Figure 1 Changes in lung lesions after nab-paclitaxel plus apatinib treatment. A: Computed tomography (CT) before treatment (baseline); B: CT scans after 6 cycles of nab-paclitaxel plus apatinib.

Figure 2 Needle biopsy of lung metastasis. A: Hematoxylin and eosin stain of tissue with tubular structures, and cells that are not significantly heteromorphic (original magnification × 200); B: Immunohistochemical staining of CK19 was strongly positive on tumor-cell membranes (original magnification × 200); C: Immunohistochemical staining of CA19-9 was strongly positive in tumor-cell cytoplasm (original magnification × 200).
