Sister chromatid exchanges in the peripheral blood of cigarette smokers and in lung cancer patients; and the effect of chemotherapy.
Peripheral blood sister chromatid exchange (SCE) rates in chronic cigarette smokers and in subjects with cancer do not differ from those in healthy nonsmokers. SCE patterns were normal in 69 chronic cigarette smokers, including 62 patients with untreated lung cancer. In three chronic smokers with lung cancer, high SCE levels were related to recent intravenous chemotherapy.
