Delving Into The Intricacies Of Brain Cancer Treatments

Brain cancer treatments are generally complex with majority of the treatment plans involving many consultant doctors. The panel of doctors would comprise of neurosurgeons (experts in the field of brain and nervous system), oncologists, radiation oncologists (those doctors conducting radiation therapy) and the General practitioner. The team would additionally involve a dietician, a physiotherapist and possibly other experts.

The treatment procedure varies extensively on the basis of the site of the tumour, its extent and form, the individual’s age and any other medical issues that one might be having.

The most prevalent brain cancer treatments procedure involve surgery, radiation therapy and chemotherapy. In few cases, a merger of more than one of them could be employed.

Surgery

Majority of the individuals having a brain tumor would require undergoing surgery.

• The objective of the surgery is for corroborating the finding of the anomaly on the brain scan is actually a tumour and for its removal in case confirmed. In situations where the tumour could not be taken out, a tumour sample would be taken by the surgeon for identification of its form.
• In few circumstances, most often in the case of benign tumours, symptoms could totally be treated by surgical excision of the tumour. The neurosurgeon would try removing the tumour when achievable.
• Stereotactic surgery is a novel ‘knife-less’ system for annihilating a brain tumour with no requirement to open the skull. A CT or MRI scan is employed for accurately pinpointing the position of the tumour in the brain. High-power radiation rays are focussed on the tumour from varying angles that aid in obliterating the tumour. This method is occasionally known as ‘gamma knife’.
• The benefits of knife-less treatments are that they have lesser associated complications and the recuperative period is also briefer.

The person might require undergoing many brain cancer treatments and procedures prior to surgery.

• A steroid drug like dexamethasone could be administered for allaying the swelling.
• Anticonvulsant medications like carbamazepine (Tegretol) could be given for relieving or preventing the seizures.
• In case there is excessive build-up of CSF or cerebrospinal fluid around the brain, then a fine plastic tube known as stent would need to be placed for draining out the fluid accumulation. One tip of the shunt would be placed in the cavity that has fluid accumulation whereas there would be threading of the other end of the shunt underneath the skin’s layer to another part of the body. The fluid drainage occurs from the brain to a location from where there is easy elimination of the fluid.

Radiation Therapy (Radiotherapy)

Radiation therapy is the usage of high-power energy beams for destroying the tumour cells and hampering their growth and multiplication.

• Radiation therapy is occasionally employed for those individuals that could not go through surgery. In other circumstances, it is utilised following surgery for destroying any remnant tumour cells.
• Radiation therapy is a localized form of therapy wherein it is observed to affect solely the targeted cells and causes no damage to the cells located in other parts of the body or even those cells in another location in the brain.
• Radiation therapy could be offered in either of the two ways:
  • External Radiation
    It utilises high-power energy radiation rays that target the tumour. The ray passes through the skin, skull, normal tissue of the brain and other kinds of tissues to be able to reach the site of the tumour. The treatments are normally administered on weekdays lasting for 4-6 weeks, each of the session requiring just few minutes.
  • Internal or implant radiation
    It employs a small radioactive pod which is placed within the tumour. The emission of radiation from the pod helps in killing the tumour. The radioactivity strength of the pod depletes gradually with every passing day; the quantity of which is meticulously computed for running out when the most favourable dosage has been administered. Hospitalization for some days would be necessary during the course of this treatment.

Chemotherapy

Chemotherapy is the deployment of potent cancer-combatant drugs given either as a single drug or a blend via either the oral route or intravenously. Few of the medications are offered via the shunt placed for drainage of fluid build-up in the brain.

• Chemotherapy is normally administered in cycles wherein each cycle lasting for few weeks comprises of a brief time of exhaustive treatment ensued by a time period of rest and recuperation.
• Majority of the treatments are planned so that 2-4 cycles are concluded after which a break is given for checking the manner in which the tumour has shown response to the treatment.
• Chemotherapy side effects are well identified and several individuals find it quite unendurable. The side effects involve feeling nauseous, vomiting, oral sores, depleted appetite and hair loss. Few of the side effects could be allayed or reduced with medication.

Follow-up

With the detection of the brain tumour, it is imperative to be vigilant regarding following one’s appointments with the doctors and the general practitioner. Generally, those having brain cancer are at heightened risk of developing further medical problems and probably face a relapse or deterioration of their symptoms.

Survival Rates

The key factors influencing survival appears to be the form of the cancer, its site, whether surgical removal or reduction is performed, the age of the person, and other medically linked problems.

• The long-standing survival rate (above 5 years) for individuals having primary brain cancer is less than ten percent, in spite of belligerent surgery, radiation and chemotherapy. However such treatments do tend to protract survival in the short term and conceivably enhancing quality of life while the individual is still animate.
• Majority of the individuals having metastatic brain cancers face fatality due to their primary cancer instead of from the brain lesions. In such a situation, radiation and chemotherapy moderately raises life expectancy.
• Those having seizures usually do weakly over the subsequent 6 months.

In spite of the likelihood of long-standing survival appearing dreary, these chances are undoubtedly better with treatment in comparison to without treatment.
