Ewing Sarcoma Treatment in Delhi

Ewing Sarcoma is a rare and aggressive form of cancer that primarily affects bones and soft tissues. It most commonly occurs in children, adolescents, and young adults, usually between the ages of 10 and 20. While Ewing Sarcoma is considered rare, accounting for only about 1% of all childhood cancers, it is important to understand the severity of this disease and the impact it can have on individuals and their families.

Ewing Sarcoma was first identified by James Ewing, an American pathologist, in the early 20th century. In 1921, Ewing reported on a series of cases involving tumours in bone that were previously unrecognised as a distinct type of cancer. These tumours were later named after him in recognition of his groundbreaking work. Since its discovery, research has been ongoing to better understand Ewing Sarcoma and develop effective treatment options. Today, advancements in medical technology and improved understanding of the disease have greatly enhanced our ability to diagnose and treat this condition.

Ewing Sarcoma Symptoms

Recognising the signs and symptoms of Ewing Sarcoma is crucial for early detection and successful treatment. Here are some common signs to watch out for:

• Persistent pain and swelling in the affected area
• A lump or mass that feels firm to the touch
• Easy fractures or bone breaks without significant trauma
• Fatigue and unexplained weight loss
• Fever, especially if it is accompanied by bone pain.

Ewing Sarcoma Causes

Understanding the causes of Ewing Sarcoma is crucial in developing effective prevention strategies and treatment options for those affected by this disease.

Genetic Factors

• In most cases, Ewing sarcoma is not inherited and arises from random genetic changes.
• However, a small percentage of cases are associated with specific genetic alterations, such as translocations involving the EWSR1 gene on chromosome 22.
• These genetic changes can lead to the fusion of the EWSR1 gene with other genes, resulting in the production of abnormal proteins that promote the development of cancer cells.

Environmental Factors

• Exposure to certain environmental factors has been linked to an increased risk of developing Ewing sarcoma.
• Radiation therapy for previous cancers or diagnostic procedures involving radiation may play a role in the development of Ewing sarcoma.
• Chemical exposures, such as benzene and other industrial chemicals, have also been implicated in some cases.

Types of Ewing Sarcoma

It is important to understand the different types of Ewing Sarcoma to ensure accurate diagnosis and appropriate treatment. There are three main types of Ewing Sarcoma:

Ewing's sarcoma of bone

• This is the most common type of Ewing Sarcoma, accounting for about 85% of cases.
• It typically affects the long bones, such as the arms, legs, pelvis, and ribs.
• Symptoms may include pain, swelling, and limited range of motion in the affected area.

Extraosseous Ewing tumour (EOE)

• Unlike Ewing's sarcoma of bone, EOE develops outside the bone in soft tissues or organs.
• It can occur in various locations, such as the chest wall, abdomen, head and neck, or extremities.
• Symptoms depend on the specific location and may include pain, swelling, or a mass.

Peripheral primitive neuroectodermal tumour (PNET):

• PNET is closely related to Ewing Sarcoma and shares similar genetic changes.
• It can occur in both bone and soft tissue.
• PNETs commonly develop in the chest wall, pelvis, or extremities.

Ewing Sarcoma Diagnosis

When it comes to diagnosing Ewing Sarcoma, there are several tests and procedures that doctors use to confirm the presence of the disease. These diagnostic methods play a crucial role in early detection and developing a treatment plan. Let's take a closer look at some of the key diagnostic tools used for Ewing Sarcoma.

Imaging Tests

• X-rays: This common imaging test uses low levels of radiation to create detailed images of the bones. X-rays can help identify tumours or abnormalities in the affected area.
• Magnetic resonance imaging (MRI): An MRI uses powerful magnets and radio waves to produce detailed images of the body. It can help determine the size and location of tumours, as well as if cancer has spread to nearby tissues.
• Computed tomography (CT) scan: A CT scan combines multiple X-ray images to create cross-sectional images of the body. It provides more detailed information about the size, shape, and location of tumours compared to traditional X-rays.
• Positron emission tomography (PET) scan: A PET scan involves injecting a small amount of radioactive material into the body, which is then detected by a special camera. This test helps identify areas with increased metabolic activity, indicating the presence of cancer cells.
• Bone scan: During a bone scan, a small amount of radioactive material is injected into a vein. The material travels through the bloodstream and accumulates in areas where there may be abnormal bone growth or cancer spread.

Biopsy Procedures

• Needle biopsy: In this procedure, a small needle is used to extract a sample from the suspected tumour site. The sample is then examined under a microscope to determine if it contains cancer cells.
• Bone marrow aspiration: This procedure involves using a long needle to extract a sample of bone marrow from within certain bones. The sample is examined under a microscope to check for the presence of cancer cells.

Blood tests

• Complete blood count (CBC): A CBC measures the number of different types of blood cells present in a sample. Abnormalities in the blood cell counts can indicate the presence of Ewing Sarcoma.
• Comprehensive metabolic panel: This blood test provides information about kidney and liver function, as well as electrolyte levels. It helps assess overall health and detect any abnormalities that may be associated with Ewing Sarcoma.
• Lactate dehydrogenase (LDH): Elevated levels of LDH in the blood can suggest the presence of cancer cells, including Ewing Sarcoma.

Stages of Ewing Sarcoma

Understanding the stages of Ewing Sarcoma is crucial for effective treatment and management. The stages of Ewing Sarcoma are classified based on the extent of the tumour's spread. Let's take a closer look at each stage:

Stage I - Early Stage

• At this stage, the tumour is confined to the bone where it originated.
• It has not spread to nearby tissues or organs.
• The cancer is localised, making it more manageable and increasing the chances of successful treatment.

Stage II - Localised

• In stage II, the tumour may have grown larger but is still confined to the original site.
• It may involve nearby tissues or structures such as muscles or blood vessels.
• However, it has not spread to distant areas of the body.
• Cancer treatment options at this stage often involve a combination of surgery, radiation therapy, and chemotherapy.

Stage III - Regional Spread

• At stage III, the tumour has extended beyond its original location and may have reached nearby lymph nodes.
• Despite regional spread, it has not yet metastasised to distant sites.
• Treatment for stage III Ewing Sarcoma typically involves a combination of chemotherapy, radiation therapy, and surgery.

Stage IV - Distant Spread

• Stage IV Ewing Sarcoma indicates that the cancer has metastasised or spread to distant sites in the body.
• It may involve multiple bones, organs, or even lungs.
• Despite its advanced stage, treatment options are available to help manage the disease and improve survival rates.
• Treatment for stage IV Ewing Sarcoma usually includes chemotherapy, radiation therapy, targeted therapies, and sometimes surgery.

Ewing Sarcoma Treatment

When it comes to treating Ewing sarcoma, there are several approaches that medical professionals may take. These treatments can include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy. Each method plays a vital role in fighting this aggressive disease and improving the chances of recovery and survival. Let's take a closer look at each treatment option and its significance in combating Ewing sarcoma.

Surgery

• Surgery is often the primary treatment for Ewing sarcoma.
• The goal of surgery is to remove the tumour and any surrounding affected tissue.
• In some cases, limb-sparing surgery may be performed, which involves removing the tumour while preserving as much function and appearance as possible.
• In more advanced cases or when the tumour cannot be completely removed, amputation may be necessary.
• Following surgery, patients may require additional treatments such as chemotherapy or radiation therapy to target any remaining cancer cells.

Chemotherapy

• Chemotherapy is commonly used in conjunction with other treatments for Ewing sarcoma.
• It involves the use of powerful drugs to kill cancer cells throughout the body.
• Chemotherapy is typically administered in cycles, allowing time for the body to recover between treatments.
• This approach helps to eliminate any cancer cells that may have spread beyond the primary tumour site.
• The specific chemotherapy drugs used may vary based on individual cases and treatment plans.

Radiation therapy

• Radiation therapy utilises high-energy X-rays or other forms of radiation to destroy cancer cells.
• It is often utilised after surgery or in combination with chemotherapy to target remaining cancer cells.
• Radiation therapy can be delivered externally (external beam radiation) or internally (brachytherapy).
• The precise dosage and duration of radiation treatment will be determined by the medical team based on various factors.

Immunotherapy

• Immunotherapy is a groundbreaking treatment option that stimulates the body's immune system to fight cancer.
• It works by boosting the immune response or by using antibodies to target specific cancer cells.
• While still being researched and developed for Ewing sarcoma, immunotherapy shows promising potential as a complementary treatment.

Targeted Therapy

• Targeted therapy is a form of treatment that focuses on specific genetic alterations within cancer cells.
• By identifying these alterations, targeted therapy can block the growth and spread of cancer cells.
• While not yet extensively used for Ewing sarcoma, ongoing research is exploring the potential benefits of targeted therapy.

Risks Associated with Ewing Sarcoma

While the exact cause of Ewing Sarcoma is still unknown, several risk factors have been identified. Understanding these risk factors can help individuals and healthcare professionals identify those who may be at a higher risk of developing Ewing Sarcoma.

Age

• Ewing Sarcoma primarily affects children and young adults between the ages of 10 and 20.
• The risk of developing Ewing Sarcoma decreases significantly after the age of 30.
• The highest incidence rates are observed in individuals between the ages of 15 and 19.

Genetics

• Certain genetic mutations or chromosomal rearrangements have been linked to an increased risk of developing Ewing Sarcoma.
• The most common genetic abnormality associated with this cancer is the translocation between chromosomes 11 and 22, resulting in the formation of a fusion gene known as EWSR1-FLI1.
• Individuals with a family history of Ewing Sarcoma or other genetic syndromes, such as Li-Fraumeni syndrome or neurofibromatosis type 1, may have a higher risk of developing the disease.

Other Health Conditions

• There is some evidence to suggest that individuals with certain pre-existing health conditions may have an increased risk of developing Ewing Sarcoma.
• For example, individuals with retinoblastoma (a form of eye cancer) or Paget's disease (a bone disorder) may have a higher likelihood of developing Ewing Sarcoma.
• However, it is important to note that these conditions are rare, and having them does not necessarily mean that an individual will develop Ewing Sarcoma.

Complications of Ewing Sarcoma

While the main focus in treating Ewing Sarcoma is to eradicate the cancerous cells, it's important to be aware of the potential complications that may arise during and after treatment.

Cancer that spreads

• In some cases, Ewing Sarcoma may spread to other parts of the body, such as the lungs, bones, or bone marrow.
• This is known as metastatic cancer and can make treatment more challenging.

Metastatic cancer

• When Ewing Sarcoma spreads, it can cause tumours to form in different organs or bones.
• The spread of cancer cells can interfere with their normal function, leading to further health complications.

Recurrent cancer

• Even after successful treatment, there is a risk of Ewing Sarcoma returning.
• This is known as recurrent cancer and may require additional therapy or treatment options.

Long-term Effects

• Survivors of Ewing Sarcoma may experience long-term effects from the disease and its treatments.
• These effects can include physical disabilities, such as limb deformities or difficulty with mobility, as well as emotional and psychological challenges.
