Abstract

The invention relates to methods for preventing and treating disseminating cancers. Inhibition metastases of a primary tumor to a liver tissue is carried out by directly contacting a liver tissue with Taurolidine.

Claims

1. A method of inhibiting metastases of a primary tumor to a liver tissue, comprising directly contacting said liver tissue with taurolidine.

2. The method of claim 1, wherein said primary tumor is not a liver tumor.

3. The method of claim 1, wherein said primary tumor is in an organ of the peritoneal cavity.

4. The method of claim 1, further comprising identifying an individual who is at risk of developing a metastatic liver tumor.

5. The method of claim 4, wherein said individual is a mammal.

6. The method of claim 5, wherein said mammal is a human.

7. The method of claim 1, wherein said individual is identified as suffering from a colorectal tumor.

8. The method of claim 1, wherein said individual is identified as suffering from a tumor selected from the group consisting of a lung tumor, breast tumor, kidney tumor, colon tumor, esophageal tumor, testicular tumor, pancreatic tumor, melanoma, and choriocarcinoma.

9. The method of claim 1, wherein said liver is isolated from systemic circulation prior to contacting with said Taurolidine.

10. The method of claim 1, wherein said liver is perfused with said taurolidine in situ.

11. The method of claim 1, wherein liver blood circulation is essentially isolated from systemic blood circulation.

12. The method of claim 1, wherein said perfusion is performed prior to excision of a primary tumor.

13. The method of claim 1, wherein said perfusion is carried out in conjunction with an abdominal surgery.

14. The method of claim 1, wherein said Taurolidine is administered by in-dwelling catheter.

15. The method of claim 1, wherein said Taurolidine is administered at a dose which increased caspase activity in a cell.

16. The method of claim 1, wherein said Taurolidine is administered intravenously.
