Secondary Neoplasms in Children with Hodgkin's Lymphoma Receiving C-MOPP and Radiotherapy: Presentation of Four Cases.

Patients who survive Hodgkin lymphoma (HL) are at increased risk of secondary neoplasms (SNs). A wide variety of SNs have been reported, including leukemias, non-Hodgkin's lymphomas, and solid tumors, specifically breast and thyroid cancers. Herein we report subsequent neoplasms in four patients with HL receiving chemoradiotherapy.

De novo osteogenic sarcoma of mastoid bone.

The most common primary malignant tumor of the bone is osteosarcoma. Primary involvement of the craniofacial bones in osteosarcoma is relatively rare. The mandible and the maxillae are the most commonly affected bones of the head.

High-dose ifosfamide with hematopoietic growth factor support in advanced bone and soft tissue sarcomas.

Aim: Ifosfamide and doxorubicin are the most effective agents in the treatment of sarcomas, although their contributions to survival are usually limited. High-dose ifosfamide can be used as a salvage treatment in patients with recurrent or advanced sarcoma. We evaluated efficacy and toxicity of high-dose ifosfamide in the patients with recurrent or advanced sarcoma in this study.

Trace Element Analyses (Zinc and Selenium) in Pediatric Malignant Lymphomas.

Ninetysix untreated patients with Malignant lymphoma's, 81 Hodgkin's disease and 15 Burkitt's lymphoma were studied for zinc (Zn) and selenium (Se) status. Plasma and hair Zn, and Se levels were measured by atomic absorption spectrophotometry. Chronic Zn and Se deficiencies (low plasma and low hair Zn and Se levels together) were found to be associated with Malignant lymphoma's in Turkish children.

Characteristics of "Early Type-I Pattern" (0-6 years) Hodgkin's Disease in Turkish Children.

The clinico-epidemiologic characteristics of 54 children with HD in 0-6 years of age group were retrospectively analyzed. This group represented 27% of 200 HD cases observed in our center and was named as early type-I pattern HD. The association of EBV with HD was also shown by serologic and immunohistochemical methods (LMP1) in these very young Turkish patients.
