Stereotactic Body Radiation Therapy for Un-biopsied Early- Stage Non Small Cell Lung Cancer

December 15, 2023 updated by: Matthew Harkenrider, Loyola University

Phase II Study of Stereotactic Body Radiation Therapy for Un-biopsied Early- Stage Non Small Cell Lung Cancer

Lung cancer is the leading cause of cancer death in both men and women in the United States. In 2014, an estimated 224,210 men and women were diagnosed with carcinoma of the lung and bronchus, resulting in 159,260 deaths. Per the current National Comprehensive Cancer Network (NCCN) guidelines, the standard of care for early-stage non-small cell lung cancer (NSCLC) is lobectomy with lymph node dissection. Historically, medically inoperable early-stage NSCLC patients have been offered definitive external beam radiotherapy (EBRT) as primary management but, overall, studies have consistently shown poor patient outcomes. Stereotactic body radiation therapy (SBRT) is a technique which delivers very high doses of radiation per fraction over one to five fractions to precisely defined volumes with steep dose gradients. SBRT is commonly utilized for the treatment of biopsy-proven early stage NSCLC in the medically inoperable patient.

Detailed Description

This purpose of this study is to learn about the good and bad effects of treating early stage lung cancer without having a biopsy of the tumor. Participants in this research will receive a type of radiation treatment called Stereotactic Body Radiation Therapy (SBRT). This type of radiation is targeted directly at the tumor so that damage to surrounding normal tissue can be avoided. SBRT is often used in treating patients with biopsy proven early stage lung cancer who cannot have surgery for medical reasons. In this study, SBRT is considered experimental because the tumor has not been biopsied. SBRT for early-stage NSCLC has consistently proven to provide excellent local control and improved overall survival in the medically inoperable patient. The constancy of this finding over a variety of dose schedules confirms the robustness of SBRT. This study will utilize 54 Gy in 3 fractions delivered twice weekly for peripheral lesions. In order to respect the increased risk of adverse events our dose for centrally located lesions will be reduced to 50 Gy in 5 fractions delivered twice weekly and for chest wall or rib adjacent lesions will be 60 Gy in 5 fractions. These doses are consistent with Radiation Therapy Oncology Group (RTOG) 0236 for peripheral lesions and RTOG 0813 for central lesions and are both ≥100 Gy Biological Effective Dose (BED) as previously discussed . The investigators of this study routinely prescribe 60 Gy in 5 fractions for rib adjacent lesions.

The primary objective is to assess acute and chronic toxicities associated with SBRT of unbiopsied early-stage NSCLC.

Secondary objectives include:

To evaluate the disease specific outcomes of local control, lobar failure-free survival, regional/nodal failure-free survival, distant metastasis-free survival, disease-free survival, cause-specific survival, and overall survival associated with SBRT of unbiopsied early-stage NSCLC patients.

To evaluate Pulmonary Function Test (PFT) changes over time following SBRT of unbiopsied early-stage NSCLC patients.

To evaluate the patient's overall quality of life before and after treatment with SBRT of unbiopsied early-stage NSCLC patients.

Medically-inoperable patient due to one of the criteria below

  • Poor pulmonary function for resection including baseline Forced Expiratory Volume in 1 second (FEV1), FEV1 <50%, post-operative predicted FEV1<30% predicted, diffusion capacity <50%, baseline hypoxemia and/or hypercapnia. Patients with severe obstructive or restrictive lung disease will be eligible for inclusion.
  • Pulmonary hypertension

Absence of pathological diagnosis due to one of the criteria below

  • High risk of complications from transbronchial or transthoracic biopsy
  • Biopsy was performed or attempted but with complications requiring abortion of procedure
  • Biopsy was performed and non-diagnostic for malignancy but without other diagnosis to explain the clinical and radiographic findings
  • Patient declines biopsy Stage T1-3, N0, M0 (AJCC Staging, 7th Ed.) based upon the following diagnostic workup

  • Diagnostic imaging (CT and/or PET/CT) Serial computed tomography and/or positron emission tomography imaging clinically consistent with lung malignancy.
  • CT scan with contrast (unless medically contraindicated) within 6 weeks of registration. The tumor dimensions will be measured on CT with greatest dimension ≤5cm.
  • Whole body Positron Emission Tomography / Computerized Tomography (PET/CT) within 12 weeks of registration. Standard uptake value (SUV) must be available but no minimum SUV is required for inclusion.
