Application Number:	14/781,898
Patent Claims:	1. A method of increasing macrophages or natural killer cells in tumor microenvironment in a human having a central nervous system cancer, which comprises administering to a human in need thereof a therapeutically effective amount of 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione. 2. The method of claim 1, wherein the cancer is relapsed, refractory or resistant to conventional therapy. 3. The method of claim 1, wherein the cancer is primary central nervous system lymphoma ("PCNSL"), primary vitreoretinal lymphoma ("PVRL"), intra-ocular lymphoma, central nervous system blastoid mantle cell lymphoma, a central nervous system tumor, a central nervous system solid tumor, neuroblastoma, a central nervous system cancerous condition, mantle cell lymphoma ("MCL"), lymphocytic lymphoma of intermediate differentiation, intermediate lymphocytic lymphoma ("ILL"), diffuse poorly differentiated lymphocytic lymphoma ("PDL"), centrocytic lymphoma, diffuse small-cleaved cell lymphoma ("DSCCL"), follicular lymphoma, or mantle zone lymphoma. 4. The method of claim 1, where the cancer is a neuroepithelial tumor, a tumor of meninges, a nerve sheath tumor, glioblastoma, or astrocytoma. 5. The method of claim 4, wherein the cancer is a neuroepithelial tumor, and wherein the neuroepithelial tumor is an ependymal tumor. 6. The method of claim 1, wherein the cancer is a tumor of meninges, a neuroepithelial tumor, a nerve sheath tumor, glioblastoma, astrocytoma, a central nervous system lymphoma, hemangioma, or neoplasm. 7. The method of claim 6, wherein the cancer is a tumor of meninges. 8. The method of claim 1, wherein the cancer is located at meninges, pituitary, pineal, nasal cavity, frontal lobe, temporal lobe, parietal lobe, occipital lobe, cerebrum, ventricle, cerebellum, brain stem, spinal cord, cauda equina, or cranial nerves. 9. The method of claim 1, wherein the cancer is meningioma, glioblastoma, a tumor of the pituitary, a nerve sheath tumor, a neuroepithelial tumor, craniopharyngioma, a central nervous system lymphoma, a germ cell tumor, astrocytomas, oligodendrogliomas, or an embryonal tumor. 10. The method of claim 1, wherein the cancer is glioma. 11. The method of claim 10, wherein the glioma is glioblastoma, astrocytoma, an oligoastrocytic tumor, oligodendroglioma, an ependymal tumor, or glioma malignant NOS. 12. The method of claim 1, where the cancer is a central nervous system lymphoma. 13. The method of claim 12, where the central nervous system lymphoma is primary central nervous system lymphoma ("PCNSL"). 14. The method of claim 1, wherein the amount of 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione administered is from about 0.1 to about 5 mg per day. 15. The method of claim 14, wherein the amount of 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione administered is about 1, 2, 3 or 4 mg per day. 16. The method of claim 15, wherein the amount of 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione administered is about 4 mg per day. 17. The method of claim 14, wherein 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione administered is enantiomerically pure. 18. The method of claim 17, wherein 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione administered is S enantiomer. 19. The method of claim 17, wherein 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione administered is R enantiomer. 20. The method of claim 14, wherein 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione is administered orally. 21. The method of claim 20, wherein 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione is administered in the form of a capsule or tablet. 22. The method of claim 14, wherein 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione is administered for 21 days followed by seven days rest in a 28 day cycle. 23. The method of claim 22, wherein 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione is administered in an amount of from about 1 mg to about 4 mg per day for 21 days followed by seven days rest in a 28 day cycle. 24. The method of claim 23, further comprising administration of rituximab in an amount of 375 mg/m.sup.2 by intravenous infusion weekly. 25. A method of increasing macrophages or natural killer cells in tumor microenvironment in a human having a central nervous system cancer, which comprises administering to a patient in need thereof a therapeutically effective amount of 4-amino-2-(2,6-dioxo-piperidine-3-yl)-isoindoline-1,3-dione and a therapeutically effective amount of a second active agent. 26. The method of claim 25, 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. 27. The method of claim 25, wherein the second active agent is rituximab.
