A 75-year-old man presents to his physician
with a 4-week history of exertional shortness of
breath. He worked as a pipe fi tter for 45 years,
retiring 5 years ago. He denies chest pain, palpitations,
swelling in his legs, cough, hemoptysis,
and weight loss. He smokes 1 pack per day
and has done so for the past 45 years. His temperature
is 36.7°C (98°F), pulse is 85/min,
blood pressure is 120/80 mm Hg, respiratory
rate is 14/min, and oxygen saturation is 99% on
room air. Physical examination is unremarkable.
Pulmonary function testing shows a mild
restrictive pattern with a normal diffusing capacity.
X-ray of the chest shows linear opacities
at the lung bases and pleural plaques. Which
of the following is the most appropriate intervention?
(A) High-resolution CT of the chest
(B) Pulmonary function testing
(C) Repeat sputum cytology every 6 months

The correct answer is E. Squamous cell carcinoma and adenocarcinoma are the most common cancers associated with asbestos exposure, which is associated with a sixfold increase in lung cancer. This risk increases to 59-fold with a concurrent smoking history. Therefore, the most appropriate intervention in this patient is smoking cessation. The average time between the exposure to asbestos and the development of lung cancer is 15 years. The patient has signs and symptoms of asbestosis (shortness of breath, restrictive pattern on pulmonary function testing, and a chest radiograph showing linear opacities and pleural plaques). Specific therapy, such as steroids or immunosuppressive or antifibrotic agents, may also be warranted.

High resolution CT is most commonly done in two conditions:
1. Bronchiectasis
2. ILD

In ILD the DLCO is decreased.
