Neuro-Oncology is the field dedicated to the evaluation and treatment of tumors affecting the brain, spinal cord, spine, the membranes surrounding the nervous system and the skull base.
These conditions form a diverse group of diseases. Some lesions grow slowly and may be monitored through regular appointments and imaging studies. Others require more extensive investigation and treatment planning within a shorter period of time.
Each case is evaluated according to the type of tumor, its location, size and behavior, the symptoms presented and its relationship with important neurological structures.
The care strategy may involve monitoring, surgery, radiation therapy, oncological treatment or a combination of different approaches, depending on the diagnosis and the individual needs of each patient.
Neuro-Oncology includes the investigation and treatment of different conditions, such as:
• Brain tumors
• Central nervous system tumors
• Spinal cord and spinal tumors
• Skull base tumors
• Complex skull base lesions
• Metastases to the brain, spinal cord or spine
• Lesions identified on imaging studies
• Cases requiring a specialized second opinion
Each diagnosis has its own characteristics. Therefore, treatment decisions are based not only on the name of the condition, but on the complete set of clinical, neurological and radiological information for each patient.
Brain tumors may originate within the brain itself or result from the spread of a disease that began in another part of the body.
These lesions may have different growth patterns and behaviors. Some are benign, while others have malignant characteristics and require coordinated care with other medical specialties.
Symptoms vary depending on the region of the brain affected. They may include persistent headaches, seizures, muscle weakness, speech difficulties, vision loss, balance problems, cognitive changes or behavioral changes.
These symptoms may also be associated with other neurological conditions. A specialized evaluation is necessary to determine their cause and define the next steps.
Tumors may affect the spinal cord, the membranes surrounding it, the nerves or the bony structures of the spine.
Symptoms may include persistent pain, worsening pain at night, tingling, loss of sensation, reduced strength in the arms or legs and difficulty walking.
The location and extent of the lesion, as well as the presence of compression of neurological structures, are important factors in treatment planning.
Changes in bladder or bowel control, especially when accompanied by loss of strength or sensation, require immediate medical evaluation.
The skull base is a complex anatomical region located near nerves, blood vessels and structures essential to several neurological functions.
Tumors in this area may cause visual changes, hearing loss, dizziness, facial pain, difficulty swallowing, voice changes or impairment of the cranial nerves.
Treatment planning requires a detailed study of the anatomy and the relationship between the lesion and nearby structures. Each treatment option must be evaluated carefully, considering the goals of treatment and the preservation of neurological function.
In addition to tumors, other lesions may affect the skull base and require specialized evaluation.
Their location and proximity to delicate structures make individualized planning essential. Treatment decisions consider the nature of the lesion, the symptoms presented, changes observed on imaging studies and the potential risks and benefits of each approach.
Metastases are lesions that originate in another part of the body and spread to the brain, spinal cord or spine.
The evaluation considers the type of primary tumor, the number and location of the lesions, the symptoms, previous treatments and the patient’s clinical condition.
Care may involve surgery, radiation therapy, systemic treatments or a combination of modalities, in coordination with the oncology team responsible for the case.
The evaluation begins with an assessment of the patient’s symptoms, medical history and previous examinations.
Magnetic resonance imaging, computed tomography and other tests may help assess the location, extent and characteristics of the lesion.
In certain situations, a definitive diagnosis may depend on the analysis of tissue obtained through a biopsy or surgery.
The evaluation also considers the lesion’s proximity to areas responsible for movement, speech, vision, memory, balance and other neurological functions.
A Neuro-Oncology evaluation brings together clinical, neurological and radiological information to provide a comprehensive understanding of the diagnosis.
In addition to the characteristics of the lesion, the patient’s general health, the severity of symptoms, changes observed on imaging studies and the potential impact of the available treatment options are also considered.
This analysis guides the development of a care plan tailored to the specific characteristics of each case.
When surgery is indicated, planning considers the approach to the lesion, its relationship with neurological structures and the objectives of the procedure.
In some cases, it may be possible to remove the entire lesion. In others, the strategy may involve partial removal, a biopsy or reducing pressure on neurological structures.
The decision must take into account the potential benefits, limitations and risks involved. The objectives of the procedure should be explained clearly to the patient and their family.
Not every lesion identified on an imaging study requires immediate intervention.
Depending on its type, size, location, behavior and the absence of symptoms, monitoring through regular appointments and imaging studies may be recommended.
Observation is an active medical approach. It requires planning, a defined schedule for follow-up examinations and continuous reassessment of the lesion’s progression.
Neuro-Oncology care may require the involvement of different specialties, including Medical Oncology, Radiation Oncology, Neurology, Pathology, Radiology and Rehabilitation.
This coordinated approach makes it possible to evaluate the diagnosis comprehensively and organize the different stages of treatment according to the patient’s needs.
An evaluation may be recommended after a lesion is identified on an imaging study, in the presence of persistent neurological symptoms or when there is a need to better understand a diagnosis and the available treatment options.
A second opinion may also help clarify questions regarding surgery, monitoring, radiation therapy and coordination with other oncological treatments.
New-onset seizures, sudden muscle weakness, changes in consciousness or rapid neurological deterioration require immediate medical attention.
Receiving a diagnosis or suspected diagnosis of a nervous system tumor often raises questions and uncertainty.
A careful evaluation helps clarify the characteristics of the lesion, organize the next steps and discuss the available options with clarity, responsibility and attention to the needs of the patient and their family.
