| Research Abstract |
Treatment effect of neoadjuvant chemoradiotherapy (NACRT) and diagnosis ability of imaging was revealed by analyzing the diagnostic imaging before and after NACRT and pathological diagnosis of surgical specimens of locally advanced non-small cell lung cancer. Complete remission (CR) was observed in 6 among 11 cases. Fifty to 80% of morphologically viable cells of the non-CR cases showed double strand breaks of DNA and decreased the proliferating index. Results of analyses of imaging diagnosis showed that reduction rate of 18F-fluorodeoxy glucose uptake and disappearance of high signal intensity on diffusion weighted image reflected the good treatment effect. The present study showed efficacy of NACRT and the potential that a functioning image leads to the tailor-made treatment.
