Patient Resources: Understanding Oligometastases and SBRT

A recent study presented at the 56th Annual Meeting of the American Society for Radiation Oncology (ASTRO) reported that stereotactic body radiation therapy (SBRT) benefits patients with advanced oligometastatic lung cancer.

Oligometastasis, a form of metastatic cancer, is the intermediate state of metastasis. Metastatic cancer occurs when cancer cells break away from a primary tumor site and spread to additional parts of the body. Despite spreading to another location within the body, the cancer is considered an extension of the original tumor.

The study was a large, international, individual patient data meta-analysis which revealed that SBRT or surgery can achieve long-term survival in some patients with oligometastatic stage IV non-small cell lung cancer (NSCLC). The results of the study were used to develop a risk-stratification model that can be beneficial in identifying which patients are the best candidates to receive SBRT or surgery.

If you or a loved one is diagnosed with metastatic lung cancer, contact St. Louis CyberKnife to learn more about SBRT with CyberKnife® as a potential treatment option.
