Navigating Brain Tumour Recurrence: Surgical and Non-Surgical Interventions

The brain is a most complex organ, and injury/ tumours can affect the overall functioning of the body. It generally requires a multidisciplinary therapeutic strategy for effective management. Although most patients have surgery, radiation, and chemotherapy at first, there is a possibility that the tumor will recur. This process generates novel challenges for patients and clinicians.

A study revealed that approximately 56.7% of patients who had another brain tumor recurrence after surgery, 27.2% had the tumor return in the same spot where it was removed, with an average recurrence of 5.6 months. 

Treatment options for recurrent brain tumors, including surgery and non-surgical methods, play a crucial role in helping patients achieve better outcomes and improved futures.

What is Brain Tumour Recurrence, Causes, and Symptoms?

The brain tumour recurrence describes a situation in which the tumour can remain or grow again despite the treatment. It may arise because of the sheer number of potential causes, some of which are

• Type of cancer: Different cancers have different probability of recurrence.
• Stage of cancer: Advanced cancer stages may have more chances of recurrence.
• Grade of the original tumour: High-grade tumours can recur more frequently.
• Previous treatment: Ineffective or incomplete treatment can result in tumour recurrence.
• Your age and health:Younger patients with overall health have better recovery rates, thus lowering a recurrence chance.
• Family history: A similarity in genetic constituent can be another factor for cancer recurrence.

Tumour recurrence is a complex clinical phenomenon and can be difficult to diagnose based on typical symptoms.

The best neurosurgeons in India identify recurrence symptoms that can be similar to the primary tumour symptoms, such as

• Headaches
• Fatigue
• Lumps and thickness that are present under the skin
• Change in skin colour—redness and darkening of the skin
• Unexpected bleeding
• Sudden weight loss or weight gain

Diagnostic procedures (including MRI and CT scan) play an important role in the detection of recurrence, and these examinations have a relevance in understanding how the tumor is moving.

• The recurrence condition frequently requires more involved treatment demands.
• Survival rates are associated with tumour type, size, and response to therapy.

Surgical Interventions for Brain Tumor Recurrence: Types, Challenges, and Management

The surgical interventions offer multiple many types of surgeries and have a ample of benefits. Some of them are discussed below

• Surgery continues to be an essential therapeutic approach in brain tumour recurrence for the demonstration of the tumours as per the access availability. 
• Brain stimulation ameliorates symptoms, enhances neurological function, and increases survival. 
• The surgical pathway depends on the size, localisation and invasion with adjacent brain tissue of the tumour.

Types of Surgical Options

• Craniotomy: The ancient procedure consists of a craniotomy of the skull to extract the tumour. The method can be used to achieve the greatest possible tumour resection whilst avoiding vascular structures in important brain regions.
• Minimally Invasive Surgery: Sophisticated methods like stereotactic surgery rely on computer-controlled instruments and miniaturised incisions for accurate placement of tumor targets with high workability.
• Endoscopic Surgery: A minimally invasive technique to access deep brain lesions through small incisions guided by an endoscope.
• Resection vs. Biopsy: Resection is the procedure where the whole tumor is being removed, and biopsy for only a tissue sample extraction purposes.

Benefits of Surgical Intervention in Tumour Recurrence

• Alleviates brain pressure, thus improving symptoms.
• Cognitive and motor functions are improved, resulting in improved quality of life.
• Allows for post-surgery treatment options.
• The chances of recurrence are low.
• Improve survival rate for certain tumour types such as low grade gliomas and meningiomas.

Challenges of Surgery

• Procedures close to the critical areas of the brain come with risks (dysarthria, muscle paralysis, neurosis). 
• Complications are infections, bleeding, oedema, and prolonged rehabilitation.

Post-Surgical Care for Tumor Management

• Post-operative management includes rehabilitation in order to regain motor, cognitive, and speech function. 
• Patients can be followed with recurrent imaging studies to detect any potential tumor regrowth or recurrence and therefore to plan prompt treatment in case of occurrence.

Non-Surgical Interventions for Brain Tumour Recurrence

The non-surgical interventions can help manage brain tumour recurrence without surgery. Some of the ways through which it can be managed. 

• Radiotherapy

Radiation therapy slows tumour progression and alleviates symptoms. Some of the advanced radiotherapy treatment options are discussed below

• External Beam Radiation: This technique is employed to deliver a given volume of radiation to a specific target tumour volume while avoiding healthy tissue.
• Stereotactic Radiosurgery (SRS): A technique that uses a very strong dose of radiation delivered in a very focal way to the tumour.
• Gamma Knife: A highly focused type of SRS, which employs gamma ray beams for the delivery of brain tumour irradiation in a single session with high accuracy.
• CyberKnife: A radiosurgery system end-to-end with high accuracy, non-invasive radiation treatment. Most importantly, it is particularly useful for treatment of sensitive or hard-to-access tumours and for the repeated treatment over several sessions, which can minimise the risk of damage to normal tissue.
• Proton Therapy: The method focuses on precise targeting, reducing the side effects on surrounding tissues.

Nevertheless, toxicity, such as fatigue, amnesia, and radiation-induced inflammation, can occur. However, with consistent monitoring, these side effects can be managed effectively.

• Targeted Therapy & Immunotherapy

This includes certain target-based drugs, personalised medicines that are tailored according to the patient’s needs, and vaccine-based therapy.

Targeted Therapy

• Bevacizumab (Avastin): Inhibits tumour blood vessel formation, slowing growth.
• Precision Medicine: Develops treatments tailored to the patient’s tumour genetics.

Immunotherapy:

• Mechanism: Improves the ability of the immune system to recognise and kill tumour cells.
• Examples: Vaccines, immune checkpoint inhibitors, and cell-based therapies offer promising experimental approaches.

What are the Chances of Brain Tumor Recurrence?

There is no certainty that the brain tumour is removed completely or not. As per Central Brain Tumor Registry of the United States Statistical Report, about 90 percent of patients with glioblastoma will experience a recurrence.

Challenges Involved in Tumor Treatment Procedures: Surgical and Non-Surgical Interventions

However, brain tumour treatment costs in India are available at affordable prices with advanced diagnostic centers.

• Accessibility Issues: Access to specialist cancer centers and new therapies is still constrained in much of the world. Global health programs are making efforts to increase access and reduce health disparities.

• Research and Development: Active research makes significant advances in life, such as drug therapies and precision oncology. Clinical trials are of pivotal importance to the development of treatment guidelines.

• Potential Risks: Emerging therapies provide hope with a brain tumor surgery success rate of approximately 70% in age 40 and younger, but also risk, including unpredictable side effects and inconsistent success rates, due to the experimental nature of certain treatments.

• Ethical Considerations: Ethical issues to address are patient consent for experimental therapies, allocation of health care resources in a fair and appropriate manner, and meeting patient expectations of treatment results.
