- 1.1. One hundred ninety-nine exploratory thoracotomies for cytologically established carcinoma of the lung were performed at the Buffalo General Hospital and the Roswell Park Memorial Institute from January, 1947, to December, 1953.
- 2.2. The preoperative diagnosis was frequently made on x-ray evidence and clinical symptoms alone. Only 48 to 52 per cent had positive histologic or cytologic preoperative diagnoses.
- 3.3. The resectability rate for the combined series was 53 per cent.
- 4.4. The over-all operative mortality for exploratory thoracotomy without resection was 2.2 per cent. For the operation of pneumonectomy the combined operative mortality was 14 per cent, whereas no operative deaths occurred following lobectomies.
- 5.5. The three-year survival rate for those patients leaving the hospital alive between 1947 and 1950 following extirpation of their carcinoma was 22 per cent.
- 6.6. There was a remarkable similarity in the statistics obtained from the Buffalo General Hospital and the Roswell Park Memorial Institute. Both institutions serve the western part of New York State.
- 7.7. In the past few years, neither institution has noted any increase in the resectability rate. Delay in early diagnosis remains a grave obstacle to clinical progress.
- 8.8. Whether or not radical resection will increase eventual survival times cannot be calculated at present. In our hands it increases the morbidity of the operation of pneumonectomy.
