AraC for Newly Diagnosed Adult Langerhans Cell Histiocytosis

2019-10-16 10:39:38 | BioPortfolio


Langerhans cell histiocytosis (LCH) is a rare, heterogeneous histiocytic disorder occurring in patients of all ages from neonates to the elderly. The current standard treatment protocol for children with de novo multisystem LCH is vinblastine plus prednisone. This regimen has never been proven effective for adults in a prospective study, since the only prospective trial evaluating the efficacy of a vinblastine/prednisone regimen in adults was prematurely closed due to unacceptable toxicities. A retrospective study showed an advantage for cytarabine monotherapy compared with vinblastine/prednisone in bone LCH patients. This phase 2, prospective, single-center study is designed to evaluate the efficacy and safety of cytarabine monotherapy in adults with newly diagnosed MS-LCH or LCH with multifocal single system (SS-m) involvement.

Medical and Biotech [MESH] Definitions

General term for the abnormal appearance of histiocytes in the blood. Based on the pathological features of the cells involved rather than on clinical findings, the histiocytic diseases are subdivided into three groups: HISTIOCYTOSIS, LANGERHANS CELL; HISTIOCYTOSIS, NON-LANGERHANS-CELL; and HISTIOCYTIC DISORDERS, MALIGNANT.

A rare form of non-Langerhans-cell histiocytosis (HISTIOCYTOSIS, NON-LANGERHANS-CELL) with onset in middle age. The systemic disease is characterized by infiltration of lipid-laden macrophages, multinucleated giant cells, an inflammatory infiltrate of lymphocytes and histiocytes in the bone marrow, and a generalized sclerosis of the long bones.

A group of disorders resulting from the abnormal proliferation of and tissue infiltration by LANGERHANS CELLS which can be detected by their characteristic Birbeck granules (X bodies), or by monoclonal antibody staining for their surface CD1 ANTIGENS. Langerhans-cell granulomatosis can involve a single organ, or can be a systemic disorder.

Rare malignant neoplasm of dendritic LANGERHANS CELLS exhibiting atypical cytology, frequent mitoses, and aggressive clinical behavior. They can be distinguished from other histiocytic and dendritic proliferations by immunohistochemical and ultrastructure studies. Cytologically benign proliferations of Langerhans cells are called LANGERHANS CELL HISTIOCYTOSIS.

Group of disorders which feature accumulations of active HISTIOCYTES and LYMPHOCYTES, but where the histiocytes are not LANGERHANS CELLS. The group includes HEMOPHAGOCYTIC LYMPHOHISTIOCYTOSIS; SINUS HISTIOCYTOSIS; xanthogranuloma; reticulohistiocytoma; JUVENILE XANTHOGRANULOMA; xanthoma disseminatum; as well as the lipid storage diseases (SEA-BLUE HISTIOCYTE SYNDROME; and NIEMANN-PICK DISEASES).
