Bone Cancer Surgery Options for the Young Patient

Both the distal femur and proximal tibia are commonanatomic sites for primary and metastatic bone tumors. These tumorswere traditionally treated with arthrodesis or amputation of theaffected extremity and resulted in unfavorable functional andpsychologic outcomes (,). However, the prognosis of the sarcomapatients has recently improved as a result of a betterunderstanding of tumor biology, refined chemotherapeutic protocols,advances in diagnostic imaging and improvements in surgicaltechniques. Improvements in the survival of sarcoma patients madethese drawbacks not only more pronounced, but also promoted thedevelopment of new surgical reconstructive procedures whichpromised more useful limb function. Simon compared theresults of limb-sparing resections to those of amputation in 227patients with distal femoral osteosarcoma, and concluded that thelimb salvage surgery did not shorten the disease-free interval orcompromise the long-term survival of these patients compared toamputation ().

There are different staging systems used for bone cancer. One is the TNM staging system.

Surgery usually involves removing the cancer, the affected bone along with some healthy tissue around it. Bones from other parts of the body may be used to replace the bone that was removed.

The cancer is high-grade and is in more than one place in the bone where it started.

There are many aspects to be considered when rehabilitating a cancer patient with large bone and soft tissue defects. The patient may have a limited life expectancy due to the cancer, as it may recur and/or metastasize. Also, the patient may have other diseases that affect rehabilitation. The use of a facial prosthesis allows inspection of the area to check for possible cancer recurrence. Anchoring the prosthesis on extra-oral implants is secure for the patient in comparison to anchoring it by glue (,).

Head and neck cancer surgery may be mutilating, leaving the patient with large craniofacial defects; however, such surgery may be necessary in order to save the patient’s life. Radiotherapy and chemotherapy contribute to cancer treatment, but in certain cases these treatments may only be performed following surgery, as they may affect tissues and alter the healing process (,). Rehabilitation following cancer therapy may therefore be compromising in several ways, and lead to complications such as reduced healing capacity, wound infections, graft necrosis and implant failures.

Rehabilitation is not only useful for improved cosmetic appearance but also helps to promote function and social rehabilitation (). In a case such as this, it was important to close the defect of the hard palate with a dental prosthesis to improve speech, chewing and swallowing function. Secondly, it was important to cover the frontal part of the brain with the facial prosthesis. This can be done in several ways; for example, by bone grafting or by covering the defect with a titanium or acrylic plate. By utilizing modern techniques for 3-D imaging and rapid prototyping, well-fitting plates can be constructed and implanted ().

Many things can cause these symptoms other than cancer. However, if you have bone pain, especially if it occurs at night, or any swelling, you should get it checked by your doctor.

The doctor will take a sample of cells () to be checked by a pathologist (a doctor that specialises in cell types). If your doctor thinks you have bone cancer, the biopsy should be done at a specialist bone cancer centre.

Chondrosarcoma is a rare type of bone cancer

The exact causes of primary bone cancer are unknown. Osteosarcoma is thought to be related to periods of rapid bone growth, such as puberty. Adults who have a bone condition called Paget’s disease or who have previously been treated with radiotherapy may have a slightly increased risk of developing osteosarcoma. Rarely, some osteosarcomas may occur in people from families where there is an inherited faulty gene that increases the risk of developing several types of cancer, such as Li-Fraumeni syndrome.

Osteosarcoma is a rare type of cancer that can develop in a bone.

This type of biopsy is not often used, as the needle biopsy is much quicker and simpler. In an open biopsy, a small piece of bone is removed during a small operation while you are under a general anaesthetic. You may need this if a needle biopsy cannot be done or does not give a clear result.

Another type of cancer that affects the bone is Ewing's sarcoma

Osteosarcoma usually develops in growing bones. Although it can occur at any age, it is most often found in and is slightly more common in males. Any bone in the body can be affected, but the most common sites are the arms or legs, especially around the knee joint.

Authors: Mrs Lynne Bowlen* Dr Timothy Cain * What is a bone scan

Major improvements have been made in . In the past, the surgeon often needed to remove (amputate) the affected limb if osteosarcoma was found. Now they often remove just the affected part of the bone and some of the healthy tissue around it. The bone is then replaced with a specially-designed metal replacement (prosthesis) or a bone graft (bone taken from another part of the body). If the cancer affects a bone in or near a joint, the whole joint can often be replaced with an artificial one. This operation is called .
