Study Overview
Brief Summary
Between 2010-2020, the LungCAst observational study followed 3700 patients newly diagnosed with lung cancer across 33 hospitals in Wales and England for 2 years to see if smoking status at time of diagnosis predicted survival rate. This research was sponsored and led by Hywel Dda University Health Board (HDUHB).
This new study examines the health records, (of only the HDUHB participants included in the original LungCAst study), over a longer period of time to see if the benefits of stopping smoking at point of diagnosis with lung cancer continues over a longer period of time (5 years+).
Detailed Description
A study into longer-term outcomes from the LUNGCAST study: comparing survival and healthcare utilisation according to smoking status in people with lung cancer, beyond 2 years. By obtaining Hospital Episode Statistics (HES) extract from the Welsh Patient Administration System (WPAS) and Welsh Clinical Portal (WCP) the investigators can retrospectively follow the cohort participants over time and analyse health care utilisation activity, using univariate and multivariate analysis on the effect of smoking status on survival. The Kaplan-Meier method, will be used to estimate the probability of survival over time.

Outcomes
Primary Outcomes
Comparison of longer-term (5 year+) outcomes (survival) of smokers, ex-smokers and never smokers diagnosed with lung cancer between 2010 and 2020
Time Frame: From date of diagnosis (of having lung cancer) for 5 years
Following participants with lung cancer over a 5 year period, by reviewing ongoing healthcare activity via HES extraction and applying the Kaplan-Meier method, to evaluate if smoking status at diagnosis predicts better survival rates over a longer period of time. Univariate and multivariate analysis on the effect of smoking status on survival will also be applied.
Secondary Outcomes
No secondary outcomes reported
