Cure of lung cancer from incomplete surgical resection

Three patients with lung cancer have been cured by incomplete removal of the cancer, which has for 20 years been the policy of this unit when complete removal is not possible. In each patient residual cancer remained on the wall of the left atrial chamber of the heart at the end of an operation for pneumonectomy.Incomplete removal of cancer may, as a rare event, cure the patient. When residual cancer remained on any mediastinal structure other than the atrium cure has not been seen, though progress of the cancer seems to be retarted in some patients.
