Conditions

Non Small Cell Lung Cancer

Brief summary

The basic premise of this pilot study is to enroll 40 patients over 3 years who have Stage II, III, or IV non-small cell lung cancer and are planned for definitive treatment with concurrent chemoradiation where a contrast enhanced 4DCT is planned.

Inclusion criteria

* Patients have histologic diagnosis of non-small cell lung cancer * Patients have AJCC stage II, III or IV disease were the plan is to receive definitive concurrent chemoradiation to 60 Gy or higher * Age \> 18 years of age * Patients are able to provide informed consent * No additional lung radiation is planned until after the 2nd CT on this study (i.e. patient does not have a solitary pulmonary nodule or second primary that the plan is to undergo SBRT) * Patient must have adequate kidney function to receive IV contrast (following institutional policy supplied by radiology). The cutoff level for serum creatinine is 1.6 mg/dL * Negative urine pregnancy test before every CT scan

Exclusion criteria

* Allergy to IV iodine contrast * Severe claustrophobia * Further thoracic radiation therapy is planned.

Design outcomes

Primary

MeasureTime frame
evaluate the reproducibility of PBV DECT imaging and 4DCT derived lung ventilation for evaluating lung function3 years
correlate changes of PBV DECT and 4DCT lung function images seen at ~6 months with radiation dose and with patient reported outcome quality of life3 years

Secondary

MeasureTime frame
• To propose a novel biologic (i.e. functional) dose volume algorithm to reduce PBV and 4DCT lung function changes3 years
