Patent Claims:	1. A method of treating a human being suffering from cancer selected from the group consisting of diffuse large B cell lymphoma (DLBCL), follicular lymphoma, chronic lymphocytic leukaemia, T cell lymphoma and Hodgkin lymphoma, wherein the method comprises the steps of: i) pretreating said human by administrating a HDAC inhibitor, a pharmaceutically acceptable acid or a salt thereof or a mixture thereof and a steroid or a pharmaceutically acceptable salt thereof, simultaneously or sequentially, wherein the HDAC inhibitor is selected from the group consisting of valproic acid or valproate semisodium, sodium valproate or magnesium valproate, and wherein the steroid is selected from the group consisting of prednisone, prednisolone, dexamethasone or betamethasone, and ii) treating said human by administrating a combination of cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP), or a combination of cyclophosphamide doxorubicin, vincristine, prednisone and CD20 antibody rituximab (R-CHOP), wherein said step of pretreating said human is performed 24-72 hours prior to said step of treating said human. 2. The method of claim 1, wherein the steroid is prednisone and the prednisone is selected is administered so as to achieve a serum concentration of 20 .mu.g/ml of its metabolite prednisolone in said human. 3. The method of claim 1, wherein the steroid is dexamethasone and the dexamethasone is administered so as to achieve a serum concentration of 1 .mu.M in said human. 4. The method of claim 1, wherein the HDAC inhibitor is valproic acid and wherein the steroid is prednisone. 5. The method of claim 4, wherein the valproic acid is administered so as to achieve a serum concentration of 0.5 mM to 1.5 mM in said human. 6. The method of claim 5, wherein the valproic acid is administered so as to achieve a serum concentration of 0.5 mM or 1.5 mM in said human. 7. The method according to claim 1, wherein said HDAC inhibitor and said steroid are combined in a pharmaceutical composition, said pharmaceutical composition being administered to said human. 8. The method according to claim 2, wherein said step of pretreating said human is performed 48 hours prior to said step of treating said human.
