New Radiation Treatment for Lung Cancer

March 9, 2009 – Lung cancer is the number one cancer killer for men and women but these statistics may improve considerably, according to doctors at Temple University, who report a new treatment can double the chances of surviving the deadly disease – and without conventional radiation or surgery.
The doctors in Temple’s Radiation Oncology Department have treated only 50 people but say the technique, stereotactic body radiotherapy, or SBRT, not only improves a person’s odds of surviving early stage lung cancer, but may reduce the need for future surgeries.

“This is a big trend in radiation oncology for early stage lung cancer patients who either can’t undergo surgery or refuse it,” says Curtis Miyamoto, M.D., chair and professor of the Department of Radiation Oncology at the School of Medicine.

“With the success of this technique, we’re now questioning whether we’ll even be doing surgeries on these patients in the future.”

Treating lung cancer with conventional radiation is a burdensome process. Patients receive radiation therapy, which kills the cancerous cells and shrinks tumors, five days a week for six to seven weeks. The travel alone can be a hardship for patients not living in the city.

In contrast, SBRT requires only three to eight treatments, not 35. Once malignancy is confirmed through a PET CT scan or biopsy, treatments can begin.

Patients are placed in an immobilizing body frame to reduce movement so that doctors can focus radiation on the tumor while reducing exposure of healthy tissue
