The present AML protocol which only applies one anthracycline associated with arabinosyl-cytosine gives a first remission plateau of 65% and a 75% survival plateau at five years. Contrary to other teams, we do not apply the allogenic bone marrow graft at the first remission but at the second one. The new protocol comprises application of two anthracyclines, adriamycin and aclacinomycin, a possible autologous bone marrow graft at first remission upon reinforcement, a combination of methotrexate and thioguanine as maintenance chemotherapy and immunotherapy with bestatine. The two protocols respectively applied to the ALL good prognosis and reserved prognosis, give 85% global survival. The autologous bone marrow graft is added at first remission to B or T forms or voluminous CALLA + types. The advantage of CNS radiotherapy is compared with its disadvantages. Bestatine is employed in immunotherapy. The immunoprevention protocol applied to CML blastic crisis (vaccination with a pool of CB blasts) from the second year has prolonged survival of patients suffering from this affection and also treated by splenectomy and hydroxyurea. Allogeneic or autologous bone marrow graft is added to the protocol. The same protocol is applied to not very aggressive LLC and LNH (lymphocytic and centrofollicular with small cleaved nucleus cells) and includes maximum remission induced by chemotherapy followed by immunotherapy (by thymuline and then, if immunity disorders are not corrected, by zinc, then bestatine and finally tuftsin). A similar sequence was applied to the myeloma, comprising MLP-PDN-CPM chemotherapy to induce remission, combination of MLP-PDN and CPM and, if there is resistance, CLB, 6-TG, PDN and TNP. Interferon is appropriate with certain cytopenic forms. A protocol comprising VCR, ADM, PDN, CPM and TNP is applied to centrofollicular NHL with small non cleaved nucleus cells or large cells. As Hoerni and Jones have obtained significant benefits with BCG, its terminal application is compared with that of bestatine. Finally a less mutagenic protocol than MOPP and/or ABVD is proposed for Hodgkin's disease. In this protocol, two cycles alternate, and they combine: a) firstly VCR, PDN, THP-ADM and VPS, and b) secondly VLB, DXM, ACM and TNP with alternatively BLM and PPM between the cycles. This chemotherapy is followed by the same immunorestoration protocol as that applied to LLC and myeloma.

Studies performed on mice and healthy human volunteers have shown that a single dose of pegfilgrastim (Peg-GCSF) is effective in stimulating peripheral blood stem cells (PBSC) mobilization. This prompted us to try the stimulation with pegfilgrastim in a patient previously non-mobilizing with a combination of chemotherapy and filgrastim. In December 2003, a 65-yr-old man was diagnosed as having stage III A IgG/k multiple myeloma. He received three courses of polichemotherapy (DC-IE) obtaining a stable response. Afterwards, the patient was treated with high-dose cyclophosphamide (CPM; 7 g/sqm) plus daily 10 mcg/kg filgrastim in order to mobilize PBSC, without success. After 2 months off therapy, the disease progressed and the patient received alternate cycles VAD (vincristine, dexamethasone, adriblastine)/high-dose dexamethasone. A second attempt to mobilize PBSC, using daily 10 mcg/kg filgrastim after the second and third VAD cycle, failed. In a further attempt to mobilize PBSC, we administered a single dose of 12 mg pegfilgrastim on day 5 after a fourth VAD course. Daily evaluation of circulatory CD34+ cells was started from day 8 after the end of chemotherapy. On day +10 postchemotherapy the CD34+ cell count was 24/microL and two aphaeresis were performed, harvesting 1.6 x 10(6) and 0.89 x 10(6) CD34+ cells/kg respectively (total 2.49 x 10(6) cells/kg). The only side effect was moderate skeletal pain. The patient underwent successful transplantation. The median times necessary to recover 0.5 x 10(9) PMN/L and 20 x 10(9) platelets/L after PBSC reinfusion were 9 and 12 d respectively. The patient did not need red blood cell or platelet transfusions. He experienced a sustained engraftment and maintains complete remission 9 months after the reinfusion. In conclusion, a single dose of pegfilgrastim was able to mobilize a sufficient number of CD34+ in a multiple myeloma patient not responsive to two previous attempts with high or standard dose chemotherapy followed by filgrastim. This approach, if confirmed on larger series and other diseases, could open new opportunities in stem cell mobilization for poor or non-mobilizers.
