Slide 6

Conclusion Annual spiral CT screening can detect lung cancer that is curable Comparable screening efficacy as mammographic screening for breast cancer (prevalence 1.6%; incidence 0.6%) Cost effective - low energy, fast scanning about $200 Treatment of early stage disease less expensive than advanced disease

Slide 7

Controversy

Slide 8

CT scans have radiation risks and sometimes detect cancers that would not have progressed, leading to risky procedures like biopsies and lung surgery when not needed. lung surgery lung surgery

Slide 9

The National Cancer Institute started in 2002 the $200 million National Lung Screening Trial comparing death rates among 55,000 people randomly assigned to have CT scans or chest X- rays. Results are not expected until 2010.

Adjuvant Radiation Therapy External beam radiation therapy - Potential risk of increased injury to surrounding pulmonary parenchyma What is efficacy of intraoperative brachytherapy when external beam radiation may otherwise be applied?

Slide 31

Intraoperative Brachytherapy Not a new concept for lung cancer Mostly used for Stage IIIA disease - close or positive margins Improved local control What is its role in high risk patients with totally resectable disease where lobar resection is not feasible and adjuvant radiotherapy is recommended?

Dr. Henschke has asserted that allowing hundreds of thousands of people to die in the meantime is unethical. Therefore, off study CT screening should be approved by insurance for high risk patients!
