Radiation Therapy For Brain Cancer - Can It Have Side Effects?

Radiation therapy is used for destroying the brain tumor cells, and relieves the symptoms of discomfort and pain caused by the tumor. Radiation is usually used after biopsy or resection of the tumor. This is done to destroy the microscopic cells of the tumor which have been left behind. Sometimes this is also an option for unresectable brain tumors or the metastatic tumors which spread to the brain from other parts of the body.

The radiation therapy is planned on several factors like the size and type of the tumor and the extent to which it has spread. Usually external beam radiation is used for the brain cancer and the area radiated involves the tumor and the surrounding area. In case of a metastatic brain cancer the radiation is given to the entire brain. People who have lung cancer receive radiation in the brain as a preventive therapy in order to stop the metastatic cancer from developing.

Side effects of brain cancer radiation
Depending on the site, dose, and other factors the radiation therapy when given to the brain might cause side effects. Hair loss, fatigue, edema, skin irritations are a few common side effects of brain tumor radiation. In some cases some people might develop swelling of the ankle, foot, calf and blood clots in the leg.


What is radiation therapy?
Radiation therapy is basically the use of targeted energy like X-ray to kill the cancer cells, or shrink them or change the symptoms related to cancer. This therapy might be used as:

 

  1. Primary treatment for the destruction of the cancer cells
  2. In combination with other ongoing treatments to inhibit the growth of the cancer cells
  3. Prior to another treatment to shrink the cancer cells
  4. Post some treatment to stop the growth of any cancer cells that have been left behind
  5. To relieve cancer symptoms

Types of radiation
Some of the radiation methods commonly used are:

  1. External beam radiation therapy: In this the radiation is directed from outside the body on the cancerous cells in the body. Some examples of this are IMRT, TomoTherapy, stereotactic radiosurgery, 3D conformal radiation therapy and IGRT.
  2. Internal radiation therapy: Examples of this are high-dose rate brachytherapy.

Brain Cancer - How Radiosurgery Can Be Of Help?

Brain cancer is a disease of the brain in which cancer cells (malignant cells) arise in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumor) that interferes with brain functions such as muscle control, sensation, memory, and other normal body functions. Tumors composed of cancer cells are called malignant tumors, and those composed of mainly non-cancerous cells are called benign tumors. Cancer cells that develop from brain tissue are called primary brain tumors while tumors that spread from other body sites to the brain are termed metastatic or secondary brain tumors.

Prologue:

  1. Brain cancer is actually the abnormal growth and uncontrolled growth of the cancer cells in the brain,that forms a tumor in the brain.Tumours can be either benign or malignant.

  2. Benign brain tumours are abnormal collections of cells that reproduce slowly and usually remain separate from the surrounding normal brain.

  3. Malignant tumours reproduce and grow quickly. Their borders are hard to distinguish from the normal brain around them.

Symptoms:

There are few early symptoms of brain cancer, but as the tumour grows within the confines of the skull, it causes increased intracranial pressure and exerts pressure on the brain, causing signs to develop.

Brain cancer symptoms and signs are varied and depend on the area of the brain involved, but can include:

  1. Headaches.

  2. Seizures.

  3. Nausea and vomiting, which, CANSA reports, may be worse in the morning or after a sudden position change.

  4. Difficulty walking or clumsiness.

  5. Vision changes.

  6. Changes in alertness.

  7. Behavioural impairment.

Causes:

Brain cancer occurs when there is an uncontrolled growth of cancer cells in the brain that form a malignant brain tumor. The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.

What are the risk factors for brain cancer?

  1. Certain inherited conditions, including neurofibromatosis, Von Hippel-Lindau syndrome, Li-Fraumeni syndrome, and Turcot syndrome

  2. Personal history of cancer or family history of brain cancer

  3. Impaired immune system

  4. Radiation therapy of the head

Treatments Options:

Treatment

Surgery is the main form of treatment for brain tumors that lie within the membranes covering the brain or in parts of the brain that can be removed without damaging critical neurological functions. The goal is to remove the entire tumor, whenever possible, as a tumor may recur if any tumor cells are left behind. Radiation therapy and chemotherapy are generally used as secondary treatment for tumors that cannot be cured through surgery alone.

Stereotactic radiosurgery

Stereotactic radiosurgery is a treatment option that delivers a high concentration of radiation directly to the tumor in order to stop its growth, while delivering only a minimal dose of radiation to the surrounding tissue. Unlike conventional surgery, stereotactic radiosurgery does not require making an incision to remove the tumor. It can be especially effective in patients with many small metastatic brain tumors.

Brain Surgery - Can It Cause Amnesia?

Often it has been observed in patients undergoing a brain surgery that their memory gets affected. The memory can sometimes be affected either by the tumor growing inside the brain or by the surgery for the removal of that tumor. Rather than the long-term memory, in the majority of the brain surgery cases, it is the short term memory that gets affected more noticeably. Further, sometimes, people have difficulties in making new memories after the brain surgery along with retrieving the old ones. Continue reading to know more about brain surgery and amnesia.

How is brain surgery connected to amnesia?
The presence of a tumor in the brain can affect one's memory in two different ways. Though not everyone suffers from it, there is a possibility that the treatment or the surgery often leads to memory difficulties and sometimes it's the location of the tumor in the brain that causes the memory damage. Sometimes, even radiations or chemotherapy sessions can also be responsible for amnesia. One must know that having a brain tumor or opting for a brain surgery doesn’t necessarily cause memory loss or amnesia for everyone. And those patients who do suffer from this, both the severity and symptoms of the memory loss vary from one to another.

Probable memory difficulties
Memory difficulties, also commonly referred to as amnesia, can be two different types, retrograde amnesia, and anterograde amnesia, irrespective of whether it is the result of the treatment or the location of the tumor. In case of retrograde amnesia, the memory loss occurs before undergoing a brain surgery, or sometimes even before developing the brain tumor. However, those who suffer from anterograde amnesia face difficulties in remembering their previous memories after the brain surgery is performed.


Coping with amnesia
Once the type of memory loss one is suffering from is identified, there are various ways and strategies to cope with amnesia, suggested by the doctors. Taking good care of one’s self, having the necessary amount of sleep along with a healthy diet helps one improve his or her capacity of recalling the forgotten memories in many cases.

 

Further, by adopting simple measures like maintaining a diary, following a routine and organizing one's medications with reminder notes can also help an amnesia patient in coping with the normal life situations. Minimizing the distractions and focusing on a single thing at a time can also be helpful in not only coping with it but also in improving the memory.

In case one displays signs of having a memory problem after a brain surgery, he or she should be immediately taken to a clinical psychologist or a neuropsychologist. Because it is with the help of this medical professional that severity of the amnesia that the person is suffering from and which part of memory has been affected can be determined, and the right ways of coping with the issue can be suggested. In case you have a concern or query you can always consult an expert & get answers to your questions!

Types & Treatment for Brain Tumor

Types & Treatment for Brain Tumor

Grading of brain cancer is entirely different as compared to the staging of other cancers in the body. Cancer in the breast, lung, colon etc. are staged depending on the possible spread, location of a tumor and lymph node involvement etc. However, brain tumors are graded based on the aggressiveness of the tumor cells under a microscope. The resect ability and the grade of the tumor cells guide a doctor on the treatment decisions. The decision of a brain surgery depends on factors such as the location, spread of a tumour and the general health of the patient.

Types of Brain Tumor Grading:

Grade 1 tumor- These sets of tumors are medically known as the juvenile pilocytic astrocytoma and subependymoma. They are slow growing and non-invasive. There is a likelihood of the patient getting cured with surgery.
Grade 2 tumor- These are brain tumors that do not possess dead cells as part of the tumour. But, they do portray a lot of abnormal cells. Tumors of this type can be categorized under oligodendroglioma, astrocytoma, and ependymoma.
Grade 3 tumor- Tumors of this type are graded based on the cell type of the cancer cells. For instance, an anaplastic astrocytoma is a grade 3 tumor that has no dead cells but possesses dividing cells. In contrast, anaplastic ependymoma and anaplastic oligodendroglioma are grade 3 tumor cells that have dead cells in them.
Grade 4 tumor- Tumors of this type are referred to as glioblastoma. The tumor cells are actively dividing, the growth of blood vessels is witnessed and areas of dead tissue keep expanding.

Treatment options:
Surgery-
If the location of a brain tumor is such that it is accessible to a surgeon, the latter goes ahead and removes most of the tumor if not the whole. If, however, the brain tumor cells are placed very near to the surrounding very sensitive brain tissues, a doctor might remove a small portion of the tumor to curb its growth.
Radiation Therapy- This mode of treatment uses high energy X-ray beams to kill targeted cells of the brain. External beam radiation usually targets a small area of the brain. A whole brain radiation, on the other hand, is usually employed when a tumor has spread to most parts of the brain. Radiotherapy is now so evolved that it is highly targeted to tutor cells that kills cancer and spares normal brain.
Chemotherapy- Chemotherapy employs drugs to kill cancer cells. Chemotherapy can either be taken in the form of an IV or in the form of pills. The dosage of chemotherapy is decided based on the concentration of cancer cells, spread frequency, platelet count of the patient etc. The most common chemotherapy drug that is prescribed by doctors to fight cancer cells is temozolomide.

Brain Cancer - Know About Its Stages And Treatments!

Like most other organs of the human body, the brain too is susceptible to cancer. Brain cancer is typically the result of abnormal growth of primary brain cells or the spreading of cancer cells that originated in another organ of the body. This is known as secondary or metastatic brain cancer. Depending on the stage it is diagnosed in, brain cancer can be cured. Let’s take a closer look at primary brain cancer.

Primary brain cancer or the development of tumours in the brain is fairly uncommon. However, they may attack children and adults alike. There are many different types of brain tumours. Their names depend on the part of the brain affected or the type of cell they originate from. The most common types of brain tumors are meningiomas, gliomas, pituitary adenomas, primary CNS lymphomas, vestibular schwannomas and medulloblastomas. Each of these tumors grows at a different rate and causes different symptoms. However, they can all be graded on the same stages.

Stage 1
In this stage, the cell growth is usually very slow. These cells look very similar to normal brain cells and the tissue is benign.

Stage 2
When cancer reaches this stage, the cells begin to grow at a faster pace and look a little different from normal brain cells. The tissue also turns malignant at this point.

Stage 3
The abnormal cells or tumor begins to grow actively and take on a completely different look as compared to normal brain cells. These calls may also be termed as anaplastic.

Stage 4
This is the most aggressive stage of brain cancer. At this stage, the cells begin to grow at a very fast rate.

Treatment for brain cancer depends on a number of factors including the size of the tumor, cancer stage, patient’s overall health, age and any other medical issues that may be present. Brain cancer can be treated with drugs, surgery, radiation and chemotherapy. Two or more of these forms of treatment are usually used together for faster and better results.

Whenever possible, a doctor will try to remove the tumor surgically. This may be preceded by drugs to prevent seizures and relieve swelling in the brain. Patients who cannot undergo surgery may be given radiation instead. This form of therapy uses high energy rays to kill the cancer cells. Radiation may also be used after surgery to kill any abnormal cells that could not be removed surgically. Radiation for brain cancer may be given externally or internally. Chemotherapy can also be used to treat brain cancer. This involves delivering medication orally or intravenously to kill the tumors. Each cycle of chemotherapy usually lasts a few weeks and is followed by a rest period. The results of chemotherapy are usually visible after 2 or 4 cycles.

Recovering From Brain Surgery - Tips To Help You Get Better Fast!

Undergoing Brain Surgery can be a very traumatic experience, and it is common for many patients recovering from brain surgery to face depression, spells of dizziness, confusion and weakness post the surgery. It can be very critical that family members and friends talk to the patient and be empathetic towards them.

It takes approximately 12-18 months for the brain to heal after a brain surgery and slowly and gradually the patient will regain all his normal functions and get back to his daily routine. However in that time they need the complete support and understanding of their families, as well may need help from therapists. This will help the patient in gaining back their independence as well as confidence in their abilities.

Here are some tips that will help you deal with a patient recovering from Brain Surgery:

  1. After brain surgery, a person may feel disoriented and have some speech or understanding disability for a while. Family members and friends are advised to take pause when talking to the patient, so that he/she can easily understand the conversation. Speaking slowly is not recommended, as patients may recognize it and have an emotional outburst or feel hurt.

  2. Caretakers and family members should also keep reminding the conversation topic at different points to the patient, so that it is easier for them to participate in the conversation.

  3. Family members should also not react adversely in case of emotional outbursts, instead show love and patience to a person recovering from brain surgery.

  4. Caregivers should make sure that the person recovering from brain surgery gets enough sleep and rest to recuperate.

  5. People interacting with someone recovering from brain surgery should understand that the person's ability to learn and remember will improve daily, and any lapses in attention by the patient are not caused by any act of obstinacy. Your care and understanding will be essential for a person to recover.

  6. Family members should also make sure just to give enough care and not smother the brain surgery survivor. It is essential for them to regain their confidence and a sense of competence.

Family members should take the patient for a neuropsychological examination--after treatment, 6 months later, and a year later to see if they are recovering properly. Caregivers should watch out for emotional outbursts, like rage, uncontrollable laughter, withdrawal and depression. In case of such symptoms it is advisable to take the patient for a check up with medical practitioner.

CT Angiography Of Brain - Know Its Benefits!

CT Angiography Of Brain - Know Its Benefits!

A brain computed tomography angiography (CTA) is a specialized neurologic CT scan, and it involves fast CT imaging while simultaneously injecting IV contrast into a vein in the arm. This procedure allows visualization of the specific vascular anatomy of the organs in the body. It can also be used to evaluate vessels or plan a surgery. Mostly it is used to identify a small aneurysm or arteriovenous malformation (abnormal communications between blood vessels) inside the brain.

  • A patient can expect the following things during the brain CTA examination:
  • The patient is asked to lie on the examination table.
  • If contrast is used, an automatic injection pump connected intravenously will release the contrast material at a controlled rate.
  • Although the movement of the table occurs slowly at first, it gains rapid momentum when the actual CTA is performed.
  • The patient may be asked to hold his/her breath during the scanning.
  • Any motion in the form of breathing or body movements can lead to artifacts on the images.

The entire CTA exam may be completed within a few seconds. However, the patient’s actual time in the room may be long. This delay can occur as the technologist takes his/her time to position the patient on the table, check or place an IV line, do preliminary imaging to verify the beginning and end points of the exam, and set up the scan and contrast injection settings based on the part of the body being imaged.

Benefits of brain CTA include the following:

  • The need for surgery may be eliminated by angiography; however if surgery remains necessary, it can be performed with much accuracy because of brain CTA findings. As the CTA is able to detect the obstruction of blood vessels, it allows for potentially corrective therapy.
  • The CTA may give precise anatomic detail than a magnetic resonance imaging (MRI), particularly in cases of small blood vessels.
  • The CTA is faster, noninvasive, and has lesser complications than catheter angiography, which involves placing a catheter (plastic tube), (usually at the groin) into the patients’ major blood vessels and injecting a contrast material along with probable sedation or general anesthesia.
  • The CTA examination costs lesser than catheter angiography.No radiation remains in a patient's body after a CTA examination.

Risk factors for brain CTA

A small chance of cancer from excessive exposure to radiation History of allergy to X-ray contrast material Risk for kidney failure, as the contrast material could potentially further damage the kidney function in patients with pre-existing kidney disease
