[Acquired Fanconi-de Toni-Debre syndrome due to therapy for Ewing's sarcoma in 5-years old boy].

We present a 5-years old boy with acquired Fanconi-de Toni-Debre syndrome being a effect of therapy for Ewing's sarcoma. At the age of 3 years, this boy was diagnosed as suffering from Ewing sarcoma of his right femur. The boy received a course of 8-month pre-surgery (6 VIDE--Vincristine, Ifosfamide, Doxorubicin, Etoposide cycles and 2 VAI--Vincristine, Actinomycin, Ifosfamide cycles) and 6-month post-surgery (6 VAI--Vincristine, Actinomycin, Ifosfamide cycles) cytostatic therapies according to EWING, EURO 99 protocol.

[Soft tissue sarcomas of bladder and prostate in children treated according to the CWS-96 protocol--report of the Polish Paediatric Solid Tumours Study Group].

Aim: analysis of the course, outcome and therapy complications in bladder/prostate soft tissue sarcomas (STS) in children treated from I'1997 to II'2003 according to CWS-96 protocol in Poland.

Material And Methods: 22 children (M/F: 17/5, age: 8 months - 17 years 2 months; median 5,3y). Histopathology: RMS-20 patients (RME-14), non-RMS-2 patients.

[Solid neoplasms localised within the parameningeal region and CNS infiltration].

Introduction: Solid neoplasms primarily localised within parameningeal region constitute a significant diagnostic and therapeutic problem. Solid tumours developing in the primary site are soft tissue sarcomas (STS) and lymphoepithelioma.

Aim Of Study: Evaluation of the incidence of CNS infiltration, histological type of tumour and results of treatment.

[Malignant neoplasms localised in the parameningeal region in children treated at two Polish oncological centres-diagnostic and therapeutic dilemmas].

Unlabelled: Malignant neoplasms localized in the parameningeal region include mainly soft tissue sarcomas (MTM), non-Hodgkin s lymphomas (NHL-B) and, less frequently, nasopharyngeal carcinomas. The aim of the study was to analyze diagnostic and therapeutic problems in children with parameniingeal neoplasms treated in Departments of Paediatric Oncology in Gdansk and Lublin between 1992 and 2004.

Material And Methods: The study includes 32 patients (M/F: 23/9), aged 2 to 17 years, mean 6,3 years.

[Results of treatment for osteosarcoma in children and youth].

Bone tumours comprise about 5% of childhood neoplasms. Osteosarcoma is the most common sub-type and constitutes 60 % of all bone cancers. Incidence is similar in girls and boys and is increasing steeply with age.

[Non-Hodgkin lymphomas of the nasopharynx in children--diagnostic and therapeutic difficulties].

Unlabelled: About 7% of all childhood cancers comprise non-Hodgkin's lymphoma (NHL). NHL are heterogenous group of neoplasms deriving from lymphatic system (cell B and T). B-cell NHL characterize by high malignancy, but coincidentally good reaction for treatment.

[Central nervous system metastases in children with solid tumours].

Background: Central nervous system (CNS) metastases occur in 20-30% of adult patients with systemic cancers. but they rarely occur in children with solid tumours.

Aim: clinical and prognostic characteristics of CNS recurrence in children treated for solid tumours were analysed.

Characteristics and outcome of children with primary soft tissue sarcomas of extremities.

Objectives: To determine the characteristics and outcome or patients with primary soft tissue sarcomas of extremities in children.

Material And Methods: Thirty-six patients treated for soft tissues sarcomas were enrolled into the study. Features analysed: the incidence of soft tissues sarcoma of extremities, the time from first clinical symptoms to making the diagnosis, the primary site of tumour; histopathologic type of tumour, stage of disease, methods and results of the treatment.

[Malignant pelvic neoplasms in children treated in two Polish oncology centres].

Background: Extensive diagnostic and therapeutic dilemmas appear in children With primary malignant neoplasms located in the minor pelvis.

The Aim Of The Study: To evaluate the clinical symptoms, disease course and the results of treatment in patients with malignant pelvic neoplasms.

Material And Methods: The study included 31 children (13 boys and 18 girls; aged 2 months to 16 years; mean age -- 8 years) treated in the Departments of Paediatric Oncology and Haematology in Gdansk and Lublin during the period of 1992-2003.

Outcome of Ewing sarcoma in children and adolescents with Ewing sarcoma: a five-year survival from a single institution.

Ewing sarcoma, together with neuroblastoma and central nervous system tumors, has got the lowest percentage of complete cure among all malignant diseases in children. From 1993 to 2003, 26 patients with Ewing sarcoma were treated in Pediatric Hematology and Oncology Department, Medical University in Lublin, Poland. In this study the character and time of the clinical symptoms to making the diagnosis, the abnormalities of laboratory tests, and the primary site of tumor were analyzed.

Solid tumours of perimeningeal region in children--diagnostic and therapeutic difficulties.

Thirteen patients, aged 2-17 years, were treated because of primary solid tumours of head and neck location at the Department of Children Hematology and Oncology in Lublin. The authors analyzed clinical symptoms before diagnosis and the duration of these symptoms as well as the kind of tumours. In all cases the tumour was diagnosed on histopathological examination: soft tissue sarcomas--9 children, lymphoepithelioma--4 ones.

Primary chest tumours in children.

Primary chest tumours in children are rare and appear in 3% of cases, 83% of which are malignant. Early diagnosis is very difficult because of delayed symptoms and highly advanced stage. Symptoms of chest tumours depend on the tumour mass, localization and time of progression.

[Incidence of childhood solid tumours in Lublin region from 1988 to 2000].

The purpose of this study was the analysis of number and structure of new solid tumours and tumour morbidity among children 0-17 years old, in the Lublin Region of Poland, from 1988 to 2000. The analysis was based on sex, age and place of domicile (urban/rural region). During this time in the Lublin Region 344 cases of childhood solid tumours were reported; it was 36.
