Nearly 10 percent of smokers hospitalized for pneumonia are diagnosed with lung cancer within one year, a new study finds

Lung cancer is the leading cause of deaths from the disease in the U.S., with a five-year survival rate of just 17 percent.  This is generally because by the time the disease is diagnosed it has already spread.

Now a new study from Israel is proposing that screening heavy smokers admitted to the hospital with pneumonia could lead to early diagnosis of lung cancer, thereby reducing the death rate.

The researchers examined 381 cases of heavy smokers hospitalized with community-acquired pneumonia, which is a form of pneumonia contracted outside a hospital setting. They then crosschecked with the database at Israel's National Cancer Registry for new diagnoses of cancer.

The researchers found that out of 381 admissions of heavy smokers with pneumonia, 31 -- nine percent, a figure that surprised the researchers -- were diagnosed with lung cancer within a year of being hospitalized. This compared to the 0.5-1 percent of smokers without pneumonia that are diagnosed with lung cancer each year, they say.

These excess patients with lung cancer may have already had the disease, and had obstructed the airway, resulting in an infection that was masquerading as pneumonia, the researchers theorize in their study.

This finding suggests that heavy smokers who are admitted to the hospital with pneumonia should undergo special CT scanning to find out whether they actually have lung cancer, the researchers say of their study, which appears in the American Journal of Medicine.
