dr. Rajesh Sehgal of the Marshall University Joan C. Edwards School of Medicine in Huntington, W.Va., and colleagues found median overall lung cancer survival was 10.3 months for Caucasian patients, 9.1 months for African-American patients and 11.8 months for patients of “other” — non-African American and non-Caucasian — races.
Fewer African-American patients than Caucasian patients underwent surgery and a greater percentage presented with metastatic lung cancer — factors that may have contributed to their less favorable median overall survival.
The researchers conclude race alone did not affect overall survival, but race was an independent risk factor for patients of “other” races — including Asian and Hispanic patients — who had a better disease prognosis versus Caucasian patients.
“If possible, we would like to look into the tumor biology of ‘other’ races to see when differences exist in their tumors as compared to Caucasian and African-American patients and whether these differences might account for their better prognosis,” Sehgal said in a statement.
The study findings of the study — based 130,517 Cancer Information Resource File patients diagnosed with lung cancer from 2003 to 2008 — were presented at the American Association for Cancer Research Conference on The Science of Cancer Health Disparities in Miami.
