The development of leukemia during pregnancy is rare and difficult to diagnosis and treatment. Acute leukemias are among the most common malignant neoplasms of young women, but paradoxically, their incidence complicating pregnancy is cited to be 0.9 to 1.2 cases per 100,000. l'he signs and symptoms of acut:e leukemia may mask the signs and symptoms of early pregnancy. 'I'he occurrence of acute leukemia during pregnancy raises many therapeut,ic and ethical dilemmas because of the potential tetatogenic effects of chemotherapy and the danger of fetal wastage, in addition to the well-known problem of marrow suppression in the mother. We experienced a case where diagnosis of a woman at the 15 gestational weeks revealed acute lymphocytic leukemia and immediate treatment. as well as termination of pregnancy was made to prevent abnormal neonatal birth. We present this case with review of related literatures.

Between 1986 and 1990, four children with recurrent CNS leukemia who had previous CNS prophylaxis therapy were treated with intermittent central nervous system irradiation and intrathecal chemotherapy (IIIC). There was no isolated CNS recurrence. One patient died form bone marrow relapse. Three patients are alive without evidence of disease for 3E3/12 year to 3E6/12 year after the diagnosis of recurrence of CNS leukemia. This experience suggests that IIIC may be an effective treatment for preventing the recurrence of CNS leukemia without any serious side effects.

We experienced a 22-year old patient with a documented history of minimal change nephrotic syndrome (MCNS), and a diagnosis of acute lymphoblastic leukemia (ALL) was then made for this patient. The patient received standard daily steroid therapy for the treatment of nephrotic syndrome. Cyclosporin A was administered because there was no clinical improvement with steroid therapy. Six years after the diagnosis of nephrotic syndrome, the patient was diagnosed with ALL. After chemotherapy for ALL, the patient was in complete remission and he showed clinical improvement of nephrotic syndrome. The hematological malignancies associated with nephrotic syndrome are mainly lymphoma and chronic lymphocytic leukemia. ALL has rarely been described in combination with nephrotic syndrome. Although the exact mechanism for development of ALL after nephrotic syndrome is unknown, at least two possibilities exist. First, the incidence of leukemia may be increased after immunosuppressive therapy, which may include cyclosporin A. Second, the underlying defect in T-lymphocyte function could account for both nephrotic syndrome and ALL. The possible mechanisms for such a relationship are discussed here along with a review of the relevant literature.

5.Growth Pattern in Children of Acute Lymphoblastic Leukemia during and after Therapy.
Korean Journal of Pediatric Hematology-Oncology 2000;7(1):50-56
PURPOSE: Growth impairment and growth hormone deficiency have been reported in children treated for acute lymphoblastic leukemia (ALL). This study was undertaken to investigate the growth pattern in children who have been diagnosed and treated ALL. METHODS: We have studied growth during 5-year period after diagnosis in 29 children with ALL who achieved complete continuous first remission following induction chemotherapy from January 1991 to December 1998 at Pusan National University Hospital. Maintenance chemotherapy was given over two or three years in all patients and 10 received additional prophylactic cranial irradiation at a total dose 1,800 to 2,000 cGy. RESULTS: Mean age of patients at diagnosis was 5.81+/-3.44 years, mean height standard deviation score (SDS) at diagnosis was 0.58+/-0.78. During 1 st and 2 nd year of therapy, mean height SDS was significantly decreased to 0.21+/-0.78 (P<0.05), 0.26+/-0.99 (P<0.05). And these decreased mean height SDS during therapy were gradually returned to the baseline levels within 2 years after the end of therapy. During and after therapy, there were no significantly differences in changes of mean height SDS between a group who had prophylactic cranial irradiation and one who had not. There were also no significantly different changes of mean height SDS according to sex or age at initiation of treatment. CONCLUSION: Our data indicate that chemotherapy significantly affects growth of patients treated for ALL and that effects were almost transitory, whereas radiotherapy at the doses used in this study does not potentiate growth impairment.

PURPOSE: To assess the importance of early clearance of blast cells in peripheral blood and the predictability of outcome in childhood acute lymphoblastic leukemia (ALL) through this method. METHODS: We reviewed medical records of all childhood patients with ALL enrolled on Severance Hospital (January 1992 to December 1997) to determine the presence of blast cells in peripheral blood at diagnosis and after 1 week of intensive induction therapy. RESULTS: Persistent circulating leukemic blasts were present at day 7 in 14 patients (11.4%) among 123 ALL patients. Compared with blast negative group, these patients had two adverse clinical and laboratory features (Hemoglobin level and L2 morphology), and a poorer 4-year event-free survival (69.8% vs. 82.7%, P<0.01). CONCLUSION: We found that this simple and noninvasive method, which can replace bone marrow examination, may be very beneficial to predict the prognosis of ALL.

BACKGROUND: Lymphocytes seen during the chemotherapy of childhood ALL are not fully understood regarding their clinical significance. The lymphoid aggregates found during the complete remission period are more confusing. We investigated the characteristics of lymphoid aggregates and the clinial course of children with these in the marrow during the chemotherapy of childhood ALL. This is the first study about this subject. METHODS: From January 1996 to April 1998, 210 bone marrow specimens were diagnosed as complete remission status of ALL and among them, ten patients (4.8%) showed lymphoid aggreagates on the marrow clot sections at the time of complete remission. We reviewed bone marrow specimens, performed immunohistochemical stains for CD3, CD 10 and CD79a and investigated the clinical course. RESULTS: The ten cases were composed of nine ALL, L1 and one ALL, L2. All of them were treated under guidance of the CCG (children's cancer group) protocol. Fourteen lymphoid aggregates from ten cases were found. They showed mean number of 1.4 per clot section, mean diameter of 132 micrometer, regular (36%) or irregular (64%) margin and composition of mature lymphocytes (21%), immature lymphocytes (29%) or mixed pattern (50%). The mean interval between the diagnosis and the emergence of lymphoid agregates was 29 months (2~55 months). One patient in the course of consolidation chemotherapy expired due to upper gastrointestinal bleeding and other nine cases are still in the continuous complete remission state. The lymphoid cells consisting of lymphoid aggregates showed positive reaction only for CD79a and negative reactions for CD3 and CD10. CONCLUSION: Lymphpoid aggregates found at the time of complete remission are collections of regenerating B-lymphocytes and they are not residual leukemic blasts, and show no effect on the complete remission state.

BACKGROUND: Precursor T-cell acute lymphoblastic leukemia (T-ALL) has worse prognosis than B-cell ALL. We aimed to evaluate prognostic variables in pediatric T-ALL. METHODS: Medical records of 36 T-ALL patients (27 males and 9 females; median age at diagnosis, 10.6 years) diagnosed and treated at Asan Medical Center from 2001 to 2017 were reviewed. Six patients (16.7%) had early T-cell precursor ALL (ETP-ALL). Most patients received the Children's Cancer Group-1882 (CCG1882) or Korean multicenter high risk ALL (ALL0601) protocols and prophylactic cranial irradiation. Clinical features at presentation, response to therapy, and treatment outcomes were analyzed. RESULTS: The six patients with ETP-ALL and 17 of 30 with non-ETP-ALL received CCG1882 or ALL0601 chemotherapy. Three patients, including two with ETP-ALL, did not achieve complete remission after induction. Rapid early response during induction was achieved by 26 patients. Five year overall survival (OS) and event free survival (EFS) rates were 71.4% and 70.2%, respectively. ETP-ALL and slow early response during induction were significant adverse prognostic factors, while hyperleukocytosis at diagnosis was not. CCG1882/ALL0601 chemotherapy resulted in superior survival (OS: 78.9%, EFS: 73.3%) compared with CCG1901 chemotherapy (OS: 64.3%, EFS: 64.3%), and patients undergoing prophylactic cranial irradiation had superior EFS to non-radiated patients. CONCLUSION: A high risk ALL protocol with intensified post-remission therapy, including prophylactic cranial irradiation, conferred T-ALL survival outcomes comparable with those of Western studies. Further treatment intensification should be considered for patients with ETP-ALL and slow induction responders. Additionally, CNS-directed treatment intensification, without prophylactic cranial irradiation, is needed.

OBJECTIVE:
To explore the consistency of flow cytometry (FCM) method and polymerase chain reaction (PCR) technique in the detection of minimal residual disease (MRD) at different treatment stages in pediatric patients with TCF3/PBX1+ B-cell acute lymphoblastic leukemia (B-ALL) and the correlations between the detection results and prognosis.
METHODS:
The clinical data of 64 newly diagnosed pediatric patients with TCF3/PBX1+ B-ALL admitted to the Department of Pediatrics of Peking University People's Hospital from January 2005 to December 2017 were retrospectively analyzed. FCM and PCR methods were used to monitor the MRD level in bone marrow samples from 64 children during the same period of treatment on d33 and d90 respectively, and the detection results were analyzed.
RESULTS:
There were 37 males and 27 females in the 64 patients, with a median age of 8 years(range 0.8 to 16 years). The complete remission (CR) rate after the first cycle of induction chemotherapy was 98.4% (62/63), with overall CR rate of 100%. 12 patients experienced recurrence, with a median recurrence time of 16.9 (5.3-46.3) months. The median follow-up time of the 64 patients was 77.2 (1.0-184.8) months , and the 5-year overall survival (OS) rate and event-free survival (EFS) rate were 82.8%±4.7% and 75.0%±5.4%, respectively. On d90, the concordance rate of the MRD results from the two methods was 98.4%, and the related kappa value was 0.792 (P < 0.001), which were significantly higher than those on d33. After induction chemotherapy (d33), the 5-year EFS rate of MRD-FCM- group (79.3%±5.3%) was significantly better than that of MRD-FCM+ group (40.0%±21.9%) (P =0.028), there were no significant differences in the 5-year OS rate and EFS rate between MRD-PCR+ group and MRD-PCR- group, and the 5-year EFS rate of MRD-FCM-/PCR- group (85.4%±5.5%) was significantly better than that of MRD-FCM+/PCR+ group (40.0 %±21.9%) (P =0.026).
CONCLUSION
In children with TCF3/PBX1+ B-ALL, the MRD results detected by FCM and PCR methods show good consistency, especially in consolidation therapy period (d90). The MRD level at the end of induction therapy (d33) is an important factor affecting the long-term prognosis, especially the MRD results detected by FCM method, which is significantly associated with prognosis.

A 15-year-old patient, who had been diagnosed and treated as Burkitt cell type acute lymphoblastic leukemia (ALLL3) already, visited our department. He complained of gingival enlargement and loosening teeth 1 month ago. The clinical examination revealed anterior open bite, gingival enlargement, and nontender swelling particularly in molar regions of both jaws. Deep periodontal pockets and severe mobility was shown on most of the teeth. The panoramic radiographs showed severe bone destruction and extrusion of the molars. The contrast enhanced CT showed multiple enhanced mass and bone marrow obliteration in both jaws. Chemotherapy was done and the swelling was subsided at 1 month later. In conclusion, radiologic findings of leukemia with soft tissue mass, known as chloroma or granulocytic sarcoma, mimic those of lymphoma, so blood test may be needed for the final diagnosis.
