Spontaneous Regression of Multiple Pulmonary Metastases of Advanced Renal Cell Carcinoma: A Case Report / 대한비뇨기과학회지

ABSTRACT

During an analysis of 27 patients cases of advanced renal cell carcinoma, eleven of which patients had pulmonary metastases. The case of a 53 year old male who underwent spontaneous regression of his lung metastases was found. This patient underwent right radical nephrectomy leaving some gross disease in the right lobe of the liver. Postoperatively regression was noted within 4 weeks and substantial decrease in the size of the metastatic lesions was noted before velban and Depoprovera were instituted 6 weeks after surgery. Complete disappearance of multiple pulmonary metastases was noted on the chest PA 8 weeks after surgery. At the time of the last clinic visit one year postoperatively, the pulmonary metastatic lesions had regressed entirely on the chest PA, leaving only micronodular hilar and Lt. lower lobe lesions on the chest CAT scan.
