Osteosarcoma Guide: Stages, Treatment, Side Effects and Patient Journey

Osteosarcoma is a type of bone cancer that most often develops in the long bones of the arms and legs. It typically occurs in teenagers and young adults but can appear at any age. The disease can be aggressive, and early diagnosis is important to guide treatment. Patients may notice pain, swelling or reduced mobility near the affected bone. Osteosarcoma can be classified by stage, which helps determine the best treatment strategy and expected outcomes.

What Does an Osteosarcoma Diagnosis Look Like?

Diagnosis usually begins with a physical exam and medical history. Imaging tests such as X-rays, MRI or CT scans can identify suspicious areas. A biopsy is required to confirm osteosarcoma and evaluate the tumor’s grade. Doctors may also order blood tests to assess overall health and detect markers that could indicate cancer spread.

Camille Wahl received a diagnosis of osteosarcoma in 2013 when she was 10 years old. An Irish step dancer from the age of 3, she noticed a bump on her shin one day after class, which had been preceded by some pain in the area.

In an interview with CURE, she said, “I was a little bit worried and thought I should probably tell my parents about this, so from there I got an x-ray, which led to an MRI and a bone biopsy, and that biopsy showed that I had high-grade osteosarcoma,” said Wahl, who lives in Massachusetts. “It took up about three-fourths of my tibia bone in my right leg and by the time it was found, it was also spread to both my lungs, so I was metastatic at diagnosis.”

Stage 1 Osteosarcoma Treatment Options

Stage 1 osteosarcoma is usually localized and has not spread to nearby lymph nodes or distant organs. Early-stage disease is often treated with surgery to remove the tumor, sometimes combined with chemotherapy to reduce recurrence risk. Patients have a relatively favorable prognosis at this stage.

Frontline: Surgery to remove the tumor, often combined with chemotherapy before or after surgery.

Second-Line: Additional chemotherapy if the tumor does not respond or recurs.

Third-Line and Beyond: Consideration of clinical trials or targeted therapies for persistent disease.

Stage 2 Osteosarcoma Treatment Options

Stage 2 osteosarcoma is larger or higher grade, but still primarily confined to the bone. Treatment often requires more extensive surgery and combination chemotherapy to ensure all cancer cells are targeted. Close monitoring is essential to detect any early signs of recurrence.

Frontline: Surgery and combination chemotherapy tailored to tumor size and location.

Second-Line: Intensified chemotherapy or limb-sparing surgical approaches.

Third-Line and Beyond: Experimental treatments, immunotherapy or referral to specialized centers.

Stage 3 Osteosarcoma Treatment Options

Stage 3 osteosarcoma may involve multiple areas of the bone or adjacent tissues. Treatment is aggressive, often combining high-dose chemotherapy with complex surgical approaches. A multidisciplinary team usually coordinates care to maximize effectiveness and preserve function.

Frontline: Aggressive surgery and high-dose chemotherapy, often coordinated by a multidisciplinary team.

Second-Line: Salvage chemotherapy or repeat surgery if feasible.

Third-Line and Beyond: Enrollment in clinical trials for novel agents or therapies.

How to Treat Metastatic Osteosarcoma?

Metastatic osteosarcoma has spread to other parts of the body, such as the lungs or other bones. Treatment focuses on controlling the disease, reducing symptoms and maintaining quality of life. Surgery, systemic chemotherapy and targeted therapies may all be considered depending on the patient’s condition and goals.

Frontline: Systemic chemotherapy, possibly combined with surgery to remove primary or metastatic tumors.

Second-Line: Alternative chemotherapy regimens or targeted therapies to control spread.

Third-Line and Beyond: Experimental treatments, palliative care options and supportive care to maintain quality of life.

What are the Side Effects of Osteosarcoma Treatment?

Treatment can cause side effects that vary by therapy. Chemotherapy may lead to fatigue, nausea, hair loss and lowered blood counts. Surgery may result in pain, limited mobility or need for rehabilitation. Radiation, rarely used in osteosarcoma, can cause skin changes or localized discomfort. Discussing potential side effects with the care team helps manage symptoms and maintain daily activities.

Conclusion

Osteosarcoma requires a coordinated approach between patients, families and oncology teams. Early detection, accurate staging, and tailored treatment plans improve outcomes. Patients are encouraged to ask questions, seek support services, and discuss participation in clinical trials. Understanding the disease and potential side effects can empower patients to make informed decisions and actively participate in their care.
