[Studies of intra-arterial hypertensive chemotherapy with cisplatin and peplomycin in advanced cancer of the uterine cervix--suitable dose of angiotensin II determined by intra-arterial digital subtraction angiography].
We have been treating advanced cancer of the cervix uteri with intra-arterial cisplatin (CDDP) and peplomycin (PEP) (injected into the bilateral internal iliac artery), combined with radiotherapy and hysterectomy. Concomitant angiotensin II (ATII) administered by intravenous drip infusion was found to double tumoral blood flow and thereby to enhance the efficiency of the intra-arterial chemotherapeutic regimen. In the present study, hypertensive intra-arterial chemotherapy utilizing ATII was administered to a small group of patients with advanced cancer of the cervix uteri while ascertaining the increase in intratumoral blood flow by intra-arterial digital subtraction angiography. The subjects were 10 patients with stage IIb or more advanced cancer of the cervix uteri.


RESULTS
A 2-fold or greater increase in tumoral blood flow was attained in those patients who showed concurrently a 1.5 fold or greater increase in mean blood pressure and an increase in mean blood pressure to 150mmHg or higher. In 2 patients, ATII infusion failed to raise blood pressure to a therapeutically adequate level. At 1 week after the treatment in question histological evidence indicated unequivocal degenerative changes and necrotic changes in tumor cells. Many plasma cells, lymphocytes + and granulocytes appeared around necrosis changed carcinoma nests.
