Sixty-nine patients received CIRT with a total dose of 72.0 GyE given in 9 fractions and 80 patients treated with 60.0 GyE in 4 fractions.Amongthem,we selected 43 cases who survived 5 years or longer and were judged as free of local recurrence, for whom changes in the shadows at the tumor site were analyzed on CT scans before and after CIRT. IN 38 of 43 cases(88.4%),the shadow was fixed within 2 years;while in the remaining 5 cases, the shadow was fixed within 2 to 4 years. In most cases examined, the changes in the shadows on CT tended to fix within 2 years after CIRT.this finding appeared usefull for estimating the local control in the follow-up after CIRT., H21年度HIMAC共同利用研究成果発表会}, title = {非小細胞肺癌重粒子線治療後のCT画像の変化と局所制御の関連性についての検討}, year = {2010} }
