Continued smoking causes tumor progression and resistance to therapy in lung cancer. Carcinogens possess the ability to block apoptosis, and thus may induce development of cancers and resistance to therapy. Tobacco carcinogens have been studied widely; however, little is known about the agents that
OBJECTIVE
There is a current lack of consensus about the effectiveness of nicotine dependence treatment for cancer patients. This retrospective study examined the 6-month tobacco abstinence rate among lung cancer patients treated clinically for nicotine dependence.
METHODS
A date-of-treatment
BACKGROUND
Considerable effort has been expended on tobacco control strategies in the United States since the mid-1950s. However, we have little quantitative information on how changes in smoking behaviors have impacted lung cancer mortality. We quantified the cumulative impact of changes in smoking
The dominant role of tobacco smoking in the causation of lung cancer has been repeatedly demonstrated over the past 50 years. Current lung cancer rates reflect cigarette smoking habits of men and women in the past decades, but not necessarily current smoking patterns, since there is an interval of
Glutathione-S-transferases (GSTs) play a role in the detoxification of environmental chemicals and mutagens, such as those inhaled during tobacco smoking. There have been conflicting reports concerning GST polymorphisms as risk factors in the development of lung cancer. No studies focused on Arab
Exposure of nonsmokers to environmental tobacco smoke (ETS) is widespread in European countries, the most serious exposures occurring at home and in the workplace. Epidemiological studies available up to 1986 have been reviewed by several international and national authorities, which agreed in
BACKGROUND
To investigate the association between exposure to environmental tobacco smoke (EVT) and the incidence of lung cancer (LC) in nonsmoking adults.
METHODS
PubMed, Cochrane, Embase, Wanfang, CNKI, and VIP database were searched by the index words to identify the qualified case-control
BACKGROUND
The general population is nowadays well aware that tobacco smoking dramatically increases the risk of developing lung cancer. We hypothesized that a personal history of smoking and the level of nicotine dependence in current smokers may affect the perception of this risk among healthy
The objective of this study was to investigate a potential involvement of nicotinic cholinergic receptors in the mediation of cell type specific biological effects of nicotine and the two tobacco-related nitrosamines N-nitrosodiethylamine (DEN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone
OBJECTIVE
To study the relationship of per-capita tobacco consumption and lung cancer mortality in Henan province, and to provide evidence for policy development on tobacco control and reduction of lung cancer mortality.
METHODS
Data regarding lung cancer mortality and per-capita tobacco consumption
BACKGROUND
There is uncertainty regarding the association of occupational exposures with lung cancer. We have studied the association between 52 high-risk job titles and lung cancer incidence in a large prospective study, with more than 200,000 participants followed for more than 6 years and 809
BACKGROUND
Tobacco smoke is by far the greatest risk factor for non-small-cell lung cancer (NSCLC). Nicotine, an active alkaloid in tobacco, is unable to initiate tumorigenesis in humans and rodents, but can promote the growth and metastasis of various tumors, including NSCLC, initiated by tobacco
Nicotine-derived nitrosamine ketone (NNK) is considered a key tobacco smoke carcinogen inducing lung tumors. Physalis peruviana L (harankash) is considered one plant with marked health benefits. This study aimed to evaluate Physalis peruviana L effect on the toxic effect of NNK induced lung cancer
Every year, in Spain 18,000 new cases of lung cancer (LC) are diagnosed. Approximately, 80-90% LC in men and women are directly attributable to tobacco abuse. Cigarette smoke contains over 300 chemicals, 40 of which are known to be potent carcinogens. In the last decade, as in Spain, prevalence of
Patients with lung cancer continue to smoke owing to complex factors. Failure to quit smoking (defined as nicotine dependence) is significantly associated with genetic status. This study aimed to investigate the relationship between polymorphisms in nicotine dependence genes and
