    ABSTRACT: The reported long-term outcome of endemic Burkitt lymphoma (eBL) patients who present with paraplegia is largely unknown. Records of BL patients treated with comparable short-interval cyclophosphamide chemotherapy schedules between 2004 and 2014 at three Baptist mission hospitals in Cameroon were reviewed. Survivors were followed up and examined at home or in hospital. Eighty-seven of 948 (9.2%) patients had paraplegia at diagnosis. The survival rate in eBL patients with paraplegia at diagnosis was 33% (n = 29) after follow-up of between 2 and 96 (median 40) months. Seven patients (24%) had neurological sequelae and needed rehabilitation. There was no relationship between the duration of symptoms (<2, 2-4, >4 weeks) and the survival rate or the risk to have neurological sequelae. The survival rate and risk for sequelae were similar in patients with confirmed St. Jude stage III and IV diseases.

    ABSTRACT: This review aims to summarize the evidence for impairments of muscle strength and balance during and after treatment for childhood cancer. Thirty-two articles, identified in scientific databases by means of a structured search for investigations of muscle strength and balance in pediatric cancer patients and survivors, are evaluated. A summary of results is given with respect to matching reporting items to provide a qualitative analysis of the evidence. The majority of the studies reached a level 3 rating according to Oxford Centre for Evidence-Based Medicine (OCEBM) 2011 levels of evidence. Muscle strength and balance seem to be impaired in varying degrees depending on the diagnosis, treatment received, and time elapsed between treatment and evaluation. Drawing specific conclusions from the identified studies is difficult because of heterogeneous study samples and methods of research. Individual targeted exercise therapy programs during treatment and follow-up of childhood cancer could help to prevent and further diminish impairments of muscle strength and balance function among childhood cancer patients and survivors.

    ABSTRACT: Facilities for measuring methotrexate (MTX) levels are not available everywhere, potentially limiting administration of high-dose methotrexate (HDMTX). We hypothesized that serum creatinine alteration after HDMTX administration predicts MTX clearance. Overall, 122 cycles in 50 patients of non-Hodgkin lymphoma or acute lymphoblastic leukemia aged ≤18 years receiving HDMTX were enrolled prospectively. Plasma MTX levels were measured at 12, 24, 36, 48, 60, and 72 hours; serum creatinine was measured at baseline, 24, 48, and 72 hours. Correlation of plasma MTX levels with creatinine levels and changes in creatinine from baseline (Δ creatinine) were evaluated. Plasma MTX levels at 72 hours showed positive correlation with serum creatinine at 48 hours (P = .011) and 72 hours (P = .013) as also Δ creatinine at 48 hours (P = .042) and 72 hours (P = .045). However, cut-off value of either creatinine or Δ creatinine could not be established to reliably predict delayed MTX clearance. Greater than 50% Δ creatinine at 48 and 72 hours significantly predicted grade 3/4 leucopenia (P = .036 and P = .001, respectively) and thrombocytopenia (P = .012 and P = .009, respectively) but not mucositis (P = .827 and P = .910, respectively). Delayed MTX elimination did not predict any grade 3/4 toxicity. In spite of demonstration of significant correlation between serum creatinine and Δ creatinine with plasma MTX levels at 72 hours, cut-off value of either variable to predict MTX delay could not be established. Thus, either of these cannot be used as a surrogate for plasma MTX estimation. Interestingly, Δ creatinine effectively predicted hematological toxicities, which were not predicted by delayed MTX clearance.

    ABSTRACT: Voriconazole is an antifungal drug used to treat fungal infections. This was a retrospective study of 61 children with hemato-oncologic diseases or solid organ transplantation who were administered voriconazole for invasive fungal infections. Of the 61 patients, 31 (50.8%) were in the therapeutic drug monitoring (TDM) group, and 30 (49.2%) were in the non-TDM group. At 12 weeks, treatment failure rate in the non-TDM group was higher than the TDM group (78.6% versus 40.0%, p = 0.038). Drug discontinuation due to adverse events was less frequent in the TDM group than the non-TDM group (26.0% versus 92.3%, p = 0.001). Children required higher dosages to maintain drug levels within the targeted therapeutic range: an average of 8.3 mg/kg/dose in patients <12 years old and 6.9 mg/kg/dose for those ≥12 years old. Treatment failure rates were higher in patients whose voriconazole levels remained below 1.0 mg/L for more than 50% of their treatment duration than those above 1.0 mg/L (71.4% vs. 9.1% after 12 weeks, p = 0.013). Serial monitoring of voriconazole levels in children is important for improving treatment response and preventing unnecessary drug discontinuation. Higher dosages are needed in children to reach therapeutic range.

    ABSTRACT: To systematically review and meta-analyze the outcome of Hodgkin lymphoma patients with a posttreatment (18)F-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET)-negative residual mass. A systematic PubMed/MEDLINE database search was performed. The methodological quality of included studies was assessed. The number of patients with a posttreatment non-FDG-avid residual mass and the number of these patients who developed disease relapse during follow-up were extracted from each included study. Heterogeneity in disease relapse proportions across individual studies was assessed using the I(2) test, with heterogeneity defined as I(2) > 50%. Using a Freeman-Tukey transformation, the disease relapse proportions from each individual study were then meta-analyzed with either a fixed-effects model (if I(2) ≤ 50 %) or a random-effects model (if I(2) > 50 %). A total of 5 studies comprising a total of 727 Hodgkin lymphoma patients with an FDG-PET-negative residual mass after first-line therapy were included. The overall quality of included studies was moderate. The proportion of patients with a posttreatment non-FDG-avid residual mass who experienced disease relapse during follow-up ranged between 0% and 13.8%. There was heterogeneity in disease relapse proportions across individual studies (I(2) = 61.4%). Pooled disease relapse proportion (random effects) was 6.8% (95% confidence interval: 2.6%-12.5%). The disease relapse rate in Hodgkin lymphoma patients with a FDG-PET-negative residual mass after first-line therapy is approximately 6.8%. Considering the existing literature, the presence of a non-FDG-avid residual mass has not been proven yet to be associated with a worse outcome than a posttreatment FDG-PET-based complete remission status without a residual mass.

    ABSTRACT: The incidence of acute invasive fungal rhinosinusitis (AIFR) is rising due to more aggressive chemotherapy and longer survival of immunosuppressed patients. Early diagnosis and appropriate but nonmutilating surgical treatment are particularly problematic in the pediatric population. This study aimed to evaluate the outcome of surgery for pediatric AIFR. Medical records of children surgically treated for AIFR between 1998 and 2014 were reviewed. Diagnosis was based on both histopathological and microbiological confirmation. Surgery was performed with curative intent and repeated for any resectable extension. The children underwent endoscopy and magnetic resonance imaging every 2 and 6 months, respectively, during the first postoperative year. Thirteen patients (2-18 years old) met the EORTC/MSG criteria for proven invasive fungal sinusitis; fungal invasion was diagnosed by preoperative biopsy and confirmed in the surgical specimen. All patients underwent an average of two endoscopic procedures (range 1-3), and four of them also underwent an open surgery. The local control rate was at least 79%. There was no facial disfiguration during follow-up (average 41 months). Although AIFR is still associated with high mortality, aggressive medical and surgical treatment provides local control in most cases. Fair outcome should encourage a maximal joint effort of pediatric hemato-oncologists and otorhinolaryngologists in the management of AIFR.

    ABSTRACT: MYC and BCL2 translocations in B-cell lymphomas are defined as "double-hit" associated with poor prognosis in adult patients. Such double-hit events are extremely rare in B-cell precursor acute lymphoblastic leukemia (BCP-ALL), especially in pediatric patients or young adults. This study is to investigate the clinical manifestation of de novo MYCyBCL2 double-hit BCP-ALL in young patients. Two pediatric and one young adult patients were identified after a retrospective data review and all without previous history of lymphoma. There were two females and one male aged 15, 18, and 24, respectively. All patients had an unremarkable medical history before presenting with extensive bone marrow and central nervous system involvement at diagnosis. Flow cytometry immunophenotypic analysis showed an immature B-cell immunophenotype (CD10+, CD19+, TdT+, surface Ig-) and immunohistochemistry showed high expression of MYC and BCL2 in all cases. All patients showed complex karyotypes associated with 8q24 abnormalities in the form of t(8;9)(q24;p13) or t(8;14)(q24;q32) and t(14;18)(q32;q21) and fluorescence in situ hybridization confirmed MYC and BCL2 rearrangements. Two patients died of refractory disease or disease progression 7 and 13 months after initial diagnosis, respectively, and the third patient was treated with protocol AALL0232 under the Children's Oncology Group study, achieved complete remission and remained in remission for 53 months at last follow-up. Our study showed that De novo MYCyBCL2 double-hit BCP-ALL is a rare disease that also occurs in pediatric and young adult patients and associated with complex karyotypes and poor prognosis. Younger patients may benefit from intensified chemotherapy.

    ABSTRACT: According to the Fifth National Wilms Tumor Study (NWTS-5), tumor-specific loss of heterozygosity (LOH) for chromosomes 1p and 16q identifies a subset of patients with Wilms tumor (WT) who despite having favorable histology (FH) have a significantly increased risk of relapse and death. We aimed to find out 1p and 16q LOH frequencies in patients with FH-WT as well as its correlation to survival outcome and epidemiologic and clinical characteristics. Data of patients with FH-WT presenting to the National Cancer Institute, Egypt, were retrospectively analyzed. Paraffin blocks were tested for 1p and 16q LOH using polymorphic loci that span the minimal regions of LOH at this area. The study included 100 patients with a median age of 5 years. Thirty-nine patients (39%) showed LOH at 1p (n = 14), 16q (n = 13), or both (n = 12). LOH was most frequently encountered in patients above 10 years (5/5), advanced stages disease (80% of stage V and 50% of stages IV and III each). The 3-year overall survival (OS) and event-free survival (EFS) were significantly lower in patients with double LOH (75% and 50%, respectively), followed by 16q (92% and 54%), in comparison with 1p (93% each) and negative LOH (97% and 100%) cases, respectively (p = 0.001). Combined LOH (1p+16q), followed by 16q LOH alone, was predictive of poorer outcome and was associated with lower OS and EFS in patients with FH-WT. Our results showed a higher-risk disease that would suggest the need for an intensified upfront therapy in this group of patients.

    ABSTRACT: The presence of lupus anticoagulants (LAs) is an important cause of activated partial thromboplastin time (aPTT) prolongation found in children after an infection or during screening tests before surgical intervention. The authors retrospectively reviewed the charts of 68 patients who have been consulted from surgery departments with prolonged aPTT. These patients were reevaluated with aPTT analysis after 1 week. Thirteen patients had normal aPTTs. Therefore, 55 patients remained with prolonged aPTTs. LA positivity was detected in 39 patients. Sixteen of these had prolonged aPTT prior to surgery (41%). Others with LA positivity had systemic lupus erythematosus (SLE; n = 6), infection (n = 5), leukemia (n = 3), hemolytic uremic syndrome (n = 2), epistaxis (n = 2), antiphospholipid syndrome (APS; n = 1), chronic immune thrombocytopenic purpura (n = 1), acute poststreptococcal glomerulonephritis (n = 1), central nervous system (CNS) thrombosis (n = 1), and congenital heart disease (n = 1). None of the patients had bleeding history. LA positivity rarely leads to bleeding and/or thrombosis. Specific therapy is usually not needed. Further prospective multicenter studies are required to understand clinical outcomes and laboratory correlation in children with positive LA.

    ABSTRACT: We describe a child with a 2-week history of progressive headaches, blurry vision, and intermittent vomiting. Magnetic resonance imaging (MRI) of the brain showed a deep left hemispheric lesion with extension into the corpus callosum. Histology and immunophenotyping of the lesion was consistent with peripheral T-cell lymphoma, not otherwise specified. Chemotherapy was initiated and a complete remission was achieved. This case illustrates that a chemotherapeutic regimen used in adults with central nervous system (CNS) lymphoma can achieve durable remissions in pediatric patients with peripheral T-cell lymphoma, not otherwise specified of the CNS.

    ABSTRACT: In this study, we aimed to determine serum adrenomedullin levels and compare them with levels of C-reactive protein (CRP) and procalcitonin (PCT). Cancer patients aged 0-18 years who experienced febrile neutropenia attacks were included in the study. Adrenomedullin, CRP, and PCT were analyzed at admission, day 3, and days 7-10 later. Fifty episodes of febrile neutropenia that developed in 37 patients were analyzed in this study. The mean age of the patients was 7.5 ± 4.7 (1-18) years. The patients had leukemia (73%), solid tumors (19%), and lymphoma (8%). The percentages of the patients in the clinically documented infection (CDI), fever of unknown origin (FUO), sepsis, and microbiological documented infection (MDI) categories were 34%, 34%, 20%, and 12%, respectively. During the study period, four patients were lost. In the MDI group, adrenomedullin levels on day 3 were significantly higher than those in the CDI and FUO groups. PCT levels were significantly higher in the sepsis group than those in the CDI group at admission, day 3, and days 7-10. In the sepsis group, PCT levels on days 7-10 days were significantly higher than those in the sepsis group. PCT values from the deceased patients on days 7-10 were significantly higher than those from patients who survived. CRP levels did not differ significantly among the febrile neutropenia groups. First, in our study, adrenomedullin was used as a biomarker in the febrile neutropenia episodes of children with cancer. Among adrenomedullin, CRP, and PCT, procalcitonin demonstrates the highest correlation with the severity of infection.

    ABSTRACT: Breastfeeding is well-known to have a protective effect against infection in infants. It has been suggested that breast milk may play a role in the prevention of certain childhood cancer. We investigated this issue in a case-control study comprising 300 patients with childhood cancer. There was 73 patients (24.3%) with leukemia, 82 patients (27.3%) with lymphoma, and 146 patients (48.4%) with solid tumors (brain tumors, neuroblastoma, soft tissue sarcomas, germ cell tumors, renal tumor, bone tumor, retinoblastoma, hepatoblastoma, and others) and 316 controls matched for age and sex. Breastfeeding duration of the control group was found to be significantly longer than the patient group (X2 = 57.774; P < .001). In conclusion, breastfeeding was found to be inversely associated with pediatric cancer in our study.

    ABSTRACT: Background: Acute lymphoblastic leukemia (ALL) is the most common cancer in children and L-asparaginase is an essential component of the treatment. Cessation of L-asparaginase decreases event free survival. Acute pancreatitis is the toxicity that most commonly results in cessation of L-asparaginase. We tested whether serial ultrasound examinations could predict asparaginase-associated pancreatitis (AAP). Methods: Children (aged 1.0-17.9 years) with childhood ALL treated at the University Hospital Rigshopitalet, Copenhagen, according to the standard or intermediate risk arms of the NOPHO ALL2008 protocol, with PEG-asparaginase of 2 or 6 week intervals, for 30 weeks had their pancreas monitored using serial ultrasound in order to detect early signs of inflammation. Results: Nineteen of 31 eligible patients were included. Three of the included patients developed AAP. None of the patients, including the three patients that developed AAP, had signs of inflammatory edema or pancreas enzymes above three times the upper normal limit prior to AAP. Conclusion: We found no signs of inflammatory edema within the pancreas on ultrasound during treatment with PEG-asparginase in our cohort prior to development of AAP or in patients that did not develop AAP.

    ABSTRACT: Due to the poor survival in high-grade glioma (HGG), secondary solid malignancies (SSM) following pediatric HGG are scarce. The authors present the experience from the HIT-HGG database in Germany, Austria, and Switzerland. Five out of 1228 pediatric HGG patients developed a SSM following a latency of 29-122 months from primary HGG diagnosis. In 4 patients, the SSM may be attributed to previous radiotherapy or a tumor predisposition syndrome, reflected by a markedly increased cumulative incidence rate of SSM in patients with tumor predisposition. Survival was devastating, since none of the patients survived beyond 18 months from SSM diagnosis.

    ABSTRACT: Children are at greater risk for malnutrition due to increased needs of nutrients to obtain appropriate growth, and they exhibit elevated substrate needs due to cancer and its treatment. This study aimed to report anthropometric and biochemical evaluation of nutritional status in children with cancer at initial presentation and during treatment. A prospective, controlled study was performed in the pediatric oncology department of a tertiary care center. Control group consisted of the siblings of patients. Weight, height, body mass index, triceps skinfold thickness, and serum levels of total protein, albumin, prealbumin, serum lipids, trace minerals, C-reactive protein (CRP), and vitamins were compared in patients and controls at initial presentation and at 6th month after the onset of treatment. According to weight for height, the frequency of malnutrition was 16% at initial presentation and 22% at 6th month. Triceps skinfold thickness was significantly thinner in patients than controls at both measurements. Patients had lower levels of prealbumin, albumin, iron, folate, zinc, and vitamin C and higher levels of ferritin, vitamin B12, and copper. Serum CRP levels were significantly higher in cancer patients at initial presentation and seemed to be correlated with copper levels. Compared with other patients, malnourished patients had significantly higher levels of vitamin B12 at 6th month. Results of the current study demonstrate that trace minerals, vitamins, and anthropometric measures may yield important clues for nutritional status and disease activity in pediatric oncology patients. However, validation and updating these potential markers warrant further trials on larger series.
