Selective bronchial angiography was performed in 26 patients with bronchogenic carcinoma in connection with intraarterial infusions of cytostatic drugs. The angiographic extension of the tumor was correlated to data obtained at surgery, mediastinoscopy or autopsy. Bronchial angiography is not suitable as a routine procedure in the preoperative evaluation of patients with bronchogenic carcinoma but may contribute to a more precise staging of the tumor.

Bronchial artery infusion of mitomycin C might be very effective in treating minor tumors but, as a rule, less effective in the treatment of larger tumors. In order to achieve improved effect of treatment, 21 cases (stage II-III/TNM) were given supplementary chemotherapy with bleomycin or vincristine-bleomycin. Preoperative treatment was given to 11 cases in which indications for surgical treatment were primarily uncertain or absent. The other group consisted of 10 patients with inoperable lesions. Combined treatment has proved to have a strong but mainly local effect. Repeated courses (up to 5 times) were more effective than a single one. The regional effect, i.e: on overgrowth onto the mediastinum, pericardium or thoracic wall was weak. The system effect was negligible. Penetrating data about objective response are given.

Bronchial angiography was performed in 17 patients with advanced non-oat cell bronchogenic carcinoma. The patients were treated 1 to 5 times with infusions of 10 mg of mitomycin-C (MMC) into the tumor-feeding bronchial artery. All but 2 patients received in addition small doses of vincristine (intravenously) and bleomycin (intramuscularly) or only bleomycin to potentiate the effect of MMC. No major side effects occurred and the systemic toxicity was insignificant. An objective tumor reponse was encountered in 11/17 patients. Intraarterial chemotherapy is strictly local and therefore effective especially in patients with limited or locally advanced disease. In patients with more extensive disease an adjunctive therapy of a more regional or systemic modality must be given.

Celiac and/or superior mesenteric angiography was done routinely in association with renal angiography on 115 patients with renal cell carcinoma. Metastases were demonstrated in 20 patients on extended angiography. In 10 of these patients no other signs of metastatic disease were noted at diagnosis. In the total clinical diagnostic stydy metastatic spread was present in 41 patients.
