Figure 1 (A) Contrast-enhanced computed tomography (CECT) image showing liver metastasis in the right posterior segment at the first detection. (B) Chest computed tomography (CT) image showing intrapulmonary metastasis in the right lower lobe at the first detection. (C) Noncontrast chest CT image before nivolumab treatment showing the tumor growth compared with before chemotherapy. (D) Chest CT image before nivolumab treatment showing the increase in size of the intrapulmonary metastasis versus before chemotherapy. (E) CECT image after nivolumab treatment showing further tumor growth versus before treatment. (F) Chest CT image after nivolumab treatment showing a slight increase in size versus before treatment. (G) CECT image at 3 weeks after radiotherapy completion showing the substantial tumor shrinkage. (H) Chest CT image at 3 weeks after completion of radiotherapy showing the marked shrinkage of intrapulmonary metastasis (which was not irradiated), demonstrating the abscopal effect.
