AIMS: Modern radiotherapy uses techniques to reliably identify @entity5 and reduce target volume margins. However, this can potentially lead to an increased risk of geographic miss. One source of error is the accuracy of target volume delineation (TVD). Colleague peer review (CPR) of all curative-intent @entity2 plans has been mandatory in our institution since May 2013. At least two clinical oncologists review plans, checking treatment paradigm, TVD, prescription dose @entity5 and critical organ tolerances. We report the impact of CPR in our institution. MATERIALS AND METHODS: Radiotherapy treatment plans of all @entity1 receiving radical radiotherapy were presented at weekly CPR meetings after their target volumes were reviewed and signed off by the treating consultant. All cases and any resultant change to TVD (including organs at risk) or treatment intent were recorded in our prospective CPR database. The impact of CPR over a 13 month period from May 2013 to June 2014 is reported. RESULTS: One hundred and twenty-two @entity1 (63% @entity1149 , 17% @entity151 and 20% 'clinical diagnosis') were analysed. On average, 3.2 cases were discussed per meeting (range 1-8). CPR resulted in a change in treatment paradigm in 3% (one @entity1 proceeded to induction chemotherapy, two @entity1 had high-dose palliative radiotherapy). Twenty-one (17%) had a change in TVD and one (1%) @entity1 had a change in dose prescription. In total, 6% of @entity1 had plan adjustment after review of dose volume histogram. CONCLUSION: The introduction of CPR in our centre has resulted in a change in a component of the treatment plan for 27% of @entity1 receiving curative-intent lung radiotherapy. We recommend CPR as a mandatory quality assurance step in the planning process of all radical lung plans.
