Clinical and epidemiological characteristics of lung cancer cases in Qatar

This study documents for the first time the clinical and epidemiological characteristics of lung cancer cases in Qatar from 1998 to 2005. The age-standardized incidence rate was higher than that in many other Gulf countries: 8.95 per 100 000 [15.2 per 100 000 for males; 3.95 per 100 000 for females]. Mean age at diagnosis was 57.5 years. Most patients were current smokers or ex-smokers at the time of diagnosis [82.5%]. Unlike other Gulf countries, adenocarcinoma was the predominant type in both Qatari nationals and expatriates [43.9% of lung cancer types]. Many cases were in an advanced stage at diagnosis [64.2% at stage IV]. Incomplete information was available on mortality rate due to the migration of expatriates

Endobronchial Tuberculosis Simulating Lung Cancer and Healing without Bronchial Stenosis.

Endobroncheal tuberculosis is defined as tuberculous infection of the tracheobronchial tree with microbial and histopathological evidence. The disease is usually mistaken for other lung diseases including lung cancer. Bronchial stenosis is a common complication of this type of tuberculosis despite the use of effective anti-tuberculous chemotherapy. We are presenting a case of endobronchial tuberculosis that simulated lung cancer and healed without residual bronchial stenosis.
