ABSTRACT
OBJECTIVES: It is well known that Acute Leukemic patients with Hyperleukocytosis (ALH, leukocyte count>or=100,000/micro L) have poor prognosis. This is indebted in fatal complications arising from cerebral and pulmonary leukostasis. To investigate the factors influence on the prognosis of these patients, we have analyzed age, sex, laboratory findings and complications and their relationship to remission rate. METHODS: Retrospective evaluation was done from January 1985 to March 1994 on fifty-four patients with ALH. We excluded secondary leukemias transformed from chronic myelogeneous leukemia, relapsed acute leukemia and myelodysplastic syndrome in this study. The prognostic factors associated with early death were also evaluated. RESULTS: 1) Hyperuricemia and incidence of central nervous system and respiratory symptoms were higher in acute myelogeneous leukemia (AML) with hyperleu-kocytosis than in acute lymphocytic leukemia (ALL), 2) Twenty-two of fifty-four patients had complete remission by remission induction chemotherapy. Remission rate was 41%, median duration of remission was 26 weeks and 1 year survival rate was 11%. 3) There were no differences in remission rate between male and female and higher WBC group (WBC>or=200,000/micro L) and lower WBC group (WBC 100,000~200,000/micro L). 4) The group with better performance status (ECOG score1-2), younger (age below 40) and higher hemoglobin level (Hb>or=10g/dL) had higher remission rate. The group of AML and with hepatomegaly had lower remission rate than the group of ALL and without hepatomegly. 5) Early death rate of AML was higher than that of All. Infection was the most common cause of early death in both AML and ALL. 6) Early death rate between the two groups managed with and without leukapheresis was not different. CONCLUSIONS: This result reveals that acute leukemia with hyperleukocytosis is grave disease, especially the patients with poor performance status (ECOG score: 3-4), older age above 40 and severe anemia (Hb<10g/dL) have poor prognosis, The group of AML and with hepatomegaly showed worse prognosis than the group of ALL and without hepatomegaly.

Primary lymphoma of the central nervous system is a rare disease, occurring spontaneously and/or in conjunction with immunosuppressive state. Its incidence is increasing according to the increment of organ transplantation and AIDS. Recently we experienced a case of primary lymphoma occurred in central nervous system after renal transplantation in a 58-year-old women who had complained of persistent headache and left hemiparesis. CT scan of the brain showed two hyperdense mass lesions in right frontal and right basal ganglia areas. Immunohistochemical stain of the excised mass lesion revealed that tumor cells were derived from B cells. The patient was treated with discontinuance of immunosuppressive drug and irradiation, but expired due to pneumonia.

OBJECT: Peripheral blood stem cells(PBSC) were collected after remission induction chemotherapy and reinfused after intensified chemotherapy in order to increase the chemotherapeutic efficacy. METHOD: Collection of mononuclear cells(MNC) was started when CD34+ cells above 1% and WBC above 1,000/ul with mononuclear cell percentage above 30%, the collection procedures were done 2-6 times in each patient of total 6 cases. The collected MNCs were stored in -75 degrees C and reinfused after thawing in the water bath at 37 degrees C. RESULTS: Twenty three collection procedures from the 6 cases of acute leukemia had made effective MNC collection in 4 cases and mean collection efficiency was 49.8%(from 39.0% to 74.5%). Hematological changes after the procedure were mean reduction of hemoglobin 1.34g/dl and mean 20.25% of decreased platelet count. There were noticed transient symptoms of discomfort, coughing, chest tightness and dyspnea in association with the infusion of stored cells. CONCLUSION: The basic process for the peripheral blood stem cell transplantation(PBSCT) was accomplished with this supportive care for the consolidation chemotherapy of acute leukemia. Effective PBSCT would be warrented with more qualified process and high dose chemotherapy.
