CT scans can be used to check lymph nodes in the chest, though this is uncommon.Despite the use of these methods to diagnose whether or not a person has leukemia, many people have not been diagnosed because many of the symptoms are vague, non-specific, and can refer to other diseases. For this reason, the American Cancer Society estimates that at least one-fifth of the people with leukemia have not yet been diagnosed. Treatment
Most forms of leukemia are treated with pharmaceutical medication, typically combined into a multi-drug chemotherapy regimen. Some are also treated with radiation therapy. In some cases, a bone marrow transplant is effective. Acute lymphoblastic
Management of ALL is directed towards control of bone marrow and systemic (whole-body) disease. Additionally, treatment must prevent leukemic cells from spreading to other sites, particularly the central nervous system (CNS) e.g. monthly lumbar punctures. In general, ALL treatment is divided into several phases:

Induction chemotherapy to bring about bone marrow remission. For adults, standard induction plans include prednisone, vincristine, and an anthracycline drug; other drug plans may include L-asparaginase or cyclophosphamide. For children with low-risk ALL, standard therapy usually consists of three drugs (prednisone, L-asparaginase, and vincristine) for the first month of treatment. Consolidation therapy or intensification therapy to eliminate any remaining leukemia cells. There are many different approaches to consolidation, but it is typically a high-dose, multi-drug treatment that is undertaken for a few months. People with low- to average-risk ALL receive therapy with antimetabolite drugs such as methotrexate and 6-mercaptopurine (6-MP).
Undifferentiated connective tissue disease (UCTD) is a disease in which the body mistakenly attacks its own tissues. It is diagnosed when there is evidence of an existing autoimmune condition which does not meet the criteria for any specific autoimmune disease, such as systemic lupus erythematosus or scleroderma. Latent lupus and incomplete lupus are alternative terms that have been used to describe this condition.The term is sometimes used interchangeably with mixed connective tissue disease, an overlap syndrome. However, MCTD is thought by some researchers to be a clinically distinct entity and is strongly associated with the presence of high titers of ribonucleoprotein (RNP) antibodies.It is estimated that up to 25 percent of people with systemic autoimmune disease could be considered to have UCTD. Signs and symptoms
Disease presentation varies widely from patient to patient, as UCTD is by definition nonspecific. Symptoms typically include constitutional complaints that are common to connective tissue diseases such as fatigue, a general sense of feeling unwell, and fever. Other symptoms associated with UCTD include:
dry eyes
dry mouth
hair loss
joint inflammation
joint pain
oral ulcers
positive ANA test
raynauds phenomenon
sun sensitive rashClinical presentation in some people diagnosed with UCTD may show: 
a decrease in white blood cell count in the blood
anemia
abnormal nerve sensations in the extremities
inflammation of the lining of the heart and/or lungs
a decrease in platelet countLung involvement, such as nonspecific interstitial pneumonia, is a possible disease complication. Diagnosis
There is no official diagnostic criteria for UCTD. Diagnostic testing generally aims to determine whether a patient has a definite or undifferentiated connective tissue disease.
