What is Osteosarcoma?

 Osteosarcoma also called osteosarcoma, is a type of osteosarcoma. This happens when the cells that make up new bone form a cancerous tumor. Treatment (chemotherapy and surgery to remove cancer) is usually successful if diagnosed early before the disease spreads. 

 Anyone can develop osteosarcoma, the most common type of osteosarcoma in children and adolescents. Teenage boys are most likely to get it. 

 In children and adolescents, osteosarcoma often occurs at the ends of long bones, where the bone grows fastest. 

Osteosarcoma 

 Most tumors begin around the knee, either in the lower part of the femur or in the upper part of the tibia. It may also grow on the humerus near the shoulders. However, osteosarcoma can occur in any bone, especially in the elderly, including: 

•  pelvis: 
•  shoulder 
•  skull

Symptoms of Osteosarcoma:

The warning signs are: 

• Swelling or lumps around the bone or the edges of the bone 
•  Bone or joint pain or pain. This pain can come and go for months. 
•  Fracture for no apparent reason 
•  Night pain 
•  Post-exercise  pain 
•  Loose 

 Somebody pain and swelling are common in active and growing children. If these signs do not go away or worsen after a few weeks, talk to your doctor.

Types of Osteosarcoma:

Depending on how the cells look under the microscope, doctors classify osteosarcoma into three subtypes. 

 High-grade osteosarcoma:

 This is the fastest growing type with cells of abnormal appearance. Most osteosarcomas in children and adolescents are of high grade. The most common types are: 

•  Osteoblasts 

Osteoblasts

•  Chondroblasts

Chondroblasts

•  Fibroblast 

Fibroblasts

 Low-grade osteosarcoma: 

This subtype grows slowly. The cells look like normal bone. Parabone (paracortex) 

 Well-differentiated intramedullary or intraosseous.

 Moderate osteosarcoma:

 It lies between high-grade and low-grade tumors. It's rare. The main type is called the periosteum or paracortex. 

 Risk factors of Osteosarcoma:

 DNA or genetic code errors cause osteosarcoma. Bone growth cells inadvertently form tumors. 

 Some things, such as the following, can increase your chances of developing osteosarcoma: 

 Age:

Teens with a surge in growth are most likely to get it, especially if they are growing fast.

 sex:

 Osteosarcoma is common in men. height. Older children are at higher risk.  Treatments such as radiation therapy for other types of cancer and cancer treatments called alkylating agents 

 Your genes, such as Paget's bone disease, Li-Fraumeni syndrome, Rothmund-Thomson syndrome, Bloom syndrome, Werner syndrome, Diamond-Blackfan anemia, or certain eye cancers known as hereditary retinoblastoma. 

 Diagnosis of osteosarcoma :

 Your appointment includes: 

 History and physical examination. Your doctor will ask you about your personal and family medical history. Look for any abnormal lumps around the bone. Image inspection. X-rays, CT scans, MRIs, bone scans, and PET scans can show abnormal bone changes that may be a sign of osteosarcoma.

Pet Scans

It can also indicate areas where the tumor may have spread. biopsy. The doctor will take a small sample of bone or tissue from the painful or swollen area. You can use a needle or make a skin incision called a surgical biopsy or a laparotomy biopsy. An expert observes the sample under a microscope.

 This test can see cancer cells in the bone and cancer cells that have spread to muscles and other areas. 

  Treatment of osteosarcoma:

 Treatment depends on several factors, such as where the tumor is, how fast the tumor is growing, and whether the tumor is spreading. Your age and general health are also taken into account. Treatment  

 is most effective when cancer has started before it has spread beyond the bone to other tissues and organs. Most people detect tumors early because they can cause pain, swelling, or dragging. Tell your doctor about these warning signs so that you can start treatment as soon as possible.  Most people with 

 osteosarcoma require surgery and chemotherapy. Some people receive radiation therapy.

Surgery:

 The purpose of surgery is to get rid of all cancer. Even the few cells left can grow into new tumors. Depending on your case, your doctor may perform one of these steps: 

 limb-sparing surgery:

 Your doctor will remove the tumor in your arms and legs and some of the surrounding tissue. The medical device or prosthesis fills some or all of the remaining gaps in the bone. There may also be bone grafts that use bone fragments from another part of the body or a donor.

 Disconnect If the tumor is large and invades nerves or blood vessels, your doctor may need to amputate or remove all or part of your legs or arms. You can choose a prosthesis or a prosthesis.

 Rotating plastic:

 If the doctor needs to remove the leg above the knee, the lower leg and part of the foot can be reattached to the femur. With the help of a prosthesis, your ankle acts as a new knee joint. Osteosarcomas of the pelvis, jawbone, spine, or skull can be more difficult to remove completely by surgery.

 Radiation therapy may also be needed. If cancer has spread to the lungs or other parts of the body, a doctor may need to remove these tumors. 

 Chemotherapy: 

 "Chemotherapy" uses powerful medicines to kill or stop the growth of cancer cells. You usually get them through the IV of your veins. 

 Doctors treat most osteosarcomas with chemotherapy. The drug can shrink the tumor and facilitate surgery. They also eliminate small clusters of cancer cells that doctors may not be able to see on medical scans. 

Chemotherapy

 Side effects include nausea and vomiting, diarrhea, and loss of appetite. Children usually take higher doses of medication because they have fewer serious side effects from chemotherapy than adults. 

 Radiation therapy:

Radiation Therapy

 High-energy x-rays can kill cancer cells. 

 Radiation does not work well with osteosarcoma cells like other types of cancer. However, if surgery cannot remove all cancer, doctors may use a procedure called external beam radiation therapy. This often happens when there is a tumor in the hip or jawbone. 

Jaw Bone

 In this form of treatment, the machine concentrates a  high-energy beam on the tumor, killing the remaining cancer cells. 

 New Therapies:

 Scientists are studying the best combinations of chemotherapeutic drugs to treat osteosarcoma and testing new types of drugs. They are also working on more intense and more targeted radiation therapy. 

New Therapies

 We recommend that you consult your doctor about clinical trials. This is a way for professionals to test new treatments before they become widely available. Your doctor can help you find the right one for you and help you understand what is at stake.

Complications of Osteosarcoma:

Osteosarcoma and its treatment can cause complications, including: 

  fractures 

•  Wound infection and slow healing 
•  Donor bone graft or prosthesis problems 

 prosthesis problems 

•  Side effects of chemotherapy such as anemia
•  Bleeding
•  kidney or liver damage
•  Hearing loss
•  Another high risk of cancer
