[Therapeutic results of the internal iliac arterial chemotherapy in uterine cervical and endometrial cancers].

As the treatment of inoperable, radioresistant or recurrent cases of uterine cancer (cervical or endometrial) whose lesions were restricted to the pelvis, internal iliac arterial chemotherapy was carried out and its therapeutic results were evaluated. Thirty three cases including 22 primary and 11 recurrent ones were dealt with this study. Among 33 cases, catheter was introduced to the internal iliac artery via superior gluteal artery in 9, inferior gluteal artery in 22 and lateral umbilical artery in 2 cases. Oncostatics, including mainly cisplatin, adriamycin and pepleomycin, were administered via artery daily or once or three times a week with indwelling of the catheter as long as 7 months in average. Eight patients out of 33 were living with average survival time of 18.2 months following the initiation of intra-arterial chemotherapy. Among 27 cases whose therapeutic effects were evaluable histologically, tumor cells had disappeared as long as at least 4 months in 23, within 4 months in 3 cases and tumor cells continued to be present in one case. In 22 primary cases, 3 were living without evidence of disease, one was living with disease and remaining 18 cases were dead due to other diseases in two cases, distant metastasis in 7 cases, troubles of the primary site in 8 cases and unknown reason (septic shock?) in one case. Four of 11 recurrent cases were living with one case of tumor bearing state. Complete response (CR) was obtained in 5 cases and partial response (PR) in 4 among 9 evaluable recurrent cases. As for the recurrent cases whose main therapy was intra-arterial chemotherapy only, CR was gained in 3 and PR was got in 4 out of 7 cases. Severe side effects were observed in 11, moderate one in 15 and mild one in 6 cases.
