Stereotactic Radiosurgery Followed by Wedge Resection in Treating Patients With Early Stage Peripheral Non-small Cell Lung Cancer
This pilot clinical trial studies the side effects and how well stereotactic radiosurgery followed by wedge resection works in treating patients with early stage non-small cell lung cancer that is located in the outer, or peripheral, areas of the lung. Stereotactic radiosurgery, also known as stereotactic body radiation therapy, is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may kill more tumor cells and cause less damage to normal tissue. Wedge resection is a less invasive type of surgery for removal of the tumor and a small amount of normal tissue around it. Giving stereotactic radiosurgery followed by wedge resection may be a safe treatment option for patients who cannot receive standard treatment with lobectomy.

Who may be able to participate
The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.
- Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2
- Biopsy proven non-small cell lung cancer
- Maximum tumor dimension =\< 5 cm
- No clinical evidence of N1, N2 or N3 lymph nodes as assessed by CT and/or PET-CT
- No evidence of distant metastatic disease
- Tumor verified by a thoracic surgeon to be in a location that will permit a sublobar resection
- Tumor located peripherally within the lung (peripheral defined as not touching any surface within 2 cm of the proximal bronchial tree in all directions) and not touching the mediastinal pleura
- Pulmonary function tests (PFTs) with diffusing capacity of the lung for carbon monoxide (DLCO) within 90 days prior to registration
- Patient at high-risk of complications from lobectomy meeting a minimum of one major criteria or two minor criteria as described below:
- Major criteria
- Predicted postoperative forced expiratory volume in one second (FEV1) =\< 40%
- Predicted postoperative DLCO =\< 40%
- Age \>= 72
- Minor criteria
- Predicted postoperative FEV1 41-60%
- Predicted postoperative DLCO 41-60%
- Pulmonary hypertension (defined by a pulmonary artery systolic pressure greater than 40 mm Hg) as estimated by echocardiography or right heart catheterization
- Poor left ventricular function (defined as an ejection fraction 40% or less)
- Resting or exercising arterial partial pressure of oxygen (pO2) =\< 55 mmHg or oxygen saturation (SpO2) =\< 88%
- Partial pressure of carbon monoxide (pCO2) \> 45 mm Hg
- Modified Medical Research Council Dyspnea Scale \>= 3
- Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days following completion of therapy; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
- A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:
- Has not undergone a hysterectomy or bilateral oophorectomy; or
- Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)
- Ability to understand and the willingness to sign a written informed consent
- Pregnant women
- Patients with central tumors within the proximal tree or touching the mediastinal pleura
- Patients with evidence of distant metastatic disease
