Treatment for advanced and metastatic disease

Chordomas are considered advanced when an isolated recurrence cannot be treated with high-dose radiation or when the recurrence is multifocal. Multifocal recurrences involve multiple tumors in the area of the original tumor location. Metastatic chordoma is one or more tumors that have spread to other parts of the body.

Advanced disease is very unlikely to be cured and currently there is no known cure for metastatic disease. However, multiple treatment options are available to control or temporarily stop tumor growth, as well as to alleviate symptoms. These include debulking surgery, low-dose radiation, ablative therapies, and systemic therapies. With the right care, your tumor may be controlled for many years while also maintaining a good quality of life.

This flowchart illustrates the possible treatment options for advanced and metastatic disease as discussed in the sections below.

Debulking surgery

In a debulking surgery, some of the tumor is removed in order to help relieve or avoid symptoms caused by compression of important structures such as nerves, spinal cord, or the brainstem. It can also be used to separate healthy tissues from your tumor so that you can more safely undergo radiation if necessary. Debulking surgery is recommended only in certain cases because it is not curative and the chance of serious side effects increases with each surgery.

How do I decide?

Every patient’s situation is unique. If you have advanced or metastatic disease, it is important to discuss all of these options in detail with your medical team and your family, weighing the risks and benefits of each option for your situation. The treatment options listed here involve various types of doctors, so it is important to consult with doctors who specialize in these treatments and have experience treating chordoma patients. For some patients, just one type of treatment might be the best decision, while for others a combination of treatments might provide the best option.

Low-dose radiation

Low-dose radiation may be given alone or following a debulking surgery. It is used to slow tumor progression or relieve symptoms. Your doctor should consider all previous radiation treatments and the location of the recurrent tumor to determine whether radiation is safe for you.

It may also be possible for you to have stereotactic radiosurgery (SRS) or stereotactic body radiation therapy (SBRT), which are both types of hypofractionated radiation. When hypofractionation is used, the total amount of radiation given is less but the effect is the same as standard fractionation.

Ablative therapy

There is some evidence to suggest that ablative therapies like cryoablation, radiofrequency ablation (RFA), or high-intensity focused ultrasound (HIFU) can be used to help manage symptoms caused by recurrent tumors. Cryoablation destroys cancer cells with extreme cold, while RFA uses heat. Both are delivered through small probes inserted directly into the tumor. HIFU destroys cancer cells with high-frequency sound waves delivered from outside of the body. More research is needed to determine how effective these procedures are for treating chordoma, but they are options you can discuss further with your doctors.

Systemic therapy

There are no drugs currently approved by any government regulatory agencies for the treatment of chordoma. However, evidence has shown that certain types of systemic therapies such as targeted therapy and immunotherapy that are commonly used to treat other cancers may also help patients with recurrent chordoma.

Conventional chemotherapy is typically not effective in treating chordoma. However, some patients with poorly differentiated or dedifferentiated chordoma have benefitted from sarcoma chemotherapy regimens.

Chordoma Foundation Medical Advisory Board recommendations

Although each patient’s situation is unique, in general, our Medical Advisory Board (MAB) recommends that patients considering systemic therapy treatment options do so in the following order of priority, in consultation with a chordoma-experienced medical oncologist:

1. Chordoma-specific clinical trials
Start by considering trials designed specifically for chordoma patients. These trials are likely to have strong scientific justification and be conducted by teams with significant experience caring for chordoma patients.

2. Other relevant clinical trials recommended by an experienced physician
If you are not eligible for any chordoma-specific trials, ask your oncologist about other clinical trials that may be open to you.

3. Off-label therapy with evidence of clinical benefit for chordoma patients
While there are currently no drugs approved for the treatment of chordoma, some drugs that are approved for the treatment of other cancers have shown modest activity in chordoma patients. In some countries, doctors can choose to prescribe these drugs to chordoma patients if they believe they will benefit the patient. This is called off-label use. If you are not eligible for any clinical trials, consult with your oncologist about off-label use of approved drugs that have been used to treat chordoma patients.

Consider palliative care

Palliative care, also called supportive care, can improve the quality of life and well-being of patients dealing with a serious illness by preventing and treating symptoms of the disease or the side effects of its treatment. Palliative care is often confused with hospice care or end of life care, but they are not the same. Hospice care is intended for the end of life period, generally for patients expected to live for less than six months, while palliative care is recommended for patients at any stage of a life-threatening or chronic illness.

Chordoma experts recommend that palliative care be included in all chordoma patients’ care plans from the time of diagnosis, through all stages of treatment, as well as after treatment ends. No matter what treatment you have for your recurrence, palliative care can help address pain, mobility and functional issues, mental and emotional health, nutrition, and many other concerns to help you live well while managing your chordoma.
