SV40
virus tests? We are currently seeking
information about how to test for the presence of this virus in
lymphoma tissue and/or the blood, and will post our findings
here. Presently, our understanding is that there is no reliable
standard test for the virus, and that it will take sophisticated PCR
testing.

CRP
C-Reactive Protein
|
"C-Reactive Protein (CRP) is a
pentameric serum protein which rapidly increases in concentration at
the onset of inflammation, infection and tissue injury, and is
considered the classical acute phase reactant.
Its measurement is comparable to following erythrocyte sedimentation
rates (ESR), but CRP levels correlate more closely with the degree of
tissue damage and are more reliable and rapid in detecting changes in
disease activity.
Measurement of CRP serum levels may be helpful in the management of
inflammatory disorders such as rheumatoid arthritis, bacterial
infections, tissue injury such as myocardial infarction or burns,
neoplasia, and leukemias and lymphomas. CRP levels also can aid in the
differential diagnosis of a number of diseases" See for

Disease Direction Indications
Increasing or decreasing lab
values may help to gauge progression or response to treatment. However,
location of disease, and treatments can affect interpretation of the indicators provided here.
Therefore, it's important to consult with your doctor about questions
you may have.

Lay comment on
the importance of identify biomarkers for lymphomas
Unlike breast and prostate cancers, there are no screening tests for
the early detection of lymphomas. So the search for reliable biomarkers continues.
Perhaps investigators should look for elevated levels of multiple indicators that
together predict for lymphoma, instead of trying to find the ideal
single marker. For example, if all of the following are elevated, it may indicate you have lymphoma as reliably as elevated PSA predicts for prostate
cancer: CD25, LDH, IL-6 Beta2-microglobulin, LDH...

Serum CD25
Levels of CD25 are not typically
tested for in lymphoma patients outside of investigational settings.

Serum CD25 a receptor expressed on immune cells
This marker is not commonly tested for

| Indicator of tumor burden
"serum levels of sCD25, sCD8, sCD54, and sCD44 are roughly proportional to the burden of neoplasm (tumor), but sCD25 is clearly a more sensitive marker -- use for stage assessment is recommended.

Beta2-microglobulin
(Beta 2 M) is a
protein found on the surface of many cells, including white blood
cells.
The test helps in evaluating a person
with certain kinds of cancer affecting white blood cells including
chronic lymphocytic leukemia, and non-Hodgkin's lymphoma.
"The degree of elevation of ß2M can be related to tumor cell load, disease activity and prognosis.
Thus, ß2M may be useful as a tumor marker. In disorders such as
acute leukemia and lymphoma ...
... where there is CNS involvement
(rare), the
CSF ß2M may be elevated. This is often meaningful if measured
simultaneously with serum ß2M." ARUP's Guide
"In HD patients a significant
association was found between the level of S-beta 2M and stage of
disease (P less than 0.05) and presence of splenomegaly (P less than
0.05). No association was found between S-beta 2M level and histologic
subtypes, lymph nodes greater than 3 cm in diameter, bone marrow
involvement, and B symptoms. A significant relation was found between
S-beta 2M level and survival in HD patients with widespread disease (P
less than .025)." 2

Interleukin-6
(IL-6) is a cytokine (signal protein) that has many functions related
to immune activity, especially inflammation. It is also described as a
biological response modifier - a substance that can improve the body's response to infection and
disease.
Higher than normal levels of IL-6 is
often associated with the progression of some lymphomas.

SEARCH: LDH
AND Lymphoma | PubMed
Background wikipedia.org
Lactate Dehydrogenase (LDH) or (LD) is an enzyme that
is expressed at higher levels when lymphocytes are dividing or, more
commonly, when cells are distressed and damaged, particularly red
blood cells.
Elevating LDH is an indirect indication of disease progression.
Sharp increases can indicate transformation. " Drugs that
can increase LDH measurements include: anesthetics, aspirin,
clofibrate, fluorides, mithramycin, narcotics, and procainamide."
- MedlinePlus [1]
NOTE: Your doctor will look at LDH in the context of
clinical symptoms and other lab results. Normal variability of results
can be 20 points or more. Treatments can also affect LDH levels
temporarily. Tumor lysis (death) resulting from treatment might raise
LDH initially - in that context uric acid and magnesium levels will
also increase as well.

Testing T-cell
counts and function can help to measure immune competence. These tests
are not commonly ordered for NHL pts, but they might provide useful
information for doctors when considering immune-based therapies
for their patients.
| T-Cell Subset Panel (CD4 Count) path.upmc.edu
"Performed on peripheral blood. It may be identified as
T-lymphocyte test, T-Cell Subsets, T and B Cells, CD4/CD8 ratio,
immunodeficiency panel, or by other synonyms. It includes a total
or pan-T-cell antibody, a total or pan B cell antibody, a T Helper
cell (CD4) antibody, a T Suppressor cell (CD8) antibody, and two
natural killer cell associated antibodies. No functional tests are
performed. Results include both relative and absolute values for
each cell type as well as the T helper/suppressor ratio. The test
is performed according to CDC guidelines."
