The more aggressive forms of disease require treatment with chemotherapy, radiotherapy, immunotherapy and—in some cases—a bone marrow transplant. The use of rituximab has been established for the treatment of B-cell–derived hematologic malignancies, including follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL).
A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from pressure. [1]
A myeloid sarcoma (chloroma, granulocytic sarcoma, [1]: 744 extramedullary myeloid tumor) is a solid tumor composed of immature white blood cells [2] called myeloblasts. A chloroma is an extramedullary manifestation of acute myeloid leukemia ; in other words, it is a solid collection of leukemic cells occurring outside of the bone marrow .
The proposed criteria for SPB is the presence of a single bone lesion, normal bone marrow (less than 5% plasma cells), small or no paraprotein, no related organ involvement/damage and a normal skeletal survey (other than the single bone lesion). The criteria for extramedullary plasmacytoma are the same but the tumor is located in soft tissue.
When one tumor is present, it is called a plasmacytoma; more than one is called multiple myeloma. [10] Multiple myeloma is diagnosed based on blood or urine tests finding abnormal antibody proteins (often using electrophoretic techniques revealing the presence of a monoclonal spike in the results, termed an m-spike), bone marrow biopsy finding ...
Acute myeloid leukemia (AML) is a type of cancer affecting blood cells that eventually develop into non-lymphocyte white blood cells. The disease originates from the bone marrow, the soft inner portion of select bones where blood stem cells develop into either lymphocyte or in this particular condition, myeloid cells.
T-cell acute lymphoblastic leukemia (T-ALL) is a type of acute lymphoblastic leukemia characterized by an aggressive malignant neoplasm of the bone marrow. [6] Acute lymphoblastic leukemia (ALL) is a condition, wherein immature white blood cells accumulate in the bone marrow and crowd out normal white blood cells. [7]
For some, bone marrow transplant from a matched sibling donor or a matched, unrelated donor may be favored when remission is obtained. Cord blood transplant is favored by some when a 10/10 bone marrow match is not available, and cord blood transplant may have some advantages, including a reduced incidence of graft-vs-host disease (GVHD), which ...
