non hodgkin's lymphoma

Non-Hodgkin lymphomas

Malignant lymphomas, called "Non-Hodgkin" (NHL), are a heterogeneous group of tumours linked to an abnormal and malignant multiplication of lymphoid cells. The NHL differs from childhood leukemias by the amount of tumor cells in the marrow below 25%. Beyond that figure, we're talking about leukemia.

The NHL is classified according to the cell type involved. These are lymphomas:

of Burkitt;
Lymphoblastic
Anaplastic to large cells;
B diffuse to large cells.
These diseases are rare. They represent 7% of the child's tumors. They are exceptional before 2 years and are preferentially touching the boys. Therapeutic advances in the child's non-Hodgkin lymphomas have been considerable during the last few years as the healing percentage is currently 70 to 90%.

Diagnosis
Non-Hodgkin lymphomas of the child have rapid tumor growth and release. Their diagnostic and therapeutic care must be done in an emergency context.

The diagnosis should be quickly confirmed and the type of lymphoma to be specified; Determine the stage by the initial extension balance; Make the overall assessment and take charge of any immediate complications.

The diagnosis is, on average, at the age of 7 or 8 years. Boys are more often affected than girls, especially in Burkitt lymphomas (2.5 to 3 boys for a girl). The physical signs revealing the NHL depend on its initial location (abdomen, thorax, ent, peripheral ganglia, others).

Treatment
These tumors are very susceptible to chemotherapy, so is it the major therapeutic tool while surgery no longer has its place. Radiation therapy is only used for exceptional indications. Chemotherapy strategies are different depending on the cell type of the NHL.
