The resection margins were negative in the upper and lower tangent lines, and 0 of 6 peripheral lymph nodes had tumor metastases (Figure 2a). A soft tissue density was noted in the lower end of the walking area (Figure 2b). No cancer was detected at either end of the tangent line (Figure 2c). The pathologic diagnosis was urothelial carcinoma (Figure 2d).
Observation of small cell cancer: (a and b) enhanced chest CT scan findings of a right upper mediastinal mass, contrast medium was iohexol and (c) pathologic findings of a right upper mediastinal mass (small cell cancer).

In June 2019, a chest CT revealed multiple mediastinal lymphadenopathy (Figure 3a and b). An endoscopic ultrasonography guided fine needle aspiration was performed and small cell carcinoma was confirmed based on pathologic examination (Figure 3c).
Observation of LUSC: (a) enhanced chest CT scan findings of left lung mass, contrast medium was iohexol, (b) findings of fiberoptic bronchoscopy (mass in the lingual segment of the left upper pulmonary lobe), (c) pathologic findings of the LUSC, and (d and e) chest CT scan of the LUSC after treatment with apatinib, (e) enhanced chest CT, contrast medium was iohexol.

A enhanced chest CT showed that there was an irregular tissue mass in the lingual section of the left upper lobe near the hilum (Figure 4a). The surface of the mass was covered with milky white necrotic material (Figure 4b). The pathologic evaluation of the biopsy specimen revealed squamous cell carcinoma (Figure 4c). By October 2020, he was shown to have stable disease based on regular follow-up evaluations (Figure 4d and e).
