Prevention of peritoneal metastasis of cancer with dextran sulfate???an experimental study in mice
1997
: Peritoneal metastases occur most often in the greater omentum, where tumor implantation sites are densely distributed. We used dextran sulfate (S-Dex) as an anti-cell-adherence agent to prevent i.p. seeded malignant cells from causing peritoneal metastases. S-Dex was tested for its anti-adherent activity against B-16 melanoma cells on plastic, and was examined for its ability to prevent implantation in the omentum and to improve survival in mice after B-16 melanoma was inoculated i.p. S-Dex prevented B-16 melanoma cells from adhering to the plastic wall. S-Dex reduced the number of B-16 melanoma cells implanted into the greater omentum and improved the survival of mice inoculated with B-16 melanoma cells. We conclude that S-Dex attenuated peritoneal metastases when B-16 melanoma cells were seeded i.p.
