Veno-occlusive disease (VOD) of the liver is characterized by jaundice, painful hepatomegaly, and retention of fluids. VOD is a severe complication in allogeneic stem cell or bone marrow transplantation. Additionally, the disease has been described in children suffering from nephroblastoma or rhabdomyosarcoma, treated with intense chemotherapy. Recently, VOD has been shown to be a complication in the treatment of myeloid leukemia with anti-CD33 linked to calicheamicin. We report the unusual case of a 21-year-old male patient with Marfan syndrome, diagnosed of acute lymphoblastic leukemia, who developed severe VOD during induction therapy after a single application of 2 mg vincristine. We speculate that coincidence of Marfan syndrome and application of induction chemotherapy might favor the disease in our patient.

We studied the histopathological changes of liver in four patients who developed hepatomegaly and abnormal liver chemistry tests 2 to 20 days following administration of L-asparaginase as a part of a combination chemotherapy regimen for treatment of acute lymphoblastic leukemia. The severity of the liver disease due to L-asparaginase was unpredictable. One patient developed acute fulminant hepatic failure and required liver transplantation. The most consistent pathological change, observed in all four cases, was diffuse steatosis. Other changes included patchy hepatocyte necrosis, mixed inflammatory cell infiltrates in the portal tracts, and variable degrees of hepatocellular, or canalicular cholestasis, or a combination of these.

Lymphomas secondarily involving the breast are uncommon, although they do represent the largest group of tumors metastatic to breast. A 20-year-old female with lymphoblastic lymphoma (LBL) presented here with 3 month history of weight loss, night sweats, fatigue and a mass in her left breast. Her physical examination revealed a left breast mass, lympadenopathy, bilateral pleural effusion and hepatomegaly. WBC count was 17,710/mm3 and LDH was mildly elevated. Breast ultrasound showed a 1.7 cm mass in the inner lower quadrant of left breast. Biopsy of the breast mass showed diffuse infiltration with small, round atypical cells which did not stain with CD20, CD43, CD34, cytokeratine and were positive for CD3. She was diagnosed as leukemic phase of a precursor T-cell LBL and treated with 6 cycles of CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone), intrathecal methotrexate and cranial radiotherapy, achieving a complete response. She then was started on maintenance therapy. Four months later she returned with CNS involvement and was started on induction treatment. She had a very aggressive course of disease and died only 12 months after diagnosis. Breast involvement is very rarely seen in precursor T-cell LBL/ALL and in this patient occurred secondarily as part of widespread disease.

A 5-year-old girl developed acute lymphoblastic leukemia (T-ALL) 15 months after being diagnosed with autoimmune hemolytic anemia (AHA), while AHA was in partial remission. AHA was mediated by warm antibodies. Because AHA could not be controlled during the induction therapy of ALL, she was administered immunoglobulin G and plasmapheresis was performed. Hepatomegaly dissappeared in the 4th month. However, anemia requiring blood transfusion, positive direct Coombs' test, and splenomegaly dissappeared in the 13th month of the leukemia treatment; reticulocytosis and decreased haptoglobin level persisted. AHA exacerbated in the 24th month of the ALL therapy. Prednisolone was started but the family refused to continue the therapy. This case presents some features that were not reported before, such that ALL was preceded by AHA and involved T-cell lineage, AHA was mediated by warm antibodies, and the two disorders took place in childhood.

The Children's Cancer Group (CCG) 1952 clinical trial for children with standard-risk acute lymphoblastic leukemia (SR-ALL) compared intrathecal (IT) methotrexate (MTX) with IT triples (ITT) (MTX, cytarabine, and hydrocortisone sodium succinate [HSS]) as presymptomatic central nervous system (CNS) treatment. Following remission induction, 1018 patients were randomized to receive IT MTX and 1009 ITT. Multivariate analysis identified male sex, hepatomegaly, CNS-2 status, and age younger than 2 or older than 6 years as significant predictors of isolated CNS (iCNS) relapse. The 6-year cumulative incidence estimates of iCNS relapse are 3.4% +/- 1.0% for ITT and 5.9% +/- 1.2% for IT MTX; P = .004. Significantly more relapses occurred in bone marrow (BM) and testicles with ITT than IT MTX, particularly among patients with T-cell phenotype or day 14 BM aspirate containing 5% to 25% blasts. Thus, the estimated 6-year event-free survivals (EFS) with ITT or IT MTX are equivalent at 80.7% +/- 1.9% and 82.5% +/- 1.8%, respectively (P = .3). Because the salvage rate after BM relapse is inferior to that after CNS relapse, the 6-year overall survival (OS) for ITT is 90.3% +/- 1.5% versus 94.4% +/- 1.1% for IT MTX (P = .01). It appears that ITT improves presymptomatic CNS treatment but does not improve overall outcome.

Twenty-five children (19 M:6 F) with newly diagnosed ALL with median age of 5.5 years (1 month-12 years) were enrolled in the study. Apoptosis regulator proteins bcl-2 and bax were measured in all patients using alkaline phosphatase anti-alkaline phosphatase method. Twenty-one patients were positive for bcl-2 and 23 cases for Bax, although expression levels varied. Patients who presented with splenomegaly or hepatomegaly < 5 cm expressed significantly higher levels of bcl-2 and bax protein expression. Neither of age ( < or >10 years), sex, generalized lymphadenopathy, WBC ( < or >50,000/mul) or FAB subtype was associated with high levels of bcl-2 or bax protein expression. Patients with higher mean hemoglobin levels (p = 0.009), high blast % in bone marrow (p = 0.02), immature immunophenotype (p = 0.001) exhibited signifxicantly higher bcl-2 levels. Bcl-2/bax ratio correlated inversely with TLC at presentation (p = 0.022; r = - 0.456) and in B-lineage leukemic cells as compared to T-lineage cells (p = 0.002). Bcl-2/bax ratio did not correlate with any other variable measured. Bcl-2 and bax protein co-express in ALL and high bcl-2/bax ratio correlates with good prognosis features.

Immunophenotyping in leukemia offers a precise delineation of the hematopoietic lineage and differentiation stage of the malignant cell. In this study, we used flow cytometry to determine the frequency of the immunologic types of acute lymphoblastic leukemia (ALL) in Moroccan children. We analyzed 100 samples from ALL patients within an age ranging from 6 months to 16 years presented over a 4-year period (1996 to 2000). Immunophenotyping allowed classification into 2 major categories: T-ALL (37%) and B-ALL (63%), with a higher percentage of males (69%). Comparison of the clinical characteristics showed that the frequency of splenomegaly was similar in B-ALL and T-ALL patients (53% and 47%, respectively). Hepatomegaly and mediastinal masses were more often associated with T-ALL (62% and 71%, respectively). Splenomegaly, hepatomegaly, and mediastinal masses were more frequent in immature than mature B-ALL, whereas the reverse was observed for T-ALL. Complete remission was obtained in 88% and 84% of B-ALL and T-ALL, respectively and relapse after 1 year occurred in 30% and 37% of cases, respectively. CD10 expressing B-ALL showed a slightly higher complete remission rate, whereas the reverse was observed for CD10 expressing T-ALL. The overall 5-year survival rate of ALL was 38%, whereas patients with B-ALL showed better survival than children with T-ALL.

Modern intensive chemotherapy regimens have improved the prognosis for adult patients with acute lymphocytic leukemia (ALL). With these regimens, the complete response (CR) rates are approximately 75% and long-term disease-free survival (DFS) rates are about 20-35%. For patients with high-risk ALL, DFS rates are only 20% or less. Hyper-CVAD regimen is effective in ALL and aggressive non-Hodgkin lymphomas (NHL) with increased CR rates and DFS rates. Between June 2002 and October 2006, 53 consecutive adult patients with newly diagnosed adult ALL were treated with Hyper-CVAD regimen for six to eight cycles. The alternating courses were given every 3-4 weeks or earlier if count recovery occurred. CR rates of 73.6% were achieved in 39 patients, the estimated 2-year survival rate was 82.9% and the estimated 2-year event-free survival (EFS) rate was 87.3%. Side effects were as expected, mostly attributed to myelosuppression. Analysis of prognostic factors suggested that some previously well-established poor prognostic factors such as the degree of leukocytosis and central nervous system (CNS) or testicular involvement were less important with this dose-intensive regimen. However, patients with mediastinal disease had lower CR rates (P<0.05), with the presence of hepatomegaly and t(9;22) abnormalities had poor survival (P<0.05). Compared with other established adult ALL regimens, Hyper-CVAD regimen was associated with significantly better CR rates, overall survival and EFS rates. The long-term follow-up results of Hyper-CVAD were favorable.

To evaluate the liver function, splenomegaly and related factors in the newly diagnosed acute leukemia patients. One hundred of fifty eight acute leukemia patients admitted in our hospital from March 2003 to April 2006 were studied. The related factors such as peripheral WBC count, bone marrow blasts, peripheral blasts, sex, age, AML, ALL affecting the liver function and splenomegaly were evaluated. Sixty two (39.24%) patients presented with splenomegaly. Twelve (7.59%) patients presented with hepatomegaly. Serum ALT was elevated in 54 (34.17%) patients. Similarly, serum AST, GGT, ALP, and Direct bilirubin were elevated in 26 (16.45%), 32 (20.25%), 20 (12.65%), and 22 (13.92%) patients, respectively. Low serum albumin was found in 40 (25.31%) patients. PT was prolonged in 62 (39.24%) patients. Statistical study shows that there is a relation between high WBC counts and elevated serum ALT (P<0.05) and high WBC counts and splenomegaly (P<0.05). Acute leukemia patients with leukocytosis are more prone to develop abnormal liver function and splenomegaly.

Treatment of children with acute lymphoblastic leukemia (ALL) is based on P-glycoprotein (P-gp)-dependent cytostatics. We assessed the P-gp function in blast cells as a possible prognostic factor and its influence on the overall survival. P-gp function was measured using the verapamil-sensitive Rhodamine efflux. Cell samples from 7 of 45 (16%) patients revealed rhodamine-efflux positive blasts. There were no relations between the presence of P-gp, clinical characteristics (age, sex, hepatomegaly, and splenomegaly) and initial laboratory parameters (immunophenotype, white blood cells count, and serum lactate dehydrogenase) in ALL. P-gp activity plays a negative role, both for a remission achieved on day 33 and for susceptibility to steroid therapy. Children bearing rhodamine-efflux positive blasts had a significantly shorter 5-year overall survival of 35%, as compared with 74% in those negative for P-gp function. Lack of any association with clinical characteristic and initial laboratory parameters suggests that presence of P-gp is an independent prognostic factor.
