About
The purpose of this institutional protocol is to offer SBRT to selected patients in a controlled environment to refine treatment techniques (including dose/fractionation schedules) and standardize follow-up. SBRT has been in clinical use for over a decade in some institutions and the available data suggest that it can be used safely and with good results. This study will see how effective Stereotactic Body Radiation Therapy is for treating tumours in the lung and how often people have side effects. Radiation therapy is usually given once a day, often for a few weeks. In this study, study participants will receive high doses of radiation treatment to tumours in the lung for 3 to 10 treatment sessions over a total of about 1 to 2 weeks.
Several reports indicate that this therapy might shrink tumours and control the cancer for extended periods of time. Although specialists started to treat patients with SBRT over 10 years ago, it is still used in relatively few cancer centres.
Full description
SBRT is an adaptation of the principles and experience gained from stereotactic brain RT. SBRT was developed in the early 90s at the Karolinska Institute in Stockholm, Sweden, and is used as an accepted alternative of treatment for patients with early stage lung cancer in many centers in Japan and a number of centers in Germany,USA and elsewhere. It is also now being used for patients who have lung metastases and extra-thoracic disease (primary or metastatic). Many reports indicate excellent local control (80-90% or higher) and minimal toxicity in well selected patients treated with thoracic SBRT.
