Late effects of childhood cancer treatment in long-term survivors diagnosed before the age of 3 years - A multicenter, nationwide study.

Background: The effect of age on the incidence of late sequelae that occur after anticancer treatment in childhood is still not fully elucidated. In this multicenter study of long-term survivors diagnosed before age of three, we investigated the prevalence of late effects many years after treatment.

Methods: The study group (n = 561) was selected from the Polish National Childhood Cancer Survivors Registry (n = 1761) created in 2007.

Analysis of incidence and risk factors of the multidrug resistant gastrointestinal tract infection in children and adolescents undergoing allogeneic and autologous hematopoietic cell transplantation: a nationwide study.

The aim of this multi-center study was to evaluate the incidence, clinical course, and risk factors for bacterial multidrug-resistant (MDR) gastrointestinal tract infections (GTI) among children undergoing allogeneic and autologous hematopoietic cell transplantation. A total number of 175 pediatric patients (aged 1-18 years), transplanted between January 2018 and December 2019, who were tested for bacterial colonization/infection were enrolled into this multi-center analysis. Episodes of MDR GTI occurred in 77/175 (44%) patients.

Melphalan, Etoposide, and Carboplatin Megatherapy with Autologous Stem Cell Transplantation in Children with Relapsing or Therapy-Resistant Extracranial Germ-Cell Tumors-A Retrospective Analysis.

Pediatric germ cell tumors (GCTs) are a group of chemosensitive malignancies with a 90% curability rate. We report a series of children with relapsing or therapy-resistant GCT treated with melphalan-etoposide-carboplatin high-dose chemotherapy (HDCT) and autologous stem cell transplantation. This consisted of 18 children, either with GCTs after relapse (nine patients) or with an unsatisfactory response to first-line chemotherapy (nine patients), who underwent HDCT.

Metabolic Disturbances in Children Treated for Solid Tumors.

Metabolic disturbances are among the most common disorders diagnosed in pediatric patients after anti-cancer therapy (ACT). The aim of our study was to evaluate the prevalence of metabolic disturbances among patients after ACT. The study group comprised 44 patients (31 boys) treated for solid tumors and 31 patients in the control group.

Eltrombopag Therapy in Children With Rare Disorders Associated With Thrombocytopenia.

Eltrombopag (ELT) is a thrombopoietin receptor activator that has shown efficacy in chronic immune thrombocytopenia. We report the outcome of ELT therapy in 4 children who were treated for rare hematologic disorders, including Pearson syndrome, DiGeorge syndrome, posttransplant allogeneic poor graft function (PGF), and Wiskott-Aldrich syndrome. The ELT tolerance in the analyzed group was good, with the exception of the child with Pearson syndrome, who experienced an exacerbation of cataracts and had to discontinue treatment.

Correction to: Health status of Polish children and adolescents after cancer treatment.

The first and family names of the authors were interchanged. The correct author names are now correctly presented in this article.

Health status of Polish children and adolescents after cancer treatment.

Unlabelled: In the last 40 years, considerable progress was made in the treatment of childhood cancer. Nearly 80% of children achieve long-term clinical remission or are permanently cured. This improvement is however not without sacrifice.

Assessment of gonadal function in boys and adolescents at the diagnosis of neoplastic disease.

Objective: We assessed the gonadal function in boys with a newly diagnosed neoplastic disease prior to chemotherapy. Eighty-four boys (48 prepubertal and 36 pubertal) were evaluated, including 50 with acute lymphoblastic leukemia (ALL) or non-Hodgkin lymphoma (NHL), 10 with Hodgkin lymphoma (HL), and 24 with solid tumors. The control group consisted of 24 healthy prepubertal and 24 pubertal boys.

Testicular function after treatment for acute lymphoblastic leukemia (all) in prepubertal and pubertal boys.

Testicular function was evaluated in 59 male (27 prepubertal and 32 pubertal) survivors treated for ALL according to two different protocols. Serum inhibin B, FSH, testosterone, LH, and testicular volume were measured. In both groups the mean values of inhibin B were lower than control, whereas the other analyzed parameters were comparable.

[Gonadal function in young men after the treatment for Hodgkin lymphoma].

Introduction: The survival rate after the treatment for Hodgkin lymphoma improved in the last three decades and the late effects of anticancer therapy, particularly gonadal toxicity, became an important problem.

The Aim Of Work: Assessment of the influence of chemo- and radiotherapy on gonadal function in young male survivors after the treatment for Hodgkin lymphoma (HL).

Material And Methods: Levels of inhibin B, testosterone, FSH, LH and testicular volume were measured in 26 HL survivors aged from 15.

[Testicular function in young men treated in prepubertal period for childhood malignancy].

Introduction: A complex anticancer treatment leads to different late effects e.g. gonadal damage in adulthood.

[Analysis of selected undesirable effects of cytostatic drugs in treatment of the central nervous system tumours in children. Preliminary report].

Introduction: During treatment of children with brain tumours there is a large risk of occurrence of side effects related to the narrow therapeutic range of cytostatic drugs and irradiation of the central nervous system.

Aim: Determination of the patients' risk of undesirable effects and determination of intensification of myelosuppression and hepatocellular damage during treatment of central nervous system tumours, depending on the used therapeutic protocol and the time of chemotherapy.

Material And Methods: The investigated group consisted of 17 patients (5 girls, 12 boys) aged 1.

[Evaluation of selected endocrine complications in patients treated with auto- and allo-haematopoietic stem cell transplantation].

Aim: The aim of this study was to evaluate the endocrine complications, in particular disorders of growth and thyroid function and glucose metabolism dysfunctions in patients treated with allo- and auto-haematopoietic stem cell transplantation (HSCT).

Material And Methods: The investigated group consisted of: I. 16 patients after auto-HSCT (6 girls, 10 boys) aged 3-20 years (average 10,8+/-) because of acute myelogenous leukaemia (n=5), non Hodgkin lymphoma (n=3), neuroblastoma (n=3), embryonal cancer (n=2), medulloblastoma (n=1), Ewing's sarcoma/PNET (n=1), hyper eosinophilic syndrome (n=1).
