Osteonecrosis is a debilitating toxicity associated with acute lymphoblastic leukemia (ALL) treatment. A recent report associated interindividual differences in hip anatomy with the development of idiopathic osteonecrosis in adults. To evaluate the impact of hip anatomy on the development of therapy‐related osteonecrosis, we retrospectively evaluated the femoral neck‐shaft angle, femoral neck offset, and lateral center‐edge angle using x‐rays of 18 osteonecrosis cases and 46 control children treated for newly diagnosed ALL on a single protocol. Despite adequate statistical power, we found no association between hip anatomy and osteonecrosis. Investigation of other factors contributing to ALL‐associated osteonecrosis is warranted. 相似文献

With current treatments for acute lymphoblastic leukemia (ALL), the overall prognosis for survival is favorable. Increasing emphasis is placed on recognizing and managing the long‐term consequences of ALL and its treatment, particularly involving osteonecrosis. Early osteonecrosis diagnosis and management may improve outcomes and is best accomplished through coordinated teams that may include hematologic oncologists, radiologists, orthopedic surgeons, physical therapists, and the patient and their family. Magnetic resonance imaging is the “gold standard” for diagnosis of early‐stage and/or multifocal osteonecrosis. Treatments for osteonecrosis in ALL patients are risk stratified and may include observation, corticosteroid or chemotherapy adjustment, and pharmaceutical or surgical approaches. 相似文献

Brain abscesses in children with leukemia or other malignancies are rare and potentially fatal. We report on four children who developed brain abscesses during treatment for acute lymphoblastic leukemia (ALL). All patients received multimodal broad-spectrum antibiotic therapy and liposomal amphotericin-B in combination with hyperbaric oxygen. First-line antimicrobial treatment was modified when a causative organism was isolated. All four patients survived, with two patients showing complete resolution of neurological and MRI abnormalities and with two patients still having residual lesions. To date, all patients are in remission with three patients still receiving antileukemic therapy. Brain abscesses can be successfully managed by a multimodality approach even in severely immunocompromised cancer patients. 相似文献

BACKGROUND: Growth deficit has been reported as a frequent complication of the treatment of acute lymphoblastic leukemia (ALL). PROCEDURE: Longitudinal analysis of the growth of 129 children, from a total of 351 cases diagnosed between 1987 and 1994 in Brazil, was determined. Height data were converted into standard deviation Z scores. Only girls younger than 10 and boys younger than 12 years old at diagnosis were included. Patients were treated according to a German BFM-83 based protocol. Fifty-eight children received 18 Gy cranial irradiation, four 12 Gy, and two 24 Gy. Patients were aggregated into five non-excluding groups according to availability of height data at diagnosis, during the treatment, at the end of it, and several years after; 35 children reached their final height. RESULTS: Height deficit at the end of the therapeutic treatment was evident (P < 0.0001). Catch-up occurred 1 year after stopping treatment (P = 0.016). At the last follow-up, over 5 years after the end of treatment (n = 83) or at final height (n = 35), impressive height deficits were recorded (P < 0.0001 for both end points). Multivariate analysis demonstrated that growth impairment was more severe in children younger than 4 years at diagnosis and in those who received cranial irradiation. No significant effect of gender was observed. Children who were treated solely with chemotherapy also had significant height loss. CONCLUSIONS: Treatment of ALL in children is associated with growth deficit during the treatment and several years after it, affecting the final height negatively, particularly in patients younger than 4 and in those who received cranial irradiation. 相似文献

Hypersensitivity to pegaspargase is associated with inferior survival in pediatric patients with acute lymphoblastic leukemia and lymphoblastic lymphoma. In the past year, drug‐supply shortages have led to the lack of an available alternative to pegaspargase. Rather than omit asparaginase from the treatment of acute lymphoblastic leukemia or lymphoblastic lymphoma patients with hypersensitivity to pegaspargase, we continued pegaspargase treatments for nine pediatric patients, utilizing a rapid desensitization protocol. There were no adverse events related to the pegaspargase during desensitization, and all patients who were checked had asparaginase serum levels above the threshold of 0.1 IU/mL at 7 to 14 days after pegaspargase therapy. 相似文献

Background
Most children with cancer live in developing countries where the prevalence of malnutrition may reach 50% and influence the course of the disease. This study examined the prevalence and severity of malnutrition at diagnosis, as well as after 3 and 6 months of chemotherapy, in children with acute lymphoblastic leukemia (ALL) in Guatemala.Methods
Triceps skin fold thickness (TSFT) and mid upper arm circumference (MUAC) provided measures of nutritional status (NS) in three categories: adequately nourished (A): TSFT and MUAC > 10th percentile; severely depleted (SD): TSFT or MUAC < 5th percentile; and moderately depleted (MD): all the remaining patients.Results
Of 331 new patients, 241 had NS assessed at diagnosis. A = 113 (46.9%); MD = 28 (11.6%); SD = 100 (41.5%). At 3 months A = 106 (52.2%); MD = 25 (12.3%); SD = 72 (35.5%). At 6 months A = 146 (76.0%); MD = 12 (6.3%); SD = 34 (17.7%). In multivariate analysis, SD children at 6 months of treatment had a hazard of death that was 2.4‐fold the hazard of those A or MD (95% CI: 1.3–4.7)Conclusions
Malnutrition is prevalent in newly diagnosed children with ALL in Guatemala and severe nutritional depletion is apparently predictive of abandonment of therapy and relapse of disease, but if children survive and improve their NS in the first 6 months after diagnosis, their chances of survival may improve significantly to approximate those in children not presenting with nutritional depletion.

BACKGROUND: Transient hyperglycemia occurs commonly during the treatment for childhood acute lymphoblastic leukemia (ALL). The purpose of this study was to examine the incidence of and risk factors for transient hyperglycemia during induction chemotherapy in Hispanic pediatric patients diagnosed with B-Precursor ALL. PROCEDURE: The study cohort consisted of 155 Hispanic pediatric patients diagnosed with ALL and treated at one of two South Texas pediatric oncology centers between 1993 and 2002. Hyperglycemia was defined as > or = 2 glucose determinations of > or = 200 mg/dl during the first 28 days of induction chemotherapy. RESULTS: Overall, 11.0% of the study cohort developed transient hyperglycemia during induction chemotherapy. Age and body mass index (BMI) were both positively associated with the risk of hyperglycemia. Females exhibited a substantially higher risk of hyperglycemia than males, but this association did not reach statistical significance after adjusting for other covariates. Among patients who developed hyperglycemia, 100% of those who required insulin were in the 13-18-year age group and reported a family history of diabetes. Hyperglycemic patients classified as obese (BMI > or = 95 centile) were more than twice as likely to have required insulin therapy compared to overweight patients (BMI 85-<95 centile) and three times as likely to have required insulin compared to normal weight (BMI < 85 centile) patients. CONCLUSIONS: The incidence of chemotherapy-induced transient hyperglycemia in the present study cohort is comparable to that reported in previous pediatric ALL patients. This finding is interesting in view of the elevated prevalence of obesity and the underlying dietary behaviors in this Hispanic study cohort. 相似文献

Some cases of conversion from acute lymphoblastic leukemia (ALL) to acute nonlymphoblastic leukemia (ANLL) at relapse have been reported recently. We report three cases initially diagnosed as having ALL and showing morphological, cytochemical, and immunophenotypic features of ANLL at relapse (lineage switch). Conversion was observed among 14 patients who developed bone marrow relapse while undergoing intensive treatment with our ALL protocol, which includes teniposide, and that had been administered to 62 patients. The three cases converted at first relapse, with a mean time of 20 months (13–29 months). Clinical and immunologic characteristics of T-cell leukemia were present in one patient. Changes documented in cytogenetic studies are discussed. The underlying mechanisms for the lineage switch remain unclear as does its relation with mixed lineage leukemias, but we believe that drugs employed in our therapy protocol could have had an influence on this conversion. 相似文献

Osteonecrosis (ON) is usually considered treatment related in patients with acute lymphoblastic leukemia (ALL). We report two patients with presentation of ON at the time of ALL diagnosis. Both were females and diagnosed with ALL at age 8 and 14 years. In the latter, some symptoms and radiologically verified ON in both knees were still present after the end of ALL therapy. No pediatric patients have previously been reported with ON presenting before initiation of ALL therapy. 相似文献
