Screening for occult lung cancer
Canadian Medical Association Journal
|April 15, 1983
Summary
Early lung cancer screening in Saskatchewan found only 10 cases, mostly advanced. A case of occult lung cancer highlights the potential for early detection and long-term survival with timely intervention.
Area of Science:
- Pulmonology
- Oncology
- Radiology
Background:
- Lung cancer screening aims for early detection.
- Pilot programs evaluate screening effectiveness.
Purpose of the Study:
- To assess the efficacy of a pilot lung cancer screening program.
- To evaluate early detection methods including chest roentgenography and sputum cytology.
Main Methods:
- A screening program was conducted in Saskatchewan in 1968.
- Target population: 23,000 men aged 40 and over.
- Methods: Chest roentgenography and sputum cytology.
Main Results:
- Only 10 lung cancer cases were detected.
- Nine cases presented with advanced disease.
- One case of occult lung cancer was identified, with a 31-month delay between cytologic detection and radiographic localization.
Conclusions:
- The pilot screening program had limited success with a broad target group.
- More focused target populations and frequent examinations could improve yield.
- Early detection of occult lung cancer offers potential for long-term survival.

Pulmonary Tuberculosis IV
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pneumothorax-II
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
