How we made the decision
How we made the decision
We check our guidelines regularly to ensure they remain up to date. We based the decision on surveillance 4 years after the publication of lung cancer (2011) NICE guideline CG121.
For details of the process and update decisions that are available, see ensuring that published guidelines are current and accurate in Developing NICE guidelines: the manual.
New evidence
We found 298 new studies in a search for randomised controlled trials and systematic reviews published between 28 May 2012 and 8 June 2015.
Evidence identified in an Evidence Update from 2 years after publication of the guideline was also considered. This included 22 studies identified by a literature search.
From all sources, 320 studies were considered to be relevant to the guideline.
We also checked for relevant ongoing research, which will be evaluated again at the next surveillance review of the guideline.
See appendix A: decision matrix for summaries and references for all new evidence considered.
Views of topic experts
We considered the views of topic experts, including those who helped to develop the guideline.
Views of stakeholders
Stakeholders are consulted only if we decide not to update the guideline following checks at 4 and 8 years after publication. Because this was a 4-year surveillance review, and the decision was to update, we did not consult on the decision.
See ensuring that published guidelines are current and accurate in Developing NICE guidelines: the manual for more details on our consultation processes.
