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 new method developed using data from the M.D. Anderson Cancer Center found that a haemoglobin level of <12g/dL, total circulating lymphocyte count of >2.5 x 10 9 /L, >0% immature myeloid cells, >10% bone marrow blasts causes a reduced overall survival. This data allows cases of CMML to be stratified into low, intermediate-1, intermediate-2 ...
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]

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.
A subset of solitary plasmacytomas, termed solitary plasmacytoma with minimal bone marrow involvement, has the same criteria for diagnosis as solitary plasmacytoma except that bone marrow examination shows an increase in plasma cells from a normal value of ~0% to 1.5% to >~1.6% but less than 10% of total nucleated cells. While its presentations ...
Chronic lymphocytic leukemia (CLL) is a type of cancer that affects the blood and bone marrow. [8] [9] In CLL, the bone marrow makes too many lymphocytes, which are a type of white blood cell. [8] [9] In patients with CLL, B cell lymphocytes can begin to collect in their blood, spleen, lymph nodes, and bone marrow.
