Patent Claims:	1. A method of treating leukemia in a human, which comprises administering to a human having leukemia from about 1 to about 50 mg per day of 3-(4-amino-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione. 2. The method of claim 1, wherein the leukemia is chronic lymphocytic leukemia, chronic myelocytic leukemia, acute lymphoblastic leukemia, acute myelogenous leukemia or acute myeloblastic leukemia. 3. The method of claim 1, wherein the leukemia is relapsed, refractory or resistant to conventional therapy. 4. The method of claim 1, wherein the leukemia is chronic lymphocytic leukemia. 5. The method of claim 4, wherein the leukemia is refractory or relapsed chronic lymphocytic leukemia. 6. A method of treating leukemia, which comprises administering to a patient having leukemia from about 1 to about 50 mg per day of 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione and a therapeutically effective amount of a second active agent. 7. The method of claim 6, wherein the second active agent is antibody, hematopoietic growth factor, cytokine, anti-cancer agent, antibiotic, cox-2 inhibitor, immunomodulatory agent, immunosuppressive agent, corticosteroid, or a pharmacologically active mutant or derivative thereof. 8. The method of claim 6, wherein the second active agent is rituximab. 9. The method of claim 8, wherein the leukemia is chronic lymphocytic leukemia, chronic myelocytic leukemia, acute lymphoblastic leukemia, acute myelogenous leukemia or acute myeloblastic leukemia. 10. The method of claim 8, wherein the leukemia is chronic lymphocytic leukemia. 11. The method of one of claims 1-10, wherein the amount of 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione administered is from about 5 to about 50 mg per day. 12. The method of claim 11, wherein the amount of 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione administered is about 5, 10 or 25 mg per day. 13. The method of one of claims 1-10, wherein the amount of 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione administered is about 1, 2.5, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, or 50 mg per day. 14. The method of one of claims 1-10, wherein 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione administered is enantiomerically pure. 15. The method of claim 14, wherein 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione administered is S enantiomer. 16. The method of claim 14, wherein 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione administered is R enantiomer. 17. The method of one of claims 1-10, wherein 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione is administered in the form of a capsule or tablet. 18. The method of one of claims 1-10, wherein 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione is administered in an amount of about 25 mg per day for 21 days followed by seven days rest in a 28 day cycle. 19. The method of claim 18, further comprising administration of rituximab in an amount of 375 mg/m.sup.2. 20. The method of claim 6, wherein the second active agent is fludarabine. 21. The method of claim 20, wherein the leukemia is chronic lymphocytic leukemia. 22. The method of claim 1, wherein 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione is administered orally. 23. The method of claim 22, wherein 3-(4-amino-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione is administered in the form of a capsule. 24. The method of claim 23, wherein the compound is administered in the capsule of 5 mg, 10 mg, 15 mg or 25 mg. 25. The method of claim 23 or 24, wherein the capsule comprises the compound, lactose anhydrous, microcrystalline cellulose, croscarmellose sodium and magnesium stearate.
