A 62-year old male was admitted to our hospital because of fever and dysphagia on November 14, 1987. The peripheral leukocyte count was 174,400/microliters with 93% blasts and bone marrow aspiration showed that 90.4% of nucleated cells were blasts positive for both myeloperoxidase and alpha-naphthylbutyrate esterase. Chromosome analysis revealed a karyotype of 45XY, 9q+, 16q+, -20 and 22q-. Esophageal X-ray and endoscopy showed abnormalities. Esophageal biopsy revealed squamous cell carcinoma. He was diagnosed as having Ph1 positive acute myelomonocytic leukemia (AMMoL, M4) and esophageal cancer. He was treated with BHAC-DMP and intermediate-dose ara-C therapy for leukemia and a complete remission was obtained by March 25, 1988. As treatment for esophageal cancer, radiation therapy (total 4,200 cGy) was given and followed by chemotherapy with CDDP and 5-FU. However he died on April 8, 1988. Autopsy findings showed disseminated invasion of esophageal cancer. Ph1 positive AMMoL associated with esophageal cancer is extremely rare.

We asked 2 questions in this study. First was the additional effect of VCR in induction therapy, and the second was the duration of maintenance therapy. Adult AML were treated by an individualized response-oriented induction therapy with behenoyl Ara-C 200 mg/m2 daily + 6MP 70 mg/m2 daily + prednisolone 40 mg/m2 on days 1-4 + DNA 40 mg/m2 on days 1-3 and additionally on days 7, 8, 11, 12 (for M3, DNR 50 mg/m2 daily) (BHAC-DMP) until bone marrow became severely hypoplastic with less than 5% of blasts. Patients were randomized to BHAC-DMP or BHAC-DMP + VCR 0.35 mg/m2 on days 1-4. After obtaining CR, 3 courses of intensive consolidation therapy were given together with I.T. MTX+Ara-C+PSL. Maintenance intensification therapy was randomized to either 4 or 12 courses given every 2 months. Patients of age greater than or equal to 60 received about 2/3 reduced doses. From June 1987 to Sept. 1989, 265 consecutive adult AML were registered from 19 institutions and 258 were evaluable. Age ranged from 15 to 79 (med., 48). Out of 258, 200 (77.5%) achieved CR (80% in 209 of age less than 60 and 65% in 49 of age greater than or equal to 60). Unexpectedly, addition of VCR reduced the high CR rate of BHAC-DMP significantly (84% to 70%, p = 0.007). At the median follow-up of 37 mo., overall survival is 37%, and event-free survival (EVS) 27%. Survival, continuing CR and disease-free survival (DFS) rates of 200 CR cases are 45%, 40% and 35%, respectively. Patients received 12 courses of maintenance therapy showed better DFS (P = 0.0555). The VCR group had significantly worse EFS. By multivariate analysis, significant prognostic factors for the achievement of CR were age less than 60, PS 0-2 and no addition of VCR. Significant factors for longer DFS were induction of CR by one course, FAB M3 or M5 and age less than 50. The present multi-institutional study confirmed the high CR rates of the response-oriented individualized therapy reported from several centers in Japan, but failed to support an additional effect of VCR reported from one center.

Acute leukemia has become a curable disease. In 3 studies for adult AML (BHAC-DMP, BHAC-DMP (II) and M-85) at Nagoya University Hospitals from 1979 to 1987, intensive induction resulted in higher cure rate, and the reduction of the blasts in bone marrow at 2 weeks after the initiation of therapy to less than 20% was the most important prognostic factor to predict the long CR. However, it seemed impractical to give very intensive chemotherapy during the induction because of high frequency of complications due to prolonged myelosuppression. Thus, consolidation should be as intensive as possible. In M-85 protocol, the predicted 5-years survival and disease-free survival (DFS) of CR cases are 70 and 53% respectively. The result of JALSG-AML 87 study seems to confirm the above result. As for the indication of bone marrow transplantation (BMT) at the first CR for adult AML, only a prospective randomized study will answer this important question. In case that DFS of chemotherapy will exceed 40 to 45%, it seems be wise to give chemotherapy first, and then BMT when the leukemia relapse. Differentiation induction therapy seems to be indicated in acute promyelocytic leukemia, although a confirmative study is awaited.

Pulmonary failure is a major contributor to morbidity and mortality during marrow aplasia following high-dose antineoplastic therapy. For this reason, we initiated a pulmonary surveillance program for patients undergoing high-dose chemotherapy for leukemia or bone marrow transplantation. As part of this program, bronchoscopy with BAL was performed prior to therapy and at the onset of granulocytopenia. Thirty-three of the first 57 patients managed in this program developed some evidence of pulmonary complications. Twelve patients died in aplasia; all had pulmonary failure. Forty patients had clinically significant abnormalities on the bronchoscopy before treatment including 12 of 19 patients who had normal findings on chest x-ray films, physical examination, and pulmonary function testing, and no fever. Twenty-seven patients had clinically significant abnormal bronchoscopy or BAL at the onset of granulocytopenia. Thirteen patients required additional bronchoscopy. No patient required an open lung biopsy. Pulmonary surveillance using bronchoscopy with BAL is useful in the detection of pulmonary disease prior to the initiation of and following high-dose antineoplastic therapy.

A 26-year-old male was admitted to our hospital because of fever and leukocytosis. On admission, a white blood cell count was 28,300/microliters with 46.5% blast cells and 16.0% atypical monocytoid cells, a hemoglobin level 13.7 g/dl, and a platelet count 15.0 X 10(4)/microliters. Bone marrow contained 58.8% of peroxidase-negative blast cells. He was diagnosed as acute lymphoblastic leukemia (ALL L2) according to the FAB classification. Chromosome analysis revealed the marrow cells to contain 45, XY, -7, t(9; 22) (q34; q11). On surface marker analysis, the leukemic cells were positive for both lymphoid (CD10) and myeloid markers (CD13). Two color flow-cytometric analysis showed two distinct populations with CD10 and CD1 3, respectively. Rearrangements of both immunoglobulin heavy chain and T cell receptor beta-chain were observed. The "breakpoint cluster region" on chromosome 22 was not rearranged. On the basis of these findings, we thought this case being acute mixed leukemia. He was refractory to AdVP therapy and BHAC-DMP therapy. He is now under treatment with A-Triple-V therapy.

We designed a short term intensive chemotherapy (DCMP-85 regimen) that completed 4 courses of postremission therapy without maintenance therapy in an effort to improve remission durations for adult patients with AML. Twenty six patients aged 14-65 yr were entered into this study. The rate of complete remission is 76.9%. A Kaplan-Meier analysis of patients entering remission predicts that 56% of patients will remain in remission at 3 years (median follow-up is 12 mo). Comparison three different conventional chemotherapies (DC(M)P, DCMP Two Step and BH-AC DMP), DCMP-85 has achieved higher CR rate and 3-year leukemia-free survival rate, so far. Therefore, we conclude short term intensive chemotherapy is getting better results.

A 56-year-old man was admitted to the hospital in April, 1986, with the chief complaint of fatigue. The diagnosis of acute promyelocytic leukemia (APL) was made based on the proliferation of atypical promyelocytes in the bone marrow. No gingival swelling was found on admission. A complete remission was achieved by the BHAC-DMP therapy and maintained by the consolidation therapy and the intensification therapy. In July, 1987, he noticed a solitary gingival tumor around the left lower second molar. The biopsy showed the massive infiltration of leukemic cells, despite the hematological remission. Combination chemotherapy was not effective but the tumor disappeared by irradiation. A hematological relapse occurred in November, 1987, but the second complete remission was achieved by the AB-triple V therapy. He died because of the second hematological relapse in July, 1988. Along with the wide use of intensive chemotherapy for acute leukemia, tumor forming leukemia during the hematological remission, as seen in this case, would be increasing. Thus, we should not overlook any newly formed tumor in the treatment of leukemia.

Between January 1980 and March 1983, a study was conducted on the effects of intensification therapy in 20 adult acute leukemia patients who had achieved complete remission with induction therapy. Intensification therapy consisted of cyclic administration of six combination therapies given at gradually longer intervals, using daunorubicin, cytosine arabinoside, 6-mercaptopurine and prednisolone (DCMP), cyclocytidine (DCyMP), vincristine (DCVP), behenoyl-ara-c (BHAC-DMP), aclacinomycin (BHAC-AMP) and (ACM-MP). Six combinations were given sequentially at one-month intervals, at 2-, 3-, 4-, 5- and eventually 6-month intervals, until 5-year survival. The median remission duration was 38 months for AML, and 17 months for ALL. The median survival was 66 months for AML, and 37 months for ALL. The five year survival rate was 50%. Nine of the 20 patients are still alive. Methotrexate and prednisolone were administered intrathecally for prophylaxis of CNS leukemia on Day 4 for each intensification therapy. There was no CNS leukemia. This intensification protocol was shown to be effective in improving the prognosis of adults acute leukemia.

The acute lymphoblastic cell lines designated BAL-KHc and BAL-KHs were established from the peripheral blood of a Japanese female patient with a B-cell acute lymphoblastic leukemia. The BAL-KHc and BAL-KHs exhibited B-cell characteristics with positive cell markers for CD19, CD20, CD21 and HLA-DR antigens. Immunoglobulin with gamma and kappa chains was demonstrated on the cultured and fresh leukemia cells respectively. The cells lacked the Epstein-Barr virus genome and expressed abnormal chromosome constitutions including a t(8;14)(q24;q32). These results suggested that the cell lines present B-cell characteristics. The BAL-KHc cells showed different cell growth characteristics and cell surface marker profile compared to those of the BAL-KHs. These variations suggest that the BAL-KHc cells were probably frozen at a different stage of B-cell maturation from those of BAL-KHs, although both cell lines originated from the cells in the same peripheral blood sample of the patient.

Between January 1980 and March 1983, a study was conducted into the effects of postremission therapy on 20 patients with acute leukemia who had achieved complete remission through induction therapy. Postremission therapy consisted of cyclic administration of six combination therapies given at gradually longer intervals. Postremission therapy used DCMP (D, daunorubicin; C, cytosine arabinoside; M, 6-mercaptopurine; P, prednisolone), DCyMP (Cy, cyclocytidine), DCVP (V, vincristine), BHAC-DMP (BHAC, behenoyl-ara-c), BHAC-AMP (A, aclarubicin) and ACM-MP (ACM, aclacinomycin). Six combinations were given sequentially starting at one month interval, and then at 2, 3, 4, 5 and eventually 6 month intervals until 5 year survival was reached. The median remission duration was 38 months for acute myelogenous leukemia (AML), and 17 months for acute lymphoblastic leukemia (ALL). The median survival was 66 months for AML, and 33 months for ALL. The survival rate at 5 years was 60% for AML., 40% for ALL, and 50% in all 20 patients. Methotrexate and prednisolone were administered intrathecally for prophylaxis of CNS leukemia on Day 4 of each stage of postremission therapy. There was no CNS leukemia. This postremission therapy was shown to be effective in improving the prognosis of adults with acute leukemia.
