Three patients with lung metastases of urogenital tumors were treated by bronchial arterial infusion therapy. Case 1: A 52-year-old man who had multiple lung metastases of right renal cell carcinoma fell into a dyspnea at 5 months after right radical nephrectomy. Though the effects of resection or laser coagulation with bronchoscopy were temporary, two sessions of BAI therapy with radiation improved the symptom of dyspnea for at least 3 months. Case 2: A 53-year-old man who had multiple lung metastases of right renal cell carcinoma was treated with systemic chemotherapy after right radical nephrectomy. Because the systemic chemotherapy showed only minor response, two sessions of BAI therapy were performed. No lung metastasis was detected in radiographs for 2 years after BAI therapy. Case 3: A 69-year-old man who had multiple lung metastases of left ureteral tumor was treated with 3 sessions of systemic chemotherapy. Though the systemic chemotherapy was effective, 2 sessions of BAI therapy with radiation showed a more suppressive effect, and the regrowth was not detected for 7 months after the therapy was performed. We concluded that BAI therapy was an effective therapeutic method not only for cases with no operative indication, but also for cases in which systemic chemotherapy was not effective.
