What is claimed is: 
     
         1 . A method for killing a cancer cell expressing an amount of a chemokine sufficient to produce a fugetactic effect, which method comprises:
 a) periodically contacting said cell with an effective amount of an anti-fugetactic agent for a sufficient period of time so as to inhibit said fugetactic effect;   b) contacting said cell with at least one anti-cancer agent, wherein steps a) and b) are done in sequential order; and   c) optionally repeating steps a) and b) as necessary to kill said cell.   
     
     
         2 . The method of  claim 1 , wherein said chemokine is CXCL12 or interleukin 8. 
     
     
         3 . The method of  claim 1 , wherein said cancer cell is a solid tumor cell. 
     
     
         4 . The method of  claim 1 , wherein said cancer cell is a leukemia cell. 
     
     
         5 . The method of  claim 1 , wherein said anti-fugetactic agent is selected from the group consisting of AMD3100, KRH-1636, T-20, T-22, T-140, TE-14011, T-14012, TN14003, TAK-779, AK602, SCH-351125, Tannic acid, NSC 651016, thalidomide, and GF 109230X.

         17 . A method for killing a cancer stem cell in a mammal, the method comprising administering to said mammal an effective amount of an anti-fugetactic agent for a sufficient period of time so as to induce said cancer stem cell to enter the circulatory system of the mammal, followed by administering to said mammal an effective amount of at least one anti-cancer agent to kill the cancer stem cell. 
     
     
         18 . The method of  claim 17 , wherein said anti-fugetactic agent is selected from the group consisting of AMD3100, KRH-1636, T-20, T-22, T-140, TE-14011, T-14012, TN14003, TAK-779, AK602, SCH-351125, Tannic acid, NSC 651016, thalidomide and GF 109230X.
