Brain Tumor Treatment Options in the UK

Facing a brain tumor diagnosis can be overwhelming. The good news is that the UK offers a range of advanced treatment options that are tailored to individual needs. With state-of-the-art technology and a compassionate, expert medical community, patients have access to some of the best care available. This blog provides a detailed look at the treatment options for brain tumors in the UK, helping you navigate through your choices with clarity and confidence.

1. Surgery

A. Craniotomy

A craniotomy is a common surgical procedure used to access and remove brain tumors. During the surgery, a section of the skull is temporarily removed to allow surgeons to reach the brain. This procedure is performed under general anaesthesia to ensure the patient remains unconscious and pain-free. The primary goal of a craniotomy is to remove as much of the tumor as possible while protecting vital brain structures. The extent of tumor removal depends on its size, location, and type. After the tumor is excised, the removed piece of skull is replaced and secured, and the incision is closed. Post-surgery, patients may experience temporary symptoms such as headaches, swelling, or neurological deficits, but these generally improve over time as the brain heals.

B. Endoscopic Surgery

Endoscopic surgery is a minimally invasive technique used for tumor removal through small incisions or natural body openings, such as the nose or mouth. This method involves inserting a thin, flexible tube with a camera (endoscope) and specialized surgical tools into the body. The endoscope allows the surgeon to view the tumor and surrounding areas on a monitor, facilitating precise removal. Endoscopic surgery is particularly effective for tumors located in hard-to-reach areas, such as the pituitary gland or brain ventricles. This approach usually results in less post-operative pain and a quicker recovery compared to traditional surgery. Patients may experience fewer complications and a faster return to normal activities.

C. Awake Craniotomy

An awake craniotomy is a specialized surgical technique used when tumors are located near critical brain areas responsible for essential functions like speech or movement. During the procedure, the patient is kept awake but sedated to ensure they remain comfortable. The surgeon performs the surgery while the patient is conscious, allowing them to monitor brain function in real time. This technique helps avoid damage to vital brain regions and can significantly improve functional outcomes. While the patient’s involvement during the procedure can be challenging, it provides valuable information that guides the surgical team. Recovery from an awake craniotomy is similar to that of a standard craniotomy, with additional support often required due to the patient’s active role in the surgery.

B. Intraoperative Imaging

Intraoperative imaging involves using advanced imaging technologies, such as MRI or CT scans, during brain tumor surgery to provide real-time guidance. These imaging techniques allow surgeons to visualize the tumor and surrounding brain structures throughout the operation, improving precision and reducing the risk of damaging healthy tissue. By integrating intraoperative imaging, the surgical team can make informed decisions and adjust their approach as needed to ensure complete tumor removal. This technology enhances the effectiveness of the surgery and contributes to better overall outcomes for patients. Intraoperative imaging is particularly beneficial for complex cases where accurate tumor removal is critical.

2. Radiotherapy for Brain Tumors in the UK

Radiotherapy is a critical treatment option for brain tumors, using high-energy radiation to kill cancer cells or stop their growth. It is often employed when surgery is not possible, or as an adjunct to surgery to target residual tumor cells. Here’s a detailed look at the types of radiotherapy used in the UK:

A. External Beam Radiotherapy:

The patient lies on a treatment table while a machine, such as a linear accelerator, delivers precise doses of radiation to the tumor. The patient must remain still during treatment to ensure accuracy. Advanced imaging techniques, such as CT or MRI scans, are used to map the tumor’s location, allowing for precise targeting of the radiation beams. This helps minimize damage to surrounding healthy tissue. External beam radiotherapy is effective for many types of brain tumors and can be used to treat tumors that cannot be surgically removed. The treatment plan is individualized based on the tumor's type, size, and location. Common side effects include fatigue, skin irritation at the treatment site, and temporary neurological effects such as headaches or nausea. These side effects usually diminish after treatment ends.

B. Stereotactic Radiotherapy:

Stereotactic radiotherapy is a highly precise form of radiation therapy designed to deliver high doses of radiation to a specific tumor area from multiple angles. The patient is usually immobilized using a special head frame or mask to ensure accuracy. The machine then delivers focused radiation beams to the tumor with great precision, minimizing exposure to healthy brain tissue. There are different types of stereotactic radiotherapy, including Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiotherapy (SBRT), each suited to different tumor types and locations. This approach is particularly useful for treating small tumors or residual tumor cells after surgery. It can be a standalone treatment or used in combination with other therapies.  Side effects are generally similar to those of external beam radiotherapy but can be more localized to the area being treated. Patients may experience mild swelling or irritation, which usually resolves over time.

C. Proton Beam Therapy:

Proton beam therapy is an advanced form of radiotherapy that uses protons instead of X-rays to treat tumors. Proton beams are directed at the tumor, where they deposit their maximum energy directly at the tumor site and reduce radiation exposure to surrounding healthy tissues. This is particularly beneficial for tumors located near critical brain structures. Proton beam therapy is not widely available and is typically offered at specialized centers. It is used for specific types of brain tumors or cases where traditional radiotherapy might pose a higher risk to surrounding tissues. Side effects are similar to other forms of radiotherapy but are often less severe due to the precision of proton beams. Long-term follow-up is necessary to monitor for any delayed effects.

3. Chemotherapy for Brain Tumors

Chemotherapy is a treatment that uses drugs to kill or inhibit the growth of cancer cells. It is often used in conjunction with other treatments like surgery or radiotherapy, especially for tumors that are widespread or cannot be completely removed surgically. Here’s a detailed look at the types of chemotherapy used in the UK for brain tumors:

A. Systemic Chemotherapy

Systemic chemotherapy involves using drugs that travel through the bloodstream to reach and destroy cancer cells throughout the body. Chemotherapy drugs can be administered orally (in pill form) or intravenously (through an injection or infusion). The choice of drug and method depends on the type of tumor and the patient’s overall health. Commonly used chemotherapy drugs for brain tumors include Temozolomide, which is often used for gliomas, and other agents like Carmustine and Lomustine. The drugs may be given in cycles, with periods of treatment followed by breaks to allow the body to recover. Systemic chemotherapy is typically used for tumors that are not easily removable or have spread beyond the brain. It can also be used as an adjuvant therapy to help prevent recurrence after surgery or radiotherapy.  Side effects may include nausea, vomiting, fatigue, hair loss, and an increased risk of infection due to lowered blood cell counts. Supportive medications and care are often provided to manage these effects.

B. Intrathecal Chemotherapy

Intrathecal chemotherapy involves delivering chemotherapy drugs directly into the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord. This is usually done through a lumbar puncture (spinal tap) or via an implanted reservoir. The drugs are injected into the CSF to target tumors in the central nervous system more directly. Intrathecal chemotherapy is often used for tumors that are located in or around the cerebrospinal fluid spaces or have spread to these areas, such as certain types of lymphomas or leukemias. This method allows for higher drug concentrations directly at the tumor site while minimizing systemic side effects. However, it requires careful monitoring to avoid complications such as infection or increased intracranial pressure. Possible side effects include headache, nausea, and irritation at the injection site. More severe side effects, though less common, may involve neurological symptoms or infections.

C. Targeted Chemotherapy:

Targeted chemotherapy focuses on specific molecules or pathways involved in tumor growth and survival, offering a more precise approach compared to traditional chemotherapy. Drugs used in targeted chemotherapy for brain tumors may include agents that inhibit specific proteins or enzymes involved in tumor growth. For example, Bevacizumab targets vascular endothelial growth factor (VEGF) to prevent the formation of blood vessels that supply the tumor. Targeted therapies are often used in combination with other treatments or for tumors with specific genetic mutations or molecular characteristics. They can offer fewer side effects compared to traditional chemotherapy. Side effects depend on the specific drug but can include fatigue, skin rash, or more severe reactions like bleeding or gastrointestinal issues. Regular monitoring is essential to manage these effects.

D. Targeted Therapy

Targeted therapy is a precision treatment approach that focuses on specific genetic alterations in cancer cells. Unlike traditional chemotherapy, which can affect both cancerous and healthy cells, targeted therapies aim to disrupt the growth of tumor cells based on their unique genetic characteristics. This tailored approach can lead to more effective treatments with potentially fewer side effects. Targeted therapies can be particularly beneficial for brain tumors with known genetic mutations, as they directly address the underlying causes of tumor growth, improving treatment outcomes and minimizing collateral damage to normal tissues.

E. Immunotherapy

Immunotherapy represents a promising frontier in brain tumor treatment, harnessing the body's immune system to identify and destroy cancer cells. Although still relatively new for brain tumors, this approach has demonstrated encouraging results in clinical trials. Immunotherapy works by enhancing the immune system's ability to recognize and attack tumor cells more effectively. It can be used alone or in combination with other treatments, such as surgery or radiotherapy. Ongoing research and clinical trials continue to explore the full potential of immunotherapy in treating brain tumors, offering hope for new and innovative therapeutic options.

F. Clinical Trials for Brain Tumors in the UK

Clinical trials provide access to cutting-edge treatments and experimental therapies that are not yet available through standard care. Participating in a clinical trial offers the opportunity to benefit from the latest advancements in brain tumor treatment and contribute to the development of new therapies. Trials are conducted at leading research hospitals and institutions and may include novel drugs, innovative treatment combinations, or new approaches to care. Enrolling in a clinical trial can provide hope for patients seeking alternative treatment options and may help advance the future of brain tumor management.
