Modern 3-D radiation therapy has been proven to be more successful at curing lung cancer than older 2-D radiation therapy for some patients with early stage lung cancer, according to a new study in a recent edition of the International Journal of Radiation Oncology, Biology, Physics.
Non-small cell lung cancer (NSCLC) accounts for 87 percent of all lung cancers diagnosed. Currently, the best treatment for stage I NSCLC is surgery or stereotactic radiation therapy (SRT), often followed by chemotherapy if the lesion is larger than 3 cm or radiotherapy and chemotherapy if the surgical margin or hilar or mediastinal nodes are positive at the time of operation. The five-year survival outcomes are very high, with 50 percent to 67 percent of these patients living at least five years after diagnosis if patients have a well-staged stage I NSCLC.
