Reduced Natural Killer Cells Percentage in Patients with Lung Cancer

Abstract

Increased as well as decreased percentages of NK cells of lung cancer patients in comparison to healthy control subjects have been reported. Percentage of NK cells in the peripheral blood were analyzed in 30 patients with lung cancer and 16 subjects of healthy control by flow cytometer technique using CD56+CD3-marker. Our result indicated that 13.3% of NK cells percentage of lung cancer patients was within normal range (with mean value 6.250 ±0.30204 % ) compared with 25% of healthy control subjects (with mean value 10.500±0.84764) as compared with normal NK cells percentage (5-15%).
