Ewing Sarcoma Cancer Doctor in Kolkata
Ewing sarcoma is a type of cancer that affects bones or soft tissues, primarily in children, teenagers, and young adults. It often arises during puberty, a time of rapid bone growth. Ewing sarcoma tumours commonly develop in the arms, legs, and pelvis. Symptoms can include bone pain, swelling, and fever. To get Ewing sarcoma cancer treatment in Kolkata, reach out to the cancer specialist.
Symptoms of Ewing Sarcoma
Ewing sarcoma signs and symptoms generally originate in or around a bone, most commonly affecting the legs and pelvis.
When symptoms occur in these areas, they may include:
- A lump in the arm, leg, chest, or pelvis
- Bone pain
- A fracture (break in a bone)
- Pain, swelling, or tenderness near the affected area
In some cases, Ewing sarcoma can also lead to systemic symptoms, such as:
- Fever
- Unintentional weight loss
- Fatigue
In case you experience these symptoms, consult with the ewing sarcoma oncologist in Kolkata for treatment.
Causes of Ewing Sarcoma Cancer
The exact cause of Ewing sarcoma is unknown. Experts believe it begins with a change in the DNA of certain cells, which contain instructions that guide cell behaviour. When these instructions are altered, the affected cells can start to multiply uncontrollably, harming healthy cells in the process. This leads to the formation of tumours made up of abnormal cells that may spread to other parts of the body.
These DNA changes impact the EWSR1 gene. If the doctor suspects Ewing sarcoma, your cells may be tested for alterations in this gene.
Stages of Ewing Sarcoma cancer
Ewing's sarcoma is staged using the following system:
Stage 1: Localised
The tumour is confined to the bone or soft tissue where it originated and has not spread to nearby lymph nodes or other parts of the body.
Stage 2: Localised with Regional Spread
The tumour is still localised, but it has spread to nearby lymph nodes or soft tissues.
Stage 3: Metastatic
The cancer has spread to distant parts of the body, such as the lungs or other bones. This stage indicates advanced disease.
Stage 4: Recurrent
The cancer has returned after treatment, either in the same area (local recurrence) or in a different part of the body (distant recurrence).
Diagnosis of Ewing’s Sarcoma
Doctors will conduct a physical examination. They may also perform the following tests:
Imaging Tests
Imaging tests allow providers to closely examine your child’s bones and soft tissues to check for tumours in other areas. These tests may include:
- X-rays
- Magnetic Resonance Imaging (MRI)
- Computed Tomography (CT) Scan
- Positron Emission Tomography (PET) Scan
- Bone Scan
Biopsies
Biopsies are performed to collect tissue samples for examination by medical pathologists under a microscope. The procedures may include:
Needle Biopsy
A thin hollow needle is used to extract cells, fluid, and tissue from suspicious lumps.
Bone Marrow Aspiration
This involves collecting liquid from the spongy material inside the bone marrow to look for cancerous cells.
Blood Tests
Blood tests can help determine if cancer has spread. These tests may include:
Complete Blood Count (CBC) with Differential
Low levels of blood cells and platelets may indicate cancer.
Comprehensive Metabolic Panel
This test measures the levels of enzymes and other substances in the blood.
Lactate Dehydrogenase (LDH)
Elevated LDH levels may suggest tissue damage due to cancer.
Treatments for Ewing’s Sarcoma
Treatment for Ewing's sarcoma involves a combination of therapies tailored to the individual patient based on the tumour's location, stage, and other factors. The cancer specialist considers these factors before suggesting an ewing sarcoma cancer treatment in Kolkata. Common treatment options include:
Chemotherapy
Chemotherapy uses powerful drugs to kill cancer cells or stop them from growing. It is often the first line of treatment and may be used to shrink tumours or to eliminate remaining cancer cells.
Radiation Therapy
Radiation therapy uses high-energy rays to target and kill cancer cells. It may be used to destroy cancer cells.
Targeted Therapy
Targeted therapies focus on specific molecular targets associated with cancer. For some patients, this may involve treatments that specifically target genetic changes in the tumour, like those affecting the EWSR1 gene.
Frequently Asked Questions
How does Ewing's sarcoma differ from other types of bone cancers, such as osteosarcoma?
Ewing's sarcoma primarily affects younger patients and is characterised by small round blue cells, while osteosarcoma shows a more aggressive pattern with osteoid production and affects older adolescents and young adults.
How does chemotherapy affect the overall prognosis of patients with Ewing's sarcoma?
Chemotherapy for ewing’s sarcoma significantly improves prognosis by reducing tumour size and controlling metastasis. Overall survival rates have improved with modern chemotherapy protocols.
From which type of cells does Ewing's sarcoma arise?
Ewing's sarcoma arises from primitive neuroectodermal cells (PNET) or mesenchymal stem cells, usually in the bone or soft tissues.
What are the common symptoms of Ewing's sarcoma in the bones?
Symptoms may include localised pain, swelling, tenderness, and sometimes systemic symptoms like fever and fatigue.
Can Ewing's sarcoma metastasise to the lungs, and if so, how does this affect treatment?
Yes, Ewing's sarcoma can metastasize to the lungs. Lung metastasis requires a more aggressive treatment approach, like systemic chemotherapy.
