abnormalities of the thyroid gland are among the most frequent endocrine complications observed in childhood cancer survivors. we report an 11 years old girl who developed central hypothyroidism and acth deficiency during the chemotherapy for cns relapse of acute lymphoblastic leukemia before receiving radiotherapy. keywords: thyroid gland, hypothyroidism, chemotherapy, acute lymphoblastic leuk...

NUDT15 genetic variants and 6-mercaptopurine intolerance in pediatric acute lymphoblastic leukemia: an updated review

background this cross sectional study was performed to evaluate dental ages and incidence of dental anomalies in children treated for acute lymphoblastic leukemia (all). methods and materials a total of 25 all patient who passed at least 2 years of chemotherapy and 25 healthy sex and age matched children were evaluated. dental age as well as dental anomalies in shape, size, number, and structur...

True histiocytic lymphomas (THLs) are rare tumors in which the malignant cells show morphologic and immunophenotypic evidence of histiocytic differentiation. We describe THLs that arose after therapy for one case of T-lineage lymphoblastic lymphoma (LyL) and two cases of acute lymphoblastic leukemia (ALL) (both CD10+, one pre-B phenotype). The lymphoblastic neoplasms were not unusual in any way...

neuroblastoma is the most common extracranial solid tumor in children. the co- occurrence of neuroblastoma and acute lymphoblastic leukemia is rare. we report a rare case of advanced-stage neuroblastoma in a 3.5-year-old girl that was accompanied by acute lymphoblastic leukemia following treatment. her leukemia may have been due to chemotherapy (secondary leukemia) or may have been de novo.

Relapsed acute lymphoblastic leukemia is the most common cause of cancer-related mortality in young people and new therapeutic strategies are needed to improve outcome. Recent studies have shown that heterozygous inactivating mutations in the histone acetyl transferase, CREBBP, are particularly frequent in relapsed childhood acute lymphoblastic leukemia and associated with a hyperdiploid karyot...

BACKGROUND Studies from various countries have found an increasing incidence of childhood leukemia in recent decades. To characterize time trends in the age- and sex-specific incidence of childhood acute leukemia during the last 20 years in the Nordic countries, we analyzed a large set of population-based data from the Nordic Society of Paediatric Haematology and Oncology (NOPHO) in their acute...

Osteonecrosis is one of the most common, serious, toxicities resulting from the treatment of acute lymphoblastic leukemia. In recent years, pediatric acute lymphoblastic leukemia clinical trials have used discontinuous rather than continuous dosing of dexamethasone in an effort to reduce the incidence of osteonecrosis. However, it is not known whether discontinuous dosing would compromise antil...

abstract background leukemia is the most prevalent childhood cancer and acute lymphoblastic leukemia (all) constitutes 75% of all cases. the most frequent presenting symptoms are fever, weight loss and pallor. early detection of clinical symptoms positively affects timely diagnosis. the objectives of the present study were to assess frequency of presenting symptoms, laboratory data, immune phen...

adipose tissue secretes a large number of adipocytokines such as leptin, resistin, and adiponectin. many of these hormones and cytokines are altered in obese individuals and may lead to disruption of the normal balance between cell proliferation, differentiation, and apoptosis. the aim of our work was to investigate the disturbance of secretion of adiponectin and resistin in de novo and relapse...
