Radiation late effects in children treated for orbital rhabdomyosarcoma.

Background And Purpose: The experience resulting from large cooperative studies shows that correct radiation therapy at doses adequate to the tumor bulk are crucial for local control of rhabdomyosarcoma. The aim of the present study was to document the correlation between modalities and doses of radiotherapy and radiation side effects.

Patients And Methods: Between 1980 and 1997, 19 patients affected by primary orbital rhabdomyosarcoma have been followed at the University Federico II of Naples.

Primary Ewing's sarcoma of the maxilla, a rare and curable localization: report of two new cases, successfully treated by radiotherapy and systemic chemotherapy.

Primary maxillary localization of Ewing's sarcoma is unusual. Involvement of facial bones is characterized by clinical and radiological features distinct from those commonly observed in other sites. Because of the above peculiarities a delay in diagnosis and thus in starting treatment is very probable in such cases.

Granulocytic sarcoma in nonleukemic children: report of two new cases successfully treated by local radiation therapy and systemic chemotherapy.

Granulocytic sarcoma (GS) is a rare tumor composed of immature myeloid cells. Exceedingly rare in childhood, it has more commonly been described in association with acute myeloid leukemia. Occasional nonleukemic patients generally go on to develop overt leukemia in a mean period of 10.

Lymphoblastoid interferon alfa treatment in chronic hepatitis C.

Interferon is becoming the standard treatment in adults for chronic hepatitis C. Twenty one children with histologically proved chronic hepatitis C (10 boys, range 2.5-13 years), who were otherwise healthy, were enrolled in a randomised controlled study to test their response to interferon alfa.

Lack of intrafamilial transmission of hepatitis C virus in family members of children with chronic hepatitis c infection.

Intrafamilial transmission of hepatitis C virus (HCV) was studied in family members of 44 children with chronic hepatitis C infection (index cases). There were 22 males and the mean age of all patients was 9.5 years (range, 1.
