Overview

Stereotactic Body Radiotherapy (SBRT) has emerged as a new treatment option for peripherally located lung tumours, offering very high rates of tumour eradication, with minimal side effects. Even though this treatment option is being adopted in more and more cancer centres, there is still no consensus about the optimal schedule for the radiation treatment. Generally speaking, most lung SBRT schedules involve delivering 3-4 days of radiation. At the Sunnybrook Odette Cancer Centre, the lung SBRT policy is to deliver 4 days of radiation over 11 days (each treatment given once very 3rd day). However, some centres deliver the same treatment over 4 days in a row (each treatment given once daily over 4 days). There is no evidence from the published literature to suggest that there is any difference in side effects between delivering the SBRT over 4 days versus 11 days. To confirm this, the investigators propose to conduct a comparative (randomized) study to compare these 2 approaches.
