Lung cancer is a common malignancy worldwide, and risk factors include bronchitis, asthma, tuberculosis, smoking, and air pollution. These are also risk factors for spontaneous pneumothorax, a benign disease. We hypothesized that patients who experience a spontaneous pneumothorax have a greater risk to develop lung cancer, and designed a study to determine if this is so. We used the population-based Taiwan Health Insurance Research Database to perform a retrospective cohort study. The database includes more than 99% of the population of Taiwan. We established a 27,405-person pneumothorax cohort and a 109,620 person compar...

Have you ever spent the day in a city with such bad air pollution that when you blew your nose the mucus had a black tinge? Have you ever coughed as you breathed in diesel fumes from a passing bus and thought to yourself, “Well, that’s a year gone from my life”? Could it actually be true — that air pollution leads to an early death? The answer, in fact, is an unqualified yes. Air pollution causes heart disease, lung disease, and early death It has been known for some time that air pollution causes lung cancer, chronic obstructive pulmonary disease, emphysema, asthma, heart disease, and stroke. One r...

Conclusion: Quantitative SPECT/CT is useful in pre-surgical evaluation or radiation treatment planning of patients with pulmonary nodule or lung mass. Larger sample size of patients with underlying emphysema is needed to further evaluate the utility of this technique. We recommend Quantitative perfusion SPECT/CT for lobar assessment than traditional regional quantitative perfusion prior to surgery.

Emphysema is one of three main lung pathologies in Chronic Obstructive Pulmonary Disease, along with chronic bronchitis and small airway obstruction. The diagnosis is based on detection of low attenuation areas in lung tissue on chest Computed Tomography, either visual by a radiologist, or automatic by the applied Computed Tomography software. Results of the studies on the association between emphysema and lung cancer incidence are mixed. Many studies have demonstrated, that chronic lung diseases, like Chronic Obstructive Pulmonary Disease, are associated with lung cancer morbidity.

Lung cancer is the leading cause of cancer mortality in both men and women in the United States, with an estimated 154,050 deaths expected to occur in 2018 [1]. Cigarette smoking has been linked to the development of lung cancer and chronic obstructive pulmonary disease (COPD) [2] and COPD has been found to be independently associated with an increased risk of developing lung cancer. A pooled analysis of 17 epidemiologic studies reported a 2.4-fold increase in risk of lung cancer associated with emphysema (ORmeta  = 2.44, 95% CI: 1.64, 3.62), and a 1.5-fold association with chronic bronchitis (ORmeta =...

This study actually does support the harm reduction potential of e-cigarettes,” says Andy Tan, an assistant professor of population sciences at Dana-Farber Cancer Institute who has studied e-cigarettes. “Yes, vaping is associated with about 29% to 31% higher odds of subsequent lung disease within two to three years than not vaping—but compare this with the 156% higher odds of using combustible tobacco than not smoking.” For the purposes of the study, Glantz and his co-author combined four conditions—chronic obstructive pulmonary disease (COPD), chronic bronchitis, emphysema and asthma—in...

CONCLUSION: The increase of miR-7 methylation levels experienced by COPD patients occurs mainly at the expense of the emphysema phenotype, which might contribute to explain the higher incidence of lung cancer in these patients. PMID: 31780284 [PubMed - as supplied by publisher]
