简要总结
Primary Objective:
- Developing Common Toxicity Criteria (CTC) 3.0 grade > 3 treatment related pneumonitis (TRP) or
- Developing local-regional recurrence among patients treated with 3D conformal radiation therapy (CRT) (Arm 1) or intensity modulated radiation therapy (IMRT) (Arm 2).
Secondary Objectives:
- To assess and compare the time to develop CTC 3.0 grade > 3 radiation esophagitis in patients with non-small cell lung cancer (NSCLC) treated in arm 1 and arm 2.
- To investigate the association of inflammatory cytokines with the time to the development of radiation pneumonitis and outcomes to concurrent chemoradiation between arm 1 and arm 2.
- To investigate the association of relevant pharmacogenetics, biomarkers, and gene polymorphisms with the time to the development of radiation pneumonitis and treatment outcomes to concurrent chemoradiation between arm 1 and arm 2.
- To evaluate image guided adaptive radiation therapy (IGART) using weekly computed tomography (CT) on rail or cone beam CT in the assessment of tumor response and impact on treatment planning and delivery.
- To compare overall survival, progression-free survival, median survival time, in arm 1 and arm 2.
- To evaluate the role of functional image of fluorodeoxyglucose-positron emission tomography (FDG-PET) in assessing and predicting the time to the development of TRP and tumor response.
- To measure and compare symptom burden over time of the treatment using MD Anderson Symptom Inventory (MDASI)-Lung in the 2 arms.
- To determine the impact of comorbid conditions on survival.
详细描述
TRP (treatment related pneumonitis) is an inflammation (irritated or injured tissue) of the lungs that occurs as a result of chemotherapy or radiation therapy. TRP occurs because both chemotherapy and radiation affect normal lung tissue when tumors are being treated.
3D CRT is the current standard of care. It delivers radiation to several different angles of the body with center focus on the tumor(s). Because it is delivered at different angles, the same amount of radiation that contacts the tumor(s) also contacts normal lung tissue at each angle.
IMRT is a new type of radiation therapy. It also delivers radiation to several different angles of the body with center focus on the tumor(s). The difference is that the amount of treatment at each angle is adjusted according to the shape and size of the tumor(s), which in turn may decrease radiation exposure to normal lung tissue at each angle. Researchers want to find out if intensity modulated radiation therapy (IMRT) is able to decrease the amount of normal lung that is affected when treating lung cancer.
Before you can start treatment on this study, you will have "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. You will have a physical exam, including measurement of your vital signs (blood pressure, heart rate, temperature, and breathing rate). You will have blood drawn (about 1 tablespoon) and urine collected for routine tests. You will be asked about any other medical problems you may have that could cause the development of TRP. You will have tests that include a computed tomography (CT) scan, positron emission tomography (PET) scan, and lung function test. A PET scan is a scan that will show cells that take in higher levels of a type of sugar (glucose), such as cancer cells. Before the scan, a small dose of a slightly radioactive form of glucose will be injected through a vein. The cells that take in higher amounts of glucose will show up better on the scan. The scanning process is quite similar to a regular CT scan. No new biopsy is needed; only the original biopsy will be used for this study.
You will have 2 different single photon-emission computed tomography tests (SPECTs). You will have a lung single-photon emission computerized tomography (SPECT)test that will show the area of blood flow in the normal lung. You will have a heart single-photon emission computerized tomography (SPECT) test that will show the areas of blood flow in the heart. To perform these single-photon emission computerized tomography (SPECT) tests, you will have a slightly radioactive substance injected into your vein so that images can be seen of the blood flow in the lung and heart. This will help the study doctor try to avoid using radiation angles that would go through the normal blood flow area. You will also have a biopsy of your tumor tissue. To perform a tumor biopsy, an area of the body (where tumor is present) is numbed with anesthetic, and a small amount of tumor tissue is withdrawn through a large needle or with forceps (a tong-like instrument) during an endoscopic (viewing of body cavity with a special instrument) exam.

入选标准
- •Pathologically proven diagnosis of unresected loco-regionally advanced non-small cell lung cancer without evidence of hematogenous metastases, Stages IIB-IIIB without contralateral hilar nodal disease.
- •Patient is suitable for concurrent chemoradiation therapy per treating physician's assessment (kps >/= 70, weight loss < 10% in three months prior to diagnosis).
- •Patients with Stage IV NSCLC with solitary metastasis (brain, one side of adrenal gland, or one site of bone), who have clinical indication of concurrent chemoradiation to the primary disease in the lung are eligible.
- •Patients who received induction chemotherapy and then referred for concurrent chemoradiation are eligible.
- •Patients who had local regional recurrence after surgical resection and who are suitable for definitive concurrent chemoradiation are eligible.
- •Measurable disease by chest x-ray and/or contrast-enhanced CT, and/or PET scan
- •FEV 1> 1000 cc
- •Pre-chemoradiation FDG-PET within 10 weeks prior to randomization. This PET/CT is a standard procedure for staging. It is strongly encouraged to have this PET/CT performed at the same time for 4-D CT simulation using the 4-D PET/CT scanner at the department of radiation oncology.
- •Patient will undergo routine standard pretreatment evaluations as decided by treating physician, which usually include magnetic resonance imaging (MRI) or CT of the brain, contrast CT scan of the thorax and upper abdomen, pulmonary functional test, single-photon emission computerized tomography (SPECT), liver function tests (LFT), blood chemistry, renal functional test, complete blood count.
- •Age > 18, < 80 years
- •Patient must sign study specific informed consent prior to study entry.
排除标准
- •Evidence of small cell histology
- •Prior radiotherapy to the region of the study cancer that would result in overlap of radiation therapy fields
- •Pregnant women are ineligible as the treatment involves unforeseeable risks to the participant and to the embryo or fetus. Patients with childbearing potential must practice appropriate contraception.
- •Patient has enrolled in a clinical trial that specifically does not allow IMRT treatment
