Abstract

Purpose

To develop a drug-delivery system for the prolonged retention of intraperitoneally (i.p.) administered cisplatin (CDDP) to deliver intraperitoneal chemotherapy against peritoneal carcinomatosis effectively.

Methods

CDDP was encapsulated inside an in situ cross-linkable hyaluronic acid (HA)-based hydrogel. The gelation and degradation kinetics of the hydrogel and the release kinetics of CDDP were investigated in vitro, and the antitumor effect was investigated in a mouse model of peritoneal dissemination of human gastric cancer.

Results

The gelation time varied according to the concentration of two polymers: HA-adipic dihydrazide and HA-aldehyde. CDDP was released from the hydrogel for more than 4 days. A cell proliferation assay showed that the polymers themselves were not cytotoxic toward MKN45P, a human gastric cancer cell line. By mixing the two polymers in the peritoneum, in situ gelation was achieved. The weight of peritoneal nodules decreased in the hydrogel-conjugated CDDP group, whereas no significant antitumor effect was observed in the free CDDP group.

Conclusions

In situ cross-linkable HA hydrogels represent a promising biomaterial to prolong the retention and sustain the release of intraperitoneally administered CDDP in the peritoneal cavity and to enhance its antitumor effects against peritoneal dissemination.
