Chordoma

Chordoma is a rare bone cancer found in the spine or skull base. It comes from leftover cells from early fetal development. This cancer is rare but can greatly affect those who have it.

Chordomas make up less than 1% of bone cancers. They can appear anywhere along the spine, from the skull to the tailbone. These tumors grow slowly and can cause pain and other issues. Knowing about this cancer helps doctors find it early and treat it better.

What is Chordoma?

Chordoma is a rare, slow-growing tumor that comes from notochordal remnants. These are parts left over from the notochord, an early structure in our development. Tumors can grow anywhere from the skull base to the tailbone, most often in the clival, sacral, and spinal areas.

Chordomas are a type of sarcoma, growing from connective tissue. They look unique under a microscope, with cells that have vacuoles and a mucus-like substance. Even though they grow slowly, they can be aggressive and spread to other parts of the body.

Definition and Origin

Chordomas start as tumors in the bones from notochordal remnants. The notochord is a structure that helps form the spine during fetal development. Usually, it disappears after birth, but sometimes, parts stay and can cause chordomas later in life.

Prevalence and Risk Factors

Chordoma is a rare cancer, affecting about 1 in a million people each year. It often shows up in adults between 50 and 70 years old. Men are slightly more likely to get it than women.

What causes chordoma isn’t fully known, but some risk factors have been found. These include:

• Genetic predisposition, like mutations in the T (brachyury) gene
• Prior radiation to the affected area
• Possible link to certain genetic disorders, like tuberous sclerosis complex

Knowing about chordoma’s definition, origin, how common it is, and its risk factors is key. It helps in early detection, accurate diagnosis, and planning the right treatment for those with this rare tumor.

Types of Chordoma

Chordomas are classified by where they occur in the body. The main types are clival chordoma, sacral chordoma, and spinal chordoma. Each type has its own challenges because of its location and treatment complexity.

Clival Chordoma

Clival chordomas happen at the skull’s base, in the clivus bone. They can press on or invade nearby nerves and blood vessels. Symptoms include headaches, vision issues, and trouble speaking or swallowing. About 25-35% of chordomas are clival.

Sacral Chordoma

Sacral chordomas are found in the sacrum, at the spine’s base. They are the most common, making up 50-60% of cases. Symptoms include lower back pain, numbness, and leg weakness. They can also affect bowel or bladder function if they press on nerves.

Spinal Chordoma

Spinal chordomas occur in the spine’s bones (vertebrae). They are the least common, making up 10-15% of cases. They can happen anywhere in the spine, from the neck to the lower back. Symptoms vary by location but often include pain, weakness, or numbness.

The table below summarizes the key characteristics of each chordoma type:

Knowing the differences between clival, sacral, and spinal chordomas is key for accurate diagnosis and treatment. Specialists like neurosurgeons and orthopedic oncologists work together. They create personalized treatment plans based on the tumor’s location and how far it has spread.

Symptoms and Diagnosis

Chordoma symptoms can vary based on the tumor’s location and size. Early signs are often subtle and easy to miss. This makes it hard to diagnose chordoma early.

Common symptoms include pain, numbness, weakness, and changes in bowel or bladder function. As the tumor grows, it can press on nerves and structures. This leads to more noticeable symptoms.

If chordoma is suspected, several tests may be done. Imaging tests are key in diagnosing chordoma. They show the tumor and the tissues around it. The most common tests are:

While imaging tests are helpful, a biopsy is usually needed to confirm chordoma. A biopsy takes a small sample of the tumor. A pathologist then examines it under a microscope.

This analysis helps figure out the type of chordoma and how aggressive it is. It guides treatment choices.

Early detection and accurate diagnosis are key to better outcomes for chordoma patients. If you have persistent symptoms or health concerns, see a doctor. They can check your case and suggest the right tests to find out if you have chordoma or something else.

Staging and Grading of Chordoma

Doctors use staging and grading to classify chordoma tumors. They look at the tumor’s size, how far it has spread, and how different its cells are. This helps decide the best treatment and what the patient’s future might look like.

Staging Systems

The TNM (Tumor, Node, Metastasis) system is often used for chordoma. It checks the tumor’s size, if it’s in nearby lymph nodes, and if it’s spread to other parts of the body. Here are the TNM stages for chordoma:

Grading Classifications

Chordoma grading looks at how the tumor cells look under a microscope. Tumors are graded as low-grade (well-differentiated) or high-grade (poorly differentiated). Well-differentiated chordomas look more like normal tissue and grow slowly. Poorly differentiated chordomas have abnormal cells and grow faster.

Knowing the stage and grade of a chordoma helps doctors plan the best treatment. It also helps predict how the patient will do. Accurate staging and grading are key to managing chordoma and improving patient care.

Treatment Options for Chordoma

Treating chordoma requires a team effort. Doctors use different treatments to get the best results. The treatment plan depends on the tumor’s location, size, and stage. It also considers the patient’s health and what they prefer.

Surgery

Surgery is often the first step in treating chordoma. The goal is to remove as much of the tumor as possible. This is done while keeping healthy tissue and important structures safe.

En bloc resection is the preferred method. It means removing the tumor in one piece to lower the chance of it coming back. But, it’s not always possible because of where the tumor is.

Radiation Therapy

Radiation therapy is used with surgery to kill any cancer cells left behind. It helps prevent the tumor from coming back. Proton beam therapy is very effective for chordoma because it targets the tumor without harming nearby healthy tissue.

Other types of radiation therapy, like intensity-modulated radiation therapy (IMRT), might also be used.

Targeted Therapy and Immunotherapy

Targeted therapy and immunotherapy are new ways to treat chordoma. Targeted therapies, like imatinib and erlotinib, work on specific molecules that help tumors grow. They can slow or stop the tumor by blocking these molecules.

Immunotherapy uses the body’s immune system to fight cancer. Immune checkpoint inhibitors, such as nivolumab and pembrolizumab, are showing promise in treating chordoma that has spread or come back.

Prognosis and Survival Rates

The chordoma prognosis and long-term outcomes depend on several factors. These include the tumor’s location, stage, and grade at diagnosis. Early detection and treatment lead to better survival rates. But, chordomas grow slowly, making recurrence a common issue even after treatment.

Recent studies show that chordoma patients have a 70% 5-year survival rate. The 10-year survival rate is about 40%. Survival rates differ based on the chordoma type:

These are average survival rates. Individual outcomes can vary. The extent of surgery, radiation, and the patient’s health all play a role in long-term success.

Chordoma’s high recurrence rate is a major challenge. Studies indicate a 40-50% recurrence rate within 5 years. Regular follow-ups are key to catching and treating recurrences early, improving survival chances.

Research is ongoing to better understand chordoma and find new treatments. Clinical trials are exploring targeted and immunotherapies. These may lead to better outcomes for patients with this rare cancer.
