Specific treatment for osteoblastoma will be determined by your child's physician based on:
- your child's age, overall health, and medical history
- extent of the disease
- location of the tumor
- your child's tolerance for specific medications, procedures, or therapies
- how your child's physician expects the disease may progress
- your opinion or preference
Treatment for osteoblastoma usually involves an operation to remove the tumor performed by an orthopaedic surgeon. In some cases, if the tumor cannot be completely removed, adjuvant therapies described below may be used. The following surgical procedures are among those used to treat osteoblastoma:
- En bloc resection: If more aggressive resection of the tumor is warranted, the operation will likely involve en bloc resection, which is the surgical removal of bone containing the tumor. Internal fixation, with pins, may be required to restore the structural integrity of the bone.
- Curettage/Bone Grafting: Curettage describes a surgical scraping of the cyst with a special instrument called a curette that has a scoop, loop or ring at its tip. This procedure may be opted for if the tumor cannot be removed by excision. Sometimes, the remaining cavity is then packed with donor bone tissue (allograft), bone chips taken from another bone (autograft), or other materials depending on the preference of the surgeon.
- Biopsy: During the operation, doctors will take a tissue sample of the tumor so the diagnosis can be confirmed under a microscope.
What is the long-term outlook for a patient with an osteoblastoma?
Prognosis for osteoblastoma is generally excellent, although prognosis varies from individual to individual depending on:
- how active the tumor is
- the tumor's response to therapy
- the age and overall health of your child
- your child's tolerance for specific medication, procedures or therapies.
Most of these tumors can be successfully treated. However, recurrence can occur. Continuous follow-up care is essential for the successful treatment of an osteoblastoma. A schedule of follow-up care should be determined by your child's physician and other members of your care team to monitor ongoing response to treatment and possible late effects of treatment.
