Stereotactic Body Radiation Therapy After Surgery in Treating Patients With Stage III-IV Non-small Cell Lung Cancer

PRIMARY OBJECTIVES:

I. To assess the feasibility/toxicity of combining transcervical extended mediastinal lymphadenectomy (TEMLA) with or without video-assisted thoracoscopic surgery (VATS) and stereotactic body radiation therapy (SBRT).

SECONDARY OBJECTIVES:

I. To assess time to initiation of chemotherapy following TEMLA with or without video-assisted thoracoscopic surgery (VATS)and SBRT.

II. To assess feasibility/toxicity of combining TEMLA with or without VATS and SBRT with various chemotherapy regimens (to be determined by medical oncologist based on patient and tumor characteristics).

III. To estimate survival following TEMLA with or without VATS and SBRT. IV. To define any differences in quality of life/toxicity following TEMLA with or without VATS and SBRT based on tumor location (peripheral/central).

V. To assess response for primary tumor control and overall survival in TEMLA only patients.

VI. To assess progression free survival for TEMLA with or without (VATS) patients.

OUTLINE:

Patients undergo TEMLA to remove the mediastinal lymph nodes followed by a single fraction of SBRT to the primary tumor (unless VATS procedure done) and mediastinal lymph node beds (if positive on TEMLA), with or without VATS.

After completion of study treatment, patients are followed up at 6,9, and 12 months, every 6 months for 2 years and annually for 2 years.

Inclusion criteria

• Have an Eastern Cooperative Oncology Group (ECOG) performance status of =< 2
• Have histologically proven diagnosis of non-small cell lung cancer (NSCLC) (stage III and stage IV [to include limited volume metastases such as brain, bone, adrenal])

• Patient or legal representative must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving and study related procedure
• Patients with chemotherapy prior to TEMLA are eligible

Exclusion criteria

• Contraindication to SBRT or TEMLA; this includes the inability to cooperate with any aspect of SBRT such as the inability to lie still and breathe reproducibly
• If patient has an open thoracotomy for lung cancer they will not be able to receive SBRT and will be replaced
• Pregnant or nursing female patients
• Unwilling or unable to follow protocol requirements
• Any condition which the investigator's opinion deems the patient ineligible
• Received an investigational agent within 30 days prior to enrollment
