To assess the safety and efficacy of intensity-modulated proton therapy (IMPT) for small cell lung cancer (SCLC)
To determine the optimal schedule for three-dimensional verification imaging and necessary re-planning of patients undergoing IMPT for a rapidly changing tumor (small cell lung cancer). * To determine the rate of cardiac toxicities from IMPT in patients with small cell lung cancer compared with historical controls receiving photon-based treatment. * To determine the rate of pneumonitis and esophagitis from IMPT and compare with historical controls receiving photon based treatment.
Inclusion Criteria: * Pathologically confirmed small cell lung cancer, limited or extensive stage. * Patients who are offered thoracic radiotherapy with intensity-modulated proton therapy (IMPT) techniques delivering 30-66 Gy in 15-33 fractions at 2 Gy per fraction, at the recommendation of the treating radiation oncologist. * Age 18 or greater Exclusion Criteria: * Prior radiation therapy which would provide significant dose overlap with the planned target volume(s) * Pregnancy
The goal of intensity-modulated proton therapy (IMPT) is to deliver radiation to the tumor while minimizing exposure to surrounding normal tissues.
