Chemotherapy for lung cancer.

Oat cell carcinoma is the one variety of primary lung cancer which is sufficiently responsive to a variety of drugs and drug combinations that a very high rate of response and significant prolongation of survival can be consistently achieved. The question of whether anyone has been "cured" by drug treatment awaits more study and the passage of time. Progress in the treatment of the other varieties of bronchogenic carcinoma is less encouraging. There is only the hope that more fundamental knowledge about the nature of the disease will bring greater progress.
