Journal Article
An initial clinical study on the efficacy of cisplatin-releasing gelatin microspheres for metastatic liver tumors.
European Journal of Radiology 2009 September
PURPOSE: To evaluate the antitumor effect and side effects of cisplatin-releasing gelatin microspheres (Cis-GMSs) for metastatic liver tumors.
METHODS: Cis-GMSs that degraded over 14 days were employed. The subjects comprised a total of nine cases. Transcatheter hepatic artery embolization (TAE) using Cis-GMSs (Cis-GMSs-TAE) was performed 13 times in total. Six cases, each containing one to five tumors in a single segment to an entire lobe were treated by Cis-GMSs-TAE. In the remaining three cases with six or more metastatic liver tumors, the right and left lobes were treated by Cis-GMSs-TAE at a 2-week interval.
RESULTS: There were two complete response (CR), one partial response (PR) and six stable disease (SD) cases. The response rate was 33.3%. The average rate of reduction in tumor diameter was 32%. Disappearance of metastatic liver tumors was observed in only two of the nine cases. As for side effects and complications, post-embolization syndrome was observed in eight cases, but no severe complications such as cholangitis or liver abscess were observed.
CONCLUSION: Considering the mild side effects by Cis-GMSs-TAE, it is suggested that Cis-GMSs-TAE should be tried at least once as topical therapy for metastatic liver tumors when the response to systemic chemotherapy and other treatments is not satisfactory.
