Osteosarcoma bone cancer

An instance of bone cancer that starts in the cells that create bones is osteosarcoma. Although it can begin in any bone, osteosarcoma is more frequently detected in the long bones, more often the legs but occasionally the arms. In extremely rare circumstances, it can happen in soft tissue away from the bone.

Although it can affect younger children and older adults, osteosarcoma often affects teenagers and young adults.

Chemotherapy, surgery, and occasionally radiation therapy are used as treatments in most cases. Based on the osteosarcoma’s origin, size, kind, and grade, as well as if it has spread outside of the bone, doctors choose a course of treatment.

Over time, advancements in osteosarcoma treatment have significantly improved the outlook (prognosis) for this malignancy. It is advised that patients be monitored for the rest of their lives to look out for any potential long-term repercussions of their aggressive therapies.

The most typical cancer that begins in the bones is osteosarcoma, also known as osteogenic sarcoma. The cancer cells in these tumors resemble the earliest stages of the bone cells that ordinarily aid in the formation of new bone tissue, but osteosarcomas have weaker bone tissue than healthy bones do.

The majority of osteosarcomas affect children, adolescents, and young adults. Although teens are the age group most frequently afflicted, osteosarcoma can occur at any age.

Types of osteosarcoma

Osteosarcomas are categorized as high, middle, or low grade based on how the cancer cells appear under a microscope. The tumor’s grade informs medical professionals of the likelihood that the cancer may advance swiftly and spread to further organ systems.

High-grade osteosarcoma

These osteosarcoma subtypes have the quickest rate of growth. They do not resemble normal bone when viewed under a microscope, and many of the cancer cells are engaged in cell division. Most childhood and adolescent osteosarcomas are high grade. High-grade osteosarcomas come in a wide variety of varieties.

• Osteoblastic
• Chondroblastic
• Fibroblastic
• Small cell
• Telangiectatic
• High-grade surface (juxtacortical high grade)

Other high-grade osteosarcomas include:

• Pagetoid: a tumor that develops in someone with Paget disease of the bone
• Extraskeletal: a tumor that starts in a part of the body other than a bone (but still makes bone tissue)
• Post-radiation: a tumor that starts in a bone that had once been exposed to radiation

Intermediate-grade osteosarcomas

These uncommon tumors fall between high-grade and low-grade osteosarcomas. (They are usually treated the same way as low-grade osteosarcomas.)

• Periosteal (juxtacortical intermediate grade)

Low-grade osteosarcomas

These are the slowest-growing osteosarcomas. The tumors look more like normal bone and have few dividing cells when seen with a microscope.

• Parosteal (juxtacortical low grade)
• Intramedullary or intraosseous well-differentiated (low-grade central)

The grade of the tumor plays a role in determining its stage and the type of treatment used. For more on staging, see Osteosarcoma Stages.

Other types of bone tumors

Several other types of tumors can start in the bones.

Malignant (cancerous) bone tumors

Ewing tumors (Ewing sarcomas) are the second most common bone cancer in children. They are described in Ewing Family of Tumors.

Most other types of bone cancers are usually found in adults and are uncommon in children. These include:

• Chondrosarcoma (cancer that develops from cartilage)
• Undifferentiated pleomorphic sarcoma (UPS) of bone, previously known as malignant fibrous histiocytoma (MFH) of bone
• Fibrosarcoma of bone
• Chordoma
• Malignant giant cell tumor of bone

Numerous malignancies, especially those that affect adults and start in other body parts, can travel to the bones. Although they are not real bone tumors, these are occasionally referred to as metastatic bone cancers. Prostate cancer, for example, is still treated as such even if it has spread to the bones.

Benign (non-cancerous) bone tumors

Not all bone tumors are cancer. Benign bone tumors do not spread to other parts of the body. They are usually not life-threatening, and surgery can often remove them completely. There are many types of benign bone tumors, including:

• Osteoma
• Chondroma
• Osteochondroma
• Eosinophilic granuloma of bone
• Non-ossifying fibroma
• Enchondroma
• Benign giant cell tumor of bone
• Lymphangioma
  

Osteosarcoma is the most frequent primary malignant bone tumor, which mainly occurs in adolescents and young adults. It grows from the cells of osteoblasts, which form bones, and usually originates in the metaphysis of long bones, particularly near the knee (proximal tibia or distal femur) and proximal humerus. The cancer is known for its aggressive behavior, fast growth, and tendency to metastasize, mainly into the lungs.

The specific etiology of osteosarcoma is unknown, though genetic susceptibility and prior radiation exposure are felt to be contributing factors. Symptoms are usually localized pain, swelling, and decreased range of motion. Diagnosis by imaging and biopsy needs to occur early in the course of the disease to optimize treatment, which is usually surgery along with chemotherapy. Progress in limb-salvage surgery and targeted therapies has increased survival in the past few years.

Osteosarcoma occurs with a yearly incidence of about 3 to 4 cases per million individuals all over the world. It occurs most commonly among 10-30 year olds, with the appearance of a second smaller peak in persons older than 60 years of age who have a history of Paget’s disease or prior radiation.

Males are more affected than females, with a male-to-female ratio of 1.4:1. The tumor most commonly involves the long bones of the limbs, with approximately 50-60% of cases involving the area around the knee. Metastatic disease is observed in about 20% of cases at presentation, very much influencing the prognosis.

Geographically, osteosarcoma incidence is fairly even in the majority of regions, though there are slightly elevated rates in African-American groups versus Caucasians. With increased research and improvement in therapy, the 5-year survival rate for localized osteosarcoma is currently approximately 60-70%, though this drops dramatically in metastatic disease.

The exact cause of osteosarcoma is not fully understood, but several risk factors and genetic abnormalities are associated with its development. Key causes include:

1. Genetic Mutations
   • Mutations in tumor suppressor genes like TP53 (p53 gene) and RB1 (retinoblastoma gene).
   • Loss of regulation in the cell cycle, leading to uncontrolled cell division.
2. Hereditary Syndromes
   • Individuals with hereditary conditions such as Li-Fraumeni syndrome and Retinoblastoma have a higher risk.
   • Rothmund-Thomson syndrome and Bloom syndrome are also linked to osteosarcoma.
3. Previous Radiation Therapy
   • Exposure to high-dose radiation, often during cancer treatment, can damage bone tissue and increase the risk of osteosarcoma.
4. Paget’s Disease of Bone
   • In older adults, Paget’s disease, a condition characterized by abnormal bone growth, can sometimes transform into osteosarcoma.
5. Rapid Bone Growth
   • Adolescents experiencing growth spurts are more susceptible, possibly due to increased bone cell activity.
6. Bone Disorders
   • Fibrous Dysplasia and other benign bone conditions may predispose individuals to malignancy.
7. Chemical and Environmental Exposure
   • While not conclusively proven, long-term exposure to certain chemicals or toxins may contribute to bone cancer development.
8. Genetic Predisposition
   • A family history of bone cancer or other cancers can increase the likelihood of osteosarcoma.
9. Chronic Bone Infections or Injuries
   • Although rare, chronic bone infections or trauma may act as a contributing factor in susceptible individuals.

Bone pain and swelling

The most typical symptom of osteosarcoma is pain at the location of the tumor in the bone. The knee or the upper arm are the most typical locations for these tumors in younger individuals, though they can also develop in other bones. The pain may not initially be persistent and may worsen at night. When moving about, the pain frequently gets worse, and if the tumor is in a leg bone, it can cause a limp.

Another typical sign is localized swelling, although this may not happen right away. You might be able to feel a lump or mass, depending on where the tumor is located.

Limb swelling and soreness are extremely typical in healthy, active kids and teenagers. They might not immediately prompt a trip to the doctor because they are considerably more likely to be brought on by typical knocks and bruises. Such an event could postpone a diagnosis. Consult a doctor if your child experiences these symptoms and they don’t go away within a few weeks (or if they worsen) so that the reason may be determined and, if necessary, treated.

Adults are less likely to experience these symptoms; thus, they should prompt an earlier visit to the doctor.

Bone fractures

Although fractures (breaks) are rare, osteosarcoma may weaken the bone in which it develops. Rare telangiectatic osteosarcomas are an exception since they have a tendency to weaken bones more than other types of osteosarcoma and are more likely to result in fractures where the tumor is located.

People who have fractures near to or through osteosarcomas frequently report that a limb was achy for a few months before the fracture, at which point it became excruciatingly painful.

In brief, the following are the systems:

The most common symptoms of osteosarcoma include

• Bone pain or tenderness.
• A mass or lump (tumor) that is warm and might be felt through your skin.
• Swelling and redness at the site of your tumor.
• Increased pain with lifting (if it affects your arm).
• Limping (if it affects your leg).
• Limited movement (if it affects a joint).
• Unexplained fever.
• Broken bone

A comprehensive history and physical examination will be conducted first by your healthcare practitioner. They will inquire about your symptoms and medical background, such as any prior radiation therapy or whether any members of your family have a history of particular inherited problems. Additionally, lumps that might be coming out of bones will be searched for.

When making the diagnosis, your healthcare professional could also employ a few tests. These consist of:

• Blood tests: These tests can provide information about blood counts and how your organs (such as your kidneys and liver) are working. There is no blood test to detect the presence of a bone tumor.
• X-ray: An X-ray will be done to look for abnormal growths in your bones.
• Computed tomography (CT): CT uses computers to combine many X-ray images into cross-sectional views of the inside of your body. This test is used to look for any tumors in your lungs.
• Magnetic resonance imaging (MRI): MRI uses a large magnet, radio waves and a computer to create clear images of body parts. This may be ordered for more detailed pictures if an X-ray is not normal.
• Bone scan: This test uses a small amount of radioactive material injected into your body to identify bone disorders.
• ET scan: This test uses a special glucose tracer that shows the areas in your body where the glucose uptake is extra high. This tracer is often taken up in high concentrations in cancer cells.
• Biopsy: This is a procedure in which a piece of tissue from the affected area is removed so that it can be studied for cancer cells. The two most likely types of biopsy your healthcare provider will use are a core needle biopsy or a surgical biopsy.

Finding out whether the cancer cells have spread or stayed confined is the next step once your healthcare practitioner diagnoses osteosarcoma. “Staging” is the term for this. The malignancy may spread through your lymphatic system, tissues, or blood. The cancer is still referred to as osteosarcoma and not lung cancer if it spreads to your lungs. One may employ the following diagnostic instruments:

• X-ray: Organs such as other bones or your lungs will be X-rayed.
• Computed tomography: Another CT scan will also be performed. This method is the best type of scan for evaluating your lungs.
• PET-CT: This test combines the images from the CT scan and a PET scan.
• MRI: Another MRI may be needed to get detailed pictures of other sites of cancer.
• Bone scan: A bone scan will see if the cancer cells have spread to other bones.

Surgery

The damaged bone will have the tumor and some surrounding healthy tissue removed during surgery. Surgery may usually be performed on an arm or leg without having to amputate it. It is referred to as limb-salvage surgery. Those whose cancer has not spread past the primary site may be candidates for these procedures.

To restore the bone that was removed during surgery, artificial implants or bone harvested from another area of your body may occasionally be utilized. Unfortunately, there are occasional situations where an arm or limb must be completely amputated. Thereafter, you’ll receive an artificial limb or prosthesis.

Chemotherapy

Drugs are used in this manner to eradicate cancer cells. Prior to surgery, chemotherapy is administered to reduce the size of the tumor and eradicate any cancer cells that may be present in the blood. Chemotherapy is also administered following surgery to remove any remaining cancer cells.

Neoadjuvant chemotherapy, which is what it is known as before surgery, normally lasts 10 weeks. Adjuvant chemotherapy refers to chemotherapy administered following surgery to eradicate any cancer cells still present. Adjuvant chemotherapy for osteosarcoma typically lasts an extra 18 weeks.

Radiation therapy

Osteosarcoma can occasionally be treated with radiation. This feature is especially crucial in regions where surgery is not an option. Radiation therapy comes in two varieties: external and internal. The external form makes use of a device that directs radiation at the diseased part of the body. Injecting the material using a needle or catheter is known as internal radiation treatment.

Some individuals with osteosarcoma are treated with bone-seeking radiopharmaceuticals (samarium or radium), which are absorbed by the cancer cells that cause the disease and deliver radiation directly to the site of the malignancy.

Targeted therapy

Utilizing medications that stop the activity of certain proteins vital to cancer cells is known as targeted treatment. Unlike chemotherapy or radiation, these medications often don’t kill normal cells as much. The most widely utilized medications include kinase inhibitor therapy, mammalian target of rapamycin inhibitors, and monoclonal antibody therapy.

Cryosurgery

Liquid nitrogen is used to freeze and destroy cancer cells.

Amputation

Amputation is the surgical removal of a limb. Such an event is rare.

Rotationplasty

The distal femur, or the part of the leg just above the knee, is where cancers are treated with this surgery. The lower leg is rotated 180 degrees and reattached utilizing the ankle as a new knee after the tumor has been excised and a portion of it has been amputated. This approach makes the above-knee amputation more functional and makes it easier to fit a prosthesis. If a rotationplasty is an option, your doctor will go over the cosmetic side effects with you.

While there is no guaranteed way to prevent osteosarcoma, especially since many cases are linked to genetic factors or spontaneous mutations, certain strategies can help reduce the risk or aid in early detection. These include:

1. Genetic Counseling and Screening
   • Individuals with a family history of cancers or genetic syndromes like Li-Fraumeni syndrome or retinoblastoma should consider genetic counseling for early identification of risks.
2. Regular Medical Check-ups
   • Routine health check-ups and monitoring for individuals at higher risk, especially those with prior radiation exposure or bone disorders, can help in early detection.
3. Avoidance of Radiation Exposure
   • Limiting unnecessary exposure to radiation, particularly in children and adolescents, can reduce the risk of radiation-induced osteosarcoma.
4. Managing Bone Conditions
   • Effective management of conditions like Paget’s disease and other bone abnormalities may lower the risk of malignant transformation.
5. Healthy Lifestyle
   • Maintaining a balanced diet rich in calcium and vitamin D supports bone health.
   • Engaging in regular physical activity can strengthen bones and improve overall well-being.
6. Avoiding Carcinogen Exposure
   • Reducing exposure to known carcinogens, such as certain chemicals or toxins, may contribute to overall cancer prevention.
7. Monitoring After Cancer Treatment
   • Cancer survivors who have undergone radiation therapy should undergo regular screenings to monitor for secondary malignancies like osteosarcoma.

While osteosarcoma cannot always be prevented, adopting these measures may help in early detection and prompt treatment, leading to better outcomes.

The prognosis of osteosarcoma depends on various factors, including the stage at diagnosis, tumor size, location, presence of metastasis, and the patient’s overall health. With advancements in treatment, particularly chemotherapy and surgical techniques, the survival rate has significantly improved recently.

Factors Affecting Prognosis

1. Stage at Diagnosis
   • Localized Osteosarcoma (confined to the bone) has a better prognosis, with a 5-year survival rate of approximately 60-70%.
2. Metastatic Disease
   • If the cancer has spread to the lungs or other bones, the 5-year survival rate drops to around 20-30%.
3. Tumor Response to Chemotherapy
   • Patients whose tumors respond well to pre-surgical chemotherapy tend to have a better prognosis.
4. Location of Tumor
   • Tumors in the limbs generally have a more favorable outcome compared to tumors in the pelvis, spine, or skull.
5. Age and Overall Health
   • Younger patients typically respond better to aggressive treatment than older adults or those with underlying health conditions.

Long-Term Outlook

• Limb-Salvage Surgery and Rehabilitation: Many patients can regain mobility and maintain a good quality of life with modern limb-salvage procedures.
• Regular Monitoring: Survivors require long-term follow-ups to detect recurrence or monitor potential side effects of treatment, such as secondary cancers or heart damage from chemotherapy.
• Psychosocial Support: Emotional and psychological support plays a significant role in helping survivors adapt to life after treatment.

Overall, early diagnosis and a multidisciplinary approach to treatment significantly improve survival and enhance the quality of life for osteosarcoma patients.
