An Outcome Analysis for Stereotactic Body Radiation Therapy (SBRT) Treatment of Non-Small Lung Cancer Patients Using 4D PET/CT With Real-Time Position Management (RPM™) System and a Concomitant Evaluation of the Impact and Performance Characteristics of the Immobilization System

This is an interventional other trial for Non Small Cell Lung Cancer Read More

The patient must be over the age of 18 years. Histologic confirmation of primary NSCLC of the lung tumor must be complete prior to SBRT treatment.

The following stages of NSCLC patients would be eligible for the study:

Stage I:

T1 N0 M0 T2 N0 M0 (Size ≤ 5 cm)

Stage II:

T3 N0 M0 (Chest wall invasion only, Size ≤ 5 cm)

Staging Tumor size and characteristics: they will be determined by PET-CT scan

Nodal disease:

Patients with chest CT scan demonstrating hilar or mediastinal nodes <1cm and/or PET negative would be considered N0 disease.

Patients who have hilar or mediastinal nodes > 1 cm and PET scan negative may be considered N0 disease.

If PET scan demonstrates suspicious uptake or abnormal uptake, these patients would be eligible, if a directed biopsy (by mediastinoscopy, Chamberlein procedure or other modalities such as trans-bronchial biopsy, CT guided biopsy) is negative.

Metastases:

Evaluated by PET-CT scanning and biopsy as indicated

The patient must have an ECOG/Zubrod performance status of 0, 1, or 2. In order to be considered medically-inoperable, the patient must meet at least one major criterion or meet a minimum of 2 minor criteria as described below.

MAJOR CRITERIA:

FEV1 < 50% or predicted postoperative FEV1 < 40% DLCO < 50% or predicted postoperative DLCO < 40% Exercise induced maximal exercise oxygen consumption (MVO2)<15 ml/kg/min Thoracic surgery consultation should be obtained from a Board Certified Thoracic surgeon who in collaboration with a radiation oncologist should determine if the patient is medically operable This criterion would be mandatory

MINOR CRITERIA:

Age > 80 Pulmonary hypertension (defined as a pulmonary artery systolic pressure greater than 40mm Hg) Oxygen requirement (using the Medicare criteria for home oxygen requirements [i.e., room air oxygen saturation of 88% or less]) Congestive heart failure (any three of the following must be documented: dyspnea, peripheral edema, chest x-ray with interstitial edema or cardiomegaly, rales, or congestion) Poor left ventricular function (defined as an ejection fraction of 40% or less) Severe cerebral (with CVA or recent TIA) or severe peripheral vascular disease Diabetes Mellitus with severe organ damage such as End-Stage Renal Disease (ESRD), Blindness, Vascular disease.

CBC, Diff and platelets, Comprehensive metabolic panel within 28 days of registration meeting the following criteria

leukocytes >3,000/mcL absolute neutrophil count >1,500/mcL hemoglobin >9 g/dL (hemoglobin may be supported by transfusion or erythropoietin or other approved hematopoietic growth factors) platelets >100,000/mcL total bilirubin <1.5x institutional upper limit of normal creatinine within normal institutional limits OR creatinine clearance >60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal.

Females of child-bearing age must be using a reliable form of birth control. The patient must provide a signed and dated written informed consent PRIOR to registration and prior to undergoing any study-related procedures.

The patient must provide written authorization to allow for the use and disclosure of their protected Health information.

Conditions for Patient Ineligibility The patient's weight exceeds the tolerances of the institution's imaging and treatment platform/couch.

The patient has received thoracic radiation therapy in the same region as the current SBRT planned treatment area. The patient has completed chemotherapy within 30 days of treatment. T2: Tumor size > 5 cm, T3 tumors (except T3 by virtue of chest wall invasion and ≤ 5cm), T4 tumors. Presence of N1, N2 or N3 disease per previously described criteria would also be excluded.

Pancoast tumors would be excluded. Current distant metastatic disease (M1) (preferably biopsy proven). The patient is a female with child-bearing potential who refuses to obtain a serum pregnancy test prior to the initiation of treatment.

The patient is pregnant or a female who is nursing an infant. The patient is planning on undergoing systemic therapy within 2 weeks after the last fraction of radiation The patient has an active systemic or pulmonary infection.
