Abstract:
Objective To explore CT features of thin-wall cavity change of pulmonary metastases from renal clear cell carcinoma after molecular targeted treatment and its clinical significance.Methods Clinical and imaging data of 2 patients with thin-wall cavity of pulmonary metastases originating from renal clear cell carcinoma after molecular targeted drug Pazopanib were reported and analyzed retrospectively.Results After resection of primary renal tumors,multiple solid metastatic lesions in the lung were detected and the lesions showed ring enhancement on the post-contrast images.After 3-month Pazopanib treatment,most of the lesions presented thin-wall cavity change.Case 1 showed slowly disease progression while case 2 suffered from spontaneous pneumothorax and died 2 months later.Conclusion Necrosis of pulmonary metastases originated from renal carcinoma can be impelled by molecular targeted Pazopanib treatment,which helped to the formation of cystic thin-wall cavity,but the influence on the prognosis still remains uncertain.
