Heterogeneously Hypofractionated Radiotherapy for Locally Advanced NSCLC

A heterogeneous hypofractionated schedule for the treatment of high-risk locally advanced NSCLC patients in which the central idea is to decrease dose to normal tissue by ascribing a heterogeneous dose to the PTV. The dose to the periphery of the PTV as well as to the majority of lymph node targets is decreased compared to a standard treatment. The gross volume of the primary tumour and bulky lymph nodes receive mean doses of up to 66 Gy in 24 fractions, and thus receive a hypofractionated higher biological effective dose than standard 66 Gy in 33 fractions.
