What is Ewing's sarcoma ?
Ewing's sarcoma is also a type of bone cancer, but it develops from immature cells in the bone or surrounding soft tissue. This cancerous tumor is most common in children and adolescents, but it can also affect adults.
What are the causes ?
Ewing's sarcoma is a type of bone and soft tissue cancer that usually develops in children and adolescents. Although the exact cause of this disease is unknown, there are some assumptions about its origins.
Here are some of the theories offered to explain the potential causes of Ewing's sarcoma:
Genetics: Research has shown that certain genetic changes can increase the risk of developing Ewing's sarcoma. Gene mutations can affect the function of proteins that regulate cell growth and division, increasing the risk of tumor cells.
Environment: environmental factors such as exposure to toxic chemicals may play a role in the development of sarcoma of Ewing. However, there is no clear scientific link between the environment and the development of this disease.
Pre-existing conditions: Some studies suggest that viral infections such as Epstein-Barr virus and HIV may increase the risk of developing Ewing's sarcoma. However, research on this link is still limited.
Growth factors: A number of growth factors may play a role in the development of Ewing's sarcoma. These proteins have an important role in the regulation of cell growth and may be involved in the process of transformation of healthy cells into cancerous cells.
What are the symptoms ?
Symptoms of Ewing's sarcoma can vary depending on the size and location of the tumor. Here are some of the common symptoms associated with this disease:
Pain: Pain is often the first symptom of Ewing's sarcoma. The pain may be localized to where the tumor is, and it may be worse at night or with physical activity.
Swelling: Ewing's sarcoma tumor may cause swelling or a lump where it is . The swelling may be visible on the skin or below the surface.
Fatigue: Fatigue is another common symptom of Ewing's sarcoma. Patients may feel tired or weak, affecting their ability to perform normal daily activities.
Fever: Some patients may experience persistent fever which may be a sign of disease-related infection.
Weight loss: Patients may lose weight for no apparent reason, which may be a sign of cancer progression .
Neurological changes: Ewing's sarcoma tumors can affect the nerves and cause changes such as tingling, muscle weakness, loss of sensation or paralysis.
Bone fractures: Patients with Ewing's sarcoma may be more prone to bone fractures due to the fragility of the the bone.
How to diagnose ?
The diagnosis of Ewing's sarcoma requires a thorough analysis of symptoms, medical history, and diagnostic tests. Here are some diagnostic tools used to diagnose Ewing's sarcoma:
Medical imaging: X-rays, CT scans, MRIs and PET scans are all medical imaging tools used to detect the presence of a tumor and to determine its location and size.
Biopsy: A biopsy is a procedure in which a small sample of tissue is taken from the tumor in order to be examined in the laboratory. This confirms the diagnosis of Ewing's sarcoma.
Blood test: A blood test may be done to detect tumor markers specific to Ewing's sarcoma, although they are not always detectable.
Lung function test: If Ewing's sarcoma is located near the lungs, lung function tests can be done to determine if the tumor is affecting the patient's ability to breathe.
The accurate diagnosis of Ewing's sarcoma is crucial in determining the most appropriate treatment plan for the patient. Early detection can improve the chances of successful treatment. Treatment may include surgery, radiation therapy and chemotherapy.
What are the treatment options ?
Ewing's sarcoma is a rare form of cancer that can develop in the bones or soft tissues of the limbs, chest, pelvis or vertebrae. Treatment options depend on the size and location of the tumor, the stage of the disease, and the age and condition of the patient. Treatment options may include:
Surgery: Surgery involves removing the tumor from bone or soft tissue. Surgery is often followed by radiotherapy and/or chemotherapy to reduce the risk of recurrence.
Radiotherapy: Radiation therapy uses high-energy x-rays to kill cancer cells. It is often given after surgery to kill any remaining cancer cells and reduce the risk of recurrence.
Chemotherapy: Chemotherapy uses drugs to kill cancer cells. It is often used in combination with surgery and/or radiation therapy to effectively treat Ewing's sarcoma.
Targeted therapies: Targeted therapies are drugs that target specific proteins present on cancer cells. They can be used in combination with surgery, radiation therapy or chemotherapy to treat Ewing's sarcoma.
Gene therapy: this technique uses genetically modified viruses to deliver therapeutic genes to cancer cells, which can help stop their growth and spread.
Ewing's sarcoma is treated using a combination of these treatment methods. In general, patients with this disease undergo a combination of surgery, radiation therapy and chemotherapy to eradicate cancer cells and prevent relapses.
How is the surgery performed ?
Here's what patients can expect during surgery for Ewing's sarcoma:
Anaesthesia: Prior to surgery, patients are put under general anesthesia to keep them comfortable and to prevent them from feeling pain during the procedure.
Surgical Incision: The surgeon will make an incision in the tumor area to access the tumor and remove it. The size and location of the incision depends on the location of the tumor.
Tumor removal: The surgeon will remove the entire tumor. If the tumor is in a bone, the surgeon can replace the part of the bone that was removed with a prosthesis.
Reconstruction: After the tumor is removed, the surgeon may perform surgical reconstruction to restore the form and function of the area .
Post-operative care: After surgery, patients may experience pain. Analgesics are usually given to relieve this pain. Patients may also undergo physical therapy to improve their mobility and recovery.
What is the recovery period ?
The recovery period after surgery for Ewing's sarcoma varies depending on the patient and the extent of the procedure. Recovery can take from a few weeks to several months, depending on the severity of the disease and the postoperative care required.
Here is what patients can expect during their recovery period:
Hospitalization: After surgery, patients may be hospitalized for a few days to a few weeks, depending on the extent of the procedure and their general state of health.
Pain: Patients may experience pain and discomfort during the recovery period. Analgesics are usually prescribed to relieve pain. It is important to follow medical instructions to avoid excessive pain and promote rapid healing.
Wound Care: Patients will need to take care of their postoperative wounds to prevent infections and complications. Dressings may need to be changed regularly, and patients should watch for signs of infection, such as fever, excessive pain, and swelling.
Physiotherapy: For patients with Ewing's sarcoma located on the limbs, physiotherapy is an important part of their recovery period. Gentle movements can be encouraged to help restore muscle strength and mobility.
Medical follow-up: Patients should have regular follow-up visits with their medical team to monitor their condition and to monitor their healing progress. Patients may also be given x-rays and other tests to check if the tumor has been completely eradicated.
What are the advantages ?
Treatment for Ewing's sarcoma can be difficult and complicated, but it can provide several benefits for patients. Below are some of the most important benefits of Ewing's sarcoma treatment:
Cure: By completely removing the tumor, treatment for Ewing's sarcoma can cure the disease and allow patients to regain their health and quality of life.
Reducing the risk of recurrence: Treatment of Ewing's sarcoma can significantly reduce the risk of the tumor coming back, thanks to using a combination of surgery, radiotherapy and chemotherapy.
Improving limb mobility: By removing the tumor, surgical treatment for Ewing's sarcoma may allow patients to regain their normal mobility of the limbs, especially in the case of the tumor located on the arms or the legs.
Pain reduction: Treatment of Ewing's sarcoma can reduce the pain associated with the disease, thereby improving the patient comfort and quality of life.
Improved quality of life: With a combination of effective treatments, patients with Ewing's sarcoma can regain their quality of life and resume their professional and social activities.
What are the risks and complications ?
Although treatments for Ewing's sarcoma can be effective, there are certain risks and complications associated with these treatment options. Ewing sarcoma patients and their family members need to be aware of these risks in order to make informed decisions about their treatment and care plan. Potential risks and complications include:
Side effects of treatment: Surgery, radiation therapy and chemotherapy can cause side effects including fatigue, infections, nausea and vomiting, hair loss, loss of appetite and low blood counts. Patients should follow medical instructions strictly to avoid or reduce these side effects.
Allergic reactions and other complications: Drugs used in chemotherapy can cause severe allergic reactions, as well as other complications, such as bleeding and blood clots. Patients should inform their medical team of any signs of a serious allergic reaction.
Loss of function and range of motion: In some cases, surgery to remove the tumor may result in loss function and range of motion, especially if the tumor is located on the limbs.
Surgical Complications: Possible surgical complications include infection of the operated area, pain, and excessive bleeding. Patients should discuss these risks during their surgical consultation.
Post Traumatic Stress Disorder (PTSD): Patients with Ewing's Sarcoma can face many emotional stresses, such as anxiety, depression and PTSD. It is important that patients have access to emotional support resources during their treatment.
Tumor recurrence: Even after effective treatment, Ewing's sarcoma can recur in certain parts of the body . Patients should have regular post-operative examinations to monitor for any possible recurrence.
Ewing's sarcoma is a rare form of bone and soft tissue cancer that can affect children and young adults. Although this cancer can be difficult to treat, the combination of treatment options such as surgery, radiation therapy, and chemotherapy offers some possibility of cure and improves the quality of life for patients.
However, it is important that patients with Ewing's sarcoma also understand the risks and complications associated with these treatment options, such as side effects, allergic reactions, loss of function, surgical complications, and possible recurrence. Regular follow-up care and monitoring is therefore essential to ensure that the treatment has been effective and to prevent any recurrence.
