156 Increasing re-planning rates for radical lung radiotherapy – the role of frequent cone beam IGRT and tumour size

Successful radical radiotherapy (RR) for lung cancer is dependent on accurately targeting areas of active disease with high doses of radiation result in geographic miss and under-treatment of areas of active disease. Regular imaging checks during treatment (IGRT) by skilled radiographers, help to ensure accuracy by altering setup to match with the radiotherapy plan. However significant intratarget changes, such as progression of local disease (lPD), or peri-target changes, such as collapse or re-expansion of the lung, may require a complete re-plan (re-P), which requires a duplication of all planning steps.
