As many as 16% of myeloma patients secrete only light chains, which may not be identified on serum immunofixation.3,6,7,10,14,15 In general, a low kappa-lambda ratio (< 0.26) indicates the overproduction of lambda light chains, and a high ratio (> 1.65) indicates the overproduction of kappa light chains. The result is high potassium, phosphorus, uric acid, and blood urea nitrogen levels. Importantly, patients with unexplained bone pain (mostly in long bones, ribs, and spine, whereas joints are not typically involved) and a normal skeletal survey should undergo advanced imaging (whole-body magnetic resonance imaging or whole-body positron emission tomography and computed tomography) to detect bone lesions otherwise missed on plain radiography.28,29. An M protein appears as a narrow spike on the agarose gel and should be distinguished from the broad band seen in polyclonal gammopathies associated with cirrhosis and chronic infectious and inflammatory conditions, among others.12 A major disadvantage of serum protein electrophoresis is that it cannot detect an M protein in very low concentrations or determine its identity. The hematologist may also order blood tests such as a complete blood count. Copyright 2023 The Cleveland Clinic Foundation.

Based on the International Myeloma Working Group consensus, a formal diagnosis of MGUS is established when a serum M protein is detected and measured at a concentration less than 3 g/dL on serum protein electrophoresis along with less than 10% clonal plasma cells in the bone marrow.16,14,18,19 Nevertheless, bone marrow biopsy can be omitted in certain patients as discussed below. A study evaluated the predictive ability of the combined SMI and PNI to assess survival in advanced gastric cancer patients. A bone marrow specimen is not required for diagnosis of chronic lymphocytic leukemia, but can be obtained to determine the extent of marrow involvement for prognosis.17 The diagnosis of chronic myelogenous leukemia requires cytogenetic or molecular testing of the bone marrow or peripheral blood for a specific abnormality called the Philadelphia chromosome, or the BCR-ABL1 fusion gene.16 In chronic myelogenous leukemia, a reciprocal translocation between chromosomes 9 and 22 results in the formation of the BCR-ABL1 fusion gene that disrupts the normal cell regulatory processes in the bone marrow. Please check and try again, Please enter recipient's Without removing the cause, it is difficult to treat the condition. An M protein is typically an incidental finding when a patient is being assessed for any of a number of presenting symptoms or conditions. Curative treatment consists of hematopoietic stem cell transplantation, which is usually reserved for younger patients or when the disease does not respond to tyrosine kinase inhibitors.20, Tumor lysis syndrome occurs as a result of chemotherapy (or rarely, spontaneously) when widespread cellular destruction releases intracellular contents into the bloodstream. In patients with leukemia, fever with neutropenia (fewer than 500 neutrophils per L [0.5 10. Severe anemia can cause temporary losses of consciousness, shortness of breath, and low tolerance to exercise. Common causes of macrocytosis include: Vitamin B-12 deficiency. A recent study highlighted the importance of risk stratification in reducing the costs associated with an overzealous diagnostic workup of patients with low-risk MGUS.30 These savings are in addition to a reduction in patient anticipation and anxiety that universally occur before invasive procedures. Aplastic anemia is a type of anemia where the body stops producing blood cells that are important for vital functions that include: Managing aplastic anemia relies on determining the underlying cause. Copyright 2019 The Cleveland Clinic Foundation. Patients with MGUS can be risk-stratified on the basis of the amount and type of their monoclonal protein as well as whether they have an abnormal light-chain ratio. Low white blood cell count When to see a doctor - Mayo Clinic For this reason, a doctor may refer a person to a hematologist for diagnosis if they think the person may have a form of aplastic anemia or if they cannot identify the cause of anemia. There are different methods of assessing anemia depending on the type. Patients with intermediate-and high-risk MGUS could be referred for bone marrow biopsy before assessment by a hematologist.

Once an M protein is found, immunoglobulin quantification, a complete blood cell count, and serum creatinine and calcium measurements are also recommended to look for anemia, renal failure, and hypercalcemia, which can be associated with symptomatic myeloma.3,5,6,1822. Referral to a hematologist is warranted for patients with intermediate- and high-risk MGUS, patients with abnormal serum free light-chain ratios, and those who show evidence of malignant progression. Acute lymphoblastic leukemia occurs more often in children, whereas the other subtypes are more common in adults. The imaging tests are especially effective in helping to discern if the cancer has spread beyond the lymph nodes to organs such as the lungs and spleen.

Practically all medical conditions involve hematology to some degree, given that blood tests are commonly used to diagnose or monitor them. An abnormal light-chain ratio, especially if skewed toward lambda should trigger an investigation for light-chain amyloidosis.10, Abnormal light chains may infiltrate any organ or tissue, but of greatest concern is infiltration of the myocardium with ensuing heart failure manifestations. If your primary care physician has recommended that you see a hematologist, it may be because you are at risk for a condition involving your red or white blood cells, platelets, blood vessels,.
