The Memorial Sloan-Kettering Lung Study (MEM) was a randomized screening trial designed to test if lung cancer mortality rates could be reduced through the addition of regular cytomorphological screening of sputum to an annual chest x-ray screening regimen. The reported lung cancer mortality rates were similar between the two arms indicating the additional cytological screening did not result in a benefit. The follow-up of participants was of limited duration.
