entrometric dots (cd)of periferal blood samples from 17 cases of lung cancer
10cases of benign pul-monary lesions and 11 normal persons were studied by Cd-banding technique. The results showed that thefrequencies of Cd loss were significantly bigher in patients with lung cancer than those of benign pulmonarylesions and controls(P<0. 001)we suggested that cell aneuploid occurredce in lung cancer might relate to thechange in Cd
The relationship between the cell aneunploid exsitin cancer and abnormal Cd change was alsodiscussed.
