Underuse of Chest Radiography Versus Computed Tomography for Lung Cancer Screening

Screening for lung cancer: time for large-scale screening by chest computed tomography.

Lung cancer is the leading cause of cancer death worldwide. Age and smoking are the primary risk factors for lung cancer. Treatment based on surgical removal in the early stages of the disease results in better survival. Screening programmes for early detection that used chest radiography and sputum cytology failed to attain reduction of lung cancer mortality. Screening by low-dose computed tom...

Computed tomography screening for lung cancer.

The development of CT technology reopened the lung cancer screening debate. Computed tomography screening for lung cancer certainly meets all the criteria required for an appropriate screening test. First and perhaps most importantly, the disease for which the screening is being performed should have a significant prevalence in the population being studied and be a significant health risk for t...

[Computed tomography in screening for lung cancer].

Technology and target group: Approximately 2 800 new cases of cancer in the lungs and respiratory tract are diagnosed annually in Sweden. By the time it is diagnosed, the cancer has usually spread in the body, and the 5-year survival rate following diagnosis is approximately 10 percent. If cancer could be detected at an early stage, the hypothesis is that it would substantially improve the prog...

Staging of Laryngeal and Hypopharyngeal Cancer: Computed Tomography versus Histopathology

Introduction: Computed tomography (CT) imaging is the choice of investigation for evaluation of extent of tumor under the mucosa, locally and regionally. This study was undertaken to assess the accuracy of preoperative CT imaging in the staging of carcinoma of the larynx and hypopharynx.   Materials and Methods: In this retrospective study, all cases who were clinically (c) staged T3–T4 and w...
