Objective To systematically review the evidence that smoking cessation
after diagnosis of a primary lung tumour affects prognosis.
Design Systematic review with meta-analysis.
Data sources CINAHL (from 1981), Embase (from 1980), Medline (from 1966),
Web of Science (from 1966), CENTRAL (from 1977) to December 2008, and
reference lists of included studies.
Study selection Randomised controlled trials or observational longitudinal
studies that measured the effect of quitting smoking after diagnosis of
lung cancer on prognostic outcomes, regardless of stage at presentation or
tumour histology, were included.
<snip>
Results
In 9/10 included studies, most patients studied were diagnosed as having
an early stage lung tumour. Continued smoking was associated with a
significantly increased risk of all cause mortality (hazard ratio 2.94,
95% confidence interval 1.15 to 7.54) and recurrence (1.86, 1.01 to 3.41)
in early stage non-small cell lung cancer and of all cause mortality
(1.86, 1.33 to 2.59), development of a second primary tumour (4.31, 1.09
to 16.98), and recurrence (1.26, 1.06 to 1.50) in limited stage small cell
lung cancer. No study contained data on the effect of quitting smoking on
cancer specific mortality or on development of a second primary tumour in
non-small cell lung cancer.
<snip>
Conclusions
This review provides preliminary evidence that smoking cessation after
diagnosis of early stage lung cancer improves prognostic outcomes. From
life table modelling, the estimated number of deaths prevented is larger
than would be expected from reduction of cardiorespiratory deaths after
smoking cessation, so most of the mortality gain is likely to be due to
reduced cancer progression. These findings indicate that offering smoking
cessation treatment to patients presenting with early stage lung cancer
may be beneficial.
Survival Odds Better For Cancer Patients Who Quit Smoking

A new study shows that people who are in the early stages of lung cancer
could double their chances of survival by quitting smoking.
The Associated Press reports that, until now, there was little evidence
available to show that smoking cessation in people with developing lung
cancer made any difference to survival.
<snip>
People who continued to smoke after discovering they had lung cancer had a
29 to 33 percent chance of living past five years. Those that were able to
quit has a 63 to 70 percent chance of surviving past five years.
Lung cancer is the most predominant type of cancer worldwide, and the
prognosis is usually not good. Patients who receive diagnosis late in the
cancer stage rarely make it to five years. The key to surviving is finding
the cancer early enough and to quit smoking.
The message is you should never give up on giving up (smoking). Amanda
Parsons, of the U.K. Centre for Tobacco Control Studies at the University
of Birmingham, told the Associated Press. Even at the stage where you have
been diagnosed with early stage lung cancer...if you give up smoking, your
body can still partially recover and your risk is reduced, she added.

UK Centre for Tobacco Control Studies
<http://www.ukctcs.org/>
The Centre is a strategic partnership of nine UK universities in England
and Scotland (Nottingham, Bath, Birmingham, Edinburgh, Stirling, Queen
Mary, UCL, York and Bristol) involving leading tobacco control researchers
from a range of disciplines.
Each institution will work together to deliver a programme of original
research, policy development, advocacy, teaching and training.
UKCTCS is part of a 20 million investment into public health research,
funded by the UK Clinical Research Collaboration (UKCRC) comprising the
Economic & Social Research Council, The British Heart Foundation, Cancer
Research UK, the National Institute for Health Research and the Medical
Research Council.
The other recently established Public Health Research Centres of
Excellence are:
North East Centre of Excellence for Translational Research in Public
Health, Newcastle University
Centre for the Development and Evaluation of Complex Interventions for
Public Health Improvement, Cardiff University (in collaboration with
Swansea University and Bristol University)

Research
<http://www.nottingham.ac.uk/ukctcs/Research.php>
The Centre conducts a comprehensive programme of research into smoking and
related issues. Work is organised into topics or themes and uses a range
of qualitative and quantitative research methods. The programme cover four
areas of investigation:
Exposure before birth (Smoking in pregnancy)
Smoking uptake and addiction (Determinants and prevention of smoking)
Stopping smoking (Cessation)
Efforts to reduce the damage caused by addiction to tobacco (Harm
reduction)
Studies undertaken by Centre may also be associated with a cross-cutting
theme and may cover more than topic. These themes (find out more) underpin
and inform the research programme, and are described as:
Methodological innovation and expertise
Inequalities in health
Policy analysis, evaluation and learning
Public involvement and partnership
