The in vitro sensitivity of 193 lung tumour specimens to anticancer agents was investigated using the short-term culture method. It is shown that there are many anticancer drugs with correlative effectiveness. It often concerns preparations with different mechanism of action. Using the in vitro sensitivity test data of correlative effectiveness it is possible not only to investigate the activity of new synthesized compounds and well known preparations but also to draw poly-chemotherapy schemes with these agents in relatively short time.
