This is especially important in childhood when, in addition to the treatment of the underlying disease, it is necessary to ensure the normal growth and development of the child.\u0000Objective: The aim of this paper was, based on a review of the literature, to point out the importance and show the basics of nutritional assessment and monitoring, as well as nutritional interventions in children suffering from malignant diseases.\u0000Methods: The available scientific and professional literature (PubMed) for the last 10 years was searched, and the following keywords were used: nutrition, malignant disease, diet, nutritional assessment, and nutritional intervention. All received abstracts were screened and selected were publications that included above keywords as a main topic.\u0000Results: Based on the reviewed literature, presented are the basics of nutritional assessment and when to perform it, risks for nutritional disorders and available nutritional interventions.\u0000Conclusion: In pediatric oncology patients, it is important to carry out a nutritional assessment not only at the time of diagnosis, but also during the further course of treatment and follow-up of the patient, to determine individual nutritional interventions that will prevent or treat an already occurring nutritional disorder, and to ensure the growth of the child in accordance with the genetic potential.","PeriodicalId":49715,"journal":{"name":"Paediatria Croatica","volume":"143 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141810836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our survey aimed to establish to what extent pharmacogenetics has already been utilised in everyday work.Methods: A retrospective survey on pharmacogenetic testing in children treated for malignancies at the Department of Oncology and Haematology, Children’s Hospital Zagreb, from 2021 to 2023 was carried out.Results: Pharmacogenetic testing was performed in 17.2% of the 180 children (53.3% female, median age 7.0 years), the greatest number of tests obtained in 2023. Preemptive testing included thiopurine S-methyltransferase polymorphisms (in 94.4% of children with acute lymphoblastic leukaemia and 33.3% with eosinophilic granuloma) and methylenetetrahydrofolate reductase gene poly-morphisms assaying (in 55.6% of acute lymphoblastic leukaemia and 23.1% of osteosarcoma patients). In 8 children, pharmacogenetic testing was made due to adverse events (25% lung and 75% liver injury, all grade 4), in the majority of cases presumably related to vincristine. Pharmacogenetic testing results were pathological in all reactively tested patients, requiring dose modification/chemotherapeutics omission in 87.5% of cases.Conclusion: The number of pharmacogenetic assays performed due to high-grade adverse events in children with cancer has been continuously rising, steering otherwise standardised treatment towards a more individualised approach. Preemptive thiopurine Methyltransferase Polymorphism testing has been routinely done in almost all patients planned to receive thiopurines. However, more research is needed on drug-gene pairs in the field of paediatric oncology to minimise treatment-related toxicity and optimise treatment outcomes.","PeriodicalId":49715,"journal":{"name":"Paediatria Croatica","volume":"9 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141813514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The surgical techniques we use in the diagno-sis and treatment of childhood tumors continuously evolve according to a specific type of tumor. Methods that were also previously acceptable are now becoming more and more meticulous to preserve the patient’s quality of life and fertility. Surgical techniques include tumor biopsy methods, surgery of tumor`s primary site (extirpation of tumors, resection of organs or organ systems), staging of tumors according to anatomic extension, operations for disease relapse and metastases, and palliative and supportive procedures. The role of surgery in the prophylaxis of oncological disease is also well defined for various predisposing syndromes and diseases. The most important aspect of surgical oncological treatment is strict adherence to and familiarity with the protocol for a certain type of tumor, as well as a multidisciplinary and individual approach to the pediatric oncologic patient.","PeriodicalId":49715,"journal":{"name":"Paediatria Croatica","volume":"136 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141811232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"PET/CT in diagnosis and monitoring the effect of treatment in children with malignant tumors","authors":"Sunčana Divošević","doi":"10.13112/pc.2024.18","DOIUrl":"https://doi.org/10.13112/pc.2024.18","url":null,"abstract":"PET/CT is the most sensitive and highly specific imaging technique for determining the location of tumors, primary tumors of unknown location, determining the extent and activity of malignant disease, monitoring treatment effects, detecting local recurrence and distant malignancy, precise planning of various treatment modalities and planning/determining the radiation field. PET uses biologically active molecules labeled with short-lived radionuclides that emit positrons and are the product of nuclear reactions in a cyclotron. Fluorine-18 (18F) is the most commonly used radionuclide in nuclear medicine, and its relatively long half-life of 110 minutes allows adequate synthesis of radiopharmaceuticals and monitoring of biological processes, as well as delivery to PET machines in remote facilities. The most commonly used radiopharmaceutical, which is now used in clinical practice in more than 90% of PET/CT examinations, is 2-(18F)-fluoro-2-deoxy-D-glucose (18F FDG), a glucose derivative that reflects the accumulation and consumption of glucose in cells, i.e. glucose metabolism. PET/CT has an advantage over other diagnostic imaging techniques because by combining PET, which is the evaluation of the intensity of the metabolic activity of a specific radiopharmaceutical in the cells, and CT, which shows the anatomy and morphology of the organs, we simultaneously obtain information about pathological abnormalities in both the function and morphology of the lesions or organ and the presence of viable tumor or inflammatory tissue. It is important to mention that with the latest PET/CT equipment we have the possibility to visualize metabolic activity even in very small lesions (2 mm). The advantage of this diagnostic method is that the findings are not only analyzed visually, but also quantitatively by measuring the intensity of radiopharmaceutical accumulation in the lesions, thus achieving objectification of the findings and the possibility of adequately monitoring the effect of different forms of treatment in control imaging. PET/CT allows us to identify prognostically risky patients and to select the most appropriate forms of treatment for each individual patient. PET/CT is the most sensitive method for distinguishing treatment-related changes from residual or recurrent disease. A continuous decrease in metabolic activity in the tumor area indicates a positive effect of the treatment. PET/CT enables precise monitoring of the effect of all forms of treatment (surgical, chemotherapeutic, radiotherapeutic and radiosurgical procedures) and has the advantage that the entire body is captured and analyzed with one image in the field of view and not just a single segment. The radiation exposure in PET/CT results from the use of radiopharmaceuticals and CT imaging, and the ALARA principle (as low as reasonably achievable) is followed, whereby the dose is adjusted taking into account the weight and age of the child and the type of device, taking into account the ","PeriodicalId":49715,"journal":{"name":"Paediatria Croatica","volume":"123 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141811832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Milavić, Sven Seiwerth","doi":"10.13112/pc.2024.17","DOIUrl":"https://doi.org/10.13112/pc.2024.17","url":null,"abstract":"Osteosarcoma is the most common primary tumor of the bone with the highest incidence in the first two decades of life. The incidence rate with 95% confidence is 4 for the range of 0-14 and 5 for the range of 0-19 cases pre million per year. Osteosarcoma is a rare malignant mesenchymal tumor with presence of mesenchymal cells and production of osteoid matrix (1). Distinct histological subtypes have been defined, but the biological behavior and the conventional approach to treatment have been similar for last couple of decades without improvement in outcome. The biology of osteosarcoma is characterized with a high rate of lung metastasis. Disorganized genome seems to be the best description of genetic aberrations and changes in gene expression in osteosarcoma, with the most consistent finding, beside the p53 and RB dysregulation,significant aneuploidy and some evidence of massive disruption in the chromosomal structure (2). The metastatic cascade represents a process where cell leaves primary tumor and invades the surrounding tumormicroenvironment with intravascular and also extravascular invasion to the distant sites enabling the blood supply and growth to the secondary site and reengage to the new microenvironment.  Meanwhile, metastaticcell could be dormant in the „protective“ environment and then move to the secondary distant sites (3). The microscopic metastases are usually responsible for disease progression, so targeting geneticand epigenetic alterations will certainly improve the outcome (2). Recent studies showed that metastatic clones often do not correspond to the dominant clones in the primary tumor, but may evolve monoclonal and polyclonal, showing the clonal/subclonal heterogeneity of osteosarcoma. At the same time, immune response is a complex process that combines recognition of tumor cells, and response of effector and regulatory immune cells. Tumor cells by soluble factors secretion lead to downmodulation of the immune system. The well known immune „escape“ is the hallmark of cancer when immune system play a dual function, slowing down the tumor progression at first and then facilitating the tumor growth after the modelling phase of tumor cells. How to switch immunotolerance which contribute to permissive microenvironment beneficial for tumor cells to immunocompetent environment, is the challenge of immunotherapy (4). Two mains immunotherapeutic approaches are proposed for bone sarcomas. The first one is based on targeting the pro-tumoral effectors including M2 macrophages, i.e. muramyl tripeptide phosphatidylethanolamine (MTP-PE), interferon gamma (IFNγ) and the molecules associated with immune checkpoints; programmed death-ligand 1 (PD-L1) with it's receptor, programmed cell death protein (PD1) and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4). The other one is based on the stimulation of anti-tumoral effectors; dendritic cells (DC), nitrogen containing bisphosphonates (N-BPs) and natural killer cells (NK).
