Radiation treatment with focused beams may improve lung cancer survival

April 14, 2010
A radiation therapy that relies on targeted tumor control may cause less treatment-related illness and may improve survival for patients with inoperable lung cancer, according to a new study.

The study by scientists at the University of Texas Southwestern Medical Center in Dallas was recently published in a JAMA issue on cancer.

The research team pointed out that patients with inoperable early stage lung cancer are often given conventional radiation of 20 to 30 treatments or observed without specific therapy. By contrast, the targeted radiation – called stereotactic body radiation therapy (SBRT), a noninvasive cancer treatment – uses small and focused radiation beams to deliver potent doses in one to five treatments directed at tumors.

"The main finding in this prospective study was the high rate of primary tumor control [97.6 percent at three years]…an essential requirement for the cure of lung cancer," the researchers reported. "[SBRT] provided more than double the rate of primary tumor control than previous reports describing conventional radiotherapy."

At the North Shore-LIJ Health System's Radiation Medicine Department, patients are diagnosed with primary and secondary cancers by using innovative radiation procedures that target malignancy and reduce the amount of radiation to non-cancerous tissue.ADNFCR-2730-ID-19721048-ADNFCR
