Most children with acute lymphoblastic leukemia (ALL) are successfully treated by chemotherapy. For those patients, who relapse on therapy, bone marrow transplantation (BMT) is considered most appropriate after a subsequent remission is achieved. Three boys with ALL aged from 9 to 13 years met these criteria and received BMT from their HLA-compatible sisters after marrow ablation with total body irradiation 12 Gy plus high dose cytosine arabinoside 3 gm/m2/12h x 12 doses and graft-versus-host disease (GVHD) prophylaxis with cyclosporine plus short course methotrexate from March 10, 1989 to May 23, 1992. Filgrastim (rhG-CSF) was used to hasten the recovery of granulocyte in one patient. All three patients got full engraftment and two had grade 1 acute GVHD. None of them developed chronic GVHD. Two patients have disease-free survival over 51 and 12 months respectively post BMT without further chemotherapy. One patient died of recurrent refractory leukemia 5 months after BMT. The toxicity of this conditioning regimen included photophobia, conjunctivitis and erythematous skin rashes. One patient who received filgrastim from day 1 to 21 developed severe bone pain. However, this patient had faster recovery of granulocyte count than the other two patients. The preliminary results of this work favors BMT for children with recurrent ALL whose ultimate survival is usually poor when treated with chemotherapy. Further efforts are necessary to investigate new methods for reducing leukemic relapse in ALL patients undergoing BMT.

From 1977 to 1990, 40 cases of bone marrow necrosis (BMN) were diagnosed among 10,856 (0.37%) consecutive bone marrow aspirations performed alone or with biopsy. All but two patients had underlying malignancies. Leukemia, nasopharyngeal cancer and cancer of unknown origin were the most common underlying diseases. Severe bone pain and fever were the predominant presenting symptoms. Anemia, schistocytes and leukoerythroblastosis were noted in the peripheral blood smears in 97% (37/38), 72% (22/32), and 66% (23/35) of the patients with cancer and BMN. Malignant cells were found in bone marrow aspirates or biopsy specimens in all but one of the patients. Varied degrees of disseminated intravascular coagulation were demonstrated in all of the 10 patients examined who displayed coagulation status. Four of seven patients with leukemia achieved complete remission after chemotherapy, and the survival time for the complete responders ranged from 10 months to eight years. The outcome of cancer patients with BMN who did not respond to chemotherapy was poor, with a median survival time of six weeks.

We treated 70 acute promyelocytic leukemia (APL) patients with daily oral 45 mg/m2 all-trans-retinoic acid (ATRA) in two multi-institutional prospective studies. Of 64 evaluable patients, 21 were refractory to initial induction chemotherapy; 10 were refractory to salvage chemotherapy; 17, five, and four were in the first, second and, third relapse, respectively; and seven were previously untreated due to old age. In the first study with ATRA from China, 18 out of 22 (82%) evaluable patients achieved complete remission (CR). Initial peripheral leukemia cell counts were significantly less in the CR cases (p < 0.01); < 100/microliters in 17 out of 18 CR cases, and > or = 200/microliters in all failure cases. In the second study with ATRA from Hoffmann-La Roche, if initial leukemia cell counts were more than 200/microliters, chemotherapy was first given and then ATRA was started. Of 42 evaluable patients, 36 (86%) achieved CR. Morphological evidence of differentiation was noted in all CR cases. Patients achieving CR received standard consolidation and maintenance chemotherapies, and the 20-month predicted disease-free survival rate is 76% for cases achieving their first CR with ATRA. Toxicities attributable to ATRA were minimal and included cheilitis, xerosis, dermatitis, gastrointestinal disorders, bone pain, liver damage, and high serum triglyceridemia.

High dose methylprednisolone (HDMP) has been used in induction treatment and in leukopenia of acute leukemia. We report the case of a 14-year-old girl with acute myelomonocytic leukemia (AMML) who developed a pseudorelapse after receiving an oral HDMP trial (30 mg/kg/day PO in the morning for 15 days) to overcome neutropenia. She presented with severe bone pain at the end of treatment. Bone marrow examination revealed 53% young promyelocytes (some with a large nucleolus), 2% myeloblast, 5% monocyte, and increased cellularity. Bone pain and promyelocytes regressed spontaneously while maintenance treatment continues. We advise that a pseudorelapse must be borne in mind after HDMP and probably GM-CSF treatments in acute leukaemias.

We treated 70 patients with acute promyelocytic leukemia (APL) with daily oral 45 mg/m2 all-trans retinoic acid (ATRA) in 2 multi-institutional prospective studies. Of 63 evaluable patients, 21 were resistant to initial induction chemotherapy, 10 were resistant to salvage chemotherapy after relapse, 17 were in the first relapse, 4 in the second relapse, 4 in the third relapse, and 7 were previously untreated. In the first study with ATRA from China, 18 (82%) of 22 evaluable patients achieved CR within 8 to 53 days with a median of 29 days. Initial peripheral leukemia cell counts were significantly less in the CR cases (p < 0.01). They were less than 100/mm3 in 17 of 18 CR cases, and more than 200/mm3 in all failure cases. Patients achieving CR received standard consolidation and maintenance chemotherapies, and the 16-month predicted continuing CR rate is 60%. Based on the first study, in the second study with ATRA from Hoffmann-La Roche AG, if initial peripheral leukemia cell counts were more than 200/mm3, chemotherapy was first given and then ATRA was started. Of 41 evaluable patients, 36 (88%) achieved CR within 11 to 91 days with a median of 34 days. Of 3 patients who received preceding chemotherapy due to high leukemia cell counts, 2 achieved CR. Morphological evidence of differentiation was noted in all CR cases, with Auer rods in mature segmented neutrophils in 13 cases. The clinical signs of DIC decreased rapidly within a few days and disappeared in CR cases. Toxicities attributable to ATRA were minimal and included cheilitis, xerosis, dermatitis, gastrointestinal disorders, bone pain, liver damage and high serum triglyceridemia.

Patients with AML who relapse after an initial remission, have a poor prognosis. Administration of hemopoietic growth factors (HGFs) such as interleukin-3 (IL-3) during chemotherapy may result in an increased cell kill by cytotoxic agents. In addition, administration of IL-3 following chemotherapy may potentially accelerate hemopoietic recovery from chemotherapy-induced bone marrow hypoplasia. We performed an open labelled, phase I/II study in which patients received IL-3 by continuous infusion from 24 h before the beginning of chemotherapy until day 28. Chemotherapy included daunorubicin or mitoxantrone days 1-3 and cytarabine 200 mg/m2 days 1-7. IL-3 was given at a dose of 5 microgram(s)/kg/day in 10 patients, 7.5 microgram(s)/kg /day in six patients and 10 microgram(s)/kg/day in four patients. Complete remissions (CR) after one cycle of this treatment were obtained in 5/10 patients and 5 microgram(s)/ kg group, 2/6 in the 7.5 microgram(s)/kg group and 3/4 in the 10 microgram(s)/kg group). Thus, 50% (10/20) of all individuals and 45% (5/11) of the elderly patients attained CR. Eight of 20 patients entered PR, and 2/20 patients died during the hypoplastic phase from infectious complications. Neutrophils and platelets recovered to 0.5 x 10(9)/l at day 25 (median) and to 50 x 10(9)/l at day 32, respectively. Adverse events during IL-3 and concomitant chemotherapy were fluid retention (4/20), rash (14/20), bone pain (2/20), headache (10/20), chest pain (1/20), arthritis (1/20), fever and nausea. IL-3 (at the dose of 10 microgram(s)/kg) was discontinued in two patients because of side-effects (fluid retention, fever, rash and chest pain), and in two other patients the high IL-3 dose was tolerated with no problems for 29 days. Thus, IL-3 applied to patients with high-risk AML at dosages of 5-10 microgram(s)/kg is tolerated with acceptable toxicity and results in a satisfactory frequency of complete responses following a single treatment cycle.

A number of cytokines are used as haemopoietic growth factors and this review focuses on toxicities associated with granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF), interleukin (IL)-1, IL-3, IL-4, IL-6 and macrophage colony-stimulating factor (M-CSF). Both GM-CSF and G-CSF, currently approved for clinical use, are generally well tolerated by the majority of patients during short term administration. Constitutional symptoms and bone pain are the most frequently reported adverse effects, but they are rarely treatment-limiting. Reactivation of rheumatoid symptoms, and exacerbation of autoimmune thyroiditis or autoimmune haematological disorders have sometimes been described. Severe cardiovascular complications include the possibility for arterial thromboses and the vascular leak syndrome, which is more specifically observed with GM-CSF. Reports of several cases and small series of patients have suggested that growth factors might increase the pulmonary toxicity of chemotherapy, a possibility that remains debated and requires further attention. Generalised or local cutaneous reactions are frequently noted with GM-CSF. Leukocytoclastic vasculitis was observed with both growth factors, while neutrophilic dermatoses have been mostly described with G-CSF. Exacerbation of psoriasis and isolated anaphylactic reactions have appeared with GM-CSF and G-CSF. The hepatotoxic potential of the growth factors is not clearly established, but the occurrence of coagulation abnormalities has recently been reported. Renal and biological disturbances are usually transient. Long term treatment with GM-CSF and G-CSF also seems to be well tolerated, but the possible occurrence of several adverse events, i.e. bone disorders, leukaemia, unmasking or acceleration of underlying disease, require further investigation in patients receiving prolonged treatment, as in myelodysplasia. Finally, antibodies against growth factors have been reported only with GM-CSF. Other cytokines are still under investigation. Flu-like and constitutional symptoms, sometimes dose-limiting, have been reported with IL-1, IL-3, IL-4 and IL-6, while M-CSF was occasionally associated with such adverse effects. More specific adverse events, also frequently considered as dose-limiting toxicities, include hypotension with IL-1, severe headache or skin rash with IL-3, and nasal congestion and gastroduodenal lesions with IL-4. Severe capillary leak syndrome has been reported only with IL-4. M-CSF toxicity is minimal and limited to reversible but sometimes dose-limiting thrombocytopenia and ophthalmological symptoms with the recombinant product. Again, the safety of long term administration of these cytokines has not yet been determined, and IL-3-induced disease progression in myelodysplastic patients has been suggested.

Six patients with high-risk leukaemia received a myeloablative regimen followed by allogeneic peripheral blood progenitor cells transplantation (PBPCT) from an HLA-identical sibling donor. Donors received 10-12 mu g/kg/day of G-CSF subcutaneously for 5 days. G-CSF was well tolerated except for moderate bone pain. Peripheral blood leukapheresis product contained 1-4 times more CD34+ cells and approximately a log more of T lymphocytes than marrow grafts from normal donors. In the two first cases the leukapheresis product was partially depleted of T-lymphocytes using counterflow centrifugation. No growth-factors were administered post-transplant. GVHD prophylaxis consisted of cyclosporin A (CyA) in one case, and CyA and methotrexate in five cases. All patients engrafted with a neutrophil count reaching more than 0.5 x 10(9)/L by day 12 to 21 post-transplant and a platelet count above 20 x 10(9)/L by day 6 to 41 post-transplant. Acute GVHD was clinical grade 0 (n = 2), I (n = 1), II (n = I), grade III (n = I) and grade IV (n = 1). One case presents an extensive chronic cutaneous GVHD and is currently being treated with methylprednisolone. In conclusion, allogeneic transplants using PBPC can be performed safely. This may result in a rapid neutrophil and platelet engraftment, without an apparent increased risk of GVHD.
