| When
a patient may have cancer, physicians confront
a chain of pressing questions: What type of cancer
is it? Which treatments are most likely to work?
Finding the answers to these questions quickly
and accurately is vital.
By providing this information, Center for Medical
Genetics can help the right treatment to start
now. We enable both patients and payers to benefit
from more effective — and cost-effective — cancer
management.
We provide a comprehensive report to help cancer
specialists correctly diagnose hematologic specimens,
establish prognosis in many cancers, including
breast and determine optimal treatment in an
increasing number of cancers.
Hematopoietic Malignancies
Leukemia, lymphoma and myeloma are hematopoietic or blood borne cancers that
originate in the bone marrow (leukemia and myeloma) or in lymphatic tissues
(lymphoma). They are related cancers because they involve the uncontrolled
growth of cells with similar functions and origins. The diseases result from
an acquired, not inherited, genetic injury to the DNA of a single cell, that
becomes abnormal (malignant) and multiplies continuously. The accumulation
of malignant cells interferes with the body's production of healthy blood
cells and makes the body unable to protect itself against infections.
These are a diverse group of cancers, with the
distinctions between types based on the characteristics
of the cancerous cells. Each group is diagnosed
and treated differently, and each has prognostic
factors that categorize it as more or less favorable.
Hematopoietic malignancies constitute an ideal
model for demonstrating the value and necessity
of applying multiple cutting-edge technologies
for their diagnosis, prognosis and treatment.
Immunohistochemistry and/or Flow Cytometry
Morphology is still the “gold standard” for many hematologic diagnoses and
continues to serve as the first step in evaluation to determine which of the
more complex diagnostic tools should be used for further investigation. Flow
cytometry is a rapid and flexible way to measure the properties of individual
cells. Some of the applications in which Center for Medical Genetics utilizes
these tools are:
- Lymphoma vs. reactive hyperplasia
- Non-Hodgkin's lymphomas (NHL)
- Anaplastic large cell lymphoma (ALCL)
- B-cell lymphoma
- Follicular lymphoma (FL)
- Mantle cell lymphoma (MCL)
- Marginal zone lymphoma (MZL)
- T-cell lymphoma and leukemia
- Acute myelogenous leukemia (AML)
- Acute lymphoblastic leukemia (ALL)
|
- Myeloproliferative disorders
- Chronic myelogenous leukemia (CML)
- Myelodysplastic syndromes (MDS)
- Chronic lymphoproliferative disorders
- Chronic lymphocytic leukemia (CLL)
- Hairy cell leukemia (HCL)
- Plasma cell dyscrasias
- Hodgkin's disease
- Paroxysmal nocturnal hemoglobinuria
(PNH)

Cytogenetics
Cytogenetics is the study of normal and abnormal chromosomes. The study includes
examination of chromosome structure, the relationship between genotype and
phenotype, and the cause of chromosome abnormalities. Some of the applications
in which Center for Medical Genetics utilizes these tools are:
- Myeloproliferative disorders
- MDS
- ALL
- AML
- CML
|
- Lymphoproliferative disorders
- CLL
- Lymphomas
- Solid tumors
|
Fluorescence In Situ Hybridization (FISH)
FISH is a rapid technique for the evaluation of both dividing and non-dividing
cells. It is a valuable tool in disease monitoring and may be performed on
peripheral blood. Some of the applications in which Center for Medical Genetics
utilizes these tools are:
- Minimal residual disease detection
- Myeloproliferative disorders (CML,
others)
- Acute lymphoblastic leukemia (ALL)
- Acute myelogenous leukemia (AML)
- Plasma cell dyscrasias (PCD)
|
- Lymphoproliferative disorders
- Chronic lymphocytic leukemia (CLL)
- Solid tumors
|
Molecular Pathology
PCR is a process for amplifying one or more specific DNA sequences contained
in nucleic acids and is useful in cases where only small amounts of sample
are available. Some of the applications in which Center for Medical Genetics
utilizes these tools are:
|
Polymerase Chain Reaction (PCR)
- BCR/ABL gene rearrangements
- PML/RARA gene rearrangements
- BCL-1/IgH gene rearrangements
- BCL-2/IgH gene rearrangements
- B-cell gene rearrangements
- T-cell receptor gene rearrangements
