BACKGROUND: Survivors of acute lymphoblastic leukemia (ALL) may experience endocrine dysfunction. This study evaluated growth and pubertal patterns in survivors of childhood ALL. METHODS: Longitudinal assessment of anthropometric measurements and pubertal status was performed in a retrospective cohort of survivors (n=183). Median age at last endocrine visit was 16.1 years (range 8.2-27.6); median follow-up time was 8.7 years (range 3-21.4). RESULTS: Treatment with chemotherapy+prophylactic cranial radiation (pCRT, n=29) was associated with lower mean height standard deviation score (SDS) than chemotherapy alone (n=154) (p=0...

In the past, increases in childhood cancer incidence were reported in Europe and North America. The aim of this study is to show updated patterns of temporal behavior using data of the Childhood Cancer Registry of Piedmont (CCRP), a region with approximately 4.5 million inhabitants in North-West Italy. CCRP has been recording incident cases in children (0-14 years) since 1967 and in adolescents (15-19) since 2000. Time trends were estimated as annual percent change (APC) over the 1976-2011 period for children, and over 2000-2011 for both children and adolescents...

Achieving lower morbidity and higher survival rates in the treatment of childhood leukemia has been a paradigm of success in modern oncology. However, serious long-term health complications occur in very large populations of childhood leukemia survivors, in the case of both acute lymphoid leukemia and acute myeloid leukemia (AML). Additionally, 15% of acute lymphoid leukemia patients have treatment failures, and rates are even higher in childhood AML. In the last few decades, as a result of well-tested experiments that statistically analyzed treatment cohorts, new agents have emerged as alternatives or supplements to established treatments, in which high survival and/or less morbidity were observed...

BACKGROUND: Acute Lymphoblastic Leukemia (ALL) has a high survival rate, but cancer-related late effects in the early post-treatment years need documentation. Hospitalizations are an indicator of the burden of late effects. We identify rates and risk factors for hospitalization from five to ten years after diagnosis for childhood and adolescent ALL survivors compared to siblings and a matched population sample. METHODS: 176 ALL survivors were diagnosed at ≤22 years between 1998 and 2008 and treated at an Intermountain Healthcare facility...

As long-term survival is high for children and young adults diagnosed with leukemia and lymphoma, delineating maternal, fetal and offspring health risks is important to their family planning. This systematic review examined data comparing these health risks between leukemia and lymphoma survivors and women without a history of cancer. Following a search of Embase, PubMed, CINAHL, Cochrane, and Web of Science, 142 articles were screened and 18 were included in this review. No higher risks of spontaneous abortion, maternal diabetes and anemia, stillbirth, birth defects, or childhood cancer in offspring were observed in survivors compared to controls...

Though acute lymphoblastic leukemia (ALL) is the most common malignancy of childhood age, it is a rare diagnosis in adults. This disease often manifests with common and nonspecific symptoms, so it can easily escape an early diagnostics without a proper blood count examination. We present a case of an adult ALL patient suffering only from severe hips and thighs pain, without any significant blood count abnormities leading to the diagnostics. In the second part of the article, we summarize current highlights regarding this disease...

Vincristine (VNC) is commonly used to treat pediatric cancers, including the most prevalent childhood malignancy, acute lymphoblastic leukemia. Although clinical evidence suggests that VNC causes peripheral neuropathy in children, the degree to which pediatric chemotherapeutic regimens influence pain sensitivity throughout life remains unclear, in part because of the lack of an established animal model of chemotherapy-induced neuropathic pain during early life. Therefore, this study investigated the effects of VNC exposure between postnatal days (P) 11 and 21 on mechanical and thermal pain sensitivity in the developing rat...

BACKGROUND: The incidence of childhood cancers has been increasing and environmental exposure to air toxics has been suggested as a possible risk factor. This study aims to explore ambient exposure to dichloromethane (methylene chloride). METHODS: We frequency matched by birth year approximately 20 cancer-free controls identified from birth records to all childhood cancers ages 0-5 in the California Cancer Registry diagnosed from 1988 to 2012; i.e. 13,636 cases and a total of 270,673 controls...

BACKGROUND: Though the association between parental age at child's birth and the risk of childhood cancer has been previously investigated, the evidence to date is inconclusive and scarce for rarer cancer types. METHODS: Cancer cases (N=5,856) were selected from all children born from 1968 to 2014 and diagnosed from 1968 to 2015 in Denmark at less than 16 years of age listed in the nationwide Danish Cancer Registry. Cases were individually matched to controls (1:100) on sex and year of birth with a total of 585,594 controls randomly sampled from all live births in Denmark from the Danish Central Population Registry...

BACKGROUND: Compromised physical fitness and cognitive difficulties have been reported as late effects of cancer treatment during childhood. To assess this issue, the military rankings of cancer survivors in medical checkups at call-up, and conscripts' physical and cognitive performance during the first weeks of compulsory military education were compared to those of matched population controls without a history of cancer. MATERIAL AND METHODS: A total of 1680 male patients born between 1960 and 1992 with a malignancy diagnosed before the age of 16 who were alive at the call-up age (18 years) were identified using the Finnish Cancer Registry, and five age, sex and place of residence matched controls for each patient using the Population Register Centre...

The aim of the present work was to assess whether polymorphisms in genes coding for drug transport proteins may influence dosing, efficacy and toxicity of maintenance therapy with methotrexate (MTX) and 6-mercaptopurine (6MP) in childhood acute lymphoblastic leukemia (ALL). A total of 41 children with ALL were screened for 10 SNPs in the SLC19A1, ABCB1, ABCC2, ABCC4 and ABCG2 transporter genes by means of direct sequencing. Carriers of the ABCC4 934CC and ABCB1 1236TT genotypes received a lower percentage of the protocol-recommended starting dose of MTX (62...

Mitochondria produce adenosine triphosphate (ATP) for energy requirements via the mitochondrial oxidative phosphorylation (OXPHOS) system. One of the hallmarks of cancer is the energy shift towards glycolysis. Low OXPHOS activity and increased glycolysis are associated with aggressive types of cancer. Mitochondria have their own genome (mtDNA) encoding for 13 essential subunits of the OXPHOS enzyme complexes. We studied mtDNA in childhood acute lymphoblastic leukemia (ALL) to detect potential pathogenic mutations in OXPHOS complexes...

BK viras is a human polyoma viras. It is acquired in early childhood and remains life-long latent in the genitourinary system. BK virus replication is more common in receiving immunosuppressive therapy receiving patients and transplant patients. BK virus could cause hemorrhagic cystitis in patients with allogeneic stem cell transplantation. Hemorrhagic cystitis is a serious complication of hematopoietic stem cell transplantation. Hemorrhagic cystitis could cause morbidity and long stay in the hospital. Diagnosis is more frequently determined by the presence of BK virus DNA detected with quantitative or real-time PCR testing in serum or plasma and less often in urine...

At present, acute myeloid leukemia (AML) accounts for about 15%-20% of childhood acute leukemia. Although overall survival rate is increasing with the help of risk stratification, stratification of chemotherapy, and supportive treatment, conventional pharmacotherapy still has a limited clinical effect and certain limitations in improving remission rate in previously untreated patients and reducing recurrence after remission. With the development of precision medicine, the mechanisms of targeted therapy, including abnormal activation of AML-related signaling pathways and epigenetic modification, have been found in recent years...

Vincristine is a widely used chemotherapeutic agent in the treatment of childhood malignancies. Neuropathy is the most common adverse effect. CYP3A4 and CYP3A5 enzymes of cytochrome p450 enzyme system are responsible in vincristine metabolism. Genetic polymorphism may alter the vincristine metabolism and the neurotoxicity rate. In this study, distribution of CYP3A5 alleles among Turkish children with malignancies, relation between CYP3A5 genotype and neurotoxicity rates, as well as severity and duration of neuropathy and total vincristine doses were investigated...

Beth Faiman, Matthew Faiman
Patients with hematologic cancers such as leukemia, lymphoma, and multiple myeloma are living longer than ever. The survival rate of patients with most hematologic cancers has doubled since 1974, and these once-terminal diagnoses are now chronic health conditions. This article reviews the care of patients with hematologic cancers, including those previously treated for childhood, adolescent, and young-adult cancers, discusses the role of primary care in a multidisciplinary team approach, and reviews innovative ways to deliver needed care...

Hypercalcemia and severe osteolytic lesions are rare complications of acute lymphoblastic leukemia (ALL) in childhood. We report a case of a 3 years old boy who presented with prolonged fever, nausea, vomiting and increasing lower limbs pain. Skeletal X-rays and CT scan showed severe osteolytic lesions of the skull and extremities. Her physical examination showed multiple cervical lymph nodes. In laboratory tests, he had severe hypercalcemia. Parathyroid hormone (PTH) was not elevated. Despite the absence of circulating blasts, bone marrow biopsy revealed B-precursor (ALL)...
