SBRT Shows Promise as Choice to Surgery for Early-Stage Lung Cancer

New research presented at the American Society for radiation Oncology (ASTRO) 2025 annual meeting suggests stereotactic body radiation therapy (SBRT) is an effective alternative to surgery for patients with early-stage, non-small cell lung cancer.
Study Findings: SBRT vs. Surgery
Researchers at the University of Texas MD Anderson Cancer Center compared outcomes for 80 patients treated with SBRT to 80 patients who underwent surgery. The study focused on patients with tumors less then three centimeters in diameter, without lymph node involvement or distant metastasis. The surgical group received video-assisted thoracoscopic lobectomy (VATS) and mediastinal lymph node dissection.
According to Dr. Kleber, SBRT offers advantages including a potentially easier recovery process and reduced financial burden for patients. Dr.Chang emphasized that a multidisciplinary care team is crucial for determining the best treatment option, as surgery remains the preferred approach for more complex, larger, or strategically located tumors.
Study Methodology
The clinical trial involved a direct comparison between two groups of patients. Both groups consisted of 80 individuals diagnosed with early-stage non-small cell lung cancer. Key inclusion criteria were tumors smaller than 3 centimeters, absence of lymph node involvement, and no evidence of distant metastasis. The surgical intervention involved video-assisted thoracoscopic lobectomy (VATS) coupled with mediastinal lymph node dissection. The SBRT group received stereotactic body radiation therapy, a highly focused form of radiation treatment.
Is SBRT Right for Everyone?
The study does not suggest that SBRT should be universally adopted as the first-line treatment for all patients with early-stage non-small cell lung cancer. Dr. Chang underscored the importance of a collaborative, multidisciplinary approach to treatment planning. Factors such as tumor complexity, size, and location play a critical role in determining the optimal course of action.Surgery remains the gold standard for certain patient profiles.
Understanding SBRT and VATS
Stereotactic Body Radiation Therapy (SBRT) is a highly precise form of radiation therapy that delivers high doses of radiation to a small, well-defined tumor while minimizing damage to surrounding healthy tissue. The National Cancer Institute provides detailed information on SBRT.
Video-Assisted thoracoscopic Lobectomy (VATS) is a minimally invasive surgical technique used to remove a lobe of the lung. It involves small incisions and the use of a camera and specialized instruments. The American Collage of Chest Physicians offers patient information on VATS lobectomy.
