Brief Summary
The goal of this clinical research study is to study the safety of giving larger daily doses of proton radiation therapy than the standard dose levels given to treat lung cancer. Researchers want to find the highest daily dose of proton radiation that can be given without having to stop therapy due to side effects.

Outcome Measures
Primary Outcomes (1)
Maximum Tolerated Dose (MTD) of Hypofractionated Proton Therapy
Dose-limiting toxicity (DLT) defined as any CTCAE v4.0 grade 4 complication of esophagus or skin, or any grade 3 or higher complications of other organ systems (i.e. lung, liver, kidney, or GI tract), unless these complications are deemed to be related to those of esophagus. DLT assessed within 1 month of completion of radiation therapy. MTD defined as highest dose for which probability of toxicity is closest to 25%.
1 month after completion of radiation therapy
Study Arms (1)
Proton Therapy
EXPERIMENTALThe radiation prescription dose ranges from 45 Gy in 3 Gy fractions to 60 Gy in 4 Gy fractions. Patients will be assigned to receive 1 of 3 doses of radiation therapy, based on when they joined the study. The first group of at least 3 participants will receive the lowest total radiation dose. If the first dose is tolerated well by the first group of participants in this study, then the next group of participants will receive the second, higher dose of radiation. If this dose is tolerated, then a third group will be treated at the highest dose.
Interventions
The regimen of 45 Gy in 15 fractions will be delivered as a baseline, and then the fraction size will be escalated in two different intervals of 0.5 Gy each, with the ultimate dose being 60 Gy in 4 Gy fractions.
Eligibility Criteria
You may qualify if:
- Histologically or cytologically documented NSCLC, SCLC, thymic tumors, or carcinoid tumors
- Patients not receiving concurrent chemotherapy
- Patients that are eligible for concurrent treatment with biologic agents (epidermal growth factor receptor \[EGFR\] or vascular endothelial growth factor \[VEGF\] inhibitors) will be eligible for the study.
You may not qualify if:
- Prior radiotherapy to the chest
- Life expectancy \<6 months
- Pregnancy
