Indian Hospital are providing comprehensive medical and surgical
care for patients with disorders of the brain, brain tumor surgery is routinely
carried out with results at par with the best centers globally. As we all know
that India is now becoming a medical hub and a growing destination for Brain
Tumor surgery. Hospitals of brain tumor surgery India provides international quality of medical healthcare services by the
best brain surgeons in India who are equipped with the most advanced medical
treatment and brain tumor healing techniques.
Brain tumor is one an abnormal mass
of tissue in which cells grows and multiply, seemingly unchecked by the
mechanisms that control normal cells. Indian Neurologists and Neurosurgeons are
supported by the most extensive neuro-diagnostic and imaging facilities
including Asia's most advanced MRI and CT technology. Along with providing
general diagnostic X-ray imaging, Hospitals of brain tumor surgery in India
offers you a magnitude of imaging services like EEG, EMG, Sensation 10 CT
Scanner, Functional MRI with Spectro-scopy, OPMI Multivision etc.
Treatment
People diagnosed with a CNS tumor generally need to seek treatment
as soon as possible. The pressure caused by a growing CNS tumor can cause
severe symptoms, including a backup of CSF and problems with blood circulation,
which can damage delicate nerves and deprive cells of nourishment.
Treating brain and spinal cord tumors can be difficult. The
blood-brain barrier, which normally serves to protect the brain and spinal cord
from damaging chemicals entering those structures, also keeps out many types of
potentially beneficial chemotherapeutic drugs. Surgery can be difficult if the
tumor is near a delicate portion of the brain or spinal cord. Radiation therapy
can damage healthy tissue. However, research in the past two decades has
improved the survival rates of patients with brain tumors. More refined
surgeries, a better understanding of what types of tumors respond to
chemotherapy, and precise delivery of radiation have resulted in a longer life
span and better quality of life for patients with brain tumors.
Surgery
Surgery is the most common type of treatment for a brain tumor
and is often the only treatment performed for a benign brain tumor. Even if the
cancer cannot be cured, its removal can relieve symptoms if it is creating
pressure on parts of the brain. There have been rapid advances in surgery for a
brain tumor, including the use of cortical mapping and enhanced imaging devices
to give surgeons more tools to plan and perform the surgery. For a tumor that
is near the speech center, it is increasingly common to perform the operation
under awake conditions. Typically, the patient is awakened once the surface of
the brain is exposed, and special electrical stimulation techniques are used to
locate the speech center and thereby avoid causing any damage while removing
the tumor.
Surgery to the brain requires the removal of part of the skull,
a procedure called a craniotomy. After the surgeon removes the tumor, the
patient's own bone will be used to cover the opening in the skull. Gliadel
wafers that deliver chemotherapeutic drugs (see below) require surgery to put
the wafers in the tumor bed site. This may be done at the same time as a
craniotomy.
In addition to removing or reducing the size of the brain tumor,
surgery can provide a tissue sample for analysis. For some tumor types, the
results of the analysis can help in showing if chemotherapy or radiation
therapy will be useful.
Radiation therapy
Radiation therapy is the use of high-energy x-rays or other
particles to kill cancer cells. Oncologists may use radiation therapy along
with surgery to slow the growth of aggressive tumors. Radiation can be directed
in the following ways:
The linear-accelerator machine provides external-beam radiation
therapy from outside the body to target the tumor within the brain; this is becoming
increasingly more precise with the addition of multileaf collimators (a device
that restricts and confines the x-ray beam to a given treatment area).
In stereotactic radiosurgery, a computer assembles images from
CT scans or MRI scans to locate the tumor and help direct the radiation. This
may involve the use of an external head device to "marry" the
patient's head/tumor location to the incoming radiosurgery beams.
Brachytherapy uses radioactive seeds implanted directly in the
tumor site; however, this treatment technique is rarely used at this time for a
brain tumor.
Radiation techniques
The following radiation techniques may be used:
Conventional radiation
therapy. The treatment location
is determined based on anatomic landmarks and x-rays. In certain situations,
such as whole brain radiation therapy for brain metastases, this technique is
appropriate. For more precise targeting, more elaborate techniques are
required. Chemotherapy may be used in conjunction with this type of radiation
therapy.
Three-dimensional
conformal radiation therapy. Based on CT and MRI images, a three-dimensional model of the
tumor and normal tissues is created on a computer. Beam size and angles are
determined that maximize tumor dose and minimize normal tissue dose.
Stereotactic
radiosurgery. Stereotactic
radiosurgery involves delivering a single, high dose of radiation directly to
the tumor and not healthy tissues. It works best for a tumor that is only in
one area of the brain and certain benign tumors, but is also used for multiple
metastatic brain tumors. There are three methods by which stereotactic
radiosurgery is performed:
- A
modified linear accelerator is a machine that creates high-energy
radiation by using electricity to form a stream of fast-moving subatomic
particles.
- A
gamma knife is another form of radiation therapy that concentrates highly
focused beams of gamma radiation on the tumor.
- A
cyber knife is a robotic device used in radiation therapy to guide
radiation to the tumor target-particularly targets in the brain, head, and
neck regions.
Fractionated
stereotactic radiation therapy. Radiation therapy is delivered with stereotactic precision but
divided into small daily fractions over several weeks using a relocatable head
frame, in contrast to the one-day radiosurgery. This technique is used for
tumors located close to eloquent or sensitive structures, such as the optic
nerves or brain stem.
Intensity modulated
radiation therapy (IMRT). Radiation therapy is delivered with greater intensity or dose to
thicker areas of the tumor and with less intensity to thinner areas of the
tumor. This is accomplished by placing tiny metal leaves in the beam to reduce
the intensity of the beam in order to customize the shape of the dose to the
shape of the tumor.
All of these more elaborate techniques are designed to achieve
greater precision and minimize the dose to the surrounding normal brain tissue.
Depending on the size and location of the tumor, the radiation oncologist may
choose any of the above radiation techniques. In certain situations, a
combination of two or more techniques is appropriate.
Very young children (younger than 5) are not usually appropriate
candidates for radiation therapy because of high risk of damage to their
developing brains.
Chemotherapy
Chemotherapy is the use of drugs to kill cancer cells. The goal
of chemotherapy can be to destroy cancer remaining after surgery, slow the
tumor's growth, or reduce symptoms.
Advanced/recurrent
brain tumors
If, in spite of initial treatment, the brain tumor does not go
into remission (the temporary or permanent disappearance of symptoms) or if it
recurs, patients can still receive care to manage the symptoms caused by the
tumor. Symptom management is always important since the symptoms of a brain
tumor can interfere with quality of life.
Since a brain tumor is so rare, it can be hard for doctors to
plan treatments unless they know what has worked in treating other patients
with a brain tumor. Clinical trials are research studies that compare the
standard treatments (the best treatments available) with newer treatments that
may be more effective. Investigating new treatments involves careful monitoring
using scientific methods and all participants are followed closely to track
progress.
Due to advances in research, new drugs are being created to
combat brain tumors. Many of these new drugs are called "small
molecules" or "molecularly targeted therapies" because they are
small in size (and can therefore be taken orally) and/or can attack a specific
molecule or target within the brain tumor cells. These new drugs are being
tested either alone or in combination with standard chemotherapy
