Overview

Chordoma is a rare and slow-growing type of cancer that originates from remnants of the notochord, a structure that develops during foetal development. It typically occurs in the spine or skull base, causing tumours that can compress nearby structures and tissues, leading to various symptoms and complications.

An uncommon tumour, chordoma primarily occurs in the skull base, spine, and sacrum bones. Firstly, its slow-growing nature often leads to delayed diagnosis, allowing the tumour to attain a substantial size and infiltrate critical anatomical structures. This can result in debilitating symptoms such as chronic pain, neurological deficits, and impaired mobility, severely diminishing the patient's quality of life. Additionally, the rarity of chordoma can pose challenges in accessing specialised care and expertise, potentially leading to suboptimal treatment outcomes. Let's unfold more information about chordoma.

Causes of Chordoma

Mainly, the cause of chordoma is not clear, but several factors may contribute to its development:

- Genetic Mutations. Inherited genetic mutations increase the risk of developing the condition.
- Notch Signalling Pathway Aberrations. Aberrations in the notch signalling pathway have been implicated in the development of chordomas.
- Physical Trauma. There is a chance of chordoma developing in individuals who have experienced significant physical trauma or prolonged radiation exposure.
- Chordoma Risk Genes. Research has identified specific genetic mutations, such as in the T gene (T-brachyury), associated with chordoma development.
- Notochord Remnants. Chordomas are thought to arise from remnants of the notochord, a structure that plays a role in foetal development. These remnants may undergo malignant transformation over time.

Overall, genetic and environmental factors are responsible for the development of this uncommon malignancy.

Symptoms of Chordoma

The symptoms of chordoma can vary depending on the location and size of the tumour. Common symptoms may include:

- A persistent, localised pain in the affected area.
- Some individuals may experience neurological symptoms, such as numbness, weakness, or changes in sensation.
- Difficulty swallowing or breathing
- Changes in sensory functions.
- Bowel or bladder dysfunction
- Difficulty in Balance

In some cases, a visible lump or swelling may be noticeable at the site of the tumour.

Diagnosis of Chordoma

Diagnosing chordoma involves a combination of medical history review, physical examination, and imaging tests. These may include

- MRI (Magnetic Resonance Imaging): It provides detailed images of soft tissues, which is crucial for evaluating the extent and location of the tumour.
- CT (Computed Tomography) Scan: This can help in providing a more detailed view of the bones and surrounding structures.
- Biopsy: A sample of the tumour tissue is obtained for laboratory analysis to confirm the diagnosis.
- Cerebrospinal Fluid (CSF) Analysis: In cases where the tumour is in proximity to the brain or spinal cord, a lumbar puncture (spinal tap) may be conducted to analyse cerebrospinal fluid for the presence of cancer cells or tumour markers.

Treatment Options For Chordoma

Treatment options for chordoma may involve a combination of surgery, radiation therapy, and sometimes targeted therapies. The specific approach depends on factors such as the tumour's location, size, and whether it has spread to other body parts.

Surgery

Surgery is often the primary treatment for chordoma, aiming to remove as much of the tumour as possible. However, complete removal can be challenging due to the intricate location of many chordomas. Sometimes, a multidisciplinary team of surgeons, including neurosurgeons and orthopaedic surgeons, may work together to achieve the best outcome.

Radiation Therapy

Radiation therapy is commonly used in conjunction with surgery to treat chordoma. It may be administered before or after surgery to target any remaining cancer cells and reduce the risk of recurrence.

Targeted therapies and immunotherapy

Research into targeted therapies and immunotherapies for chordoma is ongoing. These treatments aim to specifically target the cancer cells, potentially providing more effective and less invasive options for patients.

Palliative Care

In cases where complete removal of the tumour is not possible or if the cancer has spread to other parts of the body, palliative care focuses on relieving symptoms, improving quality of life, and providing emotional support.

When to Consult a Doctor

You can also get in touch with the expert Oncology doctors at Narayana Healthcare based in your city to get immediate attention and medical support during injuries, health disorders or any other health concern.

Conclusion

Chordoma is a rare and complex type of cancer that requires a multidisciplinary approach to treatment. Early diagnosis and intervention can significantly improve outcomes for individuals affected by this condition. If you suspect you or someone you know may have chordoma, it is crucial to consult a healthcare professional for proper evaluation and treatment.

FAQs About Chordoma

Q. What causes chordoma? A. The leading cause of chordoma is not well understood. It is believed to be related to remnants of the notochord, a structure present during early embryonic development. Genetic mutations may also play a role in some cases.

Q. What are the common symptoms of chordoma? A. The symptoms of chordoma depend on its location. In the skull base, symptoms may include headaches, double vision, difficulty swallowing, or changes in facial sensation. In the spine or sacrum, symptoms may include back pain, weakness, or changes in bowel or bladder function.

Q. Is chordoma Curable or not? A. Chordoma is challenging to fully cure due to its aggressive nature and tendency to recur. However, with early detection and appropriate treatment, long-term survival and a good quality of life can be achieved for many patients.

Q. Who is at risk for chordoma? A. Individuals at risk for chordoma typically include those with a genetic factor, such as those with a family history of the disease. Additionally, it can occur sporadically without a clear familial link, but it is considered rare overall.

Q. What are the treatment options for Chordoma? A. Treatment for chordoma often involves a combination of surgery, radiation therapy, and sometimes targeted therapy or chemotherapy. The specific treatment plan depends on the tumour's location, size, and whether it has spread.
