A, a nodule in the right upper lobe; B, a nodule in the middle lobe. Each scale bar indicates 100 μm. (C, D) Computed tomography and histopathology of the (C) previous lung cancer and (D) the pancreatic cancer. The arrow indicates the pancreatic cancer. Each scale bar indicates 100 μm. (E) Heatmap of the gene mutations of the three lung tumors and the pancreatic cancer.
