Malignant Bone Tumors

Malignant Bone Tumor Los AngelesWhen a person in Los Angeles is diagnosed with malignant bone tumors, it is often the result of metastasis, meaning the tumors originated in one part of the body and gradually spread to the bones. However, there are several forms of cancer that also originate in the bones, some are more commonly found in children, others tend to affect adults more often.

The treatment and prognosis for bone cancer will vary according to a number of factors, such as the type, stage, size, and location of the tumors, as well as the patient’s overall health profile, among other things. After a primary or metastatic cancer diagnosis, working with a surgeon with a proven track record of specialization in orthopedic tumors and limb preservation is very important.

Different Types of Malignant Bone Sarcomas

There are many different forms of bone tumors, many of which are categorized as subgroups of specific types of cancer. A sarcoma is a type of malignant tumor usually found in connective tissue like muscles, ligaments, and fat cells. They can also grow in bone tissue and anywhere in the body, most commonly in the arms and legs. Sarcomas are fairly rare in adults, but tend to account for as many as 15% of childhood cancer diagnoses.

Osteosarcoma

Osteosarcomas are the most common malignant bone tumors diagnosed in children and teenagers. It is a rare form of cancer, and usually originates in the long bones of the arms and legs. The most common symptoms are pain and inflammation and swelling, which can result in difficulty walking and lead to limping in the affected leg.

Like other types of cancer, osteosarcomas range from low to high grade. High grade tumors are the fastest growing, with the most abnormal cell division when viewed under a microscope. Low grade are the slowest, and most resemble normal healthy bone when viewed under a microscope.

The most common types of osteosarcomas include:

  • Chondroblastic
  • Fibroblastic
  • Osteoblastic
  • Pagetoid (associated with a condition known as Paget’s disease)
  • Small cell
  • Telangiectatic
  • Mixed
  • Periosteal
  • Parosteal
  • Intramedullary/intraosseous

Ewing’s Sarcoma

Ewing’s sarcoma is a very rare form of primary bone cancer that almost always affects children and teenagers. Less common than osteosarcomas, it accounts for an estimated 1% of childhood cancer diagnoses. The symptoms can be similar to other types of bone cancer and other illnesses, such as pain and localized swelling in the affected arm or leg. Ewing’s tumors are most common in the arms, legs, pelvis, ribs, and shoulder blades, but can develop in other parts of the body as well.

Chondrosarcoma

This tumor is a type of sarcoma that mainly affects the cells that produce cartilage. Chondrosarcomas are the second most common type of primary bone tumors after osteosarcomas, and the prognosis for patients diagnosed with this type of bone malignancy depends on the location and grade of the tumors. Chondrosarcomas in the arms and legs, for example, generally tend to have better outcomes than those diagnosed in other parts of the body.

Malignant Fibrous Histiocytoma (MFH)

This is a type of soft tissue sarcoma that can also develop in the bones, and is most commonly diagnosed in the legs, but can also be found in the arms and abdomen. Unlike other forms of soft tissue cancers, this type of sarcoma is more common among middle aged and older adults, and is generally rare in children and young adults. MFH is a primary bone cancer, but can metastasize (spread) to other organs and parts of the body.

Fibrosarcoma

Like MFH, fibrosarcoma usually develops in soft tissue like muscle and fat cells, but can also originate in bone. It is most common among older men and women, and typically affects the bones in the legs, arms, and jaw.

Metastatic Bone Cancers and Treatment in Los Angeles

Primary bone cancers can technically develop anywhere in the body, including the skull, hip bones, arms, legs, and pelvis. Cancer that originates in another part of the body, like the kidneys, liver, or breasts, and then spreads to the bones is known as metastatic cancer. Treatment for soft tissue sarcomas and primary and metastatic bone cancer has a higher likelihood of success when the tumors are diagnosed early and are at a lower grade. Because many types of primary bone cancers are prone to affecting the arms and legs, limb preservation is a high priority and a main focus of treatment for Dr. Daniel C. Allison.

Treatment for malignant bone tumors and soft tissue tumors can involve a combination of surgery, chemotherapy, and radiation, followed by a bone and tissue reconstruction procedure when necessary.
