Advances In Stereotactic Body Radiotherapy For Early Stage Non-small-cell Lung Cancer

According to the 2015 China cancer statistics,lung cancer is a malignant tumor with the highest morbidity and mortality in China,its levels of both morbidity and mortality are similar to that in the developed countries.While only few patients can get early treatment through early physical examination.As the main pathological type in lung cancer,the treatment for early stage non-small-cell lung cancer(NSCLC)has great clinical value.At present,stereotatic body radiotherapy(SBRT)and surgery are the main treatment strategies for early stage NSCLC.SBRT with excellent overall survival and local control rates,by the advances of radiation physical technologies,just like respiratory motion control and image-guided technology,has been the standard alternative treatment for inoperable patients.The widely use of SBRT benefits many patients and presents the challenge,whether SBRT is adequate effective to take place of surgery in operable NSCLC patients.The dose prescription of SBRT,and the influence of tumor location on SBRT,there still are many unsolved questions needing plenty of researches to clarify.
