Filing Date:	Sep 30, 2005
Application Number:	11/239,704
Claims:	1. A method of treating a solid tumor comprising administering to a human patient having a solid tumor a therapeutically effective amount of arsenic trioxide, wherein the solid tumor is a cancer of the digestive tract, esophagus, liver, stomach, colon, brain, bone, breast, or lung or is a sarcoma. 2. The method of claim 1, wherein the solid tumor is a sarcoma. 3. The method of claim 2, wherein the sarcoma is prostate cancer. 4. The method of claim 1 wherein the amount of arsenic trioxide administered is about 1 mg to about 40 mg per day. 5. The method of claim 1, wherein the therapeutically effective amount of arsenic trioxide is based on the weight of the patient. 6. The method of claim 5, wherein the therapeutically effective amount of arsenic trioxide is about 0.1 to about 5.0 mg/kg body weight of the patient. 7. The method of claim 6, wherein the therapeutically effective amount of arsenic trioxide is administered to the patient daily for five days. 8. The method of claim 7, wherein the daily administration of arsenic trioxide for five days is repeated once per month until tumor growth is inhibited or until the tumor shows signs of regression. 9. The method of claim 5, wherein the therapeutically effective amount of arsenic trioxide is about 0.15 mg of arsenic trioxide per kg of body weight of the patient per day. 10. The method claim 1 wherein the solid tumor is a cancer of the digestive tract. 11. The method of claim 1 wherein the solid tumor is a cancer of the esophagus. 12. The method of claim 1 wherein the solid tumor is a cancer of the liver. 13. The method of claim 1 wherein the solid tumor is a cancer of the stomach. 14. The method of claim 1 wherein the solid tumor is a cancer of the colon. 15. The method of claim 1 wherein the solid tumor is a cancer of the brain. 16. The method of claim 1 wherein the solid tumor is a cancer of the bone. 17. The method of claim 1 wherein the solid tumor is a cancer of the breast. 18. The method of claim 1 wherein the solid tumor is a cancer of the lung. 19. The method of claim 1, comprising administering the therapeutically effective amount of arsenic trioxide to the patient in combination with a chemotherapeutic agent. 20. The method of claim 1, comprising administering the therapeutically effective amount of arsenic trioxide to the patient in combination with radiation treatment. 21. The method of claim 1, wherein the solid tumor is refractory to other therapy. 22. The method of claim 1, wherein the arsenic trioxide is administered intravenously.
