Lymphoma is the third most common cancer in children and adolescents. Non-Hodgkin's lymphomas comprise a heterogeneous group of tumors with distinct pathologic and clinical characteristics. Over the past three decades, significant advancements have been made in the molecular characterization of these disorders. With the use of intensive multiagent chemotherapy, non-Hodgkin's lymphomas are now a...

Changes in monocyte functions have been described in several human malignancies. The monocyte/macrophage system is known to play a crucial role in the rejection of tumor cells and phagocytosis represents an important defense mechanism used by these cells. This paper reports the adherence power and phagocyting ability (latex beads) of circulating monocytes in 20 patients with unresectable non-sm...

We report a case of extraskeletal osteosarcoma (ESOS) and autopsy findings. A 35-year-old man presented with an ossified tumor in the right thigh and lung metastasis. The lung tumors continued to develop despite multiagent chemotherapy and caused death within 8 months. Autopsy revealed many secondary lesions in the lungs, especially in the left lung. Histopathologically, the primary tumor and o...

Acute lymphoblastic leukemia (ALL), the most common type of cancer in children, is a heterogeneous disease in which many genetic lesions result in the development of multiple biologic subtypes. Today, with intensive multiagent chemotherapy, most children who have ALL are cured. The many national or institutional ALL therapy protocols in use tend to stratify patients in a multitude of different ...

Patients with myeloma are at risk for serious and life-threatening thromboembolic events because of their disease, individual risk factors, and antimyeloma or other medications. The International Myeloma Foundation's Nurse Leadership Board developed this consensus statement for assessment and prevention of thromboembolic events. Prophylactic measures are categorized as mechanical, regimen relat...

Osteosarcoma is the bone tumor that most commonly affects children, adolescents, and young adults. Before 1970, treatment primarily included surgical resection. However, the introduction of chemotherapy led to a dramatic improvement in prognosis for patients with localized osteosarcoma; long-term survival rates of less than 20% improved to 65% to 70% after the advent of multiagent chemotherapy ...
