About

This phase I trial studies the side effects and best dose of radiation therapy when given together with cisplatin and etoposide in treating patients with non-small cell lung cancer that cannot be removed by surgery. Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Drugs, such as cisplatin, may make tumor cells more sensitive to radiation therapy. Giving radiation therapy together with cisplatin and etoposide may kill more tumor cells.

Full description

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of escalating doses of radiotherapy (RT) administered concomitantly with a fixed dose of cisplatin and etoposide within the same overall treatment time.

OUTLINE: This is a dose-escalation study of radiation therapy.

Patients undergo 3-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiotherapy (IMRT) 5 days a week for 8 weeks. Patients also receive cisplatin intravenously (IV) over 60 minutes on days 1, 8, 28, and 36 and etoposide IV over 60 minutes on days 1-5 and 28-32.

After completion of study treatment, patients are followed up at 8 weeks and 6 months.

Enrollment: 6 patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients with confirmed unresectable Stage IIB or Stage III non-small cell lung cancer of any histologic-subtype appropriate for definitive concurrent chemotherapy and radiation as determined by multi-disciplinary assessment; all detectable tumor should be encompassable by radiation therapy fields, including both the primary tumor and the involved regional lymph nodes
• Granulocytes >= 1500/ul
• Platelets >= 100,000/ul
• Bilirubin < 1.5 mg/dl
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) < 2 upper limit of normal (ULN)
• Creatinine clearance must be > 60ml/min
• Eastern Cooperative Oncology Group (ECOG) 0 to 1
• Weight loss =< 5% in the previous six months unless weight loss is intentional (per judgment of study medical doctor [MD])
• Forced expiratory volume in one second (FEV1) must be >= 1.0 L
• Patients must sign a study-specific informed consent form prior to study entry
• Patients must have measurable disease on the 3D planning computed tomography (CT)
• Patient must have a completed 3D plan and the attending physician must have reviewed and approved the dose volume histograms as follows: total lung volume percentage receiving at least 20 Gy (V20) =< 35%, and mean lung dose =< 20 Gy

Exclusion criteria

• Mixed histology or undifferentiated small cell carcinoma, any stage
• Concurrent malignancy except non-melanomatous skin cancer or prior cancer if disease-free for one year or more
• Patients with malignant pleural effusions or significant pericardial effusions
• Pregnant or lactating females
• Severe neuropathy greater than or equal to grade 2
• Severe sensorineural hearing loss greater or equal to grade 2
• No clinically significant history of cardiac disease, (i.e. uncontrolled hypertension, unstable angina, congestive heart failure, myocardial infarction within the past year, or cardiac ventricular arrhythmias requiring medication)
• Any significant or severe medical conditions or psychiatric or social conditions that would preclude adherence to the protocol or compliance with study treatments
