| 内容記述 | In order to evaluate the characteristics of changes in tumor shadow on CT images and the pulmonary response after carbon ion radiotherapy (CIRT) for non-small cell lung cancer, we examined the CT images for those with long-term local control and evaluated if there were any changes in the shadow at the tumor site on CT before and after CIRT. In our institute, 69 patients received CIRT more than 8 years ago with a total dose of 72.0 GyE given in 9 fractions. Among them, we selected 27 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 23 of 27 cases (85.2%), the shadow was fixed within 2 years; while in the remaining 4 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 useful for estimating the local control in the follow-up after CIRT. |
