Epithelial mesothelioma cells have a clear structure and
specific nuclei are visible. This is the most common alternative to this type
of cancer, mesothelioma, which represents about 60 percent of all cases
pathological.
This type of mesothelioma development of malignant cells
when placed on any of the epithelial lining. When examined under a microscope
and these types of mesothelioma cells are of uniform size and shape similar to
normal healthy epithelial cells.
Mesothelioma cells with epithelial cells is also a strong
resemblance to adenocarcinoma, which is also associated with lung tissue. It
should also be patients who have been diagnosed with adenocarcinoma studied for
the diagnosis of mesothelioma.
Epithelial mesothelioma occurs most often in adults and
usually float on the surface between the ages of 50 and 70 years with 70-80% of
cases in men. In more than 90% of cases, directly related to the occurrence of
mesothelioma to a history of exposure to asbestos
professional. Available
information shows that mesothelioma can occur as a result of both exposure and
semi-professional "environment" was unprofessional. And is usually
diagnosed in individuals age 25 to 40 exposed to asbestos and children. There
were also cases of mesothelioma idiopathic that occur without exposure to
asbestos. Those with a spontaneous rate of about one per million of all cases.
Mesothelioma malignant epithelial term describes a specific
type of cell that can be involved in your case. If epithelial mesothelioma and
also called "epithelioid" cells may be found to have the best
developments and be more responsive to treatment compared with patients who
suffer from other cell types under the rates of response to treatment to have.
Understand the characteristics of epithelioid mesothelioma and will be and how
they are diagnosed with the disease and find out what treatments are available
that help you understand how they affect the diagnostic cell types infected by
the patient.
When inhaled asbestos fibers once they settle in the lung
tissue and settle in it indefinitely. And is associated with mesothelioma is
difficult to asbestos amphibole crystal which consists of the hard needle-like
fibers, which literally bore through the lung tissue over time, causing chronic
inflammation that ultimately lead to malignancy. In the latency period of
mesothelioma can be between 5 to 7 years and we are symptoms similar to those
of other respiratory diseases and that is why in the diagnosis of mesothelioma
is historically very difficult to do.
Because of epithelial malignant mesothelioma accounts for
50% to 70% of all cases have been carried out much research on this type of
cells. Although the methods of treatment usually does not differ from cell type
to another may find out which type is dictated by the clinical trials available
to you. Some doctors consider the type of cells through their research in an
attempt to increase understanding of patient response rates to treatment.
Classified types of mesothelioma cells by the appearance of
the cells that form of cancer. Epithelial cells are part of the skin or layers
of cells covering the inner surfaces of the body. Small cells look like tube
structures. When epithelial cells become cancerous so-called epithelioid cells.
Mesothelioma epithelioid most commonly occur in malignant pleural mesothelioma.
How is the diagnosis of epithelioid tumor
Are not recognized epithelioid mesothelioma easily through
microscopic examination of cells. To determine which type at the present time
and at any stage of a thoracoscopy, or any other type of surgical biopsy needs
to be performed. Biopsies offer doctors a way to examine cells and tissues
associated with the tumor. During a biopsy, a sample is extracted from the
tumor for further evaluation.
Can be confused with glandular epithelioid mesothelioma, or
a type of cancer that grows in the cells in internal organs such as lung and
breast. Mesothelioma has a subspecies glandular epithelial cells, similar to
adenocarcinoma in the lungs. It may be difficult to diagnose these two
conditions, a simple and biopsies of the pleura are often not effective,
surgical biopsy may be necessary.
The unveiling of the specific type of cells involved in your
case in the pathology report. If you were not the type of cell has been said so
far, just ask your doctor and consider the request for a copy of the pathology
report for your records.
Epithelioid tumor subtypes
When epithelial cells become cancerous mesothelioma can be
classified as epithelioid or sarcomatoid or biphasic if the cells of both
epithelioid and sarcomatoid the present time. And is determined by both types
of physical characteristics in terms of size, shape and structure of the cell.
Perhaps even the epithelial cells can be classified as well as one of the
following subtypes:
• Deciduoid
• Tubulopapillary
• glandular
• histiocytoid
• adenoid cystic
• sacculation minute
• Macrocystic
• ring signature
• a single file
• Diffuse - NOS
• Glomeruloid
• small cell
• poorly differentiated
• the positive mucin
• Gaucher-like cells
• well differentiated papillary
• on-site
How epithelial cells affects the treatment and diagnosis
Treatment of epithelial mesothelioma treatments, similar to
other types of cells. In fact, mesothelioma treatment often depends on the
stage of the cancer and the location of the cancer rather than the specific
type of cell. However, since the epithelioid cells respond better to treatment can be considered patient epithelioid mesothelioma to develop a more aggressive
treatment plan that patients who suffer from other cell types. Some treatments
are the most common is through surgery, chemotherapy and radiation therapy.
The presence of epithelial cells is normally produced in a
better position compared with the diagnosis of sarcoma subtypes, and biphasic.
Average survival time of patients with epithelial mesothelioma of about one
year after diagnosis. Improve the prognosis is not so much, and usually within
a few months in most cases, but may reach more than several months or years if
diagnosed at an early stage and received the appropriate treatments.
