Multicenter retrospective analysis of various primary pediatric malignant hepatic tumors--management in a series of 47 Polish patients (1985-1995).

Forty-seven children treated in various Polish centers between 1985 and 1995 for primary malignant liver tumors were retrospectively analyzed. Hepatoblastoma (HB) prevailed--it was found in 39 cases. There were 6 hepatocarcinoma (HCC) cases and 2 cases of undifferentiated sarcoma (UDS). In 44% of HB patients the tumor involved both liver lobes. 18% of children with HB presented with pulmonary metastases at diagnosis. Chemotherapy was applied in 92% of cases (preoperatively in 67%). Tumor resection was performed in 56% of HB patients. Overall survival of patients with hepatoblastoma was 43.6%, while it was 50% for hepatocarcinoma and 100% for undifferentiated sarcoma (2 cases only). Mean observation time was 58 months. The hepatoblastoma subgroup, being the largest (83% of all cases), was analyzed separately for prognostic factors. Completeness of tumor excision strongly influenced survival. Involvement of both lobes of the liver and multifocality of the tumor were other adverse prognostic factors.

Association of inflammatory pseudotumor of the liver and Papillon-Lefevre syndrome--case report.

A case of hepatic inflammatory pseudotumor mimicking malignancy in a 4-year-old girl with the Papillon-Lefevre syndrome (PLS) is reported. Only recently, an association between this inherited syndrome and liver abscesses has been found. Its possible pathogenesis is discussed and immunologic defects resulting from the Papillon-Lefevre syndrome are presented. The development of inflammatory pseudotumor of the liver might be caused by immunologic disturbances and staphylococcal infection. The picture of the hepatic tumor on imaging in patients with PLS should be attributed rather to inflammatory than neoplastic process.

Cytogenetic findings in an embryonal sarcoma of the liver.

An undifferentiated embryonal sarcoma (malignant mesenchymoma) of the liver from a 5-year-old girl was found to have near-triploid and near-hexaploid clones with several chromosomal rearrangements. This is the first description of the chromosomal changes in this tumor type.

Association of Klinefelter syndrome and abdominal teratoma: a case report.

Extragonadal germ cell tumors are rare. The association with Klinefelter syndrome has become observed recently. A case of an 11-month-old infant with Klinefelter syndrome and a retroperitoneal mature teratoma is presented. In the tumor and lymphocytes, a 47,XXY karyotype was found. The association of Klinefelter syndrome with germ cell tumors and its possible explanations are discussed.

[Ethyol (amifostine): application trial in pediatric oncology].

UNLABELLED: Myelotoxicity is one of the major chemotherapeutic side effects. In some adult and paediatric studies it has been shown that amifostine protects bone marrow from toxic effects of alkylating agents and platinum compounds without reduction in overall cytotoxic action. AIM OF THE STUDY: To test an efficacy of amifostine as a myeloprotectant in multiagent chemotherapy containing alkylating agents or platinum analogues. Amifostine was used in 8 children from 3 to 15 yrs of age treated with chemotherapy (CHT) for cancers. It made total number of 28 courses. Amifostine was administered every other CHT course in a dose of 750 mg/m2. The degree of myelotoxicity measured at nadir was compared between with- and without amifostine CHT courses. Anaemia, leucopenia and thrombocytopenia of WHO grades I and II were qualified as mild toxicity while grades III and IV were recognized as severe. RESULTS: Severe anaemia, leucopenia and thrombocytopenia were found after 3/14 (21%), 8/14 (57%) and 6/14 (43%) courses with amifostine. Proportion of these side effects in identical CHT courses without amifostine in the same pts. was as followed: 1/14 (7%), 7/14 (50%) and 9/14 (64%). Differences among both groups were statistically significant (p = 0.025). Mild side effects (nausea, vomiting, transient hypotension) accompanied amifostine administration in 29% of courses (4/14). CONCLUSION: Preliminary results suggest that amifostine decreased the number of severe thrombocytopenias after CHT. The drug was well tolerated by children.

[Anti-reflux ureteral grafting to the ileum by the Hassan Abol-Enein technique used in augmentation cystoplasty. Preliminary remarks].

The new technique of anti-refluxing uretero-ileal reimplantation in augmentation cystoplasty was applied. The operation was performed in patient with neurogenic bladder and left-sided vesicoureteral reflux Vo resulting from myelomeningocoele. Augmentation of the bladder and disappearance of vesicoureteral reflux was attained with good results at 1 year follow-up.

Clinical course and treatment of pheochromocytomas in children. Analysis of five cases.

Between 1965 and 1990 five children with pheochromocytomas were treated. Clinical course, methods of diagnosis, treatment and results established by follow-up from 6 months to 20 years are presented. Hypertension and headaches occurred in all patients. One child with a malignant form of pheochromocytoma manifested central nervous symptoms imitating epilepsy and additionally diffuse pulmonary metastases were found. One patient had a family history of pheochromocytomas and presented with hypermetabolic state and neurovegetative symptoms. One child had multifocal tumors: two in the posterior mediastinum and one in the retroperitoneal space. All patients were treated by either enucleation of the tumor, tumor excision or adrenalectomy. One child died 12 years after surgery from the rapid progression of pulmonary metastases of pheochromoblastoma present at the time of diagnosis.

[Congenital bifid sternum (author's transl)].

The authors give a short description of the frequency and types of the rare deformities of the sternum. Following a detailed presentation of the various methods of treatment, three of their own observations, one of them an ectopia cordis, are given as case-reports. Two of these patients have already been observed over a long period.
